The +problem is the restrictions on the use of the manual. Free manuals +are available in source code form, and give you permission to copy and +modify. Non-free manuals do not allow this. + +The criteria of freedom for a free manual are roughly the same as for +free software. Redistribution (including the normal kinds of +commercial redistribution) must be permitted, so that the manual can +accompany every copy of the program, both on-line and on paper. + +Permission for modification of the technical content is crucial too. +When people modify the software, adding or changing features, if they +are conscientious they will change the manual too---so they can +provide accurate and clear documentation for the modified program. A +manual that leaves you no choice but to write a new manual to document +a changed version of the program is not really available to our +community. + +Some kinds of limits on the way modification is handled are +acceptable. For example, requirements to preserve the original +author's copyright notice, the distribution terms, or the list of +authors, are ok. It is also no problem to require modified versions +to include notice that they were modified. Even entire sections that +may not be deleted or changed are acceptable, as long as they deal +with nontechnical topics (like this one). These kinds of restrictions +are acceptable because they don't obstruct the community's normal use +of the manual. + +However, it must be possible to modify all the @emph{technical} +content of the manual, and then distribute the result in all the usual +media, through all the usual channels. Otherwise, the restrictions +obstruct the use of the manual, it is not free, and we need another +manual to replace it. + +Please spread the word about this issue. Our community continues to +lose manuals to proprietary publishing. If we spread the word that +free software needs free reference manuals and free tutorials, perhaps +the next person who wants to contribute by writing documentation will +realize, before it is too late, that only free manuals contribute to +the free software community. + +If you are writing documentation, please insist on publishing it under +the GNU Free Documentation License or another free documentation +license. Remember that this decision requires your approval---you +don't have to let the publisher decide. Some commercial publishers +will use a free license if you insist, but they will not propose the +option; it is up to you to raise the issue and say firmly that this is +what you want. If the publisher you are dealing with refuses, please +try other publishers. If you're not sure whether a proposed license +is free, write to @email{licensing@@gnu.org}. + +You can encourage commercial publishers to sell more free, copylefted +manuals and tutorials by buying them, and particularly by buying +copies from the publishers that paid for their writing or for major +improvements. Meanwhile, try to avoid buying non-free documentation +at all. Check the distribution terms of a manual before you buy it, +and insist that whoever seeks your business must respect your freedom. +Check the history of the book, and try reward the publishers that have +paid or pay the authors to work on it. + +The Free Software Foundation maintains a list of free documentation +published by other publishers, at +@url{http://www.fsf.org/doc/other-free-books.html}. diff -durpN glibc-2.2.4/manual/getopt.texi glibc-2.2.5/manual/getopt.texi --- glibc-2.2.4/manual/getopt.texi Mon Jul 23 10:54:40 2001 +++ glibc-2.2.5/manual/getopt.texi Wed Oct 31 00:30:48 2001 @@ -224,7 +224,7 @@ was seen. @comment getopt.h @comment GNU -@deftypefun int getopt_long (int @var{argc}, char *const *@var{argv}, const char *@var{shortopts}, struct option *@var{longopts}, int *@var{indexptr}) +@deftypefun int getopt_long (int @var{argc}, char *const *@var{argv}, const char *@var{shortopts}, const struct option *@var{longopts}, int *@var{indexptr}) Decode options from the vector @var{argv} (whose length is @var{argc}).

The `gconv-modules' files are line-oriented text -files, where each of the lines has one of the following formats: + The functions described in the previous chapter are defined in +Amendment 1 to ISO C90, but the original ISO C90 standard also +contained functions for character set conversion. The reason that +these original functions are not described first is that they are almost +entirely useless. - * If the first non-whitespace character is a `#' the line contains - only comments and is ignored. + The problem is that all the conversion functions described in the +original ISO C90 use a local state. Using a local state implies that +multiple conversions at the same time (not only when using threads) +cannot be done, and that you cannot first convert single characters and +then strings since you cannot tell the conversion functions which state +to use. - * Lines starting with `alias' define an alias name for a character - set. There are two more words expected on the line. The first one - defines the alias name and the second defines the original name of - the character set. The effect is that it is possible to use the - alias name in the FROMSET or TOSET parameters of `iconv_open' and - achieve the same result as when using the real character set name. + These original functions are therefore usable only in a very limited +set of situations. One must complete converting the entire string +before starting a new one, and each string/text must be converted with +the same function (there is no problem with the library itself; it is +guaranteed that no library function changes the state of any of these +functions). *For the above reasons it is highly requested that the +functions described in the previous section be used in place of +non-reentrant conversion functions.* - This is quite important as a character set has often many different - names. There is normally always an official name but this need not - correspond to the most popular name. Beside this many character - sets have special names which are somehow constructed. E.g., all - character sets specified by the ISO have an alias of the form - `ISO-IR-NNN' where NNN is the registration number. This allows - programs which know about the registration number to construct - character set names and use them in `iconv_open' calls. More on - the available names and aliases follows below. +* Menu: - * Lines starting with `module' introduce an available conversion - module. These lines must contain three or four more words. +* Non-reentrant Character Conversion:: Non-reentrant Conversion of Single + Characters. +* Non-reentrant String Conversion:: Non-reentrant Conversion of Strings. +* Shift State:: States in Non-reentrant Functions. - The first word specifies the source character set, the second word - the destination character set of conversion implemented in this - module. The third word is the name of the loadable module. The - filename is constructed by appending the usual shared object - suffix (normally `.so') and this file is then supposed to be found - in the same directory the `gconv-modules' file is in. The last - word on the line, which is optional, is a numeric value - representing the cost of the conversion. If this word is missing - a cost of 1 is assumed.

All what has to -be done is to put the new module, be its name ISO2022JP-EUCJP.so, in a -directory and add a file `gconv-modules' with the following content in -the same directory: +Non-reentrant Conversion of Single Characters +--------------------------------------------- - module ISO-2022-JP// EUC-JP// ISO2022JP-EUCJP 1 - module EUC-JP// ISO-2022-JP// ISO2022JP-EUCJP 1 + - Function: int mbtowc (wchar_t *restrict RESULT, const char *restrict + STRING, size_t SIZE) + The `mbtowc' ("multibyte to wide character") function when called + with non-null STRING converts the first multibyte character + beginning at STRING to its corresponding wide character code. It + stores the result in `*RESULT'. - To see why this is sufficient, it is necessary to understand how the -conversion used by `iconv' (and described in the descriptor) is -selected. The approach to this problem is quite simple. + `mbtowc' never examines more than SIZE bytes. (The idea is to + supply for SIZE the number of bytes of data you have in hand.) - At the first call of the `iconv_open' function the program reads all -available `gconv-modules' files and builds up two tables: one -containing all the known aliases and another which contains the -information about the conversions and which shared object implements -them. + `mbtowc' with non-null STRING distinguishes three possibilities: + the first SIZE bytes at STRING start with valid multibyte + characters, they start with an invalid byte sequence or just part + of a character, or STRING points to an empty string (a null + character). -Finding the conversion path in `iconv' -...................................... + For a valid multibyte character, `mbtowc' converts it to a wide + character and stores that in `*RESULT', and returns the number of + bytes in that character (always at least 1 and never more than + SIZE). - The set of available conversions form a directed graph with weighted -edges. The weights on the edges are the costs specified in the -`gconv-modules' files. The `iconv_open' function uses an algorithm -suitable for search for the best path in such a graph and so constructs -a list of conversions which must be performed in succession to get the -transformation from the source to the destination character set. + For an invalid byte sequence, `mbtowc' returns -1. For an empty + string, it returns 0, also storing `'\0'' in `*RESULT'. - Explaining why the above `gconv-modules' files allows the `iconv' -implementation to resolve the specific ISO-2022-JP to EUC-JP conversion -module instead of the conversion coming with the library itself is -straightforward. Since the latter conversion takes two steps (from -ISO-2022-JP to ISO 10646 and then from ISO 10646 to EUC-JP) the cost is -1+1 = 2. But the above `gconv-modules' file specifies that the new -conversion modules can perform this conversion with only the cost of 1. + If the multibyte character code uses shift characters, then + `mbtowc' maintains and updates a shift state as it scans.

At + most `MB_CUR_MAX' characters are stored. - A last remark about the `gconv-modules' is about the names not -ending with `//'. There often is a character set named `INTERNAL' -mentioned. From the discussion above and the chosen name it should -have become clear that this is the name for the representation used in -the intermediate step of the triangulation. We have said that this is -UCS-4 but actually it is not quite right. The UCS-4 specification also -includes the specification of the byte ordering used. Since a UCS-4 -value consists of four bytes a stored value is effected by byte -ordering. The internal representation is _not_ the same as UCS-4 in -case the byte ordering of the processor (or at least the running -process) is not the same as the one required for UCS-4. This is done -for performance reasons as one does not want to perform unnecessary -byte-swapping operations if one is not interested in actually seeing -the result in UCS-4. To avoid trouble with endianess the internal -representation consistently is named `INTERNAL' even on big-endian -systems where the representations are identical. + `wctomb' with non-null STRING distinguishes three possibilities + for WCHAR: a valid wide character code (one that can be translated + to a multibyte character), an invalid code, and `L'\0''. -`iconv' module data structures -.............................. + Given a valid code, `wctomb' converts it to a multibyte character, + storing the bytes starting at STRING. Then it returns the number + of bytes in that character (always at least 1 and never more than + `MB_CUR_MAX'). - So far this section described how modules are located and considered -to be used. What remains to be described is the interface of the -modules so that one can write new ones. This section describes the -interface as it is in use in January 1999. The interface will change -in future a bit but hopefully only in an upward compatible way. + If WCHAR is an invalid wide character code, `wctomb' returns -1. + If WCHAR is `L'\0'', it returns `0', also storing `'\0'' in + `*STRING'. - The definitions necessary to write new modules are publicly available -in the non-standard header `gconv.h'. The following text will -therefore describe the definitions from this header file. But first it -is necessary to get an overview. + If the multibyte character code uses shift characters, then + `wctomb' maintains and updates a shift state as it scans. If you + call `wctomb' with a null pointer for STRING, that initializes the + shift state to its standard initial value. It also returns + nonzero if the multibyte character code in use actually has a + shift state. *Note Shift State::. - From the perspective of the user of `iconv' the interface is quite -simple: the `iconv_open' function returns a handle which can be used in -calls to `iconv' and finally the handle is freed with a call to -`iconv_close'. The problem is: the handle has to be able to represent -the possibly long sequences of conversion steps and also the state of -each conversion since the handle is all which is passed to the `iconv' -function. Therefore the data structures are really the elements to -understanding the implementation. + Calling this function with a WCHAR argument of zero when STRING is + not null has the side-effect of reinitializing the stored shift + state _as well as_ storing the multibyte character `'\0'' and + returning 0. - We need two different kinds of data structures. The first describes -the conversion and the second describes the state etc. There are -really two type definitions like this in `gconv.h'. + Similar to `mbrlen' there is also a non-reentrant function that +computes the length of a multibyte character. It can be defined in +terms of `mbtowc'. - - Data type: struct __gconv_step - This data structure describes one conversion a module can perform. - For each function in a loaded module with conversion functions - there is exactly one object of this type. This object is shared - by all users of the conversion. I.e., this object does not - contain any information corresponding to an actual conversion. It - only describes the conversion itself. + - Function: int mblen (const char *STRING, size_t SIZE) + The `mblen' function with a non-null STRING argument returns the + number of bytes that make up the multibyte character beginning at + STRING, never examining more than SIZE bytes. (The idea is to + supply for SIZE the number of bytes of data you have in hand.) - `struct __gconv_loaded_object *__shlib_handle' - `const char *__modname' - `int __counter' - All these elements of the structure are used internally in - the C library to coordinate loading and unloading the shared. - One must not expect any of the other elements be available - or initialized. + The return value of `mblen' distinguishes three possibilities: the + first SIZE bytes at STRING start with valid multibyte characters, + they start with an invalid byte sequence or just part of a + character, or STRING points to an empty string (a null character). - `const char *__from_name' - `const char *__to_name' - `__from_name' and `__to_name' contain the names of the source - and destination character sets. They can be used to identify - the actual conversion to be carried out since one module - might implement conversions for more than one character set - and/or direction. + For a valid multibyte character, `mblen' returns the number of + bytes in that character (always at least `1' and never more than + SIZE). For an invalid byte sequence, `mblen' returns -1. For an + empty string, it returns 0. - `gconv_fct __fct' - `gconv_init_fct __init_fct' - `gconv_end_fct __end_fct' - These elements contain pointers to the functions in the - loadable module. The interface will be explained below. + If the multibyte character code uses shift characters, then `mblen' + maintains and updates a shift state as it scans.

The `__min_needed_from' value specifies how many - bytes a character of the source character set at least needs. - The `__max_needed_from' specifies the maximum value which - also includes possible shift sequences. + The function `mblen' is declared in `stdlib.h'. - The `__min_needed_to' and `__max_needed_to' values serve the - same purpose but this time for the destination character set. + +File: libc.info, Node: Non-reentrant String Conversion, Next: Shift State, Prev: Non-reentrant Character Conversion, Up: Non-reentrant Conversion - It is crucial that these values are accurate since otherwise - the conversion functions will have problems or not work at - all. +Non-reentrant Conversion of Strings +----------------------------------- - `int __stateful' - This element must also be initialized by the init function. - It is nonzero if the source character set is stateful. - Otherwise it is zero. + For convenience the ISO C90 standard also defines functions to +convert entire strings instead of single characters.

It can be used to communicate extra - information from one call to another. It need not be - initialized if not needed at all.

Otherwise, it returns the number + of wide characters stored in the array WSTRING. This number does + not include the terminating null character, which is present if the + number is less than SIZE. - `char *__outbuf' - `char *__outbufend' - These elements specify the output buffer for the conversion - step. The `__outbuf' element points to the beginning of the - buffer and `__outbufend' points to the byte following the - last byte in the buffer. The conversion function must not - assume anything about the size of the buffer but it can be - safely assumed the there is room for at least one complete - character in the output buffer. + Here is an example showing how to convert a string of multibyte + characters, allocating enough space for the result. - Once the conversion is finished and the conversion is the - last step the `__outbuf' element must be modified to point - after last last byte written into the buffer to signal how - much output is available.

This information is necessary for the recursion. See - the description of the conversion function internals below. - This element must never be modified. - `int __invocation_counter' - The conversion function can use this element to see how many - calls of the conversion function already happened. Some - character sets require when generating output a certain - prolog and by comparing this value with zero one can find out - whether it is the first call and therefore the prolog should - be emitted or not. This element must never be modified. + - Function: size_t wcstombs (char *STRING, const wchar_t *WSTRING, + size_t SIZE) + The `wcstombs' ("wide character string to multibyte string") + function converts the null-terminated wide character array WSTRING + into a string containing multibyte characters, storing not more + than SIZE bytes starting at STRING, followed by a terminating null + character if there is room. The conversion of characters begins in + the initial shift state. - `int __internal_use' - This element is another one rarely used but needed in certain - situations. It got assigned a nonzero value in case the - conversion functions are used to implement `mbsrtowcs' et.al. - I.e., the function is not used directly through the `iconv' - interface. + The terminating null character counts towards the size, so if SIZE + is less than or equal to the number of bytes needed in WSTRING, no + terminating null character is stored. - This sometimes makes a difference as it is expected that the - `iconv' functions are used to translate entire texts while the - `mbsrtowcs' functions are normally only used to convert single - strings and might be used multiple times to convert entire - texts. + If a code that does not correspond to a valid multibyte character + is found, the `wcstombs' function returns a value of -1. + Otherwise, the return value is the number of bytes stored in the + array STRING. This number does not include the terminating null + character, which is present if the number is less than SIZE. - But in this situation we would have problem complying with - some rules of the character set specification. Some - character sets require a prolog which must appear exactly - once for an entire text. If a number of `mbsrtowcs' calls - are used to convert the text only the first call must add the - prolog. But since there is no communication between the - different calls of `mbsrtowcs' the conversion functions have - no possibility to find this out. The situation is different - for sequences of `iconv' calls since the handle allows access - to the needed information. + +File: libc.info, Node: Shift State, Prev: Non-reentrant String Conversion, Up: Non-reentrant Conversion - This element is mostly used together with - `__invocation_counter' in a way like this: +States in Non-reentrant Functions +--------------------------------- - if (!data->__internal_use - && data->__invocation_counter == 0) - /* Emit prolog. */ - ... + In some multibyte character codes, the _meaning_ of any particular +byte sequence is not fixed; it depends on what other sequences have come +earlier in the same string. Typically there are just a few sequences +that can change the meaning of other sequences; these few are called +"shift sequences" and we say that they set the "shift state" for other +sequences that follow. - This element must never be modified. + To illustrate shift state and shift sequences, suppose we decide that +the sequence `0200' (just one byte) enters Japanese mode, in which +pairs of bytes in the range from `0240' to `0377' are single +characters, while `0201' enters Latin-1 mode, in which single bytes in +the range from `0240' to `0377' are characters, and interpreted +according to the ISO Latin-1 character set. This is a multibyte code +that has two alternative shift states ("Japanese mode" and "Latin-1 +mode"), and two shift sequences that specify particular shift states. - `mbstate_t *__statep' - The `__statep' element points to an object of type `mbstate_t' - (*note Keeping the state::). The conversion of an stateful - character set must use the object pointed to by this element - to store information about the conversion state. The - `__statep' element itself must never be modified. + When the multibyte character code in use has shift states, then +`mblen', `mbtowc', and `wctomb' must maintain and update the current +shift state as they scan the string. To make this work properly, you +must follow these rules: - `mbstate_t __state' - This element _never_ must be used directly. It is only part - of this structure to have the needed space allocated. + * Before starting to scan a string, call the function with a null + pointer for the multibyte character address--for example, `mblen + (NULL, 0)'. This initializes the shift state to its standard + initial value. -`iconv' module interfaces -......................... + * Scan the string one character at a time, in order. Do not "back + up" and rescan characters already scanned, and do not intersperse + the processing of different strings. - With the knowledge about the data structures we now can describe the -conversion functions itself. To understand the interface a bit of -knowledge about the functionality in the C library which loads the -objects with the conversions is necessary. + Here is an example of using `mblen' following these rules: - It is often the case that one conversion is used more than once. -I.e., there are several `iconv_open' calls for the same set of character -sets during one program run. The `mbsrtowcs' et.al. functions in the -GNU C library also use the `iconv' functionality which increases the -number of uses of the same functions even more. + void + scan_string (char *s) + { + int length = strlen (s); + + /* Initialize shift state. */ + mblen (NULL, 0); + + while (1) + { + int thischar = mblen (s, length); + /* Deal with end of string and invalid characters. */ + if (thischar == 0) + break; + if (thischar == -1) + { + error ("invalid multibyte character"); + break; + } + /* Advance past this character. */ + s += thischar; + length -= thischar; + } + } - For this reason the modules do not get loaded exclusively for one -conversion. Instead a module once loaded can be used by arbitrarily -many `iconv' or `mbsrtowcs' calls at the same time. The splitting of -the information between conversion function specific information and -conversion data makes this possible. The last section showed the two -data structures used to do this. + The functions `mblen', `mbtowc' and `wctomb' are not reentrant when +using a multibyte code that uses a shift state. However, no other +library functions call these functions, so you don't have to worry that +the shift state will be changed mysteriously. - This is of course also reflected in the interface and semantics of -the functions the modules must provide. There are three functions which -must have the following names: + +File: libc.info, Node: Generic Charset Conversion, Prev: Non-reentrant Conversion, Up: Character Set Handling -`gconv_init' - The `gconv_init' function initializes the conversion function - specific data structure. This very same object is shared by all - conversion which use this conversion and therefore no state - information about the conversion itself must be stored in here. - If a module implements more than one conversion the `gconv_init' - function will be called multiple times. +Generic Charset Conversion +========================== -`gconv_end' - The `gconv_end' function is responsible to free all resources - allocated by the `gconv_init' function. If there is nothing to do - this function can be missing. Special care must be taken if the - module implements more than one conversion and the `gconv_init' - function does not allocate the same resources for all conversions. + The conversion functions mentioned so far in this chapter all had in +common that they operate on character sets that are not directly +specified by the functions.

The wide +character set is fixed by the implementation (in the case of GNU C +library it is always UCS-4 encoded ISO 10646. -`gconv' - This is the actual conversion function.

It gets passed the conversion step information - initialized by `gconv_init' and the conversion data, specific to - this use of the conversion functions. + This has of course several problems when it comes to general +character conversion: - There are three data types defined for the three module interface -function and these define the interface. + * For every conversion where neither the source nor the destination + character set is the character set of the locale for the `LC_CTYPE' + category, one has to change the `LC_CTYPE' locale using + `setlocale'. - - Data type: int (*__gconv_init_fct) (struct __gconv_step *) - This specifies the interface of the initialization function of the - module. It is called exactly once for each conversion the module - implements. + Changing the `LC_TYPE' locale introduces major problems for the + rest of the programs since several more functions (e.g., the + character classification functions, *note Classification of + Characters::) use the `LC_CTYPE' category. - As explained int the description of the `struct __gconv_step' data - structure above the initialization function has to initialize - parts of it. + * Parallel conversions to and from different character sets are not + possible since the `LC_CTYPE' selection is global and shared by all + threads. - `__min_needed_from' - `__max_needed_from' - `__min_needed_to' - `__max_needed_to' - These elements must be initialized to the exact numbers of - the minimum and maximum number of bytes used by one character - in the source and destination character set respectively. If - the characters all have the same size the minimum and maximum - values are the same. + * If neither the source nor the destination character set is the + character set used for `wchar_t' representation, there is at least + a two-step process necessary to convert a text using the functions + above. One would have to select the source character set as the + multibyte encoding, convert the text into a `wchar_t' text, select + the destination character set as the multibyte encoding, and + convert the wide character text to the multibyte (= destination) + character set. - `__stateful' - This element must be initialized to an nonzero value if the - source character set is stateful. Otherwise it must be zero. + Even if this is possible (which is not guaranteed) it is a very + tiring work.

The comparison should always be done without - paying attention to the case. +* Menu: - Then a data structure is allocated which contains the necessary - information about which conversion is selected. The data structure - `struct iso2022jp_data' is locally defined since outside the module - this data is not used at all.

A single ISO-2022-JP - character can consist of one to four bytes. Therefore the - `MIN_NEEDED_FROM' and `MAX_NEEDED_FROM' macros are defined this - way. The output is always the `INTERNAL' character set (aka - UCS-4) and therefore each character consists of exactly four - bytes. For the conversion from `INTERNAL' to ISO-2022-JP we have - to take into account that escape sequences might be necessary to - switch the character sets. Therefore the `__max_needed_to' - element for this direction gets assigned `MAX_NEEDED_FROM + 2'. - This takes into account the two bytes needed for the escape - sequences to single the switching. The asymmetry in the maximum - values for the two directions can be explained easily: when - reading ISO-2022-JP text escape sequences can be handled alone. - I.e., it is not necessary to process a real character since the - effect of the escape sequence can be recorded in the state - information. The situation is different for the other direction. - Since it is in general not known which character comes next one - cannot emit escape sequences to change the state in advance. This - means the escape sequences which have to be emitted together with - the next character. Therefore one needs more room then only for - the character itself. + +File: libc.info, Node: Generic Conversion Interface, Next: iconv Examples, Up: Generic Charset Conversion - The possible return values of the initialization function are: +Generic Character Set Conversion Interface +------------------------------------------ - `__GCONV_OK' - The initialization succeeded + This set of functions follows the traditional cycle of using a +resource: open-use-close. The interface consists of three functions, +each of which implements one step. - `__GCONV_NOCONV' - The requested conversion is not supported in the module. - This can happen if the `gconv-modules' file has errors. + Before the interfaces are described it is necessary to introduce a +data type. Just like other open-use-close interfaces the functions +introduced here work using handles and the `iconv.h' header defines a +special type for the handles used. - `__GCONV_NOMEM' - Memory required to store additional information could not be - allocated. + - Data Type: iconv_t + This data type is an abstract type defined in `iconv.h'. The user + must not assume anything about the definition of this type; it + must be completely opaque. - The functions called before the module is unloaded is significantly -easier. It often has nothing at all to do in which case it can be left -out completely. + Objects of this type can get assigned handles for the conversions + using the `iconv' functions. The objects themselves need not be + freed, but the conversions for which the handles stand for have to. - - Data type: void (*__gconv_end_fct) (struct gconv_step *) - The task of this function is it to free all resources allocated in - the initialization function. Therefore only the `__data' element - of the object pointed to by the argument is of interest. - Continuing the example from the initialization function, the - finalization function looks like this: +The first step is the function to create a handle. - void - gconv_end (struct __gconv_step *data) - { - free (data->__data); - } + - Function: iconv_t iconv_open (const char *TOCODE, const char + *FROMCODE) + The `iconv_open' function has to be used before starting a + conversion. The two parameters this function takes determine the + source and destination character set for the conversion, and if the + implementation has the possibility to perform such a conversion, + the function returns a handle. - The most important function is the conversion function itself. It -can get quite complicated for complex character sets. But since this -is not of interest here we will only describe a possible skeleton for -the conversion function. + If the wanted conversion is not available, the `iconv_open' + function returns `(iconv_t) -1'. In this case the global variable + `errno' can have the following values: - - Data type: int (*__gconv_fct) (struct __gconv_step *, struct - __gconv_step_data *, const char **, const char *, size_t *, - int) - The conversion function can be called for two basic reason: to - convert text or to reset the state. From the description of the - `iconv' function it can be seen why the flushing mode is - necessary. What mode is selected is determined by the sixth - argument, an integer. If it is nonzero it means that flushing is - selected. + `EMFILE' + The process already has `OPEN_MAX' file descriptors open. - Common to both mode is where the output buffer can be found. The - information about this buffer is stored in the conversion step - data. A pointer to this is passed as the second argument to this - function. The description of the `struct __gconv_step_data' - structure has more information on this. + `ENFILE' + The system limit of open file is reached. - What has to be done for flushing depends on the source character - set. If it is not stateful nothing has to be done. Otherwise the - function has to emit a byte sequence to bring the state object in - the initial state. Once this all happened the other conversion - modules in the chain of conversions have to get the same chance. - Whether another step follows can be determined from the - `__is_last' element of the step data structure to which the first - parameter points. + `ENOMEM' + Not enough memory to carry out the operation. - The more interesting mode is when actually text has to be - converted. The first step in this case is to convert as much text - as possible from the input buffer and store the result in the - output buffer. The start of the input buffer is determined by the - third argument which is a pointer to a pointer variable - referencing the beginning of the buffer. The fourth argument is a - pointer to the byte right after the last byte in the buffer. + `EINVAL' + The conversion from FROMCODE to TOCODE is not supported. - The conversion has to be performed according to the current state - if the character set is stateful. The state is stored in an - object pointed to by the `__statep' element of the step data - (second argument). Once either the input buffer is empty or the - output buffer is full the conversion stops. At this point the - pointer variable referenced by the third parameter must point to - the byte following the last processed byte. I.e., if all of the - input is consumed this pointer and the fourth parameter have the - same value. + It is not possible to use the same descriptor in different threads + to perform independent conversions. The data structures associated + with the descriptor include information about the conversion state. + This must not be messed up by using it in different conversions. - What now happens depends on whether this step is the last one or - not. If it is the last step the only thing which has to be done - is to update the `__outbuf' element of the step data structure to - point after the last written byte. This gives the caller the - information on how much text is available in the output buffer. - Beside this the variable pointed to by the fifth parameter, which - is of type `size_t', must be incremented by the number of - characters (_not bytes_) which were converted in a non-reversible - way. Then the function can return. + An `iconv' descriptor is like a file descriptor as for every use a + new descriptor must be created. The descriptor does not stand for + all of the conversions from FROMSET to TOSET. - In case the step is not the last one the later conversion - functions have to get a chance to do their work. Therefore the - appropriate conversion function has to be called. The information - about the functions is stored in the conversion data structures, - passed as the first parameter. This information and the step data - are stored in arrays so the next element in both cases can be - found by simple pointer arithmetic: + The GNU C library implementation of `iconv_open' has one + significant extension to other implementations. To ease the + extension of the set of available conversions, the implementation + allows storing the necessary files with data and code in an + arbitrary number of directories. How this extension must be + written will be explained below (*note glibc iconv + Implementation::). Here it is only important to say that all + directories mentioned in the `GCONV_PATH' environment variable are + considered only if they contain a file `gconv-modules'. These + directories need not necessarily be created by the system + administrator. In fact, this extension is introduced to help users + writing and using their own, new conversions. Of course, this + does not work for security reasons in SUID binaries; in this case + only the system directory is considered and this normally is + `PREFIX/lib/gconv'. The `GCONV_PATH' environment variable is + examined exactly once at the first call of the `iconv_open' + function. Later modifications of the variable have no effect. - int - gconv (struct __gconv_step *step, struct __gconv_step_data *data, - const char **inbuf, const char *inbufend, size_t *written, - int do_flush) - { - struct __gconv_step *next_step = step + 1; - struct __gconv_step_data *next_data = data + 1; - ... + The `iconv_open' function was introduced early in the X/Open + Portability Guide, version 2. It is supported by all commercial + Unices as it is required for the Unix branding. However, the + quality and completeness of the implementation varies widely. The + `iconv_open' function is declared in `iconv.h'. - The `next_step' pointer references the next step information and - `next_data' the next data record. The call of the next function - therefore will look similar to this: + The `iconv' implementation can associate large data structure with +the handle returned by `iconv_open'. Therefore, it is crucial to free +all the resources once all conversions are carried out and the +conversion is not needed anymore. - next_step->__fct (next_step, next_data, &outerr, outbuf, - written, 0) + - Function: int iconv_close (iconv_t CD) + The `iconv_close' function frees all resources associated with the + handle CD, which must have been returned by a successful call to + the `iconv_open' function. - But this is not yet all. Once the function call returns the - conversion function might have some more to do. If the return - value of the function is `__GCONV_EMPTY_INPUT' this means there is - more room in the output buffer. Unless the input buffer is empty - the conversion functions start all over again and processes the - rest of the input buffer. If the return value is not - `__GCONV_EMPTY_INPUT' something went wrong and we have to recover - from this. + If the function call was successful the return value is 0. + Otherwise it is -1 and `errno' is set appropriately. Defined + error are: - A requirement for the conversion function is that the input buffer - pointer (the third argument) always points to the last character - which was put in the converted form in the output buffer. This is - trivially true after the conversion performed in the current step. - But if the conversion functions deeper down the stream stop - prematurely not all characters from the output buffer are consumed - and therefore the input buffer pointers must be backed of to the - right position. + `EBADF' + The conversion descriptor is invalid. - This is easy to do if the input and output character sets have a - fixed width for all characters. In this situation we can compute - how many characters are left in the output buffer and therefore - can correct the input buffer pointer appropriate with a similar - computation. Things are getting tricky if either character set - has character represented with variable length byte sequences and - it gets even more complicated if the conversion has to take care - of the state. In these cases the conversion has to be performed - once again, from the known state before the initial conversion. - I.e., if necessary the state of the conversion has to be reset and - the conversion loop has to be executed again. The difference now - is that it is known how much input must be created and the - conversion can stop before converting the first unused character. - Once this is done the input buffer pointers must be updated again - and the function can return. + The `iconv_close' function was introduced together with the rest + of the `iconv' functions in XPG2 and is declared in `iconv.h'. - One final thing should be mentioned. If it is necessary for the - conversion to know whether it is the first invocation (in case a - prolog has to be emitted) the conversion function should just - before returning to the caller increment the - `__invocation_counter' element of the step data structure. See - the description of the `struct __gconv_step_data' structure above - for more information on how this can be used. + The standard defines only one actual conversion function. This has, +therefore, the most general interface: it allows conversion from one +buffer to another. Conversion from a file to a buffer, vice versa, or +even file to file can be implemented on top of it. - The return value must be one of the following values: + - Function: size_t iconv (iconv_t CD, char **INBUF, size_t + *INBYTESLEFT, char **OUTBUF, size_t *OUTBYTESLEFT) + The `iconv' function converts the text in the input buffer + according to the rules associated with the descriptor CD and + stores the result in the output buffer. It is possible to call the + function for the same text several times in a row since for + stateful character sets the necessary state information is kept in + the data structures associated with the descriptor. - `__GCONV_EMPTY_INPUT' - All input was consumed and there is room left in the output - buffer. + The input buffer is specified by `*INBUF' and it contains + `*INBYTESLEFT' bytes. The extra indirection is necessary for + communicating the used input back to the caller (see below). It is + important to note that the buffer pointer is of type `char' and the + length is measured in bytes even if the input text is encoded in + wide characters. - `__GCONV_FULL_OUTPUT' - No more room in the output buffer. In case this is not the - last step this value is propagated down from the call of the - next conversion function in the chain. + The output buffer is specified in a similar way. `*OUTBUF' points + to the beginning of the buffer with at least `*OUTBYTESLEFT' bytes + room for the result. The buffer pointer again is of type `char' + and the length is measured in bytes. If OUTBUF or `*OUTBUF' is a + null pointer, the conversion is performed but no output is + available. - `__GCONV_INCOMPLETE_INPUT' - The input buffer is not entirely empty since it contains an - incomplete character sequence. + If INBUF is a null pointer, the `iconv' function performs the + necessary action to put the state of the conversion into the + initial state. This is obviously a no-op for non-stateful + encodings, but if the encoding has a state, such a function call + might put some byte sequences in the output buffer, which perform + the necessary state changes. The next call with INBUF not being a + null pointer then simply goes on from the initial state. It is + important that the programmer never makes any assumption as to + whether the conversion has to deal with states. Even if the input + and output character sets are not stateful, the implementation + might still have to keep states. This is due to the + implementation chosen for the GNU C library as it is described + below. Therefore an `iconv' call to reset the state should always + be performed if some protocol requires this for the output text. - The following example provides a framework for a conversion - function. In case a new conversion has to be written the holes in - this implementation have to be filled and that is it. + The conversion stops for one of three reasons. The first is that + all characters from the input buffer are converted. This actually + can mean two things: either all bytes from the input buffer are + consumed or there are some bytes at the end of the buffer that + possibly can form a complete character but the input is + incomplete. The second reason for a stop is that the output + buffer is full. And the third reason is that the input contains + invalid characters. - int - gconv (struct __gconv_step *step, struct __gconv_step_data *data, - const char **inbuf, const char *inbufend, size_t *written, - int do_flush) - { - struct __gconv_step *next_step = step + 1; - struct __gconv_step_data *next_data = data + 1; - gconv_fct fct = next_step->__fct; - int status; - - /* If the function is called with no input this means we have - to reset to the initial state.

The user does not have to care about +stateful encodings as the functions take care of everything. - * What language to use for user answers to yes-or-no questions - (*note Yes-or-No Questions::). + An interesting point is the case where `iconv' returns an error and +`errno' is set to `EINVAL'. This is not really an error in the +transformation. It can happen whenever the input character set contains +byte sequences of more than one byte for some character and texts are +not processed in one piece. In this case there is a chance that a +multibyte sequence is cut. The caller can then simply read the +remainder of the takes and feed the offending bytes together with new +character from the input to `iconv' and continue the work. The +internal state kept in the descriptor is _not_ unspecified after such +an event as is the case with the conversion functions from the ISO C +standard. - * What language to use for more complex user input. (The C library - doesn't yet help you implement this.) + The example also shows the problem of using wide character strings +with `iconv'. As explained in the description of the `iconv' function +above, the function always takes a pointer to a `char' array and the +available space is measured in bytes. In the example, the output +buffer is a wide character buffer; therefore, we use a local variable +WRPTR of type `char *', which is used in the `iconv' calls. - Some aspects of adapting to the specified locale are handled -automatically by the library subroutines. For example, all your program -needs to do in order to use the collating sequence of the chosen locale -is to use `strcoll' or `strxfrm' to compare strings. + This looks rather innocent but can lead to problems on platforms that +have tight restriction on alignment. Therefore the caller of `iconv' +has to make sure that the pointers passed are suitable for access of +characters from the appropriate character set. Since, in the above +case, the input parameter to the function is a `wchar_t' pointer, this +is the case (unless the user violates alignment when computing the +parameter). But in other situations, especially when writing generic +functions where one does not know what type of character set one uses +and, therefore, treats text as a sequence of bytes, it might become +tricky. - Other aspects of locales are beyond the comprehension of the library. -For example, the library can't automatically translate your program's -output messages into other languages. The only way you can support -output in the user's favorite language is to program this more or less -by hand. The C library provides functions to handle translations for -multiple languages easily. + +File: libc.info, Node: Other iconv Implementations, Next: glibc iconv Implementation, Prev: iconv Examples, Up: Generic Charset Conversion - This chapter discusses the mechanism by which you can modify the -current locale. The effects of the current locale on specific library -functions are discussed in more detail in the descriptions of those -functions. +Some Details about other `iconv' Implementations +------------------------------------------------ - -File: libc.info, Node: Choosing Locale, Next: Locale Categories, Prev: Effects of Locale, Up: Locales + This is not really the place to discuss the `iconv' implementation +of other systems but it is necessary to know a bit about them to write +portable programs. The above mentioned problems with the specification +of the `iconv' functions can lead to portability issues. -Choosing a Locale -================= + The first thing to notice is that, due to the large number of +character sets in use, it is certainly not practical to encode the +conversions directly in the C library. Therefore, the conversion +information must come from files outside the C library. This is +usually done in one or both of the following ways: - The simplest way for the user to choose a locale is to set the -environment variable `LANG'. This specifies a single locale to use for -all purposes. For example, a user could specify a hypothetical locale -named `espana-castellano' to use the standard conventions of most of -Spain. + * The C library contains a set of generic conversion functions that + can read the needed conversion tables and other information from + data files. These files get loaded when necessary. - The set of locales supported depends on the operating system you are -using, and so do their names. We can't make any promises about what -locales will exist, except for one standard locale called `C' or -`POSIX'. Later we will describe how to construct locales. + This solution is problematic as it requires a great deal of effort + to apply to all character sets (potentially an infinite set). The + differences in the structure of the different character sets is so + large that many different variants of the table-processing + functions must be developed. In addition, the generic nature of + these functions make them slower than specifically implemented + functions. - A user also has the option of specifying different locales for -different purposes--in effect, choosing a mixture of multiple locales. + * The C library only contains a framework that can dynamically load + object files and execute the conversion functions contained + therein. - For example, the user might specify the locale `espana-castellano' -for most purposes, but specify the locale `usa-english' for currency -formatting. This might make sense if the user is a Spanish-speaking -American, working in Spanish, but representing monetary amounts in US -dollars. + This solution provides much more flexibility. The C library itself + contains only very little code and therefore reduces the general + memory footprint. Also, with a documented interface between the C + library and the loadable modules it is possible for third parties + to extend the set of available conversion modules. A drawback of + this solution is that dynamic loading must be available. - Note that both locales `espana-castellano' and `usa-english', like -all locales, would include conventions for all of the purposes to which -locales apply. However, the user can choose to use each locale for a -particular subset of those purposes. + Some implementations in commercial Unices implement a mixture of +these possibilities; the majority implement only the second solution. +Using loadable modules moves the code out of the library itself and +keeps the door open for extensions and improvements, but this design is +also limiting on some platforms since not many platforms support dynamic +loading in statically linked programs. On platforms without this +capability it is therefore not possible to use this interface in +statically linked programs. The GNU C library has, on ELF platforms, no +problems with dynamic loading in these situations; therefore, this +point is moot. The danger is that one gets acquainted with this +situation and forgets about the restrictions on other systems. - -File: libc.info, Node: Locale Categories, Next: Setting the Locale, Prev: Choosing Locale, Up: Locales + A second thing to know about other `iconv' implementations is that +the number of available conversions is often very limited. Some +implementations provide, in the standard release (not special +international or developer releases), at most 100 to 200 conversion +possibilities. This does not mean 200 different character sets are +supported; for example, conversions from one character set to a set of +10 others might count as 10 conversions. Together with the other +direction this makes 20 conversion possibilities used up by one +character set. One can imagine the thin coverage these platform +provide. Some Unix vendors even provide only a handful of conversions, +which renders them useless for almost all uses. -Categories of Activities that Locales Affect -============================================ + This directly leads to a third and probably the most problematic +point. The way the `iconv' conversion functions are implemented on all +known Unix systems and the availability of the conversion functions from +character set A to B and the conversion from B to C does _not_ imply +that the conversion from A to C is available. - The purposes that locales serve are grouped into "categories", so -that a user or a program can choose the locale for each category -independently. Here is a table of categories; each name is both an -environment variable that a user can set, and a macro name that you can -use as an argument to `setlocale'. + This might not seem unreasonable and problematic at first, but it is +a quite big problem as one will notice shortly after hitting it. To +show the problem we assume to write a program that has to convert from +A to C. A call like -`LC_COLLATE' - This category applies to collation of strings (functions `strcoll' - and `strxfrm'); see *Note Collation Functions::. + cd = iconv_open ("C", "A"); -`LC_CTYPE' - This category applies to classification and conversion of - characters, and to multibyte and wide characters; see *Note - Character Handling::, and *Note Character Set Handling::. +fails according to the assumption above. But what does the program do +now? The conversion is necessary; therefore, simply giving up is not +an option. -`LC_MONETARY' - This category applies to formatting monetary values; see *Note - General Numeric::. + This is a nuisance. The `iconv' function should take care of this. +But how should the program proceed from here on? If it tries to convert +to character set B, first the two `iconv_open' calls -`LC_NUMERIC' - This category applies to formatting numeric values that are not - monetary; see *Note General Numeric::. + cd1 = iconv_open ("B", "A"); -`LC_TIME' - This category applies to formatting date and time values; see - *Note Formatting Calendar Time::. +and -`LC_MESSAGES' - This category applies to selecting the language used in the user - interface for message translation (*note The Uniforum approach::; - *note Message catalogs a la X/Open::) and contains regular - expressions for affirmative and negative responses. + cd2 = iconv_open ("C", "B"); -`LC_ALL' - This is not an environment variable; it is only a macro that you - can use with `setlocale' to set a single locale for all purposes. - Setting this environment variable overwrites all selections by the - other `LC_*' variables or `LANG'. +will succeed, but how to find B? -`LANG' - If this environment variable is defined, its value specifies the - locale to use for all purposes except as overridden by the - variables above. + Unfortunately, the answer is: there is no general solution. On some +systems guessing might help. On those systems most character sets can +convert to and from UTF-8 encoded ISO 10646 or Unicode text. Beside +this only some very system-specific methods can help. Since the +conversion functions come from loadable modules and these modules must +be stored somewhere in the filesystem, one _could_ try to find them and +determine from the available file which conversions are available and +whether there is an indirect route from A to C. - When developing the message translation functions it was felt that -the functionality provided by the variables above is not sufficient. -For example, it should be possible to specify more than one locale name. -Take a Swedish user who better speaks German than English, and a program -whose messages are output in English by default. It should be possible -to specify that the first choice of language is Swedish, the second -German, and if this also fails to use English. This is possible with -the variable `LANGUAGE'. For further description of this GNU extension -see *Note Using gettextized software::. + This example shows one of the design errors of `iconv' mentioned +above. It should at least be possible to determine the list of +available conversion programmatically so that if `iconv_open' says +there is no such conversion, one could make sure this also is true for +indirect routes. diff -durpN glibc-2.2.4/manual/libc.info-11 glibc-2.2.5/manual/libc.info-11 --- glibc-2.2.4/manual/libc.info-11 Mon Aug 13 15:03:42 2001 +++ glibc-2.2.5/manual/libc.info-11 Sun Jan 20 19:28:42 2002 @@ -1,4 +1,4 @@ -This is libc.info, produced by makeinfo version 4.0c from libc.texinfo. +This is libc.info, produced by makeinfo version 4.0 from libc.texinfo.

For these cases it is necessary to access the -information in the locale directly. To do this the C library provides -two functions: `localeconv' and `nl_langinfo'.

This value specifies no grouping at all. + After reading about the problems of `iconv' implementations in the +last section it is certainly good to note that the implementation in +the GNU C library has none of the problems mentioned above. What +follows is a step-by-step analysis of the points raised above. The +evaluation is based on the current state of the development (as of +January 1999). The development of the `iconv' functions is not +complete, but basic functionality has solidified. -`char int_frac_digits' -`char frac_digits' - These are small integers indicating how many fractional digits (to - the right of the decimal point) should be displayed in a monetary - value in international and local formats, respectively. (Most - often, both members have the same value.) + The GNU C library's `iconv' implementation uses shared loadable +modules to implement the conversions. A very small number of +conversions are built into the library itself but these are only rather +trivial conversions. - In the standard `C' locale, both of these members have the value - `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say - what to do when you find this value; we recommend printing no - fractional digits. (This locale also specifies the empty string - for `mon_decimal_point', so printing any fractional digits would be - confusing!) + All the benefits of loadable modules are available in the GNU C +library implementation. This is especially appealing since the +interface is well documented (see below), and it, therefore, is easy to +write new conversion modules. The drawback of using loadable objects +is not a problem in the GNU C library, at least on ELF systems. Since +the library is able to load shared objects even in statically linked +binaries, static linking need not be forbidden in case one wants to use +`iconv'. - -File: libc.info, Node: Currency Symbol, Next: Sign of Money Amount, Prev: General Numeric, Up: The Lame Way to Locale Data + The second mentioned problem is the number of supported conversions. +Currently, the GNU C library supports more than 150 character sets. The +way the implementation is designed the number of supported conversions +is greater than 22350 (150 times 149). If any conversion from or to a +character set is missing, it can be added easily. -Printing the Currency Symbol -............................ + Particularly impressive as it may be, this high number is due to the +fact that the GNU C library implementation of `iconv' does not have the +third problem mentioned above (i.e., whenever there is a conversion +from a character set A to B and from B to C it is always possible to +convert from A to C directly). If the `iconv_open' returns an error +and sets `errno' to `EINVAL', there is no known way, directly or +indirectly, to perform the wanted conversion. - These members of the `struct lconv' structure specify how to print -the symbol to identify a monetary value--the international analog of -`$' for US dollars. + Triangulation is achieved by providing for each character set a +conversion from and to UCS-4 encoded ISO 10646. Using ISO 10646 as an +intermediate representation it is possible to "triangulate" (i.e., +convert with an intermediate representation). - Each country has two standard currency symbols. The "local currency -symbol" is used commonly within the country, while the "international -currency symbol" is used internationally to refer to that country's -currency when it is necessary to indicate the country unambiguously. + There is no inherent requirement to provide a conversion to +ISO 10646 for a new character set, and it is also possible to provide +other conversions where neither source nor destination character set is +ISO 10646. The existing set of conversions is simply meant to cover all +conversions that might be of interest. - For example, many countries use the dollar as their monetary unit, -and when dealing with international currencies it's important to specify -that one is dealing with (say) Canadian dollars instead of U.S. dollars -or Australian dollars. But when the context is known to be Canada, -there is no need to make this explicit--dollar amounts are implicitly -assumed to be in Canadian dollars. + All currently available conversions use the triangulation method +above, making conversion run unnecessarily slow. If, for example, +somebody often needs the conversion from ISO-2022-JP to EUC-JP, a +quicker solution would involve direct conversion between the two +character sets, skipping the input to ISO 10646 first. The two +character sets of interest are much more similar to each other than to +ISO 10646. -`char *currency_symbol' - The local currency symbol for the selected locale. + In such a situation one easily can write a new conversion and +provide it as a better alternative. The GNU C library `iconv' +implementation would automatically use the module implementing the +conversion if it is specified to be more efficient. - In the standard `C' locale, this member has a value of `""' (the - empty string), meaning "unspecified". The ISO standard doesn't - say what to do when you find this value; we recommend you simply - print the empty string as you would print any other string pointed - to by this variable. +Format of `gconv-modules' files +............................... -`char *int_curr_symbol' - The international currency symbol for the selected locale. + All information about the available conversions comes from a file +named `gconv-modules', which can be found in any of the directories +along the `GCONV_PATH'. The `gconv-modules' files are line-oriented +text files, where each of the lines has one of the following formats: - The value of `int_curr_symbol' should normally consist of a - three-letter abbreviation determined by the international standard - `ISO 4217 Codes for the Representation of Currency and Funds', - followed by a one-character separator (often a space). + * If the first non-whitespace character is a `#' the line contains + only comments and is ignored. - In the standard `C' locale, this member has a value of `""' (the - empty string), meaning "unspecified". We recommend you simply - print the empty string as you would print any other string pointed - to by this variable. + * Lines starting with `alias' define an alias name for a character + set. Two more words are expected on the line. The first word + defines the alias name, and the second defines the original name + of the character set. The effect is that it is possible to use + the alias name in the FROMSET or TOSET parameters of `iconv_open' + and achieve the same result as when using the real character set + name. -`char p_cs_precedes' -`char n_cs_precedes' -`char int_p_cs_precedes' -`char int_n_cs_precedes' - These members are `1' if the `currency_symbol' or - `int_curr_symbol' strings should precede the value of a monetary - amount, or `0' if the strings should follow the value. The - `p_cs_precedes' and `int_p_cs_precedes' members apply to positive - amounts (or zero), and the `n_cs_precedes' and `int_n_cs_precedes' - members apply to negative amounts. + This is quite important as a character set has often many different + names. There is normally an official name but this need not + correspond to the most popular name. Beside this many character + sets have special names that are somehow constructed. For + example, all character sets specified by the ISO have an alias of + the form `ISO-IR-NNN' where NNN is the registration number. This + allows programs that know about the registration number to + construct character set names and use them in `iconv_open' calls. + More on the available names and aliases follows below. - In the standard `C' locale, all of these members have a value of - `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say - what to do when you find this value. We recommend printing the - currency symbol before the amount, which is right for most - countries. In other words, treat all nonzero values alike in - these members. + * Lines starting with `module' introduce an available conversion + module. These lines must contain three or four more words. - The members with the `int_' prefix apply to the `int_curr_symbol' - while the other two apply to `currency_symbol'. + The first word specifies the source character set, the second word + the destination character set of conversion implemented in this + module, and the third word is the name of the loadable module. + The filename is constructed by appending the usual shared object + suffix (normally `.so') and this file is then supposed to be found + in the same directory the `gconv-modules' file is in. The last + word on the line, which is optional, is a numeric value + representing the cost of the conversion. If this word is missing, + a cost of 1 is assumed. The numeric value itself does not matter + that much; what counts are the relative values of the sums of + costs for all possible conversion paths. Below is a more precise + description of the use of the cost value. -`char p_sep_by_space' -`char n_sep_by_space' -`char int_p_sep_by_space' -`char int_n_sep_by_space' - These members are `1' if a space should appear between the - `currency_symbol' or `int_curr_symbol' strings and the amount, or - `0' if no space should appear. The `p_sep_by_space' and - `int_p_sep_by_space' members apply to positive amounts (or zero), - and the `n_sep_by_space' and `int_n_sep_by_space' members apply to - negative amounts. + Returning to the example above where one has written a module to +directly convert from ISO-2022-JP to EUC-JP and back. All that has to +be done is to put the new module, let its name be ISO2022JP-EUCJP.so, +in a directory and add a file `gconv-modules' with the following +content in the same directory: - In the standard `C' locale, all of these members have a value of - `CHAR_MAX', meaning "unspecified". The ISO standard doesn't say - what you should do when you find this value; we suggest you treat - it as 1 (print a space). In other words, treat all nonzero values - alike in these members. + module ISO-2022-JP// EUC-JP// ISO2022JP-EUCJP 1 + module EUC-JP// ISO-2022-JP// ISO2022JP-EUCJP 1 - The members with the `int_' prefix apply to the `int_curr_symbol' - while the other two apply to `currency_symbol'. There is one - specialty with the `int_curr_symbol', though. Since all legal - values contain a space at the end the string one either printf - this space (if the currency symbol must appear in front and must - be separated) or one has to avoid printing this character at all - (especially when at the end of the string). + To see why this is sufficient, it is necessary to understand how the +conversion used by `iconv' (and described in the descriptor) is +selected. The approach to this problem is quite simple. - -File: libc.info, Node: Sign of Money Amount, Prev: Currency Symbol, Up: The Lame Way to Locale Data + At the first call of the `iconv_open' function the program reads all +available `gconv-modules' files and builds up two tables: one +containing all the known aliases and another that contains the +information about the conversions and which shared object implements +them. -Printing the Sign of a Monetary Amount +Finding the conversion path in `iconv' ...................................... - These members of the `struct lconv' structure specify how to print -the sign (if any) of a monetary value. - -`char *positive_sign' -`char *negative_sign' - These are strings used to indicate positive (or zero) and negative - monetary quantities, respectively. - - In the standard `C' locale, both of these members have a value of - `""' (the empty string), meaning "unspecified". + The set of available conversions form a directed graph with weighted +edges. The weights on the edges are the costs specified in the +`gconv-modules' files. The `iconv_open' function uses an algorithm +suitable for search for the best path in such a graph and so constructs +a list of conversions that must be performed in succession to get the +transformation from the source to the destination character set. - The ISO standard doesn't say what to do when you find this value; - we recommend printing `positive_sign' as you find it, even if it is - empty. For a negative value, print `negative_sign' as you find it - unless both it and `positive_sign' are empty, in which case print - `-' instead. (Failing to indicate the sign at all seems rather - unreasonable.) + Explaining why the above `gconv-modules' files allows the `iconv' +implementation to resolve the specific ISO-2022-JP to EUC-JP conversion +module instead of the conversion coming with the library itself is +straightforward. Since the latter conversion takes two steps (from +ISO-2022-JP to ISO 10646 and then from ISO 10646 to EUC-JP), the cost +is 1+1 = 2. The above `gconv-modules' file, however, specifies that +the new conversion modules can perform this conversion with only the +cost of 1. -`char p_sign_posn' -`char n_sign_posn' -`char int_p_sign_posn' -`char int_n_sign_posn' - These members are small integers that indicate how to position the - sign for nonnegative and negative monetary quantities, - respectively. (The string used by the sign is what was specified - with `positive_sign' or `negative_sign'.) The possible values are - as follows: + A mysterious item about the `gconv-modules' file above (and also the +file coming with the GNU C library) are the names of the character sets +specified in the `module' lines. Why do almost all the names end in +`//'? And this is not all: the names can actually be regular +expressions. At this point in time this mystery should not be +revealed, unless you have the relevant spell-casting materials: ashes +from an original DOS 6.2 boot disk burnt in effigy, a crucifix blessed +by St. Emacs, assorted herbal roots from Central America, sand from +Cebu, etc. Sorry! *The part of the implementation where this is used +is not yet finished. For now please simply follow the existing +examples. It'll become clearer once it is. -drepper* - `0' - The currency symbol and quantity should be surrounded by - parentheses. + A last remark about the `gconv-modules' is about the names not +ending with `//'. A character set named `INTERNAL' is often mentioned. +From the discussion above and the chosen name it should have become +clear that this is the name for the representation used in the +intermediate step of the triangulation. We have said that this is UCS-4 +but actually that is not quite right. The UCS-4 specification also +includes the specification of the byte ordering used. Since a UCS-4 +value consists of four bytes, a stored value is effected by byte +ordering. The internal representation is _not_ the same as UCS-4 in +case the byte ordering of the processor (or at least the running +process) is not the same as the one required for UCS-4. This is done +for performance reasons as one does not want to perform unnecessary +byte-swapping operations if one is not interested in actually seeing +the result in UCS-4. To avoid trouble with endianess, the internal +representation consistently is named `INTERNAL' even on big-endian +systems where the representations are identical. - `1' - Print the sign string before the quantity and currency symbol. +`iconv' module data structures +.............................. - `2' - Print the sign string after the quantity and currency symbol. + So far this section has described how modules are located and +considered to be used. What remains to be described is the interface +of the modules so that one can write new ones. This section describes +the interface as it is in use in January 1999. The interface will +change a bit in the future but, with luck, only in an upwardly +compatible way. - `3' - Print the sign string right before the currency symbol. + The definitions necessary to write new modules are publicly available +in the non-standard header `gconv.h'. The following text, therefore, +describes the definitions from this header file. First, however, it is +necessary to get an overview. - `4' - Print the sign string right after the currency symbol. + From the perspective of the user of `iconv' the interface is quite +simple: the `iconv_open' function returns a handle that can be used in +calls to `iconv', and finally the handle is freed with a call to +`iconv_close'. The problem is that the handle has to be able to +represent the possibly long sequences of conversion steps and also the +state of each conversion since the handle is all that is passed to the +`iconv' function. Therefore, the data structures are really the +elements necessary to understanding the implementation. - `CHAR_MAX' - "Unspecified". Both members have this value in the standard - `C' locale. + We need two different kinds of data structures. The first describes +the conversion and the second describes the state etc. There are +really two type definitions like this in `gconv.h'. - The ISO standard doesn't say what you should do when the value is - `CHAR_MAX'. We recommend you print the sign after the currency - symbol. + - Data type: struct __gconv_step + This data structure describes one conversion a module can perform. + For each function in a loaded module with conversion functions + there is exactly one object of this type. This object is shared + by all users of the conversion (i.e., this object does not contain + any information corresponding to an actual conversion; it only + describes the conversion itself). - The members with the `int_' prefix apply to the `int_curr_symbol' - while the other two apply to `currency_symbol'. + `struct __gconv_loaded_object *__shlib_handle' + `const char *__modname' + `int __counter' + All these elements of the structure are used internally in + the C library to coordinate loading and unloading the shared. + One must not expect any of the other elements to be + available or initialized. - -File: libc.info, Node: The Elegant and Fast Way, Prev: The Lame Way to Locale Data, Up: Locale Information + `const char *__from_name' + `const char *__to_name' + `__from_name' and `__to_name' contain the names of the source + and destination character sets. They can be used to identify + the actual conversion to be carried out since one module + might implement conversions for more than one character set + and/or direction. -Pinpoint Access to Locale Data ------------------------------- + `gconv_fct __fct' + `gconv_init_fct __init_fct' + `gconv_end_fct __end_fct' + These elements contain pointers to the functions in the + loadable module. The interface will be explained below. - When writing the X/Open Portability Guide the authors realized that -the `localeconv' function is not enough to provide reasonable access to -locale information. The information which was meant to be available in -the locale (as later specified in the POSIX.1 standard) requires more -ways to access it. Therefore the `nl_langinfo' function was introduced. + `int __min_needed_from' + `int __max_needed_from' + `int __min_needed_to' + `int __max_needed_to;' + These values have to be supplied in the init function of the + module. The `__min_needed_from' value specifies how many + bytes a character of the source character set at least needs. + The `__max_needed_from' specifies the maximum value that + also includes possible shift sequences. - - Function: char * nl_langinfo (nl_item ITEM) - The `nl_langinfo' function can be used to access individual - elements of the locale categories. Unlike the `localeconv' - function, which returns all the information, `nl_langinfo' lets - the caller select what information it requires. This is very fast - and it is not a problem to call this function multiple times. + The `__min_needed_to' and `__max_needed_to' values serve the + same purpose as `__min_needed_from' and `__max_needed_from' + but this time for the destination character set. - A second advantage is that in addition to the numeric and monetary - formatting information, information from the `LC_TIME' and - `LC_MESSAGES' categories is available. + It is crucial that these values be accurate since otherwise + the conversion functions will have problems or not work at + all. - The type `nl_type' is defined in `nl_types.h'. The argument ITEM - is a numeric value defined in the header `langinfo.h'. The X/Open - standard defines the following values: + `int __stateful' + This element must also be initialized by the init function. + `int __stateful' is nonzero if the source character set is + stateful. Otherwise it is zero. - `CODESET' - `nl_langinfo' returns a string with the name of the coded - character set used in the selected locale. + `void *__data' + This element can be used freely by the conversion functions + in the module. `void *__data' can be used to communicate + extra information from one call to another. `void *__data' + need not be initialized if not needed at all. If `void + *__data' element is assigned a pointer to dynamically + allocated memory (presumably in the init function) it has to + be made sure that the end function deallocates the memory. + Otherwise the application will leak memory. - `ABDAY_1' - `ABDAY_2' - `ABDAY_3' - `ABDAY_4' - `ABDAY_5' - `ABDAY_6' - `ABDAY_7' - `nl_langinfo' returns the abbreviated weekday name. `ABDAY_1' - corresponds to Sunday. + It is important to be aware that this data structure is + shared by all users of this specification conversion and + therefore the `__data' element must not contain data specific + to one specific use of the conversion function. - `DAY_1' - `DAY_2' - `DAY_3' - `DAY_4' - `DAY_5' - `DAY_6' - `DAY_7' - Similar to `ABDAY_1' etc., but here the return value is the - unabbreviated weekday name. + - Data type: struct __gconv_step_data + This is the data structure that contains the information specific + to each use of the conversion functions. - `ABMON_1' - `ABMON_2' - `ABMON_3' - `ABMON_4' - `ABMON_5' - `ABMON_6' - `ABMON_7' - `ABMON_8' - `ABMON_9' - `ABMON_10' - `ABMON_11' - `ABMON_12' - The return value is abbreviated name of the month. `ABMON_1' - corresponds to January. + `char *__outbuf' + `char *__outbufend' + These elements specify the output buffer for the conversion + step. The `__outbuf' element points to the beginning of the + buffer, and `__outbufend' points to the byte following the + last byte in the buffer. The conversion function must not + assume anything about the size of the buffer but it can be + safely assumed the there is room for at least one complete + character in the output buffer. - `MON_1' - `MON_2' - `MON_3' - `MON_4' - `MON_5' - `MON_6' - `MON_7' - `MON_8' - `MON_9' - `MON_10' - `MON_11' - `MON_12' - Similar to `ABMON_1' etc., but here the month names are not - abbreviated. Here the first value `MON_1' also corresponds - to January. + Once the conversion is finished, if the conversion is the + last step, the `__outbuf' element must be modified to point + after the last byte written into the buffer to signal how + much output is available. If this conversion step is not the + last one, the element must not be modified. The + `__outbufend' element must not be modified. - `AM_STR' - `PM_STR' - The return values are strings which can be used in the - representation of time as an hour from 1 to 12 plus an am/pm - specifier. + `int __is_last' + This element is nonzero if this conversion step is the last + one. This information is necessary for the recursion. See + the description of the conversion function internals below. + This element must never be modified. - Note that in locales which do not use this time representation - these strings might be empty, in which case the am/pm format - cannot be used at all. + `int __invocation_counter' + The conversion function can use this element to see how many + calls of the conversion function already happened. Some + character sets require a certain prolog when generating + output, and by comparing this value with zero, one can find + out whether it is the first call and whether, therefore, the + prolog should be emitted. This element must never be + modified. - `D_T_FMT' - The return value can be used as a format string for - `strftime' to represent time and date in a locale-specific - way. + `int __internal_use' + This element is another one rarely used but needed in certain + situations. It is assigned a nonzero value in case the + conversion functions are used to implement `mbsrtowcs' et.al. + (i.e., the function is not used directly through the `iconv' + interface). - `D_FMT' - The return value can be used as a format string for - `strftime' to represent a date in a locale-specific way. + This sometimes makes a difference as it is expected that the + `iconv' functions are used to translate entire texts while the + `mbsrtowcs' functions are normally used only to convert single + strings and might be used multiple times to convert entire + texts. - `T_FMT' - The return value can be used as a format string for - `strftime' to represent time in a locale-specific way. + But in this situation we would have problem complying with + some rules of the character set specification. Some + character sets require a prolog, which must appear exactly + once for an entire text. If a number of `mbsrtowcs' calls + are used to convert the text, only the first call must add + the prolog. However, because there is no communication + between the different calls of `mbsrtowcs', the conversion + functions have no possibility to find this out. The + situation is different for sequences of `iconv' calls since + the handle allows access to the needed information. - `T_FMT_AMPM' - The return value can be used as a format string for - `strftime' to represent time in the am/pm format. + The `int __internal_use' element is mostly used together with + `__invocation_counter' as follows: - Note that if the am/pm format does not make any sense for the - selected locale, the return value might be the same as the - one for `T_FMT'. + if (!data->__internal_use + && data->__invocation_counter == 0) + /* Emit prolog. */ + ... - `ERA' - The return value represents the era used in the current - locale. + This element must never be modified. - Most locales do not define this value. An example of a - locale which does define this value is the Japanese one. In - Japan, the traditional representation of dates includes the - name of the era corresponding to the then-emperor's reign. + `mbstate_t *__statep' + The `__statep' element points to an object of type `mbstate_t' + (*note Keeping the state::). The conversion of a stateful + character set must use the object pointed to by `__statep' to + store information about the conversion state. The `__statep' + element itself must never be modified. - Normally it should not be necessary to use this value - directly. Specifying the `E' modifier in their format - strings causes the `strftime' functions to use this - information. The format of the returned string is not - specified, and therefore you should not assume knowledge of - it on different systems. + `mbstate_t __state' + This element must _never_ be used directly. It is only part + of this structure to have the needed space allocated. - `ERA_YEAR' - The return value gives the year in the relevant era of the - locale. As for `ERA' it should not be necessary to use this - value directly. +`iconv' module interfaces +......................... - `ERA_D_T_FMT' - This return value can be used as a format string for - `strftime' to represent dates and times in a locale-specific - era-based way. + With the knowledge about the data structures we now can describe the +conversion function itself. To understand the interface a bit of +knowledge is necessary about the functionality in the C library that +loads the objects with the conversions. - `ERA_D_FMT' - This return value can be used as a format string for - `strftime' to represent a date in a locale-specific era-based - way. + It is often the case that one conversion is used more than once +(i.e., there are several `iconv_open' calls for the same set of +character sets during one program run). The `mbsrtowcs' et.al. +functions in the GNU C library also use the `iconv' functionality, which +increases the number of uses of the same functions even more. - `ERA_T_FMT' - This return value can be used as a format string for - `strftime' to represent time in a locale-specific era-based - way. + Because of this multiple use of conversions, the modules do not get +loaded exclusively for one conversion. Instead a module once loaded can +be used by an arbitrary number of `iconv' or `mbsrtowcs' calls at the +same time. The splitting of the information between conversion- +function-specific information and conversion data makes this possible. +The last section showed the two data structures used to do this. - `ALT_DIGITS' - The return value is a representation of up to 100 values used - to represent the values 0 to 99. As for `ERA' this value is - not intended to be used directly, but instead indirectly - through the `strftime' function. When the modifier `O' is - used in a format which would otherwise use numerals to - represent hours, minutes, seconds, weekdays, months, or - weeks, the appropriate value for the locale is used instead. + This is of course also reflected in the interface and semantics of +the functions that the modules must provide. There are three functions +that must have the following names: - `INT_CURR_SYMBOL' - The same as the value returned by `localeconv' in the - `int_curr_symbol' element of the `struct lconv'. +`gconv_init' + The `gconv_init' function initializes the conversion function + specific data structure. This very same object is shared by all + conversions that use this conversion and, therefore, no state + information about the conversion itself must be stored in here. + If a module implements more than one conversion, the `gconv_init' + function will be called multiple times. - `CURRENCY_SYMBOL' - `CRNCYSTR' - The same as the value returned by `localeconv' in the - `currency_symbol' element of the `struct lconv'. +`gconv_end' + The `gconv_end' function is responsible for freeing all resources + allocated by the `gconv_init' function. If there is nothing to do, + this function can be missing. Special care must be taken if the + module implements more than one conversion and the `gconv_init' + function does not allocate the same resources for all conversions. - `CRNCYSTR' is a deprecated alias still required by Unix98. +`gconv' + This is the actual conversion function. It is called to convert + one block of text. It gets passed the conversion step information + initialized by `gconv_init' and the conversion data, specific to + this use of the conversion functions. - `MON_DECIMAL_POINT' - The same as the value returned by `localeconv' in the - `mon_decimal_point' element of the `struct lconv'. + There are three data types defined for the three module interface +functions and these define the interface. - `MON_THOUSANDS_SEP' - The same as the value returned by `localeconv' in the - `mon_thousands_sep' element of the `struct lconv'. + - Data type: int (*__gconv_init_fct) (struct __gconv_step *) + This specifies the interface of the initialization function of the + module. It is called exactly once for each conversion the module + implements. - `MON_GROUPING' - The same as the value returned by `localeconv' in the - `mon_grouping' element of the `struct lconv'. + As explained in the description of the `struct __gconv_step' data + structure above the initialization function has to initialize + parts of it. - `POSITIVE_SIGN' - The same as the value returned by `localeconv' in the - `positive_sign' element of the `struct lconv'. + `__min_needed_from' + `__max_needed_from' + `__min_needed_to' + `__max_needed_to' + These elements must be initialized to the exact numbers of + the minimum and maximum number of bytes used by one character + in the source and destination character sets, respectively. + If the characters all have the same size, the minimum and + maximum values are the same. - `NEGATIVE_SIGN' - The same as the value returned by `localeconv' in the - `negative_sign' element of the `struct lconv'. + `__stateful' + This element must be initialized to an nonzero value if the + source character set is stateful. Otherwise it must be zero. - `INT_FRAC_DIGITS' - The same as the value returned by `localeconv' in the - `int_frac_digits' element of the `struct lconv'. + If the initialization function needs to communicate some + information to the conversion function, this communication can + happen using the `__data' element of the `__gconv_step' structure. + But since this data is shared by all the conversions, it must not + be modified by the conversion function. The example below shows + how this can be used. - `FRAC_DIGITS' - The same as the value returned by `localeconv' in the - `frac_digits' element of the `struct lconv'. + #define MIN_NEEDED_FROM 1 + #define MAX_NEEDED_FROM 4 + #define MIN_NEEDED_TO 4 + #define MAX_NEEDED_TO 4 + + int + gconv_init (struct __gconv_step *step) + { + /* Determine which direction. */ + struct iso2022jp_data *new_data; + enum direction dir = illegal_dir; + enum variant var = illegal_var; + int result; + + if (__strcasecmp (step->__from_name, "ISO-2022-JP//") == 0) + { + dir = from_iso2022jp; + var = iso2022jp; + } + else if (__strcasecmp (step->__to_name, "ISO-2022-JP//") == 0) + { + dir = to_iso2022jp; + var = iso2022jp; + } + else if (__strcasecmp (step->__from_name, "ISO-2022-JP-2//") == 0) + { + dir = from_iso2022jp; + var = iso2022jp2; + } + else if (__strcasecmp (step->__to_name, "ISO-2022-JP-2//") == 0) + { + dir = to_iso2022jp; + var = iso2022jp2; + } + + result = __GCONV_NOCONV; + if (dir != illegal_dir) + { + new_data = (struct iso2022jp_data *) + malloc (sizeof (struct iso2022jp_data)); + + result = __GCONV_NOMEM; + if (new_data != NULL) + { + new_data->dir = dir; + new_data->var = var; + step->__data = new_data; + + if (dir == from_iso2022jp) + { + step->__min_needed_from = MIN_NEEDED_FROM; + step->__max_needed_from = MAX_NEEDED_FROM; + step->__min_needed_to = MIN_NEEDED_TO; + step->__max_needed_to = MAX_NEEDED_TO; + } + else + { + step->__min_needed_from = MIN_NEEDED_TO; + step->__max_needed_from = MAX_NEEDED_TO; + step->__min_needed_to = MIN_NEEDED_FROM; + step->__max_needed_to = MAX_NEEDED_FROM + 2; + } + + /* Yes, this is a stateful encoding. */ + step->__stateful = 1; + + result = __GCONV_OK; + } + } + + return result; + } - `P_CS_PRECEDES' - The same as the value returned by `localeconv' in the - `p_cs_precedes' element of the `struct lconv'. + The function first checks which conversion is wanted. The module + from which this function is taken implements four different + conversions; which one is selected can be determined by comparing + the names. The comparison should always be done without paying + attention to the case. - `P_SEP_BY_SPACE' - The same as the value returned by `localeconv' in the - `p_sep_by_space' element of the `struct lconv'. + Next, a data structure, which contains the necessary information + about which conversion is selected, is allocated. The data + structure `struct iso2022jp_data' is locally defined since, + outside the module, this data is not used at all. Please note + that if all four conversions this modules supports are requested + there are four data blocks. - `N_CS_PRECEDES' - The same as the value returned by `localeconv' in the - `n_cs_precedes' element of the `struct lconv'. + One interesting thing is the initialization of the `__min_' and + `__max_' elements of the step data object. A single ISO-2022-JP + character can consist of one to four bytes. Therefore the + `MIN_NEEDED_FROM' and `MAX_NEEDED_FROM' macros are defined this + way. The output is always the `INTERNAL' character set (aka + UCS-4) and therefore each character consists of exactly four + bytes. For the conversion from `INTERNAL' to ISO-2022-JP we have + to take into account that escape sequences might be necessary to + switch the character sets. Therefore the `__max_needed_to' + element for this direction gets assigned `MAX_NEEDED_FROM + 2'. + This takes into account the two bytes needed for the escape + sequences to single the switching. The asymmetry in the maximum + values for the two directions can be explained easily: when + reading ISO-2022-JP text, escape sequences can be handled alone + (i.e., it is not necessary to process a real character since the + effect of the escape sequence can be recorded in the state + information). The situation is different for the other direction. + Since it is in general not known which character comes next, one + cannot emit escape sequences to change the state in advance. This + means the escape sequences that have to be emitted together with + the next character. Therefore one needs more room than only for + the character itself. - `N_SEP_BY_SPACE' - The same as the value returned by `localeconv' in the - `n_sep_by_space' element of the `struct lconv'. + The possible return values of the initialization function are: - `P_SIGN_POSN' - The same as the value returned by `localeconv' in the - `p_sign_posn' element of the `struct lconv'. + `__GCONV_OK' + The initialization succeeded - `N_SIGN_POSN' - The same as the value returned by `localeconv' in the - `n_sign_posn' element of the `struct lconv'. + `__GCONV_NOCONV' + The requested conversion is not supported in the module. + This can happen if the `gconv-modules' file has errors. - `INT_P_CS_PRECEDES' - The same as the value returned by `localeconv' in the - `int_p_cs_precedes' element of the `struct lconv'. + `__GCONV_NOMEM' + Memory required to store additional information could not be + allocated. - `INT_P_SEP_BY_SPACE' - The same as the value returned by `localeconv' in the - `int_p_sep_by_space' element of the `struct lconv'. + The function called before the module is unloaded is significantly +easier. It often has nothing at all to do; in which case it can be left +out completely. - `INT_N_CS_PRECEDES' - The same as the value returned by `localeconv' in the - `int_n_cs_precedes' element of the `struct lconv'. + - Data type: void (*__gconv_end_fct) (struct gconv_step *) + The task of this function is to free all resources allocated in the + initialization function. Therefore only the `__data' element of + the object pointed to by the argument is of interest. Continuing + the example from the initialization function, the finalization + function looks like this: - `INT_N_SEP_BY_SPACE' - The same as the value returned by `localeconv' in the - `int_n_sep_by_space' element of the `struct lconv'. + void + gconv_end (struct __gconv_step *data) + { + free (data->__data); + } - `INT_P_SIGN_POSN' - The same as the value returned by `localeconv' in the - `int_p_sign_posn' element of the `struct lconv'. + The most important function is the conversion function itself, which +can get quite complicated for complex character sets. But since this +is not of interest here, we will only describe a possible skeleton for +the conversion function. - `INT_N_SIGN_POSN' - The same as the value returned by `localeconv' in the - `int_n_sign_posn' element of the `struct lconv'. + - Data type: int (*__gconv_fct) (struct __gconv_step *, struct + __gconv_step_data *, const char **, const char *, size_t *, + int) + The conversion function can be called for two basic reason: to + convert text or to reset the state. From the description of the + `iconv' function it can be seen why the flushing mode is + necessary. What mode is selected is determined by the sixth + argument, an integer. This argument being nonzero means that + flushing is selected. - `DECIMAL_POINT' - `RADIXCHAR' - The same as the value returned by `localeconv' in the - `decimal_point' element of the `struct lconv'. + Common to both modes is where the output buffer can be found. The + information about this buffer is stored in the conversion step + data. A pointer to this information is passed as the second + argument to this function. The description of the `struct + __gconv_step_data' structure has more information on the + conversion step data. - The name `RADIXCHAR' is a deprecated alias still used in - Unix98. + What has to be done for flushing depends on the source character + set. If the source character set is not stateful, nothing has to + be done. Otherwise the function has to emit a byte sequence to + bring the state object into the initial state. Once this all + happened the other conversion modules in the chain of conversions + have to get the same chance. Whether another step follows can be + determined from the `__is_last' element of the step data structure + to which the first parameter points. - `THOUSANDS_SEP' - `THOUSEP' - The same as the value returned by `localeconv' in the - `thousands_sep' element of the `struct lconv'. + The more interesting mode is when actual text has to be converted. + The first step in this case is to convert as much text as + possible from the input buffer and store the result in the output + buffer. The start of the input buffer is determined by the third + argument, which is a pointer to a pointer variable referencing the + beginning of the buffer. The fourth argument is a pointer to the + byte right after the last byte in the buffer. - The name `THOUSEP' is a deprecated alias still used in Unix98. + The conversion has to be performed according to the current state + if the character set is stateful. The state is stored in an + object pointed to by the `__statep' element of the step data + (second argument). Once either the input buffer is empty or the + output buffer is full the conversion stops. At this point, the + pointer variable referenced by the third parameter must point to + the byte following the last processed byte (i.e., if all of the + input is consumed, this pointer and the fourth parameter have the + same value). - `GROUPING' - The same as the value returned by `localeconv' in the - `grouping' element of the `struct lconv'. + What now happens depends on whether this step is the last one. If + it is the last step, the only thing that has to be done is to + update the `__outbuf' element of the step data structure to point + after the last written byte. This update gives the caller the + information on how much text is available in the output buffer. + In addition, the variable pointed to by the fifth parameter, which + is of type `size_t', must be incremented by the number of + characters (_not bytes_) that were converted in a non-reversible + way. Then, the function can return. - `YESEXPR' - The return value is a regular expression which can be used - with the `regex' function to recognize a positive response to - a yes/no question. The GNU C library provides the `rpmatch' - function for easier handling in applications. + In case the step is not the last one, the later conversion + functions have to get a chance to do their work. Therefore, the + appropriate conversion function has to be called. The information + about the functions is stored in the conversion data structures, + passed as the first parameter. This information and the step data + are stored in arrays, so the next element in both cases can be + found by simple pointer arithmetic: - `NOEXPR' - The return value is a regular expression which can be used - with the `regex' function to recognize a negative response to - a yes/no question. + int + gconv (struct __gconv_step *step, struct __gconv_step_data *data, + const char **inbuf, const char *inbufend, size_t *written, + int do_flush) + { + struct __gconv_step *next_step = step + 1; + struct __gconv_step_data *next_data = data + 1; + ... - `YESSTR' - The return value is a locale-specific translation of the - positive response to a yes/no question. + The `next_step' pointer references the next step information and + `next_data' the next data record. The call of the next function + therefore will look similar to this: - Using this value is deprecated since it is a very special - case of message translation, and is better handled by the - message translation functions (*note Message Translation::). + next_step->__fct (next_step, next_data, &outerr, outbuf, + written, 0) - The use of this symbol is deprecated. Instead message - translation should be used. + But this is not yet all. Once the function call returns the + conversion function might have some more to do. If the return + value of the function is `__GCONV_EMPTY_INPUT', more room is + available in the output buffer. Unless the input buffer is empty + the conversion, functions start all over again and process the + rest of the input buffer. If the return value is not + `__GCONV_EMPTY_INPUT', something went wrong and we have to recover + from this. - `NOSTR' - The return value is a locale-specific translation of the - negative response to a yes/no question. What is said for - `YESSTR' is also true here. + A requirement for the conversion function is that the input buffer + pointer (the third argument) always point to the last character + that was put in converted form into the output buffer. This is + trivially true after the conversion performed in the current step, + but if the conversion functions deeper downstream stop + prematurely, not all characters from the output buffer are + consumed and, therefore, the input buffer pointers must be backed + off to the right position. - The use of this symbol is deprecated. Instead message - translation should be used. + Correcting the input buffers is easy to do if the input and output + character sets have a fixed width for all characters. In this + situation we can compute how many characters are left in the + output buffer and, therefore, can correct the input buffer pointer + appropriately with a similar computation. Things are getting + tricky if either character set has characters represented with + variable length byte sequences, and it gets even more complicated + if the conversion has to take care of the state. In these cases + the conversion has to be performed once again, from the known + state before the initial conversion (i.e., if necessary the state + of the conversion has to be reset and the conversion loop has to be + executed again). The difference now is that it is known how much + input must be created, and the conversion can stop before + converting the first unused character. Once this is done the + input buffer pointers must be updated again and the function can + return. - The file `langinfo.h' defines a lot more symbols but none of them - is official. Using them is not portable, and the format of the - return values might change. Therefore we recommended you not use - them. + One final thing should be mentioned. If it is necessary for the + conversion to know whether it is the first invocation (in case a + prolog has to be emitted), the conversion function should + increment the `__invocation_counter' element of the step data + structure just before returning to the caller. See the + description of the `struct __gconv_step_data' structure above for + more information on how this can be used. - Note that the return value for any valid argument can be used for - in all situations (with the possible exception of the am/pm time - formatting codes). If the user has not selected any locale for the - appropriate category, `nl_langinfo' returns the information from - the `"C"' locale. It is therefore possible to use this function as - shown in the example below. + The return value must be one of the following values: - If the argument ITEM is not valid, a pointer to an empty string is - returned. + `__GCONV_EMPTY_INPUT' + All input was consumed and there is room left in the output + buffer. - An example of `nl_langinfo' usage is a function which has to print a -given date and time in a locale-specific way. At first one might think -that, since `strftime' internally uses the locale information, writing -something like the following is enough: + `__GCONV_FULL_OUTPUT' + No more room in the output buffer. In case this is not the + last step this value is propagated down from the call of the + next conversion function in the chain. - size_t - i18n_time_n_data (char *s, size_t len, const struct tm *tp) - { - return strftime (s, len, "%X %D", tp); - } + `__GCONV_INCOMPLETE_INPUT' + The input buffer is not entirely empty since it contains an + incomplete character sequence. - The format contains no weekday or month names and therefore is -internationally usable. Wrong! The output produced is something like -`"hh:mm:ss MM/DD/YY"'. This format is only recognizable in the USA. -Other countries use different formats. Therefore the function should -be rewritten like this: + The following example provides a framework for a conversion + function. In case a new conversion has to be written the holes in + this implementation have to be filled and that is it. - size_t - i18n_time_n_data (char *s, size_t len, const struct tm *tp) - { - return strftime (s, len, nl_langinfo (D_T_FMT), tp); - } + int + gconv (struct __gconv_step *step, struct __gconv_step_data *data, + const char **inbuf, const char *inbufend, size_t *written, + int do_flush) + { + struct __gconv_step *next_step = step + 1; + struct __gconv_step_data *next_data = data + 1; + gconv_fct fct = next_step->__fct; + int status; + + /* If the function is called with no input this means we have + to reset to the initial state.

If the user selects the locale correctly there should -never be a misunderstanding over the time and date format. + This information should be sufficient to write new modules. Anybody +doing so should also take a look at the available source code in the GNU +C library sources. It contains many examples of working and optimized +modules.  -File: libc.info, Node: Formatting Numbers, Next: Yes-or-No Questions, Prev: Locale Information, Up: Locales - -A dedicated function to format numbers -====================================== - - We have seen that the structure returned by `localeconv' as well as -the values given to `nl_langinfo' allow you to retrieve the various -pieces of locale-specific information to format numbers and monetary -amounts. We have also seen that the underlying rules are quite complex. - - Therefore the X/Open standards introduce a function which uses such -locale information, making it easier for the user to format numbers -according to these rules. - - - Function: ssize_t strfmon (char *S, size_t MAXSIZE, const char - *FORMAT, ...) - The `strfmon' function is similar to the `strftime' function in - that it takes a buffer, its size, a format string, and values to - write into the buffer as text in a form specified by the format - string. Like `strftime', the function also returns the number of - bytes written into the buffer. - - There are two differences: `strfmon' can take more than one - argument, and, of course, the format specification is different. - Like `strftime', the format string consists of normal text, which - is output as is, and format specifiers, which are indicated by a - `%'. Immediately after the `%', you can optionally specify - various flags and formatting information before the main - formatting character, in a similar way to `printf': - - * Immediately following the `%' there can be one or more of the - following flags: - `=F' - The single byte character F is used for this field as - the numeric fill character. By default this character - is a space character. Filling with this character is - only performed if a left precision is specified. It is - not just to fill to the given field width. - - `^' - The number is printed without grouping the digits - according to the rules of the current locale. By - default grouping is enabled. - - `+', `(' - At most one of these flags can be used. They select - which format to represent the sign of a currency amount. - By default, and if `+' is given, the locale equivalent - of +/- is used. If `(' is given, negative amounts are - enclosed in parentheses. The exact format is determined - by the values of the `LC_MONETARY' category of the - locale selected at program runtime. - - `!' - The output will not contain the currency symbol. - - `-' - The output will be formatted left-justified instead of - right-justified if it does not fill the entire field - width. - - The next part of a specification is an optional field width. If no - width is specified 0 is taken. During output, the function first - determines how much space is required. If it requires at least as - many characters as given by the field width, it is output using as - much space as necessary. Otherwise, it is extended to use the - full width by filling with the space character. The presence or - absence of the `-' flag determines the side at which such padding - occurs. If present, the spaces are added at the right making the - output left-justified, and vice versa. - - So far the format looks familiar, being similar to the `printf' and - `strftime' formats. However, the next two optional fields - introduce something new. The first one is a `#' character followed - by a decimal digit string. The value of the digit string - specifies the number of _digit_ positions to the left of the - decimal point (or equivalent). This does _not_ include the - grouping character when the `^' flag is not given. If the space - needed to print the number does not fill the whole width, the - field is padded at the left side with the fill character, which - can be selected using the `=' flag and by default is a space. For - example, if the field width is selected as 6 and the number is - 123, the fill character is `*' the result will be `***123'. - - The second optional field starts with a `.' (period) and consists - of another decimal digit string. Its value describes the number of - characters printed after the decimal point. The default is - selected from the current locale (`frac_digits', - `int_frac_digits', see *note General Numeric::). If the exact - representation needs more digits than given by the field width, - the displayed value is rounded. If the number of fractional - digits is selected to be zero, no decimal point is printed. - - As a GNU extension, the `strfmon' implementation in the GNU libc - allows an optional `L' next as a format modifier. If this modifier - is given, the argument is expected to be a `long double' instead of - a `double' value. - - Finally, the last component is a format specifier. There are three - specifiers defined: - - `i' - Use the locale's rules for formatting an international - currency value. +File: libc.info, Node: Locales, Next: Message Translation, Prev: Character Set Handling, Up: Top - `n' - Use the locale's rules for formatting a national currency - value. +Locales and Internationalization +******************************** - `%' - Place a `%' in the output. There must be no flag, width - specifier or modifier given, only `%%' is allowed. + Different countries and cultures have varying conventions for how to +communicate. These conventions range from very simple ones, such as the +format for representing dates and times, to very complex ones, such as +the language spoken. - As for `printf', the function reads the format string from left to - right and uses the values passed to the function following the - format string. The values are expected to be either of type - `double' or `long double', depending on the presence of the - modifier `L'. The result is stored in the buffer pointed to by S. - At most MAXSIZE characters are stored. + "Internationalization" of software means programming it to be able +to adapt to the user's favorite conventions. In ISO C, +internationalization works by means of "locales". Each locale +specifies a collection of conventions, one convention for each purpose. +The user chooses a set of conventions by specifying a locale (via +environment variables). - The return value of the function is the number of characters - stored in S, including the terminating `NULL' byte. If the number - of characters stored would exceed MAXSIZE, the function returns -1 - and the content of the buffer S is unspecified. In this case - `errno' is set to `E2BIG'. + All programs inherit the chosen locale as part of their environment. +Provided the programs are written to obey the choice of locale, they +will follow the conventions preferred by the user. - A few examples should make clear how the function works. It is -assumed that all the following pieces of code are executed in a program -which uses the USA locale (`en_US'). The simplest form of the format -is this: +* Menu: - strfmon (buf, 100, "@%n@%n@%n@", 123.45, -567.89, 12345.678); +* Effects of Locale:: Actions affected by the choice of + locale. +* Choosing Locale:: How the user specifies a locale. +* Locale Categories:: Different purposes for which you can + select a locale. +* Setting the Locale:: How a program specifies the locale + with library functions. +* Standard Locales:: Locale names available on all systems. +* Locale Information:: How to access the information for the locale. +* Formatting Numbers:: A dedicated function to format numbers. +* Yes-or-No Questions:: Check a Response against the locale. -The output produced is - "@$123.45@-$567.89@$12,345.68@" + +File: libc.info, Node: Effects of Locale, Next: Choosing Locale, Up: Locales - We can notice several things here. First, the widths of the output -numbers are different. We have not specified a width in the format -string, and so this is no wonder. Second, the third number is printed -using thousands separators. The thousands separator for the `en_US' -locale is a comma. The number is also rounded. .678 is rounded to .68 -since the format does not specify a precision and the default value in -the locale is 2. Finally, note that the national currency symbol is -printed since `%n' was used, not `i'. The next example shows how we -can align the output. +What Effects a Locale Has +========================= - strfmon (buf, 100, "@%=*11n@%=*11n@%=*11n@", 123.45, -567.89, 12345.678); + Each locale specifies conventions for several purposes, including the +following: -The output this time is: + * What multibyte character sequences are valid, and how they are + interpreted (*note Character Set Handling::). - "@ $123.45@ -$567.89@ $12,345.68@" + * Classification of which characters in the local character set are + considered alphabetic, and upper- and lower-case conversion + conventions (*note Character Handling::). - Two things stand out. Firstly, all fields have the same width -(eleven characters) since this is the width given in the format and -since no number required more characters to be printed. The second -important point is that the fill character is not used. This is -correct since the white space was not used to achieve a precision given -by a `#' modifier, but instead to fill to the given width. The -difference becomes obvious if we now add a width specification. + * The collating sequence for the local language and character set + (*note Collation Functions::). - strfmon (buf, 100, "@%=*11#5n@%=*11#5n@%=*11#5n@", - 123.45, -567.89, 12345.678); + * Formatting of numbers and currency amounts (*note General + Numeric::). -The output is + * Formatting of dates and times (*note Formatting Calendar Time::). - "@ $***123.45@-$***567.89@ $12,456.68@" + * What language to use for output, including error messages (*note + Message Translation::). - Here we can see that all the currency symbols are now aligned, and -that the space between the currency sign and the number is filled with -the selected fill character. Note that although the width is selected -to be 5 and 123.45 has three digits left of the decimal point, the -space is filled with three asterisks. This is correct since, as -explained above, the width does not include the positions used to store -thousands separators. One last example should explain the remaining -functionality. + * What language to use for user answers to yes-or-no questions + (*note Yes-or-No Questions::). - strfmon (buf, 100, "@%=0(16#5.3i@%=0(16#5.3i@%=0(16#5.3i@", - 123.45, -567.89, 12345.678); + * What language to use for more complex user input. (The C library + doesn't yet help you implement this.) -This rather complex format string produces the following output: + Some aspects of adapting to the specified locale are handled +automatically by the library subroutines. For example, all your program +needs to do in order to use the collating sequence of the chosen locale +is to use `strcoll' or `strxfrm' to compare strings. - "@ USD 000123,450 @(USD 000567.890)@ USD 12,345.678 @" + Other aspects of locales are beyond the comprehension of the library. +For example, the library can't automatically translate your program's +output messages into other languages. The only way you can support +output in the user's favorite language is to program this more or less +by hand. The C library provides functions to handle translations for +multiple languages easily. - The most noticeable change is the alternative way of representing -negative numbers. In financial circles this is often done using -parentheses, and this is what the `(' flag selected. The fill -character is now `0'. Note that this `0' character is not regarded as -a numeric zero, and therefore the first and second numbers are not -printed using a thousands separator. Since we used the format -specifier `i' instead of `n', the international form of the currency -symbol is used. This is a four letter string, in this case `"USD "'. -The last point is that since the precision right of the decimal point -is selected to be three, the first and second numbers are printed with -an extra zero at the end and the third number is printed without -rounding. + This chapter discusses the mechanism by which you can modify the +current locale.

We can't make any promises about what +locales will exist, except for one standard locale called `C' or +`POSIX'. Later we will describe how to construct locales. -This function would normally be used like this: + A user also has the option of specifying different locales for +different purposes--in effect, choosing a mixture of multiple locales. - ... - /* Use a safe default. */ - _Bool doit = false; - - fputs (gettext ("Do you really want to do this?

This means for the programmer that +Accessing Locale Information +============================ - * the STRING parameters should contain reasonable text (this - also helps to understand the program seems otherwise there - would be no hint on the string which is expected to be - returned. + There are several ways to access locale information. The simplest +way is to let the C library itself do the work. Several of the +functions in this library implicitly access the locale data, and use +what information is provided by the currently selected locale. This is +how the locale model is meant to work normally. - * all STRING arguments should be written in the same language. + As an example take the `strftime' function, which is meant to nicely +format date and time information (*note Formatting Calendar Time::). +Part of the standard information contained in the `LC_TIME' category is +the names of the months. Instead of requiring the programmer to take +care of providing the translations the `strftime' function does this +all by itself. `%A' in the format string is replaced by the +appropriate weekday name of the locale currently selected by `LC_TIME'. +This is an easy example, and wherever possible functions do things +automatically in this way. - It is somewhat uncomfortable to write a program using the `catgets' -functions if no supporting functionality is available. Since each -set/message number tuple must be unique the programmer must keep lists -of the messages at the same time the code is written. And the work -between several people working on the same project must be coordinated. -We will see some how these problems can be relaxed a bit (*note Common -Usage::). + But there are quite often situations when there is simply no function +to perform the task, or it is simply not possible to do the work +automatically. For these cases it is necessary to access the +information in the locale directly. To do this the C library provides +two functions: `localeconv' and `nl_langinfo'.

Systems strictly following the -X/Open specification do not have this feature.

Otherwise the quotes in the - message definition would have to be left away and in this case the - message with the identifier `two' would loose its leading - whitespace. + Each country has two standard currency symbols. The "local currency +symbol" is used commonly within the country, while the "international +currency symbol" is used internationally to refer to that country's +currency when it is necessary to indicate the country unambiguously. - * Mixing numbered messages with message having symbolic names is no - problem and the numbering happens automatically. + For example, many countries use the dollar as their monetary unit, +and when dealing with international currencies it's important to specify +that one is dealing with (say) Canadian dollars instead of U.S. dollars +or Australian dollars.

By -following slavishly the X/Open specs and not relying on the extension -and by using the GNU extensions. We will take a look at the former -method first to understand the benefits of extensions. + When writing the X/Open Portability Guide the authors realized that +the `localeconv' function is not enough to provide reasonable access to +locale information. The information which was meant to be available in +the locale (as later specified in the POSIX.1 standard) requires more +ways to access it. Therefore the `nl_langinfo' function was introduced. -Not using symbolic names -........................ + - Function: char * nl_langinfo (nl_item ITEM) + The `nl_langinfo' function can be used to access individual + elements of the locale categories. Unlike the `localeconv' + function, which returns all the information, `nl_langinfo' lets + the caller select what information it requires. This is very fast + and it is not a problem to call this function multiple times. - Since the X/Open format of the message catalog files does not allow -symbol names we have to work with numbers all the time. When we start -writing a program we have to replace all appearances of translatable -strings with something like + A second advantage is that in addition to the numeric and monetary + formatting information, information from the `LC_TIME' and + `LC_MESSAGES' categories is available. - catgets (catdesc, set, msg, "string") + The type `nl_type' is defined in `nl_types.h'. The argument ITEM + is a numeric value defined in the header `langinfo.h'. The X/Open + standard defines the following values: -CATGETS is retrieved from a call to `catopen' which is normally done -once at the program start. The `"string"' is the string we want to -translate. The problems start with the set and message numbers. + `CODESET' + `nl_langinfo' returns a string with the name of the coded + character set used in the selected locale. - In a bigger program several programmers usually work at the same -time on the program and so coordinating the number allocation is -crucial. Though no two different strings must be indexed by the same -tuple of numbers it is highly desirable to reuse the numbers for equal -strings with equal translations (please note that there might be -strings which are equal in one language but have different translations -due to difference contexts). + `ABDAY_1' + `ABDAY_2' + `ABDAY_3' + `ABDAY_4' + `ABDAY_5' + `ABDAY_6' + `ABDAY_7' + `nl_langinfo' returns the abbreviated weekday name. `ABDAY_1' + corresponds to Sunday. - The allocation process can be relaxed a bit by different set numbers -for different parts of the program. So the number of developers who -have to coordinate the allocation can be reduced. But still lists must -be keep track of the allocation and errors can easily happen. These -errors cannot be discovered by the compiler or the `catgets' functions. -Only the user of the program might see wrong messages printed. In the -worst cases the messages are so irritating that they cannot be -recognized as wrong. Think about the translations for `"true"' and -`"false"' being exchanged. This could result in a disaster. + `DAY_1' + `DAY_2' + `DAY_3' + `DAY_4' + `DAY_5' + `DAY_6' + `DAY_7' + Similar to `ABDAY_1' etc., but here the return value is the + unabbreviated weekday name. -Using symbolic names -.................... + `ABMON_1' + `ABMON_2' + `ABMON_3' + `ABMON_4' + `ABMON_5' + `ABMON_6' + `ABMON_7' + `ABMON_8' + `ABMON_9' + `ABMON_10' + `ABMON_11' + `ABMON_12' + The return value is abbreviated name of the month. `ABMON_1' + corresponds to January. - The problems mentioned in the last section derive from the fact that: + `MON_1' + `MON_2' + `MON_3' + `MON_4' + `MON_5' + `MON_6' + `MON_7' + `MON_8' + `MON_9' + `MON_10' + `MON_11' + `MON_12' + Similar to `ABMON_1' etc., but here the month names are not + abbreviated. Here the first value `MON_1' also corresponds + to January. - 1. the numbers are allocated once and due to the possibly frequent - use of them it is difficult to change a number later. + `AM_STR' + `PM_STR' + The return values are strings which can be used in the + representation of time as an hour from 1 to 12 plus an am/pm + specifier. - 2. the numbers do not allow to guess anything about the string and - therefore collisions can easily happen. + Note that in locales which do not use this time representation + these strings might be empty, in which case the am/pm format + cannot be used at all. - By constantly using symbolic names and by providing a method which -maps the string content to a symbolic name (however this will happen) -one can prevent both problems above. The cost of this is that the -programmer has to write a complete message catalog file while s/he is -writing the program itself. + `D_T_FMT' + The return value can be used as a format string for + `strftime' to represent time and date in a locale-specific + way. - This is necessary since the symbolic names must be mapped to numbers -before the program sources can be compiled. In the last section it was -described how to generate a header containing the mapping of the names. -E.g., for the example message file given in the last section we could -call the `gencat' program as follow (assume `ex.msg' contains the -sources). + `D_FMT' + The return value can be used as a format string for + `strftime' to represent a date in a locale-specific way. - gencat -H ex.h -o ex.cat ex.msg + `T_FMT' + The return value can be used as a format string for + `strftime' to represent time in a locale-specific way. -This generates a header file with the following content: + `T_FMT_AMPM' + The return value can be used as a format string for + `strftime' to represent time in the am/pm format. - #define SetTwoSet 0x2 /* ex.msg:8 */ - - #define SetOneSet 0x1 /* ex.msg:4 */ - #define SetOnetwo 0x2 /* ex.msg:6 */ + Note that if the am/pm format does not make any sense for the + selected locale, the return value might be the same as the + one for `T_FMT'. - As can be seen the various symbols given in the source file are -mangled to generate unique identifiers and these identifiers get numbers -assigned. Reading the source file and knowing about the rules will -allow to predict the content of the header file (it is deterministic) -but this is not necessary. The `gencat' program can take care for -everything. All the programmer has to do is to put the generated header -file in the dependency list of the source files of her/his project and -to add a rules to regenerate the header of any of the input files -change. + `ERA' + The return value represents the era used in the current + locale. - One word about the symbol mangling. Every symbol consists of two -parts: the name of the message set plus the name of the message or the -special string `Set'. So `SetOnetwo' means this macro can be used to -access the translation with identifier `two' in the message set -`SetOne'. + Most locales do not define this value. An example of a + locale which does define this value is the Japanese one. In + Japan, the traditional representation of dates includes the + name of the era corresponding to the then-emperor's reign. - The other names denote the names of the message sets. The special -string `Set' is used in the place of the message identifier. + Normally it should not be necessary to use this value + directly. Specifying the `E' modifier in their format + strings causes the `strftime' functions to use this + information. The format of the returned string is not + specified, and therefore you should not assume knowledge of + it on different systems. - If in the code the second string of the set `SetOne' is used the C -code should look like this: + `ERA_YEAR' + The return value gives the year in the relevant era of the + locale. As for `ERA' it should not be necessary to use this + value directly. - catgets (catdesc, SetOneSet, SetOnetwo, - " Message with ID \"two\", which gets the value 2 assigned") + `ERA_D_T_FMT' + This return value can be used as a format string for + `strftime' to represent dates and times in a locale-specific + era-based way. - Writing the function this way will allow to change the message number -and even the set number without requiring any change in the C source -code. (The text of the string is normally not the same; this is only -for this example.) + `ERA_D_FMT' + This return value can be used as a format string for + `strftime' to represent a date in a locale-specific era-based + way. -How does to this allow to develop -................................. + `ERA_T_FMT' + This return value can be used as a format string for + `strftime' to represent time in a locale-specific era-based + way. - To illustrate the usual way to work with the symbolic version numbers -here is a little example.

The default is + selected from the current locale (`frac_digits', + `int_frac_digits', see *note General Numeric::). If the exact + representation needs more digits than given by the field width, + the displayed value is rounded. If the number of fractional + digits is selected to be zero, no decimal point is printed. - The paradigms underlying the `gettext' approach to message -translations is different from that of the `catgets' functions the -basic functionally is equivalent. There are functions of the following -categories: + As a GNU extension, the `strfmon' implementation in the GNU libc + allows an optional `L' next as a format modifier. If this modifier + is given, the argument is expected to be a `long double' instead of + a `double' value. -* Menu: + Finally, the last component is a format specifier. There are three + specifiers defined: -* Translation with gettext:: What has to be done to translate a message. -* Locating gettext catalog:: How to determine which catalog to be used. -* Advanced gettext functions:: Additional functions for more complicated - situations. -* Charset conversion in gettext:: How to specify the output character set - `gettext' uses. -* GUI program problems:: How to use `gettext' in GUI programs. -* Using gettextized software:: The possibilities of the user to influence - the way `gettext' works. + `i' + Use the locale's rules for formatting an international + currency value. - -File: libc.info, Node: Translation with gettext, Next: Locating gettext catalog, Up: Message catalogs with gettext + `n' + Use the locale's rules for formatting a national currency + value. -What has to be done to translate a message? -........................................... + `%' + Place a `%' in the output. There must be no flag, width + specifier or modifier given, only `%%' is allowed. - The `gettext' functions have a very simple interface. The most -basic function just takes the string which shall be translated as the -argument and it returns the translation. This is fundamentally -different from the `catgets' approach where an extra key is necessary -and the original string is only used for the error case. + As for `printf', the function reads the format string from left to + right and uses the values passed to the function following the + format string. The values are expected to be either of type + `double' or `long double', depending on the presence of the + modifier `L'. The result is stored in the buffer pointed to by S. + At most MAXSIZE characters are stored. - If the string which has to be translated is the only argument this of -course means the string itself is the key. I.e., the translation will -be selected based on the original string. The message catalogs must -therefore contain the original strings plus one translation for any such -string. The task of the `gettext' function is it to compare the -argument string with the available strings in the catalog and return the -appropriate translation. Of course this process is optimized so that -this process is not more expensive than an access using an atomic key -like in `catgets'. + The return value of the function is the number of characters + stored in S, including the terminating `NULL' byte. If the number + of characters stored would exceed MAXSIZE, the function returns -1 + and the content of the buffer S is unspecified. In this case + `errno' is set to `E2BIG'. - The `gettext' approach has some advantages but also some -disadvantages. Please see the GNU `gettext' manual for a detailed -discussion of the pros and cons. + A few examples should make clear how the function works. It is +assumed that all the following pieces of code are executed in a program +which uses the USA locale (`en_US'). The simplest form of the format +is this: - All the definitions and declarations for `gettext' can be found in -the `libintl.h' header file. On systems where these functions are not -part of the C library they can be found in a separate library named -`libintl.a' (or accordingly different for shared libraries). + strfmon (buf, 100, "@%n@%n@%n@", 123.45, -567.89, 12345.678); - - Function: char * gettext (const char *MSGID) - The `gettext' function searches the currently selected message - catalogs for a string which is equal to MSGID. If there is such a - string available it is returned. Otherwise the argument string - MSGID is returned. +The output produced is + "@$123.45@-$567.89@$12,345.68@" - Please note that all though the return value is `char *' the - returned string must not be changed. This broken type results - from the history of the function and does not reflect the way the - function should be used. + We can notice several things here. First, the widths of the output +numbers are different. We have not specified a width in the format +string, and so this is no wonder. Second, the third number is printed +using thousands separators. The thousands separator for the `en_US' +locale is a comma. The number is also rounded. .678 is rounded to .68 +since the format does not specify a precision and the default value in +the locale is 2. Finally, note that the national currency symbol is +printed since `%n' was used, not `i'. The next example shows how we +can align the output. - Please note that above we wrote "message catalogs" (plural). This - is a specialty of the GNU implementation of these functions and we - will say more about this when we talk about the ways message - catalogs are selected (*note Locating gettext catalog::). + strfmon (buf, 100, "@%=*11n@%=*11n@%=*11n@", 123.45, -567.89, 12345.678); - The `gettext' function does not modify the value of the global - ERRNO variable. This is necessary to make it possible to write - something like +The output this time is: - printf (gettext ("Operation failed: %m\n")); + "@ $123.45@ -$567.89@ $12,345.68@" - Here the ERRNO value is used in the `printf' function while - processing the `%m' format element and if the `gettext' function - would change this value (it is called before `printf' is called) - we would get a wrong message. + Two things stand out. Firstly, all fields have the same width +(eleven characters) since this is the width given in the format and +since no number required more characters to be printed. The second +important point is that the fill character is not used. This is +correct since the white space was not used to achieve a precision given +by a `#' modifier, but instead to fill to the given width. The +difference becomes obvious if we now add a width specification. - So there is no easy way to detect a missing message catalog beside - comparing the argument string with the result. But it is normally - the task of the user to react on missing catalogs. The program - cannot guess when a message catalog is really necessary since for - a user who speaks the language the program was developed in does - not need any translation. + strfmon (buf, 100, "@%=*11#5n@%=*11#5n@%=*11#5n@", + 123.45, -567.89, 12345.678); - The remaining two functions to access the message catalog add some -functionality to select a message catalog which is not the default one. -This is important if parts of the program are developed independently. -Every part can have its own message catalog and all of them can be used -at the same time. The C library itself is an example: internally it -uses the `gettext' functions but since it must not depend on a -currently selected default message catalog it must specify all ambiguous -information. +The output is - - Function: char * dgettext (const char *DOMAINNAME, const char *MSGID) - The `dgettext' functions acts just like the `gettext' function. - It only takes an additional first argument DOMAINNAME which guides - the selection of the message catalogs which are searched for the - translation. If the DOMAINNAME parameter is the null pointer the - `dgettext' function is exactly equivalent to `gettext' since the - default value for the domain name is used. + "@ $***123.45@-$***567.89@ $12,456.68@" - As for `gettext' the return value type is `char *' which is an - anachronism. The returned string must never be modified. + Here we can see that all the currency symbols are now aligned, and +that the space between the currency sign and the number is filled with +the selected fill character. Note that although the width is selected +to be 5 and 123.45 has three digits left of the decimal point, the +space is filled with three asterisks. This is correct since, as +explained above, the width does not include the positions used to store +thousands separators. One last example should explain the remaining +functionality. - - Function: char * dcgettext (const char *DOMAINNAME, const char - *MSGID, int CATEGORY) - The `dcgettext' adds another argument to those which `dgettext' - takes. This argument CATEGORY specifies the last piece of - information needed to localize the message catalog. I.e., the - domain name and the locale category exactly specify which message - catalog has to be used (relative to a given directory, see below). + strfmon (buf, 100, "@%=0(16#5.3i@%=0(16#5.3i@%=0(16#5.3i@", + 123.45, -567.89, 12345.678); - The `dgettext' function can be expressed in terms of `dcgettext' - by using +This rather complex format string produces the following output: - dcgettext (domain, string, LC_MESSAGES) + "@ USD 000123,450 @(USD 000567.890)@ USD 12,345.678 @" - instead of + The most noticeable change is the alternative way of representing +negative numbers. In financial circles this is often done using +parentheses, and this is what the `(' flag selected. The fill +character is now `0'. Note that this `0' character is not regarded as +a numeric zero, and therefore the first and second numbers are not +printed using a thousands separator. Since we used the format +specifier `i' instead of `n', the international form of the currency +symbol is used. This is a four letter string, in this case `"USD "'. +The last point is that since the precision right of the decimal point +is selected to be three, the first and second numbers are printed with +an extra zero at the end and the third number is printed without +rounding. - dgettext (domain, string) + +File: libc.info, Node: Yes-or-No Questions, Prev: Formatting Numbers, Up: Locales - This also shows which values are expected for the third parameter. - One has to use the available selectors for the categories - available in `locale.h'. Normally the available values are - `LC_CTYPE', `LC_COLLATE', `LC_MESSAGES', `LC_MONETARY', - `LC_NUMERIC', and `LC_TIME'. Please note that `LC_ALL' must not - be used and even though the names might suggest this, there is no - relation to the environments variables of this name. +Yes-or-No Questions +=================== - The `dcgettext' function is only implemented for compatibility with - other systems which have `gettext' functions. There is not really - any situation where it is necessary (or useful) to use a different - value but `LC_MESSAGES' in for the CATEGORY parameter. We are - dealing with messages here and any other choice can only be - irritating. + Some non GUI programs ask a yes-or-no question. If the messages +(especially the questions) are translated into foreign languages, be +sure that you localize the answers too. It would be very bad habit to +ask a question in one language and request the answer in another, often +English. - As for `gettext' the return value type is `char *' which is an - anachronism. The returned string must never be modified. + The GNU C library contains `rpmatch' to give applications easy +access to the corresponding locale definitions. - When using the three functions above in a program it is a frequent -case that the MSGID argument is a constant string. So it is worth to -optimize this case. Thinking shortly about this one will realize that -as long as no new message catalog is loaded the translation of a message -will not change. This optimization is actually implemented by the -`gettext', `dgettext' and `dcgettext' functions. + - Function: int rpmatch (const char *RESPONSE) + The function `rpmatch' checks the string in RESPONSE whether or + not it is a correct yes-or-no answer and if yes, which one. The + check uses the `YESEXPR' and `NOEXPR' data in the `LC_MESSAGES' + category of the currently selected locale. The return value is as + follows: - -File: libc.info, Node: Locating gettext catalog, Next: Advanced gettext functions, Prev: Translation with gettext, Up: Message catalogs with gettext + `1' + The user entered an affirmative answer. -How to determine which catalog to be used -......................................... + `0' + The user entered a negative answer. - The functions to retrieve the translations for a given message have a -remarkable simple interface. But to provide the user of the program -still the opportunity to select exactly the translation s/he wants and -also to provide the programmer the possibility to influence the way to -locate the search for catalogs files there is a quite complicated -underlying mechanism which controls all this. The code is complicated -the use is easy. + `-1' + The answer matched neither the `YESEXPR' nor the `NOEXPR' + regular expression. - Basically we have two different tasks to perform which can also be -performed by the `catgets' functions: + This function is not standardized but available beside in GNU libc + at least also in the IBM AIX library. - 1. Locate the set of message catalogs. There are a number of files - for different languages and which all belong to the package. - Usually they are all stored in the filesystem below a certain - directory. +This function would normally be used like this: - There can be arbitrary many packages installed and they can follow - different guidelines for the placement of their files. + ... + /* Use a safe default. */ + _Bool doit = false; + + fputs (gettext ("Do you really want to do this? "), stdout); + fflush (stdout); + /* Prepare the `getline' call. */ + line = NULL; + len = 0; + while (getline (&line, &len, stdout) >= 0) + { + /* Check the response. */ + int res = rpmatch (line); + if (res >= 0) + { + /* We got a definitive answer. */ + if (res > 0) + doit = true; + break; + } + } + /* Free what `getline' allocated. */ + free (line); - 2. Relative to the location specified by the package the actual - translation files must be searched, based on the wishes of the - user. I.e., for each language the user selects the program should - be able to locate the appropriate file. + Note that the loop continues until an read error is detected or +until a definitive (positive or negative) answer is read. - This is the functionality required by the specifications for -`gettext' and this is also what the `catgets' functions are able to do. -But there are some problems unresolved: + +File: libc.info, Node: Message Translation, Next: Searching and Sorting, Prev: Locales, Up: Top - * The language to be used can be specified in several different ways. - There is no generally accepted standard for this and the user - always expects the program understand what s/he means. E.g., to - select the German translation one could write `de', `german', or - `deutsch' and the program should always react the same. +Message Translation +******************* - * Sometimes the specification of the user is too detailed. If s/he, - e.g., specifies `de_DE.ISO-8859-1' which means German, spoken in - Germany, coded using the ISO 8859-1 character set there is the - possibility that a message catalog matching this exactly is not - available. But there could be a catalog matching `de' and if the - character set used on the machine is always ISO 8859-1 there is no - reason why this later message catalog should not be used. (We - call this "message inheritance".) + The program's interface with the human should be designed in a way to +ease the human the task. One of the possibilities is to use messages in +whatever language the user prefers. - * If a catalog for a wanted language is not available it is not - always the second best choice to fall back on the language of the - developer and simply not translate any message. Instead a user - might be better able to read the messages in another language and - so the user of the program should be able to define an precedence - order of languages. + Printing messages in different languages can be implemented in +different ways. One could add all the different languages in the +source code and add among the variants every time a message has to be +printed. This is certainly no good solution since extending the set of +languages is difficult (the code must be changed) and the code itself +can become really big with dozens of message sets. - We can divide the configuration actions in two parts: the one is -performed by the programmer, the other by the user. We will start with -the functions the programmer can use since the user configuration will -be based on this. + A better solution is to keep the message sets for each language are +kept in separate files which are loaded at runtime depending on the +language selection of the user. - As the functions described in the last sections already mention -separate sets of messages can be selected by a "domain name". This is a -simple string which should be unique for each program part with uses a -separate domain. It is possible to use in one program arbitrary many -domains at the same time. E.g., the GNU C Library itself uses a domain -named `libc' while the program using the C Library could use a domain -named `foo'. The important point is that at any time exactly one -domain is active. This is controlled with the following function. + The GNU C Library provides two different sets of functions to support +message translation. The problem is that neither of the interfaces is +officially defined by the POSIX standard. The `catgets' family of +functions is defined in the X/Open standard but this is derived from +industry decisions and therefore not necessarily based on reasonable +decisions. - - Function: char * textdomain (const char *DOMAINNAME) - The `textdomain' function sets the default domain, which is used in - all future `gettext' calls, to DOMAINNAME. Please note that - `dgettext' and `dcgettext' calls are not influenced if the - DOMAINNAME parameter of these functions is not the null pointer. + As mentioned above the message catalog handling provides easy +extendibility by using external data files which contain the message +translations. I.e., these files contain for each of the messages used +in the program a translation for the appropriate language. So the tasks +of the message handling functions are - Before the first call to `textdomain' the default domain is - `messages'. This is the name specified in the specification of - the `gettext' API. This name is as good as any other name. No - program should ever really use a domain with this name since this - can only lead to problems. + * locate the external data file with the appropriate translations. - The function returns the value which is from now on taken as the - default domain. If the system went out of memory the returned - value is `NULL' and the global variable ERRNO is set to `ENOMEM'. - Despite the return value type being `char *' the return string must - not be changed. It is allocated internally by the `textdomain' - function. + * load the data and make it possible to address the messages - If the DOMAINNAME parameter is the null pointer no new default - domain is set. Instead the currently selected default domain is - returned. + * map a given key to the translated message - If the DOMAINNAME parameter is the empty string the default domain - is reset to its initial value, the domain with the name `messages'. - This possibility is questionable to use since the domain `messages' - really never should be used. + The two approaches mainly differ in the implementation of this last +step. The design decisions made for this influences the whole rest. - - Function: char * bindtextdomain (const char *DOMAINNAME, const char - *DIRNAME) - The `bindtextdomain' function can be used to specify the directory - which contains the message catalogs for domain DOMAINNAME for the - different languages. To be correct, this is the directory where - the hierarchy of directories is expected. Details are explained - below. +* Menu: - For the programmer it is important to note that the translations - which come with the program have be placed in a directory - hierarchy starting at, say, `/foo/bar'. Then the program should - make a `bindtextdomain' call to bind the domain for the current - program to this directory. So it is made sure the catalogs are - found. A correctly running program does not depend on the user - setting an environment variable. +* Message catalogs a la X/Open:: The `catgets' family of functions. +* The Uniforum approach:: The `gettext' family of functions. - The `bindtextdomain' function can be used several times and if the - DOMAINNAME argument is different the previously bound domains will - not be overwritten. + +File: libc.info, Node: Message catalogs a la X/Open, Next: The Uniforum approach, Up: Message Translation - If the program which wish to use `bindtextdomain' at some point of - time use the `chdir' function to change the current working - directory it is important that the DIRNAME strings ought to be an - absolute pathname. Otherwise the addressed directory might vary - with the time. +X/Open Message Catalog Handling +=============================== - If the DIRNAME parameter is the null pointer `bindtextdomain' - returns the currently selected directory for the domain with the - name DOMAINNAME. + The `catgets' functions are based on the simple scheme: - The `bindtextdomain' function returns a pointer to a string - containing the name of the selected directory name. The string is - allocated internally in the function and must not be changed by the - user. If the system went out of core during the execution of - `bindtextdomain' the return value is `NULL' and the global - variable ERRNO is set accordingly. + Associate every message to translate in the source code with a + unique identifier. To retrieve a message from a catalog file + solely the identifier is used. + + This means for the author of the program that s/he will have to make +sure the meaning of the identifier in the program code and in the +message catalogs are always the same. + + Before a message can be translated the catalog file must be located. +The user of the program must be able to guide the responsible function +to find whatever catalog the user wants.

What is -meant here is the handling of plural forms. +The `catgets' function family +----------------------------- - Looking through Unix source code before the time anybody thought -about internationalization (and, sadly, even afterwards) one can often -find code similar to the following: + - Function: nl_catd catopen (const char *CAT_NAME, int FLAG) + The `catgets' function tries to locate the message data file names + CAT_NAME and loads it when found. The return value is of an + opaque type and can be used in calls to the other functions to + refer to this loaded catalog. - printf ("%d file%s deleted", n, n == 1 ?

But even if the function call + succeeded this does not mean that all messages can be translated. -After the first complaints from people internationalizing the code -people either completely avoided formulations like this or used strings -like `"file(s)"'. Both look unnatural and should be avoided. First -tries to solve the problem correctly looked like this: + Locating the catalog file must happen in a way which lets the user + of the program influence the decision. It is up to the user to + decide about the language to use and sometimes it is useful to use + alternate catalog files. All this can be specified by the user by + setting some environment variables. - if (n == 1) - printf ("%d file deleted", n); - else - printf ("%d files deleted", n); + The first problem is to find out where all the message catalogs are + stored. Every program could have its own place to keep all the + different files but usually the catalog files are grouped by + languages and the catalogs for all programs are kept in the same + place. - But this does not solve the problem. It helps languages where the -plural form of a noun is not simply constructed by adding an `s' but -that is all. Once again people fell into the trap of believing the -rules their language is using are universal. But the handling of plural -forms differs widely between the language families. There are two -things we can differ between (and even inside language families); + To tell the `catopen' function where the catalog for the program + can be found the user can set the environment variable `NLSPATH' to + a value which describes her/his choice. Since this value must be + usable for different languages and locales it cannot be a simple + string. Instead it is a format string (similar to `printf''s). + An example is - * The form how plural forms are build differs. This is a problem - with language which have many irregularities. German, for - instance, is a drastic case. Though English and German are part - of the same language family (Germanic), the almost regular forming - of plural noun forms (appending an `s') is hardly found in German. + /usr/share/locale/%L/%N:/usr/share/locale/%L/LC_MESSAGES/%N - * The number of plural forms differ. This is somewhat surprising for - those who only have experiences with Romanic and Germanic languages - since here the number is the same (there are two). + First one can see that more than one directory can be specified + (with the usual syntax of separating them by colons). The next + things to observe are the format string, `%L' and `%N' in this + case. The `catopen' function knows about several of them and the + replacement for all of them is of course different. - But other language families have only one form or many forms. More - information on this in an extra section. + `%N' + This format element is substituted with the name of the + catalog file. This is the value of the CAT_NAME argument + given to `catgets'. - The consequence of this is that application writers should not try to -solve the problem in their code. This would be localization since it is -only usable for certain, hardcoded language environments. Instead the -extended `gettext' interface should be used. + `%L' + This format element is substituted with the name of the + currently selected locale for translating messages. How this + is determined is explained below. - These extra functions are taking instead of the one key string two -strings and an numerical argument. The idea behind this is that using -the numerical argument and the first string as a key, the implementation -can select using rules specified by the translator the right plural -form. The two string arguments then will be used to provide a return -value in case no message catalog is found (similar to the normal -`gettext' behavior). In this case the rules for Germanic language is -used and it is assumed that the first string argument is the singular -form, the second the plural form. + `%l' + (This is the lowercase ell.) This format element is + substituted with the language element of the locale name. + The string describing the selected locale is expected to have + the form `LANG[_TERR[.CODESET]]' and this format uses the + first part LANG. - This has the consequence that programs without language catalogs can -display the correct strings only if the program itself is written using -a Germanic language. This is a limitation but since the GNU C library -(as well as the GNU `gettext' package) are written as part of the GNU -package and the coding standards for the GNU project require program -being written in English, this solution nevertheless fulfills its -purpose. + `%t' + This format element is substituted by the territory part TERR + of the name of the currently selected locale. See the + explanation of the format above. - - Function: char * ngettext (const char *MSGID1, const char *MSGID2, - unsigned long int N) - The `ngettext' function is similar to the `gettext' function as it - finds the message catalogs in the same way. But it takes two - extra arguments. The MSGID1 parameter must contain the singular - form of the string to be converted. It is also used as the key - for the search in the catalog. The MSGID2 parameter is the plural - form. The parameter N is used to determine the plural form. If no - message catalog is found MSGID1 is returned if `n == 1', otherwise - `msgid2'. + `%c' + This format element is substituted by the codeset part + CODESET of the name of the currently selected locale. See + the explanation of the format above. - An example for the us of this function is: + `%%' + Since `%' is used in a meta character there must be a way to + express the `%' character in the result itself. Using `%%' + does this just like it works for `printf'. - printf (ngettext ("%d file removed", "%d files removed", n), n); + Using `NLSPATH' allows arbitrary directories to be searched for + message catalogs while still allowing different languages to be + used. If the `NLSPATH' environment variable is not set, the + default value is - Please note that the numeric value N has to be passed to the - `printf' function as well.

The problem is the selection of the character to - separate the prefix from the actual string in the enlenghtened - string. The examples above used `|' which is a quite good choice - because it resembles a notation frequently used in this context - and it also is a character not often used in message strings. + Since the X/Open format of the message catalog files does not allow +symbol names we have to work with numbers all the time.

The wrapper function -above require that the translations strings are not enlengthened -themselves. This is only logical. There is no need to disambiguate -the strings (since they are never used as keys for a search) and one -also saves quite some memory and disk space by doing this. +CATGETS is retrieved from a call to `catopen' which is normally done +once at the program start.

It is computed -from the value given as the prefix while configuring the C library. -This value normally is `/usr' or `/'. For the former the complete -DIR_NAME is: + By constantly using symbolic names and by providing a method which +maps the string content to a symbolic name (however this will happen) +one can prevent both problems above. The cost of this is that the +programmer has to write a complete message catalog file while s/he is +writing the program itself. - /usr/share/locale + This is necessary since the symbolic names must be mapped to numbers +before the program sources can be compiled.

If we -would set `LC_ALL' to a value following the extended syntax that would -mean the `setlocale' function will never be able to use the value of -this variable as well. An additional variable removes this problem -plus we can select the language independently of the locale setting -which sometimes is useful. + catgets (catdesc, SetOneSet, SetOnetwo, + " Message with ID \"two\", which gets the value 2 assigned") - While for the `LC_xxx' variables the value should consist of exactly -one specification of a locale the `LANGUAGE' variable's value can -consist of a colon separated list of locale names. The attentive -reader will realize that this is the way we manage to implement one of -our additional demands above: we want to be able to specify an ordered -list of language. + Writing the function this way will allow to change the message number +and even the set number without requiring any change in the C source +code. (The text of the string is normally not the same; this is only +for this example.) - Back to the constructed filename we have only one component missing. -The DOMAIN_NAME part is the name which was either registered using the -`textdomain' function or which was given to `dgettext' or `dcgettext' -as the first parameter. Now it becomes obvious that a good choice for -the domain name in the program code is a string which is closely -related to the program/package name. E.g., for the GNU C Library the -domain name is `libc'. +How does to this allow to develop +................................. -A limit piece of example code should show how the programmer is supposed -to work: + To illustrate the usual way to work with the symbolic version numbers +here is a little example. Assume we want to write the very complex and +famous greeting program. We start by writing the code as usual: + #include + int + main (void) { - setlocale (LC_ALL, ""); - textdomain ("test-package"); - bindtextdomain ("test-package", "/usr/local/share/locale"); - puts (gettext ("Hello, world!")); + printf ("Hello, world!\n"); + return 0; } - At the program start the default domain is `messages', and the -default locale is "C". The `setlocale' call sets the locale according -to the user's environment variables; remember that correct functioning -of `gettext' relies on the correct setting of the `LC_MESSAGES' locale -(for looking up the message catalog) and of the `LC_CTYPE' locale (for -the character set conversion). The `textdomain' call changes the -default domain to `test-package'. The `bindtextdomain' call specifies -that the message catalogs for the domain `test-package' can be found -below the directory `/usr/local/share/locale'. - - If now the user set in her/his environment the variable `LANGUAGE' -to `de' the `gettext' function will try to use the translations from -the file - - /usr/local/share/locale/de/LC_MESSAGES/test-package.mo - - From the above descriptions it should be clear which component of -this filename is determined by which source. - - In the above example we assumed that the `LANGUAGE' environment -variable to `de'. This might be an appropriate selection but what -happens if the user wants to use `LC_ALL' because of the wider -usability and here the required value is `de_DE.ISO-8859-1'? We -already mentioned above that a situation like this is not infrequent. -E.g., a person might prefer reading a dialect and if this is not -available fall back on the standard language. - - The `gettext' functions know about situations like this and can -handle them gracefully. The functions recognize the format of the value -of the environment variable. It can split the value is different pieces -and by leaving out the only or the other part it can construct new -values. This happens of course in a predictable way. To understand -this one must know the format of the environment variable value. There -are two more or less standardized forms: - -_X/Open Format_ - `language[_territory[.codeset]][@modifier]' - -_CEN Format (European Community Standard)_ - `language[_territory][+audience][+special][,[sponsor][_revision]]' - - The functions will automatically recognize which format is used. -Less specific locale names will be stripped of in the order of the -following list: - - 1. `revision' - - 2. `sponsor' - - 3. `special' - - 4. `codeset' - - 5. `normalized codeset' - - 6. `territory' - - 7. `audience'/`modifier' - - From the last entry one can see that the meaning of the `modifier' -field in the X/Open format and the `audience' format have the same -meaning. Beside one can see that the `language' field for obvious -reasons never will be dropped. - - The only new thing is the `normalized codeset' entry. This is -another goodie which is introduced to help reducing the chaos which -derives from the inability of the people to standardize the names of -character sets. Instead of ISO-8859-1 one can often see 8859-1, 88591, -iso8859-1, or iso_8859-1. The `normalized codeset' value is generated -from the user-provided character set name by applying the following -rules: + Now we want to internationalize the message and therefore replace the +message with whatever the user wants. - 1. Remove all characters beside numbers and letters. + #include + #include + #include "msgnrs.h" + int + main (void) + { + nl_catd catdesc = catopen ("hello.cat", NL_CAT_LOCALE); + printf (catgets (catdesc, SetMainSet, SetMainHello, + "Hello, world!\n")); + catclose (catdesc); + return 0; + } - 2. Fold letters to lowercase. + We see how the catalog object is opened and the returned descriptor +used in the other function calls. It is not really necessary to check +for failure of any of the functions since even in these situations the +functions will behave reasonable. They simply will be return a +translation. - 3. If the same only contains digits prepend the string `"iso"'. + What remains unspecified here are the constants `SetMainSet' and +`SetMainHello'. These are the symbolic names describing the message. +To get the actual definitions which match the information in the +catalog file we have to create the message catalog source file and +process it using the `gencat' program. -So all of the above name will be normalized to `iso88591'. This allows -the program user much more freely choosing the locale name. + $ Messages for the famous greeting program. + $quote " + + $set Main + Hello "Hallo, Welt!\n" - Even this extended functionality still does not help to solve the -problem that completely different names can be used to denote the same -locale (e.g., `de' and `german'). To be of help in this situation the -locale implementation and also the `gettext' functions know about -aliases. + Now we can start building the program (assume the message catalog +source file is named `hello.msg' and the program source file `hello.c'): - The file `/usr/share/locale/locale.alias' (replace `/usr' with -whatever prefix you used for configuring the C library) contains a -mapping of alternative names to more regular names. The system manager -is free to add new entries to fill her/his own needs. The selected -locale from the environment is compared with the entries in the first -column of this file ignoring the case. If they match the value of the -second column is used instead for the further handling. + % gencat -H msgnrs.h -o hello.cat hello.msg + % cat msgnrs.h + #define MainSet 0x1 /* hello.msg:4 */ + #define MainHello 0x1 /* hello.msg:5 */ + % gcc -o hello hello.c -I. + % cp hello.cat /usr/share/locale/de/LC_MESSAGES + % echo $LC_ALL + de + % ./hello + Hallo, Welt! + % - In the description of the format of the environment variables we -already mentioned the character set as a factor in the selection of the -message catalog. In fact, only catalogs which contain text written -using the character set of the system/program can be used (directly; -there will come a solution for this some day). This means for the user -that s/he will always have to take care for this. If in the collection -of the message catalogs there are files for the same language but coded -using different character sets the user has to be careful. + The call of the `gencat' program creates the missing header file +`msgnrs.h' as well as the message catalog binary. The former is used +in the compilation of `hello.c' while the later is placed in a +directory in which the `catopen' function will try to locate it. +Please check the `LC_ALL' environment variable and the default path for +`catopen' presented in the description above.  -File: libc.info, Node: Helper programs for gettext, Prev: Message catalogs with gettext, Up: The Uniforum approach - -Programs to handle message catalogs for `gettext' -------------------------------------------------- - - The GNU C Library does not contain the source code for the programs -to handle message catalogs for the `gettext' functions. As part of the -GNU project the GNU gettext package contains everything the developer -needs. The functionality provided by the tools in this package by far -exceeds the abilities of the `gencat' program described above for the -`catgets' functions. - - There is a program `msgfmt' which is the equivalent program to the -`gencat' program. It generates from the human-readable and -editable -form of the message catalog a binary file which can be used by the -`gettext' functions. But there are several more programs available. - - The `xgettext' program can be used to automatically extract the -translatable messages from a source file. I.e., the programmer need not -take care for the translations and the list of messages which have to be -translated. S/He will simply wrap the translatable string in calls to -`gettext' et.al and the rest will be done by `xgettext'.

There never was a real standard +defined but still the interface was used in Sun's operation systems. +Since this approach fits better in the development process of free +software it is also used throughout the GNU project and the GNU +`gettext' package provides support for this outside the GNU C Library. -Searching and Sorting -********************* + The code of the `libintl' from GNU `gettext' is the same as the code +in the GNU C Library. So the documentation in the GNU `gettext' manual +is also valid for the functionality here. The following text will +describe the library functions in detail. But the numerous helper +programs are not described in this manual. Instead people should read +the GNU `gettext' manual (*note GNU gettext utilities: (gettext)Top.). +We will only give a short overview. - This chapter describes functions for searching and sorting arrays of -arbitrary objects. You pass the appropriate comparison function to be -applied as an argument, along with the size of the objects in the array -and the total number of elements. + Though the `catgets' functions are available by default on more +systems the `gettext' interface is at least as portable as the former. +The GNU `gettext' package can be used wherever the functions are not +available. * Menu: -* Comparison Functions:: Defining how to compare two objects. - Since the sort and search facilities - are general, you have to specify the - ordering. -* Array Search Function:: The `bsearch' function. -* Array Sort Function:: The `qsort' function. -* Search/Sort Example:: An example program. -* Hash Search Function:: The `hsearch' function. -* Tree Search Function:: The `tsearch' function. +* Message catalogs with gettext:: The `gettext' family of functions. +* Helper programs for gettext:: Programs to handle message catalogs + for `gettext'.  -File: libc.info, Node: Comparison Functions, Next: Array Search Function, Up: Searching and Sorting - -Defining the Comparison Function -================================ - - In order to use the sorted array library functions, you have to -describe how to compare the elements of the array. - - To do this, you supply a comparison function to compare two elements -of the array.

Your comparison function -should return a value the way `strcmp' (*note String/Array -Comparison::) does: negative if the first argument is "less" than the -second, zero if they are "equal", and positive if the first argument is -"greater". +File: libc.info, Node: Message catalogs with gettext, Next: Helper programs for gettext, Up: The Uniforum approach - Here is an example of a comparison function which works with an -array of numbers of type `double': +The `gettext' family of functions +--------------------------------- - int - compare_doubles (const void *a, const void *b) - { - const double *da = (const double *) a; - const double *db = (const double *) b; - - return (*da > *db) - (*da < *db); - } + The paradigms underlying the `gettext' approach to message +translations is different from that of the `catgets' functions the +basic functionally is equivalent.

The GNU C library contains -functions to perform linear search. The prototypes for the following -two functions can be found in `search.h'. - - - Function: void * lfind (const void *KEY, void *BASE, size_t *NMEMB, - size_t SIZE, comparison_fn_t COMPAR) - The `lfind' function searches in the array with `*NMEMB' elements - of SIZE bytes pointed to by BASE for an element which matches the - one pointed to by KEY. The function pointed to by COMPAR is used - decide whether two elements match. - - The return value is a pointer to the matching element in the array - starting at BASE if it is found. If no matching element is - available `NULL' is returned. - - The mean runtime of this function is `*NMEMB'/2. This function - should only be used elements often get added to or deleted from - the array in which case it might not be useful to sort the array - before searching. +File: libc.info, Node: Translation with gettext, Next: Locating gettext catalog, Up: Message catalogs with gettext - - Function: void * lsearch (const void *KEY, void *BASE, size_t - *NMEMB, size_t SIZE, comparison_fn_t COMPAR) - The `lsearch' function is similar to the `lfind' function. It - searches the given array for an element and returns it if found. - The difference is that if no matching element is found the - `lsearch' function adds the object pointed to by KEY (with a size - of SIZE bytes) at the end of the array and it increments the value - of `*NMEMB' to reflect this addition. +What has to be done to translate a message? +........................................... - This means for the caller that if it is not sure that the array - contains the element one is searching for the memory allocated for - the array starting at BASE must have room for at least SIZE more - bytes. If one is sure the element is in the array it is better to - use `lfind' so having more room in the array is always necessary - when calling `lsearch'. + The `gettext' functions have a very simple interface. The most +basic function just takes the string which shall be translated as the +argument and it returns the translation. This is fundamentally +different from the `catgets' approach where an extra key is necessary +and the original string is only used for the error case. - To search a sorted array for an element matching the key, use the -`bsearch' function. The prototype for this function is in the header -file `stdlib.h'. + If the string which has to be translated is the only argument this of +course means the string itself is the key. I.e., the translation will +be selected based on the original string. The message catalogs must +therefore contain the original strings plus one translation for any such +string. The task of the `gettext' function is it to compare the +argument string with the available strings in the catalog and return the +appropriate translation. Of course this process is optimized so that +this process is not more expensive than an access using an atomic key +like in `catgets'. - - Function: void * bsearch (const void *KEY, const void *ARRAY, size_t - COUNT, size_t SIZE, comparison_fn_t COMPARE) - The `bsearch' function searches the sorted array ARRAY for an - object that is equivalent to KEY. The array contains COUNT - elements, each of which is of size SIZE bytes. + The `gettext' approach has some advantages but also some +disadvantages. Please see the GNU `gettext' manual for a detailed +discussion of the pros and cons. - The COMPARE function is used to perform the comparison. This - function is called with two pointer arguments and should return an - integer less than, equal to, or greater than zero corresponding to - whether its first argument is considered less than, equal to, or - greater than its second argument. The elements of the ARRAY must - already be sorted in ascending order according to this comparison - function. + All the definitions and declarations for `gettext' can be found in +the `libintl.h' header file. On systems where these functions are not +part of the C library they can be found in a separate library named +`libintl.a' (or accordingly different for shared libraries). - The return value is a pointer to the matching array element, or a - null pointer if no match is found. If the array contains more - than one element that matches, the one that is returned is - unspecified. + - Function: char * gettext (const char *MSGID) + The `gettext' function searches the currently selected message + catalogs for a string which is equal to MSGID. If there is such a + string available it is returned. Otherwise the argument string + MSGID is returned. - This function derives its name from the fact that it is implemented - using the binary search algorithm. + Please note that all though the return value is `char *' the + returned string must not be changed. This broken type results + from the history of the function and does not reflect the way the + function should be used. - -File: libc.info, Node: Array Sort Function, Next: Search/Sort Example, Prev: Array Search Function, Up: Searching and Sorting + Please note that above we wrote "message catalogs" (plural). This + is a specialty of the GNU implementation of these functions and we + will say more about this when we talk about the ways message + catalogs are selected (*note Locating gettext catalog::). -Array Sort Function -=================== + The `gettext' function does not modify the value of the global + ERRNO variable. This is necessary to make it possible to write + something like - To sort an array using an arbitrary comparison function, use the -`qsort' function. The prototype for this function is in `stdlib.h'. + printf (gettext ("Operation failed: %m\n")); - - Function: void qsort (void *ARRAY, size_t COUNT, size_t SIZE, - comparison_fn_t COMPARE) - The QSORT function sorts the array ARRAY. The array contains - COUNT elements, each of which is of size SIZE. + Here the ERRNO value is used in the `printf' function while + processing the `%m' format element and if the `gettext' function + would change this value (it is called before `printf' is called) + we would get a wrong message. - The COMPARE function is used to perform the comparison on the - array elements. This function is called with two pointer - arguments and should return an integer less than, equal to, or - greater than zero corresponding to whether its first argument is - considered less than, equal to, or greater than its second - argument. + So there is no easy way to detect a missing message catalog beside + comparing the argument string with the result. But it is normally + the task of the user to react on missing catalogs. The program + cannot guess when a message catalog is really necessary since for + a user who speaks the language the program was developed in does + not need any translation. - *Warning:* If two objects compare as equal, their order after - sorting is unpredictable. That is to say, the sorting is not - stable. This can make a difference when the comparison considers - only part of the elements. Two elements with the same sort key - may differ in other respects. + The remaining two functions to access the message catalog add some +functionality to select a message catalog which is not the default one. +This is important if parts of the program are developed independently. +Every part can have its own message catalog and all of them can be used +at the same time. The C library itself is an example: internally it +uses the `gettext' functions but since it must not depend on a +currently selected default message catalog it must specify all ambiguous +information. - If you want the effect of a stable sort, you can get this result by - writing the comparison function so that, lacking other reason - distinguish between two elements, it compares them by their - addresses. Note that doing this may make the sorting algorithm - less efficient, so do it only if necessary. + - Function: char * dgettext (const char *DOMAINNAME, const char *MSGID) + The `dgettext' functions acts just like the `gettext' function. + It only takes an additional first argument DOMAINNAME which guides + the selection of the message catalogs which are searched for the + translation. If the DOMAINNAME parameter is the null pointer the + `dgettext' function is exactly equivalent to `gettext' since the + default value for the domain name is used. - Here is a simple example of sorting an array of doubles in - numerical order, using the comparison function defined above - (*note Comparison Functions::): + As for `gettext' the return value type is `char *' which is an + anachronism. The returned string must never be modified. - { - double *array; - int size; - ... - qsort (array, size, sizeof (double), compare_doubles); - } + - Function: char * dcgettext (const char *DOMAINNAME, const char + *MSGID, int CATEGORY) + The `dcgettext' adds another argument to those which `dgettext' + takes. This argument CATEGORY specifies the last piece of + information needed to localize the message catalog. I.e., the + domain name and the locale category exactly specify which message + catalog has to be used (relative to a given directory, see below). - The `qsort' function derives its name from the fact that it was - originally implemented using the "quick sort" algorithm. + The `dgettext' function can be expressed in terms of `dcgettext' + by using - The implementation of `qsort' in this library might not be an - in-place sort and might thereby use an extra amount of memory to - store the array. + dcgettext (domain, string, LC_MESSAGES) - -File: libc.info, Node: Search/Sort Example, Next: Hash Search Function, Prev: Array Sort Function, Up: Searching and Sorting + instead of -Searching and Sorting Example -============================= + dgettext (domain, string) - Here is an example showing the use of `qsort' and `bsearch' with an -array of structures.

Then, we can look up -individual objects based on their names. + This also shows which values are expected for the third parameter. + One has to use the available selectors for the categories + available in `locale.h'. Normally the available values are + `LC_CTYPE', `LC_COLLATE', `LC_MESSAGES', `LC_MONETARY', + `LC_NUMERIC', and `LC_TIME'.

So it is worth to +optimize this case. Thinking shortly about this one will realize that +as long as no new message catalog is loaded the translation of a message +will not change. This optimization is actually implemented by the +`gettext', `dgettext' and `dcgettext' functions.  -File: libc.info, Node: Hash Search Function, Next: Tree Search Function, Prev: Search/Sort Example, Up: Searching and Sorting - -The `hsearch' function. -======================= +File: libc.info, Node: Locating gettext catalog, Next: Advanced gettext functions, Prev: Translation with gettext, Up: Message catalogs with gettext - The functions mentioned so far in this chapter are searching in a -sorted or unsorted array. There are other methods to organize -information which later should be searched. The costs of insert, -delete and search differ. One possible implementation is using hashing -tables. +How to determine which catalog to be used +......................................... - - Function: int hcreate (size_t NEL) - The `hcreate' function creates a hashing table which can contain at - least NEL elements. There is no possibility to grow this table so - it is necessary to choose the value for NEL wisely. The used - methods to implement this function might make it necessary to make - the number of elements in the hashing table larger than the - expected maximal number of elements. Hashing tables usually work - inefficient if they are filled 80% or more. The constant access - time guaranteed by hashing can only be achieved if few collisions - exist. See Knuth's "The Art of Computer Programming, Part 3: - Searching and Sorting" for more information. + The functions to retrieve the translations for a given message have a +remarkable simple interface. But to provide the user of the program +still the opportunity to select exactly the translation s/he wants and +also to provide the programmer the possibility to influence the way to +locate the search for catalogs files there is a quite complicated +underlying mechanism which controls all this. The code is complicated +the use is easy. - The weakest aspect of this function is that there can be at most - one hashing table used through the whole program. The table is - allocated in local memory out of control of the programmer. As an - extension the GNU C library provides an additional set of - functions with an reentrant interface which provide a similar - interface but which allow to keep arbitrarily many hashing tables. + Basically we have two different tasks to perform which can also be +performed by the `catgets' functions: - It is possible to use more than one hashing table in the program - run if the former table is first destroyed by a call to `hdestroy'. + 1. Locate the set of message catalogs. There are a number of files + for different languages and which all belong to the package. + Usually they are all stored in the filesystem below a certain + directory. - The function returns a non-zero value if successful. If it return - zero something went wrong. This could either mean there is - already a hashing table in use or the program runs out of memory. + There can be arbitrary many packages installed and they can follow + different guidelines for the placement of their files. - - Function: void hdestroy (void) - The `hdestroy' function can be used to free all the resources - allocated in a previous call of `hcreate'. After a call to this - function it is again possible to call `hcreate' and allocate a new - table with possibly different size. + 2. Relative to the location specified by the package the actual + translation files must be searched, based on the wishes of the + user. I.e., for each language the user selects the program should + be able to locate the appropriate file. - It is important to remember that the elements contained in the - hashing table at the time `hdestroy' is called are _not_ freed by - this function. It is the responsibility of the program code to - free those strings (if necessary at all). Freeing all the element - memory is not possible without extra, separately kept information - since there is no function to iterate through all available - elements in the hashing table. If it is really necessary to free - a table and all elements the programmer has to keep a list of all - table elements and before calling `hdestroy' s/he has to free all - element's data using this list. This is a very unpleasant - mechanism and it also shows that this kind of hashing tables is - mainly meant for tables which are created once and used until the - end of the program run. + This is the functionality required by the specifications for +`gettext' and this is also what the `catgets' functions are able to do. +But there are some problems unresolved: - Entries of the hashing table and keys for the search are defined -using this type: + * The language to be used can be specified in several different ways. + There is no generally accepted standard for this and the user + always expects the program understand what s/he means. E.g., to + select the German translation one could write `de', `german', or + `deutsch' and the program should always react the same. - - Data type: struct ENTRY - Both elements of this structure are pointers to zero-terminated - strings. This is a limiting restriction of the functionality of - the `hsearch' functions. They can only be used for data sets - which use the NUL character always and solely to terminate the - records. It is not possible to handle general binary data. + * Sometimes the specification of the user is too detailed. If s/he, + e.g., specifies `de_DE.ISO-8859-1' which means German, spoken in + Germany, coded using the ISO 8859-1 character set there is the + possibility that a message catalog matching this exactly is not + available. But there could be a catalog matching `de' and if the + character set used on the machine is always ISO 8859-1 there is no + reason why this later message catalog should not be used. (We + call this "message inheritance".) - `char *key' - Pointer to a zero-terminated string of characters describing - the key for the search or the element in the hashing table. + * If a catalog for a wanted language is not available it is not + always the second best choice to fall back on the language of the + developer and simply not translate any message. Instead a user + might be better able to read the messages in another language and + so the user of the program should be able to define an precedence + order of languages. - `char *data' - Pointer to a zero-terminated string of characters describing - the data. If the functions will be called only for searching - an existing entry this element might stay undefined since it - is not used. + We can divide the configuration actions in two parts: the one is +performed by the programmer, the other by the user. We will start with +the functions the programmer can use since the user configuration will +be based on this. - - Function: ENTRY * hsearch (ENTRY ITEM, ACTION ACTION) - To search in a hashing table created using `hcreate' the `hsearch' - function must be used. This function can perform simple search - for an element (if ACTION has the `FIND') or it can alternatively - insert the key element into the hashing table, possibly replacing - a previous value (if ACTION is `ENTER'). + As the functions described in the last sections already mention +separate sets of messages can be selected by a "domain name". This is a +simple string which should be unique for each program part with uses a +separate domain. It is possible to use in one program arbitrary many +domains at the same time. E.g., the GNU C Library itself uses a domain +named `libc' while the program using the C Library could use a domain +named `foo'. The important point is that at any time exactly one +domain is active. This is controlled with the following function. - The key is denoted by a pointer to an object of type `ENTRY'. For - locating the corresponding position in the hashing table only the - `key' element of the structure is used. + - Function: char * textdomain (const char *DOMAINNAME) + The `textdomain' function sets the default domain, which is used in + all future `gettext' calls, to DOMAINNAME. Please note that + `dgettext' and `dcgettext' calls are not influenced if the + DOMAINNAME parameter of these functions is not the null pointer. - The return value depends on the ACTION parameter value. If it is - `FIND' the value is a pointer to the matching element in the - hashing table or `NULL' if no matching element exists. If ACTION - is `ENTER' the return value is only `NULL' if the programs runs - out of memory while adding the new element to the table. - Otherwise the return value is a pointer to the element in the - hashing table which contains newly added element based on the data - in KEY. + Before the first call to `textdomain' the default domain is + `messages'. This is the name specified in the specification of + the `gettext' API. This name is as good as any other name. No + program should ever really use a domain with this name since this + can only lead to problems. - As mentioned before the hashing table used by the functions -described so far is global and there can be at any time at most one -hashing table in the program. A solution is to use the following -functions which are a GNU extension. All have in common that they -operate on a hashing table which is described by the content of an -object of the type `struct hsearch_data'. This type should be treated -as opaque, none of its members should be changed directly. + The function returns the value which is from now on taken as the + default domain. If the system went out of memory the returned + value is `NULL' and the global variable ERRNO is set to `ENOMEM'. + Despite the return value type being `char *' the return string must + not be changed. It is allocated internally by the `textdomain' + function. - - Function: int hcreate_r (size_t NEL, struct hsearch_data *HTAB) - The `hcreate_r' function initializes the object pointed to by HTAB - to contain a hashing table with at least NEL elements. So this - function is equivalent to the `hcreate' function except that the - initialized data structure is controlled by the user. + If the DOMAINNAME parameter is the null pointer no new default + domain is set. Instead the currently selected default domain is + returned. - This allows having more than one hashing table at one time. The - memory necessary for the `struct hsearch_data' object can be - allocated dynamically. + If the DOMAINNAME parameter is the empty string the default domain + is reset to its initial value, the domain with the name `messages'. + This possibility is questionable to use since the domain `messages' + really never should be used. - The return value is non-zero if the operation were successful. if - the return value is zero something went wrong which probably means - the programs runs out of memory. + - Function: char * bindtextdomain (const char *DOMAINNAME, const char + *DIRNAME) + The `bindtextdomain' function can be used to specify the directory + which contains the message catalogs for domain DOMAINNAME for the + different languages. To be correct, this is the directory where + the hierarchy of directories is expected. Details are explained + below. - - Function: void hdestroy_r (struct hsearch_data *HTAB) - The `hdestroy_r' function frees all resources allocated by the - `hcreate_r' function for this very same object HTAB. As for - `hdestroy' it is the programs responsibility to free the strings - for the elements of the table. + For the programmer it is important to note that the translations + which come with the program have be placed in a directory + hierarchy starting at, say, `/foo/bar'. Then the program should + make a `bindtextdomain' call to bind the domain for the current + program to this directory. So it is made sure the catalogs are + found. A correctly running program does not depend on the user + setting an environment variable. - - Function: int hsearch_r (ENTRY ITEM, ACTION ACTION, ENTRY **RETVAL, - struct hsearch_data *HTAB) - The `hsearch_r' function is equivalent to `hsearch'. The meaning - of the first two arguments is identical. But instead of operating - on a single global hashing table the function works on the table - described by the object pointed to by HTAB (which is initialized - by a call to `hcreate_r'). + The `bindtextdomain' function can be used several times and if the + DOMAINNAME argument is different the previously bound domains will + not be overwritten. - Another difference to `hcreate' is that the pointer to the found - entry in the table is not the return value of the functions. It is - returned by storing it in a pointer variables pointed to by the - RETVAL parameter. The return value of the function is an integer - value indicating success if it is non-zero and failure if it is - zero. In the latter case the global variable ERRNO signals the - reason for the failure. + If the program which wish to use `bindtextdomain' at some point of + time use the `chdir' function to change the current working + directory it is important that the DIRNAME strings ought to be an + absolute pathname. Otherwise the addressed directory might vary + with the time. - `ENOMEM' - The table is filled and `hsearch_r' was called with an so far - unknown key and ACTION set to `ENTER'. + If the DIRNAME parameter is the null pointer `bindtextdomain' + returns the currently selected directory for the domain with the + name DOMAINNAME. - `ESRCH' - The ACTION parameter is `FIND' and no corresponding element - is found in the table. + The `bindtextdomain' function returns a pointer to a string + containing the name of the selected directory name. The string is + allocated internally in the function and must not be changed by the + user. If the system went out of core during the execution of + `bindtextdomain' the return value is `NULL' and the global + variable ERRNO is set accordingly. diff -durpN glibc-2.2.4/manual/libc.info-14 glibc-2.2.5/manual/libc.info-14 --- glibc-2.2.4/manual/libc.info-14 Mon Aug 13 15:03:42 2001 +++ glibc-2.2.5/manual/libc.info-14 Sun Jan 20 19:28:42 2002 @@ -1,4 +1,4 @@ -This is libc.info, produced by makeinfo version 4.0c from libc.texinfo. +This is libc.info, produced by makeinfo version 4.0 from libc.texinfo.

So it - must not be assumed that the variable pointed to by ROOTP has the - same value after the call.

But if no matching element is - available no new element is entered (note that the ROOTP parameter - points to a constant pointer). Instead the function returns - `NULL'. + The functions of the `gettext' family described so far (and all the +`catgets' functions as well) have one problem in the real world which +have been neglected completely in all existing approaches. What is +meant here is the handling of plural forms. - Another advantage of the `tsearch' function in contrast to the -`hsearch' functions is that there is an easy way to remove elements. + Looking through Unix source code before the time anybody thought +about internationalization (and, sadly, even afterwards) one can often +find code similar to the following: - - Function: void * tdelete (const void *KEY, void **ROOTP, - comparison_fn_t COMPAR) - To remove a specific element matching KEY from the tree `tdelete' - can be used. It locates the matching element using the same - method as `tfind'. The corresponding element is then removed and - a pointer to the parent of the deleted node is returned by the - function. If there is no matching entry in the tree nothing can be - deleted and the function returns `NULL'. If the root of the tree - is deleted `tdelete' returns some unspecified value not equal to - `NULL'. + printf ("%d file%s deleted", n, n == 1 ? "" : "s"); - - Function: void tdestroy (void *VROOT, __free_fn_t FREEFCT) - If the complete search tree has to be removed one can use - `tdestroy'. It frees all resources allocated by the `tsearch' - function to generate the tree pointed to by VROOT. +After the first complaints from people internationalizing the code +people either completely avoided formulations like this or used strings +like `"file(s)"'. Both look unnatural and should be avoided. First +tries to solve the problem correctly looked like this: - For the data in each tree node the function FREEFCT is called. - The pointer to the data is passed as the argument to the function. - If no such work is necessary FREEFCT must point to a function - doing nothing. It is called in any case. + if (n == 1) + printf ("%d file deleted", n); + else + printf ("%d files deleted", n); - This function is a GNU extension and not covered by the System V or - X/Open specifications. + But this does not solve the problem. It helps languages where the +plural form of a noun is not simply constructed by adding an `s' but +that is all. Once again people fell into the trap of believing the +rules their language is using are universal. But the handling of plural +forms differs widely between the language families. There are two +things we can differ between (and even inside language families); - In addition to the function to create and destroy the tree data -structure, there is another function which allows you to apply a -function to all elements of the tree. The function must have this type: + * The form how plural forms are build differs. This is a problem + with language which have many irregularities. German, for + instance, is a drastic case. Though English and German are part + of the same language family (Germanic), the almost regular forming + of plural noun forms (appending an `s') is hardly found in German. - void __action_fn_t (const void *nodep, VISIT value, int level); + * The number of plural forms differ. This is somewhat surprising for + those who only have experiences with Romanic and Germanic languages + since here the number is the same (there are two). - The NODEP is the data value of the current node (once given as the -KEY argument to `tsearch'). LEVEL is a numeric value which corresponds -to the depth of the current node in the tree. The root node has the -depth 0 and its children have a depth of 1 and so on. The `VISIT' type -is an enumeration type. + But other language families have only one form or many forms. More + information on this in an extra section. - - Data Type: VISIT - The `VISIT' value indicates the status of the current node in the - tree and how the function is called. The status of a node is - either `leaf' or `internal node'. For each leaf node the function - is called exactly once, for each internal node it is called three - times: before the first child is processed, after the first child - is processed and after both children are processed. This makes it - possible to handle all three methods of tree traversal (or even a - combination of them). + The consequence of this is that application writers should not try to +solve the problem in their code. This would be localization since it is +only usable for certain, hardcoded language environments. Instead the +extended `gettext' interface should be used. - `preorder' - The current node is an internal node and the function is - called before the first child was processed. + These extra functions are taking instead of the one key string two +strings and an numerical argument. The idea behind this is that using +the numerical argument and the first string as a key, the implementation +can select using rules specified by the translator the right plural +form. The two string arguments then will be used to provide a return +value in case no message catalog is found (similar to the normal +`gettext' behavior). In this case the rules for Germanic language is +used and it is assumed that the first string argument is the singular +form, the second the plural form. - `postorder' - The current node is an internal node and the function is - called after the first child was processed. + This has the consequence that programs without language catalogs can +display the correct strings only if the program itself is written using +a Germanic language. This is a limitation but since the GNU C library +(as well as the GNU `gettext' package) are written as part of the GNU +package and the coding standards for the GNU project require program +being written in English, this solution nevertheless fulfills its +purpose. - `endorder' - The current node is an internal node and the function is - called after the second child was processed. + - Function: char * ngettext (const char *MSGID1, const char *MSGID2, + unsigned long int N) + The `ngettext' function is similar to the `gettext' function as it + finds the message catalogs in the same way. But it takes two + extra arguments. The MSGID1 parameter must contain the singular + form of the string to be converted. It is also used as the key + for the search in the catalog. The MSGID2 parameter is the plural + form. The parameter N is used to determine the plural form. If no + message catalog is found MSGID1 is returned if `n == 1', otherwise + `msgid2'. - `leaf' - The current node is a leaf. + An example for the us of this function is: - - Function: void twalk (const void *ROOT, __action_fn_t ACTION) - For each node in the tree with a node pointed to by ROOT, the - `twalk' function calls the function provided by the parameter - ACTION. For leaf nodes the function is called exactly once with - VALUE set to `leaf'. For internal nodes the function is called - three times, setting the VALUE parameter or ACTION to the - appropriate value. The LEVEL argument for the ACTION function is - computed while descending the tree with increasing the value by - one for the descend to a child, starting with the value 0 for the - root node. + printf (ngettext ("%d file removed", "%d files removed", n), n); - Since the functions used for the ACTION parameter to `twalk' must - not modify the tree data, it is safe to run `twalk' in more than - one thread at the same time, working on the same tree. It is also - safe to call `tfind' in parallel. Functions which modify the tree - must not be used, otherwise the behavior is undefined. + Please note that the numeric value N has to be passed to the + `printf' function as well. It is not sufficient to pass it only to + `ngettext'. - -File: libc.info, Node: Pattern Matching, Next: I/O Overview, Prev: Searching and Sorting, Up: Top + - Function: char * dngettext (const char *DOMAIN, const char *MSGID1, + const char *MSGID2, unsigned long int N) + The `dngettext' is similar to the `dgettext' function in the way + the message catalog is selected.

The library -also provides a facility for expanding variable and command references -and parsing text into words in the way the shell does. +The problem of plural forms +........................... -* Menu: + A description of the problem can be found at the beginning of the +last section. Now there is the question how to solve it. Without the +input of linguists (which was not available) it was not possible to +determine whether there are only a few different forms in which plural +forms are formed or whether the number can increase with every new +supported language. -* Wildcard Matching:: Matching a wildcard pattern against a single string. -* Globbing:: Finding the files that match a wildcard pattern. -* Regular Expressions:: Matching regular expressions against strings. -* Word Expansion:: Expanding shell variables, nested commands, - arithmetic, and wildcards. - This is what the shell does with shell commands. + Therefore the solution implemented is to allow the translator to +specify the rules of how to select the plural form. Since the formula +varies with every language this is the only viable solution except for +hardcoding the information in the code (which still would require the +possibility of extensions to not prevent the use of new languages). The +details are explained in the GNU `gettext' manual. Here only a a bit +of information is provided. - -File: libc.info, Node: Wildcard Matching, Next: Globbing, Up: Pattern Matching + The information about the plural form selection has to be stored in +the header entry (the one with the empty (`msgid' string). It looks +like this: -Wildcard Matching -================= + Plural-Forms: nplurals=2; plural=n == 1 ? 0 : 1; - This section describes how to match a wildcard pattern against a -particular string. The result is a yes or no answer: does the string -fit the pattern or not. The symbols described here are all declared in -`fnmatch.h'. + The `nplurals' value must be a decimal number which specifies how +many different plural forms exist for this language. The string +following `plural' is an expression which is using the C language +syntax. Exceptions are that no negative number are allowed, numbers +must be decimal, and the only variable allowed is `n'. This expression +will be evaluated whenever one of the functions `ngettext', +`dngettext', or `dcngettext' is called. The numeric value passed to +these functions is then substituted for all uses of the variable `n' in +the expression. The resulting value then must be greater or equal to +zero and smaller than the value given as the value of `nplurals'. - - Function: int fnmatch (const char *PATTERN, const char *STRING, int - FLAGS) - This function tests whether the string STRING matches the pattern - PATTERN.

More precisely, - it records both the address of the word vector and its size. The - GNU implementation contains some more fields which are non-standard - extensions. + `gettext' not only looks up a translation in a message catalog. It +also converts the translation on the fly to the desired output character +set. This is useful if the user is working in a different character set +than the translator who created the message catalog, because it avoids +distributing variants of message catalogs which differ only in the +character set. - `gl_pathc' - The number of elements in the vector, excluding the initial - null entries if the GLOB_DOOFFS flag is used (see gl_offs - below). + The output character set is, by default, the value of `nl_langinfo +(CODESET)', which depends on the `LC_CTYPE' part of the current locale. +But programs which store strings in a locale independent way (e.g. +UTF-8) can request that `gettext' and related functions return the +translations in that encoding, by use of the `bind_textdomain_codeset' +function. - `gl_pathv' - The address of the vector. This field has type `char **'. + Note that the MSGID argument to `gettext' is not subject to +character set conversion. Also, when `gettext' does not find a +translation for MSGID, it returns MSGID unchanged - independently of +the current output character set. It is therefore recommended that all +MSGIDs be US-ASCII strings. - `gl_offs' - The offset of the first real element of the vector, from its - nominal address in the `gl_pathv' field. Unlike the other - fields, this is always an input to `glob', rather than an - output from it. + - Function: char * bind_textdomain_codeset (const char *DOMAINNAME, + const char *CODESET) + The `bind_textdomain_codeset' function can be used to specify the + output character set for message catalogs for domain DOMAINNAME. + The CODESET argument must be a valid codeset name which can be used + for the `iconv_open' function, or a null pointer. - If you use a nonzero offset, then that many elements at the - beginning of the vector are left empty.

Otherwise, the offset is always zero - regardless of what is in this field, and the first real - element comes at the beginning of the vector. + The `bind_textdomain_codeset' function can be used several times. + If used multiple times with the same DOMAINNAME argument, the + later call overrides the settings made by the earlier one. - `gl_closedir' - The address of an alternative implementation of the `closedir' - function.

The +problem is that many of the strings which have to be translated are very +short. They have to appear in pull-down menus which restricts the +length. But strings which are not containing entire sentences or at +least large fragments of a sentence may appear in more than one +situation in the program but might have different translations. This is +especially true for the one-word strings which are frequently used in +GUI programs. - `gl_opendir' - The address of an alternative implementation of the `opendir' - function. It is used if the `GLOB_ALTDIRFUNC' bit is set in - the flag parameter. The type of this field is - `void *(*) (const char *)'. + As a consequence many people say that the `gettext' approach is +wrong and instead `catgets' should be used which indeed does not have +this problem. But there is a very simple and powerful method to handle +these kind of problems with the `gettext' functions. - This is a GNU extension. +As as example consider the following fictional situation. A GUI program +has a menu bar with the following entries: - `gl_stat' - The address of an alternative implementation of the `stat64' - function to get information about an object in the - filesystem. It is used if the `GLOB_ALTDIRFUNC' bit is set - in the flag parameter. The type of this field is - `int (*) (const char *, struct stat64 *)'. + +------------+------------+--------------------------------------+ + | File | Printer | | + +------------+------------+--------------------------------------+ + | Open | | Select | + | New | | Open | + +----------+ | Connect | + +----------+ - This is a GNU extension. + To have the strings `File', `Printer', `Open', `New', `Select', and +`Connect' translated there has to be at some point in the code a call +to a function of the `gettext' family. But in two places the string +passed into the function would be `Open'. The translations might not +be the same and therefore we are in the dilemma described above. - `gl_lstat' - The address of an alternative implementation of the `lstat64' - function to get information about an object in the - filesystems, not following symbolic links. It is used if the - `GLOB_ALTDIRFUNC' bit is set in the flag parameter. The type - of this field is `int (*) (const char *, struct stat64 *)'. + One solution to this problem is to artificially enlengthen the +strings to make them unambiguous. But what would the program do if no +translation is available? The enlengthened string is not what should be +printed. So we should use a little bit modified version of the +functions. - This is a GNU extension. + To enlengthen the strings a uniform method should be used. E.g., in +the example above the strings could be chosen as - - Function: int glob (const char *PATTERN, int FLAGS, int (*ERRFUNC) - (const char *FILENAME, int ERROR-CODE), glob_t *VECTOR-PTR) - The function `glob' does globbing using the pattern PATTERN in the - current directory. It puts the result in a newly allocated - vector, and stores the size and address of this vector into - `*VECTOR-PTR'. The argument FLAGS is a combination of bit flags; - see *Note Flags for Globbing::, for details of the flags. + Menu|File + Menu|Printer + Menu|File|Open + Menu|File|New + Menu|Printer|Select + Menu|Printer|Open + Menu|Printer|Connect - The result of globbing is a sequence of file names. The function - `glob' allocates a string for each resulting word, then allocates - a vector of type `char **' to store the addresses of these - strings. The last element of the vector is a null pointer. This - vector is called the "word vector". + Now all the strings are different and if now instead of `gettext' +the following little wrapper function is used, everything works just +fine: - To return this vector, `glob' stores both its address and its - length (number of elements, not counting the terminating null - pointer) into `*VECTOR-PTR'. + char * + sgettext (const char *msgid) + { + char *msgval = gettext (msgid); + if (msgval == msgid) + msgval = strrchr (msgid, '|') + 1; + return msgval; + } - Normally, `glob' sorts the file names alphabetically before - returning them. You can turn this off with the flag `GLOB_NOSORT' - if you want to get the information as fast as possible. Usually - it's a good idea to let `glob' sort them--if you process the files - in alphabetical order, the users will have a feel for the rate of - progress that your application is making. + What this little function does is to recognize the case when no +translation is available. This can be done very efficiently by a +pointer comparison since the return value is the input value. If there +is no translation we know that the input string is in the format we used +for the Menu entries and therefore contains a `|' character. We simply +search for the last occurrence of this character and return a pointer +to the character following it. That's it! - If `glob' succeeds, it returns 0. Otherwise, it returns one of - these error codes: + If one now consistently uses the enlengthened string form and +replaces the `gettext' calls with calls to `sgettext' (this is normally +limited to very few places in the GUI implementation) then it is +possible to produce a program which can be internationalized. - `GLOB_ABORTED' - There was an error opening a directory, and you used the flag - `GLOB_ERR' or your specified ERRFUNC returned a nonzero value. - *Note Flags for Globbing::, for an explanation of the - `GLOB_ERR' flag and ERRFUNC. + With advanced compilers (such as GNU C) one can write the `sgettext' +functions as an inline function or as a macro like this: - `GLOB_NOMATCH' - The pattern didn't match any existing files. If you use the - `GLOB_NOCHECK' flag, then you never get this error code, - because that flag tells `glob' to _pretend_ that the pattern - matched at least one file. + #define sgettext(msgid) \ + ({ const char *__msgid = (msgid); \ + char *__msgstr = gettext (__msgid); \ + if (__msgval == __msgid) \ + __msgval = strrchr (__msgid, '|') + 1; \ + __msgval; }) - `GLOB_NOSPACE' - It was impossible to allocate memory to hold the result. + The other `gettext' functions (`dgettext', `dcgettext' and the +`ngettext' equivalents) can and should have corresponding functions as +well which look almost identical, except for the parameters and the +call to the underlying function. - In the event of an error, `glob' stores information in - `*VECTOR-PTR' about all the matches it has found so far. + Now there is of course the question why such functions do not exist +in the GNU C library? There are two parts of the answer to this +question. - It is important to notice that the `glob' function will not fail if - it encounters directories or files which cannot be handled without - the LFS interfaces. The implementation of `glob' is supposed to - use these functions internally. This at least is the assumptions - made by the Unix standard. The GNU extension of allowing the user - to provide own directory handling and `stat' functions complicates - things a bit. If these callback functions are used and a large - file or directory is encountered `glob' _can_ fail. + * They are easy to write and therefore can be provided by the + project they are used in. This is not an answer by itself and + must be seen together with the second part which is: - - Function: int glob64 (const char *PATTERN, int FLAGS, int (*ERRFUNC) - (const char *FILENAME, int ERROR-CODE), glob64_t *VECTOR-PTR) - The `glob64' function was added as part of the Large File Summit - extensions but is not part of the original LFS proposal. The - reason for this is simple: it is not necessary. The necessity for - a `glob64' function is added by the extensions of the GNU `glob' - implementation which allows the user to provide own directory - handling and `stat' functions. The `readdir' and `stat' functions - do depend on the choice of `_FILE_OFFSET_BITS' since the definition - of the types `struct dirent' and `struct stat' will change - depending on the choice. + * There is no way the C library can contain a version which can work + everywhere. The problem is the selection of the character to + separate the prefix from the actual string in the enlenghtened + string. The examples above used `|' which is a quite good choice + because it resembles a notation frequently used in this context + and it also is a character not often used in message strings. - Beside this difference the `glob64' works just like `glob' in all - aspects. + But what if the character is used in message strings. Or if the + chose character is not available in the character set on the + machine one compiles (e.g., `|' is not required to exist for + ISO C; this is why the `iso646.h' file exists in ISO C programming + environments). - This function is a GNU extension. + There is only one more comment to make left. The wrapper function +above require that the translations strings are not enlengthened +themselves. This is only logical. There is no need to disambiguate +the strings (since they are never used as keys for a search) and one +also saves quite some memory and disk space by doing this.  -File: libc.info, Node: Flags for Globbing, Next: More Flags for Globbing, Prev: Calling Glob, Up: Globbing +File: libc.info, Node: Using gettextized software, Prev: GUI program problems, Up: Message catalogs with gettext -Flags for Globbing ------------------- +User influence on `gettext' +........................... - This section describes the flags that you can specify in the FLAGS -argument to `glob'. Choose the flags you want, and combine them with -the C bitwise OR operator `|'. + The last sections described what the programmer can do to +internationalize the messages of the program. But it is finally up to +the user to select the message s/he wants to see. S/He must understand +them. -`GLOB_APPEND' - Append the words from this expansion to the vector of words - produced by previous calls to `glob'. This way you can - effectively expand several words as if they were concatenated with - spaces between them. + The POSIX locale model uses the environment variables `LC_COLLATE', +`LC_CTYPE', `LC_MESSAGES', `LC_MONETARY', `NUMERIC', and `LC_TIME' to +select the locale which is to be used. This way the user can influence +lots of functions. As we mentioned above the `gettext' functions also +take advantage of this. - In order for appending to work, you must not modify the contents - of the word vector structure between calls to `glob'. And, if you - set `GLOB_DOOFFS' in the first call to `glob', you must also set - it when you append to the results. + To understand how this happens it is necessary to take a look at the +various components of the filename which gets computed to locate a +message catalog. It is composed as follows: - Note that the pointer stored in `gl_pathv' may no longer be valid - after you call `glob' the second time, because `glob' might have - relocated the vector. So always fetch `gl_pathv' from the - `glob_t' structure after each `glob' call; *never* save the - pointer across calls. + DIR_NAME/LOCALE/LC_CATEGORY/DOMAIN_NAME.mo -`GLOB_DOOFFS' - Leave blank slots at the beginning of the vector of words. The - `gl_offs' field says how many slots to leave. The blank slots - contain null pointers. + The default value for DIR_NAME is system specific. It is computed +from the value given as the prefix while configuring the C library. +This value normally is `/usr' or `/'. For the former the complete +DIR_NAME is: -`GLOB_ERR' - Give up right away and report an error if there is any difficulty - reading the directories that must be read in order to expand - PATTERN fully. Such difficulties might include a directory in - which you don't have the requisite access. Normally, `glob' tries - its best to keep on going despite any errors, reading whatever - directories it can. + /usr/share/locale - You can exercise even more control than this by specifying an - error-handler function ERRFUNC when you call `glob'. If ERRFUNC - is not a null pointer, then `glob' doesn't give up right away when - it can't read a directory; instead, it calls ERRFUNC with two - arguments, like this: + We can use `/usr/share' since the `.mo' files containing the message +catalogs are system independent, so all systems can use the same files. +If the program executed the `bindtextdomain' function for the message +domain that is currently handled, the `dir_name' component is exactly +the value which was given to the function as the second parameter. +I.e., `bindtextdomain' allows overwriting the only system dependent and +fixed value to make it possible to address files anywhere in the +filesystem. - (*ERRFUNC) (FILENAME, ERROR-CODE) + The CATEGORY is the name of the locale category which was selected +in the program code. For `gettext' and `dgettext' this is always +`LC_MESSAGES', for `dcgettext' this is selected by the value of the +third parameter. As said above it should be avoided to ever use a +category other than `LC_MESSAGES'. - The argument FILENAME is the name of the directory that `glob' - couldn't open or couldn't read, and ERROR-CODE is the `errno' - value that was reported to `glob'. + The LOCALE component is computed based on the category used. Just +like for the `setlocale' function here comes the user selection into +the play. Some environment variables are examined in a fixed order and +the first environment variable set determines the return value of the +lookup process. In detail, for the category `LC_xxx' the following +variables in this order are examined: - If the error handler function returns nonzero, then `glob' gives up - right away. Otherwise, it continues. +`LANGUAGE' -`GLOB_MARK' - If the pattern matches the name of a directory, append `/' to the - directory's name when returning it. +`LC_ALL' -`GLOB_NOCHECK' - If the pattern doesn't match any file names, return the pattern - itself as if it were a file name that had been matched. - (Normally, when the pattern doesn't match anything, `glob' returns - that there were no matches.) +`LC_xxx' -`GLOB_NOSORT' - Don't sort the file names; return them in no particular order. - (In practice, the order will depend on the order of the entries in - the directory.) The only reason _not_ to sort is to save time. +`LANG' + This looks very familiar. With the exception of the `LANGUAGE' +environment variable this is exactly the lookup order the `setlocale' +function uses. But why introducing the `LANGUAGE' variable? -`GLOB_NOESCAPE' - Don't treat the `\' character specially in patterns. Normally, - `\' quotes the following character, turning off its special meaning - (if any) so that it matches only itself. When quoting is enabled, - the pattern `\?' matches only the string `?', because the question - mark in the pattern acts like an ordinary character. + The reason is that the syntax of the values these variables can have +is different to what is expected by the `setlocale' function. If we +would set `LC_ALL' to a value following the extended syntax that would +mean the `setlocale' function will never be able to use the value of +this variable as well. An additional variable removes this problem +plus we can select the language independently of the locale setting +which sometimes is useful. - If you use `GLOB_NOESCAPE', then `\' is an ordinary character. + While for the `LC_xxx' variables the value should consist of exactly +one specification of a locale the `LANGUAGE' variable's value can +consist of a colon separated list of locale names. The attentive +reader will realize that this is the way we manage to implement one of +our additional demands above: we want to be able to specify an ordered +list of language. - `glob' does its work by calling the function `fnmatch' repeatedly. - It handles the flag `GLOB_NOESCAPE' by turning on the - `FNM_NOESCAPE' flag in calls to `fnmatch'. + Back to the constructed filename we have only one component missing. +The DOMAIN_NAME part is the name which was either registered using the +`textdomain' function or which was given to `dgettext' or `dcgettext' +as the first parameter. Now it becomes obvious that a good choice for +the domain name in the program code is a string which is closely +related to the program/package name. E.g., for the GNU C Library the +domain name is `libc'. - -File: libc.info, Node: More Flags for Globbing, Prev: Flags for Globbing, Up: Globbing +A limit piece of example code should show how the programmer is supposed +to work: -More Flags for Globbing ------------------------ + { + setlocale (LC_ALL, ""); + textdomain ("test-package"); + bindtextdomain ("test-package", "/usr/local/share/locale"); + puts (gettext ("Hello, world!")); + } - Beside the flags described in the last section, the GNU -implementation of `glob' allows a few more flags which are also defined -in the `glob.h' file. Some of the extensions implement functionality -which is available in modern shell implementations. + At the program start the default domain is `messages', and the +default locale is "C". The `setlocale' call sets the locale according +to the user's environment variables; remember that correct functioning +of `gettext' relies on the correct setting of the `LC_MESSAGES' locale +(for looking up the message catalog) and of the `LC_CTYPE' locale (for +the character set conversion). The `textdomain' call changes the +default domain to `test-package'. The `bindtextdomain' call specifies +that the message catalogs for the domain `test-package' can be found +below the directory `/usr/local/share/locale'. -`GLOB_PERIOD' - The `.' character (period) is treated special. It cannot be - matched by wildcards. *Note Wildcard Matching::, `FNM_PERIOD'. + If now the user set in her/his environment the variable `LANGUAGE' +to `de' the `gettext' function will try to use the translations from +the file -`GLOB_MAGCHAR' - The `GLOB_MAGCHAR' value is not to be given to `glob' in the FLAGS - parameter. Instead, `glob' sets this bit in the GL_FLAGS element - of the GLOB_T structure provided as the result if the pattern used - for matching contains any wildcard character. + /usr/local/share/locale/de/LC_MESSAGES/test-package.mo -`GLOB_ALTDIRFUNC' - Instead of the using the using the normal functions for accessing - the filesystem the `glob' implementation uses the user-supplied - functions specified in the structure pointed to by PGLOB - parameter. For more information about the functions refer to the - sections about directory handling see *Note Accessing - Directories::, and *Note Reading Attributes::. + From the above descriptions it should be clear which component of +this filename is determined by which source. -`GLOB_BRACE' - If this flag is given the handling of braces in the pattern is - changed. It is now required that braces appear correctly grouped. - I.e., for each opening brace there must be a closing one. Braces - can be used recursively. So it is possible to define one brace - expression in another one. It is important to note that the range - of each brace expression is completely contained in the outer - brace expression (if there is one). + In the above example we assumed that the `LANGUAGE' environment +variable to `de'. This might be an appropriate selection but what +happens if the user wants to use `LC_ALL' because of the wider +usability and here the required value is `de_DE.ISO-8859-1'? We +already mentioned above that a situation like this is not infrequent. +E.g., a person might prefer reading a dialect and if this is not +available fall back on the standard language. - The string between the matching braces is separated into single - expressions by splitting at `,' (comma) characters. The commas - themselves are discarded. Please note what we said above about - recursive brace expressions. The commas used to separate the - subexpressions must be at the same level. Commas in brace - subexpressions are not matched. They are used during expansion of - the brace expression of the deeper level. The example below shows - this + The `gettext' functions know about situations like this and can +handle them gracefully. The functions recognize the format of the value +of the environment variable. It can split the value is different pieces +and by leaving out the only or the other part it can construct new +values. This happens of course in a predictable way. To understand +this one must know the format of the environment variable value. There +are two more or less standardized forms: - glob ("{foo/{,bar,biz},baz}", GLOB_BRACE, NULL, &result) +_X/Open Format_ + `language[_territory[.codeset]][@modifier]' - is equivalent to the sequence +_CEN Format (European Community Standard)_ + `language[_territory][+audience][+special][,[sponsor][_revision]]' - glob ("foo/", GLOB_BRACE, NULL, &result) - glob ("foo/bar", GLOB_BRACE|GLOB_APPEND, NULL, &result) - glob ("foo/biz", GLOB_BRACE|GLOB_APPEND, NULL, &result) - glob ("baz", GLOB_BRACE|GLOB_APPEND, NULL, &result) + The functions will automatically recognize which format is used. +Less specific locale names will be stripped of in the order of the +following list: - if we leave aside error handling. + 1. `revision' -`GLOB_NOMAGIC' - If the pattern contains no wildcard constructs (it is a literal - file name), return it as the sole "matching" word, even if no file - exists by that name. + 2. `sponsor' -`GLOB_TILDE' - If this flag is used the character `~' (tilde) is handled special - if it appears at the beginning of the pattern. Instead of being - taken verbatim it is used to represent the home directory of a - known user. + 3. `special' - If `~' is the only character in pattern or it is followed by a `/' - (slash), the home directory of the process owner is substituted. - Using `getlogin' and `getpwnam' the information is read from the - system databases. As an example take user `bart' with his home - directory at `/home/bart'. For him a call like + 4. `codeset' - glob ("~/bin/*", GLOB_TILDE, NULL, &result) + 5. `normalized codeset' - would return the contents of the directory `/home/bart/bin'. - Instead of referring to the own home directory it is also possible - to name the home directory of other users. To do so one has to - append the user name after the tilde character. So the contents - of user `homer''s `bin' directory can be retrieved by + 6. `territory' - glob ("~homer/bin/*", GLOB_TILDE, NULL, &result) + 7. `audience'/`modifier' - If the user name is not valid or the home directory cannot be - determined for some reason the pattern is left untouched and - itself used as the result. I.e., if in the last example `home' is - not available the tilde expansion yields to `"~homer/bin/*"' and - `glob' is not looking for a directory named `~homer'. + From the last entry one can see that the meaning of the `modifier' +field in the X/Open format and the `audience' format have the same +meaning. Beside one can see that the `language' field for obvious +reasons never will be dropped. - This functionality is equivalent to what is available in C-shells - if the `nonomatch' flag is set. + The only new thing is the `normalized codeset' entry. This is +another goodie which is introduced to help reducing the chaos which +derives from the inability of the people to standardize the names of +character sets. Instead of ISO-8859-1 one can often see 8859-1, 88591, +iso8859-1, or iso_8859-1. The `normalized codeset' value is generated +from the user-provided character set name by applying the following +rules: -`GLOB_TILDE_CHECK' - If this flag is used `glob' behaves like as if `GLOB_TILDE' is - given. The only difference is that if the user name is not - available or the home directory cannot be determined for other - reasons this leads to an error. `glob' will return `GLOB_NOMATCH' - instead of using the pattern itself as the name. + 1. Remove all characters beside numbers and letters. - This functionality is equivalent to what is available in C-shells - if `nonomatch' flag is not set. + 2. Fold letters to lowercase. -`GLOB_ONLYDIR' - If this flag is used the globbing function takes this as a *hint* - that the caller is only interested in directories matching the - pattern. If the information about the type of the file is easily - available non-directories will be rejected but no extra work will - be done to determine the information for each file. I.e., the - caller must still be able to filter directories out. + 3. If the same only contains digits prepend the string `"iso"'. - This functionality is only available with the GNU `glob' - implementation. It is mainly used internally to increase the - performance but might be useful for a user as well and therefore is - documented here. +So all of the above name will be normalized to `iso88591'.

This is not true compilation--it produces a special data -structure, not machine instructions. But it is like ordinary -compilation in that its purpose is to enable you to "execute" the -pattern fast. (*Note Matching POSIX Regexps::, for how to use the -compiled regular expression for matching.) - - There is a special data type for compiled regular expressions: - - - Data Type: regex_t - This type of object holds a compiled regular expression. It is - actually a structure. It has just one field that your programs - should look at: - - `re_nsub' - This field holds the number of parenthetical subexpressions - in the regular expression that was compiled. - - There are several other fields, but we don't describe them here, - because only the functions in the library should use them. - - After you create a `regex_t' object, you can compile a regular -expression into it by calling `regcomp'. - - - Function: int regcomp (regex_t *COMPILED, const char *PATTERN, int - CFLAGS) - The function `regcomp' "compiles" a regular expression into a data - structure that you can use with `regexec' to match against a - string. The compiled regular expression format is designed for - efficient matching. `regcomp' stores it into `*COMPILED'. - - It's up to you to allocate an object of type `regex_t' and pass its - address to `regcomp'. - - The argument CFLAGS lets you specify various options that control - the syntax and semantics of regular expressions. *Note Flags for - POSIX Regexps::. - - If you use the flag `REG_NOSUB', then `regcomp' omits from the - compiled regular expression the information necessary to record - how subexpressions actually match. In this case, you might as well - pass `0' for the MATCHPTR and NMATCH arguments when you call - `regexec'. - - If you don't use `REG_NOSUB', then the compiled regular expression - does have the capacity to record how subexpressions match. Also, - `regcomp' tells you how many subexpressions PATTERN has, by - storing the number in `COMPILED->re_nsub'. You can use that value - to decide how long an array to allocate to hold information about - subexpression matches. - - `regcomp' returns `0' if it succeeds in compiling the regular - expression; otherwise, it returns a nonzero error code (see the - table below). You can use `regerror' to produce an error message - string describing the reason for a nonzero value; see *Note Regexp - Cleanup::. - - - Here are the possible nonzero values that `regcomp' can return: - -`REG_BADBR' - There was an invalid `\{...\}' construct in the regular - expression.

This function is called with two pointer + arguments and should return an integer less than, equal to, or + greater than zero corresponding to whether its first argument is + considered less than, equal to, or greater than its second + argument. - Sometimes a subexpression matches a substring of no characters. This -happens when `f\(o*\)' matches the string `fum'. (It really matches -just the `f'.) In this case, both of the offsets identify the point in -the string where the null substring was found. In this example, the -offsets are both `1'. + *Warning:* If two objects compare as equal, their order after + sorting is unpredictable. That is to say, the sorting is not + stable. This can make a difference when the comparison considers + only part of the elements. Two elements with the same sort key + may differ in other respects. - Sometimes the entire regular expression can match without using some -of its subexpressions at all--for example, when `ba\(na\)*' matches the -string `ba', the parenthetical subexpression is not used. When this -happens, `regexec' stores `-1' in both fields of the element for that -subexpression. + If you want the effect of a stable sort, you can get this result by + writing the comparison function so that, lacking other reason + distinguish between two elements, it compares them by their + addresses. Note that doing this may make the sorting algorithm + less efficient, so do it only if necessary. - Sometimes matching the entire regular expression can match a -particular subexpression more than once--for example, when `ba\(na\)*' -matches the string `bananana', the parenthetical subexpression matches -three times. When this happens, `regexec' usually stores the offsets -of the last part of the string that matched the subexpression. In the -case of `bananana', these offsets are `6' and `8'. + Here is a simple example of sorting an array of doubles in + numerical order, using the comparison function defined above + (*note Comparison Functions::): - But the last match is not always the one that is chosen. It's more -accurate to say that the last _opportunity_ to match is the one that -takes precedence. What this means is that when one subexpression -appears within another, then the results reported for the inner -subexpression reflect whatever happened on the last match of the outer -subexpression. For an example, consider `\(ba\(na\)*s \)*' matching -the string `bananas bas '. The last time the inner expression actually -matches is near the end of the first word. But it is _considered_ -again in the second word, and fails to match there. `regexec' reports -nonuse of the "na" subexpression. + { + double *array; + int size; + ... + qsort (array, size, sizeof (double), compare_doubles); + } - Another place where this rule applies is when the regular expression - \(ba\(na\)*s \|nefer\(ti\)* \)* + The `qsort' function derives its name from the fact that it was + originally implemented using the "quick sort" algorithm. -matches `bananas nefertiti'. The "na" subexpression does match in the -first word, but it doesn't match in the second word because the other -alternative is used there. Once again, the second repetition of the -outer subexpression overrides the first, and within that second -repetition, the "na" subexpression is not used. So `regexec' reports -nonuse of the "na" subexpression. + The implementation of `qsort' in this library might not be an + in-place sort and might thereby use an extra amount of memory to + store the array.  -File: libc.info, Node: Regexp Cleanup, Prev: Subexpression Complications, Up: Regular Expressions - -POSIX Regexp Matching Cleanup ------------------------------ - - When you are finished using a compiled regular expression, you can -free the storage it uses by calling `regfree'. +File: libc.info, Node: Search/Sort Example, Next: Hash Search Function, Prev: Array Sort Function, Up: Searching and Sorting - - Function: void regfree (regex_t *COMPILED) - Calling `regfree' frees all the storage that `*COMPILED' points - to.

This could either mean there is + already a hashing table in use or the program runs out of memory. - For example, when you write `ls -l foo.c', this string is split into -three separate words--`ls', `-l' and `foo.c'. This is the most basic -function of word expansion. + - Function: void hdestroy (void) + The `hdestroy' function can be used to free all the resources + allocated in a previous call of `hcreate'. After a call to this + function it is again possible to call `hcreate' and allocate a new + table with possibly different size. - When you write `ls *.c', this can become many words, because the -word `*.c' can be replaced with any number of file names. This is -called "wildcard expansion", and it is also a part of word expansion. + It is important to remember that the elements contained in the + hashing table at the time `hdestroy' is called are _not_ freed by + this function. It is the responsibility of the program code to + free those strings (if necessary at all). Freeing all the element + memory is not possible without extra, separately kept information + since there is no function to iterate through all available + elements in the hashing table. If it is really necessary to free + a table and all elements the programmer has to keep a list of all + table elements and before calling `hdestroy' s/he has to free all + element's data using this list. This is a very unpleasant + mechanism and it also shows that this kind of hashing tables is + mainly meant for tables which are created once and used until the + end of the program run. - When you use `echo $PATH' to print your path, you are taking -advantage of "variable substitution", which is also part of word -expansion. + Entries of the hashing table and keys for the search are defined +using this type: - Ordinary programs can perform word expansion just like the shell by -calling the library function `wordexp'. + - Data type: struct ENTRY + Both elements of this structure are pointers to zero-terminated + strings.

This function can perform simple search + for an element (if ACTION has the `FIND') or it can alternatively + insert the key element into the hashing table, possibly replacing + a previous value (if ACTION is `ENTER'). -The Stages of Word Expansion ----------------------------- + The key is denoted by a pointer to an object of type `ENTRY'. For + locating the corresponding position in the hashing table only the + `key' element of the structure is used. - When word expansion is applied to a sequence of words, it performs -the following transformations in the order shown here: + The return value depends on the ACTION parameter value. If it is + `FIND' the value is a pointer to the matching element in the + hashing table or `NULL' if no matching element exists. If ACTION + is `ENTER' the return value is only `NULL' if the programs runs + out of memory while adding the new element to the table. + Otherwise the return value is a pointer to the element in the + hashing table which contains newly added element based on the data + in KEY. - 1. "Tilde expansion": Replacement of `~foo' with the name of the home - directory of `foo'. + As mentioned before the hashing table used by the functions +described so far is global and there can be at any time at most one +hashing table in the program. A solution is to use the following +functions which are a GNU extension. All have in common that they +operate on a hashing table which is described by the content of an +object of the type `struct hsearch_data'. This type should be treated +as opaque, none of its members should be changed directly. - 2. Next, three different transformations are applied in the same step, - from left to right: + - Function: int hcreate_r (size_t NEL, struct hsearch_data *HTAB) + The `hcreate_r' function initializes the object pointed to by HTAB + to contain a hashing table with at least NEL elements. So this + function is equivalent to the `hcreate' function except that the + initialized data structure is controlled by the user. - * "Variable substitution": Environment variables are - substituted for references such as `$foo'. + This allows having more than one hashing table at one time. The + memory necessary for the `struct hsearch_data' object can be + allocated dynamically. - * "Command substitution": Constructs such as ``cat foo`' and - the equivalent `$(cat foo)' are replaced with the output from - the inner command. + The return value is non-zero if the operation were successful. if + the return value is zero something went wrong which probably means + the programs runs out of memory. - * "Arithmetic expansion": Constructs such as `$(($x-1))' are - replaced with the result of the arithmetic computation. + - Function: void hdestroy_r (struct hsearch_data *HTAB) + The `hdestroy_r' function frees all resources allocated by the + `hcreate_r' function for this very same object HTAB. As for + `hdestroy' it is the programs responsibility to free the strings + for the elements of the table. - 3. "Field splitting": subdivision of the text into "words". + - Function: int hsearch_r (ENTRY ITEM, ACTION ACTION, ENTRY **RETVAL, + struct hsearch_data *HTAB) + The `hsearch_r' function is equivalent to `hsearch'. The meaning + of the first two arguments is identical. But instead of operating + on a single global hashing table the function works on the table + described by the object pointed to by HTAB (which is initialized + by a call to `hcreate_r'). - 4. "Wildcard expansion": The replacement of a construct such as `*.c' - with a list of `.c' file names. Wildcard expansion applies to an - entire word at a time, and replaces that word with 0 or more file - names that are themselves words. + Another difference to `hcreate' is that the pointer to the found + entry in the table is not the return value of the functions. It is + returned by storing it in a pointer variables pointed to by the + RETVAL parameter. The return value of the function is an integer + value indicating success if it is non-zero and failure if it is + zero. In the latter case the global variable ERRNO signals the + reason for the failure. - 5. "Quote removal": The deletion of string-quotes, now that they have - done their job by inhibiting the above transformations when - appropriate. + `ENOMEM' + The table is filled and `hsearch_r' was called with an so far + unknown key and ACTION set to `ENTER'. - For the details of these transformations, and how to write the -constructs that use them, see `The BASH Manual' (to appear). + `ESRCH' + The ACTION parameter is `FIND' and no corresponding element + is found in the table. diff -durpN glibc-2.2.4/manual/libc.info-15 glibc-2.2.5/manual/libc.info-15 --- glibc-2.2.4/manual/libc.info-15 Mon Aug 13 15:03:42 2001 +++ glibc-2.2.5/manual/libc.info-15 Sun Jan 20 19:28:42 2002 @@ -1,4 +1,4 @@ -This is libc.info, produced by makeinfo version 4.0c from libc.texinfo. +This is libc.info, produced by makeinfo version 4.0 from libc.texinfo.

The `tsearch' function family provides a nice interface to +functions to organize possibly large amounts of data by providing a mean +access time proportional to the logarithm of the number of elements. +The GNU C library implementation even guarantees that this bound is +never exceeded even for input data which cause problems for simple +binary tree implementations. - Word expansion produces a vector of words (strings). To return this -vector, `wordexp' uses a special data type, `wordexp_t', which is a -structure. You pass `wordexp' the address of the structure, and it -fills in the structure's fields to tell you about the results. + The functions described in the chapter are all described in the +System V and X/Open specifications and are therefore quite portable. - - Data Type: wordexp_t - This data type holds a pointer to a word vector. More precisely, - it records both the address of the word vector and its size. + In contrast to the `hsearch' functions the `tsearch' functions can +be used with arbitrary data and not only zero-terminated strings. - `we_wordc' - The number of elements in the vector. + The `tsearch' functions have the advantage that no function to +initialize data structures is necessary. A simple pointer of type +`void *' initialized to `NULL' is a valid tree and can be extended or +searched. - `we_wordv' - The address of the vector. This field has type `char **'. + - Function: void * tsearch (const void *KEY, void **ROOTP, + comparison_fn_t COMPAR) + The `tsearch' function searches in the tree pointed to by `*ROOTP' + for an element matching KEY. The function pointed to by COMPAR is + used to determine whether two elements match. *Note Comparison + Functions::, for a specification of the functions which can be + used for the COMPAR parameter. - `we_offs' - The offset of the first real element of the vector, from its - nominal address in the `we_wordv' field. Unlike the other - fields, this is always an input to `wordexp', rather than an - output from it. + If the tree does not contain a matching entry the KEY value will + be added to the tree. `tsearch' does not make a copy of the object + pointed to by KEY (how could it since the size is unknown). + Instead it adds a reference to this object which means the object + must be available as long as the tree data structure is used. - If you use a nonzero offset, then that many elements at the - beginning of the vector are left empty. (The `wordexp' - function fills them with null pointers.) + The tree is represented by a pointer to a pointer since it is + sometimes necessary to change the root node of the tree. So it + must not be assumed that the variable pointed to by ROOTP has the + same value after the call. This also shows that it is not safe to + call the `tsearch' function more than once at the same time using + the same tree. It is no problem to run it more than once at a + time on different trees. - The `we_offs' field is meaningful only if you use the - `WRDE_DOOFFS' flag. Otherwise, the offset is always zero - regardless of what is in this field, and the first real - element comes at the beginning of the vector. + The return value is a pointer to the matching element in the tree. + If a new element was created the pointer points to the new data + (which is in fact KEY). If an entry had to be created and the + program ran out of space `NULL' is returned. - - Function: int wordexp (const char *WORDS, wordexp_t - *WORD-VECTOR-PTR, int FLAGS) - Perform word expansion on the string WORDS, putting the result in - a newly allocated vector, and store the size and address of this - vector into `*WORD-VECTOR-PTR'. The argument FLAGS is a - combination of bit flags; see *Note Flags for Wordexp::, for - details of the flags. + - Function: void * tfind (const void *KEY, void *const *ROOTP, + comparison_fn_t COMPAR) + The `tfind' function is similar to the `tsearch' function. It + locates an element matching the one pointed to by KEY and returns + a pointer to this element. But if no matching element is + available no new element is entered (note that the ROOTP parameter + points to a constant pointer). Instead the function returns + `NULL'. - You shouldn't use any of the characters `|&;<>' in the string - WORDS unless they are quoted; likewise for newline. If you use - these characters unquoted, you will get the `WRDE_BADCHAR' error - code. Don't use parentheses or braces unless they are quoted or - part of a word expansion construct. If you use quotation - characters `'"`', they should come in pairs that balance. + Another advantage of the `tsearch' function in contrast to the +`hsearch' functions is that there is an easy way to remove elements. - The results of word expansion are a sequence of words. The - function `wordexp' allocates a string for each resulting word, then - allocates a vector of type `char **' to store the addresses of - these strings. The last element of the vector is a null pointer. - This vector is called the "word vector". + - Function: void * tdelete (const void *KEY, void **ROOTP, + comparison_fn_t COMPAR) + To remove a specific element matching KEY from the tree `tdelete' + can be used. It locates the matching element using the same + method as `tfind'. The corresponding element is then removed and + a pointer to the parent of the deleted node is returned by the + function. If there is no matching entry in the tree nothing can be + deleted and the function returns `NULL'. If the root of the tree + is deleted `tdelete' returns some unspecified value not equal to + `NULL'. - To return this vector, `wordexp' stores both its address and its - length (number of elements, not counting the terminating null - pointer) into `*WORD-VECTOR-PTR'. + - Function: void tdestroy (void *VROOT, __free_fn_t FREEFCT) + If the complete search tree has to be removed one can use + `tdestroy'. It frees all resources allocated by the `tsearch' + function to generate the tree pointed to by VROOT. - If `wordexp' succeeds, it returns 0. Otherwise, it returns one of - these error codes: + For the data in each tree node the function FREEFCT is called. + The pointer to the data is passed as the argument to the function. + If no such work is necessary FREEFCT must point to a function + doing nothing. It is called in any case. - `WRDE_BADCHAR' - The input string WORDS contains an unquoted invalid character - such as `|'. + This function is a GNU extension and not covered by the System V or + X/Open specifications. - `WRDE_BADVAL' - The input string refers to an undefined shell variable, and - you used the flag `WRDE_UNDEF' to forbid such references. + In addition to the function to create and destroy the tree data +structure, there is another function which allows you to apply a +function to all elements of the tree. The function must have this type: - `WRDE_CMDSUB' - The input string uses command substitution, and you used the - flag `WRDE_NOCMD' to forbid command substitution. + void __action_fn_t (const void *nodep, VISIT value, int level); - `WRDE_NOSPACE' - It was impossible to allocate memory to hold the result. In - this case, `wordexp' can store part of the results--as much - as it could allocate room for. + The NODEP is the data value of the current node (once given as the +KEY argument to `tsearch'). LEVEL is a numeric value which corresponds +to the depth of the current node in the tree. The root node has the +depth 0 and its children have a depth of 1 and so on. The `VISIT' type +is an enumeration type. - `WRDE_SYNTAX' - There was a syntax error in the input string. For example, - an unmatched quoting character is a syntax error. + - Data Type: VISIT + The `VISIT' value indicates the status of the current node in the + tree and how the function is called. The status of a node is + either `leaf' or `internal node'. For each leaf node the function + is called exactly once, for each internal node it is called three + times: before the first child is processed, after the first child + is processed and after both children are processed. This makes it + possible to handle all three methods of tree traversal (or even a + combination of them). - - Function: void wordfree (wordexp_t *WORD-VECTOR-PTR) - Free the storage used for the word-strings and vector that - `*WORD-VECTOR-PTR' points to. This does not free the structure - `*WORD-VECTOR-PTR' itself--only the other data it points to. + `preorder' + The current node is an internal node and the function is + called before the first child was processed. + + `postorder' + The current node is an internal node and the function is + called after the first child was processed. + + `endorder' + The current node is an internal node and the function is + called after the second child was processed. + + `leaf' + The current node is a leaf. + + - Function: void twalk (const void *ROOT, __action_fn_t ACTION) + For each node in the tree with a node pointed to by ROOT, the + `twalk' function calls the function provided by the parameter + ACTION. For leaf nodes the function is called exactly once with + VALUE set to `leaf'. For internal nodes the function is called + three times, setting the VALUE parameter or ACTION to the + appropriate value. The LEVEL argument for the ACTION function is + computed while descending the tree with increasing the value by + one for the descend to a child, starting with the value 0 for the + root node. + + Since the functions used for the ACTION parameter to `twalk' must + not modify the tree data, it is safe to run `twalk' in more than + one thread at the same time, working on the same tree.

You can -use `~USER' to stand for USER's home directory. + The archetypal use of wildcards is for matching against the files in +a directory, and making a list of all the matches. This is called +"globbing". - "Tilde expansion" is the process of converting these abbreviations -to the directory names that they stand for. + You could do this using `fnmatch', by reading the directory entries +one by one and testing each one with `fnmatch'. But that would be slow +(and complex, since you would have to handle subdirectories by hand). - Tilde expansion applies to the `~' plus all following characters up -to whitespace or a slash. It takes place only at the beginning of a -word, and only if none of the characters to be transformed is quoted in -any way. + The library provides a function `glob' to make this particular use +of wildcards convenient. `glob' and the other symbols in this section +are declared in `glob.h'. - Plain `~' uses the value of the environment variable `HOME' as the -proper home directory name. `~' followed by a user name uses -`getpwname' to look up that user in the user database, and uses -whatever directory is recorded there. Thus, `~' followed by your own -name can give different results from plain `~', if the value of `HOME' -is not really your home directory. +* Menu: + +* Calling Glob:: Basic use of `glob'. +* Flags for Globbing:: Flags that enable various options in `glob'. +* More Flags for Globbing:: GNU specific extensions to `glob'.  -File: libc.info, Node: Variable Substitution, Prev: Tilde Expansion, Up: Word Expansion +File: libc.info, Node: Calling Glob, Next: Flags for Globbing, Up: Globbing -Details of Variable Substitution --------------------------------- +Calling `glob' +-------------- - Part of ordinary shell syntax is the use of `$VARIABLE' to -substitute the value of a shell variable into a command. This is called -"variable substitution", and it is one part of doing word expansion. + The result of globbing is a vector of file names (strings). To +return this vector, `glob' uses a special data type, `glob_t', which is +a structure. You pass `glob' the address of the structure, and it +fills in the structure's fields to tell you about the results. - There are two basic ways you can write a variable reference for -substitution: + - Data Type: glob_t + This data type holds a pointer to a word vector. More precisely, + it records both the address of the word vector and its size. The + GNU implementation contains some more fields which are non-standard + extensions. -`${VARIABLE}' - If you write braces around the variable name, then it is completely - unambiguous where the variable name ends. You can concatenate - additional letters onto the end of the variable value by writing - them immediately after the close brace. For example, `${foo}s' - expands into `tractors'. + `gl_pathc' + The number of elements in the vector, excluding the initial + null entries if the GLOB_DOOFFS flag is used (see gl_offs + below). -`$VARIABLE' - If you do not put braces around the variable name, then the - variable name consists of all the alphanumeric characters and - underscores that follow the `$'. The next punctuation character - ends the variable name. Thus, `$foo-bar' refers to the variable - `foo' and expands into `tractor-bar'. + `gl_pathv' + The address of the vector. This field has type `char **'. - When you use braces, you can also use various constructs to modify -the value that is substituted, or test it in various ways. + `gl_offs' + The offset of the first real element of the vector, from its + nominal address in the `gl_pathv' field. Unlike the other + fields, this is always an input to `glob', rather than an + output from it. -`${VARIABLE:-DEFAULT}' - Substitute the value of VARIABLE, but if that is empty or - undefined, use DEFAULT instead. + If you use a nonzero offset, then that many elements at the + beginning of the vector are left empty. (The `glob' function + fills them with null pointers.) -`${VARIABLE:=DEFAULT}' - Substitute the value of VARIABLE, but if that is empty or - undefined, use DEFAULT instead and set the variable to DEFAULT. + The `gl_offs' field is meaningful only if you use the + `GLOB_DOOFFS' flag. Otherwise, the offset is always zero + regardless of what is in this field, and the first real + element comes at the beginning of the vector. -`${VARIABLE:?MESSAGE}' - If VARIABLE is defined and not empty, substitute its value. + `gl_closedir' + The address of an alternative implementation of the `closedir' + function. It is used if the `GLOB_ALTDIRFUNC' bit is set in + the flag parameter. The type of this field is + `void (*) (void *)'. - Otherwise, print MESSAGE as an error message on the standard error - stream, and consider word expansion a failure. + This is a GNU extension. -`${VARIABLE:+REPLACEMENT}' - Substitute REPLACEMENT, but only if VARIABLE is defined and - nonempty. Otherwise, substitute nothing for this construct. + `gl_readdir' + The address of an alternative implementation of the `readdir' + function used to read the contents of a directory. It is + used if the `GLOB_ALTDIRFUNC' bit is set in the flag + parameter. The type of this field is + `struct dirent *(*) (void *)'. -`${#VARIABLE}' - Substitute a numeral which expresses in base ten the number of - characters in the value of VARIABLE. `${#foo}' stands for `7', - because `tractor' is seven characters. + This is a GNU extension. - These variants of variable substitution let you remove part of the -variable's value before substituting it. The PREFIX and SUFFIX are not -mere strings; they are wildcard patterns, just like the patterns that -you use to match multiple file names.

You can turn this off with the flag `GLOB_NOSORT' + if you want to get the information as fast as possible. Usually + it's a good idea to let `glob' sort them--if you process the files + in alphabetical order, the users will have a feel for the rate of + progress that your application is making. - Before you can read or write the contents of a file, you must -establish a connection or communications channel to the file. This -process is called "opening" the file. You can open a file for reading, -writing, or both. + If `glob' succeeds, it returns 0. Otherwise, it returns one of + these error codes: - The connection to an open file is represented either as a stream or -as a file descriptor. You pass this as an argument to the functions -that do the actual read or write operations, to tell them which file to -operate on. Certain functions expect streams, and others are designed -to operate on file descriptors. + `GLOB_ABORTED' + There was an error opening a directory, and you used the flag + `GLOB_ERR' or your specified ERRFUNC returned a nonzero value. + *Note Flags for Globbing::, for an explanation of the + `GLOB_ERR' flag and ERRFUNC. - When you have finished reading to or writing from the file, you can -terminate the connection by "closing" the file. Once you have closed a -stream or file descriptor, you cannot do any more input or output -operations on it. + `GLOB_NOMATCH' + The pattern didn't match any existing files. If you use the + `GLOB_NOCHECK' flag, then you never get this error code, + because that flag tells `glob' to _pretend_ that the pattern + matched at least one file. -* Menu: + `GLOB_NOSPACE' + It was impossible to allocate memory to hold the result. -* Streams and File Descriptors:: The GNU Library provides two ways - to access the contents of files. -* File Position:: The number of bytes from the - beginning of the file. + In the event of an error, `glob' stores information in + `*VECTOR-PTR' about all the matches it has found so far. + + It is important to notice that the `glob' function will not fail if + it encounters directories or files which cannot be handled without + the LFS interfaces. The implementation of `glob' is supposed to + use these functions internally. This at least is the assumptions + made by the Unix standard. The GNU extension of allowing the user + to provide own directory handling and `stat' functions complicates + things a bit. If these callback functions are used and a large + file or directory is encountered `glob' _can_ fail. + + - Function: int glob64 (const char *PATTERN, int FLAGS, int (*ERRFUNC) + (const char *FILENAME, int ERROR-CODE), glob64_t *VECTOR-PTR) + The `glob64' function was added as part of the Large File Summit + extensions but is not part of the original LFS proposal. The + reason for this is simple: it is not necessary. The necessity for + a `glob64' function is added by the extensions of the GNU `glob' + implementation which allows the user to provide own directory + handling and `stat' functions. The `readdir' and `stat' functions + do depend on the choice of `_FILE_OFFSET_BITS' since the definition + of the types `struct dirent' and `struct stat' will change + depending on the choice. + + Beside this difference the `glob64' works just like `glob' in all + aspects. + + This function is a GNU extension.  -File: libc.info, Node: Streams and File Descriptors, Next: File Position, Up: I/O Concepts +File: libc.info, Node: Flags for Globbing, Next: More Flags for Globbing, Prev: Calling Glob, Up: Globbing -Streams and File Descriptors ----------------------------- +Flags for Globbing +------------------ - When you want to do input or output to a file, you have a choice of -two basic mechanisms for representing the connection between your -program and the file: file descriptors and streams. File descriptors -are represented as objects of type `int', while streams are represented -as `FILE *' objects. + This section describes the flags that you can specify in the FLAGS +argument to `glob'. Choose the flags you want, and combine them with +the C bitwise OR operator `|'. - File descriptors provide a primitive, low-level interface to input -and output operations. Both file descriptors and streams can represent -a connection to a device (such as a terminal), or a pipe or socket for -communicating with another process, as well as a normal file. But, if -you want to do control operations that are specific to a particular kind -of device, you must use a file descriptor; there are no facilities to -use streams in this way. You must also use file descriptors if your -program needs to do input or output in special modes, such as -nonblocking (or polled) input (*note File Status Flags::). +`GLOB_APPEND' + Append the words from this expansion to the vector of words + produced by previous calls to `glob'. This way you can + effectively expand several words as if they were concatenated with + spaces between them. - Streams provide a higher-level interface, layered on top of the -primitive file descriptor facilities. The stream interface treats all -kinds of files pretty much alike--the sole exception being the three -styles of buffering that you can choose (*note Stream Buffering::). + In order for appending to work, you must not modify the contents + of the word vector structure between calls to `glob'. And, if you + set `GLOB_DOOFFS' in the first call to `glob', you must also set + it when you append to the results. - The main advantage of using the stream interface is that the set of -functions for performing actual input and output operations (as opposed -to control operations) on streams is much richer and more powerful than -the corresponding facilities for file descriptors. The file descriptor -interface provides only simple functions for transferring blocks of -characters, but the stream interface also provides powerful formatted -input and output functions (`printf' and `scanf') as well as functions -for character- and line-oriented input and output. + Note that the pointer stored in `gl_pathv' may no longer be valid + after you call `glob' the second time, because `glob' might have + relocated the vector. So always fetch `gl_pathv' from the + `glob_t' structure after each `glob' call; *never* save the + pointer across calls. - Since streams are implemented in terms of file descriptors, you can -extract the file descriptor from a stream and perform low-level -operations directly on the file descriptor. You can also initially open -a connection as a file descriptor and then make a stream associated with -that file descriptor. +`GLOB_DOOFFS' + Leave blank slots at the beginning of the vector of words. The + `gl_offs' field says how many slots to leave. The blank slots + contain null pointers. - In general, you should stick with using streams rather than file -descriptors, unless there is some specific operation you want to do that -can only be done on a file descriptor. If you are a beginning -programmer and aren't sure what functions to use, we suggest that you -concentrate on the formatted input functions (*note Formatted Input::) -and formatted output functions (*note Formatted Output::). +`GLOB_ERR' + Give up right away and report an error if there is any difficulty + reading the directories that must be read in order to expand + PATTERN fully. Such difficulties might include a directory in + which you don't have the requisite access. Normally, `glob' tries + its best to keep on going despite any errors, reading whatever + directories it can. - If you are concerned about portability of your programs to systems -other than GNU, you should also be aware that file descriptors are not -as portable as streams. You can expect any system running ISO C to -support streams, but non-GNU systems may not support file descriptors at -all, or may only implement a subset of the GNU functions that operate on -file descriptors. Most of the file descriptor functions in the GNU -library are included in the POSIX.1 standard, however. + You can exercise even more control than this by specifying an + error-handler function ERRFUNC when you call `glob'. If ERRFUNC + is not a null pointer, then `glob' doesn't give up right away when + it can't read a directory; instead, it calls ERRFUNC with two + arguments, like this: - -File: libc.info, Node: File Position, Prev: Streams and File Descriptors, Up: I/O Concepts + (*ERRFUNC) (FILENAME, ERROR-CODE) -File Position -------------- + The argument FILENAME is the name of the directory that `glob' + couldn't open or couldn't read, and ERROR-CODE is the `errno' + value that was reported to `glob'. - One of the attributes of an open file is its "file position" that -keeps track of where in the file the next character is to be read or -written. In the GNU system, and all POSIX.1 systems, the file position -is simply an integer representing the number of bytes from the beginning -of the file. + If the error handler function returns nonzero, then `glob' gives up + right away. Otherwise, it continues. - The file position is normally set to the beginning of the file when -it is opened, and each time a character is read or written, the file -position is incremented. In other words, access to the file is normally -"sequential". +`GLOB_MARK' + If the pattern matches the name of a directory, append `/' to the + directory's name when returning it. - Ordinary files permit read or write operations at any position within -the file. Some other kinds of files may also permit this. Files which -do permit this are sometimes referred to as "random-access" files. You -can change the file position using the `fseek' function on a stream -(*note File Positioning::) or the `lseek' function on a file descriptor -(*note I/O Primitives::). If you try to change the file position on a -file that doesn't support random access, you get the `ESPIPE' error. +`GLOB_NOCHECK' + If the pattern doesn't match any file names, return the pattern + itself as if it were a file name that had been matched. + (Normally, when the pattern doesn't match anything, `glob' returns + that there were no matches.) - Streams and descriptors that are opened for "append access" are -treated specially for output: output to such files is _always_ appended -sequentially to the _end_ of the file, regardless of the file position. -However, the file position is still used to control where in the file -reading is done. +`GLOB_NOSORT' + Don't sort the file names; return them in no particular order. + (In practice, the order will depend on the order of the entries in + the directory.) The only reason _not_ to sort is to save time. - If you think about it, you'll realize that several programs can read -a given file at the same time. In order for each program to be able to -read the file at its own pace, each program must have its own file -pointer, which is not affected by anything the other programs do. +`GLOB_NOESCAPE' + Don't treat the `\' character specially in patterns. Normally, + `\' quotes the following character, turning off its special meaning + (if any) so that it matches only itself. When quoting is enabled, + the pattern `\?' matches only the string `?', because the question + mark in the pattern acts like an ordinary character. - In fact, each opening of a file creates a separate file position. -Thus, if you open a file twice even in the same program, you get two -streams or descriptors with independent file positions. + If you use `GLOB_NOESCAPE', then `\' is an ordinary character. - By contrast, if you open a descriptor and then duplicate it to get -another descriptor, these two descriptors share the same file position: -changing the file position of one descriptor will affect the other. + `glob' does its work by calling the function `fnmatch' repeatedly. + It handles the flag `GLOB_NOESCAPE' by turning on the + `FNM_NOESCAPE' flag in calls to `fnmatch'.  -File: libc.info, Node: File Names, Prev: I/O Concepts, Up: I/O Overview +File: libc.info, Node: More Flags for Globbing, Prev: Flags for Globbing, Up: Globbing -File Names -========== +More Flags for Globbing +----------------------- - In order to open a connection to a file, or to perform other -operations such as deleting a file, you need some way to refer to the -file.

It returns that information +by storing the offsets into an array whose elements are structures of +type `regmatch_t'. The first element of the array (index `0') records +the part of the string that matched the entire regular expression. +Each other element of the array records the beginning and end of the +part that matched a single parenthetical subexpression. - The OPENTYPE argument is a string that controls how the file is - opened and specifies attributes of the resulting stream. It must - begin with one of the following sequences of characters: + - Data Type: regmatch_t + This is the data type of the MATCHARRAY array that you pass to + `regexec'. It contains two structure fields, as follows: - `r' - Open an existing file for reading only. + `rm_so' + The offset in STRING of the beginning of a substring. Add + this value to STRING to get the address of that part. - `w' - Open the file for writing only. If the file already exists, - it is truncated to zero length. Otherwise a new file is - created. + `rm_eo' + The offset in STRING of the end of the substring. - `a' - Open a file for append access; that is, writing at the end of - file only. If the file already exists, its initial contents - are unchanged and output to the stream is appended to the end - of the file. Otherwise, a new, empty file is created. + - Data Type: regoff_t + `regoff_t' is an alias for another signed integer type. The + fields of `regmatch_t' have type `regoff_t'. - `r+' - Open an existing file for both reading and writing. The - initial contents of the file are unchanged and the initial - file position is at the beginning of the file. + The `regmatch_t' elements correspond to subexpressions positionally; +the first element (index `1') records where the first subexpression +matched, the second element records the second subexpression, and so +on. The order of the subexpressions is the order in which they begin. - `w+' - Open a file for both reading and writing. If the file - already exists, it is truncated to zero length. Otherwise, a - new file is created. + When you call `regexec', you specify how long the MATCHPTR array is, +with the NMATCH argument. This tells `regexec' how many elements to +store. If the actual regular expression has more than NMATCH +subexpressions, then you won't get offset information about the rest of +them. But this doesn't alter whether the pattern matches a particular +string or not. - `a+' - Open or create file for both reading and appending. If the - file exists, its initial contents are unchanged. Otherwise, - a new file is created. The initial file position for reading - is at the beginning of the file, but output is always - appended to the end of the file. + If you don't want `regexec' to return any information about where +the subexpressions matched, you can either supply `0' for NMATCH, or +use the flag `REG_NOSUB' when you compile the pattern with `regcomp'. - As you can see, `+' requests a stream that can do both input and - output. The ISO standard says that when using such a stream, you - must call `fflush' (*note Stream Buffering::) or a file positioning - function such as `fseek' (*note File Positioning::) when switching - from reading to writing or vice versa. Otherwise, internal buffers - might not be emptied properly. The GNU C library does not have - this limitation; you can do arbitrary reading and writing - operations on a stream in whatever order. + +File: libc.info, Node: Subexpression Complications, Next: Regexp Cleanup, Prev: Regexp Subexpressions, Up: Regular Expressions - Additional characters may appear after these to specify flags for - the call. Always put the mode (`r', `w+', etc.) first; that is - the only part you are guaranteed will be understood by all systems. +Complications in Subexpression Matching +--------------------------------------- - The GNU C library defines one additional character for use in - OPENTYPE: the character `x' insists on creating a new file--if a - file FILENAME already exists, `fopen' fails rather than opening - it. If you use `x' you are guaranteed that you will not clobber - an existing file. This is equivalent to the `O_EXCL' option to - the `open' function (*note Opening and Closing Files::). + Sometimes a subexpression matches a substring of no characters. This +happens when `f\(o*\)' matches the string `fum'. (It really matches +just the `f'.) In this case, both of the offsets identify the point in +the string where the null substring was found. In this example, the +offsets are both `1'. - The character `b' in OPENTYPE has a standard meaning; it requests - a binary stream rather than a text stream. But this makes no - difference in POSIX systems (including the GNU system). If both - `+' and `b' are specified, they can appear in either order. *Note - Binary Streams::. + Sometimes the entire regular expression can match without using some +of its subexpressions at all--for example, when `ba\(na\)*' matches the +string `ba', the parenthetical subexpression is not used. When this +happens, `regexec' stores `-1' in both fields of the element for that +subexpression. - If the OPENTYPE string contains the sequence `,ccs=STRING' then - STRING is taken as the name of a coded character set and `fopen' - will mark the stream as wide-oriented which appropriate conversion - functions in place to convert from and to the character set STRING - is place. Any other stream is opened initially unoriented and the - orientation is decided with the first file operation. If the - first operation is a wide character operation, the stream is not - only marked as wide-oriented, also the conversion functions to - convert to the coded character set used for the current locale are - loaded. This will not change anymore from this point on even if - the locale selected for the `LC_CTYPE' category is changed. + Sometimes matching the entire regular expression can match a +particular subexpression more than once--for example, when `ba\(na\)*' +matches the string `bananana', the parenthetical subexpression matches +three times. When this happens, `regexec' usually stores the offsets +of the last part of the string that matched the subexpression. In the +case of `bananana', these offsets are `6' and `8'. - Any other characters in OPENTYPE are simply ignored. They may be - meaningful in other systems. + But the last match is not always the one that is chosen. It's more +accurate to say that the last _opportunity_ to match is the one that +takes precedence. What this means is that when one subexpression +appears within another, then the results reported for the inner +subexpression reflect whatever happened on the last match of the outer +subexpression. For an example, consider `\(ba\(na\)*s \)*' matching +the string `bananas bas '. The last time the inner expression actually +matches is near the end of the first word. But it is _considered_ +again in the second word, and fails to match there. `regexec' reports +nonuse of the "na" subexpression. - If the open fails, `fopen' returns a null pointer. + Another place where this rule applies is when the regular expression + \(ba\(na\)*s \|nefer\(ti\)* \)* - When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a - 32 bit machine this function is in fact `fopen64' since the LFS - interface replaces transparently the old interface. +matches `bananas nefertiti'. The "na" subexpression does match in the +first word, but it doesn't match in the second word because the other +alternative is used there. Once again, the second repetition of the +outer subexpression overrides the first, and within that second +repetition, the "na" subexpression is not used. So `regexec' reports +nonuse of the "na" subexpression. - You can have multiple streams (or file descriptors) pointing to the -same file open at the same time. If you do only input, this works -straightforwardly, but you must be careful if any output streams are -included. *Note Stream/Descriptor Precautions::. This is equally true -whether the streams are in one program (not usual) or in several -programs (which can easily happen).

There is no - special `FILE' type for the LFS interface. + When you are finished using a compiled regular expression, you can +free the storage it uses by calling `regfree'. - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `fopen' and - so transparently replaces the old interface. + - Function: void regfree (regex_t *COMPILED) + Calling `regfree' frees all the storage that `*COMPILED' points + to.

It - first closes the stream referred to by STREAM, ignoring any errors - that are detected in the process. (Because errors are ignored, - you should not use `freopen' on an output stream if you have - actually done any output using the stream.) Then the file named by - FILENAME is opened with mode OPENTYPE as for `fopen', and - associated with the same stream object STREAM. + You should always free the space in a `regex_t' structure with +`regfree' before using the structure to compile another regular +expression. - If the operation fails, a null pointer is returned; otherwise, - `freopen' returns STREAM. + When `regcomp' or `regexec' reports an error, you can use the +function `regerror' to turn it into an error message string. - `freopen' has traditionally been used to connect a standard stream - such as `stdin' with a file of your own choice. This is useful in - programs in which use of a standard stream for certain purposes is - hard-coded. In the GNU C library, you can simply close the - standard streams and open new ones with `fopen'. But other - systems lack this ability, so using `freopen' is more portable. + - Function: size_t regerror (int ERRCODE, regex_t *COMPILED, char + *BUFFER, size_t LENGTH) + This function produces an error message string for the error code + ERRCODE, and stores the string in LENGTH bytes of memory starting + at BUFFER. For the COMPILED argument, supply the same compiled + regular expression structure that `regcomp' or `regexec' was + working with when it got the error. Alternatively, you can supply + `NULL' for COMPILED; you will still get a meaningful error + message, but it might not be as detailed. - When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a - 32 bit machine this function is in fact `freopen64' since the LFS - interface replaces transparently the old interface. + If the error message can't fit in LENGTH bytes (including a + terminating null character), then `regerror' truncates it. The + string that `regerror' stores is always null-terminated even if it + has been truncated. - - Function: FILE * freopen64 (const char *FILENAME, const char - *OPENTYPE, FILE *STREAM) - This function is similar to `freopen'. The only difference is that - on 32 bit machine the stream returned is able to read beyond the - 2^31 bytes limits imposed by the normal interface. It should be - noted that the stream pointed to by STREAM need not be opened - using `fopen64' or `freopen64' since its mode is not important for - this function. + The return value of `regerror' is the minimum length needed to + store the entire error message. If this is less than LENGTH, then + the error message was not truncated, and you can use it. + Otherwise, you should call `regerror' again with a larger buffer. - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `freopen' - and so transparently replaces the old interface. + Here is a function which uses `regerror', but always dynamically + allocates a buffer for the error message: - In some situations it is useful to know whether a given stream is -available for reading or writing.

The - `fcloseall' function returns a value of `0' if all the files were - closed successfully, and `EOF' if an error was detected. + * "Arithmetic expansion": Constructs such as `$(($x-1))' are + replaced with the result of the arithmetic computation. - This function should be used only in special situations, e.g., - when an error occurred and the program must be aborted. Normally - each single stream should be closed separately so that problems - with individual streams can be identified. It is also problematic - since the standard streams (*note Standard Streams::) will also be - closed. + 3. "Field splitting": subdivision of the text into "words". - The function `fcloseall' is declared in `stdio.h'. + 4. "Wildcard expansion": The replacement of a construct such as `*.c' + with a list of `.c' file names. Wildcard expansion applies to an + entire word at a time, and replaces that word with 0 or more file + names that are themselves words. - If the `main' function to your program returns, or if you call the -`exit' function (*note Normal Termination::), all open streams are -automatically closed properly. If your program terminates in any other -manner, such as by calling the `abort' function (*note Aborting a -Program::) or from a fatal signal (*note Signal Handling::), open -streams might not be closed properly. Buffered output might not be -flushed and files may be incomplete. For more information on buffering -of streams, see *Note Stream Buffering::. + 5.

But the programmer must -be aware of a the possible complications. It is important to know about -these also if the program one writes never use threads since the design -and implementation of many stream functions is heavily influenced by the -requirements added by multi-threaded programming. + All the functions, constants and data types for word expansion are +declared in the header file `wordexp.h'. - The POSIX standard requires that by default the stream operations are -atomic. I.e., issuing two stream operations for the same stream in two -threads at the same time will cause the operations to be executed as if -they were issued sequentially. The buffer operations performed while -reading or writing are protected from other uses of the same stream. To -do this each stream has an internal lock object which has to be -(implicitly) acquired before any work can be done. + Word expansion produces a vector of words (strings). To return this +vector, `wordexp' uses a special data type, `wordexp_t', which is a +structure. You pass `wordexp' the address of the structure, and it +fills in the structure's fields to tell you about the results. - But there are situations where this is not enough and there are also -situations where this is not wanted. The implicit locking is not enough -if the program requires more than one stream function call to happen -atomically. One example would be if an output line a program wants to -generate is created by several function calls. The functions by -themselves would ensure only atomicity of their own operation, but not -atomicity over all the function calls. For this it is necessary to -perform the stream locking in the application code. + - Data Type: wordexp_t + This data type holds a pointer to a word vector. More precisely, + it records both the address of the word vector and its size. - - Function: void flockfile (FILE *STREAM) - The `flockfile' function acquires the internal locking object - associated with the stream STREAM. This ensures that no other - thread can explicitly through `flockfile'/`ftrylockfile' or - implicit through a call of a stream function lock the stream. The - thread will block until the lock is acquired. An explicit call to - `funlockfile' has to be used to release the lock. + `we_wordc' + The number of elements in the vector. - - Function: int ftrylockfile (FILE *STREAM) - The `ftrylockfile' function tries to acquire the internal locking - object associated with the stream STREAM just like `flockfile'. - But unlike `flockfile' this function does not block if the lock is - not available. `ftrylockfile' returns zero if the lock was - successfully acquired. Otherwise the stream is locked by another - thread. + `we_wordv' + The address of the vector. This field has type `char **'. - - Function: void funlockfile (FILE *STREAM) - The `funlockfile' function releases the internal locking object of - the stream STREAM. The stream must have been locked before by a - call to `flockfile' or a successful call of `ftrylockfile'. The - implicit locking performed by the stream operations do not count. - The `funlockfile' function does not return an error status and the - behavior of a call for a stream which is not locked by the current - thread is undefined. + `we_offs' + The offset of the first real element of the vector, from its + nominal address in the `we_wordv' field. Unlike the other + fields, this is always an input to `wordexp', rather than an + output from it. - The following example shows how the functions above can be used to -generate an output line atomically even in multi-threaded applications -(yes, the same job could be done with one `fprintf' call but it is -sometimes not possible): + If you use a nonzero offset, then that many elements at the + beginning of the vector are left empty. (The `wordexp' + function fills them with null pointers.) - FILE *fp; - { - ... - flockfile (fp); - fputs ("This is test number ", fp); - fprintf (fp, "%d\n", test); - funlockfile (fp) - } + The `we_offs' field is meaningful only if you use the + `WRDE_DOOFFS' flag. Otherwise, the offset is always zero + regardless of what is in this field, and the first real + element comes at the beginning of the vector. - Without the explicit locking it would be possible for another thread -to use the stream FP after the `fputs' call return and before `fprintf' -was called with the result that the number does not follow the word -`number'. + - Function: int wordexp (const char *WORDS, wordexp_t + *WORD-VECTOR-PTR, int FLAGS) + Perform word expansion on the string WORDS, putting the result in + a newly allocated vector, and store the size and address of this + vector into `*WORD-VECTOR-PTR'. The argument FLAGS is a + combination of bit flags; see *Note Flags for Wordexp::, for + details of the flags. - From this description it might already be clear that the locking -objects in streams are no simple mutexes. Since locking the same -stream twice in the same thread is allowed the locking objects must be -equivalent to recursive mutexes. These mutexes keep track of the owner -and the number of times the lock is acquired. The same number of -`funlockfile' calls by the same threads is necessary to unlock the -stream completely. For instance: + You shouldn't use any of the characters `|&;<>' in the string + WORDS unless they are quoted; likewise for newline. If you use + these characters unquoted, you will get the `WRDE_BADCHAR' error + code. Don't use parentheses or braces unless they are quoted or + part of a word expansion construct. If you use quotation + characters `'"`', they should come in pairs that balance. - void - foo (FILE *fp) - { - ftrylockfile (fp); - fputs ("in foo\n", fp); - /* This is very wrong!!! */ - funlockfile (fp); - } + The results of word expansion are a sequence of words. The + function `wordexp' allocates a string for each resulting word, then + allocates a vector of type `char **' to store the addresses of + these strings. The last element of the vector is a null pointer. + This vector is called the "word vector". - It is important here that the `funlockfile' function is only called -if the `ftrylockfile' function succeeded in locking the stream. It is -therefore always wrong to ignore the result of `ftrylockfile'. And it -makes no sense since otherwise one would use `flockfile'. The result -of code like that above is that either `funlockfile' tries to free a -stream that hasn't been locked by the current thread or it frees the -stream prematurely. The code should look like this: + To return this vector, `wordexp' stores both its address and its + length (number of elements, not counting the terminating null + pointer) into `*WORD-VECTOR-PTR'. - void - foo (FILE *fp) - { - if (ftrylockfile (fp) == 0) - { - fputs ("in foo\n", fp); - funlockfile (fp); - } - } + If `wordexp' succeeds, it returns 0. Otherwise, it returns one of + these error codes: - Now that we covered why it is necessary to have these locking it is -necessary to talk about situations when locking is unwanted and what can -be done. The locking operations (explicit or implicit) don't come for -free. Even if a lock is not taken the cost is not zero. The operations -which have to be performed require memory operations that are safe in -multi-processor environments. With the many local caches involved in -such systems this is quite costly. So it is best to avoid the locking -completely if it is not needed - because the code in question is never -used in a context where two or more threads may use a stream at a time. -This can be determined most of the time for application code; for -library code which can be used in many contexts one should default to be -conservative and use locking. + `WRDE_BADCHAR' + The input string WORDS contains an unquoted invalid character + such as `|'. - There are two basic mechanisms to avoid locking. The first is to use -the `_unlocked' variants of the stream operations. The POSIX standard -defines quite a few of those and the GNU library adds a few more. -These variants of the functions behave just like the functions with the -name without the suffix except that they do not lock the stream. Using -these functions is very desirable since they are potentially much -faster. This is not only because the locking operation itself is -avoided. More importantly, functions like `putc' and `getc' are very -simple and traditionally (before the introduction of threads) were -implemented as macros which are very fast if the buffer is not empty. -With the addition of locking requirements these functions are no longer -implemented as macros since they would would expand to too much code. -But these macros are still available with the same functionality under -the new names `putc_unlocked' and `getc_unlocked'. This possibly huge -difference of speed also suggests the use of the `_unlocked' functions -even if locking is required. The difference is that the locking then -has to be performed in the program: + `WRDE_BADVAL' + The input string refers to an undefined shell variable, and + you used the flag `WRDE_UNDEF' to forbid such references. - void - foo (FILE *fp, char *buf) - { - flockfile (fp); - while (*buf != '/') - putc_unlocked (*buf++, fp); - funlockfile (fp); - } + `WRDE_CMDSUB' + The input string uses command substitution, and you used the + flag `WRDE_NOCMD' to forbid command substitution. - If in this example the `putc' function would be used and the -explicit locking would be missing the `putc' function would have to -acquire the lock in every call, potentially many times depending on when -the loop terminates. Writing it the way illustrated above allows the -`putc_unlocked' macro to be used which means no locking and direct -manipulation of the buffer of the stream. + `WRDE_NOSPACE' + It was impossible to allocate memory to hold the result. In + this case, `wordexp' can store part of the results--as much + as it could allocate room for. - A second way to avoid locking is by using a non-standard function -which was introduced in Solaris and is available in the GNU C library -as well. + `WRDE_SYNTAX' + There was a syntax error in the input string. For example, + an unmatched quoting character is a syntax error. - - Function: int __fsetlocking (FILE *STREAM, int TYPE) - The `__fsetlocking' function can be used to select whether the - stream operations will implicitly acquire the locking object of the - stream STREAM. By default this is done but it can be disabled and - reinstated using this function. There are three values defined - for the TYPE parameter. + - Function: void wordfree (wordexp_t *WORD-VECTOR-PTR) + Free the storage used for the word-strings and vector that + `*WORD-VECTOR-PTR' points to. This does not free the structure + `*WORD-VECTOR-PTR' itself--only the other data it points to. - `FSETLOCKING_INTERNAL' - The stream `stream' will from now on use the default internal - locking. Every stream operation with exception of the - `_unlocked' variants will implicitly lock the stream. + +File: libc.info, Node: Flags for Wordexp, Next: Wordexp Example, Prev: Calling Wordexp, Up: Word Expansion - `FSETLOCKING_BYCALLER' - After the `__fsetlocking' function returns the user is - responsible for locking the stream. None of the stream - operations will implicitly do this anymore until the state is - set back to `FSETLOCKING_INTERNAL'. +Flags for Word Expansion +------------------------ - `FSETLOCKING_QUERY' - `__fsetlocking' only queries the current locking state of the - stream.

Choose the flags you want, and combine them +with the C operator `|'. - The return value of `__fsetlocking' is either - `FSETLOCKING_INTERNAL' or `FSETLOCKING_BYCALLER' depending on the - state of the stream before the call. +`WRDE_APPEND' + Append the words from this expansion to the vector of words + produced by previous calls to `wordexp'. This way you can + effectively expand several words as if they were concatenated with + spaces between them. - This function and the values for the TYPE parameter are declared - in `stdio_ext.h'. + In order for appending to work, you must not modify the contents + of the word vector structure between calls to `wordexp'. And, if + you set `WRDE_DOOFFS' in the first call to `wordexp', you must also + set it when you append to the results. - This function is especially useful when program code has to be used -which is written without knowledge about the `_unlocked' functions (or -if the programmer was too lazy to use them). +`WRDE_DOOFFS' + Leave blank slots at the beginning of the vector of words. The + `we_offs' field says how many slots to leave. The blank slots + contain null pointers. - -File: libc.info, Node: Streams and I18N, Next: Simple Output, Prev: Streams and Threads, Up: I/O on Streams +`WRDE_NOCMD' + Don't do command substitution; if the input requests command + substitution, report an error. -Streams in Internationalized Applications -========================================= +`WRDE_REUSE' + Reuse a word vector made by a previous call to `wordexp'. Instead + of allocating a new vector of words, this call to `wordexp' will + use the vector that already exists (making it larger if necessary). - ISO C90 introduced the new type `wchar_t' to allow handling larger -character sets. What was missing was a possibility to output strings -of `wchar_t' directly. One had to convert them into multibyte strings -using `mbstowcs' (there was no `mbsrtowcs' yet) and then use the normal -stream functions. While this is doable it is very cumbersome since -performing the conversions is not trivial and greatly increases program -complexity and size. + Note that the vector may move, so it is not safe to save an old + pointer and use it again after calling `wordexp'. You must fetch + `we_pathv' anew after each call. - The Unix standard early on (I think in XPG4.2) introduced two -additional format specifiers for the `printf' and `scanf' families of -functions. Printing and reading of single wide characters was made -possible using the `%C' specifier and wide character strings can be -handled with `%S'. These modifiers behave just like `%c' and `%s' only -that they expect the corresponding argument to have the wide character -type and that the wide character and string are transformed into/from -multibyte strings before being used. +`WRDE_SHOWERR' + Do show any error messages printed by commands run by command + substitution. More precisely, allow these commands to inherit the + standard error output stream of the current process. By default, + `wordexp' gives these commands a standard error stream that + discards all output. - This was a beginning but it is still not good enough. Not always is -it desirable to use `printf' and `scanf'. The other, smaller and -faster functions cannot handle wide characters. Second, it is not -possible to have a format string for `printf' and `scanf' consisting of -wide characters. The result is that format strings would have to be -generated if they have to contain non-basic characters. +`WRDE_UNDEF' + If the input refers to a shell variable that is not defined, + report an error. - In the Amendment 1 to ISO C90 a whole new set of functions was added -to solve the problem. Most of the stream functions got a counterpart -which take a wide character or wide character string instead of a -character or string respectively. The new functions operate on the -same streams (like `stdout'). This is different from the model of the -C++ runtime library where separate streams for wide and normal I/O are -used. + +File: libc.info, Node: Wordexp Example, Next: Tilde Expansion, Prev: Flags for Wordexp, Up: Word Expansion - Being able to use the same stream for wide and normal operations -comes with a restriction: a stream can be used either for wide -operations or for normal operations.

The orientation can be decided in three ways: +`wordexp' Example +----------------- - * If any of the normal character functions is used (this includes the - `fread' and `fwrite' functions) the stream is marked as not wide - oriented. + Here is an example of using `wordexp' to expand several strings and +use the results to run a shell command.

There are no diagnostics issued. The application behavior -will simply be strange or the application will simply crash. The -`fwide' function can help avoiding this. +Details of Tilde Expansion +-------------------------- - - Function: int fwide (FILE *STREAM, int MODE) - The `fwide' function can be used to set and query the state of the - orientation of the stream STREAM. If the MODE parameter has a - positive value the streams get wide oriented, for negative values - narrow oriented. It is not possible to overwrite previous - orientations with `fwide'. I.e., if the stream STREAM was already - oriented before the call nothing is done. + It's a standard part of shell syntax that you can use `~' at the +beginning of a file name to stand for your own home directory. You can +use `~USER' to stand for USER's home directory. - If MODE is zero the current orientation state is queried and - nothing is changed. + "Tilde expansion" is the process of converting these abbreviations +to the directory names that they stand for. - The `fwide' function returns a negative value, zero, or a positive - value if the stream is narrow, not at all, or wide oriented - respectively. + Tilde expansion applies to the `~' plus all following characters up +to whitespace or a slash. It takes place only at the beginning of a +word, and only if none of the characters to be transformed is quoted in +any way. - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. + Plain `~' uses the value of the environment variable `HOME' as the +proper home directory name. `~' followed by a user name uses +`getpwname' to look up that user in the user database, and uses +whatever directory is recorded there. Thus, `~' followed by your own +name can give different results from plain `~', if the value of `HOME' +is not really your home directory. - It is generally a good idea to orient a stream as early as possible. -This can prevent surprise especially for the standard streams `stdin', -`stdout', and `stderr'. If some library function in some situations -uses one of these streams and this use orients the stream in a -different way the rest of the application expects it one might end up -with hard to reproduce errors. Remember that no errors are signal if -the streams are used incorrectly. Leaving a stream unoriented after -creation is normally only necessary for library functions which create -streams which can be used in different contexts. + +File: libc.info, Node: Variable Substitution, Prev: Tilde Expansion, Up: Word Expansion - When writing code which uses streams and which can be used in -different contexts it is important to query the orientation of the -stream before using it (unless the rules of the library interface -demand a specific orientation). The following little, silly function -illustrates this. +Details of Variable Substitution +-------------------------------- - void - print_f (FILE *fp) - { - if (fwide (fp, 0) > 0) - /* Positive return value means wide orientation. */ - fputwc (L'f', fp); - else - fputc ('f', fp); - } + Part of ordinary shell syntax is the use of `$VARIABLE' to +substitute the value of a shell variable into a command. This is called +"variable substitution", and it is one part of doing word expansion. - Note that in this case the function `print_f' decides about the -orientation of the stream if it was unoriented before (will not happen -if the advise above is followed). + There are two basic ways you can write a variable reference for +substitution: - The encoding used for the `wchar_t' values is unspecified and the -user must not make any assumptions about it. For I/O of `wchar_t' -values this means that it is impossible to write these values directly -to the stream. This is not what follows from the ISO C locale model -either. What happens instead is that the bytes read from or written to -the underlying media are first converted into the internal encoding -chosen by the implementation for `wchar_t'. The external encoding is -determined by the `LC_CTYPE' category of the current locale or by the -`ccs' part of the mode specification given to `fopen', `fopen64', -`freopen', or `freopen64'. How and when the conversion happens is -unspecified and it happens invisible to the user. +`${VARIABLE}' + If you write braces around the variable name, then it is completely + unambiguous where the variable name ends. You can concatenate + additional letters onto the end of the variable value by writing + them immediately after the close brace. For example, `${foo}s' + expands into `tractors'. - Since a stream is created in the unoriented state it has at that -point no conversion associated with it. The conversion which will be -used is determined by the `LC_CTYPE' category selected at the time the -stream is oriented. If the locales are changed at the runtime this -might produce surprising results unless one pays attention. This is -just another good reason to orient the stream explicitly as soon as -possible, perhaps with a call to `fwide'. +`$VARIABLE' + If you do not put braces around the variable name, then the + variable name consists of all the alphanumeric characters and + underscores that follow the `$'. The next punctuation character + ends the variable name. Thus, `$foo-bar' refers to the variable + `foo' and expands into `tractor-bar'. - -File: libc.info, Node: Simple Output, Next: Character Input, Prev: Streams and I18N, Up: I/O on Streams + When you use braces, you can also use various constructs to modify +the value that is substituted, or test it in various ways. -Simple Output by Characters or Lines -==================================== +`${VARIABLE:-DEFAULT}' + Substitute the value of VARIABLE, but if that is empty or + undefined, use DEFAULT instead. - This section describes functions for performing character- and -line-oriented output. +`${VARIABLE:=DEFAULT}' + Substitute the value of VARIABLE, but if that is empty or + undefined, use DEFAULT instead and set the variable to DEFAULT. - These narrow streams functions are declared in the header file -`stdio.h' and the wide stream functions in `wchar.h'. +`${VARIABLE:?MESSAGE}' + If VARIABLE is defined and not empty, substitute its value. - - Function: int fputc (int C, FILE *STREAM) - The `fputc' function converts the character C to type `unsigned - char', and writes it to the stream STREAM. `EOF' is returned if a - write error occurs; otherwise the character C is returned. + Otherwise, print MESSAGE as an error message on the standard error + stream, and consider word expansion a failure. - - Function: wint_t fputwc (wchar_t WC, FILE *STREAM) - The `fputwc' function writes the wide character WC to the stream - STREAM. `WEOF' is returned if a write error occurs; otherwise the - character WC is returned. +`${VARIABLE:+REPLACEMENT}' + Substitute REPLACEMENT, but only if VARIABLE is defined and + nonempty. Otherwise, substitute nothing for this construct. - - Function: int fputc_unlocked (int C, FILE *STREAM) - The `fputc_unlocked' function is equivalent to the `fputc' - function except that it does not implicitly lock the stream. +`${#VARIABLE}' + Substitute a numeral which expresses in base ten the number of + characters in the value of VARIABLE. `${#foo}' stands for `7', + because `tractor' is seven characters. - - Function: wint_t fputwc_unlocked (wint_t WC, FILE *STREAM) - The `fputwc_unlocked' function is equivalent to the `fputwc' - function except that it does not implicitly lock the stream. + These variants of variable substitution let you remove part of the +variable's value before substituting it. The PREFIX and SUFFIX are not +mere strings; they are wildcard patterns, just like the patterns that +you use to match multiple file names.

It - is provided for compatibility with SVID, but we recommend you use - `fwrite' instead (*note Block Input/Output::). + Before you can read or write the contents of a file, you must +establish a connection or communications channel to the file. This +process is called "opening" the file. You can open a file for reading, +writing, or both. + + The connection to an open file is represented either as a stream or +as a file descriptor. You pass this as an argument to the functions +that do the actual read or write operations, to tell them which file to +operate on. Certain functions expect streams, and others are designed +to operate on file descriptors. + + When you have finished reading to or writing from the file, you can +terminate the connection by "closing" the file. Once you have closed a +stream or file descriptor, you cannot do any more input or output +operations on it. + +* Menu: + +* Streams and File Descriptors:: The GNU Library provides two ways + to access the contents of files. +* File Position:: The number of bytes from the + beginning of the file.  -File: libc.info, Node: Character Input, Next: Line Input, Prev: Simple Output, Up: I/O on Streams +File: libc.info, Node: Streams and File Descriptors, Next: File Position, Up: I/O Concepts -Character Input -=============== +Streams and File Descriptors +---------------------------- - This section describes functions for performing character-oriented -input. These narrow streams functions are declared in the header file -`stdio.h' and the wide character functions are declared in `wchar.h'. + When you want to do input or output to a file, you have a choice of +two basic mechanisms for representing the connection between your +program and the file: file descriptors and streams. File descriptors +are represented as objects of type `int', while streams are represented +as `FILE *' objects. - These functions return an `int' or `wint_t' value (for narrow and -wide stream functions respectively) that is either a character of -input, or the special value `EOF'/`WEOF' (usually -1). For the narrow -stream functions it is important to store the result of these functions -in a variable of type `int' instead of `char', even when you plan to -use it only as a character. Storing `EOF' in a `char' variable -truncates its value to the size of a character, so that it is no longer -distinguishable from the valid character `(char) -1'. So always use an -`int' for the result of `getc' and friends, and check for `EOF' after -the call; once you've verified that the result is not `EOF', you can be -sure that it will fit in a `char' variable without loss of information. + File descriptors provide a primitive, low-level interface to input +and output operations. Both file descriptors and streams can represent +a connection to a device (such as a terminal), or a pipe or socket for +communicating with another process, as well as a normal file. But, if +you want to do control operations that are specific to a particular kind +of device, you must use a file descriptor; there are no facilities to +use streams in this way. You must also use file descriptors if your +program needs to do input or output in special modes, such as +nonblocking (or polled) input (*note File Status Flags::). - - Function: int fgetc (FILE *STREAM) - This function reads the next character as an `unsigned char' from - the stream STREAM and returns its value, converted to an `int'. - If an end-of-file condition or read error occurs, `EOF' is - returned instead. + Streams provide a higher-level interface, layered on top of the +primitive file descriptor facilities. The stream interface treats all +kinds of files pretty much alike--the sole exception being the three +styles of buffering that you can choose (*note Stream Buffering::). - - Function: wint_t fgetwc (FILE *STREAM) - This function reads the next wide character from the stream STREAM - and returns its value. If an end-of-file condition or read error - occurs, `WEOF' is returned instead. + The main advantage of using the stream interface is that the set of +functions for performing actual input and output operations (as opposed +to control operations) on streams is much richer and more powerful than +the corresponding facilities for file descriptors. The file descriptor +interface provides only simple functions for transferring blocks of +characters, but the stream interface also provides powerful formatted +input and output functions (`printf' and `scanf') as well as functions +for character- and line-oriented input and output. - - Function: int fgetc_unlocked (FILE *STREAM) - The `fgetc_unlocked' function is equivalent to the `fgetc' - function except that it does not implicitly lock the stream. + Since streams are implemented in terms of file descriptors, you can +extract the file descriptor from a stream and perform low-level +operations directly on the file descriptor. You can also initially open +a connection as a file descriptor and then make a stream associated with +that file descriptor. - - Function: wint_t fgetwc_unlocked (FILE *STREAM) - The `fgetwc_unlocked' function is equivalent to the `fgetwc' - function except that it does not implicitly lock the stream. + In general, you should stick with using streams rather than file +descriptors, unless there is some specific operation you want to do that +can only be done on a file descriptor. If you are a beginning +programmer and aren't sure what functions to use, we suggest that you +concentrate on the formatted input functions (*note Formatted Input::) +and formatted output functions (*note Formatted Output::). - This function is a GNU extension. + If you are concerned about portability of your programs to systems +other than GNU, you should also be aware that file descriptors are not +as portable as streams. You can expect any system running ISO C to +support streams, but non-GNU systems may not support file descriptors at +all, or may only implement a subset of the GNU functions that operate on +file descriptors. Most of the file descriptor functions in the GNU +library are included in the POSIX.1 standard, however. - - Function: int getc (FILE *STREAM) - This is just like `fgetc', except that it is permissible (and - typical) for it to be implemented as a macro that evaluates the - STREAM argument more than once. `getc' is often highly optimized, - so it is usually the best function to use to read a single - character. + +File: libc.info, Node: File Position, Prev: Streams and File Descriptors, Up: I/O Concepts - - Function: wint_t getwc (FILE *STREAM) - This is just like `fgetwc', except that it is permissible for it to - be implemented as a macro that evaluates the STREAM argument more - than once. `getwc' can be highly optimized, so it is usually the - best function to use to read a single wide character. +File Position +------------- - - Function: int getc_unlocked (FILE *STREAM) - The `getc_unlocked' function is equivalent to the `getc' function - except that it does not implicitly lock the stream. + One of the attributes of an open file is its "file position" that +keeps track of where in the file the next character is to be read or +written. In the GNU system, and all POSIX.1 systems, the file position +is simply an integer representing the number of bytes from the beginning +of the file. - - Function: wint_t getwc_unlocked (FILE *STREAM) - The `getwc_unlocked' function is equivalent to the `getwc' - function except that it does not implicitly lock the stream. + The file position is normally set to the beginning of the file when +it is opened, and each time a character is read or written, the file +position is incremented. In other words, access to the file is normally +"sequential". - This function is a GNU extension. + Ordinary files permit read or write operations at any position within +the file. Some other kinds of files may also permit this. Files which +do permit this are sometimes referred to as "random-access" files. You +can change the file position using the `fseek' function on a stream +(*note File Positioning::) or the `lseek' function on a file descriptor +(*note I/O Primitives::). If you try to change the file position on a +file that doesn't support random access, you get the `ESPIPE' error. - - Function: int getchar (void) - The `getchar' function is equivalent to `getc' with `stdin' as the - value of the STREAM argument. + Streams and descriptors that are opened for "append access" are +treated specially for output: output to such files is _always_ appended +sequentially to the _end_ of the file, regardless of the file position. +However, the file position is still used to control where in the file +reading is done. - - Function: wint_t getwchar (void) - The `getwchar' function is equivalent to `getwc' with `stdin' as - the value of the STREAM argument. + If you think about it, you'll realize that several programs can read +a given file at the same time. In order for each program to be able to +read the file at its own pace, each program must have its own file +pointer, which is not affected by anything the other programs do. - - Function: int getchar_unlocked (void) - The `getchar_unlocked' function is equivalent to the `getchar' - function except that it does not implicitly lock the stream. + In fact, each opening of a file creates a separate file position. +Thus, if you open a file twice even in the same program, you get two +streams or descriptors with independent file positions. - - Function: wint_t getwchar_unlocked (void) - The `getwchar_unlocked' function is equivalent to the `getwchar' - function except that it does not implicitly lock the stream. + By contrast, if you open a descriptor and then duplicate it to get +another descriptor, these two descriptors share the same file position: +changing the file position of one descriptor will affect the other. - This function is a GNU extension. + +File: libc.info, Node: File Names, Prev: I/O Concepts, Up: I/O Overview - Here is an example of a function that does input using `fgetc'. It -would work just as well using `getc' instead, or using `getchar ()' -instead of `fgetc (stdin)'. The code would also work the same for the -wide character stream functions. +File Names +========== - int - y_or_n_p (const char *question) - { - fputs (question, stdout); - while (1) - { - int c, answer; - /* Write a space to separate answer from question. */ - fputc (' ', stdout); - /* Read the first character of the line. - This should be the answer character, but might not be. */ - c = tolower (fgetc (stdin)); - answer = c; - /* Discard rest of input line. */ - while (c != '\n' && c != EOF) - c = fgetc (stdin); - /* Obey the answer if it was valid. */ - if (answer == 'y') - return 1; - if (answer == 'n') - return 0; - /* Answer was invalid: ask for valid answer. */ - fputs ("Please answer y or n:", stdout); - } - } + In order to open a connection to a file, or to perform other +operations such as deleting a file, you need some way to refer to the +file. Nearly all files have names that are strings--even files which +are actually devices such as tape drives or terminals. These strings +are called "file names". You specify the file name to say which file +you want to open or operate on. - - Function: int getw (FILE *STREAM) - This function reads a word (that is, an `int') from STREAM. It's - provided for compatibility with SVID. We recommend you use - `fread' instead (*note Block Input/Output::). Unlike `getc', any - `int' value could be a valid result. `getw' returns `EOF' when it - encounters end-of-file or an error, but there is no way to - distinguish this from an input word with value -1. + This section describes the conventions for file names and how the +operating system works with them. + +* Menu: + +* Directories:: Directories contain entries for files. +* File Name Resolution:: A file name specifies how to look up a file. +* File Name Errors:: Error conditions relating to file names. +* File Name Portability:: File name portability and syntax issues.  -File: libc.info, Node: Line Input, Next: Unreading, Prev: Character Input, Up: I/O on Streams +File: libc.info, Node: Directories, Next: File Name Resolution, Up: File Names -Line-Oriented Input -=================== +Directories +----------- - Since many programs interpret input on the basis of lines, it is -convenient to have functions to read a line of text from a stream. + In order to understand the syntax of file names, you need to +understand how the file system is organized into a hierarchy of +directories. - Standard C has functions to do this, but they aren't very safe: null -characters and even (for `gets') long lines can confuse them. So the -GNU library provides the nonstandard `getline' function that makes it -easy to read lines reliably. + A "directory" is a file that contains information to associate other +files with names; these associations are called "links" or "directory +entries". Sometimes, people speak of "files in a directory", but in +reality, a directory only contains pointers to files, not the files +themselves. - Another GNU extension, `getdelim', generalizes `getline'. It reads -a delimited record, defined as everything through the next occurrence -of a specified delimiter character. + The name of a file contained in a directory entry is called a "file +name component". In general, a file name consists of a sequence of one +or more such components, separated by the slash character (`/'). A +file name which is just one component names a file with respect to its +directory. A file name with multiple components names a directory, and +then a file in that directory, and so on. - All these functions are declared in `stdio.h'. + Some other documents, such as the POSIX standard, use the term +"pathname" for what we call a file name, and either "filename" or +"pathname component" for what this manual calls a file name component. +We don't use this terminology because a "path" is something completely +different (a list of directories to search), and we think that +"pathname" used for something else will confuse users. We always use +"file name" and "file name component" (or sometimes just "component", +where the context is obvious) in GNU documentation. Some macros use +the POSIX terminology in their names, such as `PATH_MAX'. These macros +are defined by the POSIX standard, so we cannot change their names. - - Function: ssize_t getline (char **LINEPTR, size_t *N, FILE *STREAM) - This function reads an entire line from STREAM, storing the text - (including the newline and a terminating null character) in a - buffer and storing the buffer address in `*LINEPTR'. + You can find more detailed information about operations on +directories in *Note File System Interface::. - Before calling `getline', you should place in `*LINEPTR' the - address of a buffer `*N' bytes long, allocated with `malloc'. If - this buffer is long enough to hold the line, `getline' stores the - line in this buffer. Otherwise, `getline' makes the buffer bigger - using `realloc', storing the new buffer address back in `*LINEPTR' - and the increased size back in `*N'. *Note Unconstrained - Allocation::. + +File: libc.info, Node: File Name Resolution, Next: File Name Errors, Prev: Directories, Up: File Names - If you set `*LINEPTR' to a null pointer, and `*N' to zero, before - the call, then `getline' allocates the initial buffer for you by - calling `malloc'. +File Name Resolution +-------------------- - In either case, when `getline' returns, `*LINEPTR' is a `char *' - which points to the text of the line. + A file name consists of file name components separated by slash +(`/') characters. On the systems that the GNU C library supports, +multiple successive `/' characters are equivalent to a single `/' +character. - When `getline' is successful, it returns the number of characters - read (including the newline, but not including the terminating - null). This value enables you to distinguish null characters that - are part of the line from the null character inserted as a - terminator. + The process of determining what file a file name refers to is called +"file name resolution". This is performed by examining the components +that make up a file name in left-to-right order, and locating each +successive component in the directory named by the previous component. +Of course, each of the files that are referenced as directories must +actually exist, be directories instead of regular files, and have the +appropriate permissions to be accessible by the process; otherwise the +file name resolution fails. - This function is a GNU extension, but it is the recommended way to - read lines from a stream. The alternative standard functions are - unreliable. + If a file name begins with a `/', the first component in the file +name is located in the "root directory" of the process (usually all +processes on the system have the same root directory). Such a file name +is called an "absolute file name". - If an error occurs or end of file is reached without any bytes - read, `getline' returns `-1'. + Otherwise, the first component in the file name is located in the +current working directory (*note Working Directory::). This kind of +file name is called a "relative file name". - - Function: ssize_t getdelim (char **LINEPTR, size_t *N, int - DELIMITER, FILE *STREAM) - This function is like `getline' except that the character which - tells it to stop reading is not necessarily newline. The argument - DELIMITER specifies the delimiter character; `getdelim' keeps - reading until it sees that character (or end of file). + The file name components `.' ("dot") and `..' ("dot-dot") have +special meanings. Every directory has entries for these file name +components. The file name component `.' refers to the directory +itself, while the file name component `..' refers to its "parent +directory" (the directory that contains the link for the directory in +question). As a special case, `..' in the root directory refers to the +root directory itself, since it has no parent; thus `/..' is the same +as `/'. - The text is stored in LINEPTR, including the delimiter character - and a terminating null. Like `getline', `getdelim' makes LINEPTR - bigger if it isn't big enough. + Here are some examples of file names: - `getline' is in fact implemented in terms of `getdelim', just like - this: +`/a' + The file named `a', in the root directory. - ssize_t - getline (char **lineptr, size_t *n, FILE *stream) - { - return getdelim (lineptr, n, '\n', stream); - } +`/a/b' + The file named `b', in the directory named `a' in the root + directory. - - Function: char * fgets (char *S, int COUNT, FILE *STREAM) - The `fgets' function reads characters from the stream STREAM up to - and including a newline character and stores them in the string S, - adding a null character to mark the end of the string. You must - supply COUNT characters worth of space in S, but the number of - characters read is at most COUNT - 1. The extra character space - is used to hold the null character at the end of the string. +`a' + The file named `a', in the current working directory. - If the system is already at end of file when you call `fgets', then - the contents of the array S are unchanged and a null pointer is - returned. A null pointer is also returned if a read error occurs. - Otherwise, the return value is the pointer S. +`/a/./b' + This is the same as `/a/b'. - *Warning:* If the input data has a null character, you can't tell. - So don't use `fgets' unless you know the data cannot contain a - null. Don't use it to read files edited by the user because, if - the user inserts a null character, you should either handle it - properly or print a clear error message. We recommend using - `getline' instead of `fgets'. +`./a' + The file named `a', in the current working directory. - - Function: wchar_t * fgetws (wchar_t *WS, int COUNT, FILE *STREAM) - The `fgetws' function reads wide characters from the stream STREAM - up to and including a newline character and stores them in the - string WS, adding a null wide character to mark the end of the - string. You must supply COUNT wide characters worth of space in - WS, but the number of characters read is at most COUNT - 1. The - extra character space is used to hold the null wide character at - the end of the string. +`../a' + The file named `a', in the parent directory of the current working + directory. - If the system is already at end of file when you call `fgetws', - then the contents of the array WS are unchanged and a null pointer - is returned. A null pointer is also returned if a read error - occurs. Otherwise, the return value is the pointer WS. + A file name that names a directory may optionally end in a `/'. You +can specify a file name of `/' to refer to the root directory, but the +empty string is not a meaningful file name. If you want to refer to +the current working directory, use a file name of `.' or `./'. - *Warning:* If the input data has a null wide character (which are - null bytes in the input stream), you can't tell. So don't use - `fgetws' unless you know the data cannot contain a null. Don't use - it to read files edited by the user because, if the user inserts a - null character, you should either handle it properly or print a - clear error message. + Unlike some other operating systems, the GNU system doesn't have any +built-in support for file types (or extensions) or file versions as part +of its file name syntax. Many programs and utilities use conventions +for file names--for example, files containing C source code usually +have names suffixed with `.c'--but there is nothing in the file system +itself that enforces this kind of convention. - - Function: char * fgets_unlocked (char *S, int COUNT, FILE *STREAM) - The `fgets_unlocked' function is equivalent to the `fgets' - function except that it does not implicitly lock the stream. + +File: libc.info, Node: File Name Errors, Next: File Name Portability, Prev: File Name Resolution, Up: File Names - This function is a GNU extension. +File Name Errors +---------------- - - Function: wchar_t * fgetws_unlocked (wchar_t *WS, int COUNT, FILE - *STREAM) - The `fgetws_unlocked' function is equivalent to the `fgetws' - function except that it does not implicitly lock the stream. + Functions that accept file name arguments usually detect these +`errno' error conditions relating to the file name syntax or trouble +finding the named file.

If `gets' encounters a read error or end-of-file, it - returns a null pointer; otherwise it returns S. +`ENAMETOOLONG' + This error is used when either the total length of a file name is + greater than `PATH_MAX', or when an individual file name component + has a length greater than `NAME_MAX'. *Note Limits for Files::. - *Warning:* The `gets' function is *very dangerous* because it - provides no protection against overflowing the string S.

In addition to varying restrictions on the +length of file names and what characters can validly appear in a file +name, different operating systems use different conventions and syntax +for concepts such as structured directories and file types or +extensions. Some concepts such as file versions might be supported in +some operating systems and not by others. + + The POSIX.1 standard allows implementations to put additional +restrictions on file name syntax, concerning what characters are +permitted in file names and on the length of file name and file name +component strings. However, in the GNU system, you do not need to worry +about these restrictions; any character except the null character is +permitted in a file name string, and there are no limits on the length +of file name strings.  -File: libc.info, Node: Unreading Idea, Next: How Unread, Up: Unreading +File: libc.info, Node: I/O on Streams, Next: Low-Level I/O, Prev: I/O Overview, Up: Top -What Unreading Means --------------------- +Input/Output on Streams +*********************** - Here is a pictorial explanation of unreading. Suppose you have a -stream reading a file that contains just six characters, the letters -`foobar'. Suppose you have read three characters so far. The -situation looks like this: + This chapter describes the functions for creating streams and +performing input and output operations on them. As discussed in *Note +I/O Overview::, a stream is a fairly abstract, high-level concept +representing a communications channel to a file, device, or process. - f o o b a r - ^ +* Menu: -so the next input character will be `b'. +* Streams:: About the data type representing a stream. +* Standard Streams:: Streams to the standard input and output + devices are created for you. +* Opening Streams:: How to create a stream to talk to a file. +* Closing Streams:: Close a stream when you are finished with it. +* Streams and Threads:: Issues with streams in threaded programs. +* Streams and I18N:: Streams in internationalized applications. +* Simple Output:: Unformatted output by characters and lines. +* Character Input:: Unformatted input by characters and words. +* Line Input:: Reading a line or a record from a stream. +* Unreading:: Peeking ahead/pushing back input just read. +* Block Input/Output:: Input and output operations on blocks of data. +* Formatted Output:: `printf' and related functions. +* Customizing Printf:: You can define new conversion specifiers for + `printf' and friends. +* Formatted Input:: `scanf' and related functions. +* EOF and Errors:: How you can tell if an I/O error happens. +* Error Recovery:: What you can do about errors. +* Binary Streams:: Some systems distinguish between text files + and binary files. +* File Positioning:: About random-access streams. +* Portable Positioning:: Random access on peculiar ISO C systems. +* Stream Buffering:: How to control buffering of streams. +* Other Kinds of Streams:: Streams that do not necessarily correspond + to an open file. +* Formatted Messages:: Print strictly formatted messages. - If instead of reading `b' you unread the letter `o', you get a -situation like this: + +File: libc.info, Node: Streams, Next: Standard Streams, Up: I/O on Streams - f o o b a r - | - o-- - ^ +Streams +======= -so that the next input characters will be `o' and `b'. + For historical reasons, the type of the C data structure that +represents a stream is called `FILE' rather than "stream". Since most +of the library functions deal with objects of type `FILE *', sometimes +the term "file pointer" is also used to mean "stream". This leads to +unfortunate confusion over terminology in many books on C. This +manual, however, is careful to use the terms "file" and "stream" only +in the technical sense. - If you unread `9' instead of `o', you get this situation: + The `FILE' type is declared in the header file `stdio.h'. - f o o b a r - | - 9-- - ^ + - Data Type: FILE + This is the data type used to represent stream objects. A `FILE' + object holds all of the internal state information about the + connection to the associated file, including such things as the + file position indicator and buffering information. Each stream + also has error and end-of-file status indicators that can be + tested with the `ferror' and `feof' functions; see *Note EOF and + Errors::. -so that the next input characters will be `9' and `b'. + `FILE' objects are allocated and managed internally by the +input/output library functions. Don't try to create your own objects of +type `FILE'; let the library do it. Your programs should deal only +with pointers to these objects (that is, `FILE *' values) rather than +the objects themselves.  -File: libc.info, Node: How Unread, Prev: Unreading Idea, Up: Unreading +File: libc.info, Node: Standard Streams, Next: Opening Streams, Prev: Streams, Up: I/O on Streams -Using `ungetc' To Do Unreading ------------------------------- +Standard Streams +================ - The function to unread a character is called `ungetc', because it -reverses the action of `getc'. + When the `main' function of your program is invoked, it already has +three predefined streams open and available for use. These represent +the "standard" input and output channels that have been established for +the process. - - Function: int ungetc (int C, FILE *STREAM) - The `ungetc' function pushes back the character C onto the input - stream STREAM. So the next input from STREAM will read C before - anything else. + These streams are declared in the header file `stdio.h'. - If C is `EOF', `ungetc' does nothing and just returns `EOF'. This - lets you call `ungetc' with the return value of `getc' without - needing to check for an error from `getc'. + - Variable: FILE * stdin + The "standard input" stream, which is the normal source of input + for the program. - The character that you push back doesn't have to be the same as - the last character that was actually read from the stream. In - fact, it isn't necessary to actually read any characters from the - stream before unreading them with `ungetc'! But that is a strange - way to write a program; usually `ungetc' is used only to unread a - character that was just read from the same stream. + - Variable: FILE * stdout + The "standard output" stream, which is used for normal output from + the program. - The GNU C library only supports one character of pushback--in other - words, it does not work to call `ungetc' twice without doing input - in between. Other systems might let you push back multiple - characters; then reading from the stream retrieves the characters - in the reverse order that they were pushed. + - Variable: FILE * stderr + The "standard error" stream, which is used for error messages and + diagnostics issued by the program. - Pushing back characters doesn't alter the file; only the internal - buffering for the stream is affected. If a file positioning - function (such as `fseek', `fseeko' or `rewind'; *note File - Positioning::) is called, any pending pushed-back characters are - discarded. + In the GNU system, you can specify what files or processes +correspond to these streams using the pipe and redirection facilities +provided by the shell. (The primitives shells use to implement these +facilities are described in *Note File System Interface::.) Most other +operating systems provide similar mechanisms, but the details of how to +use them can vary. - Unreading a character on a stream that is at end of file clears the - end-of-file indicator for the stream, because it makes the - character of input available. After you read that character, - trying to read again will encounter end of file. + In the GNU C library, `stdin', `stdout', and `stderr' are normal +variables which you can set just like any others. For example, to +redirect the standard output to a file, you could do: - - Function: wint_t ungetwc (wint_t WC, FILE *STREAM) - The `ungetwc' function behaves just like `ungetc' just that it - pushes back a wide character. + fclose (stdout); + stdout = fopen ("standard-output-file", "w"); - Here is an example showing the use of `getc' and `ungetc' to skip -over whitespace characters. When this function reaches a -non-whitespace character, it unreads that character to be seen again on -the next read operation on the stream. + Note however, that in other systems `stdin', `stdout', and `stderr' +are macros that you cannot assign to in the normal way. But you can +use `freopen' to get the effect of closing one and reopening it. *Note +Opening Streams::. - #include - #include - - void - skip_whitespace (FILE *stream) - { - int c; - do - /* No need to check for `EOF' because it is not - `isspace', and `ungetc' ignores `EOF'. */ - c = getc (stream); - while (isspace (c)); - ungetc (c, stream); - } + The three streams `stdin', `stdout', and `stderr' are not unoriented +at program start (*note Streams and I18N::).  -File: libc.info, Node: Block Input/Output, Next: Formatted Output, Prev: Unreading, Up: I/O on Streams - -Block Input/Output -================== +File: libc.info, Node: Opening Streams, Next: Closing Streams, Prev: Standard Streams, Up: I/O on Streams - This section describes how to do input and output operations on -blocks of data. You can use these functions to read and write binary -data, as well as to read and write text in fixed-size blocks instead of -by characters or lines. +Opening Streams +=============== - Binary files are typically used to read and write blocks of data in -the same format as is used to represent the data in a running program. -In other words, arbitrary blocks of memory--not just character or string -objects--can be written to a binary file, and meaningfully read in -again by the same program. + Opening a file with the `fopen' function creates a new stream and +establishes a connection between the stream and a file. This may +involve creating a new file. - Storing data in binary form is often considerably more efficient than -using the formatted I/O functions. Also, for floating-point numbers, -the binary form avoids possible loss of precision in the conversion -process. On the other hand, binary files can't be examined or modified -easily using many standard file utilities (such as text editors), and -are not portable between different implementations of the language, or -different kinds of computers. + Everything described in this section is declared in the header file +`stdio.h'. - These functions are declared in `stdio.h'. + - Function: FILE * fopen (const char *FILENAME, const char *OPENTYPE) + The `fopen' function opens a stream for I/O to the file FILENAME, + and returns a pointer to the stream. - - Function: size_t fread (void *DATA, size_t SIZE, size_t COUNT, FILE - *STREAM) - This function reads up to COUNT objects of size SIZE into the - array DATA, from the stream STREAM. It returns the number of - objects actually read, which might be less than COUNT if a read - error occurs or the end of the file is reached. This function - returns a value of zero (and doesn't read anything) if either SIZE - or COUNT is zero. + The OPENTYPE argument is a string that controls how the file is + opened and specifies attributes of the resulting stream. It must + begin with one of the following sequences of characters: - If `fread' encounters end of file in the middle of an object, it - returns the number of complete objects read, and discards the - partial object. Therefore, the stream remains at the actual end - of the file. + `r' + Open an existing file for reading only. - - Function: size_t fread_unlocked (void *DATA, size_t SIZE, size_t - COUNT, FILE *STREAM) - The `fread_unlocked' function is equivalent to the `fread' - function except that it does not implicitly lock the stream. + `w' + Open the file for writing only. If the file already exists, + it is truncated to zero length. Otherwise a new file is + created. - This function is a GNU extension. + `a' + Open a file for append access; that is, writing at the end of + file only. If the file already exists, its initial contents + are unchanged and output to the stream is appended to the end + of the file. Otherwise, a new, empty file is created. - - Function: size_t fwrite (const void *DATA, size_t SIZE, size_t - COUNT, FILE *STREAM) - This function writes up to COUNT objects of size SIZE from the - array DATA, to the stream STREAM. The return value is normally - COUNT, if the call succeeds. Any other value indicates some sort - of error, such as running out of space. + `r+' + Open an existing file for both reading and writing. The + initial contents of the file are unchanged and the initial + file position is at the beginning of the file. - - Function: size_t fwrite_unlocked (const void *DATA, size_t SIZE, - size_t COUNT, FILE *STREAM) - The `fwrite_unlocked' function is equivalent to the `fwrite' - function except that it does not implicitly lock the stream. + `w+' + Open a file for both reading and writing. If the file + already exists, it is truncated to zero length. Otherwise, a + new file is created. - This function is a GNU extension. + `a+' + Open or create file for both reading and appending. If the + file exists, its initial contents are unchanged. Otherwise, + a new file is created. The initial file position for reading + is at the beginning of the file, but output is always + appended to the end of the file. - -File: libc.info, Node: Formatted Output, Next: Customizing Printf, Prev: Block Input/Output, Up: I/O on Streams + As you can see, `+' requests a stream that can do both input and + output. The ISO standard says that when using such a stream, you + must call `fflush' (*note Stream Buffering::) or a file positioning + function such as `fseek' (*note File Positioning::) when switching + from reading to writing or vice versa. Otherwise, internal buffers + might not be emptied properly. The GNU C library does not have + this limitation; you can do arbitrary reading and writing + operations on a stream in whatever order. -Formatted Output -================ + Additional characters may appear after these to specify flags for + the call. Always put the mode (`r', `w+', etc.) first; that is + the only part you are guaranteed will be understood by all systems. - The functions described in this section (`printf' and related -functions) provide a convenient way to perform formatted output. You -call `printf' with a "format string" or "template string" that -specifies how to format the values of the remaining arguments. + The GNU C library defines one additional character for use in + OPENTYPE: the character `x' insists on creating a new file--if a + file FILENAME already exists, `fopen' fails rather than opening + it. If you use `x' you are guaranteed that you will not clobber + an existing file. This is equivalent to the `O_EXCL' option to + the `open' function (*note Opening and Closing Files::). - Unless your program is a filter that specifically performs line- or -character-oriented processing, using `printf' or one of the other -related functions described in this section is usually the easiest and -most concise way to perform output. These functions are especially -useful for printing error messages, tables of data, and the like. + The character `b' in OPENTYPE has a standard meaning; it requests + a binary stream rather than a text stream. But this makes no + difference in POSIX systems (including the GNU system). If both + `+' and `b' are specified, they can appear in either order. *Note + Binary Streams::. -* Menu: + If the OPENTYPE string contains the sequence `,ccs=STRING' then + STRING is taken as the name of a coded character set and `fopen' + will mark the stream as wide-oriented which appropriate conversion + functions in place to convert from and to the character set STRING + is place. Any other stream is opened initially unoriented and the + orientation is decided with the first file operation. If the + first operation is a wide character operation, the stream is not + only marked as wide-oriented, also the conversion functions to + convert to the coded character set used for the current locale are + loaded. This will not change anymore from this point on even if + the locale selected for the `LC_CTYPE' category is changed. -* Formatted Output Basics:: Some examples to get you started. -* Output Conversion Syntax:: General syntax of conversion - specifications. -* Table of Output Conversions:: Summary of output conversions and - what they do. -* Integer Conversions:: Details about formatting of integers. -* Floating-Point Conversions:: Details about formatting of - floating-point numbers. -* Other Output Conversions:: Details about formatting of strings, - characters, pointers, and the like. -* Formatted Output Functions:: Descriptions of the actual functions. -* Dynamic Output:: Functions that allocate memory for the output. -* Variable Arguments Output:: `vprintf' and friends. -* Parsing a Template String:: What kinds of args does a given template - call for? -* Example of Parsing:: Sample program using `parse_printf_format'. + Any other characters in OPENTYPE are simply ignored. They may be + meaningful in other systems. - -File: libc.info, Node: Formatted Output Basics, Next: Output Conversion Syntax, Up: Formatted Output + If the open fails, `fopen' returns a null pointer. -Formatted Output Basics ------------------------ + When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a + 32 bit machine this function is in fact `fopen64' since the LFS + interface replaces transparently the old interface. - The `printf' function can be used to print any number of arguments. -The template string argument you supply in a call provides information -not only about the number of additional arguments, but also about their -types and what style should be used for printing them. + You can have multiple streams (or file descriptors) pointing to the +same file open at the same time. If you do only input, this works +straightforwardly, but you must be careful if any output streams are +included. *Note Stream/Descriptor Precautions::. This is equally true +whether the streams are in one program (not usual) or in several +programs (which can easily happen). It may be advantageous to use the +file locking facilities to avoid simultaneous access. *Note File +Locks::. - Ordinary characters in the template string are simply written to the -output stream as-is, while "conversion specifications" introduced by a -`%' character in the template cause subsequent arguments to be -formatted and written to the output stream. For example, + - Function: FILE * fopen64 (const char *FILENAME, const char *OPENTYPE) + This function is similar to `fopen' but the stream it returns a + pointer for is opened using `open64'. Therefore this stream can be + used even on files larger then 2^31 bytes on 32 bit machines. - int pct = 37; - char filename[] = "foo.txt"; - printf ("Processing of `%s' is %d%% finished.\nPlease be patient.\n", - filename, pct); + Please note that the return type is still `FILE *'. There is no + special `FILE' type for the LFS interface. -produces output like + If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 + bits machine this function is available under the name `fopen' and + so transparently replaces the old interface. - Processing of `foo.txt' is 37% finished. - Please be patient. + - Macro: int FOPEN_MAX + The value of this macro is an integer constant expression that + represents the minimum number of streams that the implementation + guarantees can be open simultaneously. You might be able to open + more than this many streams, but that is not guaranteed. The + value of this constant is at least eight, which includes the three + standard streams `stdin', `stdout', and `stderr'. In POSIX.1 + systems this value is determined by the `OPEN_MAX' parameter; + *note General Limits::. In BSD and GNU, it is controlled by the + `RLIMIT_NOFILE' resource limit; *note Limits on Resources::. - This example shows the use of the `%d' conversion to specify that an -`int' argument should be printed in decimal notation, the `%s' -conversion to specify printing of a string argument, and the `%%' -conversion to print a literal `%' character. + - Function: FILE * freopen (const char *FILENAME, const char + *OPENTYPE, FILE *STREAM) + This function is like a combination of `fclose' and `fopen'. It + first closes the stream referred to by STREAM, ignoring any errors + that are detected in the process. (Because errors are ignored, + you should not use `freopen' on an output stream if you have + actually done any output using the stream.) Then the file named by + FILENAME is opened with mode OPENTYPE as for `fopen', and + associated with the same stream object STREAM. - There are also conversions for printing an integer argument as an -unsigned value in octal, decimal, or hexadecimal radix (`%o', `%u', or -`%x', respectively); or as a character value (`%c'). + If the operation fails, a null pointer is returned; otherwise, + `freopen' returns STREAM. - Floating-point numbers can be printed in normal, fixed-point notation -using the `%f' conversion or in exponential notation using the `%e' -conversion. The `%g' conversion uses either `%e' or `%f' format, -depending on what is more appropriate for the magnitude of the -particular number. + `freopen' has traditionally been used to connect a standard stream + such as `stdin' with a file of your own choice. This is useful in + programs in which use of a standard stream for certain purposes is + hard-coded. In the GNU C library, you can simply close the + standard streams and open new ones with `fopen'. But other + systems lack this ability, so using `freopen' is more portable. - You can control formatting more precisely by writing "modifiers" -between the `%' and the character that indicates which conversion to -apply. These slightly alter the ordinary behavior of the conversion. -For example, most conversion specifications permit you to specify a -minimum field width and a flag indicating whether you want the result -left- or right-justified within the field. + When the sources are compiling with `_FILE_OFFSET_BITS == 64' on a + 32 bit machine this function is in fact `freopen64' since the LFS + interface replaces transparently the old interface. - The specific flags and modifiers that are permitted and their -interpretation vary depending on the particular conversion. They're all -described in more detail in the following sections. Don't worry if this -all seems excessively complicated at first; you can almost always get -reasonable free-format output without using any of the modifiers at all. -The modifiers are mostly used to make the output look "prettier" in -tables. + - Function: FILE * freopen64 (const char *FILENAME, const char + *OPENTYPE, FILE *STREAM) + This function is similar to `freopen'. The only difference is that + on 32 bit machine the stream returned is able to read beyond the + 2^31 bytes limits imposed by the normal interface. It should be + noted that the stream pointed to by STREAM need not be opened + using `fopen64' or `freopen64' since its mode is not important for + this function. - -File: libc.info, Node: Output Conversion Syntax, Next: Table of Output Conversions, Prev: Formatted Output Basics, Up: Formatted Output + If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 + bits machine this function is available under the name `freopen' + and so transparently replaces the old interface. -Output Conversion Syntax ------------------------- + In some situations it is useful to know whether a given stream is +available for reading or writing. This information is normally not +available and would have to be remembered separately. Solaris +introduced a few functions to get this information from the stream +descriptor and these functions are also available in the GNU C library. - This section provides details about the precise syntax of conversion -specifications that can appear in a `printf' template string. + - Function: int __freadable (FILE *STREAM) + The `__freadable' function determines whether the stream STREAM + was opened to allow reading. In this case the return value is + nonzero. For write-only streams the function returns zero. - Characters in the template string that are not part of a conversion -specification are printed as-is to the output stream. Multibyte -character sequences (*note Character Set Handling::) are permitted in a -template string. + This function is declared in `stdio_ext.h'. - The conversion specifications in a `printf' template string have the -general form: + - Function: int __fwritable (FILE *STREAM) + The `__fwritable' function determines whether the stream STREAM + was opened to allow writing. In this case the return value is + nonzero. For read-only streams the function returns zero. - % [ PARAM-NO $] FLAGS WIDTH [ . PRECISION ] TYPE CONVERSION + This function is declared in `stdio_ext.h'. - For example, in the conversion specifier `%-10.8ld', the `-' is a -flag, `10' specifies the field width, the precision is `8', the letter -`l' is a type modifier, and `d' specifies the conversion style. (This -particular type specifier says to print a `long int' argument in -decimal notation, with a minimum of 8 digits left-justified in a field -at least 10 characters wide.) + For slightly different kind of problems there are two more functions. +They provide even finer-grained information. - In more detail, output conversion specifications consist of an -initial `%' character followed in sequence by: + - Function: int __freading (FILE *STREAM) + The `__freading' function determines whether the stream STREAM was + last read from or whether it is opened read-only. In this case + the return value is nonzero, otherwise it is zero. Determining + whether a stream opened for reading and writing was last used for + writing allows to draw conclusions about the content about the + buffer, among other things. - * An optional specification of the parameter used for this format. - Normally the parameters to the `printf' function are assigned to - the formats in the order of appearance in the format string. But - in some situations (such as message translation) this is not - desirable and this extension allows an explicit parameter to be - specified. + This function is declared in `stdio_ext.h'. - The PARAM-NO part of the format must be an integer in the range of - 1 to the maximum number of arguments present to the function call. - Some implementations limit this number to a certainly upper - bound. The exact limit can be retrieved by the following constant. + - Function: int __fwriting (FILE *STREAM) + The `__fwriting' function determines whether the stream STREAM was + last written to or whether it is opened write-only. In this case + the return value is nonzero, otherwise it is zero. - - Macro: NL_ARGMAX - The value of `ARGMAX' is the maximum value allowed for the - specification of an positional parameter in a `printf' call. - The actual value in effect at runtime can be retrieved by - using `sysconf' using the `_SC_NL_ARGMAX' parameter *note - Sysconf Definition::. + This function is declared in `stdio_ext.h'. - Some system have a quite low limit such as 9 for System V - systems. The GNU C library has no real limit. + +File: libc.info, Node: Closing Streams, Next: Streams and Threads, Prev: Opening Streams, Up: I/O on Streams - If any of the formats has a specification for the parameter - position all of them in the format string shall have one. - Otherwise the behavior is undefined. +Closing Streams +=============== - * Zero or more "flag characters" that modify the normal behavior of - the conversion specification. + When a stream is closed with `fclose', the connection between the +stream and the file is canceled. After you have closed a stream, you +cannot perform any additional operations on it. - * An optional decimal integer specifying the "minimum field width". - If the normal conversion produces fewer characters than this, the - field is padded with spaces to the specified width. This is a - _minimum_ value; if the normal conversion produces more characters - than this, the field is _not_ truncated. Normally, the output is - right-justified within the field. + - Function: int fclose (FILE *STREAM) + This function causes STREAM to be closed and the connection to the + corresponding file to be broken. Any buffered output is written + and any buffered input is discarded. The `fclose' function returns + a value of `0' if the file was closed successfully, and `EOF' if + an error was detected. - You can also specify a field width of `*'. This means that the - next argument in the argument list (before the actual value to be - printed) is used as the field width. The value must be an `int'. - If the value is negative, this means to set the `-' flag (see - below) and to use the absolute value as the field width. + It is important to check for errors when you call `fclose' to close + an output stream, because real, everyday errors can be detected at + this time. For example, when `fclose' writes the remaining + buffered output, it might get an error because the disk is full. + Even if you know the buffer is empty, errors can still occur when + closing a file if you are using NFS. - * An optional "precision" to specify the number of digits to be - written for the numeric conversions. If the precision is - specified, it consists of a period (`.') followed optionally by a - decimal integer (which defaults to zero if omitted). + The function `fclose' is declared in `stdio.h'. - You can also specify a precision of `*'. This means that the next - argument in the argument list (before the actual value to be - printed) is used as the precision. The value must be an `int', - and is ignored if it is negative. If you specify `*' for both the - field width and precision, the field width argument precedes the - precision argument. Other C library versions may not recognize - this syntax. + To close all streams currently available the GNU C Library provides +another function. - * An optional "type modifier character", which is used to specify the - data type of the corresponding argument if it differs from the - default type. (For example, the integer conversions assume a type - of `int', but you can specify `h', `l', or `L' for other integer - types.) + - Function: int fcloseall (void) + This function causes all open streams of the process to be closed + and the connection to corresponding files to be broken. All + buffered data is written and any buffered input is discarded. The + `fcloseall' function returns a value of `0' if all the files were + closed successfully, and `EOF' if an error was detected. - * A character that specifies the conversion to be applied. + This function should be used only in special situations, e.g., + when an error occurred and the program must be aborted. Normally + each single stream should be closed separately so that problems + with individual streams can be identified. It is also problematic + since the standard streams (*note Standard Streams::) will also be + closed. - The exact options that are permitted and how they are interpreted -vary between the different conversion specifiers. See the descriptions -of the individual conversions for information about the particular -options that they use. + The function `fcloseall' is declared in `stdio.h'. - With the `-Wformat' option, the GNU C compiler checks calls to -`printf' and related functions. It examines the format string and -verifies that the correct number and types of arguments are supplied. -There is also a GNU C syntax to tell the compiler that a function you -write uses a `printf'-style format string. *Note Declaring Attributes -of Functions: (gcc.info)Function Attributes, for more information. + If the `main' function to your program returns, or if you call the +`exit' function (*note Normal Termination::), all open streams are +automatically closed properly.

But the programmer must +be aware of a the possible complications. It is important to know about +these also if the program one writes never use threads since the design +and implementation of many stream functions is heavily influenced by the +requirements added by multi-threaded programming. -`0' - Pad the field with zeros instead of spaces. The zeros are placed - after any indication of sign or base. This flag is ignored if the - `-' flag is also specified, or if a precision is specified. + The POSIX standard requires that by default the stream operations are +atomic. I.e., issuing two stream operations for the same stream in two +threads at the same time will cause the operations to be executed as if +they were issued sequentially. The buffer operations performed while +reading or writing are protected from other uses of the same stream. To +do this each stream has an internal lock object which has to be +(implicitly) acquired before any work can be done. - If a precision is supplied, it specifies the minimum number of -digits to appear; leading zeros are produced if necessary. If you -don't specify a precision, the number is printed with as many digits as -it needs. If you convert a value of zero with an explicit precision of -zero, then no characters at all are produced. + But there are situations where this is not enough and there are also +situations where this is not wanted. The implicit locking is not enough +if the program requires more than one stream function call to happen +atomically. One example would be if an output line a program wants to +generate is created by several function calls. The functions by +themselves would ensure only atomicity of their own operation, but not +atomicity over all the function calls. For this it is necessary to +perform the stream locking in the application code. - Without a type modifier, the corresponding argument is treated as an -`int' (for the signed conversions `%i' and `%d') or `unsigned int' (for -the unsigned conversions `%o', `%u', `%x', and `%X'). Recall that -since `printf' and friends are variadic, any `char' and `short' -arguments are automatically converted to `int' by the default argument -promotions. For arguments of other integer types, you can use these -modifiers: + - Function: void flockfile (FILE *STREAM) + The `flockfile' function acquires the internal locking object + associated with the stream STREAM. This ensures that no other + thread can explicitly through `flockfile'/`ftrylockfile' or + implicit through a call of a stream function lock the stream. The + thread will block until the lock is acquired. An explicit call to + `funlockfile' has to be used to release the lock. -`hh' - Specifies that the argument is a `signed char' or `unsigned char', - as appropriate. A `char' argument is converted to an `int' or - `unsigned int' by the default argument promotions anyway, but the - `h' modifier says to convert it back to a `char' again. + - Function: int ftrylockfile (FILE *STREAM) + The `ftrylockfile' function tries to acquire the internal locking + object associated with the stream STREAM just like `flockfile'. + But unlike `flockfile' this function does not block if the lock is + not available. `ftrylockfile' returns zero if the lock was + successfully acquired. Otherwise the stream is locked by another + thread. - This modifier was introduced in ISO C99. + - Function: void funlockfile (FILE *STREAM) + The `funlockfile' function releases the internal locking object of + the stream STREAM. The stream must have been locked before by a + call to `flockfile' or a successful call of `ftrylockfile'. The + implicit locking performed by the stream operations do not count. + The `funlockfile' function does not return an error status and the + behavior of a call for a stream which is not locked by the current + thread is undefined. -`h' - Specifies that the argument is a `short int' or `unsigned short - int', as appropriate. A `short' argument is converted to an `int' - or `unsigned int' by the default argument promotions anyway, but - the `h' modifier says to convert it back to a `short' again. + The following example shows how the functions above can be used to +generate an output line atomically even in multi-threaded applications +(yes, the same job could be done with one `fprintf' call but it is +sometimes not possible): -`j' - Specifies that the argument is a `intmax_t' or `uintmax_t', as - appropriate. + FILE *fp; + { + ... + flockfile (fp); + fputs ("This is test number ", fp); + fprintf (fp, "%d\n", test); + funlockfile (fp) + } - This modifier was introduced in ISO C99. + Without the explicit locking it would be possible for another thread +to use the stream FP after the `fputs' call return and before `fprintf' +was called with the result that the number does not follow the word +`number'. -`l' - Specifies that the argument is a `long int' or `unsigned long - int', as appropriate. Two `l' characters is like the `L' - modifier, below. + From this description it might already be clear that the locking +objects in streams are no simple mutexes. Since locking the same +stream twice in the same thread is allowed the locking objects must be +equivalent to recursive mutexes. These mutexes keep track of the owner +and the number of times the lock is acquired. The same number of +`funlockfile' calls by the same threads is necessary to unlock the +stream completely. For instance: - If used with `%c' or `%s' the corresponding parameter is - considered as a wide character or wide character string - respectively. This use of `l' was introduced in Amendment 1 to - ISO C90. + void + foo (FILE *fp) + { + ftrylockfile (fp); + fputs ("in foo\n", fp); + /* This is very wrong!!! */ + funlockfile (fp); + } -`L' -`ll' -`q' - Specifies that the argument is a `long long int'. (This type is - an extension supported by the GNU C compiler. On systems that - don't support extra-long integers, this is the same as `long int'.) + It is important here that the `funlockfile' function is only called +if the `ftrylockfile' function succeeded in locking the stream. It is +therefore always wrong to ignore the result of `ftrylockfile'. And it +makes no sense since otherwise one would use `flockfile'. The result +of code like that above is that either `funlockfile' tries to free a +stream that hasn't been locked by the current thread or it frees the +stream prematurely. The code should look like this: - The `q' modifier is another name for the same thing, which comes - from 4.4 BSD; a `long long int' is sometimes called a "quad" `int'. + void + foo (FILE *fp) + { + if (ftrylockfile (fp) == 0) + { + fputs ("in foo\n", fp); + funlockfile (fp); + } + } -`t' - Specifies that the argument is a `ptrdiff_t'. + Now that we covered why it is necessary to have these locking it is +necessary to talk about situations when locking is unwanted and what can +be done. The locking operations (explicit or implicit) don't come for +free. Even if a lock is not taken the cost is not zero. The operations +which have to be performed require memory operations that are safe in +multi-processor environments. With the many local caches involved in +such systems this is quite costly. So it is best to avoid the locking +completely if it is not needed - because the code in question is never +used in a context where two or more threads may use a stream at a time. +This can be determined most of the time for application code; for +library code which can be used in many contexts one should default to be +conservative and use locking. - This modifier was introduced in ISO C99. + There are two basic mechanisms to avoid locking. The first is to use +the `_unlocked' variants of the stream operations. The POSIX standard +defines quite a few of those and the GNU library adds a few more. +These variants of the functions behave just like the functions with the +name without the suffix except that they do not lock the stream. Using +these functions is very desirable since they are potentially much +faster. This is not only because the locking operation itself is +avoided. More importantly, functions like `putc' and `getc' are very +simple and traditionally (before the introduction of threads) were +implemented as macros which are very fast if the buffer is not empty. +With the addition of locking requirements these functions are no longer +implemented as macros since they would would expand to too much code. +But these macros are still available with the same functionality under +the new names `putc_unlocked' and `getc_unlocked'. This possibly huge +difference of speed also suggests the use of the `_unlocked' functions +even if locking is required. The difference is that the locking then +has to be performed in the program: -`z' -`Z' - Specifies that the argument is a `size_t'. + void + foo (FILE *fp, char *buf) + { + flockfile (fp); + while (*buf != '/') + putc_unlocked (*buf++, fp); + funlockfile (fp); + } - `z' was introduced in ISO C99. `Z' is a GNU extension predating - this addition and should not be used in new code. + If in this example the `putc' function would be used and the +explicit locking would be missing the `putc' function would have to +acquire the lock in every call, potentially many times depending on when +the loop terminates. Writing it the way illustrated above allows the +`putc_unlocked' macro to be used which means no locking and direct +manipulation of the buffer of the stream. - Here is an example. Using the template string: + A second way to avoid locking is by using a non-standard function +which was introduced in Solaris and is available in the GNU C library +as well. - "|%5d|%-5d|%+5d|%+-5d|% 5d|%05d|%5.0d|%5.2d|%d|\n" + - Function: int __fsetlocking (FILE *STREAM, int TYPE) + The `__fsetlocking' function can be used to select whether the + stream operations will implicitly acquire the locking object of the + stream STREAM. By default this is done but it can be disabled and + reinstated using this function. There are three values defined + for the TYPE parameter. -to print numbers using the different options for the `%d' conversion -gives results like: + `FSETLOCKING_INTERNAL' + The stream `stream' will from now on use the default internal + locking. Every stream operation with exception of the + `_unlocked' variants will implicitly lock the stream. - | 0|0 | +0|+0 | 0|00000| | 00|0| - | 1|1 | +1|+1 | 1|00001| 1| 01|1| - | -1|-1 | -1|-1 | -1|-0001| -1| -01|-1| - |100000|100000|+100000| 100000|100000|100000|100000|100000| + `FSETLOCKING_BYCALLER' + After the `__fsetlocking' function returns the user is + responsible for locking the stream. None of the stream + operations will implicitly do this anymore until the state is + set back to `FSETLOCKING_INTERNAL'. - In particular, notice what happens in the last case where the number -is too large to fit in the minimum field width specified. + `FSETLOCKING_QUERY' + `__fsetlocking' only queries the current locking state of the + stream. The return value will be `FSETLOCKING_INTERNAL' or + `FSETLOCKING_BYCALLER' depending on the state. - Here are some more examples showing how unsigned integers print under -various format options, using the template string: + The return value of `__fsetlocking' is either + `FSETLOCKING_INTERNAL' or `FSETLOCKING_BYCALLER' depending on the + state of the stream before the call. - "|%5u|%5o|%5x|%5X|%#5o|%#5x|%#5X|%#10.8x|\n" + This function and the values for the TYPE parameter are declared + in `stdio_ext.h'. - | 0| 0| 0| 0| 0| 0x0| 0X0|0x00000000| - | 1| 1| 1| 1| 01| 0x1| 0X1|0x00000001| - |100000|303240|186a0|186A0|0303240|0x186a0|0X186A0|0x000186a0| + This function is especially useful when program code has to be used +which is written without knowledge about the `_unlocked' functions (or +if the programmer was too lazy to use them).  -File: libc.info, Node: Floating-Point Conversions, Next: Other Output Conversions, Prev: Integer Conversions, Up: Formatted Output - -Floating-Point Conversions --------------------------- - - This section discusses the conversion specifications for -floating-point numbers: the `%f', `%e', `%E', `%g', and `%G' -conversions. +File: libc.info, Node: Streams and I18N, Next: Simple Output, Prev: Streams and Threads, Up: I/O on Streams - The `%f' conversion prints its argument in fixed-point notation, -producing output of the form [`-']DDD`.'DDD, where the number of digits -following the decimal point is controlled by the precision you specify. +Streams in Internationalized Applications +========================================= - The `%e' conversion prints its argument in exponential notation, -producing output of the form [`-']D`.'DDD`e'[`+'|`-']DD. Again, the -number of digits following the decimal point is controlled by the -precision. The exponent always contains at least two digits. The `%E' -conversion is similar but the exponent is marked with the letter `E' -instead of `e'. + ISO C90 introduced the new type `wchar_t' to allow handling larger +character sets. What was missing was a possibility to output strings +of `wchar_t' directly. One had to convert them into multibyte strings +using `mbstowcs' (there was no `mbsrtowcs' yet) and then use the normal +stream functions. While this is doable it is very cumbersome since +performing the conversions is not trivial and greatly increases program +complexity and size. - The `%g' and `%G' conversions print the argument in the style of -`%e' or `%E' (respectively) if the exponent would be less than -4 or -greater than or equal to the precision; otherwise they use the `%f' -style. Trailing zeros are removed from the fractional portion of the -result and a decimal-point character appears only if it is followed by -a digit. + The Unix standard early on (I think in XPG4.2) introduced two +additional format specifiers for the `printf' and `scanf' families of +functions. Printing and reading of single wide characters was made +possible using the `%C' specifier and wide character strings can be +handled with `%S'. These modifiers behave just like `%c' and `%s' only +that they expect the corresponding argument to have the wide character +type and that the wide character and string are transformed into/from +multibyte strings before being used. - The `%a' and `%A' conversions are meant for representing -floating-point numbers exactly in textual form so that they can be -exchanged as texts between different programs and/or machines. The -numbers are represented is the form [`-']`0x'H`.'HHH`p'[`+'|`-']DD. At -the left of the decimal-point character exactly one digit is print. -This character is only `0' if the number is denormalized. Otherwise -the value is unspecified; it is implementation dependent how many bits -are used. The number of hexadecimal digits on the right side of the -decimal-point character is equal to the precision. If the precision is -zero it is determined to be large enough to provide an exact -representation of the number (or it is large enough to distinguish two -adjacent values if the `FLT_RADIX' is not a power of 2, *note Floating -Point Parameters::). For the `%a' conversion lower-case characters are -used to represent the hexadecimal number and the prefix and exponent -sign are printed as `0x' and `p' respectively. Otherwise upper-case -characters are used and `0X' and `P' are used for the representation of -prefix and exponent string. The exponent to the base of two is printed -as a decimal number using at least one digit but at most as many digits -as necessary to represent the value exactly. + This was a beginning but it is still not good enough. Not always is +it desirable to use `printf' and `scanf'. The other, smaller and +faster functions cannot handle wide characters. Second, it is not +possible to have a format string for `printf' and `scanf' consisting of +wide characters. The result is that format strings would have to be +generated if they have to contain non-basic characters. - If the value to be printed represents infinity or a NaN, the output -is [`-']`inf' or `nan' respectively if the conversion specifier is -`%a', `%e', `%f', or `%g' and it is [`-']`INF' or `NAN' respectively if -the conversion is `%A', `%E', or `%G'. + In the Amendment 1 to ISO C90 a whole new set of functions was added +to solve the problem. Most of the stream functions got a counterpart +which take a wide character or wide character string instead of a +character or string respectively. The new functions operate on the +same streams (like `stdout'). This is different from the model of the +C++ runtime library where separate streams for wide and normal I/O are +used. - The following flags can be used to modify the behavior: + Being able to use the same stream for wide and normal operations +comes with a restriction: a stream can be used either for wide +operations or for normal operations. Once it is decided there is no +way back. Only a call to `freopen' or `freopen64' can reset the +"orientation". The orientation can be decided in three ways: -`-' - Left-justify the result in the field. Normally the result is - right-justified. + * If any of the normal character functions is used (this includes the + `fread' and `fwrite' functions) the stream is marked as not wide + oriented. -`+' - Always include a plus or minus sign in the result. + * If any of the wide character functions is used the stream is + marked as wide oriented. -` ' - If the result doesn't start with a plus or minus sign, prefix it - with a space instead. Since the `+' flag ensures that the result - includes a sign, this flag is ignored if you supply both of them. + * The `fwide' function can be used to set the orientation either way. -`#' - Specifies that the result should always include a decimal point, - even if no digits follow it. For the `%g' and `%G' conversions, - this also forces trailing zeros after the decimal point to be left - in place where they would otherwise be removed. + It is important to never mix the use of wide and not wide operations +on a stream. There are no diagnostics issued. The application behavior +will simply be strange or the application will simply crash. The +`fwide' function can help avoiding this. -`'' - Separate the digits of the integer part of the result into groups - as specified by the locale specified for the `LC_NUMERIC' category; - *note General Numeric::. This flag is a GNU extension. + - Function: int fwide (FILE *STREAM, int MODE) + The `fwide' function can be used to set and query the state of the + orientation of the stream STREAM. If the MODE parameter has a + positive value the streams get wide oriented, for negative values + narrow oriented. It is not possible to overwrite previous + orientations with `fwide'. I.e., if the stream STREAM was already + oriented before the call nothing is done. -`0' - Pad the field with zeros instead of spaces; the zeros are placed - after any sign. This flag is ignored if the `-' flag is also - specified. + If MODE is zero the current orientation state is queried and + nothing is changed. - The precision specifies how many digits follow the decimal-point -character for the `%f', `%e', and `%E' conversions. For these -conversions, the default precision is `6'. If the precision is -explicitly `0', this suppresses the decimal point character entirely. -For the `%g' and `%G' conversions, the precision specifies how many -significant digits to print. Significant digits are the first digit -before the decimal point, and all the digits after it. If the -precision is `0' or not specified for `%g' or `%G', it is treated like -a value of `1'. If the value being printed cannot be expressed -accurately in the specified number of digits, the value is rounded to -the nearest number that fits. + The `fwide' function returns a negative value, zero, or a positive + value if the stream is narrow, not at all, or wide oriented + respectively. - Without a type modifier, the floating-point conversions use an -argument of type `double'. (By the default argument promotions, any -`float' arguments are automatically converted to `double'.) The -following type modifier is supported: + This function was introduced in Amendment 1 to ISO C90 and is + declared in `wchar.h'. -`L' - An uppercase `L' specifies that the argument is a `long double'. + It is generally a good idea to orient a stream as early as possible. +This can prevent surprise especially for the standard streams `stdin', +`stdout', and `stderr'. If some library function in some situations +uses one of these streams and this use orients the stream in a +different way the rest of the application expects it one might end up +with hard to reproduce errors. Remember that no errors are signal if +the streams are used incorrectly. Leaving a stream unoriented after +creation is normally only necessary for library functions which create +streams which can be used in different contexts. - Here are some examples showing how numbers print using the various -floating-point conversions. All of the numbers were printed using this -template string: + When writing code which uses streams and which can be used in +different contexts it is important to query the orientation of the +stream before using it (unless the rules of the library interface +demand a specific orientation).

These narrow streams functions are declared in the header file +`stdio.h' and the wide character functions are declared in `wchar.h'. - *Warning:* The `sprintf' function can be *dangerous* because it - can potentially output more characters than can fit in the - allocation size of the string S. Remember that the field width - given in a conversion specification is only a _minimum_ value. + These functions return an `int' or `wint_t' value (for narrow and +wide stream functions respectively) that is either a character of +input, or the special value `EOF'/`WEOF' (usually -1). For the narrow +stream functions it is important to store the result of these functions +in a variable of type `int' instead of `char', even when you plan to +use it only as a character. Storing `EOF' in a `char' variable +truncates its value to the size of a character, so that it is no longer +distinguishable from the valid character `(char) -1'. So always use an +`int' for the result of `getc' and friends, and check for `EOF' after +the call; once you've verified that the result is not `EOF', you can be +sure that it will fit in a `char' variable without loss of information. - To avoid this problem, you can use `snprintf' or `asprintf', - described below. + - Function: int fgetc (FILE *STREAM) + This function reads the next character as an `unsigned char' from + the stream STREAM and returns its value, converted to an `int'. + If an end-of-file condition or read error occurs, `EOF' is + returned instead. - - Function: int swprintf (wchar_t *S, size_t SIZE, const wchar_t - *TEMPLATE, ...) - This is like `wprintf', except that the output is stored in the - wide character array WS instead of written to a stream. A null - wide character is written to mark the end of the string. The SIZE - argument specifies the maximum number of characters to produce. - The trailing null character is counted towards this limit, so you - should allocate at least SIZE wide characters for the string WS. + - Function: wint_t fgetwc (FILE *STREAM) + This function reads the next wide character from the stream STREAM + and returns its value. If an end-of-file condition or read error + occurs, `WEOF' is returned instead. - The return value is the number of characters generated for the - given input, excluding the trailing null. If not all output fits - into the provided buffer a negative value is returned. You should - try again with a bigger output string. _Note:_ this is different - from how `snprintf' handles this situation. + - Function: int fgetc_unlocked (FILE *STREAM) + The `fgetc_unlocked' function is equivalent to the `fgetc' + function except that it does not implicitly lock the stream. - Note that the corresponding narrow stream function takes fewer - parameters. `swprintf' in fact corresponds to the `snprintf' - function. Since the `sprintf' function can be dangerous and should - be avoided the ISO C committee refused to make the same mistake - again and decided to not define an function exactly corresponding - to `sprintf'. + - Function: wint_t fgetwc_unlocked (FILE *STREAM) + The `fgetwc_unlocked' function is equivalent to the `fgetwc' + function except that it does not implicitly lock the stream. - - Function: int snprintf (char *S, size_t SIZE, const char *TEMPLATE, - ...) - The `snprintf' function is similar to `sprintf', except that the - SIZE argument specifies the maximum number of characters to - produce.

Here is an example of doing this: + - Function: int getc (FILE *STREAM) + This is just like `fgetc', except that it is permissible (and + typical) for it to be implemented as a macro that evaluates the + STREAM argument more than once. `getc' is often highly optimized, + so it is usually the best function to use to read a single + character. - /* Construct a message describing the value of a variable - whose name is NAME and whose value is VALUE. */ - char * - make_message (char *name, char *value) - { - /* Guess we need no more than 100 chars of space. */ - int size = 100; - char *buffer = (char *) xmalloc (size); - int nchars; - if (buffer == NULL) - return NULL; - - /* Try to print in the allocated space. */ - nchars = snprintf (buffer, size, "value of %s is %s", - name, value); - if (nchars >= size) - { - /* Reallocate buffer now that we know - how much space is needed. */ - buffer = (char *) xrealloc (buffer, nchars + 1); - - if (buffer != NULL) - /* Try again. */ - snprintf (buffer, size, "value of %s is %s", - name, value); - } - /* The last call worked, return the string. */ - return buffer; - } + - Function: wint_t getwc (FILE *STREAM) + This is just like `fgetwc', except that it is permissible for it to + be implemented as a macro that evaluates the STREAM argument more + than once. `getwc' can be highly optimized, so it is usually the + best function to use to read a single wide character. - In practice, it is often easier just to use `asprintf', below. + - Function: int getc_unlocked (FILE *STREAM) + The `getc_unlocked' function is equivalent to the `getc' function + except that it does not implicitly lock the stream. - *Attention:* In versions of the GNU C library prior to 2.1 the - return value is the number of characters stored, not including the - terminating null; unless there was not enough space in S to store - the result in which case `-1' is returned.

But there is no way to do -this in C, and it would be hard to provide a way, since at the C -language level there is no way to tell how many arguments your function -received. + Standard C has functions to do this, but they aren't very safe: null +characters and even (for `gets') long lines can confuse them. So the +GNU library provides the nonstandard `getline' function that makes it +easy to read lines reliably. - Since that method is impossible, we provide alternative functions, -the `vprintf' series, which lets you pass a `va_list' to describe "all -of my arguments after the first five." + Another GNU extension, `getdelim', generalizes `getline'. It reads +a delimited record, defined as everything through the next occurrence +of a specified delimiter character. - When it is sufficient to define a macro rather than a real function, -the GNU C compiler provides a way to do this much more easily with -macros. For example: + All these functions are declared in `stdio.h'. - #define myprintf(a, b, c, d, e, rest...) \ - printf (mytemplate , ## rest...) + - Function: ssize_t getline (char **LINEPTR, size_t *N, FILE *STREAM) + This function reads an entire line from STREAM, storing the text + (including the newline and a terminating null character) in a + buffer and storing the buffer address in `*LINEPTR'. -*Note Macros with Variable Numbers of Arguments: (gcc.info)Macro -Varargs, for details. But this is limited to macros, and does not -apply to real functions at all. + Before calling `getline', you should place in `*LINEPTR' the + address of a buffer `*N' bytes long, allocated with `malloc'. If + this buffer is long enough to hold the line, `getline' stores the + line in this buffer. Otherwise, `getline' makes the buffer bigger + using `realloc', storing the new buffer address back in `*LINEPTR' + and the increased size back in `*N'. *Note Unconstrained + Allocation::. - Before calling `vprintf' or the other functions listed in this -section, you _must_ call `va_start' (*note Variadic Functions::) to -initialize a pointer to the variable arguments. Then you can call -`va_arg' to fetch the arguments that you want to handle yourself. This -advances the pointer past those arguments. + If you set `*LINEPTR' to a null pointer, and `*N' to zero, before + the call, then `getline' allocates the initial buffer for you by + calling `malloc'. - Once your `va_list' pointer is pointing at the argument of your -choice, you are ready to call `vprintf'. That argument and all -subsequent arguments that were passed to your function are used by -`vprintf' along with the template that you specified separately. + In either case, when `getline' returns, `*LINEPTR' is a `char *' + which points to the text of the line. - In some other systems, the `va_list' pointer may become invalid -after the call to `vprintf', so you must not use `va_arg' after you -call `vprintf'. Instead, you should call `va_end' to retire the -pointer from service. However, you can safely call `va_start' on -another pointer variable and begin fetching the arguments again through -that pointer. Calling `vprintf' does not destroy the argument list of -your function, merely the particular pointer that you passed to it. + When `getline' is successful, it returns the number of characters + read (including the newline, but not including the terminating + null). This value enables you to distinguish null characters that + are part of the line from the null character inserted as a + terminator. - GNU C does not have such restrictions. You can safely continue to -fetch arguments from a `va_list' pointer after passing it to `vprintf', -and `va_end' is a no-op. (Note, however, that subsequent `va_arg' -calls will fetch the same arguments which `vprintf' previously used.) + This function is a GNU extension, but it is the recommended way to + read lines from a stream.

This function permits interpreters that provide -interfaces to `printf' to avoid passing along invalid arguments from -the user's program, which could cause a crash. + In parser programs it is often useful to examine the next character +in the input stream without removing it from the stream. This is called +"peeking ahead" at the input because your program gets a glimpse of the +input it will read next. - All the symbols described in this section are declared in the header -file `printf.h'. + Using stream I/O, you can peek ahead at input by first reading it and +then "unreading" it (also called "pushing it back" on the stream). +Unreading a character makes it available to be input again from the +stream, by the next call to `fgetc' or other input function on that +stream. - - Function: size_t parse_printf_format (const char *TEMPLATE, size_t - N, int *ARGTYPES) - This function returns information about the number and types of - arguments expected by the `printf' template string TEMPLATE. The - information is stored in the array ARGTYPES; each element of this - array describes one argument.

You can - write the expression `(argtypes[i] & PA_FLAG_MASK)' to extract - just the flag bits for an argument, or `(argtypes[i] & - ~PA_FLAG_MASK)' to extract just the basic type code. + Here is a pictorial explanation of unreading. Suppose you have a +stream reading a file that contains just six characters, the letters +`foobar'. Suppose you have read three characters so far. The +situation looks like this: - Here are symbolic constants that represent the basic types; they -stand for integer values. + f o o b a r + ^ -`PA_INT' - This specifies that the base type is `int'. +so the next input character will be `b'. -`PA_CHAR' - This specifies that the base type is `int', cast to `char'. + If instead of reading `b' you unread the letter `o', you get a +situation like this: -`PA_STRING' - This specifies that the base type is `char *', a null-terminated - string. + f o o b a r + | + o-- + ^ -`PA_POINTER' - This specifies that the base type is `void *', an arbitrary - pointer. +so that the next input characters will be `o' and `b'. -`PA_FLOAT' - This specifies that the base type is `float'. + If you unread `9' instead of `o', you get this situation: -`PA_DOUBLE' - This specifies that the base type is `double'. + f o o b a r + | + 9-- + ^ -`PA_LAST' - You can define additional base types for your own programs as - offsets from `PA_LAST'. For example, if you have data types `foo' - and `bar' with their own specialized `printf' conversions, you - could define encodings for these types as: +so that the next input characters will be `9' and `b'. - #define PA_FOO PA_LAST - #define PA_BAR (PA_LAST + 1) + +File: libc.info, Node: How Unread, Prev: Unreading Idea, Up: Unreading - Here are the flag bits that modify a basic type. They are combined -with the code for the basic type using inclusive-or. +Using `ungetc' To Do Unreading +------------------------------ -`PA_FLAG_PTR' - If this bit is set, it indicates that the encoded type is a - pointer to the base type, rather than an immediate value. For - example, `PA_INT|PA_FLAG_PTR' represents the type `int *'. + The function to unread a character is called `ungetc', because it +reverses the action of `getc'. -`PA_FLAG_SHORT' - If this bit is set, it indicates that the base type is modified - with `short'. (This corresponds to the `h' type modifier.) + - Function: int ungetc (int C, FILE *STREAM) + The `ungetc' function pushes back the character C onto the input + stream STREAM. So the next input from STREAM will read C before + anything else. -`PA_FLAG_LONG' - If this bit is set, it indicates that the base type is modified - with `long'. (This corresponds to the `l' type modifier.) + If C is `EOF', `ungetc' does nothing and just returns `EOF'. This + lets you call `ungetc' with the return value of `getc' without + needing to check for an error from `getc'. -`PA_FLAG_LONG_LONG' - If this bit is set, it indicates that the base type is modified - with `long long'. (This corresponds to the `L' type modifier.) + The character that you push back doesn't have to be the same as + the last character that was actually read from the stream. In + fact, it isn't necessary to actually read any characters from the + stream before unreading them with `ungetc'! But that is a strange + way to write a program; usually `ungetc' is used only to unread a + character that was just read from the same stream. -`PA_FLAG_LONG_DOUBLE' - This is a synonym for `PA_FLAG_LONG_LONG', used by convention with - a base type of `PA_DOUBLE' to indicate a type of `long double'. + The GNU C library only supports one character of pushback--in other + words, it does not work to call `ungetc' twice without doing input + in between. Other systems might let you push back multiple + characters; then reading from the stream retrieves the characters + in the reverse order that they were pushed. - For an example of using these facilities, see *Note Example of -Parsing::. + Pushing back characters doesn't alter the file; only the internal + buffering for the stream is affected. If a file positioning + function (such as `fseek', `fseeko' or `rewind'; *note File + Positioning::) is called, any pending pushed-back characters are + discarded. - -File: libc.info, Node: Example of Parsing, Prev: Parsing a Template String, Up: Formatted Output + Unreading a character on a stream that is at end of file clears the + end-of-file indicator for the stream, because it makes the + character of input available.

It contains the following members: + The `printf' function can be used to print any number of arguments. +The template string argument you supply in a call provides information +not only about the number of additional arguments, but also about their +types and what style should be used for printing them. - `int prec' - This is the precision specified. The value is `-1' if no - precision was specified. If the precision was given as `*', - the `printf_info' structure passed to the handler function - contains the actual value retrieved from the argument list. - But the structure passed to the arginfo function contains a - value of `INT_MIN', since the actual value is not known. + Ordinary characters in the template string are simply written to the +output stream as-is, while "conversion specifications" introduced by a +`%' character in the template cause subsequent arguments to be +formatted and written to the output stream. For example, - `int width' - This is the minimum field width specified. The value is `0' - if no width was specified. If the field width was given as - `*', the `printf_info' structure passed to the handler - function contains the actual value retrieved from the - argument list. But the structure passed to the arginfo - function contains a value of `INT_MIN', since the actual - value is not known. + int pct = 37; + char filename[] = "foo.txt"; + printf ("Processing of `%s' is %d%% finished.\nPlease be patient.\n", + filename, pct); - `wchar_t spec' - This is the conversion specifier character specified. It's - stored in the structure so that you can register the same - handler function for multiple characters, but still have a - way to tell them apart when the handler function is called. +produces output like - `unsigned int is_long_double' - This is a boolean that is true if the `L', `ll', or `q' type - modifier was specified. For integer conversions, this - indicates `long long int', as opposed to `long double' for - floating point conversions. + Processing of `foo.txt' is 37% finished. + Please be patient. - `unsigned int is_char' - This is a boolean that is true if the `hh' type modifier was - specified. + This example shows the use of the `%d' conversion to specify that an +`int' argument should be printed in decimal notation, the `%s' +conversion to specify printing of a string argument, and the `%%' +conversion to print a literal `%' character. - `unsigned int is_short' - This is a boolean that is true if the `h' type modifier was - specified. + There are also conversions for printing an integer argument as an +unsigned value in octal, decimal, or hexadecimal radix (`%o', `%u', or +`%x', respectively); or as a character value (`%c'). - `unsigned int is_long' - This is a boolean that is true if the `l' type modifier was - specified. + Floating-point numbers can be printed in normal, fixed-point notation +using the `%f' conversion or in exponential notation using the `%e' +conversion. The `%g' conversion uses either `%e' or `%f' format, +depending on what is more appropriate for the magnitude of the +particular number. - `unsigned int alt' - This is a boolean that is true if the `#' flag was specified. + You can control formatting more precisely by writing "modifiers" +between the `%' and the character that indicates which conversion to +apply. These slightly alter the ordinary behavior of the conversion. +For example, most conversion specifications permit you to specify a +minimum field width and a flag indicating whether you want the result +left- or right-justified within the field. - `unsigned int space' - This is a boolean that is true if the ` ' flag was specified. + The specific flags and modifiers that are permitted and their +interpretation vary depending on the particular conversion. They're all +described in more detail in the following sections. Don't worry if this +all seems excessively complicated at first; you can almost always get +reasonable free-format output without using any of the modifiers at all. +The modifiers are mostly used to make the output look "prettier" in +tables. - `unsigned int left' - This is a boolean that is true if the `-' flag was specified. + +File: libc.info, Node: Output Conversion Syntax, Next: Table of Output Conversions, Prev: Formatted Output Basics, Up: Formatted Output - `unsigned int showsign' - This is a boolean that is true if the `+' flag was specified. +Output Conversion Syntax +------------------------ - `unsigned int group' - This is a boolean that is true if the `'' flag was specified. + This section provides details about the precise syntax of conversion +specifications that can appear in a `printf' template string. - `unsigned int extra' - This flag has a special meaning depending on the context. It - could be used freely by the user-defined handlers but when - called from the `printf' function this variable always - contains the value `0'. + Characters in the template string that are not part of a conversion +specification are printed as-is to the output stream. Multibyte +character sequences (*note Character Set Handling::) are permitted in a +template string. - `unsigned int wide' - This flag is set if the stream is wide oriented. + The conversion specifications in a `printf' template string have the +general form: - `wchar_t pad' - This is the character to use for padding the output to the - minimum field width.

But + in some situations (such as message translation) this is not + desirable and this extension allows an explicit parameter to be + specified. - *Compatibility Note:* The interface changed in GNU libc version 2.0. -Previously the third argument was of type `va_list *'. + The PARAM-NO part of the format must be an integer in the range of + 1 to the maximum number of arguments present to the function call. + Some implementations limit this number to a certainly upper + bound. The exact limit can be retrieved by the following constant. - You should define your handler functions with a prototype like: + - Macro: NL_ARGMAX + The value of `ARGMAX' is the maximum value allowed for the + specification of an positional parameter in a `printf' call. + The actual value in effect at runtime can be retrieved by + using `sysconf' using the `_SC_NL_ARGMAX' parameter *note + Sysconf Definition::. - int FUNCTION (FILE *stream, const struct printf_info *info, - const void *const *args) + Some system have a quite low limit such as 9 for System V + systems. The GNU C library has no real limit. - The STREAM argument passed to the handler function is the stream to -which it should write output. + If any of the formats has a specification for the parameter + position all of them in the format string shall have one. + Otherwise the behavior is undefined. - The INFO argument is a pointer to a structure that contains -information about the various options that were included with the -conversion in the template string. You should not modify this structure -inside your handler function. *Note Conversion Specifier Options::, for -a description of this data structure. + * Zero or more "flag characters" that modify the normal behavior of + the conversion specification. - The ARGS is a vector of pointers to the arguments data. The number -of arguments was determined by calling the argument information -function provided by the user. + * An optional decimal integer specifying the "minimum field width". + If the normal conversion produces fewer characters than this, the + field is padded with spaces to the specified width. This is a + _minimum_ value; if the normal conversion produces more characters + than this, the field is _not_ truncated. Normally, the output is + right-justified within the field. - Your handler function should return a value just like `printf' does: -it should return the number of characters it has written, or a negative -value to indicate an error. + You can also specify a field width of `*'. This means that the + next argument in the argument list (before the actual value to be + printed) is used as the field width. The value must be an `int'. + If the value is negative, this means to set the `-' flag (see + below) and to use the absolute value as the field width. - - Data Type: printf_function - This is the data type that a handler function should have. + * An optional "precision" to specify the number of digits to be + written for the numeric conversions. If the precision is + specified, it consists of a period (`.') followed optionally by a + decimal integer (which defaults to zero if omitted). - If you are going to use `parse_printf_format' in your application, -you must also define a function to pass as the ARGINFO-FUNCTION -argument for each new conversion you install with -`register_printf_function'. + You can also specify a precision of `*'. This means that the next + argument in the argument list (before the actual value to be + printed) is used as the precision. The value must be an `int', + and is ignored if it is negative. If you specify `*' for both the + field width and precision, the field width argument precedes the + precision argument. Other C library versions may not recognize + this syntax. - You have to define these functions with a prototype like: + * An optional "type modifier character", which is used to specify the + data type of the corresponding argument if it differs from the + default type. (For example, the integer conversions assume a type + of `int', but you can specify `h', `l', or `L' for other integer + types.) - int FUNCTION (const struct printf_info *info, - size_t n, int *argtypes) + * A character that specifies the conversion to be applied. - The return value from the function should be the number of arguments -the conversion expects. The function should also fill in no more than -N elements of the ARGTYPES array with information about the types of -each of these arguments. This information is encoded using the various -`PA_' macros. (You will notice that this is the same calling -convention `parse_printf_format' itself uses.) + The exact options that are permitted and how they are interpreted +vary between the different conversion specifiers. See the descriptions +of the individual conversions for information about the particular +options that they use. - - Data Type: printf_arginfo_function - This type is used to describe functions that return information - about the number and type of arguments used by a conversion - specifier. + With the `-Wformat' option, the GNU C compiler checks calls to +`printf' and related functions.

The `%X' conversion specification is just like `%x' +except that it uses the characters `ABCDEF' as digits instead of +`abcdef'. -Formatted Input Basics ----------------------- + The following flags are meaningful: - Calls to `scanf' are superficially similar to calls to `printf' in -that arbitrary arguments are read under the control of a template -string. While the syntax of the conversion specifications in the -template is very similar to that for `printf', the interpretation of -the template is oriented more towards free-format input and simple -pattern matching, rather than fixed-field formatting. For example, -most `scanf' conversions skip over any amount of "white space" -(including spaces, tabs, and newlines) in the input file, and there is -no concept of precision for the numeric input conversions as there is -for the corresponding output conversions. Ordinarily, non-whitespace -characters in the template are expected to match characters in the -input stream exactly, but a matching failure is distinct from an input -error on the stream. +`-' + Left-justify the result in the field (instead of the normal + right-justification). - Another area of difference between `scanf' and `printf' is that you -must remember to supply pointers rather than immediate values as the -optional arguments to `scanf'; the values that are read are stored in -the objects that the pointers point to. Even experienced programmers -tend to forget this occasionally, so if your program is getting strange -errors that seem to be related to `scanf', you might want to -double-check this. +`+' + For the signed `%d' and `%i' conversions, print a plus sign if the + value is positive. - When a "matching failure" occurs, `scanf' returns immediately, -leaving the first non-matching character as the next character to be -read from the stream. The normal return value from `scanf' is the -number of values that were assigned, so you can use this to determine if -a matching error happened before all the expected values were read. +` ' + For the signed `%d' and `%i' conversions, if the result doesn't + start with a plus or minus sign, prefix it with a space character + instead. Since the `+' flag ensures that the result includes a + sign, this flag is ignored if you supply both of them. - The `scanf' function is typically used for things like reading in -the contents of tables. For example, here is a function that uses -`scanf' to initialize an array of `double': +`#' + For the `%o' conversion, this forces the leading digit to be `0', + as if by increasing the precision. For `%x' or `%X', this + prefixes a leading `0x' or `0X' (respectively) to the result. + This doesn't do anything useful for the `%d', `%i', or `%u' + conversions. Using this flag produces output which can be parsed + by the `strtoul' function (*note Parsing of Integers::) and + `scanf' with the `%i' conversion (*note Numeric Input + Conversions::). - void - readarray (double *array, int n) - { - int i; - for (i=0; i= size) + { + /* Reallocate buffer now that we know + how much space is needed. */ + buffer = (char *) xrealloc (buffer, nchars + 1); + + if (buffer != NULL) + /* Try again. */ + snprintf (buffer, size, "value of %s is %s", + name, value); + } + /* The last call worked, return the string. */ + return buffer; + } - Here is an example of using the `a' flag with the `%[...]' -conversion specification to read a "variable assignment" of the form -`VARIABLE = VALUE'. + In practice, it is often easier just to use `asprintf', below. - { - char *variable, *value; - - if (2 > scanf ("%a[a-zA-Z0-9] = %a[^\n]\n", - &variable, &value)) - { - invalid_input_error (); - return 0; - } - - ... - } + *Attention:* In versions of the GNU C library prior to 2.1 the + return value is the number of characters stored, not including the + terminating null; unless there was not enough space in S to store + the result in which case `-1' is returned.

It recognizes -the same syntax used by the `%p' output conversion for `printf' (*note -Other Output Conversions::); that is, a hexadecimal number just as the -`%x' conversion accepts. The corresponding argument should be of type -`void **'; that is, the address of a place to store a pointer. + - Function: int asprintf (char **PTR, const char *TEMPLATE, ...) + This function is similar to `sprintf', except that it dynamically + allocates a string (as with `malloc'; *note Unconstrained + Allocation::) to hold the output, instead of putting the output in + a buffer you allocate in advance. The PTR argument should be the + address of a `char *' object, and `asprintf' stores a pointer to + the newly allocated string at that location. - The resulting pointer value is not guaranteed to be valid if it was -not originally written during the same program execution that reads it -in. + The return value is the number of characters allocated for the + buffer, or less than zero if an error occurred. Usually this means + that the buffer could not be allocated. - The `%n' conversion produces the number of characters read so far by -this call. The corresponding argument should be of type `int *'. This -conversion works in the same way as the `%n' conversion for `printf'; -see *Note Other Output Conversions::, for an example. + Here is how to use `asprintf' to get the same result as the + `snprintf' example, but more easily: - The `%n' conversion is the only mechanism for determining the -success of literal matches or conversions with suppressed assignments. -If the `%n' follows the locus of a matching failure, then no value is -stored for it since `scanf' returns before processing the `%n'. If you -store `-1' in that argument slot before calling `scanf', the presence -of `-1' after `scanf' indicates an error occurred before the `%n' was -reached. + /* Construct a message describing the value of a variable + whose name is NAME and whose value is VALUE. */ + char * + make_message (char *name, char *value) + { + char *result; + if (asprintf (&result, "value of %s is %s", name, value) < 0) + return NULL; + return result; + } - Finally, the `%%' conversion matches a literal `%' character in the -input stream, without using an argument. This conversion does not -permit any flags, field width, or type modifier to be specified. + - Function: int obstack_printf (struct obstack *OBSTACK, const char + *TEMPLATE, ...) + This function is similar to `asprintf', except that it uses the + obstack OBSTACK to allocate the space. *Note Obstacks::. - -File: libc.info, Node: Formatted Input Functions, Next: Variable Arguments Input, Prev: Other Input Conversions, Up: Formatted Input + The characters are written onto the end of the current object.

Prototypes for these functions are in the header file `stdio.h'. +Variable Arguments Output Functions +----------------------------------- - - Function: int scanf (const char *TEMPLATE, ...) - The `scanf' function reads formatted input from the stream `stdin' - under the control of the template string TEMPLATE. The optional - arguments are pointers to the places which receive the resulting - values. + The functions `vprintf' and friends are provided so that you can +define your own variadic `printf'-like functions that make use of the +same internals as the built-in formatted output functions. - The return value is normally the number of successful assignments. - If an end-of-file condition is detected before any matches are - performed, including matches against whitespace and literal - characters in the template, then `EOF' is returned. + The most natural way to define such functions would be to use a +language construct to say, "Call `printf' and pass this template plus +all of my arguments after the first five." But there is no way to do +this in C, and it would be hard to provide a way, since at the C +language level there is no way to tell how many arguments your function +received. - - Function: int wscanf (const wchar_t *TEMPLATE, ...) - The `wscanf' function reads formatted input from the stream - `stdin' under the control of the template string TEMPLATE. The - optional arguments are pointers to the places which receive the - resulting values. + Since that method is impossible, we provide alternative functions, +the `vprintf' series, which lets you pass a `va_list' to describe "all +of my arguments after the first five." - The return value is normally the number of successful assignments. - If an end-of-file condition is detected before any matches are - performed, including matches against whitespace and literal - characters in the template, then `WEOF' is returned. + When it is sufficient to define a macro rather than a real function, +the GNU C compiler provides a way to do this much more easily with +macros. For example: - - Function: int fscanf (FILE *STREAM, const char *TEMPLATE, ...) - This function is just like `scanf', except that the input is read - from the stream STREAM instead of `stdin'. + #define myprintf(a, b, c, d, e, rest...) \ + printf (mytemplate , ## rest...) - - Function: int fwscanf (FILE *STREAM, const wchar_t *TEMPLATE, ...) - This function is just like `wscanf', except that the input is read - from the stream STREAM instead of `stdin'. +*Note Macros with Variable Numbers of Arguments: (gcc.info)Macro +Varargs, for details. But this is limited to macros, and does not +apply to real functions at all. - - Function: int sscanf (const char *S, const char *TEMPLATE, ...) - This is like `scanf', except that the characters are taken from the - null-terminated string S instead of from a stream. Reaching the - end of the string is treated as an end-of-file condition. + Before calling `vprintf' or the other functions listed in this +section, you _must_ call `va_start' (*note Variadic Functions::) to +initialize a pointer to the variable arguments. Then you can call +`va_arg' to fetch the arguments that you want to handle yourself. This +advances the pointer past those arguments. - The behavior of this function is undefined if copying takes place - between objects that overlap--for example, if S is also given as - an argument to receive a string read under control of the `%s', - `%S', or `%[' conversion. + Once your `va_list' pointer is pointing at the argument of your +choice, you are ready to call `vprintf'. That argument and all +subsequent arguments that were passed to your function are used by +`vprintf' along with the template that you specified separately. - - Function: int swscanf (const wchar_t *WS, const char *TEMPLATE, ...) - This is like `wscanf', except that the characters are taken from - the null-terminated string WS instead of from a stream. Reaching - the end of the string is treated as an end-of-file condition. + In some other systems, the `va_list' pointer may become invalid +after the call to `vprintf', so you must not use `va_arg' after you +call `vprintf'. Instead, you should call `va_end' to retire the +pointer from service. However, you can safely call `va_start' on +another pointer variable and begin fetching the arguments again through +that pointer. Calling `vprintf' does not destroy the argument list of +your function, merely the particular pointer that you passed to it. - The behavior of this function is undefined if copying takes place - between objects that overlap--for example, if WS is also given as - an argument to receive a string read under control of the `%s', - `%S', or `%[' conversion. + GNU C does not have such restrictions. You can safely continue to +fetch arguments from a `va_list' pointer after passing it to `vprintf', +and `va_end' is a no-op. (Note, however, that subsequent `va_arg' +calls will fetch the same arguments which `vprintf' previously used.) - -File: libc.info, Node: Variable Arguments Input, Prev: Formatted Input Functions, Up: Formatted Input + Prototypes for these functions are declared in `stdio.h'. -Variable Arguments Input Functions ----------------------------------- + - Function: int vprintf (const char *TEMPLATE, va_list AP) + This function is similar to `printf' except that, instead of taking + a variable number of arguments directly, it takes an argument list + pointer AP. - The functions `vscanf' and friends are provided so that you can -define your own variadic `scanf'-like functions that make use of the -same internals as the built-in formatted output functions.

It is advisable not to use lowercase + letters, since the ISO C standard warns that additional lowercase + letters may be standardized in future editions of the standard. - Text and binary streams differ in several ways: + The HANDLER-FUNCTION is the function called by `printf' and + friends when this conversion appears in a template string. *Note + Defining the Output Handler::, for information about how to define + a function to pass as this argument. If you specify a null + pointer, any existing handler function for SPEC is removed. - * The data read from a text stream is divided into "lines" which are - terminated by newline (`'\n'') characters, while a binary stream is - simply a long series of characters. A text stream might on some - systems fail to handle lines more than 254 characters long - (including the terminating newline character). + The ARGINFO-FUNCTION is the function called by + `parse_printf_format' when this conversion appears in a template + string. *Note Parsing a Template String::, for information about + this. - * On some systems, text files can contain only printing characters, - horizontal tab characters, and newlines, and so text streams may - not support other characters.

It contains the following members: - During I/O to an ordinary disk file, you can change the file position -whenever you wish, so as to read or write any portion of the file. Some -other kinds of files may also permit this. Files which support changing -the file position are sometimes referred to as "random-access" files. + `int prec' + This is the precision specified. The value is `-1' if no + precision was specified. If the precision was given as `*', + the `printf_info' structure passed to the handler function + contains the actual value retrieved from the argument list. + But the structure passed to the arginfo function contains a + value of `INT_MIN', since the actual value is not known. - You can use the functions in this section to examine or modify the -file position indicator associated with a stream. The symbols listed -below are declared in the header file `stdio.h'. + `int width' + This is the minimum field width specified. The value is `0' + if no width was specified. If the field width was given as + `*', the `printf_info' structure passed to the handler + function contains the actual value retrieved from the + argument list.

It's + stored in the structure so that you can register the same + handler function for multiple characters, but still have a + way to tell them apart when the handler function is called. - This function can fail if the stream doesn't support file - positioning, or if the file position can't be represented in a - `long int', and possibly for other reasons as well. If a failure - occurs, a value of `-1' is returned. + `unsigned int is_long_double' + This is a boolean that is true if the `L', `ll', or `q' type + modifier was specified. For integer conversions, this + indicates `long long int', as opposed to `long double' for + floating point conversions. - - Function: off_t ftello (FILE *STREAM) - The `ftello' function is similar to `ftell', except that it - returns a value of type `off_t'. Systems which support this type - use it to describe all file positions, unlike the POSIX - specification which uses a long int. The two are not necessarily - the same size. Therefore, using ftell can lead to problems if the - implementation is written on top of a POSIX compliant low-level - I/O implementation, and using `ftello' is preferable whenever it - is available. + `unsigned int is_char' + This is a boolean that is true if the `hh' type modifier was + specified. - If this function fails it returns `(off_t) -1'.

The value of WHENCE must be one of the constants - `SEEK_SET', `SEEK_CUR', or `SEEK_END', to indicate whether the - OFFSET is relative to the beginning of the file, the current file - position, or the end of the file, respectively. + `unsigned int showsign' + This is a boolean that is true if the `+' flag was specified. - This function returns a value of zero if the operation was - successful, and a nonzero value to indicate failure. A successful - call also clears the end-of-file indicator of STREAM and discards - any characters that were "pushed back" by the use of `ungetc'. + `unsigned int group' + This is a boolean that is true if the `'' flag was specified. - `fseek' either flushes any buffered output before setting the file - position or else remembers it so it will be written later in its - proper place in the file. + `unsigned int extra' + This flag has a special meaning depending on the context.

This is called "buffering". - - If you are writing programs that do interactive input and output -using streams, you need to understand how buffering works when you -design the user interface to your program.

While the syntax of the conversion specifications in the +template is very similar to that for `printf', the interpretation of +the template is oriented more towards free-format input and simple +pattern matching, rather than fixed-field formatting. For example, +most `scanf' conversions skip over any amount of "white space" +(including spaces, tabs, and newlines) in the input file, and there is +no concept of precision for the numeric input conversions as there is +for the corresponding output conversions. Ordinarily, non-whitespace +characters in the template are expected to match characters in the +input stream exactly, but a matching failure is distinct from an input +error on the stream. - Newly opened streams are normally fully buffered, with one -exception: a stream connected to an interactive device such as a -terminal is initially line buffered. *Note Controlling Buffering::, -for information on how to select a different kind of buffering. -Usually the automatic selection gives you the most convenient kind of -buffering for the file or device you open. + Another area of difference between `scanf' and `printf' is that you +must remember to supply pointers rather than immediate values as the +optional arguments to `scanf'; the values that are read are stored in +the objects that the pointers point to. Even experienced programmers +tend to forget this occasionally, so if your program is getting strange +errors that seem to be related to `scanf', you might want to +double-check this. - The use of line buffering for interactive devices implies that output -messages ending in a newline will appear immediately--which is usually -what you want. Output that doesn't end in a newline might or might not -show up immediately, so if you want them to appear immediately, you -should flush buffered output explicitly with `fflush', as described in -*Note Flushing Buffers::. + When a "matching failure" occurs, `scanf' returns immediately, +leaving the first non-matching character as the next character to be +read from the stream.

The values thus stored remain valid - only as long as no further output on the stream takes place. If - you do more output, you must flush the stream again to store new - values before you use them again. + You have two options for how to receive the input from these +conversions: - A null character is written at the end of the buffer.

You should + provide an argument of type `char *' or `wchar_t *' (the latter of + the `l' modifier is present). - You can move the stream's file position with `fseek' or `fseeko' - (*note File Positioning::). Moving the file position past the end - of the data already written fills the intervening space with - zeroes. + *Warning:* To make a robust program, you must make sure that the + input (plus its terminating null) cannot possibly exceed the size + of the buffer you provide. In general, the only way to do this is + to specify a maximum field width one less than the buffer size. + *If you provide the buffer, always specify a maximum field width + to prevent overflow.* - Here is an example of using `open_memstream': + * Ask `scanf' to allocate a big enough buffer, by specifying the `a' + flag character.

It also does not skip over initial whitespace characters. It +reads precisely the next N characters, and fails if it cannot get that +many. Since there is always a maximum field width with `%c' (whether +specified, or 1 by default), you can always prevent overflow by making +the buffer long enough. - This program produces the following output: + If the format is `%lc' or `%C' the function stores wide characters +which are converted using the conversion determined at the time the +stream was opened from the external byte stream.

This starts an object in the obstack and makes it grow - as data is written (*note Growing Objects::). + *Warning:* If you do not specify a field width for `%s', then the +number of characters read is limited only by where the next whitespace +character appears. This almost certainly means that invalid input can +make your program crash--which is a bug. - Calling `fflush' on this stream updates the current size of the - object to match the amount of data that has been written. After a - call to `fflush', you can examine the object temporarily. + The `%ls' and `%S' format are handled just like `%s' except that the +external byte sequence is converted using the conversion associated +with the stream to wide characters with their own encoding. A width or +precision specified with the format do not directly determine how many +bytes are read from the stream since they measure wide characters. But +an upper limit can be computed by multiplying the value of the width or +precision by `MB_CUR_MAX'. - You can move the file position of an obstack stream with `fseek' or - `fseeko' (*note File Positioning::). Moving the file position past - the end of the data written fills the intervening space with zeros. + To read in characters that belong to an arbitrary set of your choice, +use the `%[' conversion. You specify the set between the `[' character +and a following `]' character, using the same syntax used in regular +expressions. As special cases: - To make the object permanent, update the obstack with `fflush', and - then use `obstack_finish' to finalize the object and get its - address. The following write to the stream starts a new object in - the obstack, and later writes add to that object until you do - another `fflush' and `obstack_finish'. + * A literal `]' character can be specified as the first character of + the set. - But how do you find out how long the object is? You can get the - length in bytes by calling `obstack_object_size' (*note Status of - an Obstack::), or you can null-terminate the object like this: + * An embedded `-' character (that is, one that is not the first or + last character of the set) is used to specify a range of + characters. - obstack_1grow (OBSTACK, 0); + * If a caret character `^' immediately follows the initial `[', then + the set of allowed input characters is the everything _except_ the + characters listed. - Whichever one you do, you must do it _before_ calling - `obstack_finish'.

It is up to you to define a data type to use -for the cookie. The stream functions in the library never refer -directly to its contents, and they don't even know what the type is; -they record its address with type `void *'. + A GNU extension to formatted input lets you safely read a string +with no maximum size. Using this feature, you don't supply a buffer; +instead, `scanf' allocates a buffer big enough to hold the data and +gives you its address. To use this feature, write `a' as a flag +character, as in `%as' or `%a[0-9a-z]'. - To implement a custom stream, you must specify _how_ to fetch or -store the data in the specified place. You do this by defining "hook -functions" to read, write, change "file position", and close the -stream. All four of these functions will be passed the stream's cookie -so they can tell where to fetch or store the data. The library -functions don't know what's inside the cookie, but your functions will -know. + The pointer argument you supply for where to store the input should +have type `char **'. The `scanf' function allocates a buffer and +stores its address in the word that the argument points to. You should +free the buffer with `free' when you no longer need it. - When you create a custom stream, you must specify the cookie pointer, -and also the four hook functions stored in a structure of type -`cookie_io_functions_t'. + Here is an example of using the `a' flag with the `%[...]' +conversion specification to read a "variable assignment" of the form +`VARIABLE = VALUE'. - These facilities are declared in `stdio.h'. + { + char *variable, *value; + + if (2 > scanf ("%a[a-zA-Z0-9] = %a[^\n]\n", + &variable, &value)) + { + invalid_input_error (); + return 0; + } + + ... + } - - Data Type: cookie_io_functions_t - This is a structure type that holds the functions that define the - communications protocol between the stream and its cookie.

If the - value is a null pointer instead of a function, then data - written to the stream is discarded. + This section describes the miscellaneous input conversions. - `cookie_seek_function_t *seek' - This is the function that performs the equivalent of file - positioning on the cookie. If the value is a null pointer - instead of a function, calls to `fseek' or `fseeko' on this - stream can only seek to locations within the buffer; any - attempt to seek outside the buffer will return an `ESPIPE' - error. + The `%p' conversion is used to read a pointer value. It recognizes +the same syntax used by the `%p' output conversion for `printf' (*note +Other Output Conversions::); that is, a hexadecimal number just as the +`%x' conversion accepts. The corresponding argument should be of type +`void **'; that is, the address of a place to store a pointer. - `cookie_close_function_t *close' - This function performs any appropriate cleanup on the cookie - when closing the stream.

To -select the destination the programmer can use the following two values, -bitwise OR combined if wanted, for the CLASSIFICATION parameter of -`fmtmsg': - -`MM_PRINT' - Display the message in standard error. - -`MM_CONSOLE' - Display the message on the system console. - - The erroneous piece of the system can be signalled by exactly one of -the following values which also is bitwise ORed with the CLASSIFICATION -parameter to `fmtmsg': +File: libc.info, Node: EOF and Errors, Next: Error Recovery, Prev: Formatted Input, Up: I/O on Streams -`MM_HARD' - The source of the condition is some hardware. +End-Of-File and Errors +====================== -`MM_SOFT' - The source of the condition is some software. + Many of the functions described in this chapter return the value of +the macro `EOF' to indicate unsuccessful completion of the operation. +Since `EOF' is used to report both end of file and random errors, it's +often better to use the `feof' function to check explicitly for end of +file and `ferror' to check for errors. These functions check +indicators that are part of the internal state of the stream object, +indicators set if the appropriate condition was detected by a previous +I/O operation on that stream. -`MM_FIRM' - The source of the condition is some firmware. + - Macro: int EOF + This macro is an integer value that is returned by a number of + narrow stream functions to indicate an end-of-file condition, or + some other error situation. With the GNU library, `EOF' is `-1'. + In other libraries, its value may be some other negative number. - A third component of the CLASSIFICATION parameter to `fmtmsg' can -describe the part of the system which detects the problem. This is -done by using exactly one of the following values: + This symbol is declared in `stdio.h'. -`MM_APPL' - The erroneous condition is detected by the application. + - Macro: int WEOF + This macro is an integer value that is returned by a number of wide + stream functions to indicate an end-of-file condition, or some + other error situation. With the GNU library, `WEOF' is `-1'. In + other libraries, its value may be some other negative number. -`MM_UTIL' - The erroneous condition is detected by a utility. + This symbol is declared in `wchar.h'. -`MM_OPSYS' - The erroneous condition is detected by the operating system. + - Function: int feof (FILE *STREAM) + The `feof' function returns nonzero if and only if the end-of-file + indicator for the stream STREAM is set. - A last component of CLASSIFICATION can signal the results of this -message. Exactly one of the following values can be used: + This symbol is declared in `stdio.h'. -`MM_RECOVER' - It is a recoverable error. + - Function: int feof_unlocked (FILE *STREAM) + The `feof_unlocked' function is equivalent to the `feof' function + except that it does not implicitly lock the stream. -`MM_NRECOV' - It is a non-recoverable error. + This function is a GNU extension. - - Function: int fmtmsg (long int CLASSIFICATION, const char *LABEL, - int SEVERITY, const char *TEXT, const char *ACTION, const - char *TAG) - Display a message described by its parameters on the device(s) - specified in the CLASSIFICATION parameter. The LABEL parameter - identifies the source of the message. The string should consist - of two colon separated parts where the first part has not more - than 10 and the second part not more than 14 characters. The TEXT - parameter describes the condition of the error, the ACTION - parameter possible steps to recover from the error and the TAG - parameter is a reference to the online documentation where more - information can be found. It should contain the LABEL value and a - unique identification number. + This symbol is declared in `stdio.h'. - Each of the parameters can be a special value which means this - value is to be omitted. The symbolic names for these values are: + - Function: int ferror (FILE *STREAM) + The `ferror' function returns nonzero if and only if the error + indicator for the stream STREAM is set, indicating that an error + has occurred on a previous operation on the stream. - `MM_NULLLBL' - Ignore LABEL parameter. + This symbol is declared in `stdio.h'. - `MM_NULLSEV' - Ignore SEVERITY parameter. + - Function: int ferror_unlocked (FILE *STREAM) + The `ferror_unlocked' function is equivalent to the `ferror' + function except that it does not implicitly lock the stream. - `MM_NULLMC' - Ignore CLASSIFICATION parameter. This implies that nothing is - actually printed. + This function is a GNU extension. - `MM_NULLTXT' - Ignore TEXT parameter. + This symbol is declared in `stdio.h'. - `MM_NULLACT' - Ignore ACTION parameter. + In addition to setting the error indicator associated with the +stream, the functions that operate on streams also set `errno' in the +same way as the corresponding low-level functions that operate on file +descriptors. For example, all of the functions that perform output to a +stream--such as `fputc', `printf', and `fflush'--are implemented in +terms of `write', and all of the `errno' error conditions defined for +`write' are meaningful for these functions. For more information about +the descriptor-level I/O functions, see *Note Low-Level I/O::. - `MM_NULLTAG' - Ignore TAG parameter. + +File: libc.info, Node: Error Recovery, Next: Binary Streams, Prev: EOF and Errors, Up: I/O on Streams - There is another way certain fields can be omitted from the output - to standard error. This is described below in the description of - environment variables influencing the behavior. +Recovering from errors +====================== - The SEVERITY parameter can have one of the values in the following - table: + You may explicitly clear the error and EOF flags with the `clearerr' +function. - `MM_NOSEV' - Nothing is printed, this value is the same as `MM_NULLSEV'. + - Function: void clearerr (FILE *STREAM) + This function clears the end-of-file and error indicators for the + stream STREAM. - `MM_HALT' - This value is printed as `HALT'. + The file positioning functions (*note File Positioning::) also + clear the end-of-file indicator for the stream. - `MM_ERROR' - This value is printed as `ERROR'. + - Function: void clearerr_unlocked (FILE *STREAM) + The `clearerr_unlocked' function is equivalent to the `clearerr' + function except that it does not implicitly lock the stream. - `MM_WARNING' - This value is printed as `WARNING'. + This function is a GNU extension. - `MM_INFO' - This value is printed as `INFO'. + Note that it is _not_ correct to just clear the error flag and retry +a failed stream operation. After a failed write, any number of +characters since the last buffer flush may have been committed to the +file, while some buffered data may have been discarded. Merely retrying +can thus cause lost or repeated data. - The numeric value of these five macros are between `0' and `4'. - Using the environment variable `SEV_LEVEL' or using the - `addseverity' function one can add more severity levels with their - corresponding string to print. This is described below (*note - Adding Severity Classes::). + A failed read may leave the file pointer in an inappropriate +position for a second try. In both cases, you should seek to a known +position before retrying. - If no parameter is ignored the output looks like this: + Most errors that can happen are not recoverable -- a second try will +always fail again in the same way. So usually it is best to give up and +report the error to the user, rather than install complicated recovery +logic. - LABEL: SEVERITY-STRING: TEXT - TO FIX: ACTION TAG + One important exception is `EINTR' (*note Interrupted Primitives::). +Many stream I/O implementations will treat it as an ordinary error, +which can be quite inconvenient. You can avoid this hassle by +installing all signals with the `SA_RESTART' flag. - The colons, new line characters and the `TO FIX' string are - inserted if necessary, i.e., if the corresponding parameter is not - ignored. + For similar reasons, setting nonblocking I/O on a stream's file +descriptor is not usually advisable. - This function is specified in the X/Open Portability Guide. It is - also available on all systems derived from System V. + +File: libc.info, Node: Binary Streams, Next: File Positioning, Prev: Error Recovery, Up: I/O on Streams - The function returns the value `MM_OK' if no error occurred. If - only the printing to standard error failed, it returns `MM_NOMSG'. - If printing to the console fails, it returns `MM_NOCON'. If - nothing is printed `MM_NOTOK' is returned. Among situations where - all outputs fail this last value is also returned if a parameter - value is incorrect. +Text and Binary Streams +======================= - There are two environment variables which influence the behavior of -`fmtmsg'. The first is `MSGVERB'. It is used to control the output -actually happening on standard error (_not_ the console output). Each -of the five fields can explicitly be enabled. To do this the user has -to put the `MSGVERB' variable with a format like the following in the -environment before calling the `fmtmsg' function the first time: + The GNU system and other POSIX-compatible operating systems organize +all files as uniform sequences of characters. However, some other +systems make a distinction between files containing text and files +containing binary data, and the input and output facilities of ISO C +provide for this distinction. This section tells you how to write +programs portable to such systems. - MSGVERB=KEYWORD[:KEYWORD[:...]] + When you open a stream, you can specify either a "text stream" or a +"binary stream". You indicate that you want a binary stream by +specifying the `b' modifier in the OPENTYPE argument to `fopen'; see +*Note Opening Streams::. Without this option, `fopen' opens the file +as a text stream. - Valid KEYWORDs are `label', `severity', `text', `action', and `tag'. -If the environment variable is not given or is the empty string, a not -supported keyword is given or the value is somehow else invalid, no -part of the message is masked out. + Text and binary streams differ in several ways: - The second environment variable which influences the behavior of -`fmtmsg' is `SEV_LEVEL'. This variable and the change in the behavior -of `fmtmsg' is not specified in the X/Open Portability Guide. It is -available in System V systems, though. It can be used to introduce new -severity levels. By default, only the five severity levels described -above are available. Any other numeric value would make `fmtmsg' print -nothing. + * The data read from a text stream is divided into "lines" which are + terminated by newline (`'\n'') characters, while a binary stream is + simply a long series of characters. A text stream might on some + systems fail to handle lines more than 254 characters long + (including the terminating newline character). - If the user puts `SEV_LEVEL' with a format like + * On some systems, text files can contain only printing characters, + horizontal tab characters, and newlines, and so text streams may + not support other characters. However, binary streams can handle + any character value. - SEV_LEVEL=[DESCRIPTION[:DESCRIPTION[:...]]] + * Space characters that are written immediately preceding a newline + character in a text stream may disappear when the file is read in + again. -in the environment of the process before the first call to `fmtmsg', -where DESCRIPTION has a value of the form + * More generally, there need not be a one-to-one mapping between + characters that are read from or written to a text stream, and the + characters in the actual file. - SEVERITY-KEYWORD,LEVEL,PRINTSTRING + Since a binary stream is always more capable and more predictable +than a text stream, you might wonder what purpose text streams serve. +Why not simply always use binary streams? The answer is that on these +operating systems, text and binary streams use different file formats, +and the only way to read or write "an ordinary file of text" that can +work with other text-oriented programs is through a text stream. - The SEVERITY-KEYWORD part is not used by `fmtmsg' but it has to be -present. The LEVEL part is a string representation of a number. The -numeric value must be a number greater than 4. This value must be used -in the SEVERITY parameter of `fmtmsg' to select this class. It is not -possible to overwrite any of the predefined classes. The PRINTSTRING -is the string printed when a message of this class is processed by -`fmtmsg' (see above, `fmtsmg' does not print the numeric value but -instead the string representation). + In the GNU library, and on all POSIX systems, there is no difference +between text streams and binary streams. When you open a stream, you +get the same kind of stream regardless of whether you ask for binary. +This stream can handle any file content, and has none of the +restrictions that text streams sometimes have.  -File: libc.info, Node: Adding Severity Classes, Next: Example, Prev: Printing Formatted Messages, Up: Formatted Messages +File: libc.info, Node: File Positioning, Next: Portable Positioning, Prev: Binary Streams, Up: I/O on Streams -Adding Severity Classes ------------------------ +File Positioning +================ - There is another possibility to introduce severity classes besides -using the environment variable `SEV_LEVEL'. This simplifies the task of -introducing new classes in a running program. One could use the -`setenv' or `putenv' function to set the environment variable, but this -is toilsome. + The "file position" of a stream describes where in the file the +stream is currently reading or writing. I/O on the stream advances the +file position through the file. In the GNU system, the file position is +represented as an integer, which counts the number of bytes from the +beginning of the file. *Note File Position::. - - Function: int addseverity (int SEVERITY, const char *STRING) - This function allows the introduction of new severity classes - which can be addressed by the SEVERITY parameter of the `fmtmsg' - function. The SEVERITY parameter of `addseverity' must match the - value for the parameter with the same name of `fmtmsg', and STRING - is the string printed in the actual messages instead of the numeric - value. + During I/O to an ordinary disk file, you can change the file position +whenever you wish, so as to read or write any portion of the file. Some +other kinds of files may also permit this. Files which support changing +the file position are sometimes referred to as "random-access" files. - If STRING is `NULL' the severity class with the numeric value - according to SEVERITY is removed. + You can use the functions in this section to examine or modify the +file position indicator associated with a stream. The symbols listed +below are declared in the header file `stdio.h'. - It is not possible to overwrite or remove one of the default - severity classes. All calls to `addseverity' with SEVERITY set to - one of the values for the default classes will fail. + - Function: long int ftell (FILE *STREAM) + This function returns the current file position of the stream + STREAM. - The return value is `MM_OK' if the task was successfully performed. - If the return value is `MM_NOTOK' something went wrong. This could - mean that no more memory is available or a class is not available - when it has to be removed. + This function can fail if the stream doesn't support file + positioning, or if the file position can't be represented in a + `long int', and possibly for other reasons as well. If a failure + occurs, a value of `-1' is returned. - This function is not specified in the X/Open Portability Guide - although the `fmtsmg' function is. It is available on System V - systems. + - Function: off_t ftello (FILE *STREAM) + The `ftello' function is similar to `ftell', except that it + returns a value of type `off_t'. Systems which support this type + use it to describe all file positions, unlike the POSIX + specification which uses a long int. The two are not necessarily + the same size. Therefore, using ftell can lead to problems if the + implementation is written on top of a POSIX compliant low-level + I/O implementation, and using `ftello' is preferable whenever it + is available. - -File: libc.info, Node: Example, Prev: Adding Severity Classes, Up: Formatted Messages + If this function fails it returns `(off_t) -1'. This can happen + due to missing support for file positioning or internal errors. + Otherwise the return value is the current file position. -How to use `fmtmsg' and `addseverity' -------------------------------------- + The function is an extension defined in the Unix Single + Specification version 2. - Here is a simple example program to illustrate the use of the both -functions described in this section. + When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32 bit system this function is in fact `ftello64'. I.e., the LFS + interface transparently replaces the old interface. - #include - - int - main (void) - { - addseverity (5, "NOTE2"); - fmtmsg (MM_PRINT, "only1field", MM_INFO, "text2", "action2", "tag2"); - fmtmsg (MM_PRINT, "UX:cat", 5, "invalid syntax", "refer to manual", - "UX:cat:001"); - fmtmsg (MM_PRINT, "label:foo", 6, "text", "action", "tag"); - return 0; - } + - Function: off64_t ftello64 (FILE *STREAM) + This function is similar to `ftello' with the only difference that + the return value is of type `off64_t'. This also requires that the + stream STREAM was opened using either `fopen64', `freopen64', or + `tmpfile64' since otherwise the underlying file operations to + position the file pointer beyond the 2^31 bytes limit might fail. - The second call to `fmtmsg' illustrates a use of this function as it -usually occurs on System V systems, which heavily use this function. -It seems worthwhile to give a short explanation here of how this system -works on System V. The value of the LABEL field (`UX:cat') says that -the error occurred in the Unix program `cat'. The explanation of the -error follows and the value for the ACTION parameter is `"refer to -manual"'. One could be more specific here, if necessary. The TAG -field contains, as proposed above, the value of the string given for -the LABEL parameter, and additionally a unique ID (`001' in this case). -For a GNU environment this string could contain a reference to the -corresponding node in the Info page for the program. + If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 + bits machine this function is available under the name `ftello' + and so transparently replaces the old interface. -Running this program without specifying the `MSGVERB' and `SEV_LEVEL' -function produces the following output: + - Function: int fseek (FILE *STREAM, long int OFFSET, int WHENCE) + The `fseek' function is used to change the file position of the + stream STREAM. The value of WHENCE must be one of the constants + `SEEK_SET', `SEEK_CUR', or `SEEK_END', to indicate whether the + OFFSET is relative to the beginning of the file, the current file + position, or the end of the file, respectively. - UX:cat: NOTE2: invalid syntax - TO FIX: refer to manual UX:cat:001 + This function returns a value of zero if the operation was + successful, and a nonzero value to indicate failure. A successful + call also clears the end-of-file indicator of STREAM and discards + any characters that were "pushed back" by the use of `ungetc'. - We see the different fields of the message and how the extra glue -(the colons and the `TO FIX' string) are printed. But only one of the -three calls to `fmtmsg' produced output. The first call does not print -anything because the LABEL parameter is not in the correct form. The -string must contain two fields, separated by a colon (*note Printing -Formatted Messages::). The third `fmtmsg' call produced no output -since the class with the numeric value `6' is not defined. Although a -class with numeric value `5' is also not defined by default, the call -to `addseverity' introduces it and the second call to `fmtmsg' produces -the above output. + `fseek' either flushes any buffered output before setting the file + position or else remembers it so it will be written later in its + proper place in the file. - When we change the environment of the program to contain -`SEV_LEVEL=XXX,6,NOTE' when running it we get a different result: + - Function: int fseeko (FILE *STREAM, off_t OFFSET, int WHENCE) + This function is similar to `fseek' but it corrects a problem with + `fseek' in a system with POSIX types. Using a value of type `long + int' for the offset is not compatible with POSIX. `fseeko' uses + the correct type `off_t' for the OFFSET parameter. - UX:cat: NOTE2: invalid syntax - TO FIX: refer to manual UX:cat:001 - label:foo: NOTE: text - TO FIX: action tag + For this reason it is a good idea to prefer `ftello' whenever it is + available since its functionality is (if different at all) closer + the underlying definition. - Now the third call to `fmtmsg' produced some output and we see how -the string `NOTE' from the environment variable appears in the message. + The functionality and return value is the same as for `fseek'. - Now we can reduce the output by specifying which fields we are -interested in. If we additionally set the environment variable -`MSGVERB' to the value `severity:label:action' we get the following -output: + The function is an extension defined in the Unix Single + Specification version 2. - UX:cat: NOTE2 - TO FIX: refer to manual - label:foo: NOTE - TO FIX: action + When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32 bit system this function is in fact `fseeko64'. I.e., the LFS + interface transparently replaces the old interface. -I.e., the output produced by the TEXT and the TAG parameters to -`fmtmsg' vanished. Please also note that now there is no colon after -the `NOTE' and `NOTE2' strings in the output. This is not necessary -since there is no more output on this line because the text is missing. + - Function: int fseeko64 (FILE *STREAM, off64_t OFFSET, int WHENCE) + This function is similar to `fseeko' with the only difference that + the OFFSET parameter is of type `off64_t'. This also requires + that the stream STREAM was opened using either `fopen64', + `freopen64', or `tmpfile64' since otherwise the underlying file + operations to position the file pointer beyond the 2^31 bytes + limit might fail. - -File: libc.info, Node: Low-Level I/O, Next: File System Interface, Prev: I/O on Streams, Up: Top + If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 + bits machine this function is available under the name `fseeko' + and so transparently replaces the old interface. -Low-Level Input/Output -********************** + *Portability Note:* In non-POSIX systems, `ftell', `ftello', `fseek' +and `fseeko' might work reliably only on binary streams. *Note Binary +Streams::. - This chapter describes functions for performing low-level -input/output operations on file descriptors. These functions include -the primitives for the higher-level I/O functions described in *Note -I/O on Streams::, as well as functions for performing low-level control -operations for which there are no equivalents on streams. + The following symbolic constants are defined for use as the WHENCE +argument to `fseek'. They are also used with the `lseek' function +(*note I/O Primitives::) and to specify offsets for file locks (*note +Control Operations::). - Stream-level I/O is more flexible and usually more convenient; -therefore, programmers generally use the descriptor-level functions only -when necessary. These are some of the usual reasons: + - Macro: int SEEK_SET + This is an integer constant which, when used as the WHENCE + argument to the `fseek' or `fseeko' function, specifies that the + offset provided is relative to the beginning of the file. - * For reading binary files in large chunks. + - Macro: int SEEK_CUR + This is an integer constant which, when used as the WHENCE + argument to the `fseek' or `fseeko' function, specifies that the + offset provided is relative to the current file position. - * For reading an entire file into core before parsing it. + - Macro: int SEEK_END + This is an integer constant which, when used as the WHENCE + argument to the `fseek' or `fseeko' function, specifies that the + offset provided is relative to the end of the file. - * To perform operations other than data transfer, which can only be - done with a descriptor. (You can use `fileno' to get the - descriptor corresponding to a stream.) + - Function: void rewind (FILE *STREAM) + The `rewind' function positions the stream STREAM at the beginning + of the file. It is equivalent to calling `fseek' or `fseeko' on + the STREAM with an OFFSET argument of `0L' and a WHENCE argument + of `SEEK_SET', except that the return value is discarded and the + error indicator for the stream is reset. - * To pass descriptors to a child process. (The child can create its - own stream to use a descriptor that it inherits, but cannot - inherit a stream directly.) + These three aliases for the `SEEK_...' constants exist for the sake +of compatibility with older BSD systems.

The `open' and `creat' functions are declared -in the header file `fcntl.h', while `close' is declared in `unistd.h'. +Portable File-Position Functions +================================ - - Function: int open (const char *FILENAME, int FLAGS[, mode_t MODE]) - The `open' function creates and returns a new file descriptor for - the file named by FILENAME. Initially, the file position - indicator for the file is at the beginning of the file. The - argument MODE is used only when a file is created, but it doesn't - hurt to supply the argument in any case. + On the GNU system, the file position is truly a character count. You +can specify any character count value as an argument to `fseek' or +`fseeko' and get reliable results for any random access file. However, +some ISO C systems do not represent file positions in this way. - The FLAGS argument controls how the file is to be opened. This is - a bit mask; you create the value by the bitwise OR of the - appropriate parameters (using the `|' operator in C). *Note File - Status Flags::, for the parameters available. + On some systems where text streams truly differ from binary streams, +it is impossible to represent the file position of a text stream as a +count of characters from the beginning of the file. For example, the +file position on some systems must encode both a record offset within +the file, and a character offset within the record. - The normal return value from `open' is a non-negative integer file - descriptor. In the case of an error, a value of -1 is returned - instead. In addition to the usual file name errors (*note File - Name Errors::), the following `errno' error conditions are defined - for this function: + As a consequence, if you want your programs to be portable to these +systems, you must observe certain rules: - `EACCES' - The file exists but is not readable/writable as requested by - the FLAGS argument, the file does not exist and the directory - is unwritable so it cannot be created. + * The value returned from `ftell' on a text stream has no predictable + relationship to the number of characters you have read so far. + The only thing you can rely on is that you can use it subsequently + as the OFFSET argument to `fseek' or `fseeko' to move back to the + same file position. - `EEXIST' - Both `O_CREAT' and `O_EXCL' are set, and the named file - already exists. + * In a call to `fseek' or `fseeko' on a text stream, either the + OFFSET must be zero, or WHENCE must be `SEEK_SET' and and the + OFFSET must be the result of an earlier call to `ftell' on the + same stream. - `EINTR' - The `open' operation was interrupted by a signal. *Note - Interrupted Primitives::. + * The value of the file position indicator of a text stream is + undefined while there are characters that have been pushed back + with `ungetc' that haven't been read or discarded. *Note + Unreading::. - `EISDIR' - The FLAGS argument specified write access, and the file is a - directory. + But even if you observe these rules, you may still have trouble for +long files, because `ftell' and `fseek' use a `long int' value to +represent the file position. This type may not have room to encode all +the file positions in a large file. Using the `ftello' and `fseeko' +functions might help here since the `off_t' type is expected to be able +to hold all file position values but this still does not help to handle +additional information which must be associated with a file position. - `EMFILE' - The process has too many files open. The maximum number of - file descriptors is controlled by the `RLIMIT_NOFILE' - resource limit; *note Limits on Resources::. + So if you do want to support systems with peculiar encodings for the +file positions, it is better to use the functions `fgetpos' and +`fsetpos' instead. These functions represent the file position using +the data type `fpos_t', whose internal representation varies from +system to system. - `ENFILE' - The entire system, or perhaps the file system which contains - the directory, cannot support any additional open files at - the moment. (This problem cannot happen on the GNU system.) + These symbols are declared in the header file `stdio.h'. - `ENOENT' - The named file does not exist, and `O_CREAT' is not specified. + - Data Type: fpos_t + This is the type of an object that can encode information about the + file position of a stream, for use by the functions `fgetpos' and + `fsetpos'. - `ENOSPC' - The directory or file system that would contain the new file - cannot be extended, because there is no disk space left. + In the GNU system, `fpos_t' is an opaque data structure that + contains internal data to represent file offset and conversion + state information. In other systems, it might have a different + internal representation. - `ENXIO' - `O_NONBLOCK' and `O_WRONLY' are both set in the FLAGS - argument, the file named by FILENAME is a FIFO (*note Pipes - and FIFOs::), and no process has the file open for reading. + When compiling with `_FILE_OFFSET_BITS == 64' on a 32 bit machine + this type is in fact equivalent to `fpos64_t' since the LFS + interface transparently replaces the old interface. - `EROFS' - The file resides on a read-only file system and any of - `O_WRONLY', `O_RDWR', and `O_TRUNC' are set in the FLAGS - argument, or `O_CREAT' is set and the file does not already - exist. + - Data Type: fpos64_t + This is the type of an object that can encode information about the + file position of a stream, for use by the functions `fgetpos64' and + `fsetpos64'. - If on a 32 bit machine the sources are translated with - `_FILE_OFFSET_BITS == 64' the function `open' returns a file - descriptor opened in the large file mode which enables the file - handling functions to use files up to 2^63 bytes in size and - offset from -2^63 to 2^63.

I.e., file length and file offsets can exceed 31 - bits. +Stream Buffering +================ - To use this file descriptor one must not use the normal operations - but instead the counterparts named `*64', e.g., `read64'. + Characters that are written to a stream are normally accumulated and +transmitted asynchronously to the file in a block, instead of appearing +as soon as they are output by the application program. Similarly, +streams often retrieve input from the host environment in blocks rather +than on a character-by-character basis. This is called "buffering". - When the sources are translated with `_FILE_OFFSET_BITS == 64' this - function is actually available under the name `open'. I.e., the - new, extended API using 64 bit file sizes and offsets transparently - replaces the old API. + If you are writing programs that do interactive input and output +using streams, you need to understand how buffering works when you +design the user interface to your program. Otherwise, you might find +that output (such as progress or prompt messages) doesn't appear when +you intended it to, or displays some other unexpected behavior. - - Function: int close (int FILEDES) - The function `close' closes the file descriptor FILEDES. Closing - a file has the following consequences: + This section deals only with controlling when characters are +transmitted between the stream and the file or device, and _not_ with +how things like echoing, flow control, and the like are handled on +specific classes of devices. For information on common control +operations on terminal devices, see *Note Low-Level Terminal +Interface::. - * The file descriptor is deallocated. + You can bypass the stream buffering facilities altogether by using +the low-level input and output functions that operate on file +descriptors instead. *Note Low-Level I/O::. - * Any record locks owned by the process on the file are - unlocked. +* Menu: - * When all file descriptors associated with a pipe or FIFO have - been closed, any unread data is discarded. +* Buffering Concepts:: Terminology is defined here. +* Flushing Buffers:: How to ensure that output buffers are flushed. +* Controlling Buffering:: How to specify what kind of buffering to use. - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `close' is called.

The following `errno' error - conditions are defined for this function: +Buffering Concepts +------------------ - `EBADF' - The FILEDES argument is not a valid file descriptor. + There are three different kinds of buffering strategies: - `EINTR' - The `close' call was interrupted by a signal. *Note - Interrupted Primitives::. Here is an example of how to - handle `EINTR' properly: + * Characters written to or read from an "unbuffered" stream are + transmitted individually to or from the file as soon as possible. - TEMP_FAILURE_RETRY (close (desc)); + * Characters written to a "line buffered" stream are transmitted to + the file in blocks when a newline character is encountered. - `ENOSPC' - `EIO' - `EDQUOT' - When the file is accessed by NFS, these errors from `write' - can sometimes not be detected until `close'. *Note I/O - Primitives::, for details on their meaning. + * Characters written to or read from a "fully buffered" stream are + transmitted to or from the file in blocks of arbitrary size. - Please note that there is _no_ separate `close64' function. This - is not necessary since this function does not determine nor depend - on the mode of the file. The kernel which performs the `close' - operation knows which mode the descriptor is used for and can - handle this situation. + Newly opened streams are normally fully buffered, with one +exception: a stream connected to an interactive device such as a +terminal is initially line buffered. *Note Controlling Buffering::, +for information on how to select a different kind of buffering. +Usually the automatic selection gives you the most convenient kind of +buffering for the file or device you open. - To close a stream, call `fclose' (*note Closing Streams::) instead -of trying to close its underlying file descriptor with `close'. This -flushes any buffered output and updates the stream object to indicate -that it is closed. + The use of line buffering for interactive devices implies that output +messages ending in a newline will appear immediately--which is usually +what you want. Output that doesn't end in a newline might or might not +show up immediately, so if you want them to appear immediately, you +should flush buffered output explicitly with `fflush', as described in +*Note Flushing Buffers::.  -File: libc.info, Node: I/O Primitives, Next: File Position Primitive, Prev: Opening and Closing Files, Up: Low-Level I/O +File: libc.info, Node: Flushing Buffers, Next: Controlling Buffering, Prev: Buffering Concepts, Up: Stream Buffering -Input and Output Primitives -=========================== +Flushing Buffers +---------------- - This section describes the functions for performing primitive input -and output operations on file descriptors: `read', `write', and -`lseek'. These functions are declared in the header file `unistd.h'. + "Flushing" output on a buffered stream means transmitting all +accumulated characters to the file. There are many circumstances when +buffered output on a stream is flushed automatically: - - Data Type: ssize_t - This data type is used to represent the sizes of blocks that can be - read or written in a single operation. It is similar to `size_t', - but must be a signed type. + * When you try to do output and the output buffer is full. - - Function: ssize_t read (int FILEDES, void *BUFFER, size_t SIZE) - The `read' function reads up to SIZE bytes from the file with - descriptor FILEDES, storing the results in the BUFFER. (This is - not necessarily a character string, and no terminating null - character is added.) + * When the stream is closed. *Note Closing Streams::. - The return value is the number of bytes actually read. This might - be less than SIZE; for example, if there aren't that many bytes - left in the file or if there aren't that many bytes immediately - available. The exact behavior depends on what kind of file it is. - Note that reading less than SIZE bytes is not an error. + * When the program terminates by calling `exit'. *Note Normal + Termination::. - A value of zero indicates end-of-file (except if the value of the - SIZE argument is also zero). This is not considered an error. If - you keep calling `read' while at end-of-file, it will keep - returning zero and doing nothing else. + * When a newline is written, if the stream is line buffered. - If `read' returns at least one character, there is no way you can - tell whether end-of-file was reached. But if you did reach the - end, the next read will return zero. + * Whenever an input operation on _any_ stream actually reads data + from its file. - In case of an error, `read' returns -1. The following `errno' - error conditions are defined for this function: + If you want to flush the buffered output at another time, call +`fflush', which is declared in the header file `stdio.h'. - `EAGAIN' - Normally, when no input is immediately available, `read' - waits for some input. But if the `O_NONBLOCK' flag is set - for the file (*note File Status Flags::), `read' returns - immediately without reading any data, and reports this error. + - Function: int fflush (FILE *STREAM) + This function causes any buffered output on STREAM to be delivered + to the file. If STREAM is a null pointer, then `fflush' causes + buffered output on _all_ open output streams to be flushed. - *Compatibility Note:* Most versions of BSD Unix use a - different error code for this: `EWOULDBLOCK'. In the GNU - library, `EWOULDBLOCK' is an alias for `EAGAIN', so it - doesn't matter which name you use. + This function returns `EOF' if a write error occurs, or zero + otherwise. - On some systems, reading a large amount of data from a - character special file can also fail with `EAGAIN' if the - kernel cannot find enough physical memory to lock down the - user's pages. This is limited to devices that transfer with - direct memory access into the user's memory, which means it - does not include terminals, since they always use separate - buffers inside the kernel. This problem never happens in the - GNU system. + - Function: int fflush_unlocked (FILE *STREAM) + The `fflush_unlocked' function is equivalent to the `fflush' + function except that it does not implicitly lock the stream. - Any condition that could result in `EAGAIN' can instead - result in a successful `read' which returns fewer bytes than - requested. Calling `read' again immediately would result in - `EAGAIN'. + The `fflush' function can be used to flush all streams currently +opened. While this is useful in some situations it does often more than +necessary since it might be done in situations when terminal input is +required and the program wants to be sure that all output is visible on +the terminal. But this means that only line buffered streams have to be +flushed. Solaris introduced a function especially for this. It was +always available in the GNU C library in some form but never officially +exported. - `EBADF' - The FILEDES argument is not a valid file descriptor, or is - not open for reading. + - Function: void _flushlbf (void) + The `_flushlbf' function flushes all line buffered streams + currently opened. - `EINTR' - `read' was interrupted by a signal while it was waiting for - input. *Note Interrupted Primitives::. A signal will not - necessary cause `read' to return `EINTR'; it may instead - result in a successful `read' which returns fewer bytes than - requested. + This function is declared in the `stdio_ext.h' header. - `EIO' - For many devices, and for disk files, this error code - indicates a hardware error. + *Compatibility Note:* Some brain-damaged operating systems have been +known to be so thoroughly fixated on line-oriented input and output +that flushing a line buffered stream causes a newline to be written! +Fortunately, this "feature" seems to be becoming less common. You do +not need to worry about this in the GNU system. - `EIO' also occurs when a background process tries to read - from the controlling terminal, and the normal action of - stopping the process by sending it a `SIGTTIN' signal isn't - working. This might happen if the signal is being blocked or - ignored, or because the process group is orphaned. *Note Job - Control::, for more information about job control, and *Note - Signal Handling::, for information about signals. + In some situations it might be useful to not flush the output pending +for a stream but instead simply forget it. If transmission is costly +and the output is not needed anymore this is valid reasoning. In this +situation a non-standard function introduced in Solaris and available in +the GNU C library can be used. - Please note that there is no function named `read64'. This is not - necessary since this function does not directly modify or handle - the possibly wide file offset. Since the kernel handles this state - internally, the `read' function can be used for all cases. + - Function: void __fpurge (FILE *STREAM) + The `__fpurge' function causes the buffer of the stream STREAM to + be emptied. If the stream is currently in read mode all input in + the buffer is lost. If the stream is in output mode the buffered + output is not written to the device (or whatever other underlying + storage) and the buffer the cleared. - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `read' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this, calls to - `read' should be protected using cancellation handlers. + This function is declared in `stdio_ext.h'. - The `read' function is the underlying primitive for all of the - functions that read from streams, such as `fgetc'. + +File: libc.info, Node: Controlling Buffering, Prev: Flushing Buffers, Up: Stream Buffering - - Function: ssize_t pread (int FILEDES, void *BUFFER, size_t SIZE, - off_t OFFSET) - The `pread' function is similar to the `read' function. The first - three arguments are identical, and the return values and error - codes also correspond. +Controlling Which Kind of Buffering +----------------------------------- - The difference is the fourth argument and its handling. The data - block is not read from the current position of the file descriptor - `filedes'. Instead the data is read from the file starting at - position OFFSET. The position of the file descriptor itself is - not affected by the operation. The value is the same as before - the call. + After opening a stream (but before any other operations have been +performed on it), you can explicitly specify what kind of buffering you +want it to have using the `setvbuf' function. - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `pread' function is in fact `pread64' and the type `off_t' has 64 - bits, which makes it possible to handle files up to 2^63 bytes in - length. + The facilities listed in this section are declared in the header +file `stdio.h'. - The return value of `pread' describes the number of bytes read. - In the error case it returns -1 like `read' does and the error - codes are also the same, with these additions: + - Function: int setvbuf (FILE *STREAM, char *BUF, int MODE, size_t + SIZE) + This function is used to specify that the stream STREAM should + have the buffering mode MODE, which can be either `_IOFBF' (for + full buffering), `_IOLBF' (for line buffering), or `_IONBF' (for + unbuffered input/output). - `EINVAL' - The value given for OFFSET is negative and therefore illegal. + If you specify a null pointer as the BUF argument, then `setvbuf' + allocates a buffer itself using `malloc'. This buffer will be + freed when you close the stream. - `ESPIPE' - The file descriptor FILEDES is associate with a pipe or a - FIFO and this device does not allow positioning of the file - pointer. + Otherwise, BUF should be a character array that can hold at least + SIZE characters. You should not free the space for this array as + long as the stream remains open and this array remains its buffer. + You should usually either allocate it statically, or `malloc' + (*note Unconstrained Allocation::) the buffer. Using an automatic + array is not a good idea unless you close the file before exiting + the block that declares the array. - The function is an extension defined in the Unix Single - Specification version 2. + While the array remains a stream buffer, the stream I/O functions + will use the buffer for their internal purposes. You shouldn't + try to access the values in the array directly while the stream is + using it for buffering. - - Function: ssize_t pread64 (int FILEDES, void *BUFFER, size_t SIZE, - off64_t OFFSET) - This function is similar to the `pread' function. The difference - is that the OFFSET parameter is of type `off64_t' instead of - `off_t' which makes it possible on 32 bit machines to address - files larger than 2^31 bytes and up to 2^63 bytes. The file - descriptor `filedes' must be opened using `open64' since otherwise - the large offsets possible with `off64_t' will lead to errors with - a descriptor in small file mode. + The `setvbuf' function returns zero on success, or a nonzero value + if the value of MODE is not valid or if the request could not be + honored. - When the source file is compiled with `_FILE_OFFSET_BITS == 64' on - a 32 bit machine this function is actually available under the name - `pread' and so transparently replaces the 32 bit interface. + - Macro: int _IOFBF + The value of this macro is an integer constant expression that can + be used as the MODE argument to the `setvbuf' function to specify + that the stream should be fully buffered. - - Function: ssize_t write (int FILEDES, const void *BUFFER, size_t - SIZE) - The `write' function writes up to SIZE bytes from BUFFER to the - file with descriptor FILEDES. The data in BUFFER is not - necessarily a character string and a null character is output like - any other character. + - Macro: int _IOLBF + The value of this macro is an integer constant expression that can + be used as the MODE argument to the `setvbuf' function to specify + that the stream should be line buffered. - The return value is the number of bytes actually written. This - may be SIZE, but can always be smaller. Your program should - always call `write' in a loop, iterating until all the data is - written. + - Macro: int _IONBF + The value of this macro is an integer constant expression that can + be used as the MODE argument to the `setvbuf' function to specify + that the stream should be unbuffered. - Once `write' returns, the data is enqueued to be written and can be - read back right away, but it is not necessarily written out to - permanent storage immediately. You can use `fsync' when you need - to be sure your data has been permanently stored before - continuing. (It is more efficient for the system to batch up - consecutive writes and do them all at once when convenient. - Normally they will always be written to disk within a minute or - less.) Modern systems provide another function `fdatasync' which - guarantees integrity only for the file data and is therefore - faster. You can use the `O_FSYNC' open mode to make `write' always - store the data to disk before returning; *note Operating Modes::. + - Macro: int BUFSIZ + The value of this macro is an integer constant expression that is + good to use for the SIZE argument to `setvbuf'. This value is + guaranteed to be at least `256'. - In the case of an error, `write' returns -1. The following - `errno' error conditions are defined for this function: + The value of `BUFSIZ' is chosen on each system so as to make stream + I/O efficient. So it is a good idea to use `BUFSIZ' as the size + for the buffer when you call `setvbuf'. - `EAGAIN' - Normally, `write' blocks until the write operation is - complete. But if the `O_NONBLOCK' flag is set for the file - (*note Control Operations::), it returns immediately without - writing any data and reports this error. An example of a - situation that might cause the process to block on output is - writing to a terminal device that supports flow control, - where output has been suspended by receipt of a STOP - character. + Actually, you can get an even better value to use for the buffer + size by means of the `fstat' system call: it is found in the + `st_blksize' field of the file attributes. *Note Attribute + Meanings::. - *Compatibility Note:* Most versions of BSD Unix use a - different error code for this: `EWOULDBLOCK'. In the GNU - library, `EWOULDBLOCK' is an alias for `EAGAIN', so it - doesn't matter which name you use. + Sometimes people also use `BUFSIZ' as the allocation size of + buffers used for related purposes, such as strings used to receive + a line of input with `fgets' (*note Character Input::). There is + no particular reason to use `BUFSIZ' for this instead of any other + integer, except that it might lead to doing I/O in chunks of an + efficient size. - On some systems, writing a large amount of data from a - character special file can also fail with `EAGAIN' if the - kernel cannot find enough physical memory to lock down the - user's pages. This is limited to devices that transfer with - direct memory access into the user's memory, which means it - does not include terminals, since they always use separate - buffers inside the kernel. This problem does not arise in the - GNU system. + - Function: void setbuf (FILE *STREAM, char *BUF) + If BUF is a null pointer, the effect of this function is + equivalent to calling `setvbuf' with a MODE argument of `_IONBF'. + Otherwise, it is equivalent to calling `setvbuf' with BUF, and a + MODE of `_IOFBF' and a SIZE argument of `BUFSIZ'. - `EBADF' - The FILEDES argument is not a valid file descriptor, or is - not open for writing. + The `setbuf' function is provided for compatibility with old code; + use `setvbuf' in all new programs. - `EFBIG' - The size of the file would become larger than the - implementation can support. + - Function: void setbuffer (FILE *STREAM, char *BUF, size_t SIZE) + If BUF is a null pointer, this function makes STREAM unbuffered. + Otherwise, it makes STREAM fully buffered using BUF as the buffer. + The SIZE argument specifies the length of BUF. - `EINTR' - The `write' operation was interrupted by a signal while it was - blocked waiting for completion. A signal will not - necessarily cause `write' to return `EINTR'; it may instead - result in a successful `write' which writes fewer bytes than - requested. *Note Interrupted Primitives::. + This function is provided for compatibility with old BSD code.

When this - happens, a `SIGPIPE' signal is also sent to the process; see - *Note Signal Handling::. + It is possible to query whether a given stream is line buffered or +not using a non-standard function introduced in Solaris and available +in the GNU C library. - Unless you have arranged to prevent `EINTR' failures, you should - check `errno' after each failing call to `write', and if the error - was `EINTR', you should simply repeat the call. *Note Interrupted - Primitives::. The easy way to do this is with the macro - `TEMP_FAILURE_RETRY', as follows: + - Function: int __flbf (FILE *STREAM) + The `__flbf' function will return a nonzero value in case the + stream STREAM is line buffered. Otherwise the return value is + zero. - nbytes = TEMP_FAILURE_RETRY (write (desc, buffer, count)); + This function is declared in the `stdio_ext.h' header. - Please note that there is no function named `write64'. This is not - necessary since this function does not directly modify or handle - the possibly wide file offset. Since the kernel handles this state - internally the `write' function can be used for all cases. + Two more extensions allow to determine the size of the buffer and how +much of it is used. These functions were also introduced in Solaris. - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `write' is called.

This function should not be used on buffers in read + mode or opened read-only. - The difference is the fourth argument and its handling. The data - block is not written to the current position of the file descriptor - `filedes'. Instead the data is written to the file starting at - position OFFSET. The position of the file descriptor itself is - not affected by the operation. The value is the same as before - the call. + This function is declared in the `stdio_ext.h' header. - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `pwrite' function is in fact `pwrite64' and the type `off_t' has - 64 bits, which makes it possible to handle files up to 2^63 bytes - in length. + +File: libc.info, Node: Other Kinds of Streams, Next: Formatted Messages, Prev: Stream Buffering, Up: I/O on Streams - The return value of `pwrite' describes the number of written bytes. - In the error case it returns -1 like `write' does and the error - codes are also the same, with these additions: +Other Kinds of Streams +====================== - `EINVAL' - The value given for OFFSET is negative and therefore illegal. + The GNU library provides ways for you to define additional kinds of +streams that do not necessarily correspond to an open file. - `ESPIPE' - The file descriptor FILEDES is associated with a pipe or a - FIFO and this device does not allow positioning of the file - pointer. + One such type of stream takes input from or writes output to a +string.

This specifies -the position in the file for the next `read' or `write' operation. -*Note File Positioning::, for more information on the file position and -what it means. + The `fmemopen' and `open_memstream' functions allow you to do I/O to +a string or memory buffer. These facilities are declared in `stdio.h'. - To read the current file position value from a descriptor, use -`lseek (DESC, 0, SEEK_CUR)'. + - Function: FILE * fmemopen (void *BUF, size_t SIZE, const char + *OPENTYPE) + This function opens a stream that allows the access specified by + the OPENTYPE argument, that reads from or writes to the buffer + specified by the argument BUF. This array must be at least SIZE + bytes long. - - Function: off_t lseek (int FILEDES, off_t OFFSET, int WHENCE) - The `lseek' function is used to change the file position of the - file with descriptor FILEDES. + If you specify a null pointer as the BUF argument, `fmemopen' + dynamically allocates an array SIZE bytes long (as with `malloc'; + *note Unconstrained Allocation::). This is really only useful if + you are going to write things to the buffer and then read them back + in again, because you have no way of actually getting a pointer to + the buffer (for this, try `open_memstream', below). The buffer is + freed when the stream is closed. - The WHENCE argument specifies how the OFFSET should be - interpreted, in the same way as for the `fseek' function, and it - must be one of the symbolic constants `SEEK_SET', `SEEK_CUR', or - `SEEK_END'. + The argument OPENTYPE is the same as in `fopen' (*note Opening + Streams::). If the OPENTYPE specifies append mode, then the + initial file position is set to the first null character in the + buffer. Otherwise the initial file position is at the beginning + of the buffer. - `SEEK_SET' - Specifies that WHENCE is a count of characters from the - beginning of the file. + When a stream open for writing is flushed or closed, a null + character (zero byte) is written at the end of the buffer if it + fits. You should add an extra byte to the SIZE argument to + account for this. Attempts to write more than SIZE bytes to the + buffer result in an error. - `SEEK_CUR' - Specifies that WHENCE is a count of characters from the - current file position. This count may be positive or - negative. + For a stream open for reading, null characters (zero bytes) in the + buffer do not count as "end of file". Read operations indicate + end of file only when the file position advances past SIZE bytes. + So, if you want to read characters from a null-terminated string, + you should supply the length of the string as the SIZE argument. - `SEEK_END' - Specifies that WHENCE is a count of characters from the end of - the file. A negative count specifies a position within the - current extent of the file; a positive count specifies a - position past the current end. If you set the position past - the current end, and actually write data, you will extend the - file with zeros up to that position. + Here is an example of using `fmemopen' to create a stream for +reading from a string: - The return value from `lseek' is normally the resulting file - position, measured in bytes from the beginning of the file.

Another - process may write more data after you seek but before you write, - extending the file so the position you write onto clobbers their - data. Instead, use the `O_APPEND' operating mode; *note Operating - Modes::. + This program produces the following output: - You can set the file position past the current end of the file. - This does not by itself make the file longer; `lseek' never - changes the file. But subsequent output at that position will - extend the file. Characters between the previous end of file and - the new position are filled with zeros. Extending the file in - this way can create a "hole": the blocks of zeros are not actually - allocated on disk, so the file takes up less space than it appears - to; it is then called a "sparse file". + Got f + Got o + Got o + Got b + Got a + Got r - If the file position cannot be changed, or the operation is in - some way invalid, `lseek' returns a value of -1. The following - `errno' error conditions are defined for this function: + - Function: FILE * open_memstream (char **PTR, size_t *SIZELOC) + This function opens a stream for writing to a buffer.

To +select the destination the programmer can use the following two values, +bitwise OR combined if wanted, for the CLASSIFICATION parameter of +`fmtmsg': - If you have been using a stream for I/O, and you want to do I/O using -another channel (either a stream or a descriptor) that is linked to it, -you must first "clean up" the stream that you have been using. *Note -Cleaning Streams::. +`MM_PRINT' + Display the message in standard error. - Terminating a process, or executing a new program in the process, -destroys all the streams in the process.

These are called -"independent channels". +`MM_SOFT' + The source of the condition is some software. - The system handles each channel independently. Most of the time, -this is quite predictable and natural (especially for input): each -channel can read or write sequentially at its own place in the file. -However, if some of the channels are streams, you must take these -precautions: +`MM_FIRM' + The source of the condition is some firmware. - * You should clean an output stream after use, before doing anything - else that might read or write from the same part of the file. + A third component of the CLASSIFICATION parameter to `fmtmsg' can +describe the part of the system which detects the problem. This is +done by using exactly one of the following values: - * You should clean an input stream before reading data that may have - been modified using an independent channel. Otherwise, you might - read obsolete data that had been in the stream's buffer. +`MM_APPL' + The erroneous condition is detected by the application. - If you do output to one channel at the end of the file, this will -certainly leave the other independent channels positioned somewhere -before the new end. You cannot reliably set their file positions to the -new end of file before writing, because the file can always be extended -by another process between when you set the file position and when you -write the data. Instead, use an append-type descriptor or stream; they -always output at the current end of the file. In order to make the -end-of-file position accurate, you must clean the output channel you -were using, if it is a stream. +`MM_UTIL' + The erroneous condition is detected by a utility. - It's impossible for two channels to have separate file pointers for a -file that doesn't support random access. Thus, channels for reading or -writing such files are always linked, never independent. Append-type -channels are also always linked. For these channels, follow the rules -for linked channels; see *Note Linked Channels::. +`MM_OPSYS' + The erroneous condition is detected by the operating system. - -File: libc.info, Node: Cleaning Streams, Prev: Independent Channels, Up: Stream/Descriptor Precautions + A last component of CLASSIFICATION can signal the results of this +message. Exactly one of the following values can be used: -Cleaning Streams ----------------- +`MM_RECOVER' + It is a recoverable error. - On the GNU system, you can clean up any stream with `fclean': +`MM_NRECOV' + It is a non-recoverable error. - - Function: int fclean (FILE *STREAM) - Clean up the stream STREAM so that its buffer is empty.

The TEXT + parameter describes the condition of the error, the ACTION + parameter possible steps to recover from the error and the TAG + parameter is a reference to the online documentation where more + information can be found. It should contain the LABEL value and a + unique identification number. - On other systems, you can use `fflush' to clean a stream in most -cases. + Each of the parameters can be a special value which means this + value is to be omitted. The symbolic names for these values are: - You can skip the `fclean' or `fflush' if you know the stream is -already clean. A stream is clean whenever its buffer is empty. For -example, an unbuffered stream is always clean. An input stream that is -at end-of-file is clean.

This is when the stream is doing input from a file that is not -random-access. Such streams typically read ahead, and when the file is -not random access, there is no way to give back the excess data already -read. When an input stream reads from a random-access file, `fflush' -does clean the stream, but leaves the file pointer at an unpredictable -place; you must set the file pointer before doing any further I/O. On -the GNU system, using `fclean' avoids both of these problems. + `MM_NULLSEV' + Ignore SEVERITY parameter. - Closing an output-only stream also does `fflush', so this is a valid -way of cleaning an output stream. On the GNU system, closing an input -stream does `fclean'. + `MM_NULLMC' + Ignore CLASSIFICATION parameter. This implies that nothing is + actually printed. - You need not clean a stream before using its descriptor for control -operations such as setting terminal modes; these operations don't affect -the file position and are not affected by it.

This is described below in the description of + environment variables influencing the behavior. + + The SEVERITY parameter can have one of the values in the following + table: + + `MM_NOSEV' + Nothing is printed, this value is the same as `MM_NULLSEV'. + + `MM_HALT' + This value is printed as `HALT'. + + `MM_ERROR' + This value is printed as `ERROR'. + + `MM_WARNING' + This value is printed as `WARNING'. + + `MM_INFO' + This value is printed as `INFO'. + + The numeric value of these five macros are between `0' and `4'. + Using the environment variable `SEV_LEVEL' or using the + `addseverity' function one can add more severity levels with their + corresponding string to print. This is described below (*note + Adding Severity Classes::). + + If no parameter is ignored the output looks like this: + + LABEL: SEVERITY-STRING: TEXT + TO FIX: ACTION TAG + + The colons, new line characters and the `TO FIX' string are + inserted if necessary, i.e., if the corresponding parameter is not + ignored. + + This function is specified in the X/Open Portability Guide. It is + also available on all systems derived from System V. + + The function returns the value `MM_OK' if no error occurred. If + only the printing to standard error failed, it returns `MM_NOMSG'. + If printing to the console fails, it returns `MM_NOCON'. If + nothing is printed `MM_NOTOK' is returned. Among situations where + all outputs fail this last value is also returned if a parameter + value is incorrect. + + There are two environment variables which influence the behavior of +`fmtmsg'. The first is `MSGVERB'. It is used to control the output +actually happening on standard error (_not_ the console output). Each +of the five fields can explicitly be enabled. To do this the user has +to put the `MSGVERB' variable with a format like the following in the +environment before calling the `fmtmsg' function the first time: + + MSGVERB=KEYWORD[:KEYWORD[:...]] + + Valid KEYWORDs are `label', `severity', `text', `action', and `tag'. +If the environment variable is not given or is the empty string, a not +supported keyword is given or the value is somehow else invalid, no +part of the message is masked out. + + The second environment variable which influences the behavior of +`fmtmsg' is `SEV_LEVEL'. This variable and the change in the behavior +of `fmtmsg' is not specified in the X/Open Portability Guide. It is +available in System V systems, though. It can be used to introduce new +severity levels. By default, only the five severity levels described +above are available. Any other numeric value would make `fmtmsg' print +nothing. + + If the user puts `SEV_LEVEL' with a format like + + SEV_LEVEL=[DESCRIPTION[:DESCRIPTION[:...]]] + +in the environment of the process before the first call to `fmtmsg', +where DESCRIPTION has a value of the form + + SEVERITY-KEYWORD,LEVEL,PRINTSTRING + + The SEVERITY-KEYWORD part is not used by `fmtmsg' but it has to be +present. The LEVEL part is a string representation of a number. The +numeric value must be a number greater than 4. This value must be used +in the SEVERITY parameter of `fmtmsg' to select this class. It is not +possible to overwrite any of the predefined classes. The PRINTSTRING +is the string printed when a message of this class is processed by +`fmtmsg' (see above, `fmtsmg' does not print the numeric value but +instead the string representation).  -File: libc.info, Node: Scatter-Gather, Next: Memory-mapped I/O, Prev: Stream/Descriptor Precautions, Up: Low-Level I/O +File: libc.info, Node: Adding Severity Classes, Next: Example, Prev: Printing Formatted Messages, Up: Formatted Messages -Fast Scatter-Gather I/O -======================= +Adding Severity Classes +----------------------- - Some applications may need to read or write data to multiple buffers, -which are separated in memory. Although this can be done easily enough -with multiple calls to `read' and `write', it is inefficient because -there is overhead associated with each kernel call. + There is another possibility to introduce severity classes besides +using the environment variable `SEV_LEVEL'. This simplifies the task of +introducing new classes in a running program. One could use the +`setenv' or `putenv' function to set the environment variable, but this +is toilsome. - Instead, many platforms provide special high-speed primitives to -perform these "scatter-gather" operations in a single kernel call. The -GNU C library will provide an emulation on any system that lacks these -primitives, so they are not a portability threat. They are defined in -`sys/uio.h'. + - Function: int addseverity (int SEVERITY, const char *STRING) + This function allows the introduction of new severity classes + which can be addressed by the SEVERITY parameter of the `fmtmsg' + function. The SEVERITY parameter of `addseverity' must match the + value for the parameter with the same name of `fmtmsg', and STRING + is the string printed in the actual messages instead of the numeric + value. - These functions are controlled with arrays of `iovec' structures, -which describe the location and size of each buffer. + If STRING is `NULL' the severity class with the numeric value + according to SEVERITY is removed. - - Data Type: struct iovec - The `iovec' structure describes a buffer. It contains two fields: + It is not possible to overwrite or remove one of the default + severity classes. All calls to `addseverity' with SEVERITY set to + one of the values for the default classes will fail. - `void *iov_base' - Contains the address of a buffer. + The return value is `MM_OK' if the task was successfully performed. + If the return value is `MM_NOTOK' something went wrong. This could + mean that no more memory is available or a class is not available + when it has to be removed. - `size_t iov_len' - Contains the length of the buffer. + This function is not specified in the X/Open Portability Guide + although the `fmtsmg' function is. It is available on System V + systems. + +File: libc.info, Node: Example, Prev: Adding Severity Classes, Up: Formatted Messages - - Function: ssize_t readv (int FILEDES, const struct iovec *VECTOR, - int COUNT) - The `readv' function reads data from FILEDES and scatters it into - the buffers described in VECTOR, which is taken to be COUNT - structures long. As each buffer is filled, data is sent to the - next. +How to use `fmtmsg' and `addseverity' +------------------------------------- - Note that `readv' is not guaranteed to fill all the buffers. It - may stop at any point, for the same reasons `read' would. + Here is a simple example program to illustrate the use of the both +functions described in this section. - The return value is a count of bytes (_not_ buffers) read, 0 - indicating end-of-file, or -1 indicating an error. The possible - errors are the same as in `read'. + #include + + int + main (void) + { + addseverity (5, "NOTE2"); + fmtmsg (MM_PRINT, "only1field", MM_INFO, "text2", "action2", "tag2"); + fmtmsg (MM_PRINT, "UX:cat", 5, "invalid syntax", "refer to manual", + "UX:cat:001"); + fmtmsg (MM_PRINT, "label:foo", 6, "text", "action", "tag"); + return 0; + } + The second call to `fmtmsg' illustrates a use of this function as it +usually occurs on System V systems, which heavily use this function. +It seems worthwhile to give a short explanation here of how this system +works on System V. The value of the LABEL field (`UX:cat') says that +the error occurred in the Unix program `cat'. The explanation of the +error follows and the value for the ACTION parameter is `"refer to +manual"'. One could be more specific here, if necessary. The TAG +field contains, as proposed above, the value of the string given for +the LABEL parameter, and additionally a unique ID (`001' in this case). +For a GNU environment this string could contain a reference to the +corresponding node in the Info page for the program. - - Function: ssize_t writev (int FILEDES, const struct iovec *VECTOR, - int COUNT) - The `writev' function gathers data from the buffers described in - VECTOR, which is taken to be COUNT structures long, and writes - them to `filedes'. As each buffer is written, it moves on to the - next. +Running this program without specifying the `MSGVERB' and `SEV_LEVEL' +function produces the following output: - Like `readv', `writev' may stop midstream under the same - conditions `write' would. + UX:cat: NOTE2: invalid syntax + TO FIX: refer to manual UX:cat:001 - The return value is a count of bytes written, or -1 indicating an - error. The possible errors are the same as in `write'. + We see the different fields of the message and how the extra glue +(the colons and the `TO FIX' string) are printed. But only one of the +three calls to `fmtmsg' produced output. The first call does not print +anything because the LABEL parameter is not in the correct form. The +string must contain two fields, separated by a colon (*note Printing +Formatted Messages::). The third `fmtmsg' call produced no output +since the class with the numeric value `6' is not defined. Although a +class with numeric value `5' is also not defined by default, the call +to `addseverity' introduces it and the second call to `fmtmsg' produces +the above output. + When we change the environment of the program to contain +`SEV_LEVEL=XXX,6,NOTE' when running it we get a different result: - Note that if the buffers are small (under about 1kB), high-level -streams may be easier to use than these functions. However, `readv' and -`writev' are more efficient when the individual buffers themselves (as -opposed to the total output), are large. In that case, a high-level -stream would not be able to cache the data effectively. + UX:cat: NOTE2: invalid syntax + TO FIX: refer to manual UX:cat:001 + label:foo: NOTE: text + TO FIX: action tag + + Now the third call to `fmtmsg' produced some output and we see how +the string `NOTE' from the environment variable appears in the message. + + Now we can reduce the output by specifying which fields we are +interested in. If we additionally set the environment variable +`MSGVERB' to the value `severity:label:action' we get the following +output: + + UX:cat: NOTE2 + TO FIX: refer to manual + label:foo: NOTE + TO FIX: action + +I.e., the output produced by the TEXT and the TAG parameters to +`fmtmsg' vanished. Please also note that now there is no colon after +the `NOTE' and `NOTE2' strings in the output. This is not necessary +since there is no more output on this line because the text is missing. + + +File: libc.info, Node: Low-Level I/O, Next: File System Interface, Prev: I/O on Streams, Up: Top + +Low-Level Input/Output +********************** + + This chapter describes functions for performing low-level +input/output operations on file descriptors.

When the sources are translated with `_FILE_OFFSET_BITS == 64' this - function is actually available under the name `mmap'. I.e., the + function is actually available under the name `open'. I.e., the new, extended API using 64 bit file sizes and offsets transparently replaces the old API. - - Function: int munmap (void *ADDR, size_t LENGTH) - `munmap' removes any memory maps from (ADDR) to (ADDR + LENGTH). - LENGTH should be the length of the mapping. - - It is safe to unmap multiple mappings in one command, or include - unmapped space in the range. It is also possible to unmap only - part of an existing mapping. However, only entire pages can be - removed. If LENGTH is not an even number of pages, it will be - rounded up. - - It returns 0 for success and -1 for an error. + - Function: int close (int FILEDES) + The function `close' closes the file descriptor FILEDES. Closing + a file has the following consequences: - One error is possible: + * The file descriptor is deallocated. - `EINVAL' - The memory range given was outside the user mmap range or - wasn't page aligned. + * Any record locks owned by the process on the file are + unlocked. + * When all file descriptors associated with a pipe or FIFO have + been closed, any unread data is discarded. - - Function: int msync (void *ADDRESS, size_t LENGTH, int FLAGS) - When using shared mappings, the kernel can write the file at any - time before the mapping is removed. To be certain data has - actually been written to the file and will be accessible to - non-memory-mapped I/O, it is necessary to use this function. + This function is a cancellation point in multi-threaded programs. + This is a problem if the thread allocates some resources (like + memory, file descriptors, semaphores or whatever) at the time + `close' is called. If the thread gets canceled these resources + stay allocated until the program ends. To avoid this, calls to + `close' should be protected using cancellation handlers. - It operates on the region ADDRESS to (ADDRESS + LENGTH). It may - be used on part of a mapping or multiple mappings, however the - region given should not contain any unmapped space. + The normal return value from `close' is 0; a value of -1 is + returned in case of failure. The following `errno' error + conditions are defined for this function: - FLAGS can contain some options: + `EBADF' + The FILEDES argument is not a valid file descriptor. - `MS_SYNC' - This flag makes sure the data is actually written _to disk_. - Normally `msync' only makes sure that accesses to a file with - conventional I/O reflect the recent changes. + `EINTR' + The `close' call was interrupted by a signal. *Note + Interrupted Primitives::. Here is an example of how to + handle `EINTR' properly: - `MS_ASYNC' - This tells `msync' to begin the synchronization, but not to - wait for it to complete. + TEMP_FAILURE_RETRY (close (desc)); - `msync' returns 0 for success and -1 for error. Errors include: + `ENOSPC' + `EIO' + `EDQUOT' + When the file is accessed by NFS, these errors from `write' + can sometimes not be detected until `close'. *Note I/O + Primitives::, for details on their meaning. - `EINVAL' - An invalid region was given, or the FLAGS were invalid. + Please note that there is _no_ separate `close64' function. This + is not necessary since this function does not determine nor depend + on the mode of the file. The kernel which performs the `close' + operation knows which mode the descriptor is used for and can + handle this situation. - `EFAULT' - There is no existing mapping in at least part of the given - region. + To close a stream, call `fclose' (*note Closing Streams::) instead +of trying to close its underlying file descriptor with `close'. This +flushes any buffered output and updates the stream object to indicate +that it is closed. + +File: libc.info, Node: I/O Primitives, Next: File Position Primitive, Prev: Opening and Closing Files, Up: Low-Level I/O - - Function: void * mremap (void *ADDRESS, size_t LENGTH, size_t - NEW_LENGTH, int FLAG) - This function can be used to change the size of an existing memory - area. ADDRESS and LENGTH must cover a region entirely mapped in - the same `mmap' statement. A new mapping with the same - characteristics will be returned with the length NEW_LENGTH. +Input and Output Primitives +=========================== - One option is possible, `MREMAP_MAYMOVE'. If it is given in FLAGS, - the system may remove the existing mapping and create a new one of - the desired length in another location. + This section describes the functions for performing primitive input +and output operations on file descriptors: `read', `write', and +`lseek'. These functions are declared in the header file `unistd.h'. - The address of the resulting mapping is returned, or -1. Possible - error codes include: + - Data Type: ssize_t + This data type is used to represent the sizes of blocks that can be + read or written in a single operation. It is similar to `size_t', + but must be a signed type. - `EFAULT' - There is no existing mapping in at least part of the original - region, or the region covers two or more distinct mappings. + - Function: ssize_t read (int FILEDES, void *BUFFER, size_t SIZE) + The `read' function reads up to SIZE bytes from the file with + descriptor FILEDES, storing the results in the BUFFER. (This is + not necessarily a character string, and no terminating null + character is added.) - `EINVAL' - The address given is misaligned or inappropriate. + The return value is the number of bytes actually read. This might + be less than SIZE; for example, if there aren't that many bytes + left in the file or if there aren't that many bytes immediately + available. The exact behavior depends on what kind of file it is. + Note that reading less than SIZE bytes is not an error. - `EAGAIN' - The region has pages locked, and if extended it would exceed - the process's resource limit for locked pages. *Note Limits - on Resources::. + A value of zero indicates end-of-file (except if the value of the + SIZE argument is also zero). This is not considered an error. If + you keep calling `read' while at end-of-file, it will keep + returning zero and doing nothing else. - `ENOMEM' - The region is private writable, and insufficient virtual - memory is available to extend it. Also, this error will - occur if `MREMAP_MAYMOVE' is not given and the extension - would collide with another mapped region. + If `read' returns at least one character, there is no way you can + tell whether end-of-file was reached. But if you did reach the + end, the next read will return zero. + In case of an error, `read' returns -1. The following `errno' + error conditions are defined for this function: - This function is only available on a few systems. Except for -performing optional optimizations one should not rely on this function. + `EAGAIN' + Normally, when no input is immediately available, `read' + waits for some input. But if the `O_NONBLOCK' flag is set + for the file (*note File Status Flags::), `read' returns + immediately without reading any data, and reports this error. - Not all file descriptors may be mapped. Sockets, pipes, and most -devices only allow sequential access and do not fit into the mapping -abstraction. In addition, some regular files may not be mmapable, and -older kernels may not support mapping at all. Thus, programs using -`mmap' should have a fallback method to use should it fail. *Note Mmap: -(standards)Mmap. + *Compatibility Note:* Most versions of BSD Unix use a + different error code for this: `EWOULDBLOCK'. In the GNU + library, `EWOULDBLOCK' is an alias for `EAGAIN', so it + doesn't matter which name you use. - - Function: int madvise (void *ADDR, size_t LENGTH, int ADVICE) - This function can be used to provide the system with ADVICE about - the intended usage patterns of the memory region starting at ADDR - and extending LENGTH bytes. + On some systems, reading a large amount of data from a + character special file can also fail with `EAGAIN' if the + kernel cannot find enough physical memory to lock down the + user's pages. This is limited to devices that transfer with + direct memory access into the user's memory, which means it + does not include terminals, since they always use separate + buffers inside the kernel. This problem never happens in the + GNU system. - The valid BSD values for ADVICE are: + Any condition that could result in `EAGAIN' can instead + result in a successful `read' which returns fewer bytes than + requested. Calling `read' again immediately would result in + `EAGAIN'. - `MADV_NORMAL' - The region should receive no further special treatment. + `EBADF' + The FILEDES argument is not a valid file descriptor, or is + not open for reading. - `MADV_RANDOM' - The region will be accessed via random page references. The - kernel should page-in the minimal number of pages for each - page fault. + `EINTR' + `read' was interrupted by a signal while it was waiting for + input. *Note Interrupted Primitives::. A signal will not + necessary cause `read' to return `EINTR'; it may instead + result in a successful `read' which returns fewer bytes than + requested. - `MADV_SEQUENTIAL' - The region will be accessed via sequential page references. - This may cause the kernel to aggressively read-ahead, - expecting further sequential references after any page fault - within this region. + `EIO' + For many devices, and for disk files, this error code + indicates a hardware error. - `MADV_WILLNEED' - The region will be needed. The pages within this region may - be pre-faulted in by the kernel. + `EIO' also occurs when a background process tries to read + from the controlling terminal, and the normal action of + stopping the process by sending it a `SIGTTIN' signal isn't + working. This might happen if the signal is being blocked or + ignored, or because the process group is orphaned. *Note Job + Control::, for more information about job control, and *Note + Signal Handling::, for information about signals. - `MADV_DONTNEED' - The region is no longer needed. The kernel may free these - pages, causing any changes to the pages to be lost, as well - as swapped out pages to be discarded. + Please note that there is no function named `read64'. This is not + necessary since this function does not directly modify or handle + the possibly wide file offset. Since the kernel handles this state + internally, the `read' function can be used for all cases. - The POSIX names are slightly different, but with the same meanings: + This function is a cancellation point in multi-threaded programs. + This is a problem if the thread allocates some resources (like + memory, file descriptors, semaphores or whatever) at the time + `read' is called. If the thread gets canceled these resources + stay allocated until the program ends. To avoid this, calls to + `read' should be protected using cancellation handlers. - `POSIX_MADV_NORMAL' - This corresponds with BSD's `MADV_NORMAL'. + The `read' function is the underlying primitive for all of the + functions that read from streams, such as `fgetc'. - `POSIX_MADV_RANDOM' - This corresponds with BSD's `MADV_RANDOM'. + - Function: ssize_t pread (int FILEDES, void *BUFFER, size_t SIZE, + off_t OFFSET) + The `pread' function is similar to the `read' function. The first + three arguments are identical, and the return values and error + codes also correspond. - `POSIX_MADV_SEQUENTIAL' - This corresponds with BSD's `MADV_SEQUENTIAL'. + The difference is the fourth argument and its handling. The data + block is not read from the current position of the file descriptor + `filedes'. Instead the data is read from the file starting at + position OFFSET. The position of the file descriptor itself is + not affected by the operation. The value is the same as before + the call. - `POSIX_MADV_WILLNEED' - This corresponds with BSD's `MADV_WILLNEED'. + When the source file is compiled with `_FILE_OFFSET_BITS == 64' the + `pread' function is in fact `pread64' and the type `off_t' has 64 + bits, which makes it possible to handle files up to 2^63 bytes in + length. - `POSIX_MADV_DONTNEED' - This corresponds with BSD's `MADV_DONTNEED'. + The return value of `pread' describes the number of bytes read. + In the error case it returns -1 like `read' does and the error + codes are also the same, with these additions: - `msync' returns 0 for success and -1 for error. Errors include: `EINVAL' - An invalid region was given, or the ADVICE was invalid. - - `EFAULT' - There is no existing mapping in at least part of the given - region. - + The value given for OFFSET is negative and therefore illegal. - -File: libc.info, Node: Waiting for I/O, Next: Synchronizing I/O, Prev: Memory-mapped I/O, Up: Low-Level I/O + `ESPIPE' + The file descriptor FILEDES is associate with a pipe or a + FIFO and this device does not allow positioning of the file + pointer. -Waiting for Input or Output -=========================== + The function is an extension defined in the Unix Single + Specification version 2. - Sometimes a program needs to accept input on multiple input channels -whenever input arrives. For example, some workstations may have devices -such as a digitizing tablet, function button box, or dial box that are -connected via normal asynchronous serial interfaces; good user interface -style requires responding immediately to input on any device. Another -example is a program that acts as a server to several other processes -via pipes or sockets. + - Function: ssize_t pread64 (int FILEDES, void *BUFFER, size_t SIZE, + off64_t OFFSET) + This function is similar to the `pread' function. The difference + is that the OFFSET parameter is of type `off64_t' instead of + `off_t' which makes it possible on 32 bit machines to address + files larger than 2^31 bytes and up to 2^63 bytes. The file + descriptor `filedes' must be opened using `open64' since otherwise + the large offsets possible with `off64_t' will lead to errors with + a descriptor in small file mode. - You cannot normally use `read' for this purpose, because this blocks -the program until input is available on one particular file descriptor; -input on other channels won't wake it up. You could set nonblocking -mode and poll each file descriptor in turn, but this is very -inefficient. + When the source file is compiled with `_FILE_OFFSET_BITS == 64' on + a 32 bit machine this function is actually available under the name + `pread' and so transparently replaces the 32 bit interface. - A better solution is to use the `select' function. This blocks the -program until input or output is ready on a specified set of file -descriptors, or until a timer expires, whichever comes first. This -facility is declared in the header file `sys/types.h'. + - Function: ssize_t write (int FILEDES, const void *BUFFER, size_t + SIZE) + The `write' function writes up to SIZE bytes from BUFFER to the + file with descriptor FILEDES. The data in BUFFER is not + necessarily a character string and a null character is output like + any other character. - In the case of a server socket (*note Listening::), we say that -"input" is available when there are pending connections that could be -accepted (*note Accepting Connections::). `accept' for server sockets -blocks and interacts with `select' just as `read' does for normal input. + The return value is the number of bytes actually written. This + may be SIZE, but can always be smaller. Your program should + always call `write' in a loop, iterating until all the data is + written. - The file descriptor sets for the `select' function are specified as -`fd_set' objects. Here is the description of the data type and some -macros for manipulating these objects. + Once `write' returns, the data is enqueued to be written and can be + read back right away, but it is not necessarily written out to + permanent storage immediately. You can use `fsync' when you need + to be sure your data has been permanently stored before + continuing. (It is more efficient for the system to batch up + consecutive writes and do them all at once when convenient. + Normally they will always be written to disk within a minute or + less.) Modern systems provide another function `fdatasync' which + guarantees integrity only for the file data and is therefore + faster. You can use the `O_FSYNC' open mode to make `write' always + store the data to disk before returning; *note Operating Modes::. - - Data Type: fd_set - The `fd_set' data type represents file descriptor sets for the - `select' function. It is actually a bit array. + In the case of an error, `write' returns -1. The following + `errno' error conditions are defined for this function: - - Macro: int FD_SETSIZE - The value of this macro is the maximum number of file descriptors - that a `fd_set' object can hold information about. On systems - with a fixed maximum number, `FD_SETSIZE' is at least that number. - On some systems, including GNU, there is no absolute limit on the - number of descriptors open, but this macro still has a constant - value which controls the number of bits in an `fd_set'; if you get - a file descriptor with a value as high as `FD_SETSIZE', you cannot - put that descriptor into an `fd_set'. + `EAGAIN' + Normally, `write' blocks until the write operation is + complete. But if the `O_NONBLOCK' flag is set for the file + (*note Control Operations::), it returns immediately without + writing any data and reports this error. An example of a + situation that might cause the process to block on output is + writing to a terminal device that supports flow control, + where output has been suspended by receipt of a STOP + character. - - Macro: void FD_ZERO (fd_set *SET) - This macro initializes the file descriptor set SET to be the empty - set. + *Compatibility Note:* Most versions of BSD Unix use a + different error code for this: `EWOULDBLOCK'. In the GNU + library, `EWOULDBLOCK' is an alias for `EAGAIN', so it + doesn't matter which name you use. - - Macro: void FD_SET (int FILEDES, fd_set *SET) - This macro adds FILEDES to the file descriptor set SET. + On some systems, writing a large amount of data from a + character special file can also fail with `EAGAIN' if the + kernel cannot find enough physical memory to lock down the + user's pages. This is limited to devices that transfer with + direct memory access into the user's memory, which means it + does not include terminals, since they always use separate + buffers inside the kernel. This problem does not arise in the + GNU system. - - Macro: void FD_CLR (int FILEDES, fd_set *SET) - This macro removes FILEDES from the file descriptor set SET. + `EBADF' + The FILEDES argument is not a valid file descriptor, or is + not open for writing. - - Macro: int FD_ISSET (int FILEDES, fd_set *SET) - This macro returns a nonzero value (true) if FILEDES is a member - of the file descriptor set SET, and zero (false) otherwise. + `EFBIG' + The size of the file would become larger than the + implementation can support. - Next, here is the description of the `select' function itself. + `EINTR' + The `write' operation was interrupted by a signal while it was + blocked waiting for completion. A signal will not + necessarily cause `write' to return `EINTR'; it may instead + result in a successful `write' which writes fewer bytes than + requested. *Note Interrupted Primitives::. - - Function: int select (int NFDS, fd_set *READ-FDS, fd_set *WRITE-FDS, - fd_set *EXCEPT-FDS, struct timeval *TIMEOUT) - The `select' function blocks the calling process until there is - activity on any of the specified sets of file descriptors, or - until the timeout period has expired. + `EIO' + For many devices, and for disk files, this error code + indicates a hardware error. - The file descriptors specified by the READ-FDS argument are - checked to see if they are ready for reading; the WRITE-FDS file - descriptors are checked to see if they are ready for writing; and - the EXCEPT-FDS file descriptors are checked for exceptional - conditions. You can pass a null pointer for any of these - arguments if you are not interested in checking for that kind of - condition. + `ENOSPC' + The device containing the file is full. - A file descriptor is considered ready for reading if it is not at - end of file. A server socket is considered ready for reading if - there is a pending connection which can be accepted with `accept'; - *note Accepting Connections::. A client socket is ready for - writing when its connection is fully established; *note - Connecting::. + `EPIPE' + This error is returned when you try to write to a pipe or + FIFO that isn't open for reading by any process. When this + happens, a `SIGPIPE' signal is also sent to the process; see + *Note Signal Handling::. - "Exceptional conditions" does not mean errors--errors are reported - immediately when an erroneous system call is executed, and do not - constitute a state of the descriptor. Rather, they include - conditions such as the presence of an urgent message on a socket. - (*Note Sockets::, for information on urgent messages.) + Unless you have arranged to prevent `EINTR' failures, you should + check `errno' after each failing call to `write', and if the error + was `EINTR', you should simply repeat the call. *Note Interrupted + Primitives::. The easy way to do this is with the macro + `TEMP_FAILURE_RETRY', as follows: - The `select' function checks only the first NFDS file descriptors. - The usual thing is to pass `FD_SETSIZE' as the value of this - argument. + nbytes = TEMP_FAILURE_RETRY (write (desc, buffer, count)); - The TIMEOUT specifies the maximum time to wait. If you pass a - null pointer for this argument, it means to block indefinitely - until one of the file descriptors is ready. Otherwise, you should - provide the time in `struct timeval' format; see *Note - High-Resolution Calendar::. Specify zero as the time (a `struct - timeval' containing all zeros) if you want to find out which - descriptors are ready without waiting if none are ready. + Please note that there is no function named `write64'. This is not + necessary since this function does not directly modify or handle + the possibly wide file offset. Since the kernel handles this state + internally the `write' function can be used for all cases. - The normal return value from `select' is the total number of ready - file descriptors in all of the sets. Each of the argument sets is - overwritten with information about the descriptors that are ready - for the corresponding operation. Thus, to see if a particular - descriptor DESC has input, use `FD_ISSET (DESC, READ-FDS)' after - `select' returns. + This function is a cancellation point in multi-threaded programs. + This is a problem if the thread allocates some resources (like + memory, file descriptors, semaphores or whatever) at the time + `write' is called. If the thread gets canceled these resources + stay allocated until the program ends. To avoid this, calls to + `write' should be protected using cancellation handlers. - If `select' returns because the timeout period expires, it returns - a value of zero. + The `write' function is the underlying primitive for all of the + functions that write to streams, such as `fputc'. - Any signal will cause `select' to return immediately. So if your - program uses signals, you can't rely on `select' to keep waiting - for the full time specified. If you want to be sure of waiting - for a particular amount of time, you must check for `EINTR' and - repeat the `select' with a newly calculated timeout based on the - current time. See the example below. See also *Note Interrupted - Primitives::. + - Function: ssize_t pwrite (int FILEDES, const void *BUFFER, size_t + SIZE, off_t OFFSET) + The `pwrite' function is similar to the `write' function. The + first three arguments are identical, and the return values and + error codes also correspond. - If an error occurs, `select' returns `-1' and does not modify the - argument file descriptor sets. The following `errno' error - conditions are defined for this function: + The difference is the fourth argument and its handling.

The function call does not return unless all - actions have finished. + - Function: off_t lseek (int FILEDES, off_t OFFSET, int WHENCE) + The `lseek' function is used to change the file position of the + file with descriptor FILEDES. - A prototype for `fsync' can be found in `unistd.h'. + The WHENCE argument specifies how the OFFSET should be + interpreted, in the same way as for the `fseek' function, and it + must be one of the symbolic constants `SEEK_SET', `SEEK_CUR', or + `SEEK_END'. - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `fsync' is called.

Instead, use the `O_APPEND' operating mode; *note Operating + Modes::. - Not all systems implement the `fdatasync' operation. On systems - missing this functionality `fdatasync' is emulated by a call to - `fsync' since the performed actions are a superset of those - required by `fdatasync'. + You can set the file position past the current end of the file. + This does not by itself make the file longer; `lseek' never + changes the file. But subsequent output at that position will + extend the file. Characters between the previous end of file and + the new position are filled with zeros. Extending the file in + this way can create a "hole": the blocks of zeros are not actually + allocated on disk, so the file takes up less space than it appears + to; it is then called a "sparse file". - The prototype for `fdatasync' is in `unistd.h'. + If the file position cannot be changed, or the operation is in + some way invalid, `lseek' returns a value of -1. The following + `errno' error conditions are defined for this function: - The return value of the function is zero if no error occurred. - Otherwise it is -1 and the global variable ERRNO is set to the - following values: `EBADF' - The descriptor FILDES is not valid. + The FILEDES is not a valid file descriptor. `EINVAL' - No synchronization is possible since the system does not - implement this. - - -File: libc.info, Node: Asynchronous I/O, Next: Control Operations, Prev: Synchronizing I/O, Up: Low-Level I/O - -Perform I/O Operations in Parallel -================================== - - The POSIX.1b standard defines a new set of I/O operations which can -significantly reduce the time an application spends waiting at I/O. The -new functions allow a program to initiate one or more I/O operations and -then immediately resume normal work while the I/O operations are -executed in parallel. This functionality is available if the -`unistd.h' file defines the symbol `_POSIX_ASYNCHRONOUS_IO'. - - These functions are part of the library with realtime functions named -`librt'. They are not actually part of the `libc' binary. The -implementation of these functions can be done using support in the -kernel (if available) or using an implementation based on threads at -userlevel. In the latter case it might be necessary to link -applications with the thread library `libpthread' in addition to -`librt'. - - All AIO operations operate on files which were opened previously. -There might be arbitrarily many operations running for one file. The -asynchronous I/O operations are controlled using a data structure named -`struct aiocb' ("AIO control block"). It is defined in `aio.h' as -follows. - - - Data Type: struct aiocb - The POSIX.1b standard mandates that the `struct aiocb' structure - contains at least the members described in the following table. - There might be more elements which are used by the implementation, - but depending upon these elements is not portable and is highly - deprecated. - - `int aio_fildes' - This element specifies the file descriptor to be used for the - operation. It must be a legal descriptor, otherwise the - operation will fail. - - The device on which the file is opened must allow the seek - operation. I.e., it is not possible to use any of the AIO - operations on devices like terminals where an `lseek' call - would lead to an error. - - `off_t aio_offset' - This element specifies the offset in the file at which the - operation (input or output) is performed. Since the - operations are carried out in arbitrary order and more than - one operation for one file descriptor can be started, one - cannot expect a current read/write position of the file - descriptor. - - `volatile void *aio_buf' - This is a pointer to the buffer with the data to be written - or the place where the read data is stored. + The WHENCE argument value is not valid, or the resulting file + offset is not valid. A file offset is invalid. - `size_t aio_nbytes' - This element specifies the length of the buffer pointed to by - `aio_buf'. + `ESPIPE' + The FILEDES corresponds to an object that cannot be + positioned, such as a pipe, FIFO or terminal device. + (POSIX.1 specifies this error only for pipes and FIFOs, but + in the GNU system, you always get `ESPIPE' if the object is + not seekable.) - `int aio_reqprio' - If the platform has defined `_POSIX_PRIORITIZED_IO' and - `_POSIX_PRIORITY_SCHEDULING', the AIO requests are processed - based on the current scheduling priority. The `aio_reqprio' - element can then be used to lower the priority of the AIO - operation. + When the source file is compiled with `_FILE_OFFSET_BITS == 64' the + `lseek' function is in fact `lseek64' and the type `off_t' has 64 + bits which makes it possible to handle files up to 2^63 bytes in + length. - `struct sigevent aio_sigevent' - This element specifies how the calling process is notified - once the operation terminates. If the `sigev_notify' element - is `SIGEV_NONE', no notification is sent. If it is - `SIGEV_SIGNAL', the signal determined by `sigev_signo' is - sent. Otherwise, `sigev_notify' must be `SIGEV_THREAD'. In - this case, a thread is created which starts executing the - function pointed to by `sigev_notify_function'. + This function is a cancellation point in multi-threaded programs. + This is a problem if the thread allocates some resources (like + memory, file descriptors, semaphores or whatever) at the time + `lseek' is called. If the thread gets canceled these resources + stay allocated until the program ends. To avoid this calls to + `lseek' should be protected using cancellation handlers. - `int aio_lio_opcode' - This element is only used by the `lio_listio' and - `lio_listio64' functions. Since these functions allow an - arbitrary number of operations to start at once, and each - operation can be input or output (or nothing), the - information must be stored in the control block. The - possible values are: + The `lseek' function is the underlying primitive for the `fseek', + `fseeko', `ftell', `ftello' and `rewind' functions, which operate + on streams instead of file descriptors. - `LIO_READ' - Start a read operation. Read from the file at position - `aio_offset' and store the next `aio_nbytes' bytes in the - buffer pointed to by `aio_buf'. + - Function: off64_t lseek64 (int FILEDES, off64_t OFFSET, int WHENCE) + This function is similar to the `lseek' function. The difference + is that the OFFSET parameter is of type `off64_t' instead of + `off_t' which makes it possible on 32 bit machines to address + files larger than 2^31 bytes and up to 2^63 bytes. The file + descriptor `filedes' must be opened using `open64' since otherwise + the large offsets possible with `off64_t' will lead to errors with + a descriptor in small file mode. - `LIO_WRITE' - Start a write operation. Write `aio_nbytes' bytes - starting at `aio_buf' into the file starting at position - `aio_offset'. + When the source file is compiled with `_FILE_OFFSET_BITS == 64' on + a 32 bits machine this function is actually available under the + name `lseek' and so transparently replaces the 32 bit interface. - `LIO_NOP' - Do nothing for this control block. This value is useful - sometimes when an array of `struct aiocb' values - contains holes, i.e., some of the values must not be - handled although the whole array is presented to the - `lio_listio' function. + You can have multiple descriptors for the same file if you open the +file more than once, or if you duplicate a descriptor with `dup'. +Descriptors that come from separate calls to `open' have independent +file positions; using `lseek' on one descriptor has no effect on the +other. For example, - When the sources are compiled using `_FILE_OFFSET_BITS == 64' on a - 32 bit machine, this type is in fact `struct aiocb64', since the - LFS interface transparently replaces the `struct aiocb' definition. + { + int d1, d2; + char buf[4]; + d1 = open ("foo", O_RDONLY); + d2 = open ("foo", O_RDONLY); + lseek (d1, 1024, SEEK_SET); + read (d2, buf, 4); + } - For use with the AIO functions defined in the LFS, there is a -similar type defined which replaces the types of the appropriate -members with larger types but otherwise is equivalent to `struct -aiocb'. Particularly, all member names are the same. +will read the first four characters of the file `foo'. (The +error-checking code necessary for a real program has been omitted here +for brevity.) - - Data Type: struct aiocb64 - `int aio_fildes' - This element specifies the file descriptor which is used for - the operation. It must be a legal descriptor since otherwise - the operation fails for obvious reasons. + By contrast, descriptors made by duplication share a common file +position with the original descriptor that was duplicated. Anything +which alters the file position of one of the duplicates, including +reading or writing data, affects all of them alike. Thus, for example, - The device on which the file is opened must allow the seek - operation. I.e., it is not possible to use any of the AIO - operations on devices like terminals where an `lseek' call - would lead to an error. + { + int d1, d2, d3; + char buf1[4], buf2[4]; + d1 = open ("foo", O_RDONLY); + d2 = dup (d1); + d3 = dup (d2); + lseek (d3, 1024, SEEK_SET); + read (d1, buf1, 4); + read (d2, buf2, 4); + } - `off64_t aio_offset' - This element specifies at which offset in the file the - operation (input or output) is performed. Since the - operation are carried in arbitrary order and more than one - operation for one file descriptor can be started, one cannot - expect a current read/write position of the file descriptor. +will read four characters starting with the 1024'th character of `foo', +and then four more characters starting with the 1028'th character. - `volatile void *aio_buf' - This is a pointer to the buffer with the data to be written - or the place where the read data is stored. + - Data Type: off_t + This is an arithmetic data type used to represent file sizes. In + the GNU system, this is equivalent to `fpos_t' or `long int'. - `size_t aio_nbytes' - This element specifies the length of the buffer pointed to by - `aio_buf'. + If the source is compiled with `_FILE_OFFSET_BITS == 64' this type + is transparently replaced by `off64_t'. - `int aio_reqprio' - If for the platform `_POSIX_PRIORITIZED_IO' and - `_POSIX_PRIORITY_SCHEDULING' are defined the AIO requests are - processed based on the current scheduling priority. The - `aio_reqprio' element can then be used to lower the priority - of the AIO operation. + - Data Type: off64_t + This type is used similar to `off_t'. The difference is that even + on 32 bit machines, where the `off_t' type would have 32 bits, + `off64_t' has 64 bits and so is able to address files up to 2^63 + bytes in length. - `struct sigevent aio_sigevent' - This element specifies how the calling process is notified - once the operation terminates. If the `sigev_notify', - element is `SIGEV_NONE' no notification is sent. If it is - `SIGEV_SIGNAL', the signal determined by `sigev_signo' is - sent. Otherwise, `sigev_notify' must be `SIGEV_THREAD' in - which case a thread which starts executing the function - pointed to by `sigev_notify_function'. + When compiling with `_FILE_OFFSET_BITS == 64' this type is + available under the name `off_t'. - `int aio_lio_opcode' - This element is only used by the `lio_listio' and - `[lio_listio64' functions. Since these functions allow an - arbitrary number of operations to start at once, and since - each operation can be input or output (or nothing), the - information must be stored in the control block. See the - description of `struct aiocb' for a description of the - possible values. + These aliases for the `SEEK_...' constants exist for the sake of +compatibility with older BSD systems. They are defined in two +different header files: `fcntl.h' and `sys/file.h'. - When the sources are compiled using `_FILE_OFFSET_BITS == 64' on a - 32 bit machine, this type is available under the name `struct - aiocb64', since the LFS transparently replaces the old interface. +`L_SET' + An alias for `SEEK_SET'. -* Menu: +`L_INCR' + An alias for `SEEK_CUR'. -* Asynchronous Reads/Writes:: Asynchronous Read and Write Operations. -* Status of AIO Operations:: Getting the Status of AIO Operations. -* Synchronizing AIO Operations:: Getting into a consistent state. -* Cancel AIO Operations:: Cancellation of AIO Operations. -* Configuration of AIO:: How to optimize the AIO implementation. +`L_XTND' + An alias for `SEEK_END'.  -File: libc.info, Node: Asynchronous Reads/Writes, Next: Status of AIO Operations, Up: Asynchronous I/O - -Asynchronous Read and Write Operations --------------------------------------- - - - Function: int aio_read (struct aiocb *AIOCBP) - This function initiates an asynchronous read operation.

Possible error codes returned - by `aio_error' are: + Channels that come from a single opening share the same file +position; we call them "linked" channels. Linked channels result when +you make a stream from a descriptor using `fdopen', when you get a +descriptor from a stream with `fileno', when you copy a descriptor with +`dup' or `dup2', and when descriptors are inherited during `fork'. For +files that don't support random access, such as terminals and pipes, +_all_ channels are effectively linked.

The only - difference is that on 32 bit machines the file descriptor should - be opened in the large file mode. Internally `aio_write64' uses - functionality equivalent to `lseek64' (*note File Position - Primitive::) to position the file descriptor correctly for the - writing, as opposed to `lseek' functionality used in `aio_write'. + When you open channels (streams or descriptors) separately on a +seekable file, each channel has its own file position. These are called +"independent channels". - When the sources are compiled with `_FILE_OFFSET_BITS == 64', this - function is available under the name `aio_write' and so - transparently replaces the interface for small files on 32 bit - machines. + The system handles each channel independently. Most of the time, +this is quite predictable and natural (especially for input): each +channel can read or write sequentially at its own place in the file. +However, if some of the channels are streams, you must take these +precautions: - Besides these functions with the more or less traditional interface, -POSIX.1b also defines a function which can initiate more than one -operation at a time, and which can handle freely mixed read and write -operations. It is therefore similar to a combination of `readv' and -`writev'. + * You should clean an output stream after use, before doing anything + else that might read or write from the same part of the file. - - Function: int lio_listio (int MODE, struct aiocb *const LIST[], int - NENT, struct sigevent *SIG) - The `lio_listio' function can be used to enqueue an arbitrary - number of read and write requests at one time. The requests can - all be meant for the same file, all for different files or every - solution in between. + * You should clean an input stream before reading data that may have + been modified using an independent channel. Otherwise, you might + read obsolete data that had been in the stream's buffer. - `lio_listio' gets the NENT requests from the array pointed to by - LIST. The operation to be performed is determined by the - `aio_lio_opcode' member in each element of LIST. If this field is - `LIO_READ' a read operation is enqueued, similar to a call of - `aio_read' for this element of the array (except that the way the - termination is signalled is different, as we will see below). If - the `aio_lio_opcode' member is `LIO_WRITE' a write operation is - enqueued. Otherwise the `aio_lio_opcode' must be `LIO_NOP' in - which case this element of LIST is simply ignored. This - "operation" is useful in situations where one has a fixed array of - `struct aiocb' elements from which only a few need to be handled at - a time. Another situation is where the `lio_listio' call was - canceled before all requests are processed (*note Cancel AIO - Operations::) and the remaining requests have to be reissued. + If you do output to one channel at the end of the file, this will +certainly leave the other independent channels positioned somewhere +before the new end. You cannot reliably set their file positions to the +new end of file before writing, because the file can always be extended +by another process between when you set the file position and when you +write the data. Instead, use an append-type descriptor or stream; they +always output at the current end of the file. In order to make the +end-of-file position accurate, you must clean the output channel you +were using, if it is a stream. - The other members of each element of the array pointed to by - `list' must have values suitable for the operation as described in - the documentation for `aio_read' and `aio_write' above. + It's impossible for two channels to have separate file pointers for a +file that doesn't support random access. Thus, channels for reading or +writing such files are always linked, never independent. Append-type +channels are also always linked. For these channels, follow the rules +for linked channels; see *Note Linked Channels::. - The MODE argument determines how `lio_listio' behaves after having - enqueued all the requests. If MODE is `LIO_WAIT' it waits until - all requests terminated. Otherwise MODE must be `LIO_NOWAIT' and - in this case the function returns immediately after having - enqueued all the requests. In this case the caller gets a - notification of the termination of all requests according to the - SIG parameter.

To find out which - request or requests failed one has to use the `aio_error' function - on all the elements of the array LIST. +Cleaning Streams +---------------- - In case MODE is `LIO_NOWAIT', the function returns 0 if all - requests were enqueued correctly. The current state of the - requests can be found using `aio_error' and `aio_return' as - described above. If `lio_listio' returns -1 in this mode, the - global variable `errno' is set accordingly. If a request did not - yet terminate, a call to `aio_error' returns `EINPROGRESS'. If - the value is different, the request is finished and the error - value (or 0) is returned and the result of the operation can be - retrieved using `aio_return'. + On the GNU system, you can clean up any stream with `fclean': - Possible values for `errno' are: + - Function: int fclean (FILE *STREAM) + Clean up the stream STREAM so that its buffer is empty.

If STREAM is doing input, give the + data in the buffer back to the system, arranging to reread it. - `EAGAIN' - The resources necessary to queue all the requests are not - available at the moment. The error status for each element - of LIST must be checked to determine which request failed. + On other systems, you can use `fflush' to clean a stream in most +cases. - Another reason could be that the system wide limit of AIO - requests is exceeded. This cannot be the case for the - implementation on GNU systems since no arbitrary limits exist. + You can skip the `fclean' or `fflush' if you know the stream is +already clean. A stream is clean whenever its buffer is empty. For +example, an unbuffered stream is always clean. An input stream that is +at end-of-file is clean. A line-buffered stream is clean when the last +character output was a newline. - `EINVAL' - The MODE parameter is invalid or NENT is larger than - `AIO_LISTIO_MAX'. + There is one case in which cleaning a stream is impossible on most +systems. This is when the stream is doing input from a file that is not +random-access. Such streams typically read ahead, and when the file is +not random access, there is no way to give back the excess data already +read. When an input stream reads from a random-access file, `fflush' +does clean the stream, but leaves the file pointer at an unpredictable +place; you must set the file pointer before doing any further I/O. On +the GNU system, using `fclean' avoids both of these problems. - `EIO' - One or more of the request's I/O operations failed. The - error status of each request should be checked to determine - which one failed. + Closing an output-only stream also does `fflush', so this is a valid +way of cleaning an output stream. On the GNU system, closing an input +stream does `fclean'. - `ENOSYS' - The `lio_listio' function is not supported. + You need not clean a stream before using its descriptor for control +operations such as setting terminal modes; these operations don't affect +the file position and are not affected by it.

For example, some workstations may have devices +such as a digitizing tablet, function button box, or dial box that are +connected via normal asynchronous serial interfaces; good user interface +style requires responding immediately to input on any device. Another +example is a program that acts as a server to several other processes +via pipes or sockets. - - Macro: int F_DUPFD - This macro is used as the COMMAND argument to `fcntl', to copy the - file descriptor given as the first argument. + You cannot normally use `read' for this purpose, because this blocks +the program until input is available on one particular file descriptor; +input on other channels won't wake it up. You could set nonblocking +mode and poll each file descriptor in turn, but this is very +inefficient. - The form of the call in this case is: + A better solution is to use the `select' function.

On systems + with a fixed maximum number, `FD_SETSIZE' is at least that number. + On some systems, including GNU, there is no absolute limit on the + number of descriptors open, but this macro still has a constant + value which controls the number of bits in an `fd_set'; if you get + a file descriptor with a value as high as `FD_SETSIZE', you cannot + put that descriptor into an `fd_set'. - `EINVAL' - The NEXT-FILEDES argument is invalid. + - Macro: void FD_ZERO (fd_set *SET) + This macro initializes the file descriptor set SET to be the empty + set. - `EMFILE' - There are no more file descriptors available--your program is - already using the maximum.

Rather, they include + conditions such as the presence of an urgent message on a socket. + (*Note Sockets::, for information on urgent messages.) - "File descriptor flags" are miscellaneous attributes of a file -descriptor. These flags are associated with particular file -descriptors, so that if you have created duplicate file descriptors -from a single opening of a file, each descriptor has its own set of -flags. + The `select' function checks only the first NFDS file descriptors. + The usual thing is to pass `FD_SETSIZE' as the value of this + argument. - Currently there is just one file descriptor flag: `FD_CLOEXEC', -which causes the descriptor to be closed if you use any of the -`exec...' functions (*note Executing a File::). + The TIMEOUT specifies the maximum time to wait. If you pass a + null pointer for this argument, it means to block indefinitely + until one of the file descriptors is ready. Otherwise, you should + provide the time in `struct timeval' format; see *Note + High-Resolution Calendar::. Specify zero as the time (a `struct + timeval' containing all zeros) if you want to find out which + descriptors are ready without waiting if none are ready. - The symbols in this section are defined in the header file `fcntl.h'. + The normal return value from `select' is the total number of ready + file descriptors in all of the sets. Each of the argument sets is + overwritten with information about the descriptors that are ready + for the corresponding operation. Thus, to see if a particular + descriptor DESC has input, use `FD_ISSET (DESC, READ-FDS)' after + `select' returns. - - Macro: int F_GETFD - This macro is used as the COMMAND argument to `fcntl', to specify - that it should return the file descriptor flags associated with - the FILEDES argument. + If `select' returns because the timeout period expires, it returns + a value of zero. - The normal return value from `fcntl' with this command is a - nonnegative number which can be interpreted as the bitwise OR of - the individual flags (except that currently there is only one flag - to use). + Any signal will cause `select' to return immediately. So if your + program uses signals, you can't rely on `select' to keep waiting + for the full time specified. If you want to be sure of waiting + for a particular amount of time, you must check for `EINTR' and + repeat the `select' with a newly calculated timeout based on the + current time. See the example below. See also *Note Interrupted + Primitives::. - In case of an error, `fcntl' returns -1. The following `errno' - error conditions are defined for this command: + If an error occurs, `select' returns `-1' and does not modify the + argument file descriptor sets. The following `errno' error + conditions are defined for this function: `EBADF' - The FILEDES argument is invalid. - - - Macro: int F_SETFD - This macro is used as the COMMAND argument to `fcntl', to specify - that it should set the file descriptor flags associated with the - FILEDES argument. This requires a third `int' argument to specify - the new flags, so the form of the call is: - - fcntl (FILEDES, F_SETFD, NEW-FLAGS) + One of the file descriptor sets specified an invalid file + descriptor. - The normal return value from `fcntl' with this command is an - unspecified value other than -1, which indicates an error.

(In the GNU system, they can also allow none of -these, and allow execution of the file as a program.) The access modes -are chosen when the file is opened, and never change. +Synchronizing I/O operations +============================ - - Macro: int O_RDONLY - Open the file for read access. + In most modern operating systems, the normal I/O operations are not +executed synchronously. I.e., even if a `write' system call returns, +this does not mean the data is actually written to the media, e.g., the +disk. - - Macro: int O_WRONLY - Open the file for write access. + In situations where synchronization points are necessary, you can use +special functions which ensure that all operations finish before they +return. - - Macro: int O_RDWR - Open the file for both reading and writing. + - Function: int sync (void) + A call to this function will not return as long as there is data + which has not been written to the device. All dirty buffers in + the kernel will be written and so an overall consistent system can + be achieved (if no other process in parallel writes data). - In the GNU system (and not in other systems), `O_RDONLY' and -`O_WRONLY' are independent bits that can be bitwise-ORed together, and -it is valid for either bit to be set or clear. This means that -`O_RDWR' is the same as `O_RDONLY|O_WRONLY'. A file access mode of -zero is permissible; it allows no operations that do input or output to -the file, but does allow other operations such as `fchmod'. On the GNU -system, since "read-only" or "write-only" is a misnomer, `fcntl.h' -defines additional names for the file access modes. These names are -preferred when writing GNU-specific code. But most programs will want -to be portable to other POSIX.1 systems and should use the POSIX.1 -names above instead. + A prototype for `sync' can be found in `unistd.h'. - - Macro: int O_READ - Open the file for reading. Same as `O_RDWR'; only defined on GNU. + The return value is zero to indicate no error. - - Macro: int O_WRITE - Open the file for reading. Same as `O_WRONLY'; only defined on - GNU. + Programs more often want to ensure that data written to a given file +is committed, rather than all data in the system. For this, `sync' is +overkill. - - Macro: int O_EXEC - Open the file for executing. Only defined on GNU. + - Function: int fsync (int FILDES) + The `fsync' function can be used to make sure all data associated + with the open file FILDES is written to the device associated with + the descriptor. The function call does not return unless all + actions have finished. - To determine the file access mode with `fcntl', you must extract the -access mode bits from the retrieved file status flags. In the GNU -system, you can just test the `O_READ' and `O_WRITE' bits in the flags -word. But in other POSIX.1 systems, reading and writing access modes -are not stored as distinct bit flags. The portable way to extract the -file access mode bits is with `O_ACCMODE'. + A prototype for `fsync' can be found in `unistd.h'. - - Macro: int O_ACCMODE - This macro stands for a mask that can be bitwise-ANDed with the - file status flag value to produce a value representing the file - access mode. The mode will be `O_RDONLY', `O_WRONLY', or `O_RDWR'. - (In the GNU system it could also be zero, and it never includes the - `O_EXEC' bit.) + This function is a cancellation point in multi-threaded programs. + This is a problem if the thread allocates some resources (like + memory, file descriptors, semaphores or whatever) at the time + `fsync' is called. If the thread gets canceled these resources + stay allocated until the program ends. To avoid this, calls to + `fsync' should be protected using cancellation handlers. - -File: libc.info, Node: Open-time Flags, Next: Operating Modes, Prev: Access Modes, Up: File Status Flags + The return value of the function is zero if no error occurred. + Otherwise it is -1 and the global variable ERRNO is set to the + following values: + `EBADF' + The descriptor FILDES is not valid. -Open-time Flags ---------------- + `EINVAL' + No synchronization is possible since the system does not + implement this. - The open-time flags specify options affecting how `open' will behave. -These options are not preserved once the file is open. The exception to -this is `O_NONBLOCK', which is also an I/O operating mode and so it -_is_ saved. *Note Opening and Closing Files::, for how to call `open'. + Sometimes it is not even necessary to write all data associated with +a file descriptor. E.g., in database files which do not change in size +it is enough to write all the file content data to the device. +Meta-information, like the modification time etc., are not that +important and leaving such information uncommitted does not prevent a +successful recovering of the file in case of a problem. - There are two sorts of options specified by open-time flags. + - Function: int fdatasync (int FILDES) + When a call to the `fdatasync' function returns, it is ensured + that all of the file data is written to the device. For all + pending I/O operations, the parts guaranteeing data integrity + finished. - * "File name translation flags" affect how `open' looks up the file - name to locate the file, and whether the file can be created. + Not all systems implement the `fdatasync' operation. On systems + missing this functionality `fdatasync' is emulated by a call to + `fsync' since the performed actions are a superset of those + required by `fdatasync'. - * "Open-time action flags" specify extra operations that `open' will - perform on the file once it is open. + The prototype for `fdatasync' is in `unistd.h'. - Here are the file name translation flags. + The return value of the function is zero if no error occurred. + Otherwise it is -1 and the global variable ERRNO is set to the + following values: + `EBADF' + The descriptor FILDES is not valid. - - Macro: int O_CREAT - If set, the file will be created if it doesn't already exist. + `EINVAL' + No synchronization is possible since the system does not + implement this. - - Macro: int O_EXCL - If both `O_CREAT' and `O_EXCL' are set, then `open' fails if the - specified file already exists.

This is only meaningful for some kinds of files, usually - devices such as serial ports; when it is not meaningful, it is - harmless and ignored. Often opening a port to a modem blocks - until the modem reports carrier detection; if `O_NONBLOCK' is - specified, `open' will return immediately without a carrier. +Perform I/O Operations in Parallel +================================== - Note that the `O_NONBLOCK' flag is overloaded as both an I/O - operating mode and a file name translation flag. This means that - specifying `O_NONBLOCK' in `open' also sets nonblocking I/O mode; - *note Operating Modes::. To open the file without blocking but do - normal I/O that blocks, you must call `open' with `O_NONBLOCK' set - and then call `fcntl' to turn the bit off. + The POSIX.1b standard defines a new set of I/O operations which can +significantly reduce the time an application spends waiting at I/O. The +new functions allow a program to initiate one or more I/O operations and +then immediately resume normal work while the I/O operations are +executed in parallel. This functionality is available if the +`unistd.h' file defines the symbol `_POSIX_ASYNCHRONOUS_IO'. - - Macro: int O_NOCTTY - If the named file is a terminal device, don't make it the - controlling terminal for the process. *Note Job Control::, for - information about what it means to be the controlling terminal. + These functions are part of the library with realtime functions named +`librt'. They are not actually part of the `libc' binary. The +implementation of these functions can be done using support in the +kernel (if available) or using an implementation based on threads at +userlevel. In the latter case it might be necessary to link +applications with the thread library `libpthread' in addition to +`librt'. - In the GNU system and 4.4 BSD, opening a file never makes it the - controlling terminal and `O_NOCTTY' is zero. However, other - systems may use a nonzero value for `O_NOCTTY' and set the - controlling terminal when you open a file that is a terminal - device; so to be portable, use `O_NOCTTY' when it is important to - avoid this. + All AIO operations operate on files which were opened previously. +There might be arbitrarily many operations running for one file. The +asynchronous I/O operations are controlled using a data structure named +`struct aiocb' ("AIO control block"). It is defined in `aio.h' as +follows. - The following three file name translation flags exist only in the -GNU system. + - Data Type: struct aiocb + The POSIX.1b standard mandates that the `struct aiocb' structure + contains at least the members described in the following table. + There might be more elements which are used by the implementation, + but depending upon these elements is not portable and is highly + deprecated. - - Macro: int O_IGNORE_CTTY - Do not recognize the named file as the controlling terminal, even - if it refers to the process's existing controlling terminal - device. Operations on the new file descriptor will never induce - job control signals. *Note Job Control::. + `int aio_fildes' + This element specifies the file descriptor to be used for the + operation. It must be a legal descriptor, otherwise the + operation will fail. - - Macro: int O_NOLINK - If the named file is a symbolic link, open the link itself instead - of the file it refers to. (`fstat' on the new file descriptor will - return the information returned by `lstat' on the link's name.) + The device on which the file is opened must allow the seek + operation. I.e., it is not possible to use any of the AIO + operations on devices like terminals where an `lseek' call + would lead to an error. - - Macro: int O_NOTRANS - If the named file is specially translated, do not invoke the - translator. Open the bare file the translator itself sees. + `off_t aio_offset' + This element specifies the offset in the file at which the + operation (input or output) is performed. Since the + operations are carried out in arbitrary order and more than + one operation for one file descriptor can be started, one + cannot expect a current read/write position of the file + descriptor. - The open-time action flags tell `open' to do additional operations -which are not really related to opening the file. The reason to do them -as part of `open' instead of in separate calls is that `open' can do -them atomically. + `volatile void *aio_buf' + This is a pointer to the buffer with the data to be written + or the place where the read data is stored. - - Macro: int O_TRUNC - Truncate the file to zero length. This option is only useful for - regular files, not special files such as directories or FIFOs. - POSIX.1 requires that you open the file for writing to use - `O_TRUNC'. In BSD and GNU you must have permission to write the - file to truncate it, but you need not open for write access. + `size_t aio_nbytes' + This element specifies the length of the buffer pointed to by + `aio_buf'. - This is the only open-time action flag specified by POSIX.1. - There is no good reason for truncation to be done by `open', - instead of by calling `ftruncate' afterwards. The `O_TRUNC' flag - existed in Unix before `ftruncate' was invented, and is retained - for backward compatibility. + `int aio_reqprio' + If the platform has defined `_POSIX_PRIORITIZED_IO' and + `_POSIX_PRIORITY_SCHEDULING', the AIO requests are processed + based on the current scheduling priority. The `aio_reqprio' + element can then be used to lower the priority of the AIO + operation. - The remaining operating modes are BSD extensions. They exist only -on some systems. On other systems, these macros are not defined. + `struct sigevent aio_sigevent' + This element specifies how the calling process is notified + once the operation terminates. If the `sigev_notify' element + is `SIGEV_NONE', no notification is sent. If it is + `SIGEV_SIGNAL', the signal determined by `sigev_signo' is + sent. Otherwise, `sigev_notify' must be `SIGEV_THREAD'. In + this case, a thread is created which starts executing the + function pointed to by `sigev_notify_function'. - - Macro: int O_SHLOCK - Acquire a shared lock on the file, as with `flock'. *Note File - Locks::. + `int aio_lio_opcode' + This element is only used by the `lio_listio' and + `lio_listio64' functions. Since these functions allow an + arbitrary number of operations to start at once, and each + operation can be input or output (or nothing), the + information must be stored in the control block. The + possible values are: - If `O_CREAT' is specified, the locking is done atomically when - creating the file. You are guaranteed that no other process will - get the lock on the new file first. + `LIO_READ' + Start a read operation. Read from the file at position + `aio_offset' and store the next `aio_nbytes' bytes in the + buffer pointed to by `aio_buf'. - - Macro: int O_EXLOCK - Acquire an exclusive lock on the file, as with `flock'. *Note - File Locks::. This is atomic like `O_SHLOCK'. + `LIO_WRITE' + Start a write operation.

This value is useful + sometimes when an array of `struct aiocb' values + contains holes, i.e., some of the values must not be + handled although the whole array is presented to the + `lio_listio' function. -I/O Operating Modes -------------------- + When the sources are compiled using `_FILE_OFFSET_BITS == 64' on a + 32 bit machine, this type is in fact `struct aiocb64', since the + LFS interface transparently replaces the `struct aiocb' definition. - The operating modes affect how input and output operations using a -file descriptor work. These flags are set by `open' and can be fetched -and changed with `fcntl'. + For use with the AIO functions defined in the LFS, there is a +similar type defined which replaces the types of the appropriate +members with larger types but otherwise is equivalent to `struct +aiocb'. Particularly, all member names are the same. - - Macro: int O_APPEND - The bit that enables append mode for the file.

Unlike the input and output functions (*note I/O on Streams::; -*note Low-Level I/O::), these functions are concerned with operating on -the files themselves rather than on their contents. + When dealing with asynchronous operations it is sometimes necessary +to get into a consistent state. This would mean for AIO that one wants +to know whether a certain request or a group of request were processed. +This could be done by waiting for the notification sent by the system +after the operation terminated, but this sometimes would mean wasting +resources (mainly computation time). Instead POSIX.1b defines two +functions which will help with most kinds of consistency. - Among the facilities described in this chapter are functions for -examining or modifying directories, functions for renaming and deleting -files, and functions for examining and setting file attributes such as -access permissions and modification times. + The `aio_fsync' and `aio_fsync64' functions are only available if +the symbol `_POSIX_SYNCHRONIZED_IO' is defined in `unistd.h'. -* Menu: + - Function: int aio_fsync (int OP, struct aiocb *AIOCBP) + Calling this function forces all I/O operations operating queued + at the time of the function call operating on the file descriptor + `aiocbp->aio_fildes' into the synchronized I/O completion state + (*note Synchronizing I/O::). The `aio_fsync' function returns + immediately but the notification through the method described in + `aiocbp->aio_sigevent' will happen only after all requests for this + file descriptor have terminated and the file is synchronized. + This also means that requests for this very same file descriptor + which are queued after the synchronization request are not + affected. -* Working Directory:: This is used to resolve relative - file names. -* Accessing Directories:: Finding out what files a directory - contains. -* Working with Directory Trees:: Apply actions to all files or a selectable - subset of a directory hierarchy. -* Hard Links:: Adding alternate names to a file. -* Symbolic Links:: A file that ``points to'' a file name. -* Deleting Files:: How to delete a file, and what that means. -* Renaming Files:: Changing a file's name. -* Creating Directories:: A system call just for creating a directory. -* File Attributes:: Attributes of individual files. -* Making Special Files:: How to create special files. -* Temporary Files:: Naming and creating temporary files. + If OP is `O_DSYNC' the synchronization happens as with a call to + `fdatasync'.

Once the synchronization is done + `aio_error' return 0 if the synchronization was not successful. + Otherwise the value returned is the value to which the `fsync' or + `fdatasync' function would have set the `errno' variable. In this + case nothing can be assumed about the consistency for the data + written to this file descriptor. -Working Directory -================= + The return value of this function is 0 if the request was + successfully enqueued. Otherwise the return value is -1 and + `errno' is set to one of the following values: - Each process has associated with it a directory, called its "current -working directory" or simply "working directory", that is used in the -resolution of relative file names (*note File Name Resolution::). + `EAGAIN' + The request could not be enqueued due to temporary lack of + resources. - When you log in and begin a new session, your working directory is -initially set to the home directory associated with your login account -in the system user database. You can find any user's home directory -using the `getpwuid' or `getpwnam' functions; see *Note User Database::. + `EBADF' + The file descriptor `aiocbp->aio_fildes' is not valid or not + open for writing. - Users can change the working directory using shell commands like -`cd'. The functions described in this section are the primitives used -by those commands and by other programs for examining and changing the -working directory. + `EINVAL' + The implementation does not support I/O synchronization or + the OP parameter is other than `O_DSYNC' and `O_SYNC'. - Prototypes for these functions are declared in the header file -`unistd.h'. + `ENOSYS' + This function is not implemented. - - Function: char * getcwd (char *BUFFER, size_t SIZE) - The `getcwd' function returns an absolute file name representing - the current working directory, storing it in the character array - BUFFER that you provide.

Then `getcwd' - allocates a buffer automatically, as with `malloc' (*note - Unconstrained Allocation::). If the SIZE is greater than zero, - then the buffer is that large; otherwise, the buffer is as large - as necessary to hold the result. + - Function: int aio_fsync64 (int OP, struct aiocb64 *AIOCBP) + This function is similar to `aio_fsync' with the only difference + that the argument is a reference to a variable of type `struct + aiocb64'. - The return value is BUFFER on success and a null pointer on - failure.

This could be achieved by the +`aio_*' functions to notify the initiating process about the +termination but in some situations this is not the ideal solution. In +a program which constantly updates clients somehow connected to the +server it is not always the best solution to go round robin since some +connections might be slow. On the other hand letting the `aio_*' +function notify the caller might also be not the best solution since +whenever the process works on preparing data for on client it makes no +sense to be interrupted by a notification since the new client will not +be handled before the current client is served.

A value - of `-1' is returned to indicate an error. The `errno' error - conditions defined for this function are the usual file name - syntax errors (*note File Name Errors::), plus `ENOTDIR' if the - file FILENAME is not a directory. +Cancellation of AIO Operations +------------------------------ - - Function: int fchdir (int FILEDES) - This function is used to set the process's working directory to - directory associated with the file descriptor FILEDES. + When one or more requests are asynchronously processed, it might be +useful in some situations to cancel a selected operation, e.g., if it +becomes obvious that the written data is no longer accurate and would +have to be overwritten soon. As an example, assume an application, +which writes data in files in a situation where new incoming data would +have to be written in a file which will be updated by an enqueued +request. The POSIX AIO implementation provides such a function, but +this function is not capable of forcing the cancellation of the +request. It is up to the implementation to decide whether it is +possible to cancel the operation or not. Therefore using this function +is merely a hint. - The normal, successful return value from `fchdir' is `0'. A value - of `-1' is returned to indicate an error. The following `errno' - error conditions are defined for this function: + - Function: int aio_cancel (int FILDES, struct aiocb *AIOCBP) + The `aio_cancel' function can be used to cancel one or more + outstanding requests. If the AIOCBP parameter is `NULL', the + function tries to cancel all of the outstanding requests which + would process the file descriptor FILDES (i.e., whose `aio_fildes' + member is FILDES). If AIOCBP is not `NULL', `aio_cancel' attempts + to cancel the specific request pointed to by AIOCBP. - `EACCES' - Read permission is denied for the directory named by - `dirname'. + For requests which were successfully canceled, the normal + notification about the termination of the request should take + place. I.e., depending on the `struct sigevent' object which + controls this, nothing happens, a signal is sent or a thread is + started. If the request cannot be canceled, it terminates the + usual way after performing the operation. + + After a request is successfully canceled, a call to `aio_error' + with a reference to this request as the parameter will return + `ECANCELED' and a call to `aio_return' will return -1. If the + request wasn't canceled and is still running the error status is + still `EINPROGRESS'. + + The return value of the function is `AIO_CANCELED' if there were + requests which haven't terminated and which were successfully + canceled. If there is one or more requests left which couldn't be + canceled, the return value is `AIO_NOTCANCELED'. In this case + `aio_error' must be used to find out which of the, perhaps + multiple, requests (in AIOCBP is `NULL') weren't successfully + canceled. If all requests already terminated at the time + `aio_cancel' is called the return value is `AIO_ALLDONE'. + + If an error occurred during the execution of `aio_cancel' the + function returns -1 and sets `errno' to one of the following + values. `EBADF' - The FILEDES argument is not a valid file descriptor. + The file descriptor FILDES is not valid. - `ENOTDIR' - The file descriptor FILEDES is not associated with a - directory. + `ENOSYS' + `aio_cancel' is not implemented. - `EINTR' - The function call was interrupt by a signal. + When the sources are compiled with `_FILE_OFFSET_BITS == 64', this + function is in fact `aio_cancel64' since the LFS interface + transparently replaces the normal implementation. - `EIO' - An I/O error occurred. + - Function: int aio_cancel64 (int FILDES, struct aiocb64 *AIOCBP) + This function is similar to `aio_cancel' with the only difference + that the argument is a reference to a variable of type `struct + aiocb64'. + + When the sources are compiled with `_FILE_OFFSET_BITS == 64', this + function is available under the name `aio_cancel' and so + transparently replaces the interface for small files on 32 bit + machines.  -File: libc.info, Node: Accessing Directories, Next: Working with Directory Trees, Prev: Working Directory, Up: File System Interface +File: libc.info, Node: Configuration of AIO, Prev: Cancel AIO Operations, Up: Asynchronous I/O -Accessing Directories -===================== +How to optimize the AIO implementation +-------------------------------------- - The facilities described in this section let you read the contents -of a directory file. This is useful if you want your program to list -all the files in a directory, perhaps as part of a menu. + The POSIX standard does not specify how the AIO functions are +implemented. They could be system calls, but it is also possible to +emulate them at userlevel. - The `opendir' function opens a "directory stream" whose elements are -directory entries. You use the `readdir' function on the directory -stream to retrieve these entries, represented as `struct dirent' -objects. The name of the file for each entry is stored in the `d_name' -member of this structure. There are obvious parallels here to the -stream facilities for ordinary files, described in *Note I/O on -Streams::. + At the point of this writing, the available implementation is a +userlevel implementation which uses threads for handling the enqueued +requests. While this implementation requires making some decisions +about limitations, hard limitations are something which is best avoided +in the GNU C library. Therefore, the GNU C library provides a means +for tuning the AIO implementation according to the individual use. -* Menu: + - Data Type: struct aioinit + This data type is used to pass the configuration or tunable + parameters to the implementation.

Their - availability is always announced in the compilation environment by - a macro names `_DIRENT_HAVE_D_XXX' where XXX is replaced by the - name of the new member. For instance, the member `d_reclen' - available on some systems is announced through the macro - `_DIRENT_HAVE_D_RECLEN'. + `F_GETFL' + Get flags associated with the open file. *Note File Status + Flags::. - When a file has multiple names, each name has its own directory - entry.

If the thread gets canceled these resources + stay allocated until the program ends. To avoid this calls to + `fcntl' should be protected using cancellation handlers. - - Function: DIR * opendir (const char *DIRNAME) - The `opendir' function opens and returns a directory stream for - reading the directory whose file name is DIRNAME. The stream has - type `DIR *'. + +File: libc.info, Node: Duplicating Descriptors, Next: Descriptor Flags, Prev: Control Operations, Up: Low-Level I/O - If unsuccessful, `opendir' returns a null pointer. In addition to - the usual file name errors (*note File Name Errors::), the - following `errno' error conditions are defined for this function: +Duplicating Descriptors +======================= - `EACCES' - Read permission is denied for the directory named by - `dirname'. + You can "duplicate" a file descriptor, or allocate another file +descriptor that refers to the same open file as the original. Duplicate +descriptors share one file position and one set of file status flags +(*note File Status Flags::), but each has its own set of file descriptor +flags (*note Descriptor Flags::). - `EMFILE' - The process has too many files open. + The major use of duplicating a file descriptor is to implement +"redirection" of input or output: that is, to change the file or pipe +that a particular file descriptor corresponds to. - `ENFILE' - The entire system, or perhaps the file system which contains - the directory, cannot support any additional open files at - the moment. (This problem cannot happen on the GNU system.) + You can perform this operation using the `fcntl' function with the +`F_DUPFD' command, but there are also convenient functions `dup' and +`dup2' for duplicating descriptors. - The `DIR' type is typically implemented using a file descriptor, - and the `opendir' function in terms of the `open' function. *Note - Low-Level I/O::. Directory streams and the underlying file - descriptors are closed on `exec' (*note Executing a File::). + The `fcntl' function and flags are declared in `fcntl.h', while +prototypes for `dup' and `dup2' are in the header file `unistd.h'. - In some situations it can be desirable to get hold of the file -descriptor which is created by the `opendir' call. For instance, to -switch the current working directory to the directory just read the -`fchdir' function could be used. Historically the `DIR' type was -exposed and programs could access the fields. This does not happen in -the GNU C library. Instead a separate function is provided to allow -access. + - Function: int dup (int OLD) + This function copies descriptor OLD to the first available + descriptor number (the first number not currently open).

Some of the members of this data type (notably `d_ino') - might have a different size to allow large filesystems. +File Descriptor Flags +===================== - In all other aspects this function is equivalent to `readdir'. + "File descriptor flags" are miscellaneous attributes of a file +descriptor.

Don't assume that +the flags listed here are the only ones that are implemented; your +program may be run years from now and more flags may exist then. For +example, here is a function to set or clear the flag `FD_CLOEXEC' +without altering any other flags: + + /* Set the `FD_CLOEXEC' flag of DESC if VALUE is nonzero, + or clear the flag if VALUE is 0. + Return 0 on success, or -1 on error with `errno' set. */ int - main (void) + set_cloexec_flag (int desc, int value) { - DIR *dp; - struct dirent *ep; - - dp = opendir ("./"); - if (dp != NULL) - { - while (ep = readdir (dp)) - puts (ep->d_name); - (void) closedir (dp); - } + int oldflags = fcntl (desc, F_GETFD, 0); + /* If reading the flags failed, return error indication now. + if (oldflags < 0) + return oldflags; + /* Set just the flag we want to set. */ + if (value != 0) + oldflags |= FD_CLOEXEC; else - perror ("Couldn't open the directory"); - - return 0; + oldflags &= ~FD_CLOEXEC; + /* Store modified flag word in the descriptor. */ + return fcntl (desc, F_SETFD, oldflags); } - The order in which files appear in a directory tends to be fairly -random.

This - function also notices if files have been added or removed to the - directory since it was opened with `opendir'. (Entries for these - files might or might not be returned by `readdir' if they were - added or removed since you last called `opendir' or `rewinddir'.) + - Macro: int O_RDONLY + Open the file for read access. - - Function: off_t telldir (DIR *DIRSTREAM) - The `telldir' function returns the file position of the directory - stream DIRSTREAM.

This means that +`O_RDWR' is the same as `O_RDONLY|O_WRONLY'. A file access mode of +zero is permissible; it allows no operations that do input or output to +the file, but does allow other operations such as `fchmod'. On the GNU +system, since "read-only" or "write-only" is a misnomer, `fcntl.h' +defines additional names for the file access modes. These names are +preferred when writing GNU-specific code.

The portable way to extract the +file access mode bits is with `O_ACCMODE'. + + - Macro: int O_ACCMODE + This macro stands for a mask that can be bitwise-ANDed with the + file status flag value to produce a value representing the file + access mode.

The result in *NAMELIST is an array of pointers to - structure of type `struct dirent' which describe all selected - directory entries and which is allocated using `malloc'.

For the convenience of the -programmer the GNU C library contains implementations of functions which -are very helpful for this purpose. + Here are the file name translation flags. - - Function: int alphasort (const void *A, const void *B) - The `alphasort' function behaves like the `strcoll' function - (*note String/Array Comparison::).

This flag is returned - instead of `FTW_D' if the `FTW_DEPTH' flag is passed to - `nftw' (see below). + The normal return value from `fcntl' with this command is a + nonnegative number which can be interpreted as the bitwise OR of + the individual flags. Since the file access modes are not + single-bit values, you can mask off other bits in the returned + flags with `O_ACCMODE' to compare them. - `FTW_SLN' - The current item is a stale symbolic link. The file it - points to does not exist. + In case of an error, `fcntl' returns -1. The following `errno' + error conditions are defined for this command: - The last parameter of the callback function is a pointer to a - structure with some extra information as described below. + `EBADF' + The FILEDES argument is invalid. - If the sources are compiled with `_FILE_OFFSET_BITS == 64' this - type is in fact `__nftw64_func_t' since this mode changes `struct - stat' to be `struct stat64'. + - Macro: int F_SETFL + This macro is used as the COMMAND argument to `fcntl', to set the + file status flags for the open file corresponding to the FILEDES + argument.

The second - parameter to the function is this time a pointer to a variable of - type `struct stat64' which is able to represent the larger values. + The normal return value from `fcntl' with this command is an + unspecified value other than -1, which indicates an error. The + error conditions are the same as for the `F_GETFL' command. - - Data Type: struct FTW - The information contained in this structure helps in interpreting - the name parameter and gives some information about the current - state of the traversal of the directory hierarchy. + If you want to modify the file status flags, you should get the +current flags with `F_GETFL' and modify the value. Don't assume that +the flags listed here are the only ones that are implemented; your +program may be run years from now and more flags may exist then. For +example, here is a function to set or clear the flag `O_NONBLOCK' +without altering any other flags: - `int base' - The value is the offset into the string passed in the first - parameter to the callback function of the beginning of the - file name. The rest of the string is the path of the file. - This information is especially important if the `FTW_CHDIR' - flag was set in calling `nftw' since then the current - directory is the one the current item is found in. + /* Set the `O_NONBLOCK' flag of DESC if VALUE is nonzero, + or clear the flag if VALUE is 0. + Return 0 on success, or -1 on error with `errno' set. */ + + int + set_nonblock_flag (int desc, int value) + { + int oldflags = fcntl (desc, F_GETFL, 0); + /* If reading the flags failed, return error indication now. */ + if (oldflags == -1) + return -1; + /* Set just the flag we want to set. */ + if (value != 0) + oldflags |= O_NONBLOCK; + else + oldflags &= ~O_NONBLOCK; + /* Store modified flag word in the descriptor. */ + return fcntl (desc, F_SETFL, oldflags); + } - `int level' - Whilst processing, the code tracks how many directories down - it has gone to find the current file. This nesting level - starts at 0 for files in the initial directory (or is zero - for the initial file if a file was passed). + +File: libc.info, Node: File Locks, Next: Interrupt Input, Prev: File Status Flags, Up: Low-Level I/O - - Function: int ftw (const char *FILENAME, __ftw_func_t FUNC, int - DESCRIPTORS) - The `ftw' function calls the callback function given in the - parameter FUNC for every item which is found in the directory - specified by FILENAME and all directories below. The function - follows symbolic links if necessary but does not process an item - twice. If FILENAME is not a directory then it itself is the only - object returned to the callback function. +File Locks +========== - The file name passed to the callback function is constructed by - taking the FILENAME parameter and appending the names of all passed - directories and then the local file name. So the callback - function can use this parameter to access the file. `ftw' also - calls `stat' for the file and passes that information on to the - callback function. If this `stat' call was not successful the - failure is indicated by setting the third argument of the callback - function to `FTW_NS'. Otherwise it is set according to the - description given in the account of `__ftw_func_t' above. + The remaining `fcntl' commands are used to support "record locking", +which permits multiple cooperating programs to prevent each other from +simultaneously accessing parts of a file in error-prone ways. - The callback function is expected to return 0 to indicate that no - error occurred and that processing should continue. If an error - occurred in the callback function or it wants `ftw' to return - immediately, the callback function can return a value other than - 0. This is the only correct way to stop the function. The - program must not use `setjmp' or similar techniques to continue - from another place. This would leave resources allocated by the - `ftw' function unfreed. + An "exclusive" or "write" lock gives a process exclusive access for +writing to the specified part of the file. While a write lock is in +place, no other process can lock that part of the file. - The DESCRIPTORS parameter to `ftw' specifies how many file - descriptors it is allowed to consume. The function runs faster - the more descriptors it can use. For each level in the directory - hierarchy at most one descriptor is used, but for very deep ones - any limit on open file descriptors for the process or the system - may be exceeded. Moreover, file descriptor limits in a - multi-threaded program apply to all the threads as a group, and - therefore it is a good idea to supply a reasonable limit to the - number of open descriptors. + A "shared" or "read" lock prohibits any other process from +requesting a write lock on the specified part of the file. However, +other processes can request read locks. - The return value of the `ftw' function is 0 if all callback - function calls returned 0 and all actions performed by the `ftw' - succeeded. If a function call failed (other than calling `stat' - on an item) the function returns -1. If a callback function - returns a value other than 0 this value is returned as the return - value of `ftw'. + The `read' and `write' functions do not actually check to see +whether there are any locks in place. If you want to implement a +locking protocol for a file shared by multiple processes, your +application must do explicit `fcntl' calls to request and clear locks +at the appropriate points. - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `ftw64', i.e. the LFS - interface transparently replaces the old interface. + Locks are associated with processes. A process can only have one +kind of lock set for each byte of a given file. When any file +descriptor for that file is closed by the process, all of the locks +that process holds on that file are released, even if the locks were +made using other descriptors that remain open. Likewise, locks are +released when a process exits, and are not inherited by child processes +created using `fork' (*note Creating a Process::). - - Function: int ftw64 (const char *FILENAME, __ftw64_func_t FUNC, int - DESCRIPTORS) - This function is similar to `ftw' but it can work on filesystems - with large files. File information is reported using a variable - of type `struct stat64' which is passed by reference to the - callback function. + When making a lock, use a `struct flock' to specify what kind of +lock and where. This data type and the associated macros for the +`fcntl' function are declared in the header file `fcntl.h'. - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is available under the name `ftw' and - transparently replaces the old implementation. + - Data Type: struct flock + This structure is used with the `fcntl' function to describe a file + lock. It has these members: - - Function: int nftw (const char *FILENAME, __nftw_func_t FUNC, int - DESCRIPTORS, int FLAG) - The `nftw' function works like the `ftw' functions. They call the - callback function FUNC for all items found in the directory - FILENAME and below. At most DESCRIPTORS file descriptors are - consumed during the `nftw' call. + `short int l_type' + Specifies the type of the lock; one of `F_RDLCK', `F_WRLCK', + or `F_UNLCK'. - One difference is that the callback function is of a different - type. It is of type `struct FTW *' and provides the callback - function with the extra information described above. + `short int l_whence' + This corresponds to the WHENCE argument to `fseek' or + `lseek', and specifies what the offset is relative to. Its + value can be one of `SEEK_SET', `SEEK_CUR', or `SEEK_END'. - A second difference is that `nftw' takes a fourth argument, which - is 0 or a bitwise-OR combination of any of the following values. + `off_t l_start' + This specifies the offset of the start of the region to which + the lock applies, and is given in bytes relative to the point + specified by `l_whence' member. - `FTW_PHYS' - While traversing the directory symbolic links are not - followed. Instead symbolic links are reported using the - `FTW_SL' value for the type parameter to the callback - function. If the file referenced by a symbolic link does not - exist `FTW_SLN' is returned instead. + `off_t l_len' + This specifies the length of the region to be locked. A + value of `0' is treated specially; it means the region + extends to the end of the file. - `FTW_MOUNT' - The callback function is only called for items which are on - the same mounted filesystem as the directory given by the - FILENAME parameter to `nftw'. + `pid_t l_pid' + This field is the process ID (*note Process Creation + Concepts::) of the process holding the lock. It is filled in + by calling `fcntl' with the `F_GETLK' command, but is ignored + when making a lock. - `FTW_CHDIR' - If this flag is given the current working directory is - changed to the directory of the reported object before the - callback function is called. When `ntfw' finally returns the - current directory is restored to its original value. + - Macro: int F_GETLK + This macro is used as the COMMAND argument to `fcntl', to specify + that it should get information about a lock. This command + requires a third argument of type `struct flock *' to be passed to + `fcntl', so that the form of the call is: - `FTW_DEPTH' - If this option is specified then all subdirectories and files - within them are processed before processing the top directory - itself (depth-first processing). This also means the type - flag given to the callback function is `FTW_DP' and not - `FTW_D'. + fcntl (FILEDES, F_GETLK, LOCKP) - The return value is computed in the same way as for `ftw'. `nftw' - returns 0 if no failures occurred and all callback functions - returned 0. In case of internal errors, such as memory problems, - the return value is -1 and ERRNO is set accordingly. If the - return value of a callback invocation was non-zero then that value - is returned. + If there is a lock already in place that would block the lock + described by the LOCKP argument, information about that lock + overwrites `*LOCKP'. Existing locks are not reported if they are + compatible with making a new lock as specified. Thus, you should + specify a lock type of `F_WRLCK' if you want to find out about both + read and write locks, or `F_RDLCK' if you want to find out about + write locks only. - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `nftw64', i.e. the LFS - interface transparently replaces the old interface. + There might be more than one lock affecting the region specified + by the LOCKP argument, but `fcntl' only returns information about + one of them. The `l_whence' member of the LOCKP structure is set + to `SEEK_SET' and the `l_start' and `l_len' fields set to identify + the locked region. - - Function: int nftw64 (const char *FILENAME, __nftw64_func_t FUNC, - int DESCRIPTORS, int FLAG) - This function is similar to `nftw' but it can work on filesystems - with large files. File information is reported using a variable - of type `struct stat64' which is passed by reference to the - callback function. + If no lock applies, the only change to the LOCKP structure is to + update the `l_type' to a value of `F_UNLCK'. - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is available under the name `nftw' and - transparently replaces the old implementation. + The normal return value from `fcntl' with this command is an + unspecified value other than -1, which is reserved to indicate an + error. The following `errno' error conditions are defined for + this command: - -File: libc.info, Node: Hard Links, Next: Symbolic Links, Prev: Working with Directory Trees, Up: File System Interface + `EBADF' + The FILEDES argument is invalid. -Hard Links -========== + `EINVAL' + Either the LOCKP argument doesn't specify valid lock + information, or the file associated with FILEDES doesn't + support locks. - In POSIX systems, one file can have many names at the same time. -All of the names are equally real, and no one of them is preferred to -the others. + - Macro: int F_SETLK + This macro is used as the COMMAND argument to `fcntl', to specify + that it should set or clear a lock. This command requires a third + argument of type `struct flock *' to be passed to `fcntl', so that + the form of the call is: - To add a name to a file, use the `link' function. (The new name is -also called a "hard link" to the file.) Creating a new link to a file -does not copy the contents of the file; it simply makes a new name by -which the file can be known, in addition to the file's existing name or -names. + fcntl (FILEDES, F_SETLK, LOCKP) - One file can have names in several directories, so the organization -of the file system is not a strict hierarchy or tree. + If the process already has a lock on any part of the region, the + old lock on that part is replaced with the new lock. You can + remove a lock by specifying a lock type of `F_UNLCK'. - In most implementations, it is not possible to have hard links to the -same file in multiple file systems. `link' reports an error if you try -to make a hard link to the file from another file system when this -cannot be done. + If the lock cannot be set, `fcntl' returns immediately with a value + of -1. This function does not block waiting for other processes + to release locks. If `fcntl' succeeds, it return a value other + than -1. - The prototype for the `link' function is declared in the header file -`unistd.h'. + The following `errno' error conditions are defined for this + function: - - Function: int link (const char *OLDNAME, const char *NEWNAME) - The `link' function makes a new link to the existing file named by - OLDNAME, under the new name NEWNAME. + `EAGAIN' + `EACCES' + The lock cannot be set because it is blocked by an existing + lock on the file. Some systems use `EAGAIN' in this case, + and other systems use `EACCES'; your program should treat + them alike, after `F_SETLK'. (The GNU system always uses + `EAGAIN'.) - This function returns a value of `0' if it is successful and `-1' - on failure. In addition to the usual file name errors (*note File - Name Errors::) for both OLDNAME and NEWNAME, the following `errno' - error conditions are defined for this function: + `EBADF' + Either: the FILEDES argument is invalid; you requested a read + lock but the FILEDES is not open for read access; or, you + requested a write lock but the FILEDES is not open for write + access. - `EACCES' - You are not allowed to write to the directory in which the - new link is to be written. + `EINVAL' + Either the LOCKP argument doesn't specify valid lock + information, or the file associated with FILEDES doesn't + support locks. - `EEXIST' - There is already a file named NEWNAME. If you want to replace - this link with a new link, you must remove the old link - explicitly first. + `ENOLCK' + The system has run out of file lock resources; there are + already too many file locks in place. - `EMLINK' - There are already too many links to the file named by OLDNAME. - (The maximum number of links to a file is `LINK_MAX'; see - *Note Limits for Files::.) + Well-designed file systems never report this error, because + they have no limitation on the number of locks. However, you + must still take account of the possibility of this error, as + it could result from network access to a file system on + another machine. - `ENOENT' - The file named by OLDNAME doesn't exist. You can't make a - link to a file that doesn't exist. + - Macro: int F_SETLKW + This macro is used as the COMMAND argument to `fcntl', to specify + that it should set or clear a lock. It is just like the `F_SETLK' + command, but causes the process to block (or wait) until the + request can be specified. - `ENOSPC' - The directory or file system that would contain the new link - is full and cannot be extended. + This command requires a third argument of type `struct flock *', as + for the `F_SETLK' command. - `EPERM' - In the GNU system and some others, you cannot make links to - directories. Many systems allow only privileged users to do - so. This error is used to report the problem. + The `fcntl' return values and errors are the same as for the + `F_SETLK' command, but these additional `errno' error conditions + are defined for this command: - `EROFS' - The directory containing the new link can't be modified - because it's on a read-only file system. + `EINTR' + The function was interrupted by a signal while it was waiting. + *Note Interrupted Primitives::. - `EXDEV' - The directory specified in NEWNAME is on a different file - system than the existing file. + `EDEADLK' + The specified region is being locked by another process. But + that process is waiting to lock a region which the current + process has locked, so waiting for the lock would result in + deadlock. The system does not guarantee that it will detect + all such conditions, but it lets you know if it notices one. - `EIO' - A hardware error occurred while trying to read or write the - to filesystem. + The following macros are defined for use as values for the `l_type' +member of the `flock' structure. The values are integer constants. - -File: libc.info, Node: Symbolic Links, Next: Deleting Files, Prev: Hard Links, Up: File System Interface +`F_RDLCK' + This macro is used to specify a read (or shared) lock. -Symbolic Links -============== +`F_WRLCK' + This macro is used to specify a write (or exclusive) lock. - The GNU system supports "soft links" or "symbolic links". This is a -kind of "file" that is essentially a pointer to another file name. -Unlike hard links, symbolic links can be made to directories or across -file systems with no restrictions. You can also make a symbolic link -to a name which is not the name of any file. (Opening this link will -fail until a file by that name is created.) Likewise, if the symbolic -link points to an existing file which is later deleted, the symbolic -link continues to point to the same file name even though the name no -longer names any file. +`F_UNLCK' + This macro is used to specify that the region is unlocked. - The reason symbolic links work the way they do is that special things -happen when you try to open the link. The `open' function realizes you -have specified the name of a link, reads the file name contained in the -link, and opens that file name instead. The `stat' function likewise -operates on the file that the symbolic link points to, instead of on -the link itself. + As an example of a situation where file locking is useful, consider a +program that can be run simultaneously by several different users, that +logs status information to a common file. One example of such a program +might be a game that uses a file to keep track of high scores. Another +example might be a program that records usage or accounting information +for billing purposes. - By contrast, other operations such as deleting or renaming the file -operate on the link itself. The functions `readlink' and `lstat' also -refrain from following symbolic links, because their purpose is to -obtain information about the link. `link', the function that makes a -hard link, does too. It makes a hard link to the symbolic link, which -one rarely wants. + Having multiple copies of the program simultaneously writing to the +file could cause the contents of the file to become mixed up. But you +can prevent this kind of problem by setting a write lock on the file +before actually writing to the file. - Some systems have for some functions operating on files have a limit -on how many symbolic links are followed when resolving a path name. The -limit if it exists is published in the `sys/param.h' header file. + If the program also needs to read the file and wants to make sure +that the contents of the file are in a consistent state, then it can +also use a read lock. While the read lock is set, no other process can +lock that part of the file for writing. - - Macro: int MAXSYMLINKS - The macro `MAXSYMLINKS' specifies how many symlinks some function - will follow before returning `ELOOP'. Not all functions behave the - same and this value is not the same a that returned for - `_SC_SYMLOOP' by `sysconf'. In fact, the `sysconf' result can - indicate that there is no fixed limit although `MAXSYMLINKS' - exists and has a finite value. + Remember that file locks are only a _voluntary_ protocol for +controlling access to a file. There is still potential for access to +the file by programs that don't use the lock protocol. - Prototypes for most of the functions listed in this section are in -`unistd.h'. + +File: libc.info, Node: Interrupt Input, Next: IOCTLs, Prev: File Locks, Up: Low-Level I/O - - Function: int symlink (const char *OLDNAME, const char *NEWNAME) - The `symlink' function makes a symbolic link to OLDNAME named - NEWNAME. +Interrupt-Driven Input +====================== - The normal return value from `symlink' is `0'. A return value of - `-1' indicates an error. In addition to the usual file name - syntax errors (*note File Name Errors::), the following `errno' - error conditions are defined for this function: + If you set the `O_ASYNC' status flag on a file descriptor (*note +File Status Flags::), a `SIGIO' signal is sent whenever input or output +becomes possible on that file descriptor. The process or process group +to receive the signal can be selected by using the `F_SETOWN' command +to the `fcntl' function. If the file descriptor is a socket, this also +selects the recipient of `SIGURG' signals that are delivered when +out-of-band data arrives on that socket; see *Note Out-of-Band Data::. +(`SIGURG' is sent in any situation where `select' would report the +socket as having an "exceptional condition". *Note Waiting for I/O::.) - `EEXIST' - There is already an existing file named NEWNAME. + If the file descriptor corresponds to a terminal device, then `SIGIO' +signals are sent to the foreground process group of the terminal. +*Note Job Control::. - `EROFS' - The file NEWNAME would exist on a read-only file system. + The symbols in this section are defined in the header file `fcntl.h'. - `ENOSPC' - The directory or file system cannot be extended to make the - new link. + - Macro: int F_GETOWN + This macro is used as the COMMAND argument to `fcntl', to specify + that it should get information about the process or process group + to which `SIGIO' signals are sent.

Here is an example: + - Macro: int F_SETOWN + This macro is used as the COMMAND argument to `fcntl', to specify + that it should set the process or process group to which `SIGIO' + signals are sent. This command requires a third argument of type + `pid_t' to be passed to `fcntl', so that the form of the call is: - char * - readlink_malloc (const char *filename) - { - int size = 100; - - while (1) - { - char *buffer = (char *) xmalloc (size); - int nchars = readlink (filename, buffer, size); - if (nchars < 0) - return NULL; - if (nchars < size) - return buffer; - free (buffer); - size *= 2; - } - } + fcntl (FILEDES, F_SETOWN, PID) - A value of `-1' is returned in case of error. In addition to the - usual file name errors (*note File Name Errors::), the following - `errno' error conditions are defined for this function: + The PID argument should be a process ID. You can also pass a + negative number whose absolute value is a process group ID. - `EINVAL' - The named file is not a symbolic link. + The return value from `fcntl' with this command is -1 in case of + error and some other value if successful.

The - file formerly accessible under the name OLDNAME is afterwards - accessible as NEWNAME instead.

The consistent way to handle this case - is to delete OLDNAME. However, in this case POSIX requires that - `rename' do nothing and report success--which is inconsistent. We - don't know what your operating system will do. +Working Directory +================= - If OLDNAME is not a directory, then any existing file named - NEWNAME is removed during the renaming operation. However, if - NEWNAME is the name of a directory, `rename' fails in this case. + Each process has associated with it a directory, called its "current +working directory" or simply "working directory", that is used in the +resolution of relative file names (*note File Name Resolution::). - If OLDNAME is a directory, then either NEWNAME must not exist or - it must name a directory that is empty. In the latter case, the - existing directory named NEWNAME is deleted first. The name - NEWNAME must not specify a subdirectory of the directory `oldname' - which is being renamed. + When you log in and begin a new session, your working directory is +initially set to the home directory associated with your login account +in the system user database. You can find any user's home directory +using the `getpwuid' or `getpwnam' functions; see *Note User Database::. - One useful feature of `rename' is that the meaning of NEWNAME - changes "atomically" from any previously existing file by that - name to its new meaning (i.e. the file that was called OLDNAME). - There is no instant at which NEWNAME is non-existent "in between" - the old meaning and the new meaning. If there is a system crash - during the operation, it is possible for both names to still - exist; but NEWNAME will always be intact if it exists at all. + Users can change the working directory using shell commands like +`cd'. The functions described in this section are the primitives used +by those commands and by other programs for examining and changing the +working directory. - If `rename' fails, it returns `-1'. In addition to the usual file - name errors (*note File Name Errors::), the following `errno' - error conditions are defined for this function: + Prototypes for these functions are declared in the header file +`unistd.h'. - `EACCES' - One of the directories containing NEWNAME or OLDNAME refuses - write permission; or NEWNAME and OLDNAME are directories and - write permission is refused for one of them. + - Function: char * getcwd (char *BUFFER, size_t SIZE) + The `getcwd' function returns an absolute file name representing + the current working directory, storing it in the character array + BUFFER that you provide.

Then `getcwd' + allocates a buffer automatically, as with `malloc' (*note + Unconstrained Allocation::). If the SIZE is greater than zero, + then the buffer is that large; otherwise, the buffer is as large + as necessary to hold the result. - `ENOTEMPTY' - `EEXIST' - The directory NEWNAME isn't empty.

For details about access permissions see -*Note Permission Bits::. +Random Access in a Directory Stream +----------------------------------- - There are two ways you can access the file type information in a file -mode. Firstly, for each file type there is a "predicate macro" which -examines a given file mode and returns whether it is of that type or -not. Secondly, you can mask out the rest of the file mode to leave -just the file type code, and compare this against constants for each of -the supported file types. + This section describes how to reread parts of a directory that you +have already read from an open directory stream.

The value POS must be the result of a + previous call to `telldir' on this particular stream; closing and + reopening the directory can invalidate values returned by + `telldir'. - - Macro: int S_ISCHR (mode_t M) - This macro returns non-zero if the file is a character special - file (a device like a terminal). + +File: libc.info, Node: Scanning Directory Content, Next: Simple Directory Lister Mark II, Prev: Random Access Directory, Up: Accessing Directories - - Macro: int S_ISBLK (mode_t M) - This macro returns non-zero if the file is a block special file (a - device like a disk). +Scanning the Content of a Directory +----------------------------------- - - Macro: int S_ISREG (mode_t M) - This macro returns non-zero if the file is a regular file. + A higher-level interface to the directory handling functions is the +`scandir' function.

The result in *NAMELIST is an array of pointers to + structure of type `struct dirent' which describe all selected + directory entries and which is allocated using `malloc'.

Each file also has a "group" which is one of -the defined groups. The file owner can often be useful for showing you -who edited the file (especially when you edit with GNU Emacs), but its -main purpose is for access control. + The functions described so far for handling the files in a directory +have allowed you to either retrieve the information bit by bit, or to +process all the files as a group (see `scandir'). Sometimes it is +useful to process whole hierarchies of directories and their contained +files. The X/Open specification defines two functions to do this. The +simpler form is derived from an early definition in System V systems +and therefore this function is available on SVID-derived systems. The +prototypes and required definitions can be found in the `ftw.h' header. - The file owner and group play a role in determining access because -the file has one set of access permission bits for the owner, another -set that applies to users who belong to the file's group, and a third -set of bits that applies to everyone else. *Note Access Permission::, -for the details of how access is decided based on this data. + There are four functions in this family: `ftw', `nftw' and their +64-bit counterparts `ftw64' and `nftw64'. These functions take as one +of their arguments a pointer to a callback function of the appropriate +type. - When a file is created, its owner is set to the effective user ID of -the process that creates it (*note Process Persona::). The file's -group ID may be set to either the effective group ID of the process, or -the group ID of the directory that contains the file, depending on the -system where the file is stored. When you access a remote file system, -it behaves according to its own rules, not according to the system your -program is running on. Thus, your program must be prepared to encounter -either kind of behavior no matter what kind of system you run it on. + - Data Type: __ftw_func_t + int (*) (const char *, const struct stat *, int) - You can change the owner and/or group owner of an existing file using -the `chown' function. This is the primitive for the `chown' and -`chgrp' shell commands. + The type of callback functions given to the `ftw' function. The + first parameter points to the file name, the second parameter to an + object of type `struct stat' which is filled in for the file named + in the first parameter. - The prototype for this function is declared in `unistd.h'. + The last parameter is a flag giving more information about the + current file. It can have the following values: - - Function: int chown (const char *FILENAME, uid_t OWNER, gid_t GROUP) - The `chown' function changes the owner of the file FILENAME to - OWNER, and its group owner to GROUP. + `FTW_F' + The item is either a normal file or a file which does not fit + into one of the following categories. This could be special + files, sockets etc. - Changing the owner of the file on certain systems clears the - set-user-ID and set-group-ID permission bits. (This is because - those bits may not be appropriate for the new owner.) Other file - permission bits are not changed. + `FTW_D' + The item is a directory. - The return value is `0' on success and `-1' on failure. In - addition to the usual file name errors (*note File Name Errors::), - the following `errno' error conditions are defined for this - function: + `FTW_NS' + The `stat' call failed and so the information pointed to by + the second paramater is invalid. - `EPERM' - This process lacks permission to make the requested change. + `FTW_DNR' + The item is a directory which cannot be read. - Only privileged users or the file's owner can change the - file's group. On most file systems, only privileged users - can change the file owner; some file systems allow you to - change the owner if you are currently the owner. When you - access a remote file system, the behavior you encounter is - determined by the system that actually holds the file, not by - the system your program is running on. + `FTW_SL' + The item is a symbolic link. Since symbolic links are + normally followed seeing this value in a `ftw' callback + function means the referenced file does not exist. The + situation for `nftw' is different. - *Note Options for Files::, for information about the - `_POSIX_CHOWN_RESTRICTED' macro. + This value is only available if the program is compiled with + `_BSD_SOURCE' or `_XOPEN_EXTENDED' defined before including + the first header.

However for the third argument some additional values are + defined to allow finer differentiation: + `FTW_DP' + The current item is a directory and all subdirectories have + already been visited and reported. This flag is returned + instead of `FTW_D' if the `FTW_DEPTH' flag is passed to + `nftw' (see below). - `EROFS' - The file resides on a read-only file system. + `FTW_SLN' + The current item is a stale symbolic link.

Usually 0200. - `S_IWRITE' is an obsolete synonym provided for BSD compatibility. + `int base' + The value is the offset into the string passed in the first + parameter to the callback function of the beginning of the + file name. The rest of the string is the path of the file. + This information is especially important if the `FTW_CHDIR' + flag was set in calling `nftw' since then the current + directory is the one the current item is found in. -`S_IXUSR' -`S_IEXEC' - Execute (for ordinary files) or search (for directories) - permission bit for the owner of the file. Usually 0100. - `S_IEXEC' is an obsolete synonym provided for BSD compatibility. + `int level' + Whilst processing, the code tracks how many directories down + it has gone to find the current file. This nesting level + starts at 0 for files in the initial directory (or is zero + for the initial file if a file was passed). -`S_IRWXU' - This is equivalent to `(S_IRUSR | S_IWUSR | S_IXUSR)'. + - Function: int ftw (const char *FILENAME, __ftw_func_t FUNC, int + DESCRIPTORS) + The `ftw' function calls the callback function given in the + parameter FUNC for every item which is found in the directory + specified by FILENAME and all directories below. The function + follows symbolic links if necessary but does not process an item + twice. If FILENAME is not a directory then it itself is the only + object returned to the callback function. -`S_IRGRP' - Read permission bit for the group owner of the file. Usually 040. + The file name passed to the callback function is constructed by + taking the FILENAME parameter and appending the names of all passed + directories and then the local file name. So the callback + function can use this parameter to access the file. `ftw' also + calls `stat' for the file and passes that information on to the + callback function. If this `stat' call was not successful the + failure is indicated by setting the third argument of the callback + function to `FTW_NS'. Otherwise it is set according to the + description given in the account of `__ftw_func_t' above. -`S_IWGRP' - Write permission bit for the group owner of the file. Usually 020. + The callback function is expected to return 0 to indicate that no + error occurred and that processing should continue. If an error + occurred in the callback function or it wants `ftw' to return + immediately, the callback function can return a value other than + 0. This is the only correct way to stop the function. The + program must not use `setjmp' or similar techniques to continue + from another place. This would leave resources allocated by the + `ftw' function unfreed. -`S_IXGRP' - Execute or search permission bit for the group owner of the file. - Usually 010. + The DESCRIPTORS parameter to `ftw' specifies how many file + descriptors it is allowed to consume.

At most DESCRIPTORS file descriptors are + consumed during the `nftw' call. -`S_ISUID' - This is the set-user-ID on execute bit, usually 04000. *Note How - Change Persona::. + One difference is that the callback function is of a different + type. It is of type `struct FTW *' and provides the callback + function with the extra information described above. -`S_ISGID' - This is the set-group-ID on execute bit, usually 02000. *Note How - Change Persona::. + A second difference is that `nftw' takes a fourth argument, which + is 0 or a bitwise-OR combination of any of the following values. -`S_ISVTX' - This is the "sticky" bit, usually 01000. + `FTW_PHYS' + While traversing the directory symbolic links are not + followed. Instead symbolic links are reported using the + `FTW_SL' value for the type parameter to the callback + function. If the file referenced by a symbolic link does not + exist `FTW_SLN' is returned instead. - For a directory it gives permission to delete a file in that - directory only if you own that file. Ordinarily, a user can - either delete all the files in a directory or cannot delete any of - them (based on whether the user has write permission for the - directory). The same restriction applies--you must have both - write permission for the directory and own the file you want to - delete. The one exception is that the owner of the directory can - delete any file in the directory, no matter who owns it (provided - the owner has given himself write permission for the directory). - This is commonly used for the `/tmp' directory, where anyone may - create files but not delete files created by other users. + `FTW_MOUNT' + The callback function is only called for items which are on + the same mounted filesystem as the directory given by the + FILENAME parameter to `nftw'. - Originally the sticky bit on an executable file modified the - swapping policies of the system. Normally, when a program - terminated, its pages in core were immediately freed and reused. - If the sticky bit was set on the executable file, the system kept - the pages in core for a while as if the program were still - running. This was advantageous for a program likely to be run - many times in succession. This usage is obsolete in modern - systems. When a program terminates, its pages always remain in - core as long as there is no shortage of memory in the system. - When the program is next run, its pages will still be in core if - no shortage arose since the last run. + `FTW_CHDIR' + If this flag is given the current working directory is + changed to the directory of the reported object before the + callback function is called. When `ntfw' finally returns the + current directory is restored to its original value. - On some modern systems where the sticky bit has no useful meaning - for an executable file, you cannot set the bit at all for a - non-directory. If you try, `chmod' fails with `EFTYPE'; *note - Setting Permissions::. + `FTW_DEPTH' + If this option is specified then all subdirectories and files + within them are processed before processing the top directory + itself (depth-first processing). This also means the type + flag given to the callback function is `FTW_DP' and not + `FTW_D'. - Some systems (particularly SunOS) have yet another use for the - sticky bit. If the sticky bit is set on a file that is _not_ - executable, it means the opposite: never cache the pages of this - file at all. The main use of this is for the files on an NFS - server machine which are used as the swap area of diskless client - machines. The idea is that the pages of the file will be cached - in the client's memory, so it is a waste of the server's memory to - cache them a second time. With this usage the sticky bit also - implies that the filesystem may fail to record the file's - modification time onto disk reliably (the idea being that no-one - cares for a swap file). + The return value is computed in the same way as for `ftw'. `nftw' + returns 0 if no failures occurred and all callback functions + returned 0. In case of internal errors, such as memory problems, + the return value is -1 and ERRNO is set accordingly. If the + return value of a callback invocation was non-zero then that value + is returned. - This bit is only available on BSD systems (and those derived from - them). Therefore one has to use the `_BSD_SOURCE' feature select - macro to get the definition (*note Feature Test Macros::). + When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32-bit system this function is in fact `nftw64', i.e. the LFS + interface transparently replaces the old interface. - The actual bit values of the symbols are listed in the table above -so you can decode file mode values when debugging your programs. These -bit values are correct for most systems, but they are not guaranteed. + - Function: int nftw64 (const char *FILENAME, __nftw64_func_t FUNC, + int DESCRIPTORS, int FLAG) + This function is similar to `nftw' but it can work on filesystems + with large files. File information is reported using a variable + of type `struct stat64' which is passed by reference to the + callback function. - *Warning:* Writing explicit numbers for file permissions is bad -practice. Not only is it not portable, it also requires everyone who -reads your program to remember what the bits mean. To make your program -clean use the symbolic names. + When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32-bit system this function is available under the name `nftw' and + transparently replaces the old implementation.  -File: libc.info, Node: Access Permission, Next: Setting Permissions, Prev: Permission Bits, Up: File Attributes - -How Your Access to a File is Decided ------------------------------------- - - Recall that the operating system normally decides access permission -for a file based on the effective user and group IDs of the process and -its supplementary group IDs, together with the file's owner, group and -permission bits. These concepts are discussed in detail in *Note -Process Persona::. - - If the effective user ID of the process matches the owner user ID of -the file, then permissions for read, write, and execute/search are -controlled by the corresponding "user" (or "owner") bits. Likewise, if -any of the effective group ID or supplementary group IDs of the process -matches the group owner ID of the file, then permissions are controlled -by the "group" bits. Otherwise, permissions are controlled by the -"other" bits. +File: libc.info, Node: Hard Links, Next: Symbolic Links, Prev: Working with Directory Trees, Up: File System Interface - Privileged users, like `root', can access any file regardless of its -permission bits. As a special case, for a file to be executable even -by a privileged user, at least one of its execute bits must be set. +Hard Links +========== - -File: libc.info, Node: Setting Permissions, Next: Testing File Access, Prev: Access Permission, Up: File Attributes + In POSIX systems, one file can have many names at the same time. +All of the names are equally real, and no one of them is preferred to +the others. -Assigning File Permissions --------------------------- + To add a name to a file, use the `link' function. (The new name is +also called a "hard link" to the file.) Creating a new link to a file +does not copy the contents of the file; it simply makes a new name by +which the file can be known, in addition to the file's existing name or +names. - The primitive functions for creating files (for example, `open' or -`mkdir') take a MODE argument, which specifies the file permissions to -give the newly created file. This mode is modified by the process's -"file creation mask", or "umask", before it is used. + One file can have names in several directories, so the organization +of the file system is not a strict hierarchy or tree. - The bits that are set in the file creation mask identify permissions -that are always to be disabled for newly created files. For example, if -you set all the "other" access bits in the mask, then newly created -files are not accessible at all to processes in the "other" category, -even if the MODE argument passed to the create function would permit -such access. In other words, the file creation mask is the complement -of the ordinary access permissions you want to grant. + In most implementations, it is not possible to have hard links to the +same file in multiple file systems. `link' reports an error if you try +to make a hard link to the file from another file system when this +cannot be done. - Programs that create files typically specify a MODE argument that -includes all the permissions that make sense for the particular file. -For an ordinary file, this is typically read and write permission for -all classes of users. These permissions are then restricted as -specified by the individual user's own file creation mask. + The prototype for the `link' function is declared in the header file +`unistd.h'. - To change the permission of an existing file given its name, call -`chmod'. This function uses the specified permission bits and ignores -the file creation mask. + - Function: int link (const char *OLDNAME, const char *NEWNAME) + The `link' function makes a new link to the existing file named by + OLDNAME, under the new name NEWNAME. - In normal use, the file creation mask is initialized by the user's -login shell (using the `umask' shell command), and inherited by all -subprocesses. Application programs normally don't need to worry about -the file creation mask. It will automatically do what it is supposed to -do. + This function returns a value of `0' if it is successful and `-1' + on failure. In addition to the usual file name errors (*note File + Name Errors::) for both OLDNAME and NEWNAME, the following `errno' + error conditions are defined for this function: - When your program needs to create a file and bypass the umask for its -access permissions, the easiest way to do this is to use `fchmod' after -opening the file, rather than changing the umask. In fact, changing -the umask is usually done only by shells. They use the `umask' -function. + `EACCES' + You are not allowed to write to the directory in which the + new link is to be written. - The functions in this section are declared in `sys/stat.h'. + `EEXIST' + There is already a file named NEWNAME. If you want to replace + this link with a new link, you must remove the old link + explicitly first. - - Function: mode_t umask (mode_t MASK) - The `umask' function sets the file creation mask of the current - process to MASK, and returns the previous value of the file - creation mask. + `EMLINK' + There are already too many links to the file named by OLDNAME. + (The maximum number of links to a file is `LINK_MAX'; see + *Note Limits for Files::.) - Here is an example showing how to read the mask with `umask' - without changing it permanently: + `ENOENT' + The file named by OLDNAME doesn't exist. You can't make a + link to a file that doesn't exist. - mode_t - read_umask (void) - { - mode_t mask = umask (0); - umask (mask); - return mask; - } + `ENOSPC' + The directory or file system that would contain the new link + is full and cannot be extended. - However, it is better to use `getumask' if you just want to read - the mask value, because it is reentrant (at least if you use the - GNU operating system). + `EPERM' + In the GNU system and some others, you cannot make links to + directories. Many systems allow only privileged users to do + so. This error is used to report the problem. - - Function: mode_t getumask (void) - Return the current value of the file creation mask for the current - process. This function is a GNU extension. + `EROFS' + The directory containing the new link can't be modified + because it's on a read-only file system. - - Function: int chmod (const char *FILENAME, mode_t MODE) - The `chmod' function sets the access permission bits for the file - named by FILENAME to MODE. + `EXDEV' + The directory specified in NEWNAME is on a different file + system than the existing file. - If FILENAME is a symbolic link, `chmod' changes the permissions of - the file pointed to by the link, not those of the link itself. + `EIO' + A hardware error occurred while trying to read or write the + to filesystem. - This function returns `0' if successful and `-1' if not. In - addition to the usual file name errors (*note File Name Errors::), - the following `errno' error conditions are defined for this - function: + +File: libc.info, Node: Symbolic Links, Next: Deleting Files, Prev: Hard Links, Up: File System Interface - `ENOENT' - The named file doesn't exist. +Symbolic Links +============== - `EPERM' - This process does not have permission to change the access - permissions of this file. Only the file's owner (as judged - by the effective user ID of the process) or a privileged user - can change them. + The GNU system supports "soft links" or "symbolic links". This is a +kind of "file" that is essentially a pointer to another file name. +Unlike hard links, symbolic links can be made to directories or across +file systems with no restrictions. You can also make a symbolic link +to a name which is not the name of any file. (Opening this link will +fail until a file by that name is created.) Likewise, if the symbolic +link points to an existing file which is later deleted, the symbolic +link continues to point to the same file name even though the name no +longer names any file. - `EROFS' - The file resides on a read-only file system. + The reason symbolic links work the way they do is that special things +happen when you try to open the link. The `open' function realizes you +have specified the name of a link, reads the file name contained in the +link, and opens that file name instead. The `stat' function likewise +operates on the file that the symbolic link points to, instead of on +the link itself. - `EFTYPE' - MODE has the `S_ISVTX' bit (the "sticky bit") set, and the - named file is not a directory. Some systems do not allow - setting the sticky bit on non-directory files, and some do - (and only some of those assign a useful meaning to the bit - for non-directory files). + By contrast, other operations such as deleting or renaming the file +operate on the link itself. The functions `readlink' and `lstat' also +refrain from following symbolic links, because their purpose is to +obtain information about the link. `link', the function that makes a +hard link, does too. It makes a hard link to the symbolic link, which +one rarely wants. - You only get `EFTYPE' on systems where the sticky bit has no - useful meaning for non-directory files, so it is always safe - to just clear the bit in MODE and call `chmod' again. *Note - Permission Bits::, for full details on the sticky bit. + Some systems have for some functions operating on files have a limit +on how many symbolic links are followed when resolving a path name. The +limit if it exists is published in the `sys/param.h' header file. - - Function: int fchmod (int FILEDES, int MODE) - This is like `chmod', except that it changes the permissions of the - currently open file given by FILEDES. + - Macro: int MAXSYMLINKS + The macro `MAXSYMLINKS' specifies how many symlinks some function + will follow before returning `ELOOP'. Not all functions behave the + same and this value is not the same a that returned for + `_SC_SYMLOOP' by `sysconf'. In fact, the `sysconf' result can + indicate that there is no fixed limit although `MAXSYMLINKS' + exists and has a finite value. - The return value from `fchmod' is `0' on success and `-1' on - failure. The following `errno' error codes are defined for this - function: + Prototypes for most of the functions listed in this section are in +`unistd.h'. - `EBADF' - The FILEDES argument is not a valid file descriptor. + - Function: int symlink (const char *OLDNAME, const char *NEWNAME) + The `symlink' function makes a symbolic link to OLDNAME named + NEWNAME. - `EINVAL' - The FILEDES argument corresponds to a pipe or socket, or - something else that doesn't really have access permissions. + The normal return value from `symlink' is `0'. A return value of + `-1' indicates an error. In addition to the usual file name + syntax errors (*note File Name Errors::), the following `errno' + error conditions are defined for this function: - `EPERM' - This process does not have permission to change the access - permissions of this file. Only the file's owner (as judged - by the effective user ID of the process) or a privileged user - can change them. + `EEXIST' + There is already an existing file named NEWNAME. `EROFS' - The file resides on a read-only file system. + The file NEWNAME would exist on a read-only file system. - -File: libc.info, Node: Testing File Access, Next: File Times, Prev: Setting Permissions, Up: File Attributes + `ENOSPC' + The directory or file system cannot be extended to make the + new link. -Testing Permission to Access a File ------------------------------------ + `EIO' + A hardware error occurred while reading or writing data on + the disk. - In some situations it is desirable to allow programs to access files -or devices even if this is not possible with the permissions granted to -the user. One possible solution is to set the setuid-bit of the program -file. If such a program is started the _effective_ user ID of the -process is changed to that of the owner of the program file. So to -allow write access to files like `/etc/passwd', which normally can be -written only by the super-user, the modifying program will have to be -owned by `root' and the setuid-bit must be set. - But beside the files the program is intended to change the user -should not be allowed to access any file to which s/he would not have -access anyway. The program therefore must explicitly check whether _the -user_ would have the necessary access to a file, before it reads or -writes the file. + - Function: int readlink (const char *FILENAME, char *BUFFER, size_t + SIZE) + The `readlink' function gets the value of the symbolic link + FILENAME. The file name that the link points to is copied into + BUFFER. This file name string is _not_ null-terminated; + `readlink' normally returns the number of characters copied. The + SIZE argument specifies the maximum number of characters to copy, + usually the allocation size of BUFFER. - To do this, use the function `access', which checks for access -permission based on the process's _real_ user ID rather than the -effective user ID. (The setuid feature does not alter the real user ID, -so it reflects the user who actually ran the program.) + If the return value equals SIZE, you cannot tell whether or not + there was room to return the entire name. So make a bigger buffer + and call `readlink' again. Here is an example: - There is another way you could check this access, which is easy to -describe, but very hard to use. This is to examine the file mode bits -and mimic the system's own access computation. This method is -undesirable because many systems have additional access control -features; your program cannot portably mimic them, and you would not -want to try to keep track of the diverse features that different systems -have. Using `access' is simple and automatically does whatever is -appropriate for the system you are using. + char * + readlink_malloc (const char *filename) + { + int size = 100; + + while (1) + { + char *buffer = (char *) xmalloc (size); + int nchars = readlink (filename, buffer, size); + if (nchars < 0) + return NULL; + if (nchars < size) + return buffer; + free (buffer); + size *= 2; + } + } - `access' is _only_ only appropriate to use in setuid programs. A -non-setuid program will always use the effective ID rather than the -real ID. + A value of `-1' is returned in case of error. In addition to the + usual file name errors (*note File Name Errors::), the following + `errno' error conditions are defined for this function: - The symbols in this section are declared in `unistd.h'. + `EINVAL' + The named file is not a symbolic link. - - Function: int access (const char *FILENAME, int HOW) - The `access' function checks to see whether the file named by - FILENAME can be accessed in the way specified by the HOW argument. - The HOW argument either can be the bitwise OR of the flags - `R_OK', `W_OK', `X_OK', or the existence test `F_OK'. + `EIO' + A hardware error occurred while reading or writing data on + the disk. - This function uses the _real_ user and group IDs of the calling - process, rather than the _effective_ IDs, to check for access - permission. As a result, if you use the function from a `setuid' - or `setgid' program (*note How Change Persona::), it gives - information relative to the user who actually ran the program. + In some situations it is desirable to resolve all the to get the real +name of a file where no prefix names a symbolic link which is followed +and no filename in the path is `.' or `..'. This is for instance +desirable if files have to be compare in which case different names can +refer to the same inode. - The return value is `0' if the access is permitted, and `-1' - otherwise. (In other words, treated as a predicate function, - `access' returns true if the requested access is _denied_.) + - Function: char * canonicalize_file_name (const char *NAME) + The `canonicalize_file_name' function returns the absolute name of + the file named by NAME which contains no `.', `..' components nor + any repeated path separators (`/') or symlinks. The result is + passed back as the return value of the function in a block of + memory allocated with `malloc'. If the result is not used anymore + the memory should be freed with a call to `free'. - In addition to the usual file name errors (*note File Name - Errors::), the following `errno' error conditions are defined for - this function: + In any of the path components except the last one is missing the + function returns a NULL pointer. This is also what is returned if + the length of the path reaches or exceeds `PATH_MAX' characters. + In any case `errno' is set accordingly. + + `ENAMETOOLONG' + The resulting path is too long. This error only occurs on + systems which have a limit on the file name length. `EACCES' - The access specified by HOW is denied. + At least one of the path components is not readable. `ENOENT' - The file doesn't exist. + The input file name is empty. - `EROFS' - Write permission was requested for a file on a read-only file - system. + `ENOENT' + At least one of the path components does not exist. - These macros are defined in the header file `unistd.h' for use as -the HOW argument to the `access' function.

For example, + you might see this error if the file name specifies the root + directory or a mount point for a file system. `ENOENT' - The file doesn't exist. + The file name to be deleted doesn't exist. `EPERM' - If the TIMES argument is not a null pointer, you must either - be the owner of the file or be a privileged user. + On some systems `unlink' cannot be used to delete the name of + a directory, or at least can only be used this way by a + privileged user. To avoid such problems, use `rmdir' to + delete directories. (In the GNU system `unlink' can never + delete the name of a directory.) `EROFS' - The file lives on a read-only file system. + The directory containing the file name to be deleted is on a + read-only file system and can't be modified. - Each of the three time stamps has a corresponding microsecond part, -which extends its resolution. These fields are called `st_atime_usec', -`st_mtime_usec', and `st_ctime_usec'; each has a value between 0 and -999,999, which indicates the time in microseconds. They correspond to -the `tv_usec' field of a `timeval' structure; see *Note High-Resolution -Calendar::. + - Function: int rmdir (const char *FILENAME) + The `rmdir' function deletes a directory. The directory must be + empty before it can be removed; in other words, it can only contain + entries for `.' and `..'. - The `utimes' function is like `utime', but also lets you specify the -fractional part of the file times. The prototype for this function is -in the header file `sys/time.h'. + In most other respects, `rmdir' behaves like `unlink'. There are + two additional `errno' error conditions defined for `rmdir': - - Function: int utimes (const char *FILENAME, struct timeval TVP[2]) - This function sets the file access and modification times of the - file FILENAME. The new file access time is specified by `TVP[0]', - and the new modification time by `TVP[1]'. This function comes - from BSD. + `ENOTEMPTY' + `EEXIST' + The directory to be deleted is not empty. - The return values and error conditions are the same as for the - `utime' function. + These two error codes are synonymous; some systems use one, and + some use the other. The GNU system always uses `ENOTEMPTY'. + + The prototype for this function is declared in the header file + `unistd.h'. + + - Function: int remove (const char *FILENAME) + This is the ISO C function to remove a file. It works like + `unlink' for files and like `rmdir' for directories. `remove' is + declared in `stdio.h'.  -File: libc.info, Node: File Size, Prev: File Times, Up: File Attributes +File: libc.info, Node: Renaming Files, Next: Creating Directories, Prev: Deleting Files, Up: File System Interface -File Size ---------- +Renaming Files +============== - Normally file sizes are maintained automatically. A file begins -with a size of 0 and is automatically extended when data is written past -its end. It is also possible to empty a file completely by an `open' -or `fopen' call. + The `rename' function is used to change a file's name. - However, sometimes it is necessary to _reduce_ the size of a file. -This can be done with the `truncate' and `ftruncate' functions. They -were introduced in BSD Unix. `ftruncate' was later added to POSIX.1. + - Function: int rename (const char *OLDNAME, const char *NEWNAME) + The `rename' function renames the file OLDNAME to NEWNAME. The + file formerly accessible under the name OLDNAME is afterwards + accessible as NEWNAME instead. (If the file had any other names + aside from OLDNAME, it continues to have those names.) - Some systems allow you to extend a file (creating holes) with these -functions. This is useful when using memory-mapped I/O (*note -Memory-mapped I/O::), where files are not automatically extended. -However, it is not portable but must be implemented if `mmap' allows -mapping of files (i.e., `_POSIX_MAPPED_FILES' is defined). + The directory containing the name NEWNAME must be on the same file + system as the directory containing the name OLDNAME. - Using these functions on anything other than a regular file gives -_undefined_ results. On many systems, such a call will appear to -succeed, without actually accomplishing anything. + One special case for `rename' is when OLDNAME and NEWNAME are two + names for the same file. The consistent way to handle this case + is to delete OLDNAME. However, in this case POSIX requires that + `rename' do nothing and report success--which is inconsistent. We + don't know what your operating system will do. - - Function: int truncate (const char *FILENAME, off_t LENGTH) - The `truncate' function changes the size of FILENAME to LENGTH. - If LENGTH is shorter than the previous length, data at the end - will be lost. The file must be writable by the user to perform - this operation. + If OLDNAME is not a directory, then any existing file named + NEWNAME is removed during the renaming operation. However, if + NEWNAME is the name of a directory, `rename' fails in this case. - If LENGTH is longer, holes will be added to the end. However, some - systems do not support this feature and will leave the file - unchanged. + If OLDNAME is a directory, then either NEWNAME must not exist or + it must name a directory that is empty. In the latter case, the + existing directory named NEWNAME is deleted first. The name + NEWNAME must not specify a subdirectory of the directory `oldname' + which is being renamed. - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `truncate' function is in fact `truncate64' and the type `off_t' - has 64 bits which makes it possible to handle files up to 2^63 - bytes in length. + One useful feature of `rename' is that the meaning of NEWNAME + changes "atomically" from any previously existing file by that + name to its new meaning (i.e. the file that was called OLDNAME). + There is no instant at which NEWNAME is non-existent "in between" + the old meaning and the new meaning. If there is a system crash + during the operation, it is possible for both names to still + exist; but NEWNAME will always be intact if it exists at all. - The return value is 0 for success, or -1 for an error. In - addition to the usual file name errors, the following errors may - occur: + If `rename' fails, it returns `-1'. In addition to the usual file + name errors (*note File Name Errors::), the following `errno' + error conditions are defined for this function: `EACCES' - The file is a directory or not writable. + One of the directories containing NEWNAME or OLDNAME refuses + write permission; or NEWNAME and OLDNAME are directories and + write permission is refused for one of them. - `EINVAL' - LENGTH is negative. + `EBUSY' + A directory named by OLDNAME or NEWNAME is being used by the + system in a way that prevents the renaming from working. + This includes directories that are mount points for + filesystems, and directories that are the current working + directories of processes. - `EFBIG' - The operation would extend the file beyond the limits of the - operating system. + `ENOTEMPTY' + `EEXIST' + The directory NEWNAME isn't empty. The GNU system always + returns `ENOTEMPTY' for this, but some other systems return + `EEXIST'. - `EIO' - A hardware I/O error occurred. + `EINVAL' + OLDNAME is a directory that contains NEWNAME. - `EPERM' - The file is "append-only" or "immutable". + `EISDIR' + NEWNAME is a directory but the OLDNAME isn't. - `EINTR' - The operation was interrupted by a signal. + `EMLINK' + The parent directory of NEWNAME would have too many links + (entries). + `ENOENT' + The file OLDNAME doesn't exist. - - Function: int truncate64 (const char *NAME, off64_t LENGTH) - This function is similar to the `truncate' function. The - difference is that the LENGTH argument is 64 bits wide even on 32 - bits machines, which allows the handling of files with sizes up to - 2^63 bytes. + `ENOSPC' + The directory that would contain NEWNAME has no room for + another entry, and there is no space left in the file system + to expand it. - When the source file is compiled with `_FILE_OFFSET_BITS == 64' on - a 32 bits machine this function is actually available under the - name `truncate' and so transparently replaces the 32 bits - interface. + `EROFS' + The operation would involve writing to a directory on a + read-only file system. - - Function: int ftruncate (int FD, off_t LENGTH) - This is like `truncate', but it works on a file descriptor FD for - an opened file instead of a file name to identify the object. The - file must be opened for writing to successfully carry out the - operation. + `EXDEV' + The two file names NEWNAME and OLDNAME are on different file + systems. - The POSIX standard leaves it implementation defined what happens - if the specified new LENGTH of the file is bigger than the - original size. The `ftruncate' function might simply leave the - file alone and do nothing or it can increase the size to the - desired size. In this later case the extended area should be - zero-filled. So using `ftruncate' is no reliable way to increase - the file size but if it is possible it is probably the fastest - way. The function also operates on POSIX shared memory segments - if these are implemented by the system. + +File: libc.info, Node: Creating Directories, Next: File Attributes, Prev: Renaming Files, Up: File System Interface - `ftruncate' is especially useful in combination with `mmap'. - Since the mapped region must have a fixed size one cannot enlarge - the file by writing something beyond the last mapped page. - Instead one has to enlarge the file itself and then remap the file - with the new size. The example below shows how this works. +Creating Directories +==================== - When the source file is compiled with `_FILE_OFFSET_BITS == 64' the - `ftruncate' function is in fact `ftruncate64' and the type `off_t' - has 64 bits which makes it possible to handle files up to 2^63 - bytes in length. + Directories are created with the `mkdir' function. (There is also a +shell command `mkdir' which does the same thing.) - The return value is 0 for success, or -1 for an error. The - following errors may occur: + - Function: int mkdir (const char *FILENAME, mode_t MODE) + The `mkdir' function creates a new, empty directory with name + FILENAME. - `EBADF' - FD does not correspond to an open file. + The argument MODE specifies the file permissions for the new + directory file. *Note Permission Bits::, for more information + about this. + + A return value of `0' indicates successful completion, and `-1' + indicates failure. In addition to the usual file name syntax + errors (*note File Name Errors::), the following `errno' error + conditions are defined for this function: `EACCES' - FD is a directory or not open for writing. + Write permission is denied for the parent directory in which + the new directory is to be added. - `EINVAL' - LENGTH is negative. + `EEXIST' + A file named FILENAME already exists. - `EFBIG' - The operation would extend the file beyond the limits of the - operating system. + `EMLINK' + The parent directory has too many links (entries). - `EIO' - A hardware I/O error occurred. + Well-designed file systems never report this error, because + they permit more links than your disk could possibly hold. + However, you must still take account of the possibility of + this error, as it could result from network access to a file + system on another machine. - `EPERM' - The file is "append-only" or "immutable". + `ENOSPC' + The file system doesn't have enough room to create the new + directory. - `EINTR' - The operation was interrupted by a signal. + `EROFS' + The parent directory of the directory being created is on a + read-only file system and cannot be modified. + To use this function, your program should include the header file + `sys/stat.h'. - - Function: int ftruncate64 (int ID, off64_t LENGTH) - This function is similar to the `ftruncate' function.

If the current size of the file is too small it is -extended. Note the it is extended by a round number of pages. This is -a requirement of `mmap'.

The GNU library includes this -function for compatibility with BSD. + When you read the attributes of a file, they come back in a structure +called `struct stat'. This section describes the names of the +attributes, their data types, and what they mean.

The - MODE specifies the mode of the file, and may include the various - special file bits, such as `S_IFCHR' (for a character special file) - or `S_IFBLK' (for a block special file). *Note Testing File - Type::. + - Data Type: struct stat + The `stat' structure type is used to return information about the + attributes of a file. It contains at least the following members: - The DEV argument specifies which device the special file refers to. - Its exact interpretation depends on the kind of special file being - created. + `mode_t st_mode' + Specifies the mode of the file. This includes file type + information (*note Testing File Type::) and the file + permission bits (*note Permission Bits::). - The return value is `0' on success and `-1' on error. In addition - to the usual file name errors (*note File Name Errors::), the - following `errno' error conditions are defined for this function: + `ino_t st_ino' + The file serial number, which distinguishes this file from + all other files on the same device. - `EPERM' - The calling process is not privileged. Only the superuser - can create special files. + `dev_t st_dev' + Identifies the device containing the file. The `st_ino' and + `st_dev', taken together, uniquely identify the file. The + `st_dev' value is not necessarily consistent across reboots or + system crashes, however. - `ENOSPC' - The directory or file system that would contain the new file - is full and cannot be extended. + `nlink_t st_nlink' + The number of hard links to the file. This count keeps track + of how many directories have entries for this file. If the + count is ever decremented to zero, then the file itself is + discarded as soon as no process still holds it open. + Symbolic links are not counted in the total. - `EROFS' - The directory containing the new file can't be modified - because it's on a read-only file system. + `uid_t st_uid' + The user ID of the file's owner. *Note File Owner::. - `EEXIST' - There is already a file named FILENAME.

Or you can use the `tmpnam' (better: -`tmpnam_r') function to provide a name for a temporary file and then -you can open it in the usual way with `fopen'. + `unsigned long int st_atime_usec' + This is the fractional part of the last access time for the + file. *Note File Times::. - The `tempnam' function is like `tmpnam' but lets you choose what -directory temporary files will go in, and something about what their -file names will look like. Important for multi-threaded programs is -that `tempnam' is reentrant, while `tmpnam' is not since it returns a -pointer to a static buffer. + `time_t st_mtime' + This is the time of the last modification to the contents of + the file. *Note File Times::. - These facilities are declared in the header file `stdio.h'. + `unsigned long int st_mtime_usec' + This is the fractional part of the time of the last + modification to the contents of the file. *Note File Times::. - - Function: FILE * tmpfile (void) - This function creates a temporary binary file for update mode, as - if by calling `fopen' with mode `"wb+"'. The file is deleted - automatically when it is closed or when the program terminates. - (On some other ISO C systems the file may fail to be deleted if - the program terminates abnormally). + `time_t st_ctime' + This is the time of the last modification to the attributes + of the file. *Note File Times::. - This function is reentrant. + `unsigned long int st_ctime_usec' + This is the fractional part of the time of the last + modification to the attributes of the file. *Note File + Times::. - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `tmpfile64', i.e. the LFS - interface transparently replaces the old interface. + `blkcnt_t st_blocks' + This is the amount of disk space that the file occupies, + measured in units of 512-byte blocks. - - Function: FILE * tmpfile64 (void) - This function is similar to `tmpfile', but the stream it returns a - pointer to was opened using `tmpfile64'. Therefore this stream can - be used for files larger then 2^31 bytes on 32-bit machines. + The number of disk blocks is not strictly proportional to the + size of the file, for two reasons: the file system may use + some blocks for internal record keeping; and the file may be + sparse--it may have "holes" which contain zeros but do not + actually take up space on the disk. - Please note that the return type is still `FILE *'. There is no - special `FILE' type for the LFS interface. + You can tell (approximately) whether a file is sparse by + comparing this value with `st_size', like this: - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 - bits machine this function is available under the name `tmpfile' - and so transparently replaces the old interface. + (st.st_blocks * 512 < st.st_size) - - Function: char * tmpnam (char *RESULT) - This function constructs and returns a valid file name that does - not refer to any existing file. If the RESULT argument is a null - pointer, the return value is a pointer to an internal static - string, which might be modified by subsequent calls and therefore - makes this function non-reentrant. Otherwise, the RESULT argument - should be a pointer to an array of at least `L_tmpnam' characters, - and the result is written into that array. + This test is not perfect because a file that is just slightly + sparse might not be detected as sparse at all. For practical + applications, this is not a problem. - It is possible for `tmpnam' to fail if you call it too many times - without removing previously-created files. This is because the - limited length of the temporary file names gives room for only a - finite number of different names. If `tmpnam' fails it returns a - null pointer. + `unsigned int st_blksize' + The optimal block size for reading of writing this file, in + bytes. You might use this size for allocating the buffer + space for reading of writing the file. (This is unrelated to + `st_blocks'.) - *Warning:* Between the time the pathname is constructed and the - file is created another process might have created a file with the - same name using `tmpnam', leading to a possible security hole. The - implementation generates names which can hardly be predicted, but - when opening the file you should use the `O_EXCL' flag. Using - `tmpfile' or `mkstemp' is a safe way to avoid this problem. + The extensions for the Large File Support (LFS) require, even on +32-bit machines, types which can handle file sizes up to 2^63. +Therefore a new definition of `struct stat' is necessary. - - Function: char * tmpnam_r (char *RESULT) - This function is nearly identical to the `tmpnam' function, except - that if RESULT is a null pointer it returns a null pointer. + - Data Type: struct stat64 + The members of this type are the same and have the same names as + those in `struct stat'. The only difference is that the members + `st_ino', `st_size', and `st_blocks' have a different type to + support larger values. - This guarantees reentrancy because the non-reentrant situation of - `tmpnam' cannot happen here. + `mode_t st_mode' + Specifies the mode of the file. This includes file type + information (*note Testing File Type::) and the file + permission bits (*note Permission Bits::). - *Warning*: This function has the same security problems as - `tmpnam'. + `ino64_t st_ino' + The file serial number, which distinguishes this file from + all other files on the same device. - - Macro: int L_tmpnam - The value of this macro is an integer constant expression that - represents the minimum size of a string large enough to hold a - file name generated by the `tmpnam' function. + `dev_t st_dev' + Identifies the device containing the file. The `st_ino' and + `st_dev', taken together, uniquely identify the file. The + `st_dev' value is not necessarily consistent across reboots or + system crashes, however. - - Macro: int TMP_MAX - The macro `TMP_MAX' is a lower bound for how many temporary names - you can create with `tmpnam'. You can rely on being able to call - `tmpnam' at least this many times before it might fail saying you - have made too many temporary file names. + `nlink_t st_nlink' + The number of hard links to the file. This count keeps track + of how many directories have entries for this file. If the + count is ever decremented to zero, then the file itself is + discarded as soon as no process still holds it open. + Symbolic links are not counted in the total. - With the GNU library, you can create a very large number of - temporary file names.

You might use this size for allocating the buffer + space for reading of writing the file. (This is unrelated to + `st_blocks'.) - Older Unix systems did not have the functions just described. -Instead they used `mktemp' and `mkstemp'. Both of these functions work -by modifying a file name template string you pass. The last six -characters of this string must be `XXXXXX'. These six `X's are -replaced with six characters which make the whole string a unique file -name. Usually the template string is something like -`/tmp/PREFIXXXXXXX', and each program uses a unique PREFIX. + Some of the file attributes have special data type names which exist +specifically for those attributes. (They are all aliases for well-known +integer types that you know and love.) These typedef names are defined +in the header file `sys/types.h' as well as in `sys/stat.h'. Here is a +list of them. - *Note:* Because `mktemp' and `mkstemp' modify the template string, -you _must not_ pass string constants to them.

In the + GNU system, this is equivalent to `unsigned int'. - - Function: char * mktemp (char *TEMPLATE) - The `mktemp' function generates a unique file name by modifying - TEMPLATE as described above. If successful, it returns TEMPLATE - as modified. If `mktemp' cannot find a unique file name, it makes - TEMPLATE an empty string and returns that. If TEMPLATE does not - end with `XXXXXX', `mktemp' returns a null pointer. + - Data Type: ino_t + This is an arithmetic data type used to represent file serial + numbers. (In Unix jargon, these are sometimes called "inode + numbers".) In the GNU system, this type is equivalent to + `unsigned long int'. - *Warning:* Between the time the pathname is constructed and the - file is created another process might have created a file with the - same name using `mktemp', leading to a possible security hole.

If successful, it modifies - TEMPLATE in place and returns a file descriptor for that file open - for reading and writing. If `mkstemp' cannot create a - uniquely-named file, it returns `-1'. If TEMPLATE does not end - with `XXXXXX', `mkstemp' returns `-1' and does not modify TEMPLATE. + - Data Type: ino64_t + This is an arithmetic data type used to represent file serial + numbers for the use in LFS. In the GNU system, this type is + equivalent to `unsigned long longint'. - The file is opened using mode `0600'.

One way of doing this is by using a -combination of `pipe' (to create the pipe), `fork' (to create the -subprocess), `dup2' (to force the subprocess to use the pipe as its -standard input or output channel), and `exec' (to execute the new -program). Or, you can use `popen' and `pclose'. + The "file mode", stored in the `st_mode' field of the file +attributes, contains two kinds of information: the file type code, and +the access permission bits. This section discusses only the type code, +which you can use to tell whether the file is a directory, socket, +symbolic link, and so on. For details about access permissions see +*Note Permission Bits::. - The advantage of using `popen' and `pclose' is that the interface is -much simpler and easier to use. But it doesn't offer as much -flexibility as using the low-level functions directly. + There are two ways you can access the file type information in a file +mode. Firstly, for each file type there is a "predicate macro" which +examines a given file mode and returns whether it is of that type or +not. Secondly, you can mask out the rest of the file mode to leave +just the file type code, and compare this against constants for each of +the supported file types. - - Function: FILE * popen (const char *COMMAND, const char *MODE) - The `popen' function is closely related to the `system' function; - see *Note Running a Command::. It executes the shell command - COMMAND as a subprocess. However, instead of waiting for the - command to complete, it creates a pipe to the subprocess and - returns a stream that corresponds to that pipe. + All of the symbols listed in this section are defined in the header +file `sys/stat.h'. - If you specify a MODE argument of `"r"', you can read from the - stream to retrieve data from the standard output channel of the - subprocess. The subprocess inherits its standard input channel - from the parent process. + The following predicate macros test the type of a file, given the +value M which is the `st_mode' field returned by `stat' on that file: - Similarly, if you specify a MODE argument of `"w"', you can write - to the stream to send data to the standard input channel of the - subprocess. The subprocess inherits its standard output channel - from the parent process. + - Macro: int S_ISDIR (mode_t M) + This macro returns non-zero if the file is a directory. - In the event of an error `popen' returns a null pointer. This - might happen if the pipe or stream cannot be created, if the - subprocess cannot be forked, or if the program cannot be executed. + - Macro: int S_ISCHR (mode_t M) + This macro returns non-zero if the file is a character special + file (a device like a terminal). - - Function: int pclose (FILE *STREAM) - The `pclose' function is used to close a stream created by `popen'. - It waits for the child process to terminate and returns its status - value, as for the `system' function. + - Macro: int S_ISBLK (mode_t M) + This macro returns non-zero if the file is a block special file (a + device like a disk). - Here is an example showing how to use `popen' and `pclose' to filter -output through another program, in this case the paging program `more'. + - Macro: int S_ISREG (mode_t M) + This macro returns non-zero if the file is a regular file. - #include - #include - - void - write_data (FILE * stream) - { - int i; - for (i = 0; i < 100; i++) - fprintf (stream, "%d\n", i); - if (ferror (stream)) - { - fprintf (stderr, "Output to stream failed.\n"); - exit (EXIT_FAILURE); - } - } - - int - main (void) - { - FILE *output; - - output = popen ("more", "w"); - if (!output) - { - fprintf (stderr, - "incorrect parameters or too many files.\n"); - return EXIT_FAILURE; - } - write_data (output); - if (pclose (output) != 0) - { - fprintf (stderr, - "Could not run more or other error.\n"); - } - return EXIT_SUCCESS; - } + - Macro: int S_ISFIFO (mode_t M) + This macro returns non-zero if the file is a FIFO special file, or + a pipe. *Note Pipes and FIFOs::. - -File: libc.info, Node: FIFO Special Files, Next: Pipe Atomicity, Prev: Pipe to a Subprocess, Up: Pipes and FIFOs + - Macro: int S_ISLNK (mode_t M) + This macro returns non-zero if the file is a symbolic link. *Note + Symbolic Links::. -FIFO Special Files -================== + - Macro: int S_ISSOCK (mode_t M) + This macro returns non-zero if the file is a socket. *Note + Sockets::. - A FIFO special file is similar to a pipe, except that it is created -in a different way.

The mode can be bitwise AND-ed with +`S_IFMT' to extract the file type code, and compared to the appropriate +constant. For example, - Once you have created a FIFO special file in this way, any process -can open it for reading or writing, in the same way as an ordinary file. -However, it has to be open at both ends simultaneously before you can -proceed to do any input or output operations on it.

The file's +group ID may be set to either the effective group ID of the process, or +the group ID of the directory that contains the file, depending on the +system where the file is stored. When you access a remote file system, +it behaves according to its own rules, not according to the system your +program is running on. Thus, your program must be prepared to encounter +either kind of behavior no matter what kind of system you run it on. -Socket Concepts -=============== + You can change the owner and/or group owner of an existing file using +the `chown' function. This is the primitive for the `chown' and +`chgrp' shell commands. - When you create a socket, you must specify the style of communication -you want to use and the type of protocol that should implement it. The -"communication style" of a socket defines the user-level semantics of -sending and receiving data on the socket. Choosing a communication -style specifies the answers to questions such as these: + The prototype for this function is declared in `unistd.h'. - * *What are the units of data transmission?* Some communication - styles regard the data as a sequence of bytes with no larger - structure; others group the bytes into records (which are known in - this context as "packets"). + - Function: int chown (const char *FILENAME, uid_t OWNER, gid_t GROUP) + The `chown' function changes the owner of the file FILENAME to + OWNER, and its group owner to GROUP. - * *Can data be lost during normal operation?* Some communication - styles guarantee that all the data sent arrives in the order it was - sent (barring system or network crashes); other styles occasionally - lose data as a normal part of operation, and may sometimes deliver - packets more than once or in the wrong order. + Changing the owner of the file on certain systems clears the + set-user-ID and set-group-ID permission bits. (This is because + those bits may not be appropriate for the new owner.) Other file + permission bits are not changed. - Designing a program to use unreliable communication styles usually - involves taking precautions to detect lost or misordered packets - and to retransmit data as needed. + The return value is `0' on success and `-1' on failure. In + addition to the usual file name errors (*note File Name Errors::), + the following `errno' error conditions are defined for this + function: - * *Is communication entirely with one partner?* Some communication - styles are like a telephone call--you make a "connection" with one - remote socket and then exchange data freely. Other styles are - like mailing letters--you specify a destination address for each - message you send. + `EPERM' + This process lacks permission to make the requested change. - You must also choose a "namespace" for naming the socket. A socket -name ("address") is meaningful only in the context of a particular -namespace. In fact, even the data type to use for a socket name may -depend on the namespace. Namespaces are also called "domains", but we -avoid that word as it can be confused with other usage of the same -term. Each namespace has a symbolic name that starts with `PF_'. A -corresponding symbolic name starting with `AF_' designates the address -format for that namespace. + Only privileged users or the file's owner can change the + file's group. On most file systems, only privileged users + can change the file owner; some file systems allow you to + change the owner if you are currently the owner. When you + access a remote file system, the behavior you encounter is + determined by the system that actually holds the file, not by + the system your program is running on. - Finally you must choose the "protocol" to carry out the -communication. The protocol determines what low-level mechanism is used -to transmit and receive data. Each protocol is valid for a particular -namespace and communication style; a namespace is sometimes called a -"protocol family" because of this, which is why the namespace names -start with `PF_'. + *Note Options for Files::, for information about the + `_POSIX_CHOWN_RESTRICTED' macro. - The rules of a protocol apply to the data passing between two -programs, perhaps on different computers; most of these rules are -handled by the operating system and you need not know about them. What -you do need to know about protocols is this: + `EROFS' + The file is on a read-only file system. - * In order to have communication between two sockets, they must - specify the _same_ protocol. + - Function: int fchown (int FILEDES, int OWNER, int GROUP) + This is like `chown', except that it changes the owner of the open + file with descriptor FILEDES. - * Each protocol is meaningful with particular style/namespace - combinations and cannot be used with inappropriate combinations. - For example, the TCP protocol fits only the byte stream style of - communication and the Internet namespace. + The return value from `fchown' is `0' on success and `-1' on + failure. The following `errno' error codes are defined for this + function: - * For each combination of style and namespace there is a "default - protocol", which you can request by specifying 0 as the protocol - number. And that's what you should normally do--use the default. + `EBADF' + The FILEDES argument is not a valid file descriptor. - Throughout the following description at various places -variables/parameters to denote sizes are required. And here the trouble -starts. In the first implementations the type of these variables was -simply `int'. On most machines at that time an `int' was 32 bits wide, -which created a _de facto_ standard requiring 32-bit variables. This -is important since references to variables of this type are passed to -the kernel. + `EINVAL' + The FILEDES argument corresponds to a pipe or socket, not an + ordinary file. - Then the POSIX people came and unified the interface with the words -"all size values are of type `size_t'".

Ordinarily, a user can + either delete all the files in a directory or cannot delete any of + them (based on whether the user has write permission for the + directory). The same restriction applies--you must have both + write permission for the directory and own the file you want to + delete. The one exception is that the owner of the directory can + delete any file in the directory, no matter who owns it (provided + the owner has given himself write permission for the directory). + This is commonly used for the `/tmp' directory, where anyone may + create files but not delete files created by other users. + + Originally the sticky bit on an executable file modified the + swapping policies of the system. Normally, when a program + terminated, its pages in core were immediately freed and reused. + If the sticky bit was set on the executable file, the system kept + the pages in core for a while as if the program were still + running. This was advantageous for a program likely to be run + many times in succession. This usage is obsolete in modern + systems. When a program terminates, its pages always remain in + core as long as there is no shortage of memory in the system. + When the program is next run, its pages will still be in core if + no shortage arose since the last run. + + On some modern systems where the sticky bit has no useful meaning + for an executable file, you cannot set the bit at all for a + non-directory. If you try, `chmod' fails with `EFTYPE'; *note + Setting Permissions::. + + Some systems (particularly SunOS) have yet another use for the + sticky bit. If the sticky bit is set on a file that is _not_ + executable, it means the opposite: never cache the pages of this + file at all. The main use of this is for the files on an NFS + server machine which are used as the swap area of diskless client + machines. The idea is that the pages of the file will be cached + in the client's memory, so it is a waste of the server's memory to + cache them a second time. With this usage the sticky bit also + implies that the filesystem may fail to record the file's + modification time onto disk reliably (the idea being that no-one + cares for a swap file). + + This bit is only available on BSD systems (and those derived from + them). Therefore one has to use the `_BSD_SOURCE' feature select + macro to get the definition (*note Feature Test Macros::). + + The actual bit values of the symbols are listed in the table above +so you can decode file mode values when debugging your programs. These +bit values are correct for most systems, but they are not guaranteed. + + *Warning:* Writing explicit numbers for file permissions is bad +practice.

You -can't use this data type effectively to interpret an address or -construct one; for that, you must use the proper data type for the -socket's namespace. + Recall that the operating system normally decides access permission +for a file based on the effective user and group IDs of the process and +its supplementary group IDs, together with the file's owner, group and +permission bits. These concepts are discussed in detail in *Note +Process Persona::. - Thus, the usual practice is to construct an address of the proper -namespace-specific type, then cast a pointer to `struct sockaddr *' -when you call `bind' or `getsockname'. + If the effective user ID of the process matches the owner user ID of +the file, then permissions for read, write, and execute/search are +controlled by the corresponding "user" (or "owner") bits. Likewise, if +any of the effective group ID or supplementary group IDs of the process +matches the group owner ID of the file, then permissions are controlled +by the "group" bits. Otherwise, permissions are controlled by the +"other" bits. - The one piece of information that you can get from the `struct -sockaddr' data type is the "address format designator". This tells you -which data type to use to understand the address fully. + Privileged users, like `root', can access any file regardless of its +permission bits. As a special case, for a file to be executable even +by a privileged user, at least one of its execute bits must be set. - The symbols in this section are defined in the header file -`sys/socket.h'. + +File: libc.info, Node: Setting Permissions, Next: Testing File Access, Prev: Access Permission, Up: File Attributes - - Data Type: struct sockaddr - The `struct sockaddr' type itself has the following members: +Assigning File Permissions +-------------------------- - `short int sa_family' - This is the code for the address format of this address. It - identifies the format of the data which follows. + The primitive functions for creating files (for example, `open' or +`mkdir') take a MODE argument, which specifies the file permissions to +give the newly created file. This mode is modified by the process's +"file creation mask", or "umask", before it is used. - `char sa_data[14]' - This is the actual socket address data, which is - format-dependent. Its length also depends on the format, and - may well be more than 14. The length 14 of `sa_data' is - essentially arbitrary. + The bits that are set in the file creation mask identify permissions +that are always to be disabled for newly created files. For example, if +you set all the "other" access bits in the mask, then newly created +files are not accessible at all to processes in the "other" category, +even if the MODE argument passed to the create function would permit +such access. In other words, the file creation mask is the complement +of the ordinary access permissions you want to grant. - Each address format has a symbolic name which starts with `AF_'. -Each of them corresponds to a `PF_' symbol which designates the -corresponding namespace. Here is a list of address format names: + Programs that create files typically specify a MODE argument that +includes all the permissions that make sense for the particular file. +For an ordinary file, this is typically read and write permission for +all classes of users. These permissions are then restricted as +specified by the individual user's own file creation mask. -`AF_LOCAL' - This designates the address format that goes with the local - namespace. (`PF_LOCAL' is the name of that namespace.) *Note - Local Namespace Details::, for information about this address - format. + To change the permission of an existing file given its name, call +`chmod'. This function uses the specified permission bits and ignores +the file creation mask. -`AF_UNIX' - This is a synonym for `AF_LOCAL'. Although `AF_LOCAL' is mandated - by POSIX.1g, `AF_UNIX' is portable to more systems. `AF_UNIX' was - the traditional name stemming from BSD, so even most POSIX systems - support it. It is also the name of choice in the Unix98 - specification. (The same is true for `PF_UNIX' vs. `PF_LOCAL'). + In normal use, the file creation mask is initialized by the user's +login shell (using the `umask' shell command), and inherited by all +subprocesses. Application programs normally don't need to worry about +the file creation mask. It will automatically do what it is supposed to +do. -`AF_FILE' - This is another synonym for `AF_LOCAL', for compatibility. - (`PF_FILE' is likewise a synonym for `PF_LOCAL'.) + When your program needs to create a file and bypass the umask for its +access permissions, the easiest way to do this is to use `fchmod' after +opening the file, rather than changing the umask. In fact, changing +the umask is usually done only by shells. They use the `umask' +function. -`AF_INET' - This designates the address format that goes with the Internet - namespace. (`PF_INET' is the name of that namespace.) *Note - Internet Address Formats::. + The functions in this section are declared in `sys/stat.h'. -`AF_INET6' - This is similar to `AF_INET', but refers to the IPv6 protocol. - (`PF_INET6' is the name of the corresponding namespace.) + - Function: mode_t umask (mode_t MASK) + The `umask' function sets the file creation mask of the current + process to MASK, and returns the previous value of the file + creation mask. -`AF_UNSPEC' - This designates no particular address format. It is used only in - rare cases, such as to clear out the default destination address - of a "connected" datagram socket. *Note Sending Datagrams::. + Here is an example showing how to read the mask with `umask' + without changing it permanently: - The corresponding namespace designator symbol `PF_UNSPEC' exists - for completeness, but there is no reason to use it in a program. + mode_t + read_umask (void) + { + mode_t mask = umask (0); + umask (mask); + return mask; + } - `sys/socket.h' defines symbols starting with `AF_' for many -different kinds of networks, most or all of which are not actually -implemented. We will document those that really work as we receive -information about how to use them. + However, it is better to use `getumask' if you just want to read + the mask value, because it is reentrant (at least if you use the + GNU operating system). - -File: libc.info, Node: Setting Address, Next: Reading Address, Prev: Address Formats, Up: Socket Addresses + - Function: mode_t getumask (void) + Return the current value of the file creation mask for the current + process.

The prototype for this function is in the header file -`sys/socket.h'. + In some situations it is desirable to allow programs to access files +or devices even if this is not possible with the permissions granted to +the user. One possible solution is to set the setuid-bit of the program +file. If such a program is started the _effective_ user ID of the +process is changed to that of the owner of the program file. So to +allow write access to files like `/etc/passwd', which normally can be +written only by the super-user, the modifying program will have to be +owned by `root' and the setuid-bit must be set. - - Function: int getsockname (int SOCKET, struct sockaddr *ADDR, - socklen_t *LENGTH-PTR) - The `getsockname' function returns information about the address - of the socket SOCKET in the locations specified by the ADDR and - LENGTH-PTR arguments. Note that the LENGTH-PTR is a pointer; you - should initialize it to be the allocation size of ADDR, and on - return it contains the actual size of the address data. + But beside the files the program is intended to change the user +should not be allowed to access any file to which s/he would not have +access anyway. The program therefore must explicitly check whether _the +user_ would have the necessary access to a file, before it reads or +writes the file. - The format of the address data depends on the socket namespace. - The length of the information is usually fixed for a given - namespace, so normally you can know exactly how much space is - needed and can provide that much. The usual practice is to - allocate a place for the value using the proper data type for the - socket's namespace, then cast its address to `struct sockaddr *' - to pass it to `getsockname'. + To do this, use the function `access', which checks for access +permission based on the process's _real_ user ID rather than the +effective user ID. (The setuid feature does not alter the real user ID, +so it reflects the user who actually ran the program.) - The return value is `0' on success and `-1' on error. The - following `errno' error conditions are defined for this function: + There is another way you could check this access, which is easy to +describe, but very hard to use. This is to examine the file mode bits +and mimic the system's own access computation. This method is +undesirable because many systems have additional access control +features; your program cannot portably mimic them, and you would not +want to try to keep track of the diverse features that different systems +have. Using `access' is simple and automatically does whatever is +appropriate for the system you are using. - `EBADF' - The SOCKET argument is not a valid file descriptor. + `access' is _only_ only appropriate to use in setuid programs.

So using `ftruncate' is no reliable way to increase + the file size but if it is possible it is probably the fastest + way. The function also operates on POSIX shared memory segments + if these are implemented by the system. -The Internet Namespace -====================== + `ftruncate' is especially useful in combination with `mmap'. + Since the mapped region must have a fixed size one cannot enlarge + the file by writing something beyond the last mapped page. + Instead one has to enlarge the file itself and then remap the file + with the new size. The example below shows how this works. - This section describes the details of the protocols and socket naming -conventions used in the Internet namespace. + When the source file is compiled with `_FILE_OFFSET_BITS == 64' the + `ftruncate' function is in fact `ftruncate64' and the type `off_t' + has 64 bits which makes it possible to handle files up to 2^63 + bytes in length. - Originally the Internet namespace used only IP version 4 (IPv4). -With the growing number of hosts on the Internet, a new protocol with a -larger address space was necessary: IP version 6 (IPv6).

Or you can use the `tmpnam' (better: +`tmpnam_r') function to provide a name for a temporary file and then +you can open it in the usual way with `fopen'. - Each computer also has one or more "host names", which are strings -of words separated by periods, as in `mescaline.gnu.org'. + The `tempnam' function is like `tmpnam' but lets you choose what +directory temporary files will go in, and something about what their +file names will look like. Important for multi-threaded programs is +that `tempnam' is reentrant, while `tmpnam' is not since it returns a +pointer to a static buffer. - Programs that let the user specify a host typically accept both -numeric addresses and host names. To open a connection a program needs -a numeric address, and so must convert a host name to the numeric -address it stands for. + These facilities are declared in the header file `stdio.h'. -* Menu: + - Function: FILE * tmpfile (void) + This function creates a temporary binary file for update mode, as + if by calling `fopen' with mode `"wb+"'.

Therefore this stream can + be used for files larger then 2^31 bytes on 32-bit machines. - Each computer on the Internet has one or more Internet addresses, -numbers which identify that computer among all those on the Internet. + Please note that the return type is still `FILE *'. There is no + special `FILE' type for the LFS interface. - An IPv4 Internet host address is a number containing four bytes of -data. Historically these are divided into two parts, a "network -number" and a "local network address number" within that network. In -the mid-1990s classless addresses were introduced which changed this -behavior. Since some functions implicitly expect the old definitions, -we first describe the class-based network and will then describe -classless addresses. IPv6 uses only classless addresses and therefore -the following paragraphs don't apply. + If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a 32 + bits machine this function is available under the name `tmpfile' + and so transparently replaces the old interface. - The class-based IPv4 network number consists of the first one, two or -three bytes; the rest of the bytes are the local address. + - Function: char * tmpnam (char *RESULT) + This function constructs and returns a valid file name that does + not refer to any existing file. If the RESULT argument is a null + pointer, the return value is a pointer to an internal static + string, which might be modified by subsequent calls and therefore + makes this function non-reentrant. Otherwise, the RESULT argument + should be a pointer to an array of at least `L_tmpnam' characters, + and the result is written into that array. - IPv4 network numbers are registered with the Network Information -Center (NIC), and are divided into three classes--A, B and C. The local -network address numbers of individual machines are registered with the -administrator of the particular network. + It is possible for `tmpnam' to fail if you call it too many times + without removing previously-created files. This is because the + limited length of the temporary file names gives room for only a + finite number of different names. If `tmpnam' fails it returns a + null pointer. - Class A networks have single-byte numbers in the range 0 to 127. -There are only a small number of Class A networks, but they can each -support a very large number of hosts. Medium-sized Class B networks -have two-byte network numbers, with the first byte in the range 128 to -191. Class C networks are the smallest; they have three-byte network -numbers, with the first byte in the range 192-255. Thus, the first 1, -2, or 3 bytes of an Internet address specify a network. The remaining -bytes of the Internet address specify the address within that network. + *Warning:* Between the time the pathname is constructed and the + file is created another process might have created a file with the + same name using `tmpnam', leading to a possible security hole. The + implementation generates names which can hardly be predicted, but + when opening the file you should use the `O_EXCL' flag. Using + `tmpfile' or `mkstemp' is a safe way to avoid this problem. - The Class A network 0 is reserved for broadcast to all networks. In -addition, the host number 0 within each network is reserved for -broadcast to all hosts in that network. These uses are obsolete now -but for compatibility reasons you shouldn't use network 0 and host -number 0. + - Function: char * tmpnam_r (char *RESULT) + This function is nearly identical to the `tmpnam' function, except + that if RESULT is a null pointer it returns a null pointer. - The Class A network 127 is reserved for loopback; you can always use -the Internet address `127.0.0.1' to refer to the host machine. + This guarantees reentrancy because the non-reentrant situation of + `tmpnam' cannot happen here. - Since a single machine can be a member of multiple networks, it can -have multiple Internet host addresses. However, there is never -supposed to be more than one machine with the same host address. + *Warning*: This function has the same security problems as + `tmpnam'. - There are four forms of the "standard numbers-and-dots notation" for -Internet addresses: + - Macro: int L_tmpnam + The value of this macro is an integer constant expression that + represents the minimum size of a string large enough to hold a + file name generated by the `tmpnam' function. -`A.B.C.D' - This specifies all four bytes of the address individually and is - the commonly used representation. + - Macro: int TMP_MAX + The macro `TMP_MAX' is a lower bound for how many temporary names + you can create with `tmpnam'. You can rely on being able to call + `tmpnam' at least this many times before it might fail saying you + have made too many temporary file names. -`A.B.C' - The last part of the address, C, is interpreted as a 2-byte - quantity. This is useful for specifying host addresses in a Class - B network with network address number `A.B'. + With the GNU library, you can create a very large number of + temporary file names. If you actually created the files, you + would probably run out of disk space before you ran out of names. + Some other systems have a fixed, small limit on the number of + temporary files. The limit is never less than `25'. -`A.B' - The last part of the address, B, is interpreted as a 3-byte - quantity. This is useful for specifying host addresses in a Class - A network with network address number A. + - Function: char * tempnam (const char *DIR, const char *PREFIX) + This function generates a unique temporary file name. If PREFIX + is not a null pointer, up to five characters of this string are + used as a prefix for the file name. The return value is a string + newly allocated with `malloc', so you should release its storage + with `free' when it is no longer needed. -`A' - If only one part is given, this corresponds directly to the host - address number. + Because the string is dynamically allocated this function is + reentrant. - Within each part of the address, the usual C conventions for -specifying the radix apply. In other words, a leading `0x' or `0X' -implies hexadecimal radix; a leading `0' implies octal; and otherwise -decimal radix is assumed. + The directory prefix for the temporary file name is determined by + testing each of the following in sequence. The directory must + exist and be writable. -Classless Addresses -................... + * The environment variable `TMPDIR', if it is defined. For + security reasons this only happens if the program is not SUID + or SGID enabled. - IPv4 addresses (and IPv6 addresses also) are now considered -classless; the distinction between classes A, B and C can be ignored. -Instead an IPv4 host address consists of a 32-bit address and a 32-bit -mask. The mask contains set bits for the network part and cleared bits -for the host part. The network part is contiguous from the left, with -the remaining bits representing the host. As a consequence, the -netmask can simply be specified as the number of set bits. Classes A, -B and C are just special cases of this general rule. For example, -class A addresses have a netmask of `255.0.0.0' or a prefix length of 8. + * The DIR argument, if it is not a null pointer. - Classless IPv4 network addresses are written in numbers-and-dots -notation with the prefix length appended and a slash as separator.

These six `X's are +replaced with six characters which make the whole string a unique file +name. Usually the template string is something like +`/tmp/PREFIXXXXXXX', and each program uses a unique PREFIX. - You will find older code that uses `unsigned long int' for IPv4 -Internet host addresses instead of `uint32_t' or `struct in_addr'. -Historically `unsigned long int' was a 32-bit number but with 64-bit -machines this has changed. Using `unsigned long int' might break the -code if it is used on machines where this type doesn't have 32 bits. -`uint32_t' is specified by Unix98 and guaranteed to have 32 bits. + *Note:* Because `mktemp' and `mkstemp' modify the template string, +you _must not_ pass string constants to them.

If TEMPLATE does not end + with `XXXXXX', `mkstemp' returns `-1' and does not modify TEMPLATE. - - Macro: uint32_t INADDR_LOOPBACK - You can use this constant to stand for "the address of this - machine," instead of finding its actual address. It is the IPv4 - Internet address `127.0.0.1', which is usually called `localhost'. - This special constant saves you the trouble of looking up the - address of your own machine. Also, the system usually implements - `INADDR_LOOPBACK' specially, avoiding any network traffic for the - case of one machine talking to itself. + The file is opened using mode `0600'. If the file is meant to be + used by other users this mode must be changed explicitly. - - Macro: uint32_t INADDR_ANY - You can use this constant to stand for "any incoming address" when - binding to an address. *Note Setting Address::. This is the usual - address to give in the `sin_addr' member of `struct sockaddr_in' - when you want to accept Internet connections. + Unlike `mktemp', `mkstemp' is actually guaranteed to create a unique +file that cannot possibly clash with any other program trying to create +a temporary file. This is because it works by calling `open' with the +`O_EXCL' flag, which says you want to create a new file and get an +error if the file already exists. - - Macro: uint32_t INADDR_BROADCAST - This constant is the address you use to send a broadcast message. + - Function: char * mkdtemp (char *TEMPLATE) + The `mkdtemp' function creates a directory with a unique name.

The data is +handled in a first-in, first-out (FIFO) order. The pipe has no name; it +is created for one use and both ends must be inherited from the single +process which created the pipe. - - Function: int inet_aton (const char *NAME, struct in_addr *ADDR) - This function converts the IPv4 Internet host address NAME from - the standard numbers-and-dots notation into binary data and stores - it in the `struct in_addr' that ADDR points to. `inet_aton' - returns nonzero if the address is valid, zero if not. + A "FIFO special file" is similar to a pipe, but instead of being an +anonymous, temporary connection, a FIFO has a name or names like any +other file.

If the input - is not valid, `inet_addr' returns `INADDR_NONE'. This is an - obsolete interface to `inet_aton', described immediately above. It - is obsolete because `INADDR_NONE' is a valid address - (255.255.255.255), and `inet_aton' provides a cleaner way to - indicate error return. + A pipe or FIFO has to be open at both ends simultaneously. If you +read from a pipe or FIFO file that doesn't have any processes writing +to it (perhaps because they have all closed the file, or exited), the +read returns end-of-file.

This +creates both the reading and writing ends of the pipe. It is not very +useful for a single process to use a pipe to talk to itself.

The -advantage of a symbolic name is that it is usually easier to remember. -For example, the machine with Internet address `158.121.106.19' is also -known as `alpha.gnu.org'; and other machines in the `gnu.org' domain -can refer to it simply as `alpha'. + +File: libc.info, Node: Pipe to a Subprocess, Next: FIFO Special Files, Prev: Creating a Pipe, Up: Pipes and FIFOs - Internally, the system uses a database to keep track of the mapping -between host names and host numbers. This database is usually either -the file `/etc/hosts' or an equivalent provided by a name server. The -functions and other symbols for accessing this database are declared in -`netdb.h'. They are BSD features, defined unconditionally if you -include `netdb.h'. +Pipe to a Subprocess +==================== - - Data Type: struct hostent - This data type is used to represent an entry in the hosts - database. It has the following members: + A common use of pipes is to send data to or receive data from a +program being run as a subprocess. One way of doing this is by using a +combination of `pipe' (to create the pipe), `fork' (to create the +subprocess), `dup2' (to force the subprocess to use the pipe as its +standard input or output channel), and `exec' (to execute the new +program). Or, you can use `popen' and `pclose'. - `char *h_name' - This is the "official" name of the host. + The advantage of using `popen' and `pclose' is that the interface is +much simpler and easier to use. But it doesn't offer as much +flexibility as using the low-level functions directly. - `char **h_aliases' - These are alternative names for the host, represented as a - null-terminated vector of strings. + - Function: FILE * popen (const char *COMMAND, const char *MODE) + The `popen' function is closely related to the `system' function; + see *Note Running a Command::. It executes the shell command + COMMAND as a subprocess. However, instead of waiting for the + command to complete, it creates a pipe to the subprocess and + returns a stream that corresponds to that pipe. - `int h_addrtype' - This is the host address type; in practice, its value is - always either `AF_INET' or `AF_INET6', with the latter being - used for IPv6 hosts. In principle other kinds of addresses - could be represented in the database as well as Internet - addresses; if this were done, you might find a value in this - field other than `AF_INET' or `AF_INET6'. *Note Socket - Addresses::. + If you specify a MODE argument of `"r"', you can read from the + stream to retrieve data from the standard output channel of the + subprocess. The subprocess inherits its standard input channel + from the parent process. - `int h_length' - This is the length, in bytes, of each address. + Similarly, if you specify a MODE argument of `"w"', you can write + to the stream to send data to the standard input channel of the + subprocess. The subprocess inherits its standard output channel + from the parent process. - `char **h_addr_list' - This is the vector of addresses for the host. (Recall that - the host might be connected to multiple networks and have - different addresses on each one.) The vector is terminated - by a null pointer. + In the event of an error `popen' returns a null pointer. This + might happen if the pipe or stream cannot be created, if the + subprocess cannot be forked, or if the program cannot be executed. - `char *h_addr' - This is a synonym for `h_addr_list[0]'; in other words, it is - the first host address. + - Function: int pclose (FILE *STREAM) + The `pclose' function is used to close a stream created by `popen'. + It waits for the child process to terminate and returns its status + value, as for the `system' function. - As far as the host database is concerned, each address is just a -block of memory `h_length' bytes long. But in other contexts there is -an implicit assumption that you can convert IPv4 addresses to a `struct -in_addr' or an `uint32_t'. Host addresses in a `struct hostent' -structure are always given in network byte order; see *Note Byte -Order::. + Here is an example showing how to use `popen' and `pclose' to filter +output through another program, in this case the paging program `more'. - You can use `gethostbyname', `gethostbyname2' or `gethostbyaddr' to -search the hosts database for information about a particular host. The -information is returned in a statically-allocated structure; you must -copy the information if you need to save it across calls. You can also -use `getaddrinfo' and `getnameinfo' to obtain this information. + #include + #include + + void + write_data (FILE * stream) + { + int i; + for (i = 0; i < 100; i++) + fprintf (stream, "%d\n", i); + if (ferror (stream)) + { + fprintf (stderr, "Output to stream failed.\n"); + exit (EXIT_FAILURE); + } + } + + int + main (void) + { + FILE *output; + + output = popen ("more", "w"); + if (!output) + { + fprintf (stderr, + "incorrect parameters or too many files.\n"); + return EXIT_FAILURE; + } + write_data (output); + if (pclose (output) != 0) + { + fprintf (stderr, + "Could not run more or other error.\n"); + } + return EXIT_SUCCESS; + } - - Function: struct hostent * gethostbyname (const char *NAME) - The `gethostbyname' function returns information about the host - named NAME. If the lookup fails, it returns a null pointer. + +File: libc.info, Node: FIFO Special Files, Next: Pipe Atomicity, Prev: Pipe to a Subprocess, Up: Pipes and FIFOs - - Function: struct hostent * gethostbyname2 (const char *NAME, int AF) - The `gethostbyname2' function is like `gethostbyname', but allows - the caller to specify the desired address family (e.g. `AF_INET' - or `AF_INET6') of the result. +FIFO Special Files +================== - - Function: struct hostent * gethostbyaddr (const char *ADDR, size_t - LENGTH, int FORMAT) - The `gethostbyaddr' function returns information about the host - with Internet address ADDR. The parameter ADDR is not really a - pointer to char - it can be a pointer to an IPv4 or an IPv6 - address. The LENGTH argument is the size (in bytes) of the address - at ADDR. FORMAT specifies the address format; for an IPv4 - Internet address, specify a value of `AF_INET'; for an IPv6 - Internet address, use `AF_INET6'. + A FIFO special file is similar to a pipe, except that it is created +in a different way. Instead of being an anonymous communications +channel, a FIFO special file is entered into the file system by calling +`mkfifo'. - If the lookup fails, `gethostbyaddr' returns a null pointer. + Once you have created a FIFO special file in this way, any process +can open it for reading or writing, in the same way as an ordinary file. +However, it has to be open at both ends simultaneously before you can +proceed to do any input or output operations on it. Opening a FIFO for +reading normally blocks until some other process opens the same FIFO for +writing, and vice versa. - If the name lookup by `gethostbyname' or `gethostbyaddr' fails, you -can find out the reason by looking at the value of the variable -`h_errno'. (It would be cleaner design for these functions to set -`errno', but use of `h_errno' is compatible with other systems.) + The `mkfifo' function is declared in the header file `sys/stat.h'. - Here are the error codes that you may find in `h_errno': + - Function: int mkfifo (const char *FILENAME, mode_t MODE) + The `mkfifo' function makes a FIFO special file with name + FILENAME. The MODE argument is used to set the file's + permissions; see *Note Setting Permissions::. -`HOST_NOT_FOUND' - No such host is known in the database. + The normal, successful return value from `mkfifo' is `0'. In the + case of an error, `-1' is returned. In addition to the usual file + name errors (*note File Name Errors::), the following `errno' + error conditions are defined for this function: -`TRY_AGAIN' - This condition happens when the name server could not be - contacted. If you try again later, you may succeed then. + `EEXIST' + The named file already exists. -`NO_RECOVERY' - A non-recoverable error occurred. + `ENOSPC' + The directory or file system cannot be extended. -`NO_ADDRESS' - The host database contains an entry for the name, but it doesn't - have an associated Internet address. + `EROFS' + The directory that would contain the file resides on a + read-only file system. - The lookup functions above all have one in common: they are not -reentrant and therefore unusable in multi-threaded applications. -Therefore provides the GNU C library a new set of functions which can be -used in this context. + +File: libc.info, Node: Pipe Atomicity, Prev: FIFO Special Files, Up: Pipes and FIFOs - - Function: int gethostbyname_r (const char *restrict NAME, struct - hostent *restrict RESULT_BUF, char *restrict BUF, size_t - BUFLEN, struct hostent **restrict RESULT, int *restrict - H_ERRNOP) - The `gethostbyname_r' function returns information about the host - named NAME. The caller must pass a pointer to an object of type - `struct hostent' in the RESULT_BUF parameter. In addition the - function may need extra buffer space and the caller must pass an - pointer and the size of the buffer in the BUF and BUFLEN - parameters. +Atomicity of Pipe I/O +===================== - A pointer to the buffer, in which the result is stored, is - available in `*RESULT' after the function call successfully - returned. If an error occurs or if no entry is found, the pointer - `*RESULT' is a null pointer. Success is signalled by a zero - return value. If the function failed the return value is an error - number. In addition to the errors defined for `gethostbyname' it - can also be `ERANGE'. In this case the call should be repeated - with a larger buffer. Additional error information is not stored - in the global variable `h_errno' but instead in the object pointed - to by H_ERRNOP. + Reading or writing pipe data is "atomic" if the size of data written +is not greater than `PIPE_BUF'. This means that the data transfer +seems to be an instantaneous unit, in that nothing else in the system +can observe a state in which it is partially complete. Atomic I/O may +not begin right away (it may need to wait for buffer space or for data), +but once it does begin it finishes immediately. - Here's a small example: - struct hostent * - gethostname (char *host) - { - struct hostent hostbuf, *hp; - size_t hstbuflen; - char *tmphstbuf; - int res; - int herr; - - hstbuflen = 1024; - /* Allocate buffer, remember to free it to avoid memory leakage. */ - tmphstbuf = malloc (hstbuflen); - - while ((res = gethostbyname_r (host, &hostbuf, tmphstbuf, hstbuflen, - &hp, &herr)) == ERANGE) - { - /* Enlarge the buffer. */ - hstbuflen *= 2; - tmphstbuf = realloc (tmphstbuf, hstbuflen); - } - /* Check for errors. */ - if (res || hp == NULL) - return NULL; - return hp; - } + Reading or writing a larger amount of data may not be atomic; for +example, output data from other processes sharing the descriptor may be +interspersed. Also, once `PIPE_BUF' characters have been written, +further writes will block until some characters are read. - - Function: int gethostbyname2_r (const char *NAME, int AF, struct - hostent *restrict RESULT_BUF, char *restrict BUF, size_t - BUFLEN, struct hostent **restrict RESULT, int *restrict - H_ERRNOP) - The `gethostbyname2_r' function is like `gethostbyname_r', but - allows the caller to specify the desired address family (e.g. - `AF_INET' or `AF_INET6') for the result. + *Note Limits for Files::, for information about the `PIPE_BUF' +parameter. - - Function: int gethostbyaddr_r (const char *ADDR, size_t LENGTH, int - FORMAT, struct hostent *restrict RESULT_BUF, char *restrict - BUF, size_t BUFLEN, struct hostent **restrict RESULT, int - *restrict H_ERRNOP) - The `gethostbyaddr_r' function returns information about the host - with Internet address ADDR. The parameter ADDR is not really a - pointer to char - it can be a pointer to an IPv4 or an IPv6 - address. The LENGTH argument is the size (in bytes) of the address - at ADDR. FORMAT specifies the address format; for an IPv4 - Internet address, specify a value of `AF_INET'; for an IPv6 - Internet address, use `AF_INET6'. + +File: libc.info, Node: Sockets, Next: Low-Level Terminal Interface, Prev: Pipes and FIFOs, Up: Top - Similar to the `gethostbyname_r' function, the caller must provide - buffers for the result and memory used internally. In case of - success the function returns zero. Otherwise the value is an - error number where `ERANGE' has the special meaning that the - caller-provided buffer is too small. +Sockets +******* - You can also scan the entire hosts database one entry at a time using -`sethostent', `gethostent' and `endhostent'. Be careful when using -these functions because they are not reentrant. + This chapter describes the GNU facilities for interprocess +communication using sockets. - - Function: void sethostent (int STAYOPEN) - This function opens the hosts database to begin scanning it. You - can then call `gethostent' to read the entries. + A "socket" is a generalized interprocess communication channel. +Like a pipe, a socket is represented as a file descriptor. Unlike pipes +sockets support communication between unrelated processes, and even +between processes running on different machines that communicate over a +network. Sockets are the primary means of communicating with other +machines; `telnet', `rlogin', `ftp', `talk' and the other familiar +network programs use sockets. - If the STAYOPEN argument is nonzero, this sets a flag so that - subsequent calls to `gethostbyname' or `gethostbyaddr' will not - close the database (as they usually would). This makes for more - efficiency if you call those functions several times, by avoiding - reopening the database for each call. + Not all operating systems support sockets. In the GNU library, the +header file `sys/socket.h' exists regardless of the operating system, +and the socket functions always exist, but if the system does not +really support sockets these functions always fail. - - Function: struct hostent * gethostent (void) - This function returns the next entry in the hosts database.

Port numbers range from 0 -to 65,535. + When you create a socket, you must specify the style of communication +you want to use and the type of protocol that should implement it. The +"communication style" of a socket defines the user-level semantics of +sending and receiving data on the socket. Choosing a communication +style specifies the answers to questions such as these: - Port numbers less than `IPPORT_RESERVED' are reserved for standard -servers, such as `finger' and `telnet'. There is a database that keeps -track of these, and you can use the `getservbyname' function to map a -service name onto a port number; see *Note Services Database::. + * *What are the units of data transmission?* Some communication + styles regard the data as a sequence of bytes with no larger + structure; others group the bytes into records (which are known in + this context as "packets"). - If you write a server that is not one of the standard ones defined in -the database, you must choose a port number for it. Use a number -greater than `IPPORT_USERRESERVED'; such numbers are reserved for -servers and won't ever be generated automatically by the system. -Avoiding conflicts with servers being run by other users is up to you. + * *Can data be lost during normal operation?* Some communication + styles guarantee that all the data sent arrives in the order it was + sent (barring system or network crashes); other styles occasionally + lose data as a normal part of operation, and may sometimes deliver + packets more than once or in the wrong order. - When you use a socket without specifying its address, the system -generates a port number for it. This number is between -`IPPORT_RESERVED' and `IPPORT_USERRESERVED'. + Designing a program to use unreliable communication styles usually + involves taking precautions to detect lost or misordered packets + and to retransmit data as needed. - On the Internet, it is actually legitimate to have two different -sockets with the same port number, as long as they never both try to -communicate with the same socket address (host address plus port -number). You shouldn't duplicate a port number except in special -circumstances where a higher-level protocol requires it. Normally, the -system won't let you do it; `bind' normally insists on distinct port -numbers. To reuse a port number, you must set the socket option -`SO_REUSEADDR'. *Note Socket-Level Options::. + * *Is communication entirely with one partner?* Some communication + styles are like a telephone call--you make a "connection" with one + remote socket and then exchange data freely. Other styles are + like mailing letters--you specify a destination address for each + message you send. - These macros are defined in the header file `netinet/in.h'. + You must also choose a "namespace" for naming the socket. A socket +name ("address") is meaningful only in the context of a particular +namespace. In fact, even the data type to use for a socket name may +depend on the namespace. Namespaces are also called "domains", but we +avoid that word as it can be confused with other usage of the same +term. Each namespace has a symbolic name that starts with `PF_'. A +corresponding symbolic name starting with `AF_' designates the address +format for that namespace. - - Macro: int IPPORT_RESERVED - Port numbers less than `IPPORT_RESERVED' are reserved for - superuser use. + Finally you must choose the "protocol" to carry out the +communication. The protocol determines what low-level mechanism is used +to transmit and receive data. Each protocol is valid for a particular +namespace and communication style; a namespace is sometimes called a +"protocol family" because of this, which is why the namespace names +start with `PF_'. - - Macro: int IPPORT_USERRESERVED - Port numbers greater than or equal to `IPPORT_USERRESERVED' are - reserved for explicit use; they will never be allocated - automatically. + The rules of a protocol apply to the data passing between two +programs, perhaps on different computers; most of these rules are +handled by the operating system and you need not know about them. What +you do need to know about protocols is this: - -File: libc.info, Node: Services Database, Next: Byte Order, Prev: Ports, Up: Internet Namespace + * In order to have communication between two sockets, they must + specify the _same_ protocol. -The Services Database ---------------------- + * Each protocol is meaningful with particular style/namespace + combinations and cannot be used with inappropriate combinations. + For example, the TCP protocol fits only the byte stream style of + communication and the Internet namespace. - The database that keeps track of "well-known" services is usually -either the file `/etc/services' or an equivalent from a name server. -You can use these utilities, declared in `netdb.h', to access the -services database. + * For each combination of style and namespace there is a "default + protocol", which you can request by specifying 0 as the protocol + number. And that's what you should normally do--use the default. - - Data Type: struct servent - This data type holds information about entries from the services - database. It has the following members: + Throughout the following description at various places +variables/parameters to denote sizes are required. And here the trouble +starts. In the first implementations the type of these variables was +simply `int'. On most machines at that time an `int' was 32 bits wide, +which created a _de facto_ standard requiring 32-bit variables. This +is important since references to variables of this type are passed to +the kernel. - `char *s_name' - This is the "official" name of the service. + Then the POSIX people came and unified the interface with the words +"all size values are of type `size_t'". On 64-bit machines `size_t' is +64 bits wide, so pointers to variables were no longer possible. - `char **s_aliases' - These are alternate names for the service, represented as an - array of strings. A null pointer terminates the array. + The Unix98 specification provides a solution by introducing a type +`socklen_t'. This type is used in all of the cases that POSIX changed +to use `size_t'. The only requirement of this type is that it be an +unsigned type of at least 32 bits. Therefore, implementations which +require that references to 32-bit variables be passed can be as happy +as implementations which use 64-bit values. - `int s_port' - This is the port number for the service. Port numbers are - given in network byte order; see *Note Byte Order::. + +File: libc.info, Node: Communication Styles, Next: Socket Addresses, Prev: Socket Concepts, Up: Sockets - `char *s_proto' - This is the name of the protocol to use with this service. - *Note Protocols Database::. +Communication Styles +==================== - To get information about a particular service, use the -`getservbyname' or `getservbyport' functions.

If it can't find such a service, - it returns a null pointer. + - Macro: int SOCK_STREAM + The `SOCK_STREAM' style is like a pipe (*note Pipes and FIFOs::). + It operates over a connection with a particular remote socket and + transmits data reliably as a stream of bytes. - This function is useful for servers as well as for clients; servers - use it to determine which port they should listen on (*note - Listening::). + Use of this style is covered in detail in *Note Connections::. - - Function: struct servent * getservbyport (int PORT, const char - *PROTO) - The `getservbyport' function returns information about the service - at port PORT using protocol PROTO. If it can't find such a - service, it returns a null pointer. + - Macro: int SOCK_DGRAM + The `SOCK_DGRAM' style is used for sending individually-addressed + packets unreliably. It is the diametrical opposite of + `SOCK_STREAM'. -You can also scan the services database using `setservent', -`getservent' and `endservent'. Be careful when using these functions -because they are not reentrant. + Each time you write data to a socket of this kind, that data + becomes one packet. Since `SOCK_DGRAM' sockets do not have + connections, you must specify the recipient address with each + packet. - - Function: void setservent (int STAYOPEN) - This function opens the services database to begin scanning it. + The only guarantee that the system makes about your requests to + transmit data is that it will try its best to deliver each packet + you send. It may succeed with the sixth packet after failing with + the fourth and fifth packets; the seventh packet may arrive before + the sixth, and may arrive a second time after the sixth. - If the STAYOPEN argument is nonzero, this sets a flag so that - subsequent calls to `getservbyname' or `getservbyport' will not - close the database (as they usually would). This makes for more - efficiency if you call those functions several times, by avoiding - reopening the database for each call. + The typical use for `SOCK_DGRAM' is in situations where it is + acceptable to simply re-send a packet if no response is seen in a + reasonable amount of time. - - Function: struct servent * getservent (void) - This function returns the next entry in the services database. If - there are no more entries, it returns a null pointer. + *Note Datagrams::, for detailed information about how to use + datagram sockets. - - Function: void endservent (void) - This function closes the services database. + - Macro: int SOCK_RAW + This style provides access to low-level network protocols and + interfaces. Ordinary user programs usually have no need to use + this style.  -File: libc.info, Node: Byte Order, Next: Inet Example, Prev: Services Database, Up: Internet Namespace +File: libc.info, Node: Socket Addresses, Next: Interface Naming, Prev: Communication Styles, Up: Sockets -Byte Order Conversion ---------------------- +Socket Addresses +================ - Different kinds of computers use different conventions for the -ordering of bytes within a word. Some computers put the most -significant byte within a word first (this is called "big-endian" -order), and others put it last ("little-endian" order). + The name of a socket is normally called an "address". The functions +and symbols for dealing with socket addresses were named +inconsistently, sometimes using the term "name" and sometimes using +"address". You can regard these terms as synonymous where sockets are +concerned. - So that machines with different byte order conventions can -communicate, the Internet protocols specify a canonical byte order -convention for data transmitted over the network. This is known as -"network byte order". + A socket newly created with the `socket' function has no address. +Other processes can find it for communication only if you give it an +address. We call this "binding" the address to the socket, and the way +to do it is with the `bind' function. - When establishing an Internet socket connection, you must make sure -that the data in the `sin_port' and `sin_addr' members of the -`sockaddr_in' structure are represented in network byte order. If you -are encoding integer data in the messages sent through the socket, you -should convert this to network byte order too. If you don't do this, -your program may fail when running on or talking to other kinds of -machines. + You need be concerned with the address of a socket if other processes +are to find it and start communicating with it. You can specify an +address for other sockets, but this is usually pointless; the first time +you send data from a socket, or use it to initiate a connection, the +system assigns an address automatically if you have not specified one. - If you use `getservbyname' and `gethostbyname' or `inet_addr' to get -the port number and host address, the values are already in network -byte order, and you can copy them directly into the `sockaddr_in' -structure. + Occasionally a client needs to specify an address because the server +discriminates based on address; for example, the rsh and rlogin +protocols look at the client's socket address and only bypass password +checking if it is less than `IPPORT_RESERVED' (*note Ports::). - Otherwise, you have to convert the values explicitly. Use `htons' -and `ntohs' to convert values for the `sin_port' member. Use `htonl' -and `ntohl' to convert IPv4 addresses for the `sin_addr' member. -(Remember, `struct in_addr' is equivalent to `uint32_t'.) These -functions are declared in `netinet/in.h'. + The details of socket addresses vary depending on what namespace you +are using. *Note Local Namespace::, or *Note Internet Namespace::, for +specific information. - - Function: uint16_t htons (uint16_t HOSTSHORT) - This function converts the `uint16_t' integer HOSTSHORT from host - byte order to network byte order. + Regardless of the namespace, you use the same functions `bind' and +`getsockname' to set and examine a socket's address. These functions +use a phony data type, `struct sockaddr *', to accept the address. In +practice, the address lives in a structure of some other data type +appropriate to the address format you are using, but you cast its +address to `struct sockaddr *' when you pass it to `bind'. - - Function: uint16_t ntohs (uint16_t NETSHORT) - This function converts the `uint16_t' integer NETSHORT from - network byte order to host byte order. +* Menu: - - Function: uint32_t htonl (uint32_t HOSTLONG) - This function converts the `uint32_t' integer HOSTLONG from host - byte order to network byte order. +* Address Formats:: About `struct sockaddr'. +* Setting Address:: Binding an address to a socket. +* Reading Address:: Reading the address of a socket. - This is used for IPv4 Internet addresses. + +File: libc.info, Node: Address Formats, Next: Setting Address, Up: Socket Addresses - - Function: uint32_t ntohl (uint32_t NETLONG) - This function converts the `uint32_t' integer NETLONG from network - byte order to host byte order. +Address Formats +--------------- - This is used for IPv4 Internet addresses. + The functions `bind' and `getsockname' use the generic data type +`struct sockaddr *' to represent a pointer to a socket address. You +can't use this data type effectively to interpret an address or +construct one; for that, you must use the proper data type for the +socket's namespace. - -File: libc.info, Node: Protocols Database, Next: Ports, Prev: Host Addresses, Up: Internet Namespace + Thus, the usual practice is to construct an address of the proper +namespace-specific type, then cast a pointer to `struct sockaddr *' +when you call `bind' or `getsockname'. -Protocols Database ------------------- + The one piece of information that you can get from the `struct +sockaddr' data type is the "address format designator". This tells you +which data type to use to understand the address fully. - The communications protocol used with a socket controls low-level -details of how data are exchanged. For example, the protocol implements -things like checksums to detect errors in transmissions, and routing -instructions for messages. Normal user programs have little reason to -mess with these details directly. + The symbols in this section are defined in the header file +`sys/socket.h'. - The default communications protocol for the Internet namespace -depends on the communication style. For stream communication, the -default is TCP ("transmission control protocol"). For datagram -communication, the default is UDP ("user datagram protocol"). For -reliable datagram communication, the default is RDP ("reliable datagram -protocol"). You should nearly always use the default. + - Data Type: struct sockaddr + The `struct sockaddr' type itself has the following members: - Internet protocols are generally specified by a name instead of a -number. The network protocols that a host knows about are stored in a -database. This is usually either derived from the file -`/etc/protocols', or it may be an equivalent provided by a name server. -You look up the protocol number associated with a named protocol in -the database using the `getprotobyname' function. + `short int sa_family' + This is the code for the address format of this address. It + identifies the format of the data which follows. - Here are detailed descriptions of the utilities for accessing the -protocols database. These are declared in `netdb.h'. + `char sa_data[14]' + This is the actual socket address data, which is + format-dependent. Its length also depends on the format, and + may well be more than 14. The length 14 of `sa_data' is + essentially arbitrary. - - Data Type: struct protoent - This data type is used to represent entries in the network - protocols database. It has the following members: + Each address format has a symbolic name which starts with `AF_'. +Each of them corresponds to a `PF_' symbol which designates the +corresponding namespace. Here is a list of address format names: - `char *p_name' - This is the official name of the protocol. +`AF_LOCAL' + This designates the address format that goes with the local + namespace. (`PF_LOCAL' is the name of that namespace.) *Note + Local Namespace Details::, for information about this address + format. - `char **p_aliases' - These are alternate names for the protocol, specified as an - array of strings. The last element of the array is a null - pointer. +`AF_UNIX' + This is a synonym for `AF_LOCAL'. Although `AF_LOCAL' is mandated + by POSIX.1g, `AF_UNIX' is portable to more systems. `AF_UNIX' was + the traditional name stemming from BSD, so even most POSIX systems + support it. It is also the name of choice in the Unix98 + specification. (The same is true for `PF_UNIX' vs. `PF_LOCAL'). - `int p_proto' - This is the protocol number (in host byte order); use this - member as the PROTOCOL argument to `socket'. +`AF_FILE' + This is another synonym for `AF_LOCAL', for compatibility. + (`PF_FILE' is likewise a synonym for `PF_LOCAL'.) - You can use `getprotobyname' and `getprotobynumber' to search the -protocols database for a specific protocol. The information is -returned in a statically-allocated structure; you must copy the -information if you need to save it across calls. +`AF_INET' + This designates the address format that goes with the Internet + namespace. (`PF_INET' is the name of that namespace.) *Note + Internet Address Formats::. - - Function: struct protoent * getprotobyname (const char *NAME) - The `getprotobyname' function returns information about the - network protocol named NAME. If there is no such protocol, it - returns a null pointer. +`AF_INET6' + This is similar to `AF_INET', but refers to the IPv6 protocol. + (`PF_INET6' is the name of the corresponding namespace.) - - Function: struct protoent * getprotobynumber (int PROTOCOL) - The `getprotobynumber' function returns information about the - network protocol with number PROTOCOL. If there is no such - protocol, it returns a null pointer. +`AF_UNSPEC' + This designates no particular address format. It is used only in + rare cases, such as to clear out the default destination address + of a "connected" datagram socket. *Note Sending Datagrams::. - You can also scan the whole protocols database one protocol at a -time by using `setprotoent', `getprotoent' and `endprotoent'. Be -careful when using these functions because they are not reentrant. + The corresponding namespace designator symbol `PF_UNSPEC' exists + for completeness, but there is no reason to use it in a program. - - Function: void setprotoent (int STAYOPEN) - This function opens the protocols database to begin scanning it. + `sys/socket.h' defines symbols starting with `AF_' for many +different kinds of networks, most or all of which are not actually +implemented. We will document those that really work as we receive +information about how to use them. - If the STAYOPEN argument is nonzero, this sets a flag so that - subsequent calls to `getprotobyname' or `getprotobynumber' will - not close the database (as they usually would). This makes for - more efficiency if you call those functions several times, by - avoiding reopening the database for each call. + +File: libc.info, Node: Setting Address, Next: Reading Address, Prev: Address Formats, Up: Socket Addresses - - Function: struct protoent * getprotoent (void) - This function returns the next entry in the protocols database. It - returns a null pointer if there are no more entries. +Setting the Address of a Socket +------------------------------- - - Function: void endprotoent (void) - This function closes the protocols database. + Use the `bind' function to assign an address to a socket.

First it must use the `listen' function to -enable connection requests on the socket, and then accept each incoming -connection with a call to `accept' (*note Accepting Connections::). -Once connection requests are enabled on a server socket, the `select' -function reports when the socket has a connection ready to be accepted -(*note Waiting for I/O::). + Each computer on the Internet has one or more Internet addresses, +numbers which identify that computer among all those on the Internet. - The `listen' function is not allowed for sockets using -connectionless communication styles. + An IPv4 Internet host address is a number containing four bytes of +data. Historically these are divided into two parts, a "network +number" and a "local network address number" within that network. In +the mid-1990s classless addresses were introduced which changed this +behavior. Since some functions implicitly expect the old definitions, +we first describe the class-based network and will then describe +classless addresses. IPv6 uses only classless addresses and therefore +the following paragraphs don't apply. - You can write a network server that does not even start running -until a connection to it is requested. *Note Inetd Servers::. + The class-based IPv4 network number consists of the first one, two or +three bytes; the rest of the bytes are the local address. - In the Internet namespace, there are no special protection mechanisms -for controlling access to a port; any process on any machine can make a -connection to your server. If you want to restrict access to your -server, make it examine the addresses associated with connection -requests or implement some other handshaking or identification protocol. + IPv4 network numbers are registered with the Network Information +Center (NIC), and are divided into three classes--A, B and C. The local +network address numbers of individual machines are registered with the +administrator of the particular network. - In the local namespace, the ordinary file protection bits control -who has access to connect to the socket. + Class A networks have single-byte numbers in the range 0 to 127. +There are only a small number of Class A networks, but they can each +support a very large number of hosts. Medium-sized Class B networks +have two-byte network numbers, with the first byte in the range 128 to +191. Class C networks are the smallest; they have three-byte network +numbers, with the first byte in the range 192-255. Thus, the first 1, +2, or 3 bytes of an Internet address specify a network. The remaining +bytes of the Internet address specify the address within that network. - - Function: int listen (int SOCKET, unsigned int N) - The `listen' function enables the socket SOCKET to accept - connections, thus making it a server socket. + The Class A network 0 is reserved for broadcast to all networks. In +addition, the host number 0 within each network is reserved for +broadcast to all hosts in that network. These uses are obsolete now +but for compatibility reasons you shouldn't use network 0 and host +number 0. - The argument N specifies the length of the queue for pending - connections. When the queue fills, new clients attempting to - connect fail with `ECONNREFUSED' until the server calls `accept' to - accept a connection from the queue. + The Class A network 127 is reserved for loopback; you can always use +the Internet address `127.0.0.1' to refer to the host machine. - The `listen' function returns `0' on success and `-1' on failure. - The following `errno' error conditions are defined for this - function: + Since a single machine can be a member of multiple networks, it can +have multiple Internet host addresses. However, there is never +supposed to be more than one machine with the same host address. - `EBADF' - The argument SOCKET is not a valid file descriptor. + There are four forms of the "standard numbers-and-dots notation" for +Internet addresses: - `ENOTSOCK' - The argument SOCKET is not a socket. +`A.B.C.D' + This specifies all four bytes of the address individually and is + the commonly used representation. - `EOPNOTSUPP' - The socket SOCKET does not support this operation. +`A.B.C' + The last part of the address, C, is interpreted as a 2-byte + quantity. This is useful for specifying host addresses in a Class + B network with network address number `A.B'. - -File: libc.info, Node: Accepting Connections, Next: Who is Connected, Prev: Listening, Up: Connections +`A.B' + The last part of the address, B, is interpreted as a 3-byte + quantity. This is useful for specifying host addresses in a Class + A network with network address number A. -Accepting Connections ---------------------- +`A' + If only one part is given, this corresponds directly to the host + address number. - When a server receives a connection request, it can complete the -connection by accepting the request. Use the function `accept' to do -this. + Within each part of the address, the usual C conventions for +specifying the radix apply. In other words, a leading `0x' or `0X' +implies hexadecimal radix; a leading `0' implies octal; and otherwise +decimal radix is assumed. - A socket that has been established as a server can accept connection -requests from multiple clients. The server's original socket _does not -become part of the connection_; instead, `accept' makes a new socket -which participates in the connection. `accept' returns the descriptor -for this socket. The server's original socket remains available for -listening for further connection requests. +Classless Addresses +................... - The number of pending connection requests on a server socket is -finite. If connection requests arrive from clients faster than the -server can act upon them, the queue can fill up and additional requests -are refused with an `ECONNREFUSED' error. You can specify the maximum -length of this queue as an argument to the `listen' function, although -the system may also impose its own internal limit on the length of this -queue. + IPv4 addresses (and IPv6 addresses also) are now considered +classless; the distinction between classes A, B and C can be ignored. +Instead an IPv4 host address consists of a 32-bit address and a 32-bit +mask. The mask contains set bits for the network part and cleared bits +for the host part. The network part is contiguous from the left, with +the remaining bits representing the host. As a consequence, the +netmask can simply be specified as the number of set bits. Classes A, +B and C are just special cases of this general rule. For example, +class A addresses have a netmask of `255.0.0.0' or a prefix length of 8. - - Function: int accept (int SOCKET, struct sockaddr *ADDR, socklen_t - *LENGTH_PTR) - This function is used to accept a connection request on the server - socket SOCKET. + Classless IPv4 network addresses are written in numbers-and-dots +notation with the prefix length appended and a slash as separator. For +example the class A network 10 is written as `10.0.0.0/8'. - The `accept' function waits if there are no connections pending, - unless the socket SOCKET has nonblocking mode set. (You can use - `select' to wait for a pending connection, with a nonblocking - socket.) *Note File Status Flags::, for information about - nonblocking mode. +IPv6 Addresses +.............. - The ADDR and LENGTH-PTR arguments are used to return information - about the name of the client socket that initiated the connection. - *Note Socket Addresses::, for information about the format of the - information. + IPv6 addresses contain 128 bits (IPv4 has 32 bits) of data. A host +address is usually written as eight 16-bit hexadecimal numbers that are +separated by colons. Two colons are used to abbreviate strings of +consecutive zeros. For example, the IPv6 loopback address +`0:0:0:0:0:0:0:1' can just be written as `::1'. - Accepting a connection does not make SOCKET part of the - connection. Instead, it creates a new socket which becomes - connected. The normal return value of `accept' is the file - descriptor for the new socket. + +File: libc.info, Node: Host Address Data Type, Next: Host Address Functions, Prev: Abstract Host Addresses, Up: Host Addresses - After `accept', the original socket SOCKET remains open and - unconnected, and continues listening until you close it. You can - accept further connections with SOCKET by calling `accept' again. +Host Address Data Type +...................... - If an error occurs, `accept' returns `-1'. The following `errno' - error conditions are defined for this function: + IPv4 Internet host addresses are represented in some contexts as +integers (type `uint32_t'). In other contexts, the integer is packaged +inside a structure of type `struct in_addr'. It would be better if the +usage were made consistent, but it is not hard to extract the integer +from the structure or put the integer into a structure. - `EBADF' - The SOCKET argument is not a valid file descriptor. + You will find older code that uses `unsigned long int' for IPv4 +Internet host addresses instead of `uint32_t' or `struct in_addr'. +Historically `unsigned long int' was a 32-bit number but with 64-bit +machines this has changed. Using `unsigned long int' might break the +code if it is used on machines where this type doesn't have 32 bits. +`uint32_t' is specified by Unix98 and guaranteed to have 32 bits. - `ENOTSOCK' - The descriptor SOCKET argument is not a socket. + IPv6 Internet host addresses have 128 bits and are packaged inside a +structure of type `struct in6_addr'. - `EOPNOTSUPP' - The descriptor SOCKET does not support this operation. + The following basic definitions for Internet addresses are declared +in the header file `netinet/in.h': - `EWOULDBLOCK' - SOCKET has nonblocking mode set, and there are no pending - connections immediately available. + - Data Type: struct in_addr + This data type is used in certain contexts to contain an IPv4 + Internet host address.

Using these styles, -you group data into packets and each packet is an independent -communication. You specify the destination for each packet -individually. + Different kinds of computers use different conventions for the +ordering of bytes within a word. Some computers put the most +significant byte within a word first (this is called "big-endian" +order), and others put it last ("little-endian" order). - Datagram packets are like letters: you send each one independently -with its own destination address, and they may arrive in the wrong -order or not at all. + So that machines with different byte order conventions can +communicate, the Internet protocols specify a canonical byte order +convention for data transmitted over the network. This is known as +"network byte order". - The `listen' and `accept' functions are not allowed for sockets -using connectionless communication styles. + When establishing an Internet socket connection, you must make sure +that the data in the `sin_port' and `sin_addr' members of the +`sockaddr_in' structure are represented in network byte order. If you +are encoding integer data in the messages sent through the socket, you +should convert this to network byte order too. If you don't do this, +your program may fail when running on or talking to other kinds of +machines. -* Menu: + If you use `getservbyname' and `gethostbyname' or `inet_addr' to get +the port number and host address, the values are already in network +byte order, and you can copy them directly into the `sockaddr_in' +structure. -* Sending Datagrams:: Sending packets on a datagram socket. -* Receiving Datagrams:: Receiving packets on a datagram socket. -* Datagram Example:: An example program: packets sent over a - datagram socket in the local namespace. -* Example Receiver:: Another program, that receives those packets. + Otherwise, you have to convert the values explicitly.

For example, the protocol implements +things like checksums to detect errors in transmissions, and routing +instructions for messages. Normal user programs have little reason to +mess with these details directly. - You can call `connect' on a datagram socket, but this only specifies -a default destination for further data transmission on the socket. -When a socket has a default destination you can use `send' (*note -Sending Data::) or even `write' (*note I/O Primitives::) to send a -packet there. You can cancel the default destination by calling -`connect' using an address format of `AF_UNSPEC' in the ADDR argument. -*Note Connecting::, for more information about the `connect' function. + The default communications protocol for the Internet namespace +depends on the communication style. For stream communication, the +default is TCP ("transmission control protocol"). For datagram +communication, the default is UDP ("user datagram protocol").

You can find out whether a file -descriptor is associated with a terminal by using the `isatty' function. +Making a Connection +------------------- - Prototypes for the functions in this section are declared in the -header file `unistd.h'. + In making a connection, the client makes a connection while the +server waits for and accepts the connection. Here we discuss what the +client program must do with the `connect' function, which is declared in +`sys/socket.h'. - - Function: int isatty (int FILEDES) - This function returns `1' if FILEDES is a file descriptor - associated with an open terminal device, and 0 otherwise. + - Function: int connect (int SOCKET, struct sockaddr *ADDR, socklen_t + LENGTH) + The `connect' function initiates a connection from the socket with + file descriptor SOCKET to the socket whose address is specified by + the ADDR and LENGTH arguments. (This socket is typically on + another machine, and it must be already set up as a server.) + *Note Socket Addresses::, for information about how these + arguments are interpreted. - If a file descriptor is associated with a terminal, you can get its -associated file name using the `ttyname' function. See also the -`ctermid' function, described in *Note Identifying the Terminal::. + Normally, `connect' waits until the server responds to the request + before it returns. You can set nonblocking mode on the socket + SOCKET to make `connect' return immediately without waiting for + the response. *Note File Status Flags::, for information about + nonblocking mode. - - Function: char * ttyname (int FILEDES) - If the file descriptor FILEDES is associated with a terminal - device, the `ttyname' function returns a pointer to a - statically-allocated, null-terminated string containing the file - name of the terminal file. The value is a null pointer if the - file descriptor isn't associated with a terminal, or the file name - cannot be determined. + The normal return value from `connect' is `0'. If an error + occurs, `connect' returns `-1'. The following `errno' error + conditions are defined for this function: - - Function: int ttyname_r (int FILEDES, char *BUF, size_t LEN) - The `ttyname_r' function is similar to the `ttyname' function - except that it places its result into the user-specified buffer - starting at BUF with length LEN. + `EBADF' + The socket SOCKET is not a valid file descriptor. - The normal return value from `ttyname_r' is 0. Otherwise an error - number is returned to indicate the error. The following `errno' - error conditions are defined for this function: + `ENOTSOCK' + File descriptor SOCKET is not a socket. - `EBADF' - The FILEDES argument is not a valid file descriptor. + `EADDRNOTAVAIL' + The specified address is not available on the remote machine. - `ENOTTY' - The FILEDES is not associated with a terminal. + `EAFNOSUPPORT' + The namespace of the ADDR is not supported by this socket. - `ERANGE' - The buffer length LEN is too small to store the string to be - returned. + `EISCONN' + The socket SOCKET is already connected. - -File: libc.info, Node: I/O Queues, Next: Canonical or Not, Prev: Is It a Terminal, Up: Low-Level Terminal Interface + `ETIMEDOUT' + The attempt to establish the connection timed out. -I/O Queues -========== + `ECONNREFUSED' + The server has actively refused to establish the connection. - Many of the remaining functions in this section refer to the input -and output queues of a terminal device. These queues implement a form -of buffering _within the kernel_ independent of the buffering -implemented by I/O streams (*note I/O on Streams::). + `ENETUNREACH' + The network of the given ADDR isn't reachable from this host. - The "terminal input queue" is also sometimes referred to as its -"typeahead buffer". It holds the characters that have been received -from the terminal but not yet read by any process. + `EADDRINUSE' + The socket address of the given ADDR is already in use. - The size of the input queue is described by the `MAX_INPUT' and -`_POSIX_MAX_INPUT' parameters; see *Note Limits for Files::. You are -guaranteed a queue size of at least `MAX_INPUT', but the queue might be -larger, and might even dynamically change size. If input flow control -is enabled by setting the `IXOFF' input mode bit (*note Input Modes::), -the terminal driver transmits STOP and START characters to the terminal -when necessary to prevent the queue from overflowing. Otherwise, input -may be lost if it comes in too fast from the terminal. In canonical -mode, all input stays in the queue until a newline character is -received, so the terminal input queue can fill up when you type a very -long line. *Note Canonical or Not::. + `EINPROGRESS' + The socket SOCKET is non-blocking and the connection could + not be established immediately. You can determine when the + connection is completely established with `select'; *note + Waiting for I/O::. Another `connect' call on the same + socket, before the connection is completely established, will + fail with `EALREADY'. - The "terminal output queue" is like the input queue, but for output; -it contains characters that have been written by processes, but not yet -transmitted to the terminal. If output flow control is enabled by -setting the `IXON' input mode bit (*note Input Modes::), the terminal -driver obeys START and STOP characters sent by the terminal to stop and -restart transmission of output. + `EALREADY' + The socket SOCKET is non-blocking and already has a pending + connection in progress (see `EINPROGRESS' above). - "Clearing" the terminal input queue means discarding any characters -that have been received but not yet read. Similarly, clearing the -terminal output queue means discarding any characters that have been -written but not yet transmitted. + This function is defined as a cancellation point in multi-threaded + programs, so one has to be prepared for this and make sure that + allocated resources (like memory, files descriptors, semaphores or + whatever) are freed even if the thread is canceled.  -File: libc.info, Node: Canonical or Not, Next: Terminal Modes, Prev: I/O Queues, Up: Low-Level Terminal Interface +File: libc.info, Node: Listening, Next: Accepting Connections, Prev: Connecting, Up: Connections -Two Styles of Input: Canonical or Not -===================================== +Listening for Connections +------------------------- - POSIX systems support two basic modes of input: canonical and -noncanonical. + Now let us consider what the server process must do to accept +connections on a socket. First it must use the `listen' function to +enable connection requests on the socket, and then accept each incoming +connection with a call to `accept' (*note Accepting Connections::). +Once connection requests are enabled on a server socket, the `select' +function reports when the socket has a connection ready to be accepted +(*note Waiting for I/O::). - In "canonical input processing" mode, terminal input is processed in -lines terminated by newline (`'\n''), EOF, or EOL characters. No input -can be read until an entire line has been typed by the user, and the -`read' function (*note I/O Primitives::) returns at most a single line -of input, no matter how many bytes are requested. + The `listen' function is not allowed for sockets using +connectionless communication styles. - In canonical input mode, the operating system provides input editing -facilities: some characters are interpreted specially to perform editing -operations within the current line of text, such as ERASE and KILL. -*Note Editing Characters::. + You can write a network server that does not even start running +until a connection to it is requested. *Note Inetd Servers::. - The constants `_POSIX_MAX_CANON' and `MAX_CANON' parameterize the -maximum number of bytes which may appear in a single line of canonical -input. *Note Limits for Files::. You are guaranteed a maximum line -length of at least `MAX_CANON' bytes, but the maximum might be larger, -and might even dynamically change size. + In the Internet namespace, there are no special protection mechanisms +for controlling access to a port; any process on any machine can make a +connection to your server. If you want to restrict access to your +server, make it examine the addresses associated with connection +requests or implement some other handshaking or identification protocol. - In "noncanonical input processing" mode, characters are not grouped -into lines, and ERASE and KILL processing is not performed. The -granularity with which bytes are read in noncanonical input mode is -controlled by the MIN and TIME settings. *Note Noncanonical Input::. + In the local namespace, the ordinary file protection bits control +who has access to connect to the socket. - Most programs use canonical input mode, because this gives the user a -way to edit input line by line. The usual reason to use noncanonical -mode is when the program accepts single-character commands or provides -its own editing facilities. + - Function: int listen (int SOCKET, unsigned int N) + The `listen' function enables the socket SOCKET to accept + connections, thus making it a server socket. - The choice of canonical or noncanonical input is controlled by the -`ICANON' flag in the `c_lflag' member of `struct termios'. *Note Local -Modes::. + The argument N specifies the length of the queue for pending + connections. When the queue fills, new clients attempting to + connect fail with `ECONNREFUSED' until the server calls `accept' to + accept a connection from the queue. - -File: libc.info, Node: Terminal Modes, Next: BSD Terminal Modes, Prev: Canonical or Not, Up: Low-Level Terminal Interface + The `listen' function returns `0' on success and `-1' on failure. + The following `errno' error conditions are defined for this + function: -Terminal Modes -============== + `EBADF' + The argument SOCKET is not a valid file descriptor. - This section describes the various terminal attributes that control -how input and output are done.

Use the function `accept' to do +this. -Terminal Mode Data Types ------------------------- + A socket that has been established as a server can accept connection +requests from multiple clients. The server's original socket _does not +become part of the connection_; instead, `accept' makes a new socket +which participates in the connection. `accept' returns the descriptor +for this socket. The server's original socket remains available for +listening for further connection requests. - The entire collection of attributes of a terminal is stored in a -structure of type `struct termios'. This structure is used with the -functions `tcgetattr' and `tcsetattr' to read and set the attributes. + The number of pending connection requests on a server socket is +finite. If connection requests arrive from clients faster than the +server can act upon them, the queue can fill up and additional requests +are refused with an `ECONNREFUSED' error. You can specify the maximum +length of this queue as an argument to the `listen' function, although +the system may also impose its own internal limit on the length of this +queue. - - Data Type: struct termios - Structure that records all the I/O attributes of a terminal.

The new attributes are taken from the - structure that TERMIOS-P points to. + `ENOTCONN' + The socket SOCKET is not connected. - The WHEN argument specifies how to deal with input and output - already queued. It can be one of the following values: + `ENOBUFS' + There are not enough internal buffers available. - `TCSANOW' - Make the change immediately. + +File: libc.info, Node: Transferring Data, Next: Byte Stream Example, Prev: Who is Connected, Up: Connections - `TCSADRAIN' - Make the change after waiting until all queued output has - been written. You should usually use this option when - changing parameters that affect output. +Transferring Data +----------------- - `TCSAFLUSH' - This is like `TCSADRAIN', but also discards any queued input. + Once a socket has been connected to a peer, you can use the ordinary +`read' and `write' operations (*note I/O Primitives::) to transfer +data. A socket is a two-way communications channel, so read and write +operations can be performed at either end. - `TCSASOFT' - This is a flag bit that you can add to any of the above - alternatives. Its meaning is to inhibit alteration of the - state of the terminal hardware. It is a BSD extension; it is - only supported on BSD systems and the GNU system. + There are also some I/O modes that are specific to socket operations. +In order to specify these modes, you must use the `recv' and `send' +functions instead of the more generic `read' and `write' functions. +The `recv' and `send' functions take an additional argument which you +can use to specify various flags to control special I/O modes. For +example, you can specify the `MSG_OOB' flag to read or write +out-of-band data, the `MSG_PEEK' flag to peek at input, or the +`MSG_DONTROUTE' flag to control inclusion of routing information on +output. - Using `TCSASOFT' is exactly the same as setting the `CIGNORE' - bit in the `c_cflag' member of the structure TERMIOS-P points - to. *Note Control Modes::, for a description of `CIGNORE'. +* Menu: - If this function is called from a background process on its - controlling terminal, normally all processes in the process group - are sent a `SIGTTOU' signal, in the same way as if the process - were trying to write to the terminal.

If the socket was +connected but the connection has broken, you get a `SIGPIPE' signal for +any use of `send' or `write' (*note Miscellaneous Signals::). - `EINVAL' - Either the value of the `when' argument is not valid, or - there is something wrong with the data in the TERMIOS-P - argument. + - Function: int send (int SOCKET, void *BUFFER, size_t SIZE, int FLAGS) + The `send' function is like `write', but with the additional flags + FLAGS. The possible values of FLAGS are described in *Note Socket + Data Options::. - Although `tcgetattr' and `tcsetattr' specify the terminal device -with a file descriptor, the attributes are those of the terminal device -itself and not of the file descriptor. This means that the effects of -changing terminal attributes are persistent; if another process opens -the terminal file later on, it will see the changed attributes even -though it doesn't have anything to do with the open file descriptor you -originally specified in changing the attributes. + This function returns the number of bytes transmitted, or `-1' on + failure. If the socket is nonblocking, then `send' (like `write') + can return after sending just part of the data. *Note File Status + Flags::, for information about nonblocking mode. - Similarly, if a single process has multiple or duplicated file -descriptors for the same terminal device, changing the terminal -attributes affects input and output to all of these file descriptors. -This means, for example, that you can't open one file descriptor or -stream to read from a terminal in the normal line-buffered, echoed -mode; and simultaneously have another file descriptor for the same -terminal that you use to read from it in single-character, non-echoed -mode. Instead, you have to explicitly switch the terminal back and -forth between the two modes. + Note, however, that a successful return value merely indicates that + the message has been sent without error, not necessarily that it + has been received without error. - -File: libc.info, Node: Setting Modes, Next: Input Modes, Prev: Mode Functions, Up: Terminal Modes + The following `errno' error conditions are defined for this + function: -Setting Terminal Modes Properly -------------------------------- + `EBADF' + The SOCKET argument is not a valid file descriptor. - When you set terminal modes, you should call `tcgetattr' first to -get the current modes of the particular terminal device, modify only -those modes that you are really interested in, and store the result with -`tcsetattr'. + `EINTR' + The operation was interrupted by a signal before any data was + sent. *Note Interrupted Primitives::. - It's a bad idea to simply initialize a `struct termios' structure to -a chosen set of attributes and pass it directly to `tcsetattr'.

Don't try to specify -the entire value for `c_cflag'--instead, change only specific flags and -leave the rest untouched (*note Setting Modes::). + Streams with connections permit "out-of-band" data that is delivered +with higher priority than ordinary data. Typically the reason for +sending out-of-band data is to send notice of an exceptional condition. +To send out-of-band data use `send', specifying the flag `MSG_OOB' +(*note Sending Data::). - - Macro: tcflag_t CLOCAL - If this bit is set, it indicates that the terminal is connected - "locally" and that the modem status lines (such as carrier detect) - should be ignored. + Out-of-band data are received with higher priority because the +receiving process need not read it in sequence; to read the next +available out-of-band data, use `recv' with the `MSG_OOB' flag (*note +Receiving Data::). Ordinary read operations do not read out-of-band +data; they read only ordinary data. - On many systems if this bit is not set and you call `open' without - the `O_NONBLOCK' flag set, `open' blocks until a modem connection - is established. + When a socket finds that out-of-band data are on their way, it sends +a `SIGURG' signal to the owner process or process group of the socket. +You can specify the owner using the `F_SETOWN' command to the `fcntl' +function; see *Note Interrupt Input::. You must also establish a +handler for this signal, as described in *Note Signal Handling::, in +order to take appropriate action such as reading the out-of-band data. - If this bit is not set and a modem disconnect is detected, a - `SIGHUP' signal is sent to the controlling process group for the - terminal (if it has one). Normally, this causes the process to - exit; see *Note Signal Handling::. Reading from the terminal - after a disconnect causes an end-of-file condition, and writing - causes an `EIO' error to be returned. The terminal device must be - closed and reopened to clear the condition. + Alternatively, you can test for pending out-of-band data, or wait +until there is out-of-band data, using the `select' function; it can +wait for an exceptional condition on the socket. *Note Waiting for +I/O::, for more information about `select'. - - Macro: tcflag_t HUPCL - If this bit is set, a modem disconnect is generated when all - processes that have the terminal device open have either closed - the file or exited. + Notification of out-of-band data (whether with `SIGURG' or with +`select') indicates that out-of-band data are on the way; the data may +not actually arrive until later. If you try to read the out-of-band +data before it arrives, `recv' fails with an `EWOULDBLOCK' error. - - Macro: tcflag_t CREAD - If this bit is set, input can be read from the terminal. - Otherwise, input is discarded when it arrives. + Sending out-of-band data automatically places a "mark" in the stream +of ordinary data, showing where in the sequence the out-of-band data +"would have been". This is useful when the meaning of out-of-band data +is "cancel everything sent so far". Here is how you can test, in the +receiving process, whether any ordinary data was sent before the mark: - - Macro: tcflag_t CSTOPB - If this bit is set, two stop bits are used.

You can use the `CSIZE' macro as a mask to extract the -value, like this: `settings.c_cflag & CSIZE'. + If you don't want to discard the ordinary data preceding the mark, +you may need to read some of it anyway, to make room in internal system +buffers for the out-of-band data.

Otherwise, the character erased is re-echoed to - show what has happened (suitable for a printing terminal). +Receiving Datagrams +------------------- - This bit only controls the display behavior; the `ICANON' bit by - itself controls actual recognition of the ERASE character and - erasure of input, without which `ECHOE' is simply irrelevant. + The `recvfrom' function reads a packet from a datagram socket and +also tells you where it was sent from.

When you type the - ERASE character, a `\' character is printed followed by the first - character erased. Typing the ERASE character again just prints - the next character erased. Then, the next time you type a normal - character, a `/' character is printed before the character echoes. + - Function: int recvfrom (int SOCKET, void *BUFFER, size_t SIZE, int + FLAGS, struct sockaddr *ADDR, socklen_t *LENGTH-PTR) + The `recvfrom' function reads one packet from the socket SOCKET + into the buffer BUFFER. The SIZE argument specifies the maximum + number of bytes to be read. - This is a BSD extension, and exists only in BSD systems and the - GNU system. + If the packet is longer than SIZE bytes, then you get the first + SIZE bytes of the packet and the rest of the packet is lost. + There's no way to read the rest of the packet. Thus, when you use + a packet protocol, you must always know how long a packet to + expect. - - Macro: tcflag_t ECHOK - This bit enables special display of the KILL character by moving - to a new line after echoing the KILL character normally. The - behavior of `ECHOKE' (below) is nicer to look at. + The ADDR and LENGTH-PTR arguments are used to return the address + where the packet came from. *Note Socket Addresses::. For a + socket in the local domain the address information won't be + meaningful, since you can't read the address of such a socket + (*note Local Namespace::). You can specify a null pointer as the + ADDR argument if you are not interested in this information. - If this bit is not set, the KILL character echoes just as it would - if it were not the KILL character. Then it is up to the user to - remember that the KILL character has erased the preceding input; - there is no indication of this on the screen. + The FLAGS are interpreted the same way as for `recv' (*note Socket + Data Options::).

It enables special display of the - KILL character by erasing on the screen the entire line that has - been killed. This is a BSD extension, and exists only in BSD - systems and the GNU system. + You can use plain `recv' (*note Receiving Data::) instead of +`recvfrom' if you don't need to find out who sent the packet (either +because you know where it should come from or because you treat all +possible senders alike). Even `read' can be used if you don't want to +specify FLAGS (*note I/O Primitives::). - - Macro: tcflag_t ECHONL - If this bit is set and the `ICANON' bit is also set, then the - newline (`'\n'') character is echoed even if the `ECHO' bit is not - set. + +File: libc.info, Node: Datagram Example, Next: Example Receiver, Prev: Receiving Datagrams, Up: Datagrams - - Macro: tcflag_t ECHOCTL - If this bit is set and the `ECHO' bit is also set, echo control - characters with `^' followed by the corresponding text character. - Thus, control-A echoes as `^A'.

Each +time someone requests a connection to the appropriate port, a new server +process starts. The connection already exists at this time; the socket +is available as the standard input descriptor and as the standard +output descriptor (descriptors 0 and 1) in the server process. Thus +the server program can begin reading and writing data right away. +Often the program needs only the ordinary I/O facilities; in fact, a +general-purpose filter program that knows nothing about sockets can +work as a byte stream server run by `inetd'. - If the terminal is connected to a real serial line, the terminal -speed you specify actually controls the line--if it doesn't match the -terminal's own idea of the speed, communication does not work. Real -serial ports accept only certain standard speeds. Also, particular -hardware may not support even all the standard speeds. Specifying a -speed of zero hangs up a dialup connection and turns off modem control -signals. + You can also use `inetd' for servers that use connectionless +communication styles. For these servers, `inetd' does not try to accept +a connection since no connection is possible. It just starts the +server program, which can read the incoming datagram packet from +descriptor 0. The server program can handle one request and then exit, +or you can choose to write it to keep reading more requests until no +more arrive, and then exit. You must specify which of these two +techniques the server uses when you configure `inetd'. - If the terminal is not a real serial line (for example, if it is a -network connection), then the line speed won't really affect data -transmission speed, but some programs will use it to determine the -amount of padding needed. It's best to specify a line speed value that -matches the actual speed of the actual terminal, but you can safely -experiment with different values to vary the amount of padding. + +File: libc.info, Node: Configuring Inetd, Prev: Inetd Servers, Up: Inetd - There are actually two line speeds for each terminal, one for input -and one for output. You can set them independently, but most often -terminals use the same speed for both directions. +Configuring `inetd' +------------------- - The speed values are stored in the `struct termios' structure, but -don't try to access them in the `struct termios' structure directly. -Instead, you should use the following functions to read and store them: + The file `/etc/inetd.conf' tells `inetd' which ports to listen to +and what server programs to run for them.

The normal return value is 0; a value of -1 - indicates an error. If SPEED is not a speed, `cfsetspeed' returns - -1. This function is an extension in 4.4 BSD. + The SERVICE field says which service this program provides. It +should be the name of a service defined in `/etc/services'. `inetd' +uses SERVICE to decide which port to listen on for this entry. - - Data Type: speed_t - The `speed_t' type is an unsigned integer data type used to - represent line speeds. + The fields STYLE and PROTOCOL specify the communication style and +the protocol to use for the listening socket. The style should be the +name of a communication style, converted to lower case and with `SOCK_' +deleted--for example, `stream' or `dgram'. PROTOCOL should be one of +the protocols listed in `/etc/protocols'. The typical protocol names +are `tcp' for byte stream connections and `udp' for unreliable +datagrams. - The functions `cfsetospeed' and `cfsetispeed' report errors only for -speed values that the system simply cannot handle. If you specify a -speed value that is basically acceptable, then those functions will -succeed. But they do not check that a particular hardware device can -actually support the specified speeds--in fact, they don't know which -device you plan to set the speed for. If you use `tcsetattr' to set -the speed of a particular device to a value that it cannot handle, -`tcsetattr' returns -1. + The WAIT field should be either `wait' or `nowait'. Use `wait' if +STYLE is a connectionless style and the server, once started, handles +multiple requests as they come in. Use `nowait' if `inetd' should +start a new process for each message or request that comes in. If +STYLE uses connections, then WAIT *must* be `nowait'. - *Portability note:* In the GNU library, the functions above accept -speeds measured in bits per second as input, and return speed values -measured in bits per second. Other libraries require speeds to be -indicated by special codes. For POSIX.1 portability, you must use one -of the following symbols to represent the speed; their precise numeric -values are system-dependent, but each name has a fixed meaning: `B110' -stands for 110 bps, `B300' for 300 bps, and so on. There is no -portable way to represent any speed but these, but these are the only -speeds that typical serial lines can support. + USER is the user name that the server should run as. `inetd' runs +as root, so it can set the user ID of its children arbitrarily. It's +best to avoid using `root' for USER if you can; but some servers, such +as Telnet and FTP, read a username and password themselves.

The system facilities for the user to edit -input are disabled in noncanonical mode, so that all input characters -(unless they are special for signal or flow-control purposes) are passed -to the application program exactly as typed. It is up to the -application program to give the user ways to edit the input, if -appropriate. - - Noncanonical mode offers special parameters called MIN and TIME for -controlling whether and how long to wait for input to be available. You -can even use them to avoid ever waiting--to return immediately with -whatever input is available, or with no input. - - The MIN and TIME are stored in elements of the `c_cc' array, which -is a member of the `struct termios' structure. Each element of this -array has a particular role, and each element has a symbolic constant -that stands for the index of that element. `VMIN' and `VMAX' are the -names for the indices in the array of the MIN and TIME slots. +File: libc.info, Node: Is It a Terminal, Next: I/O Queues, Up: Low-Level Terminal Interface - - Macro: int VMIN - This is the subscript for the MIN slot in the `c_cc' array.

You can find out whether a file +descriptor is associated with a terminal by using the `isatty' function. - - Macro: int VTIME - This is the subscript for the TIME slot in the `c_cc' array. Thus, - `TERMIOS.c_cc[VTIME]' is the value itself. + Prototypes for the functions in this section are declared in the +header file `unistd.h'. - The TIME slot is only meaningful in noncanonical input mode; it - specifies how long to wait for input before returning, in units of - 0.1 seconds. + - Function: int isatty (int FILEDES) + This function returns `1' if FILEDES is a file descriptor + associated with an open terminal device, and 0 otherwise. - The MIN and TIME values interact to determine the criterion for when -`read' should return; their precise meanings depend on which of them -are nonzero. There are four possible cases: + If a file descriptor is associated with a terminal, you can get its +associated file name using the `ttyname' function. See also the +`ctermid' function, described in *Note Identifying the Terminal::. - * Both TIME and MIN are nonzero. + - Function: char * ttyname (int FILEDES) + If the file descriptor FILEDES is associated with a terminal + device, the `ttyname' function returns a pointer to a + statically-allocated, null-terminated string containing the file + name of the terminal file. The value is a null pointer if the + file descriptor isn't associated with a terminal, or the file name + cannot be determined. - In this case, TIME specifies how long to wait after each input - character to see if more input arrives. After the first character - received, `read' keeps waiting until either MIN bytes have arrived - in all, or TIME elapses with no further input. + - Function: int ttyname_r (int FILEDES, char *BUF, size_t LEN) + The `ttyname_r' function is similar to the `ttyname' function + except that it places its result into the user-specified buffer + starting at BUF with length LEN. - `read' always blocks until the first character arrives, even if - TIME elapses first. `read' can return more than MIN characters if - more than MIN happen to be in the queue. + The normal return value from `ttyname_r' is 0. Otherwise an error + number is returned to indicate the error. The following `errno' + error conditions are defined for this function: - * Both MIN and TIME are zero. + `EBADF' + The FILEDES argument is not a valid file descriptor. - In this case, `read' always returns immediately with as many - characters as are available in the queue, up to the number - requested. If no input is immediately available, `read' returns a - value of zero. + `ENOTTY' + The FILEDES is not associated with a terminal. - * MIN is zero but TIME has a nonzero value. + `ERANGE' + The buffer length LEN is too small to store the string to be + returned. - In this case, `read' waits for time TIME for input to become - available; the availability of a single byte is enough to satisfy - the read request and cause `read' to return. When it returns, it - returns as many characters as are available, up to the number - requested. If no input is available before the timer expires, - `read' returns a value of zero. + +File: libc.info, Node: I/O Queues, Next: Canonical or Not, Prev: Is It a Terminal, Up: Low-Level Terminal Interface - * TIME is zero but MIN has a nonzero value. +I/O Queues +========== - In this case, `read' waits until at least MIN bytes are available - in the queue. At that time, `read' returns as many characters as - are available, up to the number requested. `read' can return more - than MIN characters if more than MIN happen to be in the queue. + Many of the remaining functions in this section refer to the input +and output queues of a terminal device. These queues implement a form +of buffering _within the kernel_ independent of the buffering +implemented by I/O streams (*note I/O on Streams::). - What happens if MIN is 50 and you ask to read just 10 bytes? -Normally, `read' waits until there are 50 bytes in the buffer (or, more -generally, the wait condition described above is satisfied), and then -reads 10 of them, leaving the other 40 buffered in the operating system -for a subsequent call to `read'. + The "terminal input queue" is also sometimes referred to as its +"typeahead buffer". It holds the characters that have been received +from the terminal but not yet read by any process. - *Portability note:* On some systems, the MIN and TIME slots are -actually the same as the EOF and EOL slots. This causes no serious -problem because the MIN and TIME slots are used only in noncanonical -input and the EOF and EOL slots are used only in canonical input, but it -isn't very clean. The GNU library allocates separate slots for these -uses. + The size of the input queue is described by the `MAX_INPUT' and +`_POSIX_MAX_INPUT' parameters; see *Note Limits for Files::. You are +guaranteed a queue size of at least `MAX_INPUT', but the queue might be +larger, and might even dynamically change size. If input flow control +is enabled by setting the `IXOFF' input mode bit (*note Input Modes::), +the terminal driver transmits STOP and START characters to the terminal +when necessary to prevent the queue from overflowing. Otherwise, input +may be lost if it comes in too fast from the terminal. In canonical +mode, all input stays in the queue until a newline character is +received, so the terminal input queue can fill up when you type a very +long line. *Note Canonical or Not::. - - Function: int cfmakeraw (struct termios *TERMIOS-P) - This function provides an easy way to set up `*TERMIOS-P' for what - has traditionally been called "raw mode" in BSD. This uses - noncanonical input, and turns off most processing to give an - unmodified channel to the terminal. + The "terminal output queue" is like the input queue, but for output; +it contains characters that have been written by processes, but not yet +transmitted to the terminal. If output flow control is enabled by +setting the `IXON' input mode bit (*note Input Modes::), the terminal +driver obeys START and STOP characters sent by the terminal to stop and +restart transmission of output. - It does exactly this: - TERMIOS-P->c_iflag &= ~(IGNBRK|BRKINT|PARMRK|ISTRIP - |INLCR|IGNCR|ICRNL|IXON); - TERMIOS-P->c_oflag &= ~OPOST; - TERMIOS-P->c_lflag &= ~(ECHO|ECHONL|ICANON|ISIG|IEXTEN); - TERMIOS-P->c_cflag &= ~(CSIZE|PARENB); - TERMIOS-P->c_cflag |= CS8; + "Clearing" the terminal input queue means discarding any characters +that have been received but not yet read.

A DNS server might report usage statistics at regular intervals. +Input Modes +----------- - Some of these messages need to be brought to a system administrator's -attention immediately.

Still others may need to have -information extracted from them by an automated process that generates -monthly reports. + This section describes the terminal attribute flags that control +fairly low-level aspects of input processing: handling of parity errors, +break signals, flow control, and and characters. - To deal with these messages, most Unix systems have a facility called -"Syslog." It is generally based on a daemon called "Syslogd" Syslogd -listens for messages on a Unix domain socket named `/dev/log'. Based -on classification information in the messages and its configuration -file (usually `/etc/syslog.conf'), Syslogd routes them in various ways. -Some of the popular routings are: + All of these flags are bits in the `c_iflag' member of the `struct +termios' structure. The member is an integer, and you change flags +using the operators `&', `|' and `^'. Don't try to specify the entire +value for `c_iflag'--instead, change only specific flags and leave the +rest untouched (*note Setting Modes::). - * Write to the system console + - Macro: tcflag_t INPCK + If this bit is set, input parity checking is enabled.

For example, you + could clear the `INPCK' input mode flag and set the `PARENB' + control mode flag to ignore parity errors on input, but still + generate parity on output. - * Write to a log file + If this bit is set, what happens when a parity error is detected + depends on whether the `IGNPAR' or `PARMRK' bits are set. If + neither of these bits are set, a byte with a parity error is + passed to the application as a `'\0'' character. - * Pass to another daemon + - Macro: tcflag_t IGNPAR + If this bit is set, any byte with a framing or parity error is + ignored. This is only useful if `INPCK' is also set. - * Discard + - Macro: tcflag_t PARMRK + If this bit is set, input bytes with parity or framing errors are + marked when passed to the program. This bit is meaningful only + when `INPCK' is set and `IGNPAR' is not set. - Syslogd can also handle messages from other systems. It listens on -the `syslog' UDP port as well as the local socket for messages. + The way erroneous bytes are marked is with two preceding bytes, + `377' and `0'. Thus, the program actually reads three bytes for + one erroneous byte received from the terminal. - Syslog can handle messages from the kernel itself. But the kernel -doesn't write to `/dev/log'; rather, another daemon (sometimes called -"Klogd") extracts messages from the kernel and passes them on to Syslog -as any other process would (and it properly identifies them as messages -from the kernel). + If a valid byte has the value `0377', and `ISTRIP' (see below) is + not set, the program might confuse it with the prefix that marks a + parity error. So a valid byte `0377' is passed to the program as + two bytes, `0377' `0377', in this case. - Syslog can even handle messages that the kernel issued before -Syslogd or Klogd was running. A Linux kernel, for example, stores -startup messages in a kernel message ring and they are normally still -there when Klogd later starts up. Assuming Syslogd is running by the -time Klogd starts, Klogd then passes everything in the message ring to -it. + - Macro: tcflag_t ISTRIP + If this bit is set, valid input bytes are stripped to seven bits; + otherwise, all eight bits are available for programs to read. - In order to classify messages for disposition, Syslog requires any -process that submits a message to it to provide two pieces of -classification information with it: + - Macro: tcflag_t IGNBRK + If this bit is set, break conditions are ignored. -facility - This identifies who submitted the message.

Keep in mind that these - are essentially arbitrary classifications. "Mail subsystem" - doesn't have any more meaning than the system administrator gives - to it. + A "break condition" is defined in the context of asynchronous + serial data transmission as a series of zero-value bits longer + than a single byte. -priority - This tells how important the content of the message is. Examples - of defined priority values are: debug, informational, warning, - critical. For the complete list, *Note syslog; vsyslog::. Except - for the fact that the priorities have a defined order, the meaning - of each of these priorities is entirely determined by the system - administrator. + - Macro: tcflag_t BRKINT + If this bit is set and `IGNBRK' is not set, a break condition + clears the terminal input and output queues and raises a `SIGINT' + signal for the foreground process group associated with the + terminal. - A "facility/priority" is a number that indicates both the facility -and the priority. + If neither `BRKINT' nor `IGNBRK' are set, a break condition is + passed to the application as a single `'\0'' character if `PARMRK' + is not set, or otherwise as a three-character sequence `'\377'', + `'\0'', `'\0''. - *Warning:* This terminology is not universal. Some people use -"level" to refer to the priority and "priority" to refer to the -combination of facility and priority. A Linux kernel has a concept of a -message "level," which corresponds both to a Syslog priority and to a -Syslog facility/priority (It can be both because the facility code for -the kernel is zero, and that makes priority and facility/priority the -same value). + - Macro: tcflag_t IGNCR + If this bit is set, carriage return characters (`'\r'') are + discarded on input.

The numbers generated are not truly random; -typically, they form a sequence that repeats periodically, with a period -so large that you can ignore it for ordinary purposes. The random -number generator works by remembering a "seed" value which it uses to -compute the next random number and also to compute a new seed. - - Although the generated numbers look unpredictable within one run of a -program, the sequence of numbers is _exactly the same_ from one run to -the next. This is because the initial seed is always the same. This -is convenient when you are debugging a program, but it is unhelpful if -you want the program to behave unpredictably. If you want a different -pseudo-random series each time your program runs, you must specify a -different seed each time. For ordinary purposes, basing the seed on the -current time works well. - - You can obtain repeatable sequences of numbers on a particular -machine type by specifying the same initial seed value for the random -number generator. There is no standard meaning for a particular seed -value; the same seed, used in different C libraries or on different CPU -types, will give you different random numbers. - - The GNU library supports the standard ISO C random number functions -plus two other sets derived from BSD and SVID. The BSD and ISO C -functions provide identical, somewhat limited functionality. If only a -small number of random bits are required, we recommend you use the -ISO C interface, `rand' and `srand'. The SVID functions provide a more -flexible interface, which allows better random number generator -algorithms, provides more random bits (up to 48) per call, and can -provide random floating-point numbers. These functions are required by -the XPG standard and therefore will be present in all modern Unix -systems. - -* Menu: - -* ISO Random:: `rand' and friends. -* BSD Random:: `random' and friends. -* SVID Random:: `drand48' and friends. - - -File: libc.info, Node: ISO Random, Next: BSD Random, Up: Pseudo-Random Numbers - -ISO C Random Number Functions ------------------------------ - - This section describes the random number functions that are part of -the ISO C standard. - - To use these facilities, you should include the header file -`stdlib.h' in your program. - - - Macro: int RAND_MAX - The value of this macro is an integer constant representing the - largest value the `rand' function can return.

The value ranges from `0' to `RAND_MAX'. - - - Function: void srand (unsigned int SEED) - This function establishes SEED as the seed for a new series of - pseudo-random numbers. If you call `rand' before a seed has been - established with `srand', it uses the value `1' as a default seed. - - To produce a different pseudo-random series each time your program - is run, do `srand (time (0))'. - - POSIX.1 extended the C standard functions to support reproducible -random numbers in multi-threaded programs. However, the extension is -badly designed and unsuitable for serious work. - - - Function: int rand_r (unsigned int *SEED) - This function returns a random number in the range 0 to `RAND_MAX' - just as `rand' does.

The value returned ranges from `0' to `RAND_MAX'. - - *Note:* Temporarily this function was defined to return a - `int32_t' value to indicate that the return value always contains - 32 bits even if `long int' is wider. The standard demands it - differently. Users must always be aware of the 32-bit limitation, - though. - - - Function: void srandom (unsigned int SEED) - The `srandom' function sets the state of the random number - generator based on the integer SEED. If you supply a SEED value - of `1', this will cause `random' to reproduce the default set of - random numbers. - - To produce a different set of pseudo-random numbers each time your - program runs, do `srandom (time (0))'. - - - Function: void * initstate (unsigned int SEED, void *STATE, size_t - SIZE) - The `initstate' function is used to initialize the random number - generator state. The argument STATE is an array of SIZE bytes, - used to hold the state information. It is initialized based on - SEED. The size must be between 8 and 256 bytes, and should be a - power of two.

You can use this value later as an argument to `setstate' - to restore that state. - - If the function fails the return value is `NULL'. - - The four functions described so far in this section all work on a -state which is shared by all threads. The state is not directly -accessible to the user and can only be modified by these functions. -This makes it hard to deal with situations where each thread should -have its own pseudo-random number generator. - - The GNU C library contains four additional functions which contain -the state as an explicit parameter and therefore make it possible to -handle thread-local PRNGs. Beside this there are no difference. In -fact, the four functions already discussed are implemented internally -using the following interfaces. - - The `stdlib.h' header contains a definition of the following type: - - - Data Type: struct random_data - Objects of type `struct random_data' contain the information - necessary to represent the state of the PRNG.

They use a state of 48 bits of data. The -user can choose among a collection of functions which return the random -bits in different forms. - - Generally there are two kinds of function. The first uses a state of -the random number generator which is shared among several functions and -by all threads of the process. The second requires the user to handle -the state. - - All functions have in common that they use the same congruential -formula with the same constants. The formula is - - Y = (a * X + c) mod m - -where X is the state of the generator at the beginning and Y the state -at the end. `a' and `c' are constants determining the way the -generator works. By default they are - - a = 0x5DEECE66D = 25214903917 - c = 0xb = 11 - -but they can also be changed by the user. `m' is of course 2^48 since -the state consists of a 48-bit array. - - The prototypes for these functions are in `stdlib.h'. - - - Function: double drand48 (void) - This function returns a `double' value in the range of `0.0' to - `1.0' (exclusive). The random bits are determined by the global - state of the random number generator in the C library. - - Since the `double' type according to IEEE 754 has a 52-bit - mantissa this means 4 bits are not initialized by the random number - generator. These are (of course) chosen to be the least - significant bits and they are initialized to `0'. - - - Function: double erand48 (unsigned short int XSUBI[3]) - This function returns a `double' value in the range of `0.0' to - `1.0' (exclusive), similarly to `drand48'. The argument is an - array describing the state of the random number generator. - - This function can be called subsequently since it updates the - array to guarantee random numbers. The array should have been - initialized before initial use to obtain reproducible results. - - - Function: long int lrand48 (void) - The `lrand48' function returns an integer value in the range of - `0' to `2^31' (exclusive). Even if the size of the `long int' - type can take more than 32 bits, no higher numbers are returned. - The random bits are determined by the global state of the random - number generator in the C library. - - - Function: long int nrand48 (unsigned short int XSUBI[3]) - This function is similar to the `lrand48' function in that it - returns a number in the range of `0' to `2^31' (exclusive) but the - state of the random number generator used to produce the random - bits is determined by the array provided as the parameter to the - function. - - The numbers in the array are updated afterwards so that subsequent - calls to this function yield different results (as is expected of - a random number generator). The array should have been - initialized before the first call to obtain reproducible results. - - - Function: long int mrand48 (void) - The `mrand48' function is similar to `lrand48'. The only - difference is that the numbers returned are in the range `-2^31' to - `2^31' (exclusive). - - - Function: long int jrand48 (unsigned short int XSUBI[3]) - The `jrand48' function is similar to `nrand48'. The only - difference is that the numbers returned are in the range `-2^31' to - `2^31' (exclusive). For the `xsubi' parameter the same - requirements are necessary. - - The internal state of the random number generator can be initialized -in several ways. The methods differ in the completeness of the -information provided. - - - Function: void srand48 (long int SEEDVAL) - The `srand48' function sets the most significant 32 bits of the - internal state of the random number generator to the least - significant 32 bits of the SEEDVAL parameter. The lower 16 bits - are initialized to the value `0x330E'. Even if the `long int' - type contains more than 32 bits only the lower 32 bits are used. - - Owing to this limitation, initialization of the state of this - function is not very useful. But it makes it easy to use a - construct like `srand48 (time (0))'. - - A side-effect of this function is that the values `a' and `c' from - the internal state, which are used in the congruential formula, - are reset to the default values given above. This is of - importance once the user has called the `lcong48' function (see - below). - - - Function: unsigned short int * seed48 (unsigned short int SEED16V[3]) - The `seed48' function initializes all 48 bits of the state of the - internal random number generator from the contents of the parameter - SEED16V. Here the lower 16 bits of the first element of SEE16V - initialize the least significant 16 bits of the internal state, - the lower 16 bits of `SEED16V[1]' initialize the mid-order 16 bits - of the state and the 16 lower bits of `SEED16V[2]' initialize the - most significant 16 bits of the state. - - Unlike `srand48' this function lets the user initialize all 48 bits - of the state. - - The value returned by `seed48' is a pointer to an array containing - the values of the internal state before the change. This might be - useful to restart the random number generator at a certain state. - Otherwise the value can simply be ignored. - - As for `srand48', the values `a' and `c' from the congruential - formula are reset to the default values. - - There is one more function to initialize the random number generator -which enables you to specify even more information by allowing you to -change the parameters in the congruential formula. - - - Function: void lcong48 (unsigned short int PARAM[7]) - The `lcong48' function allows the user to change the complete state - of the random number generator. Unlike `srand48' and `seed48', - this function also changes the constants in the congruential - formula. - - From the seven elements in the array PARAM the least significant - 16 bits of the entries `PARAM[0]' to `PARAM[2]' determine the - initial state, the least significant 16 bits of `PARAM[3]' to - `PARAM[5]' determine the 48 bit constant `a' and `PARAM[6]' - determines the 16-bit value `c'. - - All the above functions have in common that they use the global -parameters for the congruential formula. In multi-threaded programs it -might sometimes be useful to have different parameters in different -threads. For this reason all the above functions have a counterpart -which works on a description of the random number generator in the -user-supplied buffer instead of the global state. - - Please note that it is no problem if several threads use the global -state if all threads use the functions which take a pointer to an array -containing the state. The random numbers are computed following the -same loop but if the state in the array is different all threads will -obtain an individual random number generator. - - The user-supplied buffer must be of type `struct drand48_data'. -This type should be regarded as opaque and not manipulated directly. - - - Function: int drand48_r (struct drand48_data *BUFFER, double *RESULT) - This function is equivalent to the `drand48' function with the - difference that it does not modify the global random number - generator parameters but instead the parameters in the buffer - supplied through the pointer BUFFER. The random number is - returned in the variable pointed to by RESULT. - - The return value of the function indicates whether the call - succeeded. If the value is less than `0' an error occurred and - ERRNO is set to indicate the problem. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int erand48_r (unsigned short int XSUBI[3], struct - drand48_data *BUFFER, double *RESULT) - The `erand48_r' function works like `erand48', but in addition it - takes an argument BUFFER which describes the random number - generator. The state of the random number generator is taken from - the `xsubi' array, the parameters for the congruential formula - from the global random number generator data. The random number - is returned in the variable pointed to by RESULT. - - The return value is non-negative if the call succeeded. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int lrand48_r (struct drand48_data *BUFFER, double *RESULT) - This function is similar to `lrand48', but in addition it takes a - pointer to a buffer describing the state of the random number - generator just like `drand48'. - - If the return value of the function is non-negative the variable - pointed to by RESULT contains the result. Otherwise an error - occurred. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int nrand48_r (unsigned short int XSUBI[3], struct - drand48_data *BUFFER, long int *RESULT) - The `nrand48_r' function works like `nrand48' in that it produces - a random number in the range `0' to `2^31'. But instead of using - the global parameters for the congruential formula it uses the - information from the buffer pointed to by BUFFER. The state is - described by the values in XSUBI. - - If the return value is non-negative the variable pointed to by - RESULT contains the result. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int mrand48_r (struct drand48_data *BUFFER, double *RESULT) - This function is similar to `mrand48' but like the other reentrant - functions it uses the random number generator described by the - value in the buffer pointed to by BUFFER. - - If the return value is non-negative the variable pointed to by - RESULT contains the result. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int jrand48_r (unsigned short int XSUBI[3], struct - drand48_data *BUFFER, long int *RESULT) - The `jrand48_r' function is similar to `jrand48'. Like the other - reentrant functions of this function family it uses the - congruential formula parameters from the buffer pointed to by - BUFFER. - - If the return value is non-negative the variable pointed to by - RESULT contains the result. - - This function is a GNU extension and should not be used in portable - programs. - - Before any of the above functions are used the buffer of type -`struct drand48_data' should be initialized. The easiest way to do -this is to fill the whole buffer with null bytes, e.g. by - - memset (buffer, '\0', sizeof (struct drand48_data)); - -Using any of the reentrant functions of this family now will -automatically initialize the random number generator to the default -values for the state and the parameters of the congruential formula. - - The other possibility is to use any of the functions which explicitly -initialize the buffer. Though it might be obvious how to initialize the -buffer from looking at the parameter to the function, it is highly -recommended to use these functions since the result might not always be -what you expect. - - - Function: int srand48_r (long int SEEDVAL, struct drand48_data - *BUFFER) - The description of the random number generator represented by the - information in BUFFER is initialized similarly to what the function - `srand48' does. The state is initialized from the parameter - SEEDVAL and the parameters for the congruential formula are - initialized to their default values. - - If the return value is non-negative the function call succeeded. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int seed48_r (unsigned short int SEED16V[3], struct - drand48_data *BUFFER) - This function is similar to `srand48_r' but like `seed48' it - initializes all 48 bits of the state from the parameter SEED16V. - - If the return value is non-negative the function call succeeded. - It does not return a pointer to the previous state of the random - number generator like the `seed48' function does. If the user - wants to preserve the state for a later re-run s/he can copy the - whole buffer pointed to by BUFFER. - - This function is a GNU extension and should not be used in portable - programs. - - - Function: int lcong48_r (unsigned short int PARAM[7], struct - drand48_data *BUFFER) - This function initializes all aspects of the random number - generator described in BUFFER with the data in PARAM. Here it is - especially true that the function does more than just copying the - contents of PARAM and BUFFER. More work is required and therefore - it is important to use this function rather than initializing the - random number generator directly. - - If the return value is non-negative the function call succeeded. - - This function is a GNU extension and should not be used in portable - programs. - - -File: libc.info, Node: FP Function Optimizations, Prev: Pseudo-Random Numbers, Up: Mathematics - -Is Fast Code or Small Code preferred? -===================================== - - If an application uses many floating point functions it is often the -case that the cost of the function calls themselves is not negligible. -Modern processors can often execute the operations themselves very -fast, but the function call disrupts the instruction pipeline. - - For this reason the GNU C Library provides optimizations for many of -the frequently-used math functions.

These new functions and macros have the same names as the -library functions and so are used instead of the latter. In the case of -inline functions the compiler will decide whether it is reasonable to -use them, and this decision is usually correct. - - This means that no calls to the library functions may be necessary, -and can increase the speed of generated code significantly. The -drawback is that code size will increase, and the increase is not -always negligible. - - There are two kind of inline functions: Those that give the same -result as the library functions and others that might not set `errno' -and might have a reduced precision and/or argument range in comparison -with the library functions. The latter inline functions are only -available if the flag `-ffast-math' is given to GNU CC. - - In cases where the inline functions and macros are not wanted the -symbol `__NO_MATH_INLINES' should be defined before any system header is -included.

The GNU C compiler extends the language to contain long -long integers as well. - - The C integer types were intended to allow code to be portable among -machines with different inherent data sizes (word sizes), so each type -may have different ranges on different machines. The problem with this -is that a program often needs to be written for a particular range of -integers, and sometimes must be written for a particular size of -storage, regardless of what machine the program runs on. - - To address this problem, the GNU C library contains C type -definitions you can use to declare integers that meet your exact needs. -Because the GNU C library header files are customized to a specific -machine, your program source code doesn't have to be. - - These `typedef's are in `stdint.h'. - - If you require that an integer be represented in exactly N bits, use -one of the following types, with the obvious mapping to bit size and -signedness: - - * int8_t - - * int16_t - - * int32_t - - * int64_t - - * uint8_t - - * uint16_t - - * uint32_t - - * uint64_t - - If your C compiler and target machine do not allow integers of a -certain size, the corresponding above type does not exist. - - If you don't need a specific storage size, but want the smallest data -structure with _at least_ N bits, use one of these: - - * int_least8_t - - * int_least16_t - - * int_least32_t - - * int_least64_t - - * uint_least8_t - - * uint_least16_t - - * uint_least32_t - - * uint_least64_t - - If you don't need a specific storage size, but want the data -structure that allows the fastest access while having at least N bits -(and among data structures with the same access speed, the smallest -one), use one of these: - - * int_fast8_t - - * int_fast16_t - - * int_fast32_t - - * int_fast64_t - - * uint_fast8_t - - * uint_fast16_t - - * uint_fast32_t - - * uint_fast64_t - - If you want an integer with the widest range possible on the -platform on which it is being used, use one of the following.

Floating-point numbers have three parts: the "mantissa", the -"exponent", and the "sign bit". The real number represented by a -floating-point value is given by (s ? -1 : 1) * 2^e * M where s is the -sign bit, e the exponent, and M the mantissa. *Note Floating Point -Concepts::, for details.

The possible values are: - - `FP_NAN' - The floating-point number X is "Not a Number" (*note Infinity - and NaN::) - - `FP_INFINITE' - The value of X is either plus or minus infinity (*note - Infinity and NaN::) - - `FP_ZERO' - The value of X is zero. In floating-point formats like - IEEE 754, where zero can be signed, this value is also - returned if X is negative zero. - - `FP_SUBNORMAL' - Numbers whose absolute value is too small to be represented - in the normal format are represented in an alternate, - "denormalized" format (*note Floating Point Concepts::). - This format is less precise but can represent values closer - to zero. `fpclassify' returns this value for values of X in - this alternate format. - - `FP_NORMAL' - This value is returned for all other values of X. It - indicates that there is nothing special about the number. - - - `fpclassify' is most useful if more than one property of a number -must be tested.

Each corresponds to a particular sort of error, -such as overflow. - - When exceptions occur (when exceptions are "raised", in the language -of the standard), one of two things can happen. By default the -exception is simply noted in the floating-point "status word", and the -program continues as if nothing had happened. The operation produces a -default value, which depends on the exception (see the table below). -Your program can check the status word to find out which exceptions -happened. - - Alternatively, you can enable "traps" for exceptions. In that case, -when an exception is raised, your program will receive the `SIGFPE' -signal. The default action for this signal is to terminate the -program. *Note Signal Handling::, for how you can change the effect of -the signal. - - In the System V math library, the user-defined function `matherr' is -called when certain exceptions occur inside math library functions. -However, the Unix98 standard deprecates this interface. We support it -for historical compatibility, but recommend that you do not use it in -new programs. - -The exceptions defined in IEEE 754 are: - -`Invalid Operation' - This exception is raised if the given operands are invalid for the - operation to be performed. Examples are (see IEEE 754, section 7): - 1. Addition or subtraction: oo - oo. (But oo + oo = oo). - - 2. Multiplication: 0 * oo. - - 3. Division: 0/0 or oo/oo. - - 4. Remainder: x REM y, where y is zero or x is infinite. - - 5. Square root if the operand is less then zero. More - generally, any mathematical function evaluated outside its - domain produces this exception. - - 6. Conversion of a floating-point number to an integer or decimal - string, when the number cannot be represented in the target - format (due to overflow, infinity, or NaN). - - 7. Conversion of an unrecognizable input string. - - 8. Comparison via predicates involving < or >, when one or other - of the operands is NaN. You can prevent this exception by - using the unordered comparison functions instead; see *Note - FP Comparison Functions::. - - If the exception does not trap, the result of the operation is NaN. - -`Division by Zero' - This exception is raised when a finite nonzero number is divided - by zero. If no trap occurs the result is either +oo or -oo, - depending on the signs of the operands. - -`Overflow' - This exception is raised whenever the result cannot be represented - as a finite value in the precision format of the destination. If - no trap occurs the result depends on the sign of the intermediate - result and the current rounding mode (IEEE 754, section 7.3): - 1. Round to nearest carries all overflows to oo with the sign of - the intermediate result. - - 2. Round toward 0 carries all overflows to the largest - representable finite number with the sign of the intermediate - result. - - 3. Round toward -oo carries positive overflows to the largest - representable finite number and negative overflows to -oo. - - 4. Round toward oo carries negative overflows to the most - negative representable finite number and positive overflows - to oo. - - Whenever the overflow exception is raised, the inexact exception - is also raised. - -`Underflow' - The underflow exception is raised when an intermediate result is - too small to be calculated accurately, or if the operation's - result rounded to the destination precision is too small to be - normalized. - - When no trap is installed for the underflow exception, underflow is - signaled (via the underflow flag) only when both tininess and loss - of accuracy have been detected. If no trap handler is installed - the operation continues with an imprecise small value, or zero if - the destination precision cannot hold the small exact result. - -`Inexact' - This exception is signalled if a rounded result is not exact (such - as when calculating the square root of two) or a result overflows - without an overflow trap. - - -File: libc.info, Node: Infinity and NaN, Next: Status bit operations, Prev: FP Exceptions, Up: Floating Point Errors - -Infinity and NaN ----------------- - - IEEE 754 floating point numbers can represent positive or negative -infinity, and "NaN" (not a number). These three values arise from -calculations whose result is undefined or cannot be represented -accurately. You can also deliberately set a floating-point variable to -any of them, which is sometimes useful. Some examples of calculations -that produce infinity or NaN: - - 1/0 = oo - log (0) = -oo - sqrt (-1) = NaN - - When a calculation produces any of these values, an exception also -occurs; see *Note FP Exceptions::. - - The basic operations and math functions all accept infinity and NaN -and produce sensible output. Infinities propagate through calculations -as one would expect: for example, 2 + oo = oo, 4/oo = 0, atan (oo) = -pi/2. NaN, on the other hand, infects any calculation that involves -it. Unless the calculation would produce the same result no matter -what real value replaced NaN, the result is NaN. - - In comparison operations, positive infinity is larger than all values -except itself and NaN, and negative infinity is smaller than all values -except itself and NaN. NaN is "unordered": it is not equal to, greater -than, or less than anything, _including itself_. `x == x' is false if -the value of `x' is NaN. You can use this to test whether a value is -NaN or not, but the recommended way to test for NaN is with the `isnan' -function (*note Floating Point Classes::). In addition, `<', `>', -`<=', and `>=' will raise an exception when applied to NaNs. - - `math.h' defines macros that allow you to explicitly set a variable -to infinity or NaN. - - - Macro: float INFINITY - An expression representing positive infinity. It is equal to the - value produced by mathematical operations like `1.0 / 0.0'. - `-INFINITY' represents negative infinity. - - You can test whether a floating-point value is infinite by - comparing it to this macro. However, this is not recommended; you - should use the `isfinite' macro instead. *Note Floating Point - Classes::. - - This macro was introduced in the ISO C99 standard. - - - Macro: float NAN - An expression representing a value which is "not a number". This - macro is a GNU extension, available only on machines that support - the "not a number" value--that is to say, on all machines that - support IEEE floating point. - - You can use `#ifdef NAN' to test whether the machine supports NaN. - (Of course, you must arrange for GNU extensions to be visible, - such as by defining `_GNU_SOURCE', and then you must include - `math.h'.) - - IEEE 754 also allows for another unusual value: negative zero. This -value is produced when you divide a positive number by negative -infinity, or when a negative result is smaller than the limits of -representation. Negative zero behaves identically to zero in all -calculations, unless you explicitly test the sign bit with `signbit' or -`copysign'. - - -File: libc.info, Node: Status bit operations, Next: Math Error Reporting, Prev: Infinity and NaN, Up: Floating Point Errors - -Examining the FPU status word ------------------------------ - - ISO C99 defines functions to query and manipulate the floating-point -status word.

Ideally the error for all functions is always +less than 0.5ulps. Using rounding bits this is also possible and +normally implemented for the basic operations. To achieve the same for +the complex math functions requires a lot more work and this has not +yet been done. - - Function: int fegetexceptflag (fexcept_t *FLAGP, int EXCEPTS) - This function stores in the variable pointed to by FLAGP an - implementation-defined value representing the current setting of - the exception flags indicated by EXCEPTS. + Therefore many of the functions in the math library have errors. The +table lists the maximum error for each function which is exposed by one +of the existing tests in the test suite. The table tries to cover as +much as possible and list the actual maximum error (or at least a +ballpark figure) but this is often not achieved due to the large search +space. - The function returns zero in case the operation was successful, a - non-zero value otherwise. + The table lists the ULP values for different architectures. +Different architectures have different results since their hardware +support for floating-point operations varies and also the existing +hardware support is different. - - Function: int fesetexceptflag (const fexcept_t *FLAGP, int - EXCEPTS) This function restores the flags for the exceptions - indicated by EXCEPTS to the values stored in the variable pointed - to by FLAGP. +Function Alpha ARM Generic ix86 IA64 +acosf -

Even if they are mathematically defined, -their result may be larger or smaller than the range representable by -their return type. These are known as "domain errors", "overflows", and -"underflows", respectively. Math functions do several things when one -of these errors occurs. In this manual we will refer to the complete -response as "signalling" a domain error, overflow, or underflow. + This section describes the GNU facilities for generating a series of +pseudo-random numbers. The numbers generated are not truly random; +typically, they form a sequence that repeats periodically, with a period +so large that you can ignore it for ordinary purposes. The random +number generator works by remembering a "seed" value which it uses to +compute the next random number and also to compute a new seed. - When a math function suffers a domain error, it raises the invalid -exception and returns NaN. It also sets ERRNO to `EDOM'; this is for -compatibility with old systems that do not support IEEE 754 exception -handling. Likewise, when overflow occurs, math functions raise the -overflow exception and return oo or -oo as appropriate. They also set -ERRNO to `ERANGE'. When underflow occurs, the underflow exception is -raised, and zero (appropriately signed) is returned. ERRNO may be set -to `ERANGE', but this is not guaranteed. + Although the generated numbers look unpredictable within one run of a +program, the sequence of numbers is _exactly the same_ from one run to +the next. This is because the initial seed is always the same. This +is convenient when you are debugging a program, but it is unhelpful if +you want the program to behave unpredictably. If you want a different +pseudo-random series each time your program runs, you must specify a +different seed each time. For ordinary purposes, basing the seed on the +current time works well. - Some of the math functions are defined mathematically to result in a -complex value over parts of their domains. The most familiar example of -this is taking the square root of a negative number. The complex math -functions, such as `csqrt', will return the appropriate complex value -in this case. The real-valued functions, such as `sqrt', will signal a -domain error. + You can obtain repeatable sequences of numbers on a particular +machine type by specifying the same initial seed value for the random +number generator. There is no standard meaning for a particular seed +value; the same seed, used in different C libraries or on different CPU +types, will give you different random numbers. - Some older hardware does not support infinities. On that hardware, -overflows instead return a particular very large number (usually the -largest representable number). `math.h' defines macros you can use to -test for overflow on both old and new hardware. + The GNU library supports the standard ISO C random number functions +plus two other sets derived from BSD and SVID. The BSD and ISO C +functions provide identical, somewhat limited functionality. If only a +small number of random bits are required, we recommend you use the +ISO C interface, `rand' and `srand'. The SVID functions provide a more +flexible interface, which allows better random number generator +algorithms, provides more random bits (up to 48) per call, and can +provide random floating-point numbers. These functions are required by +the XPG standard and therefore will be present in all modern Unix +systems. - - Macro: double HUGE_VAL - - Macro: float HUGE_VALF - - Macro: long double HUGE_VALL - An expression representing a particular very large number.

This -ensures that results are as precise as the input data. IEEE 754 -defines four possible rounding modes: + This section describes the random number functions that are part of +the ISO C standard. -Round to nearest. - This is the default mode. It should be used unless there is a - specific need for one of the others. In this mode results are - rounded to the nearest representable value. If the result is - midway between two representable values, the even representable is - chosen. "Even" here means the lowest-order bit is zero. This - rounding mode prevents statistical bias and guarantees numeric - stability: round-off errors in a lengthy calculation will remain - smaller than half of `FLT_EPSILON'. + To use these facilities, you should include the header file +`stdlib.h' in your program. -Round toward plus Infinity. - All results are rounded to the smallest representable value which - is greater than the result. + - Macro: int RAND_MAX + The value of this macro is an integer constant representing the + largest value the `rand' function can return. In the GNU library, + it is `2147483647', which is the largest signed integer + representable in 32 bits. In other libraries, it may be as low as + `32767'. -Round toward minus Infinity. - All results are rounded to the largest representable value which - is less than the result. + - Function: int rand (void) + The `rand' function returns the next pseudo-random number in the + series. The value ranges from `0' to `RAND_MAX'. -Round toward zero. - All results are rounded to the largest representable value whose - magnitude is less than that of the result. In other words, if the - result is negative it is rounded up; if it is positive, it is - rounded down. + - Function: void srand (unsigned int SEED) + This function establishes SEED as the seed for a new series of + pseudo-random numbers. If you call `rand' before a seed has been + established with `srand', it uses the value `1' as a default seed. -`fenv.h' defines constants which you can use to refer to the various -rounding modes. Each one will be defined if and only if the FPU -supports the corresponding rounding mode. + To produce a different pseudo-random series each time your program + is run, do `srand (time (0))'. -`FE_TONEAREST' - Round to nearest. + POSIX.1 extended the C standard functions to support reproducible +random numbers in multi-threaded programs. However, the extension is +badly designed and unsuitable for serious work. -`FE_UPWARD' - Round toward +oo. + - Function: int rand_r (unsigned int *SEED) + This function returns a random number in the range 0 to `RAND_MAX' + just as `rand' does. However, all its state is stored in the SEED + argument. This means the RNG's state can only have as many bits + as the type `unsigned int' has. This is far too few to provide a + good RNG. -`FE_DOWNWARD' - Round toward -oo. + If your program requires a reentrant RNG, we recommend you use the + reentrant GNU extensions to the SVID random number generator. The + POSIX.1 interface should only be used when the GNU extensions are + not available. -`FE_TOWARDZERO' - Round toward zero. + +File: libc.info, Node: BSD Random, Next: SVID Random, Prev: ISO Random, Up: Pseudo-Random Numbers - Underflow is an unusual case. Normally, IEEE 754 floating point -numbers are always normalized (*note Floating Point Concepts::). -Numbers smaller than 2^r (where r is the minimum exponent, -`FLT_MIN_RADIX-1' for FLOAT) cannot be represented as normalized -numbers. Rounding all such numbers to zero or 2^r would cause some -algorithms to fail at 0. Therefore, they are left in denormalized -form. That produces loss of precision, since some bits of the mantissa -are stolen to indicate the decimal point. +BSD Random Number Functions +--------------------------- - If a result is too small to be represented as a denormalized number, -it is rounded to zero. However, the sign of the result is preserved; if -the calculation was negative, the result is "negative zero". Negative -zero can also result from some operations on infinity, such as 4/-oo. -Negative zero behaves identically to zero except when the `copysign' or -`signbit' functions are used to check the sign bit directly. + This section describes a set of random number generation functions +that are derived from BSD. There is no advantage to using these +functions with the GNU C library; we support them for BSD compatibility +only. - At any time one of the above four rounding modes is selected. You -can find out which one with this function: + The prototypes for these functions are in `stdlib.h'. - - Function: int fegetround (void) - Returns the currently selected rounding mode, represented by one - of the values of the defined rounding mode macros. + - Function: long int random (void) + This function returns the next pseudo-random number in the + sequence. The value returned ranges from `0' to `RAND_MAX'. -To change the rounding mode, use this function: + *Note:* Temporarily this function was defined to return a + `int32_t' value to indicate that the return value always contains + 32 bits even if `long int' is wider. The standard demands it + differently. Users must always be aware of the 32-bit limitation, + though. - - Function: int fesetround (int ROUND) - Changes the currently selected rounding mode to ROUND. If ROUND - does not correspond to one of the supported rounding modes nothing - is changed. `fesetround' returns zero if it changed the rounding - mode, a nonzero value if the mode is not supported. + - Function: void srandom (unsigned int SEED) + The `srandom' function sets the state of the random number + generator based on the integer SEED. If you supply a SEED value + of `1', this will cause `random' to reproduce the default set of + random numbers. - You should avoid changing the rounding mode if possible. It can be -an expensive operation; also, some hardware requires you to compile your -program differently for it to work. The resulting code may run slower. -See your compiler documentation for details. + To produce a different set of pseudo-random numbers each time your + program runs, do `srandom (time (0))'. + + - Function: void * initstate (unsigned int SEED, void *STATE, size_t + SIZE) + The `initstate' function is used to initialize the random number + generator state. The argument STATE is an array of SIZE bytes, + used to hold the state information. It is initialized based on + SEED. The size must be between 8 and 256 bytes, and should be a + power of two. The bigger the STATE array, the better. + + The return value is the previous value of the state information + array. You can use this value later as an argument to `setstate' + to restore that state. + + - Function: void * setstate (void *STATE) + The `setstate' function restores the random number state + information STATE. The argument must have been the result of a + previous call to INITSTATE or SETSTATE. + + The return value is the previous value of the state information + array. You can use this value later as an argument to `setstate' + to restore that state. + + If the function fails the return value is `NULL'. + + The four functions described so far in this section all work on a +state which is shared by all threads. The state is not directly +accessible to the user and can only be modified by these functions. +This makes it hard to deal with situations where each thread should +have its own pseudo-random number generator. + + The GNU C library contains four additional functions which contain +the state as an explicit parameter and therefore make it possible to +handle thread-local PRNGs. Beside this there are no difference. In +fact, the four functions already discussed are implemented internally +using the following interfaces. + + The `stdlib.h' header contains a definition of the following type: + + - Data Type: struct random_data + Objects of type `struct random_data' contain the information + necessary to represent the state of the PRNG. Although a complete + definition of the type is present the type should be treated as + opaque. + + The functions modifying the state follow exactly the already +described functions. + + - Function: int random_r (struct random_data *restrict BUF, int32_t + *restrict RESULT) + The `random_r' function behaves exactly like the `random' function + except that it uses and modifies the state in the object pointed + to by the first parameter instead of the global state. + + - Function: int srandom_r (unsigned int SEED, struct random_data *BUF) + The `srandom_r' function behaves exactly like the `srandom' + function except that it uses and modifies the state in the object + pointed to by the second parameter instead of the global state. + + - Function: int initstate_r (unsigned int SEED, char *restrict + STATEBUF, size_t STATELEN, struct random_data *restrict BUF) + The `initstate_r' function behaves exactly like the `initstate' + function except that it uses and modifies the state in the object + pointed to by the fourth parameter instead of the global state. + + - Function: int setstate_r (char *restrict STATEBUF, struct + random_data *restrict BUF) + The `setstate_r' function behaves exactly like the `setstate' + function except that it uses and modifies the state in the object + pointed to by the first parameter instead of the global state.  -File: libc.info, Node: Control Functions, Next: Arithmetic Functions, Prev: Rounding, Up: Arithmetic +File: libc.info, Node: SVID Random, Prev: BSD Random, Up: Pseudo-Random Numbers -Floating-Point Control Functions -================================ +SVID Random Number Function +--------------------------- - IEEE 754 floating-point implementations allow the programmer to -decide whether traps will occur for each of the exceptions, by setting -bits in the "control word". In C, traps result in the program -receiving the `SIGFPE' signal; see *Note Signal Handling::. + The C library on SVID systems contains yet another kind of random +number generator functions. They use a state of 48 bits of data. The +user can choose among a collection of functions which return the random +bits in different forms. - *Note:* IEEE 754 says that trap handlers are given details of the -exceptional situation, and can set the result value. C signals do not -provide any mechanism to pass this information back and forth. -Trapping exceptions in C is therefore not very useful. + Generally there are two kinds of function. The first uses a state of +the random number generator which is shared among several functions and +by all threads of the process. The second requires the user to handle +the state. - It is sometimes necessary to save the state of the floating-point -unit while you perform some calculation. The library provides functions -which save and restore the exception flags, the set of exceptions that -generate traps, and the rounding mode. This information is known as the -"floating-point environment". + All functions have in common that they use the same congruential +formula with the same constants. The formula is - The functions to save and restore the floating-point environment all -use a variable of type `fenv_t' to store information. This type is -defined in `fenv.h'. Its size and contents are implementation-defined. -You should not attempt to manipulate a variable of this type directly. + Y = (a * X + c) mod m - To save the state of the FPU, use one of these functions: +where X is the state of the generator at the beginning and Y the state +at the end. `a' and `c' are constants determining the way the +generator works. By default they are - - Function: int fegetenv (fenv_t *ENVP) - Store the floating-point environment in the variable pointed to by - ENVP. + a = 0x5DEECE66D = 25214903917 + c = 0xb = 11 - The function returns zero in case the operation was successful, a - non-zero value otherwise. +but they can also be changed by the user. `m' is of course 2^48 since +the state consists of a 48-bit array. - - Function: int feholdexcept (fenv_t *ENVP) - Store the current floating-point environment in the object pointed - to by ENVP. Then clear all exception flags, and set the FPU to - trap no exceptions. Not all FPUs support trapping no exceptions; - if `feholdexcept' cannot set this mode, it returns nonzero value. - If it succeeds, it returns zero. + The prototypes for these functions are in `stdlib.h'. - The functions which restore the floating-point environment can take -these kinds of arguments: + - Function: double drand48 (void) + This function returns a `double' value in the range of `0.0' to + `1.0' (exclusive). The random bits are determined by the global + state of the random number generator in the C library. - * Pointers to `fenv_t' objects, which were initialized previously by - a call to `fegetenv' or `feholdexcept'. + Since the `double' type according to IEEE 754 has a 52-bit + mantissa this means 4 bits are not initialized by the random number + generator. These are (of course) chosen to be the least + significant bits and they are initialized to `0'. - * The special macro `FE_DFL_ENV' which represents the floating-point - environment as it was available at program start. + - Function: double erand48 (unsigned short int XSUBI[3]) + This function returns a `double' value in the range of `0.0' to + `1.0' (exclusive), similarly to `drand48'. The argument is an + array describing the state of the random number generator. - * Implementation defined macros with names starting with `FE_' and - having type `fenv_t *'. + This function can be called subsequently since it updates the + array to guarantee random numbers. The array should have been + initialized before initial use to obtain reproducible results. - If possible, the GNU C Library defines a macro `FE_NOMASK_ENV' - which represents an environment where every exception raised - causes a trap to occur. You can test for this macro using - `#ifdef'. It is only defined if `_GNU_SOURCE' is defined. + - Function: long int lrand48 (void) + The `lrand48' function returns an integer value in the range of + `0' to `2^31' (exclusive). Even if the size of the `long int' + type can take more than 32 bits, no higher numbers are returned. + The random bits are determined by the global state of the random + number generator in the C library. - Some platforms might define other predefined environments. + - Function: long int nrand48 (unsigned short int XSUBI[3]) + This function is similar to the `lrand48' function in that it + returns a number in the range of `0' to `2^31' (exclusive) but the + state of the random number generator used to produce the random + bits is determined by the array provided as the parameter to the + function. -To set the floating-point environment, you can use either of these -functions: + The numbers in the array are updated afterwards so that subsequent + calls to this function yield different results (as is expected of + a random number generator).

However, if any exceptions were - flagged in the status word before `feupdateenv' was called, they - remain flagged after the call. In other words, after `feupdateenv' - is called, the status word is the bitwise OR of the previous - status word and the one saved in ENVP. + The internal state of the random number generator can be initialized +in several ways. The methods differ in the completeness of the +information provided. - The function returns zero in case the operation was successful, a - non-zero value otherwise. + - Function: void srand48 (long int SEEDVAL) + The `srand48' function sets the most significant 32 bits of the + internal state of the random number generator to the least + significant 32 bits of the SEEDVAL parameter.

Some of these functions convert -floating point numbers to integer values. They are all declared in -`math.h'. + If an application uses many floating point functions it is often the +case that the cost of the function calls themselves is not negligible. +Modern processors can often execute the operations themselves very +fast, but the function call disrupts the instruction pipeline. - You can also convert floating-point numbers to integers simply by -casting them to `int'. This discards the fractional part, effectively -rounding towards zero. However, this only works if the result can -actually be represented as an `int'--for very large numbers, this is -impossible. The functions listed here return the result as a `double' -instead to get around this problem. + For this reason the GNU C Library provides optimizations for many of +the frequently-used math functions. When GNU CC is used and the user +activates the optimizer, several new inline functions and macros are +defined. These new functions and macros have the same names as the +library functions and so are used instead of the latter. In the case of +inline functions the compiler will decide whether it is reasonable to +use them, and this decision is usually correct. - - Function: double ceil (double X) - - Function: float ceilf (float X) - - Function: long double ceill (long double X) - These functions round X upwards to the nearest integer, returning - that value as a `double'. Thus, `ceil (1.5)' is `2.0'. + This means that no calls to the library functions may be necessary, +and can increase the speed of generated code significantly. The +drawback is that code size will increase, and the increase is not +always negligible. - - Function: double floor (double X) - - Function: float floorf (float X) - - Function: long double floorl (long double X) - These functions round X downwards to the nearest integer, - returning that value as a `double'. Thus, `floor (1.5)' is `1.0' - and `floor (-1.5)' is `-2.0'. + There are two kind of inline functions: Those that give the same +result as the library functions and others that might not set `errno' +and might have a reduced precision and/or argument range in comparison +with the library functions. The latter inline functions are only +available if the flag `-ffast-math' is given to GNU CC. - - Function: double trunc (double X) - - Function: float truncf (float X) - - Function: long double truncl (long double X) - The `trunc' functions round X towards zero to the nearest integer - (returned in floating-point format). Thus, `trunc (1.5)' is `1.0' - and `trunc (-1.5)' is `-1.0'. + In cases where the inline functions and macros are not wanted the +symbol `__NO_MATH_INLINES' should be defined before any system header is +included. This will ensure that only library functions are used. Of +course, it can be determined for each file in the project whether +giving this option is preferable or not. - - Function: double rint (double X) - - Function: float rintf (float X) - - Function: long double rintl (long double X) - These functions round X to an integer value according to the - current rounding mode. *Note Floating Point Parameters::, for - information about the various rounding modes.

By default the +exception is simply noted in the floating-point "status word", and the +program continues as if nothing had happened. The operation produces a +default value, which depends on the exception (see the table below). +Your program can check the status word to find out which exceptions +happened. - This function attempts to decompose STRING as follows: + Alternatively, you can enable "traps" for exceptions. In that case, +when an exception is raised, your program will receive the `SIGFPE' +signal. The default action for this signal is to terminate the +program. *Note Signal Handling::, for how you can change the effect of +the signal. - * A (possibly empty) sequence of whitespace characters.

We support it +for historical compatibility, but recommend that you do not use it in +new programs. - * An optional plus or minus sign (`+' or `-'). +The exceptions defined in IEEE 754 are: - * A nonempty sequence of digits in the radix specified by BASE. +`Invalid Operation' + This exception is raised if the given operands are invalid for the + operation to be performed. Examples are (see IEEE 754, section 7): + 1. Addition or subtraction: oo - oo. (But oo + oo = oo). - If BASE is zero, decimal radix is assumed unless the series of - digits begins with `0' (specifying octal radix), or `0x' or - `0X' (specifying hexadecimal radix); in other words, the same - syntax used for integer constants in C. + 2. Multiplication: 0 * oo. - Otherwise BASE must have a value between `2' and `36'. If - BASE is `16', the digits may optionally be preceded by `0x' - or `0X'. If base has no legal value the value returned is - `0l' and the global variable `errno' is set to `EINVAL'. + 3. Division: 0/0 or oo/oo. - * Any remaining characters in the string. If TAILPTR is not a - null pointer, `strtol' stores a pointer to this tail in - `*TAILPTR'. + 4. Remainder: x REM y, where y is zero or x is infinite. - If the string is empty, contains only whitespace, or does not - contain an initial substring that has the expected syntax for an - integer in the specified BASE, no conversion is performed. In - this case, `strtol' returns a value of zero and the value stored in - `*TAILPTR' is the value of STRING. + 5. Square root if the operand is less then zero. More + generally, any mathematical function evaluated outside its + domain produces this exception. - In a locale other than the standard `"C"' locale, this function - may recognize additional implementation-dependent syntax. + 6. Conversion of a floating-point number to an integer or decimal + string, when the number cannot be represented in the target + format (due to overflow, infinity, or NaN). - If the string has valid syntax for an integer but the value is not - representable because of overflow, `strtol' returns either - `LONG_MAX' or `LONG_MIN' (*note Range of Type::), as appropriate - for the sign of the value. It also sets `errno' to `ERANGE' to - indicate there was overflow. + 7. Conversion of an unrecognizable input string. - You should not check for errors by examining the return value of - `strtol', because the string might be a valid representation of - `0l', `LONG_MAX', or `LONG_MIN'. Instead, check whether TAILPTR - points to what you expect after the number (e.g. `'\0'' if the - string should end after the number). You also need to clear ERRNO - before the call and check it afterward, in case there was overflow. + 8. Comparison via predicates involving < or >, when one or other + of the operands is NaN. You can prevent this exception by + using the unordered comparison functions instead; see *Note + FP Comparison Functions::. - There is an example at the end of this section. + If the exception does not trap, the result of the operation is NaN. - - Function: long int wcstol (const wchar_t *restrict STRING, wchar_t - **restrict TAILPTR, int BASE) - The `wcstol' function is equivalent to the `strtol' function in - nearly all aspects but handles wide character strings. +`Division by Zero' + This exception is raised when a finite nonzero number is divided + by zero.

The - syntax is the same as described above for `strtol'. The value - returned on overflow is `ULONG_MAX' (*note Range of Type::). + 2. Round toward 0 carries all overflows to the largest + representable finite number with the sign of the intermediate + result. - If STRING depicts a negative number, `strtoul' acts the same as - STRTOL but casts the result to an unsigned integer. That means - for example that `strtoul' on `"-1"' returns `ULONG_MAX' and an - input more negative than `LONG_MIN' returns (`ULONG_MAX' + 1) / 2. + 3. Round toward -oo carries positive overflows to the largest + representable finite number and negative overflows to -oo. - `strtoul' sets ERRNO to `EINVAL' if BASE is out of range, or - `ERANGE' on overflow. + 4.

If no trap handler is installed + the operation continues with an imprecise small value, or zero if + the destination precision cannot hold the small exact result. - If the string has valid syntax for an integer but the value is not - representable because of overflow, `strtoll' returns either - `LONG_LONG_MAX' or `LONG_LONG_MIN' (*note Range of Type::), as - appropriate for the sign of the value. It also sets `errno' to - `ERANGE' to indicate there was overflow. +`Inexact' + This exception is signalled if a rounded result is not exact (such + as when calculating the square root of two) or a result overflows + without an overflow trap. - The `strtoll' function was introduced in ISO C99. + +File: libc.info, Node: Infinity and NaN, Next: Status bit operations, Prev: FP Exceptions, Up: Floating Point Errors - - Function: long long int wcstoll (const wchar_t *restrict STRING, - wchar_t **restrict TAILPTR, int BASE) - The `wcstoll' function is equivalent to the `strtoll' function in - nearly all aspects but handles wide character strings. +Infinity and NaN +---------------- - The `wcstoll' function was introduced in Amendment 1 of ISO C90. + IEEE 754 floating point numbers can represent positive or negative +infinity, and "NaN" (not a number).

Some examples of calculations +that produce infinity or NaN: - - Function: long long int strtoq (const char *restrict STRING, char - **restrict TAILPTR, int BASE) - `strtoq' ("string-to-quad-word") is the BSD name for `strtoll'. + 1/0 = oo + log (0) = -oo + sqrt (-1) = NaN - - Function: long long int wcstoq (const wchar_t *restrict STRING, - wchar_t **restrict TAILPTR, int BASE) - The `wcstoq' function is equivalent to the `strtoq' function in - nearly all aspects but handles wide character strings. + When a calculation produces any of these values, an exception also +occurs; see *Note FP Exceptions::. - The `wcstoq' function is a GNU extension. + The basic operations and math functions all accept infinity and NaN +and produce sensible output. Infinities propagate through calculations +as one would expect: for example, 2 + oo = oo, 4/oo = 0, atan (oo) = +pi/2. NaN, on the other hand, infects any calculation that involves +it. Unless the calculation would produce the same result no matter +what real value replaced NaN, the result is NaN. - - Function: unsigned long long int strtoull (const char *restrict - STRING, char **restrict TAILPTR, int BASE) - The `strtoull' function is related to `strtoll' the same way - `strtoul' is related to `strtol'. + In comparison operations, positive infinity is larger than all values +except itself and NaN, and negative infinity is smaller than all values +except itself and NaN. NaN is "unordered": it is not equal to, greater +than, or less than anything, _including itself_. `x == x' is false if +the value of `x' is NaN. You can use this to test whether a value is +NaN or not, but the recommended way to test for NaN is with the `isnan' +function (*note Floating Point Classes::). In addition, `<', `>', +`<=', and `>=' will raise an exception when applied to NaNs. - The `strtoull' function was introduced in ISO C99. + `math.h' defines macros that allow you to explicitly set a variable +to infinity or NaN. - - Function: unsigned long long int wcstoull (const wchar_t *restrict - STRING, wchar_t **restrict TAILPTR, int BASE) - The `wcstoull' function is equivalent to the `strtoull' function - in nearly all aspects but handles wide character strings. + - Macro: float INFINITY + An expression representing positive infinity. It is equal to the + value produced by mathematical operations like `1.0 / 0.0'. + `-INFINITY' represents negative infinity. - The `wcstoull' function was introduced in Amendment 1 of ISO C90. + You can test whether a floating-point value is infinite by + comparing it to this macro. However, this is not recommended; you + should use the `isfinite' macro instead. *Note Floating Point + Classes::. - - Function: unsigned long long int strtouq (const char *restrict - STRING, char **restrict TAILPTR, int BASE) - `strtouq' is the BSD name for `strtoull'. + This macro was introduced in the ISO C99 standard. - - Function: unsigned long long int wcstouq (const wchar_t *restrict - STRING, wchar_t **restrict TAILPTR, int BASE) - The `wcstouq' function is equivalent to the `strtouq' function in - nearly all aspects but handles wide character strings. + - Macro: float NAN + An expression representing a value which is "not a number".

This +value is produced when you divide a positive number by negative +infinity, or when a negative result is smaller than the limits of +representation. Negative zero behaves identically to zero in all +calculations, unless you explicitly test the sign bit with `signbit' or +`copysign'. - If the string has valid syntax for an integer but the value is not - representable because of overflow, `strtoimax' returns either - `INTMAX_MAX' or `INTMAX_MIN' (*note Integers::), as appropriate - for the sign of the value.

It should be used unless there is a + specific need for one of the others. In this mode results are + rounded to the nearest representable value. If the result is + midway between two representable values, the even representable is + chosen. "Even" here means the lowest-order bit is zero.

If TAILPTR is not a - null pointer, a pointer to this tail of the string is stored - in `*TAILPTR'. +Round toward minus Infinity. + All results are rounded to the largest representable value which + is less than the result. - If the string is empty, contains only whitespace, or does not - contain an initial substring that has the expected syntax for a - floating-point number, no conversion is performed. In this case, - `strtod' returns a value of zero and the value returned in - `*TAILPTR' is the value of STRING. +Round toward zero. + All results are rounded to the largest representable value whose + magnitude is less than that of the result. In other words, if the + result is negative it is rounded up; if it is positive, it is + rounded down. - In a locale other than the standard `"C"' or `"POSIX"' locales, - this function may recognize additional locale-dependent syntax. +`fenv.h' defines constants which you can use to refer to the various +rounding modes.

Therefore, unless these functions do precisely what you -need, it is better to use `sprintf', which is standard. + IEEE 754 floating-point implementations allow the programmer to +decide whether traps will occur for each of the exceptions, by setting +bits in the "control word". In C, traps result in the program +receiving the `SIGFPE' signal; see *Note Signal Handling::. - All these functions are defined in `stdlib.h'. + *Note:* IEEE 754 says that trap handlers are given details of the +exceptional situation, and can set the result value. C signals do not +provide any mechanism to pass this information back and forth. +Trapping exceptions in C is therefore not very useful. - - Function: char * ecvt (double VALUE, int NDIGIT, int *DECPT, int - *NEG) - The function `ecvt' converts the floating-point number VALUE to a - string with at most NDIGIT decimal digits. The returned string - contains no decimal point or sign. The first digit of the string - is non-zero (unless VALUE is actually zero) and the last digit is - rounded to nearest. `*DECPT' is set to the index in the string of - the first digit after the decimal point. `*NEG' is set to a - nonzero value if VALUE is negative, zero otherwise. + It is sometimes necessary to save the state of the floating-point +unit while you perform some calculation. The library provides functions +which save and restore the exception flags, the set of exceptions that +generate traps, and the rounding mode. This information is known as the +"floating-point environment". - If NDIGIT decimal digits would exceed the precision of a `double' - it is reduced to a system-specific value. + The functions to save and restore the floating-point environment all +use a variable of type `fenv_t' to store information. This type is +defined in `fenv.h'. Its size and contents are implementation-defined. +You should not attempt to manipulate a variable of this type directly. - The returned string is statically allocated and overwritten by - each call to `ecvt'. + To save the state of the FPU, use one of these functions: - If VALUE is zero, it is implementation defined whether `*DECPT' is - `0' or `1'. + - Function: int fegetenv (fenv_t *ENVP) + Store the floating-point environment in the variable pointed to by + ENVP. - For example: `ecvt (12.3, 5, &d, &n)' returns `"12300"' and sets D - to `2' and N to `0'. + The function returns zero in case the operation was successful, a + non-zero value otherwise. - - Function: char * fcvt (double VALUE, int NDIGIT, int *DECPT, int - *NEG) - The function `fcvt' is like `ecvt', but NDIGIT specifies the - number of digits after the decimal point. If NDIGIT is less than - zero, VALUE is rounded to the NDIGIT+1'th place to the left of the - decimal point. For example, if NDIGIT is `-1', VALUE will be - rounded to the nearest 10. If NDIGIT is negative and larger than - the number of digits to the left of the decimal point in VALUE, - VALUE will be rounded to one significant digit. + - Function: int feholdexcept (fenv_t *ENVP) + Store the current floating-point environment in the object pointed + to by ENVP. Then clear all exception flags, and set the FPU to + trap no exceptions. Not all FPUs support trapping no exceptions; + if `feholdexcept' cannot set this mode, it returns nonzero value. + If it succeeds, it returns zero. - If NDIGIT decimal digits would exceed the precision of a `double' - it is reduced to a system-specific value. + The functions which restore the floating-point environment can take +these kinds of arguments: - The returned string is statically allocated and overwritten by - each call to `fcvt'. + * Pointers to `fenv_t' objects, which were initialized previously by + a call to `fegetenv' or `feholdexcept'. - - Function: char * gcvt (double VALUE, int NDIGIT, char *BUF) - `gcvt' is functionally equivalent to `sprintf(buf, "%*g", ndigit, - value'.

It returns - BUF. + * The special macro `FE_DFL_ENV' which represents the floating-point + environment as it was available at program start. - If NDIGIT decimal digits would exceed the precision of a `double' - it is reduced to a system-specific value. + * Implementation defined macros with names starting with `FE_' and + having type `fenv_t *'. - As extensions, the GNU C library provides versions of these three -functions that take `long double' arguments. + If possible, the GNU C Library defines a macro `FE_NOMASK_ENV' + which represents an environment where every exception raised + causes a trap to occur. You can test for this macro using + `#ifdef'. It is only defined if `_GNU_SOURCE' is defined. - - Function: char * qecvt (long double VALUE, int NDIGIT, int *DECPT, - int *NEG) - This function is equivalent to `ecvt' except that it takes a `long - double' for the first parameter and that NDIGIT is restricted by - the precision of a `long double'. + Some platforms might define other predefined environments. - - Function: char * qfcvt (long double VALUE, int NDIGIT, int *DECPT, - int *NEG) - This function is equivalent to `fcvt' except that it takes a `long - double' for the first parameter and that NDIGIT is restricted by - the precision of a `long double'. +To set the floating-point environment, you can use either of these +functions: - - Function: char * qgcvt (long double VALUE, int NDIGIT, char *BUF) - This function is equivalent to `gcvt' except that it takes a `long - double' for the first parameter and that NDIGIT is restricted by - the precision of a `long double'. + - Function: int fesetenv (const fenv_t *ENVP) + Set the floating-point environment to that described by ENVP. - The `ecvt' and `fcvt' functions, and their `long double' -equivalents, all return a string located in a static buffer which is -overwritten by the next call to the function.

These have the conventional `_r' -suffix. + The function returns zero in case the operation was successful, a + non-zero value otherwise. - `gcvt_r' is not necessary, because `gcvt' already uses a -user-supplied buffer. + - Function: int feupdateenv (const fenv_t *ENVP) + Like `fesetenv', this function sets the floating-point environment + to that described by ENVP.

In this -manual, we use a rigorous terminology to avoid confusion, and the only -thing we use the simple word "time" for is to talk about the abstract -concept. + These functions are provided for obtaining the "absolute value" (or +"magnitude") of a number. The absolute value of a real number X is X +if X is positive, -X if X is negative. For a complex number Z, whose +real part is X and whose imaginary part is Y, the absolute value is +`sqrt (X*X + Y*Y)'. - A "calendar time" is a point in the time continuum, for example -November 4, 1990 at 18:02.5 UTC. Sometimes this is called "absolute -time". + Prototypes for `abs', `labs' and `llabs' are in `stdlib.h'; +`imaxabs' is declared in `inttypes.h'; `fabs', `fabsf' and `fabsl' are +declared in `math.h'. `cabs', `cabsf' and `cabsl' are declared in +`complex.h'. - We don't speak of a "date", because that is inherent in a calendar -time. + - Function: int abs (int NUMBER) + - Function: long int labs (long int NUMBER) + - Function: long long int llabs (long long int NUMBER) + - Function: intmax_t imaxabs (intmax_t NUMBER) + These functions return the absolute value of NUMBER. - An "interval" is a contiguous part of the time continuum between two -calendar times, for example the hour between 9:00 and 10:00 on July 4, -1980. + Most computers use a two's complement integer representation, in + which the absolute value of `INT_MIN' (the smallest possible `int') + cannot be represented; thus, `abs (INT_MIN)' is not defined. - An "elapsed time" is the length of an interval, for example, 35 -minutes. People sometimes sloppily use the word "interval" to refer to -the elapsed time of some interval. + `llabs' and `imaxdiv' are new to ISO C99. - An "amount of time" is a sum of elapsed times, which need not be of -any specific intervals. For example, the amount of time it takes to -read a book might be 9 hours, independently of when and in how many -sittings it is read. + See *Note Integers:: for a description of the `intmax_t' type. - A "period" is the elapsed time of an interval between two events, -especially when they are part of a sequence of regularly repeating -events. - "CPU time" is like calendar time, except that it is based on the -subset of the time continuum when a particular process is actively -using a CPU. CPU time is, therefore, relative to a process. + - Function: double fabs (double NUMBER) + - Function: float fabsf (float NUMBER) + - Function: long double fabsl (long double NUMBER) + This function returns the absolute value of the floating-point + number NUMBER. - "Processor time" is an amount of time that a CPU is in use. In -fact, it's a basic system resource, since there's a limit to how much -can exist in any given interval (that limit is the elapsed time of the -interval times the number of CPUs in the processor). People often call -this CPU time, but we reserve the latter term in this manual for the -definition above. + - Function: double cabs (complex double Z) + - Function: float cabsf (complex float Z) + - Function: long double cabsl (complex long double Z) + These functions return the absolute value of the complex number Z + (*note Complex Numbers::).

It may + also take advantage of hardware support for this operation. See + `hypot' in *Note Exponents and Logarithms::. - One way to represent an elapsed time is with a simple arithmetic data -type, as with the following function to compute the elapsed time between -two calendar times. This function is declared in `time.h'. + +File: libc.info, Node: Normalization Functions, Next: Rounding Functions, Prev: Absolute Value, Up: Arithmetic Functions - - Function: double difftime (time_t TIME1, time_t TIME0) - The `difftime' function returns the number of seconds of elapsed - time between calendar time TIME1 and calendar time TIME0, as a - value of type `double'. The difference ignores leap seconds - unless leap second support is enabled. +Normalization Functions +----------------------- - In the GNU system, you can simply subtract `time_t' values. But on - other systems, the `time_t' data type might use some other encoding - where subtraction doesn't work directly. + The functions described in this section are primarily provided as a +way to efficiently perform certain low-level manipulations on floating +point numbers that are represented internally using a binary radix; see +*Note Floating Point Concepts::. These functions are required to have +equivalent behavior even if the representation does not use a radix of +2, but of course they are unlikely to be particularly efficient in +those cases. - The GNU C library provides two data types specifically for -representing an elapsed time. They are used by various GNU C library -functions, and you can use them for your own purposes too. They're -exactly the same except that one has a resolution in microseconds, and -the other, newer one, is in nanoseconds. + All these functions are declared in `math.h'. - - Data Type: struct timeval - The `struct timeval' structure represents an elapsed time. It is - declared in `sys/time.h' and has the following members: + - Function: double frexp (double VALUE, int *EXPONENT) + - Function: float frexpf (float VALUE, int *EXPONENT) + - Function: long double frexpl (long double VALUE, int *EXPONENT) + These functions are used to split the number VALUE into a + normalized fraction and an exponent. - `long int tv_sec' - This represents the number of whole seconds of elapsed time. + If the argument VALUE is not zero, the return value is VALUE times + a power of two, and is always in the range 1/2 (inclusive) to 1 + (exclusive). The corresponding exponent is stored in `*EXPONENT'; + the return value multiplied by 2 raised to this exponent equals + the original number VALUE. - `long int tv_usec' - This is the rest of the elapsed time (a fraction of a second), - represented as the number of microseconds. It is always less - than one million. + For example, `frexp (12.8, &exponent)' returns `0.8' and stores + `4' in `exponent'. + If VALUE is zero, then the return value is zero and zero is stored + in `*EXPONENT'. - - Data Type: struct timespec - The `struct timespec' structure represents an elapsed time. It is - declared in `time.h' and has the following members: + - Function: double ldexp (double VALUE, int EXPONENT) + - Function: float ldexpf (float VALUE, int EXPONENT) + - Function: long double ldexpl (long double VALUE, int EXPONENT) + These functions return the result of multiplying the floating-point + number VALUE by 2 raised to the power EXPONENT. (It can be used + to reassemble floating-point numbers that were taken apart by + `frexp'.) - `long int tv_sec' - This represents the number of whole seconds of elapsed time. + For example, `ldexp (0.8, 4)' returns `12.8'. - `long int tv_nsec' - This is the rest of the elapsed time (a fraction of a second), - represented as the number of nanoseconds. It is always less - than one billion. + The following functions, which come from BSD, provide facilities +equivalent to those of `ldexp' and `frexp'.

For that, -calendar time and elapsed times are useless because a process may spend -time waiting for I/O or for other processes to use the CPU. However, -you can get the information with the functions in this section. - - CPU time (*note Time Basics::) is represented by the data type -`clock_t', which is a number of "clock ticks". It gives the total -amount of time a process has actively used a CPU since some arbitrary -event. On the GNU system, that event is the creation of the process. -While arbitrary in general, the event is always the same event for any -particular process, so you can always measure how much time on the CPU -a particular computation takes by examinining the process' CPU time -before and after the computation. +File: libc.info, Node: Rounding Functions, Next: Remainder Functions, Prev: Normalization Functions, Up: Arithmetic Functions - In the GNU system, `clock_t' is equivalent to `long int' and -`CLOCKS_PER_SEC' is an integer value. But in other systems, both -`clock_t' and the macro `CLOCKS_PER_SEC' can be either integer or -floating-point types. Casting CPU time values to `double', as in the -example above, makes sure that operations such as arithmetic and -printing work properly and consistently no matter what the underlying -representation is. +Rounding Functions +------------------ - Note that the clock can wrap around. On a 32bit system with -`CLOCKS_PER_SEC' set to one million this function will return the same -value approximately every 72 minutes. + The functions listed here perform operations such as rounding and +truncation of floating-point values. Some of these functions convert +floating point numbers to integer values. They are all declared in +`math.h'. - For additional functions to examine a process' use of processor time, -and to control it, *Note Resource Usage And Limitation::. + You can also convert floating-point numbers to integers simply by +casting them to `int'. This discards the fractional part, effectively +rounding towards zero. However, this only works if the result can +actually be represented as an `int'--for very large numbers, this is +impossible. The functions listed here return the result as a `double' +instead to get around this problem. -* Menu: + - Function: double ceil (double X) + - Function: float ceilf (float X) + - Function: long double ceill (long double X) + These functions round X upwards to the nearest integer, returning + that value as a `double'.

This -facility is declared in the header file `time.h'. + If X was not initially an integer, these functions raise the + inexact exception. - In typical usage, you call the `clock' function at the beginning and -end of the interval you want to time, subtract the values, and then -divide by `CLOCKS_PER_SEC' (the number of clock ticks per second) to -get processor time, like this: + - Function: double nearbyint (double X) + - Function: float nearbyintf (float X) + - Function: long double nearbyintl (long double X) + These functions return the same value as the `rint' functions, but + do not raise the inexact exception if X is not an integer. - #include - - clock_t start, end; - double cpu_time_used; - - start = clock(); - ... /* Do the work. */ - end = clock(); - cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC; + - Function: double round (double X) + - Function: float roundf (float X) + - Function: long double roundl (long double X) + These functions are similar to `rint', but they round halfway + cases away from zero instead of to the nearest even integer. - Do not use a single CPU time as an amount of time; it doesn't work -that way.

Sometimes this is called "absolute +time". - This format is a POSIX.2 extension and also appears in - ISO C99. + We don't speak of a "date", because that is inherent in a calendar +time. - `%T' - The time of day using decimal numbers using the format - `%H:%M:%S'. + An "interval" is a contiguous part of the time continuum between two +calendar times, for example the hour between 9:00 and 10:00 on July 4, +1980. - This format is a POSIX.2 extension. + An "elapsed time" is the length of an interval, for example, 35 +minutes. People sometimes sloppily use the word "interval" to refer to +the elapsed time of some interval. - `%u' - The day of the week as a decimal number (range `1' through - `7'), Monday being `1'. + An "amount of time" is a sum of elapsed times, which need not be of +any specific intervals. For example, the amount of time it takes to +read a book might be 9 hours, independently of when and in how many +sittings it is read. - This format is a POSIX.2 extension and also appears in - ISO C99. + A "period" is the elapsed time of an interval between two events, +especially when they are part of a sequence of regularly repeating +events. - `%U' - The week number of the current year as a decimal number - (range `00' through `53'), starting with the first Sunday as - the first day of the first week. Days preceding the first - Sunday in the year are considered to be in week `00'. + "CPU time" is like calendar time, except that it is based on the +subset of the time continuum when a particular process is actively +using a CPU. CPU time is, therefore, relative to a process. - `%V' - The ISO 8601:1988 week number as a decimal number (range `01' - through `53'). ISO weeks start with Monday and end with - Sunday. Week `01' of a year is the first week which has the - majority of its days in that year; this is equivalent to the - week containing the year's first Thursday, and it is also - equivalent to the week containing January 4. Week `01' of a - year can contain days from the previous year. The week - before week `01' of a year is the last week (`52' or `53') of - the previous year even if it contains days from the new year. + "Processor time" is an amount of time that a CPU is in use. In +fact, it's a basic system resource, since there's a limit to how much +can exist in any given interval (that limit is the elapsed time of the +interval times the number of CPUs in the processor). People often call +this CPU time, but we reserve the latter term in this manual for the +definition above. - This format is a POSIX.2 extension and also appears in - ISO C99. + +File: libc.info, Node: Elapsed Time, Next: Processor And CPU Time, Prev: Time Basics, Up: Date and Time - `%w' - The day of the week as a decimal number (range `0' through - `6'), Sunday being `0'. +Elapsed Time +============ - `%W' - The week number of the current year as a decimal number - (range `00' through `53'), starting with the first Monday as - the first day of the first week. All days preceding the - first Monday in the year are considered to be in week `00'. + One way to represent an elapsed time is with a simple arithmetic data +type, as with the following function to compute the elapsed time between +two calendar times. This function is declared in `time.h'. - `%x' - The preferred date representation for the current locale. + - Function: double difftime (time_t TIME1, time_t TIME0) + The `difftime' function returns the number of seconds of elapsed + time between calendar time TIME1 and calendar time TIME0, as a + value of type `double'. The difference ignores leap seconds + unless leap second support is enabled. - `%X' - The preferred time of day representation for the current - locale. + In the GNU system, you can simply subtract `time_t' values. But on + other systems, the `time_t' data type might use some other encoding + where subtraction doesn't work directly. - `%y' - The year without a century as a decimal number (range `00' - through `99'). This is equivalent to the year modulo 100. + The GNU C library provides two data types specifically for +representing an elapsed time. They are used by various GNU C library +functions, and you can use them for your own purposes too. They're +exactly the same except that one has a resolution in microseconds, and +the other, newer one, is in nanoseconds. - `%Y' - The year as a decimal number, using the Gregorian calendar. - Years before the year `1' are numbered `0', `-1', and so on. + - Data Type: struct timeval + The `struct timeval' structure represents an elapsed time. It is + declared in `sys/time.h' and has the following members: - `%z' - RFC 822/ISO 8601:1988 style numeric time zone (e.g., `-0600' - or `+0100'), or nothing if no time zone is determinable. + `long int tv_sec' + This represents the number of whole seconds of elapsed time. - This format was introduced in ISO C99 but was previously - available as a GNU extension. + `long int tv_usec' + This is the rest of the elapsed time (a fraction of a second), + represented as the number of microseconds. It is always less + than one million. - A full RFC 822 timestamp is generated by the format - `"%a, %d %b %Y %H:%M:%S %z"' (or the equivalent - `"%a, %d %b %Y %T %z"'). - `%Z' - The time zone abbreviation (empty if the time zone can't be - determined). + - Data Type: struct timespec + The `struct timespec' structure represents an elapsed time. It is + declared in `time.h' and has the following members: - `%%' - A literal `%' character. + `long int tv_sec' + This represents the number of whole seconds of elapsed time. - The SIZE parameter can be used to specify the maximum number of - characters to be stored in the array S, including the terminating - null character. If the formatted time requires more than SIZE - characters, `strftime' returns zero and the contents of the array - S are undefined. Otherwise the return value indicates the number - of characters placed in the array S, not including the terminating - null character. + `long int tv_nsec' + This is the rest of the elapsed time (a fraction of a second), + represented as the number of nanoseconds. It is always less + than one billion. - _Warning:_ This convention for the return value which is prescribed - in ISO C can lead to problems in some situations. For certain - format strings and certain locales the output really can be the - empty string and this cannot be discovered by testing the return - value only. E.g., in most locales the AM/PM time format is not - supported (most of the world uses the 24 hour time - representation). In such locales `"%p"' will return the empty - string, i.e., the return value is zero. To detect situations like - this something similar to the following code should be used: - buf[0] = '\1'; - len = strftime (buf, bufsize, format, tp); - if (len == 0 && buf[0] != '\0') - { - /* Something went wrong in the strftime call. */ - ... - } + It is often necessary to subtract two values of type +`struct timeval' or `struct timespec'. Here is the best way to do +this. It works even on some peculiar operating systems where the +`tv_sec' member has an unsigned type. - If S is a null pointer, `strftime' does not actually write - anything, but instead returns the number of characters it would - have written. + /* Subtract the `struct timeval' values X and Y, + storing the result in RESULT. + Return 1 if the difference is negative, otherwise 0. */ + + int + timeval_subtract (result, x, y) + struct timeval *result, *x, *y; + { + /* Perform the carry for the later subtraction by updating Y. */ + if (x->tv_usec < y->tv_usec) { + int nsec = (y->tv_usec - x->tv_usec) / 1000000 + 1; + y->tv_usec -= 1000000 * nsec; + y->tv_sec += nsec; + } + if (x->tv_usec - y->tv_usec > 1000000) { + int nsec = (x->tv_usec - y->tv_usec) / 1000000; + y->tv_usec += 1000000 * nsec; + y->tv_sec -= nsec; + } + + /* Compute the time remaining to wait. + `tv_usec' is certainly positive. */ + result->tv_sec = x->tv_sec - y->tv_sec; + result->tv_usec = x->tv_usec - y->tv_usec; + + /* Return 1 if result is negative. */ + return x->tv_sec < y->tv_sec; + } - According to POSIX.1 every call to `strftime' implies a call to - `tzset'. So the contents of the environment variable `TZ' is - examined before any output is produced. + Common functions that use `struct timeval' are `gettimeofday' and +`settimeofday'. - For an example of `strftime', see *Note Time Functions Example::. + There are no GNU C library functions specifically oriented toward +dealing with elapsed times, but the calendar time, processor time, and +alarm and sleeping functions have a lot to do with them. - - Function: size_t wcsftime (wchar_t *S, size_t SIZE, const wchar_t - *TEMPLATE, const struct tm *BROKENTIME) - The `wcsftime' function is equivalent to the `strftime' function - with the difference that it operates on wide character strings. - The buffer where the result is stored, pointed to by S, must be an - array of wide characters. The parameter SIZE which specifies the - size of the output buffer gives the number of wide character, not - the number of bytes. + +File: libc.info, Node: Processor And CPU Time, Next: Calendar Time, Prev: Elapsed Time, Up: Date and Time - Also the format string TEMPLATE is a wide character string. Since - all characters needed to specify the format string are in the basic - character set it is portably possible to write format strings in - the C source code using the `L"..."' notation. The parameter - BROKENTIME has the same meaning as in the `strftime' call. +Processor And CPU Time +====================== - The `wcsftime' function supports the same flags, modifiers, and - format specifiers as the `strftime' function. + If you're trying to optimize your program or measure its efficiency, +it's very useful to know how much processor time it uses. For that, +calendar time and elapsed times are useless because a process may spend +time waiting for I/O or for other processes to use the CPU. However, +you can get the information with the functions in this section. - The return value of `wcsftime' is the number of wide characters - stored in `s'. When more characters would have to be written than - can be placed in the buffer S the return value is zero, with the - same problems indicated in the `strftime' documentation. + CPU time (*note Time Basics::) is represented by the data type +`clock_t', which is a number of "clock ticks". It gives the total +amount of time a process has actively used a CPU since some arbitrary +event. On the GNU system, that event is the creation of the process. +While arbitrary in general, the event is always the same event for any +particular process, so you can always measure how much time on the CPU +a particular computation takes by examinining the process' CPU time +before and after the computation. - -File: libc.info, Node: Parsing Date and Time, Next: TZ Variable, Prev: Formatting Calendar Time, Up: Calendar Time + In the GNU system, `clock_t' is equivalent to `long int' and +`CLOCKS_PER_SEC' is an integer value. But in other systems, both +`clock_t' and the macro `CLOCKS_PER_SEC' can be either integer or +floating-point types. Casting CPU time values to `double', as in the +example above, makes sure that operations such as arithmetic and +printing work properly and consistently no matter what the underlying +representation is. -Convert textual time and date information back ----------------------------------------------- + Note that the clock can wrap around. On a 32bit system with +`CLOCKS_PER_SEC' set to one million this function will return the same +value approximately every 72 minutes. - The ISO C standard does not specify any functions which can convert -the output of the `strftime' function back into a binary format. This -led to a variety of more-or-less successful implementations with -different interfaces over the years. Then the Unix standard was -extended by the addition of two functions: `strptime' and `getdate'. -Both have strange interfaces but at least they are widely available. + For additional functions to examine a process' use of processor time, +and to control it, *Note Resource Usage And Limitation::. * Menu: -* Low-Level Time String Parsing:: Interpret string according to given format. -* General Time String Parsing:: User-friendly function to parse data and - time strings. +* CPU Time:: The `clock' function. +* Processor Time:: The `times' function.  -File: libc.info, Node: Low-Level Time String Parsing, Next: General Time String Parsing, Up: Parsing Date and Time - -Interpret string according to given format -.......................................... - - he first function is rather low-level.

The only difference is that - the flags `_', `-', `0', and `^' are not allowed.

Use `adjtime' (below) + to make a smooth transition from one time to another by temporarily + speeding up or slowing down the clock. - `%EX' - Like `%X' but the locale's alternative time representation is - used. + With a Linux kernel, `adjtimex' does the same thing and can also + make permanent changes to the speed of the system clock so it + doesn't need to be corrected as often. - `%y' - The year without a century as a decimal number (range `0' - through `99'). + The return value is `0' on success and `-1' on failure. The + following `errno' error conditions are defined for this function: - Leading zeroes are permitted but not required. + `EPERM' + This process cannot set the clock because it is not + privileged. - Note that it is questionable to use this format without the - `%C' format. The `strptime' function does regard input - values in the range 68 to 99 as the years 1969 to 1999 and - the values 0 to 68 as the years 2000 to 2068. But maybe this - heuristic fails for some input data. + `ENOSYS' + The operating system does not support setting time zone + information, and TZP is not a null pointer. - Therefore it is best to avoid `%y' completely and use `%Y' - instead. + - Function: int adjtime (const struct timeval *DELTA, struct timeval + *OLDDELTA) + This function speeds up or slows down the system clock in order to + make a gradual adjustment. This ensures that the calendar time + reported by the system clock is always monotonically increasing, + which might not happen if you simply set the clock. - `%Ey' - The offset from `%EC' in the locale's alternative - representation. + The DELTA argument specifies a relative adjustment to be made to + the clock time. If negative, the system clock is slowed down for a + while until it has lost this much elapsed time. If positive, the + system clock is speeded up for a while. - `%Oy' - The offset of the year (from `%C') using the locale's - alternative numeric symbols. + If the OLDDELTA argument is not a null pointer, the `adjtime' + function returns information about any previous time adjustment + that has not yet completed. - `%Y' - The year as a decimal number, using the Gregorian calendar. + This function is typically used to synchronize the clocks of + computers in a local network. You must be a privileged user to + use it. - `%EY' - The full alternative year representation. + With a Linux kernel, you can use the `adjtimex' function to + permanently change the clock speed. - `%z' - Equivalent to the use of `%a, %d %b %Y %H:%M:%S %z' in this - place. This is the full ISO 8601 date and time format. + The return value is `0' on success and `-1' on failure. The + following `errno' error condition is defined for this function: - `%Z' - The timezone name. + `EPERM' + You do not have privilege to set the time. - _Note:_ Currently, this is not fully implemented. The format - is recognized, input is consumed but no field in TM is set. + *Portability Note:* The `gettimeofday', `settimeofday', and +`adjtime' functions are derived from BSD. - `%%' - A literal `%' character. + Symbols for the following function are declared in `sys/timex.h'. - All other characters in the format string must have a matching - character in the input string. Exceptions are white spaces in the - input string which can match zero or more white space characters - in the format string. + - Function: int adjtimex (struct timex *TIMEX) + `adjtimex' is functionally identical to `ntp_adjtime'. *Note High + Accuracy Clock::. - The `strptime' function processes the input string from right to - left. Each of the three possible input elements (white space, - literal, or format) are handled one after the other. If the input - cannot be matched to the format string the function stops. The - remainder of the format and input strings are not processed. + This function is present only with a Linux kernel. - The function returns a pointer to the first character it was - unable to process. If the input string contains more characters - than required by the format string the return value points right - after the last consumed input character. If the whole input - string is consumed the return value points to the `NULL' byte at - the end of the string. If an error occurs, i.e. `strptime' fails - to match all of the format string, the function returns `NULL'. - The specification of the function in the XPG standard is rather -vague, leaving out a few important pieces of information. Most -importantly, it does not specify what happens to those elements of TM -which are not directly initialized by the different formats. The -implementations on different Unix systems vary here. + +File: libc.info, Node: Broken-down Time, Next: High Accuracy Clock, Prev: High-Resolution Calendar, Up: Calendar Time - The GNU libc implementation does not touch those fields which are not -directly initialized. Exceptions are the `tm_wday' and `tm_yday' -elements, which are recomputed if any of the year, month, or date -elements changed. This has two implications: +Broken-down Time +---------------- - * Before calling the `strptime' function for a new input string, you - should prepare the TM structure you pass. Normally this will mean - initializing all values are to zero. Alternatively, you can set - all fields to values like `INT_MAX', allowing you to determine - which elements were set by the function call. Zero does not work - here since it is a valid value for many of the fields. + Calendar time is represented by the usual GNU C library functions as +an elapsed time since a fixed base calendar time. This is convenient +for computation, but has no relation to the way people normally think of +calendar time. By contrast, "broken-down time" is a binary +representation of calendar time separated into year, month, day, and so +on. Broken-down time values are not useful for calculations, but they +are useful for printing human readable time information. - Careful initialization is necessary if you want to find out - whether a certain field in TM was initialized by the function call. + A broken-down time value is always relative to a choice of time +zone, and it also indicates which time zone that is. - * You can construct a `struct tm' value with several consecutive - `strptime' calls. A useful application of this is e.g. the parsing - of two separate strings, one containing date information and the - other time information. By parsing one after the other without - clearing the structure in-between, you can construct a complete - broken-down time. + The symbols in this section are declared in the header file `time.h'. - The following example shows a function which parses a string which is -contains the date information in either US style or ISO 8601 form: + - Data Type: struct tm + This is the data type used to represent a broken-down time. The + structure contains at least the following members, which can + appear in any order. - const char * - parse_date (const char *input, struct tm *tm) - { - const char *cp; - - /* First clear the result structure. */ - memset (tm, '\0', sizeof (*tm)); - - /* Try the ISO format first. */ - cp = strptime (input, "%F", tm); - if (cp == NULL) - { - /* Does not match. Try the US form. */ - cp = strptime (input, "%D", tm); - } - - return cp; - } + `int tm_sec' + This is the number of full seconds since the top of the + minute (normally in the range `0' through `59', but the + actual upper limit is `60', to allow for leap seconds if leap + second support is available). - -File: libc.info, Node: General Time String Parsing, Prev: Low-Level Time String Parsing, Up: Parsing Date and Time + `int tm_min' + This is the number of full minutes since the top of the hour + (in the range `0' through `59'). -A More User-friendly Way to Parse Times and Dates -................................................. + `int tm_hour' + This is the number of full hours past midnight (in the range + `0' through `23'). - The Unix standard defines another function for parsing date strings. -The interface is weird, but if the function happens to suit your -application it is just fine. It is problematic to use this function in -multi-threaded programs or libraries, since it returns a pointer to a -static variable, and uses a global variable and global state (an -environment variable). + `int tm_mday' + This is the ordinal day of the month (in the range `1' + through `31'). Watch out for this one! As the only ordinal + number in the structure, it is inconsistent with the rest of + the structure. - - Variable: getdate_err - This variable of type `int' contains the error code of the last - unsuccessful call to `getdate'. Defined values are: + `int tm_mon' + This is the number of full calendar months since the + beginning of the year (in the range `0' through `11'). Watch + out for this one! People usually use ordinal numbers for + month-of-year (where January = 1). - 1 - The environment variable `DATEMSK' is not defined or null. + `int tm_year' + This is the number of full calendar years since 1900. - 2 - The template file denoted by the `DATEMSK' environment - variable cannot be opened. + `int tm_wday' + This is the number of full days since Sunday (in the range + `0' through `6'). - 3 - Information about the template file cannot retrieved. + `int tm_yday' + This is the number of full days since the beginning of the + year (in the range `0' through `365'). - 4 - The template file is not a regular file. + `int tm_isdst' + This is a flag that indicates whether Daylight Saving Time is + (or was, or will be) in effect at the time described. The + value is positive if Daylight Saving Time is in effect, zero + if it is not, and negative if the information is not + available. - 5 - An I/O error occurred while reading the template file. + `long int tm_gmtoff' + This field describes the time zone that was used to compute + this broken-down time value, including any adjustment for + daylight saving; it is the number of seconds that you must + add to UTC to get local time. You can also think of this as + the number of seconds east of UTC. For example, for U.S. + Eastern Standard Time, the value is `-5*60*60'. The + `tm_gmtoff' field is derived from BSD and is a GNU library + extension; it is not visible in a strict ISO C environment. - 6 - Not enough memory available to execute the function. + `const char *tm_zone' + This field is the name for the time zone that was used to + compute this broken-down time value. Like `tm_gmtoff', this + field is a BSD and GNU extension, and is not visible in a + strict ISO C environment. - 7 - The template file contains no matching template. + - Function: struct tm * localtime (const time_t *TIME) + The `localtime' function converts the simple time pointed to by + TIME to broken-down time representation, expressed relative to the + user's specified time zone. - 8 - The input date is invalid, but would match a template - otherwise. This includes dates like February 31st, and dates - which cannot be represented in a `time_t' variable. + The return value is a pointer to a static broken-down time + structure, which might be overwritten by subsequent calls to + `ctime', `gmtime', or `localtime'. (But no other library function + overwrites the contents of this object.) - - Function: struct tm * getdate (const char *STRING) - The interface to `getdate' is the simplest possible for a function - to parse a string and return the value. STRING is the input - string and the result is returned in a statically-allocated - variable. + The return value is the null pointer if TIME cannot be represented + as a broken-down time; typically this is because the year cannot + fit into an `int'. - The details about how the string is processed are hidden from the - user. In fact, they can be outside the control of the program. - Which formats are recognized is controlled by the file named by - the environment variable `DATEMSK'. This file should contain - lines of valid format strings which could be passed to `strptime'. + Calling `localtime' has one other effect: it sets the variable + `tzname' with information about the current time zone. *Note Time + Zone Functions::. - The `getdate' function reads these format strings one after the - other and tries to match the input string. The first line which - completely matches the input string is used. + Using the `localtime' function is a big problem in multi-threaded +programs. The result is returned in a static buffer and this is used in +all threads. POSIX.1c introduced a variant of this function. - Elements not initialized through the format string retain the - values present at the time of the `getdate' function call. + - Function: struct tm * localtime_r (const time_t *TIME, struct tm + *RESULTP) + The `localtime_r' function works just like the `localtime' + function. It takes a pointer to a variable containing a simple + time and converts it to the broken-down time format. - The formats recognized by `getdate' are the same as for - `strptime'. See above for an explanation. There are only a few - extensions to the `strptime' behavior: + But the result is not placed in a static buffer. Instead it is + placed in the object of type `struct tm' to which the parameter + RESULTP points. - * If the `%Z' format is given the broken-down time is based on - the current time of the timezone matched, not of the current - timezone of the runtime environment. + If the conversion is successful the function returns a pointer to + the object the result was written into, i.e., it returns RESULTP. - _Note_: This is not implemented (currently). The problem is - that timezone names are not unique. If a fixed timezone is - assumed for a given string (say `EST' meaning US East Coast - time), then uses for countries other than the USA will fail. - So far we have found no good solution to this. + - Function: struct tm * gmtime (const time_t *TIME) + This function is similar to `localtime', except that the + broken-down time is expressed as Coordinated Universal Time (UTC) + (formerly called Greenwich Mean Time (GMT)) rather than relative + to a local time zone. - * If only the weekday is specified the selected day depends on - the current date. If the current weekday is greater or equal - to the `tm_wday' value the current week's day is chosen, - otherwise the day next week is chosen. - * A similar heuristic is used when only the month is given and - not the year. If the month is greater than or equal to the - current month, then the current year is used. Otherwise it - wraps to next year. The first day of the month is assumed if - one is not explicitly specified. + As for the `localtime' function we have the problem that the result +is placed in a static variable. POSIX.1c also provides a replacement +for `gmtime'. - * The current hour, minute, and second are used if the - appropriate value is not set through the format. + - Function: struct tm * gmtime_r (const time_t *TIME, struct tm + *RESULTP) + This function is similar to `localtime_r', except that it converts + just like `gmtime' the given time as Coordinated Universal Time. - * If no date is given tomorrow's date is used if the time is - smaller than the current time. Otherwise today's date is - taken. + If the conversion is successful the function returns a pointer to + the object the result was written into, i.e., it returns RESULTP. - It should be noted that the format in the template file need not - only contain format elements. The following is a list of possible - format strings (taken from the Unix standard): + - Function: time_t mktime (struct tm *BROKENTIME) + The `mktime' function is used to convert a broken-down time + structure to a simple time representation. It also "normalizes" + the contents of the broken-down time structure, by filling in the + day of week and day of year based on the other date and time + components. - %m - %A %B %d, %Y %H:%M:%S - %A - %B - %m/%d/%y %I %p - %d,%m,%Y %H:%M - at %A the %dst of %B in %Y - run job at %I %p,%B %dnd - %A den %d. %B %Y %H.%M Uhr + The `mktime' function ignores the specified contents of the + `tm_wday' and `tm_yday' members of the broken-down time structure. + It uses the values of the other components to determine the + calendar time; it's permissible for these components to have + unnormalized values outside their normal ranges. The last thing + that `mktime' does is adjust the components of the BROKENTIME + structure (including the `tm_wday' and `tm_yday'). - As you can see, the template list can contain very specific - strings like `run job at %I %p,%B %dnd'. Using the above list of - templates and assuming the current time is Mon Sep 22 12:19:47 EDT - 1986 we can obtain the following results for the given input. + If the specified broken-down time cannot be represented as a + simple time, `mktime' returns a value of `(time_t)(-1)' and does + not modify the contents of BROKENTIME. - Input Match Result - Mon %a Mon Sep 22 12:19:47 EDT 1986 - Sun %a Sun Sep 28 12:19:47 EDT 1986 - Fri %a Fri Sep 26 12:19:47 EDT 1986 - September %B Mon Sep 1 12:19:47 EDT 1986 - January %B Thu Jan 1 12:19:47 EST 1987 - December %B Mon Dec 1 12:19:47 EST 1986 - Sep Mon %b %a Mon Sep 1 12:19:47 EDT 1986 - Jan Fri %b %a Fri Jan 2 12:19:47 EST 1987 - Dec Mon %b %a Mon Dec 1 12:19:47 EST 1986 - Jan Wed 1989 %b %a %Y Wed Jan 4 12:19:47 EST 1989 - Fri 9 %a %H Fri Sep 26 09:00:00 EDT 1986 - Feb 10:30 %b %H:%S Sun Feb 1 10:00:30 EST 1987 - 10:30 %H:%M Tue Sep 23 10:30:00 EDT 1986 - 13:30 %H:%M Mon Sep 22 13:30:00 EDT 1986 + Calling `mktime' also sets the variable `tzname' with information + about the current time zone. *Note Time Zone Functions::. - The return value of the function is a pointer to a static variable - of type `struct tm', or a null pointer if an error occurred.

Note that it is the inverse of the `localtime' + function. - The `errno' variable is _not_ changed. Error conditions are - stored in the global variable `getdate_err'. See the description - above for a list of the possible error values. + *Portability note:* `mktime' is essentially universally + available. `timelocal' is rather rare. - _Warning:_ The `getdate' function should _never_ be used in - SUID-programs. The reason is obvious: using the `DATEMSK' - environment variable you can get the function to open any - arbitrary file and chances are high that with some bogus input - (such as a binary file) the program will crash. - - Function: int getdate_r (const char *STRING, struct tm *TP) - The `getdate_r' function is the reentrant counterpart of - `getdate'. It does not use the global variable `getdate_err' to - signal an error, but instead returns an error code. The same error - codes as described in the `getdate_err' documentation above are - used, with 0 meaning success. + - Function: time_t timegm (struct tm *BROKENTIME) + `timegm' is functionally identical to `mktime' except it always + takes the input values to be Coordinated Universal Time (UTC) + regardless of any local time zone setting. - Moreover, `getdate_r' stores the broken-down time in the variable - of type `struct tm' pointed to by the second argument, rather than - in a static variable. + Note that `timegm' is the inverse of `gmtime'. - This function is not defined in the Unix standard. Nevertheless - it is available on some other Unix systems as well. + *Portability note:* `mktime' is essentially universally + available. `timegm' is rather rare. For the most portable + conversion from a UTC broken-down time to a simple time, set the + `TZ' environment variable to UTC, call `mktime', then set `TZ' + back. - The warning against using `getdate' in SUID-programs applies to - `getdate_r' as well.  -File: libc.info, Node: TZ Variable, Next: Time Zone Functions, Prev: Parsing Date and Time, Up: Calendar Time - -Specifying the Time Zone with `TZ' ----------------------------------- - - In POSIX systems, a user can specify the time zone by means of the -`TZ' environment variable. For information about how to set -environment variables, see *Note Environment Variables::.

You might -set `TZ' if you are using a computer over a network from a different -time zone, and would like times reported to you in the time zone local -to you, rather than what is local to the computer. - - In POSIX.1 systems the value of the `TZ' variable can be in one of -three formats. With the GNU C library, the most common format is the -last one, which can specify a selection from a large database of time -zone information for many regions of the world. The first two formats -are used to describe the time zone information directly, which is both -more cumbersome and less precise. But the POSIX.1 standard only -specifies the details of the first two formats, so it is good to be -familiar with them in case you come across a POSIX.1 system that doesn't -support a time zone information database. +File: libc.info, Node: High Accuracy Clock, Next: Formatting Calendar Time, Prev: Broken-down Time, Up: Calendar Time - The first format is used when there is no Daylight Saving Time (or -summer time) in the local time zone: +High Accuracy Clock +------------------- - STD OFFSET + The `ntp_gettime' and `ntp_adjtime' functions provide an interface +to monitor and manipulate the system clock to maintain high accuracy +time. For example, you can fine tune the speed of the clock or +synchronize it with another time source. - The STD string specifies the name of the time zone. It must be -three or more characters long and must not contain a leading colon, -embedded digits, commas, nor plus and minus signs. There is no space -character separating the time zone name from the OFFSET, so these -restrictions are necessary to parse the specification correctly. + A typical use of these functions is by a server implementing the +Network Time Protocol to synchronize the clocks of multiple systems and +high precision clocks. - The OFFSET specifies the time value you must add to the local time -to get a Coordinated Universal Time value. It has syntax like -[`+'|`-']HH[`:'MM[`:'SS]]. This is positive if the local time zone is -west of the Prime Meridian and negative if it is east. The hour must -be between `0' and `23', and the minute and seconds between `0' and -`59'. + These functions are declared in `sys/timex.h'. - For example, here is how we would specify Eastern Standard Time, but -without any Daylight Saving Time alternative: + - Data Type: struct ntptimeval + This structure is used for information about the system clock. It + contains the following members: + `struct timeval time' + This is the current calendar time, expressed as the elapsed + time since the epoch. The `struct timeval' data type is + described in *Note Elapsed Time::. - EST+5 + `long int maxerror' + This is the maximum error, measured in microseconds. Unless + updated via `ntp_adjtime' periodically, this value will reach + some platform-specific maximum value. - The second format is used when there is Daylight Saving Time: + `long int esterror' + This is the estimated error, measured in microseconds. This + value can be set by `ntp_adjtime' to indicate the estimated + offset of the system clock from the true calendar time. - STD OFFSET DST [OFFSET]`,'START[`/'TIME]`,'END[`/'TIME] + - Function: int ntp_gettime (struct ntptimeval *TPTR) + The `ntp_gettime' function sets the structure pointed to by TPTR + to current values. The elements of the structure afterwards + contain the values the timer implementation in the kernel assumes. + They might or might not be correct. If they are not a + `ntp_adjtime' call is necessary. - The initial STD and OFFSET specify the standard time zone, as -described above. The DST string and OFFSET specify the name and offset -for the corresponding Daylight Saving Time zone; if the OFFSET is -omitted, it defaults to one hour ahead of standard time. + The return value is `0' on success and other values on failure. + The following `errno' error conditions are defined for this + function: - The remainder of the specification describes when Daylight Saving -Time is in effect. The START field is when Daylight Saving Time goes -into effect and the END field is when the change is made back to -standard time. The following formats are recognized for these fields: + `TIME_ERROR' + The precision clock model is not properly set up at the + moment, thus the clock must be considered unsynchronized, and + the values should be treated with care. -`JN' - This specifies the Julian day, with N between `1' and `365'. - February 29 is never counted, even in leap years. + - Data Type: struct timex + This structure is used to control and monitor the system clock. It + contains the following members: + `unsigned int modes' + This variable controls whether and which values are set. + Several symbolic constants have to be combined with _binary + or_ to specify the effective mode. These constants start + with `MOD_'. -`N' - This specifies the Julian day, with N between `0' and `365'. - February 29 is counted in leap years. + `long int offset' + This value indicates the current offset of the system clock + from the true calendar time. The value is given in + microseconds. If bit `MOD_OFFSET' is set in `modes', the + offset (and possibly other dependent values) can be set. The + offset's absolute value must not exceed `MAXPHASE'. -`MM.W.D' - This specifies day D of week W of month M. The day D must be - between `0' (Sunday) and `6'. The week W must be between `1' and - `5'; week `1' is the first week in which day D occurs, and week - `5' specifies the _last_ D day in the month. The month M should be - between `1' and `12'. + `long int frequency' + This value indicates the difference in frequency between the + true calendar time and the system clock. The value is + expressed as scaled PPM (parts per million, 0.0001%). The + scaling is `1 << SHIFT_USEC'. The value can be set with bit + `MOD_FREQUENCY', but the absolute value must not exceed + `MAXFREQ'. - The TIME fields specify when, in the local time currently in effect, -the change to the other time occurs. If omitted, the default is -`02:00:00'. + `long int maxerror' + This is the maximum error, measured in microseconds. A new + value can be set using bit `MOD_MAXERROR'. Unless updated via + `ntp_adjtime' periodically, this value will increase steadily + and reach some platform-specific maximum value. - For example, here is how you would specify the Eastern time zone in -the United States, including the appropriate Daylight Saving Time and -its dates of applicability. The normal offset from UTC is 5 hours; -since this is west of the prime meridian, the sign is positive. Summer -time begins on the first Sunday in April at 2:00am, and ends on the -last Sunday in October at 2:00am. + `long int esterror' + This is the estimated error, measured in microseconds. This + value can be set using bit `MOD_ESTERROR'. - EST+5EDT,M4.1.0/2,M10.5.0/2 + `int status' + This variable reflects the various states of the clock + machinery. There are symbolic constants for the significant + bits, starting with `STA_'. Some of these flags can be + updated using the `MOD_STATUS' bit. - The schedule of Daylight Saving Time in any particular jurisdiction -has changed over the years. To be strictly correct, the conversion of -dates and times in the past should be based on the schedule that was in -effect then. However, this format has no facilities to let you specify -how the schedule has changed from year to year. The most you can do is -specify one particular schedule--usually the present day schedule--and -this is used to convert any date, no matter when. For precise time zone -specifications, it is best to use the time zone information database -(see below). + `long int constant' + This value represents the bandwidth or stiffness of the PLL + (phase locked loop) implemented in the kernel. The value can + be changed using bit `MOD_TIMECONST'. - The third format looks like this: + `long int precision' + This value represents the accuracy or the maximum error when + reading the system clock. The value is expressed in + microseconds. - :CHARACTERS + `long int tolerance' + This value represents the maximum frequency error of the + system clock in scaled PPM. This value is used to increase + the `maxerror' every second. - Each operating system interprets this format differently; in the GNU -C library, CHARACTERS is the name of a file which describes the time -zone. + `struct timeval time' + The current calendar time. - If the `TZ' environment variable does not have a value, the -operation chooses a time zone by default. In the GNU C library, the -default time zone is like the specification `TZ=:/etc/localtime' (or -`TZ=:/usr/local/etc/localtime', depending on how GNU C library was -configured; *note Installation::). Other C libraries use their own -rule for choosing the default time zone, so there is little we can say -about them. + `long int tick' + The elapsed time between clock ticks in microseconds. A + clock tick is a periodic timer interrupt on which the system + clock is based. - If CHARACTERS begins with a slash, it is an absolute file name; -otherwise the library looks for the file -`/share/lib/zoneinfo/CHARACTERS'. The `zoneinfo' directory contains -data files describing local time zones in many different parts of the -world. The names represent major cities, with subdirectories for -geographical areas; for example, `America/New_York', `Europe/London', -`Asia/Hong_Kong'. These data files are installed by the system -administrator, who also sets `/etc/localtime' to point to the data file -for the local time zone. The GNU C library comes with a large database -of time zone information for most regions of the world, which is -maintained by a community of volunteers and put in the public domain. + `long int ppsfreq' + This is the first of a few optional variables that are + present only if the system clock can use a PPS (pulse per + second) signal to discipline the system clock.

They do this by setting a -timer; when the timer expires, the process receives a signal. + The functions described in this section format calendar time values +as strings. These functions are declared in the header file `time.h'. - Each process has three independent interval timers available: + - Function: char * asctime (const struct tm *BROKENTIME) + The `asctime' function converts the broken-down time value that + BROKENTIME points to into a string in a standard format: - * A real-time timer that counts elapsed time. This timer sends a - `SIGALRM' signal to the process when it expires. + "Tue May 21 13:46:22 1991\n" - * A virtual timer that counts processor time used by the process. - This timer sends a `SIGVTALRM' signal to the process when it - expires. + The abbreviations for the days of week are: `Sun', `Mon', `Tue', + `Wed', `Thu', `Fri', and `Sat'. - * A profiling timer that counts both processor time used by the - process, and processor time spent in system calls on behalf of the - process. This timer sends a `SIGPROF' signal to the process when - it expires. + The abbreviations for the months are: `Jan', `Feb', `Mar', `Apr', + `May', `Jun', `Jul', `Aug', `Sep', `Oct', `Nov', and `Dec'. - This timer is useful for profiling in interpreters. The interval - timer mechanism does not have the fine granularity necessary for - profiling native code. + The return value points to a statically allocated string, which + might be overwritten by subsequent calls to `asctime' or `ctime'. + (But no other library function overwrites the contents of this + string.) - You can only have one timer of each kind set at any given time. If -you set a timer that has not yet expired, that timer is simply reset to -the new value. + - Function: char * asctime_r (const struct tm *BROKENTIME, char + *BUFFER) + This function is similar to `asctime' but instead of placing the + result in a static buffer it writes the string in the buffer + pointed to by the parameter BUFFER. This buffer should have room + for at least 26 bytes, including the terminating null. - You should establish a handler for the appropriate alarm signal using -`signal' or `sigaction' before issuing a call to `setitimer' or -`alarm'. Otherwise, an unusual chain of events could cause the timer -to expire before your program establishes the handler. In this case it -would be terminated, since termination is the default action for the -alarm signals. *Note Signal Handling::. + If no error occurred the function returns a pointer to the string + the result was written into, i.e., it returns BUFFER. Otherwise + return `NULL'. - The `setitimer' function is the primary means for setting an alarm. -This facility is declared in the header file `sys/time.h'. The `alarm' -function, declared in `unistd.h', provides a somewhat simpler interface -for setting the real-time timer. + - Function: char * ctime (const time_t *TIME) + The `ctime' function is similar to `asctime', except that you + specify the calendar time argument as a `time_t' simple time value + rather than in broken-down local time format. It is equivalent to - - Data Type: struct itimerval - This structure is used to specify when a timer should expire.

If - zero, the alarm will only be sent once. + asctime (localtime (TIME)) - `struct timeval it_value' - This is the period between now and the first timer interrupt. - If zero, the alarm is disabled. + `ctime' sets the variable `tzname', because `localtime' does so. + *Note Time Zone Functions::. - The `struct timeval' data type is described in *Note Elapsed - Time::. + - Function: char * ctime_r (const time_t *TIME, char *BUFFER) + This function is similar to `ctime', but places the result in the + string pointed to by BUFFER. It is equivalent to (written using + gcc extensions, *note Statement Exprs: (gcc)Statement Exprs.): - - Function: int setitimer (int WHICH, struct itimerval *NEW, struct - itimerval *OLD) - The `setitimer' function sets the timer specified by WHICH - according to NEW.

Numbers that do not have a range indicated below + are never padded, since there is no natural width for them. - - Function: unsigned int alarm (unsigned int SECONDS) - The `alarm' function sets the real-time timer to expire in SECONDS - seconds.

This is specified in decimal notation.

If you have established a handler for -`SIGALRM' signals and a `SIGALRM' signal is delivered while the process -is sleeping, the action taken might be just to cause `sleep' to return -instead of invoking your handler. And, if `sleep' is interrupted by -delivery of a signal whose handler requests an alarm or alters the -handling of `SIGALRM', this handler and `sleep' will interfere. + `%e' + The day of the month like with `%d', but padded with blank + (range ` 1' through `31'). - On the GNU system, it is safe to use `sleep' and `SIGALRM' in the -same program, because `sleep' does not work by means of `SIGALRM'. + This format is a POSIX.2 extension and also appears in + ISO C99. - - Function: int nanosleep (const struct timespec *REQUESTED_TIME, - struct timespec *REMAINING) - If resolution to seconds is not enough the `nanosleep' function can - be used.

When the -process tries to exceed a limit, it may get a signal, or the system call -by which it tried to do so may fail, depending on the resource. Each -process initially inherits its limit values from its parent, but it can -subsequently change them. +Convert textual time and date information back +---------------------------------------------- - There are two per-process limits associated with a resource: + The ISO C standard does not specify any functions which can convert +the output of the `strftime' function back into a binary format. This +led to a variety of more-or-less successful implementations with +different interfaces over the years. Then the Unix standard was +extended by the addition of two functions: `strptime' and `getdate'. +Both have strange interfaces but at least they are widely available. -"current limit" - The current limit is the value the system will not allow usage to - exceed. It is also called the "soft limit" because the process - being limited can generally raise the current limit at will. +* Menu: -"maximum limit" - The maximum limit is the maximum value to which a process is - allowed to set its current limit. It is also called the "hard - limit" because there is no way for a process to get around it. A - process may lower its own maximum limit, but only the superuser - may increase a maximum limit. +* Low-Level Time String Parsing:: Interpret string according to given format. +* General Time String Parsing:: User-friendly function to parse data and + time strings. - The symbols for use with `getrlimit', `setrlimit', `getrlimit64', -and `setrlimit64' are defined in `sys/resource.h'. + +File: libc.info, Node: Low-Level Time String Parsing, Next: General Time String Parsing, Up: Parsing Date and Time - - Function: int getrlimit (int RESOURCE, struct rlimit *RLP) - Read the current and maximum limits for the resource RESOURCE and - store them in `*RLP'. +Interpret string according to given format +.......................................... - The return value is `0' on success and `-1' on failure. The only - possible `errno' error condition is `EFAULT'. + he first function is rather low-level. It is nevertheless frequently +used in software since it is better known. Its interface and +implementation are heavily influenced by the `getdate' function, which +is defined and implemented in terms of calls to `strptime'. - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `getrlimit64'. Thus, the - LFS interface transparently replaces the old interface. + - Function: char * strptime (const char *S, const char *FMT, struct tm + *TP) + The `strptime' function parses the input string S according to the + format string FMT and stores its results in the structure TP. - - Function: int getrlimit64 (int RESOURCE, struct rlimit64 *RLP) - This function is similar to `getrlimit' but its second parameter is - a pointer to a variable of type `struct rlimit64', which allows it - to read values which wouldn't fit in the member of a `struct - rlimit'. + The input string could be generated by a `strftime' call or + obtained any other way. It does not need to be in a + human-recognizable format; e.g. a date passed as `"02:1999:9"' is + acceptable, even though it is ambiguous without context. As long + as the format string FMT matches the input string the function + will succeed. - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit machine, this function is available under the name - `getrlimit' and so transparently replaces the old interface. + The user has to make sure, though, that the input can be parsed in + a unambiguous way. The string `"1999112"' can be parsed using the + format `"%Y%m%d"' as 1999-1-12, 1999-11-2, or even 19991-1-2. It + is necessary to add appropriate separators to reliably get results. - - Function: int setrlimit (int RESOURCE, const struct rlimit *RLP) - Store the current and maximum limits for the resource RESOURCE in - `*RLP'. + The format string consists of the same components as the format + string of the `strftime' function. The only difference is that + the flags `_', `-', `0', and `^' are not allowed. Several of the + distinct formats of `strftime' do the same work in `strptime' + since differences like case of the input do not matter. For + reasons of symmetry all formats are supported, though. - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is possible: + The modifiers `E' and `O' are also allowed everywhere the + `strftime' function allows them. - `EPERM' - * The process tried to raise a current limit beyond the - maximum limit. + The formats are: - * The process tried to raise a maximum limit, but is not - superuser. + `%a' + `%A' + The weekday name according to the current locale, in + abbreviated form or the full name. - When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit system this function is in fact `setrlimit64'. Thus, the - LFS interface transparently replaces the old interface. + `%b' + `%B' + `%h' + The month name according to the current locale, in + abbreviated form or the full name. - - Function: int setrlimit64 (int RESOURCE, const struct rlimit64 *RLP) - This function is similar to `setrlimit' but its second parameter is - a pointer to a variable of type `struct rlimit64' which allows it - to set values which wouldn't fit in the member of a `struct - rlimit'. + `%c' + The date and time representation for the current locale. - If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a - 32-bit machine this function is available under the name - `setrlimit' and so transparently replaces the old interface. + `%Ec' + Like `%c' but the locale's alternative date and time format + is used. - - Data Type: struct rlimit - This structure is used with `getrlimit' to receive limit values, - and with `setrlimit' to specify limit values for a particular - process and resource. It has two fields: + `%C' + The century of the year. - `rlim_t rlim_cur' - The current limit + It makes sense to use this format only if the format string + also contains the `%y' format. - `rlim_t rlim_max' - The maximum limit. + `%EC' + The locale's representation of the period. - For `getrlimit', the structure is an output; it receives the - current values. For `setrlimit', it specifies the new values. + Unlike `%C' it sometimes makes sense to use this format since + some cultures represent years relative to the beginning of + eras instead of using the Gregorian years. - For the LFS functions a similar type is defined in `sys/resource.h'. + `%d' - - Data Type: struct rlimit64 - This structure is analogous to the `rlimit' structure above, but - its components have wider ranges. It has two fields: + `%e' + The day of the month as a decimal number (range `1' through + `31').

Bear in mind, though, that CPU time is not the -only resource a process uses or that processes contend for. In some -cases, it is not even particularly important. Giving a process a high -"priority" may have very little effect on how fast a process runs with -respect to other processes. The priorities discussed in this section -apply only to CPU time. + Leading zeroes are permitted but not required. - CPU scheduling is a complex issue and different systems do it in -wildly different ways. New ideas continually develop and find their -way into the intricacies of the various systems' scheduling algorithms. -This section discusses the general concepts, some specifics of systems -that commonly use the GNU C library, and some standards. + _Note:_ Currently, this is not fully implemented.

The format + is recognized, input is consumed but no field in TM is set. - Every process has an absolute priority, and it is represented by a -number. The higher the number, the higher the absolute priority. + `%w' + The day of the week as a decimal number (range `0' through + `6'), Sunday being `0'. - On systems of the past, and most systems today, all processes have -absolute priority 0 and this section is irrelevant.

This is true -even if the process with the lower priority is already using the CPU -(i.e. the scheduling is preemptive). Of course, we're only talking -about processes that are running or "ready to run," which means they are -ready to execute instructions right now. When a process blocks to wait -for something like I/O, its absolute priority is irrelevant. + _Note:_ Currently, this is not fully implemented.

In that case, who gets the -CPU is determined by the scheduling policy. If the processes have -absolute priority 0, the traditional scheduling policy described in -*Note Traditional Scheduling:: applies. Otherwise, the policies -described in *Note Realtime Scheduling:: apply. + `%W' + The week number of the current year as a decimal number + (range `0' through `53'). - You normally give an absolute priority above 0 only to a process that -can be trusted not to hog the CPU. Such processes are designed to block -(or terminate) after relatively short CPU runs. + Leading zeroes are permitted but not required. - A process begins life with the same absolute priority as its parent -process. Functions described in *Note Basic Scheduling Functions:: can -change it. + _Note:_ Currently, this is not fully implemented.

Only a privileged process or the target -process' owner can change its absolute priority at all. + `%OW' + Same as `%W' but using the locale's alternative numeric + symbols. - POSIX requires absolute priority values used with the realtime -scheduling policies to be consecutive with a range of at least 32. On -Linux, they are 1 through 99. The functions `sched_get_priority_max' -and `sched_set_priority_min' portably tell you what the range is on a -particular system. + `%x' + The date using the locale's date format. -Using Absolute Priority -....................... + `%Ex' + Like `%x' but the locale's alternative data representation is + used. - One thing you must keep in mind when designing real time -applications is that having higher absolute priority than any other -process doesn't guarantee the process can run continuously. Two things -that can wreck a good CPU run are interrupts and page faults. + `%X' + The time using the locale's time format. - Interrupt handlers live in that limbo between processes. The CPU is -executing instructions, but they aren't part of any process. An -interrupt will stop even the highest priority process. So you must -allow for slight delays and make sure that no device in the system has -an interrupt handler that could cause too long a delay between -instructions for your process. + `%EX' + Like `%X' but the locale's alternative time representation is + used. - Similarly, a page fault causes what looks like a straightforward -sequence of instructions to take a long time. The fact that other -processes get to run while the page faults in is of no consequence, -because as soon as the I/O is complete, the high priority process will -kick them out and run again, but the wait for the I/O itself could be a -problem. To neutralize this threat, use `mlock' or `mlockall'. + `%y' + The year without a century as a decimal number (range `0' + through `99'). - There are a few ramifications of the absoluteness of this priority -on a single-CPU system that you need to keep in mind when you choose to -set a priority and also when you're working on a program that runs with -high absolute priority. Consider a process that has higher absolute -priority than any other process in the system and due to a bug in its -program, it gets into an infinite loop. It will never cede the CPU. -You can't run a command to kill it because your command would need to -get the CPU in order to run. The errant program is in complete -control. It controls the vertical, it controls the horizontal. + Leading zeroes are permitted but not required. - There are two ways to avoid this: 1) keep a shell running somewhere -with a higher absolute priority. 2) keep a controlling terminal -attached to the high priority process group. All the priority in the -world won't stop an interrupt handler from running and delivering a -signal to the process if you hit Control-C. + Note that it is questionable to use this format without the + `%C' format. The `strptime' function does regard input + values in the range 68 to 99 as the years 1969 to 1999 and + the values 0 to 68 as the years 2000 to 2068. But maybe this + heuristic fails for some input data. - Some systems use absolute priority as a means of allocating a fixed -percentage of CPU time to a process. To do this, a super high priority -privileged process constantly monitors the process' CPU usage and raises -its absolute priority when the process isn't getting its entitled share -and lowers it when the process is exceeding it. + Therefore it is best to avoid `%y' completely and use `%Y' + instead. - *Note:* The absolute priority is sometimes called the "static -priority." We don't use that term in this manual because it misses the -most important feature of the absolute priority: its absoluteness. + `%Ey' + The offset from `%EC' in the locale's alternative + representation. - -File: libc.info, Node: Realtime Scheduling, Next: Basic Scheduling Functions, Prev: Absolute Priority, Up: Priority + `%Oy' + The offset of the year (from `%C') using the locale's + alternative numeric symbols. -Realtime Scheduling -------------------- + `%Y' + The year as a decimal number, using the Gregorian calendar. - Whenever two processes with the same absolute priority are ready to -run, the kernel has a decision to make, because only one can run at a -time. If the processes have absolute priority 0, the kernel makes this -decision as described in *Note Traditional Scheduling::. Otherwise, -the decision is as described in this section. + `%EY' + The full alternative year representation. - If two processes are ready to run but have different absolute -priorities, the decision is much simpler, and is described in *Note -Absolute Priority::. + `%z' + The offset from GMT in ISO 8601/RFC822 format. - Each process has a scheduling policy. For processes with absolute -priority other than zero, there are two available: + `%Z' + The timezone name. - 1. First Come First Served + _Note:_ Currently, this is not fully implemented. The format + is recognized, input is consumed but no field in TM is set. - 2. Round Robin + `%%' + A literal `%' character. - The most sensible case is where all the processes with a certain -absolute priority have the same scheduling policy. We'll discuss that -first. + All other characters in the format string must have a matching + character in the input string. Exceptions are white spaces in the + input string which can match zero or more white space characters + in the format string. - In Round Robin, processes share the CPU, each one running for a small -quantum of time ("time slice") and then yielding to another in a -circular fashion. Of course, only processes that are ready to run and -have the same absolute priority are in this circle. + The `strptime' function processes the input string from right to + left. Each of the three possible input elements (white space, + literal, or format) are handled one after the other. If the input + cannot be matched to the format string the function stops. The + remainder of the format and input strings are not processed. - In First Come First Served, the process that has been waiting the -longest to run gets the CPU, and it keeps it until it voluntarily -relinquishes the CPU, runs out of things to do (blocks), or gets -preempted by a higher priority process. + The function returns a pointer to the first character it was + unable to process. If the input string contains more characters + than required by the format string the return value points right + after the last consumed input character. If the whole input + string is consumed the return value points to the `NULL' byte at + the end of the string. If an error occurs, i.e. `strptime' fails + to match all of the format string, the function returns `NULL'. - First Come First Served, along with maximal absolute priority and -careful control of interrupts and page faults, is the one to use when a -process absolutely, positively has to run at full CPU speed or not at -all. + The specification of the function in the XPG standard is rather +vague, leaving out a few important pieces of information. Most +importantly, it does not specify what happens to those elements of TM +which are not directly initialized by the different formats. The +implementations on different Unix systems vary here. - Judicious use of `sched_yield' function invocations by processes -with First Come First Served scheduling policy forms a good compromise -between Round Robin and First Come First Served. + The GNU libc implementation does not touch those fields which are not +directly initialized. Exceptions are the `tm_wday' and `tm_yday' +elements, which are recomputed if any of the year, month, or date +elements changed. This has two implications: - To understand how scheduling works when processes of different -scheduling policies occupy the same absolute priority, you have to know -the nitty gritty details of how processes enter and exit the ready to -run list: + * Before calling the `strptime' function for a new input string, you + should prepare the TM structure you pass. Normally this will mean + initializing all values are to zero. Alternatively, you can set + all fields to values like `INT_MAX', allowing you to determine + which elements were set by the function call. Zero does not work + here since it is a valid value for many of the fields. - In both cases, the ready to run list is organized as a true queue, -where a process gets pushed onto the tail when it becomes ready to run -and is popped off the head when the scheduler decides to run it. Note -that ready to run and running are two mutually exclusive states. When -the scheduler runs a process, that process is no longer ready to run -and no longer in the ready to run list. When the process stops -running, it may go back to being ready to run again. + Careful initialization is necessary if you want to find out + whether a certain field in TM was initialized by the function call. - The only difference between a process that is assigned the Round -Robin scheduling policy and a process that is assigned First Come First -Serve is that in the former case, the process is automatically booted -off the CPU after a certain amount of time. When that happens, the -process goes back to being ready to run, which means it enters the -queue at the tail. The time quantum we're talking about is small. -Really small. This is not your father's timesharing. For example, -with the Linux kernel, the round robin time slice is a thousand times -shorter than its typical time slice for traditional scheduling. + * You can construct a `struct tm' value with several consecutive + `strptime' calls. A useful application of this is e.g. the parsing + of two separate strings, one containing date information and the + other time information. By parsing one after the other without + clearing the structure in-between, you can construct a complete + broken-down time. - A process begins life with the same scheduling policy as its parent -process. Functions described in *Note Basic Scheduling Functions:: can -change it. + The following example shows a function which parses a string which is +contains the date information in either US style or ISO 8601 form: - Only a privileged process can set the scheduling policy of a process -that has absolute priority higher than 0. + const char * + parse_date (const char *input, struct tm *tm) + { + const char *cp; + + /* First clear the result structure. */ + memset (tm, '\0', sizeof (*tm)); + + /* Try the ISO format first. */ + cp = strptime (input, "%F", tm); + if (cp == NULL) + { + /* Does not match.

Otherwise, it is `-1' and - `ERRNO' is set accordingly. The `errno' values specific to this - function are: + In POSIX systems, a user can specify the time zone by means of the +`TZ' environment variable.

You might +set `TZ' if you are using a computer over a network from a different +time zone, and would like times reported to you in the time zone local +to you, rather than what is local to the computer. - `EINVAL' - PID is negative. + In POSIX.1 systems the value of the `TZ' variable can be in one of +three formats. With the GNU C library, the most common format is the +last one, which can specify a selection from a large database of time +zone information for many regions of the world. The first two formats +are used to describe the time zone information directly, which is both +more cumbersome and less precise. But the POSIX.1 standard only +specifies the details of the first two formats, so it is good to be +familiar with them in case you come across a POSIX.1 system that doesn't +support a time zone information database. + The first format is used when there is no Daylight Saving Time (or +summer time) in the local time zone: - - Function: int sched_get_priority_min (int *POLICY); - This function returns the lowest absolute priority value that is - allowable for a process with scheduling policy POLICY. + STD OFFSET - On Linux, it is 0 for SCHED_OTHER and 1 for everything else. + The STD string specifies the name of the time zone. It must be +three or more characters long and must not contain a leading colon, +embedded digits, commas, nor plus and minus signs. There is no space +character separating the time zone name from the OFFSET, so these +restrictions are necessary to parse the specification correctly. - On success, the return value is `0'. Otherwise, it is `-1' and - `ERRNO' is set accordingly. The `errno' values specific to this - function are: + The OFFSET specifies the time value you must add to the local time +to get a Coordinated Universal Time value. It has syntax like +[`+'|`-']HH[`:'MM[`:'SS]]. This is positive if the local time zone is +west of the Prime Meridian and negative if it is east. The hour must +be between `0' and `23', and the minute and seconds between `0' and +`59'. - `EINVAL' - POLICY does not identify an existing scheduling policy. + For example, here is how we would specify Eastern Standard Time, but +without any Daylight Saving Time alternative: + EST+5 - - Function: int sched_get_priority_max (int *POLICY); - This function returns the highest absolute priority value that is - allowable for a process that with scheduling policy POLICY. + The second format is used when there is Daylight Saving Time: - On Linux, it is 0 for SCHED_OTHER and 99 for everything else. + STD OFFSET DST [OFFSET]`,'START[`/'TIME]`,'END[`/'TIME] - On success, the return value is `0'. Otherwise, it is `-1' and - `ERRNO' is set accordingly. The `errno' values specific to this - function are: + The initial STD and OFFSET specify the standard time zone, as +described above. The DST string and OFFSET specify the name and offset +for the corresponding Daylight Saving Time zone; if the OFFSET is +omitted, it defaults to one hour ahead of standard time. - `EINVAL' - POLICY does not identify an existing scheduling policy. + The remainder of the specification describes when Daylight Saving +Time is in effect. The START field is when Daylight Saving Time goes +into effect and the END field is when the change is made back to +standard time. The following formats are recognized for these fields: +`JN' + This specifies the Julian day, with N between `1' and `365'. + February 29 is never counted, even in leap years. - - Function: int sched_rr_get_interval (pid_t PID, struct timespec - *INTERVAL) - This function returns the length of the quantum (time slice) used - with the Round Robin scheduling policy, if it is used, for the - process with Process ID PID. +`N' + This specifies the Julian day, with N between `0' and `365'. + February 29 is counted in leap years. - It returns the length of time as INTERVAL. +`MM.W.D' + This specifies day D of week W of month M. The day D must be + between `0' (Sunday) and `6'. The week W must be between `1' and + `5'; week `1' is the first week in which day D occurs, and week + `5' specifies the _last_ D day in the month. The month M should be + between `1' and `12'. - With a Linux kernel, the round robin time slice is always 150 - microseconds, and PID need not even be a real pid. + The TIME fields specify when, in the local time currently in effect, +the change to the other time occurs. If omitted, the default is +`02:00:00'. - The return value is `0' on success and in the pathological case - that it fails, the return value is `-1' and `errno' is set - accordingly. There is nothing specific that can go wrong with this - function, so there are no specific `errno' values. + For example, here is how you would specify the Eastern time zone in +the United States, including the appropriate Daylight Saving Time and +its dates of applicability. The normal offset from UTC is 5 hours; +since this is west of the prime meridian, the sign is positive. Summer +time begins on the first Sunday in April at 2:00am, and ends on the +last Sunday in October at 2:00am. + EST+5EDT,M4.1.0/2,M10.5.0/2 - - Function: int sched_yield (void) - This function voluntarily gives up the process' claim on the CPU. + The schedule of Daylight Saving Time in any particular jurisdiction +has changed over the years. To be strictly correct, the conversion of +dates and times in the past should be based on the schedule that was in +effect then. However, this format has no facilities to let you specify +how the schedule has changed from year to year. The most you can do is +specify one particular schedule--usually the present day schedule--and +this is used to convert any date, no matter when. For precise time zone +specifications, it is best to use the time zone information database +(see below). - Technically, `sched_yield' causes the calling process to be made - immediately ready to run (as opposed to running, which is what it - was before). This means that if it has absolute priority higher - than 0, it gets pushed onto the tail of the queue of processes - that share its absolute priority and are ready to run, and it will - run again when its turn next arrives. If its absolute priority is - 0, it is more complicated, but still has the effect of yielding - the CPU to other processes. + The third format looks like this: - If there are no other processes that share the calling process' - absolute priority, this function doesn't have any effect. + :CHARACTERS - To the extent that the containing program is oblivious to what - other processes in the system are doing and how fast it executes, - this function appears as a no-op. + Each operating system interprets this format differently; in the GNU +C library, CHARACTERS is the name of a file which describes the time +zone. - The return value is `0' on success and in the pathological case - that it fails, the return value is `-1' and `errno' is set - accordingly. There is nothing specific that can go wrong with this - function, so there are no specific `errno' values. + If the `TZ' environment variable does not have a value, the +operation chooses a time zone by default. In the GNU C library, the +default time zone is like the specification `TZ=:/etc/localtime' (or +`TZ=:/usr/local/etc/localtime', depending on how GNU C library was +configured; *note Installation::). Other C libraries use their own +rule for choosing the default time zone, so there is little we can say +about them. + If CHARACTERS begins with a slash, it is an absolute file name; +otherwise the library looks for the file +`/share/lib/zoneinfo/CHARACTERS'. The `zoneinfo' directory contains +data files describing local time zones in many different parts of the +world. The names represent major cities, with subdirectories for +geographical areas; for example, `America/New_York', `Europe/London', +`Asia/Hong_Kong'. These data files are installed by the system +administrator, who also sets `/etc/localtime' to point to the data file +for the local time zone. The GNU C library comes with a large database +of time zone information for most regions of the world, which is +maintained by a community of volunteers and put in the public domain.  -File: libc.info, Node: Traditional Scheduling, Prev: Basic Scheduling Functions, Up: Priority - -Traditional Scheduling ----------------------- - - This section is about the scheduling among processes whose absolute -priority is 0.

If multiple abbreviations have been used + (e.g. `"EWT"' and `"EDT"' for U.S. Eastern War Time and Eastern + Daylight Time), the array contains the most recent abbreviation. -Introduction To Traditional Scheduling -...................................... + The `tzname' array is required for POSIX.1 compatibility, but in + GNU programs it is better to use the `tm_zone' member of the + broken-down time structure, since `tm_zone' reports the correct + abbreviation even when it is not the latest one. - Long before there was absolute priority (See *Note Absolute -Priority::), Unix systems were scheduling the CPU using this system. -When Posix came in like the Romans and imposed absolute priorities to -accommodate the needs of realtime processing, it left the indigenous -Absolute Priority Zero processes to govern themselves by their own -familiar scheduling policy. + Though the strings are declared as `char *' the user must refrain + from modifying these strings. Modifying the strings will almost + certainly lead to trouble. - Indeed, absolute priorities higher than zero are not available on -many systems today and are not typically used when they are, being -intended mainly for computers that do realtime processing. So this -section describes the only scheduling many programmers need to be -concerned about. - But just to be clear about the scope of this scheduling: Any time a -process with a absolute priority of 0 and a process with an absolute -priority higher than 0 are ready to run at the same time, the one with -absolute priority 0 does not run. If it's already running when the -higher priority ready-to-run process comes into existence, it stops -immediately. + - Function: void tzset (void) + The `tzset' function initializes the `tzname' variable from the + value of the `TZ' environment variable. It is not usually + necessary for your program to call this function, because it is + called automatically when you use the other time conversion + functions that depend on the time zone. - In addition to its absolute priority of zero, every process has -another priority, which we will refer to as "dynamic priority" because -it changes over time. The dynamic priority is meaningless for -processes with an absolute priority higher than zero. + The following variables are defined for compatibility with System V +Unix. Like `tzname', these variables are set by calling `tzset' or the +other time conversion functions. - The dynamic priority sometimes determines who gets the next turn on -the CPU. Sometimes it determines how long turns last. Sometimes it -determines whether a process can kick another off the CPU. + - Variable: long int timezone + This contains the difference between UTC and the latest local + standard time, in seconds west of UTC. For example, in the U.S. + Eastern time zone, the value is `5*60*60'. Unlike the `tm_gmtoff' + member of the broken-down time structure, this value is not + adjusted for daylight saving, and its sign is reversed. In GNU + programs it is better to use `tm_gmtoff', since it contains the + correct offset even when it is not the latest one. - In Linux, the value is a combination of these things, but mostly it -is just determines the length of the time slice. The higher a process' -dynamic priority, the longer a shot it gets on the CPU when it gets one. -If it doesn't use up its time slice before giving up the CPU to do -something like wait for I/O, it is favored for getting the CPU back when -it's ready for it, to finish out its time slice. Other than that, -selection of processes for new time slices is basically round robin. -But the scheduler does throw a bone to the low priority processes: A -process' dynamic priority rises every time it is snubbed in the -scheduling process. In Linux, even the fat kid gets to play. + - Variable: int daylight + This variable has a nonzero value if Daylight Saving Time rules + apply.

A lower nice value corresponds to higher -priority for the process. These constants describe the range of -priority values: + * A real-time timer that counts elapsed time. This timer sends a + `SIGALRM' signal to the process when it expires. -`PRIO_MIN' - The lowest valid nice value. + * A virtual timer that counts processor time used by the process. + This timer sends a `SIGVTALRM' signal to the process when it + expires. -`PRIO_MAX' - The highest valid nice value. + * A profiling timer that counts both processor time used by the + process, and processor time spent in system calls on behalf of the + process. This timer sends a `SIGPROF' signal to the process when + it expires. - - Function: int getpriority (int CLASS, int ID) - Return the nice value of a set of processes; CLASS and ID specify - which ones (see below).

Before we get -into these details a few words about memory subsystems in traditional -Unix systems will be given. + The function `sleep' gives a simple way to make the program wait for +a short interval. If your program doesn't use signals (except to +terminate), then you can expect `sleep' to wait reliably throughout the +specified interval. Otherwise, `sleep' can return sooner if a signal +arrives; if you want to wait for a given interval regardless of +signals, use `select' (*note Waiting for I/O::) and don't specify any +descriptors to wait for. -* Menu: + - Function: unsigned int sleep (unsigned int SECONDS) + The `sleep' function waits for SECONDS or until a signal is + delivered, whichever happens first. -* Memory Subsystem:: Overview about traditional Unix memory handling. -* Query Memory Parameters:: How to get information about the memory - subsystem? + If `sleep' function returns because the requested interval is over, + it returns a value of zero. If it returns because of delivery of a + signal, its return value is the remaining time in the sleep + interval. - -File: libc.info, Node: Memory Subsystem, Next: Query Memory Parameters, Up: Memory Resources + The `sleep' function is declared in `unistd.h'. -Overview about traditional Unix memory handling ------------------------------------------------ + Resist the temptation to implement a sleep for a fixed amount of +time by using the return value of `sleep', when nonzero, to call +`sleep' again. This will work with a certain amount of accuracy as +long as signals arrive infrequently. But each signal can cause the +eventual wakeup time to be off by an additional second or so. Suppose a +few signals happen to arrive in rapid succession by bad luck--there is +no limit on how much this could shorten or lengthen the wait. - Unix systems normally provide processes virtual address spaces. This -means that the addresses of the memory regions do not have to correspond -directly to the addresses of the actual physical memory which stores the -data. An extra level of indirection is introduced which translates -virtual addresses into physical addresses. This is normally done by the -hardware of the processor. + Instead, compute the calendar time at which the program should stop +waiting, and keep trying to wait until that calendar time. This won't +be off by more than a second. With just a little more work, you can use +`select' and make the waiting period quite accurate. (Of course, heavy +system load can cause additional unavoidable delays--unless the machine +is dedicated to one application, there is no way you can avoid this.) - Using a virtual address space has several advantage. The most -important is process isolation. The different processes running on the -system cannot interfere directly with each other. No process can write -into the address space of another process (except when shared memory is -used but then it is wanted and controlled). + On some systems, `sleep' can do strange things if your program uses +`SIGALRM' explicitly. Even if `SIGALRM' signals are being ignored or +blocked when `sleep' is called, `sleep' might return prematurely on +delivery of a `SIGALRM' signal. If you have established a handler for +`SIGALRM' signals and a `SIGALRM' signal is delivered while the process +is sleeping, the action taken might be just to cause `sleep' to return +instead of invoking your handler. And, if `sleep' is interrupted by +delivery of a signal whose handler requests an alarm or alters the +handling of `SIGALRM', this handler and `sleep' will interfere. - Another advantage of virtual memory is that the address space the -processes see can actually be larger than the physical memory available. -The physical memory can be extended by storage on an external media -where the content of currently unused memory regions is stored. The -address translation can then intercept accesses to these memory regions -and make memory content available again by loading the data back into -memory. This concept makes it necessary that programs which have to use -lots of memory know the difference between available virtual address -space and available physical memory. If the working set of virtual -memory of all the processes is larger than the available physical memory -the system will slow down dramatically due to constant swapping of -memory content from the memory to the storage media and back. This is -called "thrashing". + On the GNU system, it is safe to use `sleep' and `SIGALRM' in the +same program, because `sleep' does not work by means of `SIGALRM'. - A final aspect of virtual memory which is important and follows from -what is said in the last paragraph is the granularity of the virtual -address space handling. When we said that the virtual address handling -stores memory content externally it cannot do this on a byte-by-byte -basis. The administrative overhead does not allow this (leaving alone -the processor hardware). Instead several thousand bytes are handled -together and form a "page". The size of each page is always a power of -two byte. The smallest page size in use today is 4096, with 8192, -16384, and 65536 being other popular sizes. + - Function: int nanosleep (const struct timespec *REQUESTED_TIME, + struct timespec *REMAINING) + If resolution to seconds is not enough the `nanosleep' function can + be used. As the name suggests the sleep interval can be specified + in nanoseconds. The actual elapsed time of the sleep interval + might be longer since the system rounds the elapsed time you + request up to the next integer multiple of the actual resolution + the system can deliver. + + *`requested_time' is the elapsed time of the interval you want to + sleep. + + The function returns as *`remaining' the elapsed time left in the + interval for which you requested to sleep. If the interval + completed without getting interrupted by a signal, this is zero. + + `struct timespec' is described in *Note Elapsed Time::. + + If the function returns because the interval is over the return + value is zero. If the function returns -1 the global variable + ERRNO is set to the following values: + + `EINTR' + The call was interrupted because a signal was delivered to + the thread.

In the case of `mmap' is it necessary to -provide a length argument which is a multiple of the page size. -Another place where the knowledge about the page size is useful is in -memory allocation.

If the total -memory requirement for the block is close (but not larger) to a multiple -of the page size the kernel's memory handling can work more effectively -since it only has to allocate memory pages which are fully used. (To do -this optimization it is necessary to know a bit about the memory -allocator which will require a bit of memory itself for each block and -this overhead must not push the total size over the page size multiple. + This chapter describes functions for examining how much of various +kinds of resources (CPU time, memory, etc.) a process has used and +getting and setting limits on future usage. - The page size traditionally was a compile time constant.

The sum of the values that would + be reported as `ru_idrss' and `ru_isrss' in `struct + rusage' - In some ways, a non-local exit is similar to using the `return' -statement to return from a function. But while `return' abandons only -a single function call, transferring control back to the point at which -it was called, a non-local exit can potentially abandon many levels of -nested function calls. + `vm_ixrss' + Shared memory. Analogous to `ru_ixrss' in `struct + rusage' - You identify return points for non-local exits by calling the -function `setjmp'. This function saves information about the execution -environment in which the call to `setjmp' appears in an object of type -`jmp_buf'. Execution of the program continues normally after the call -to `setjmp', but if an exit is later made to this return point by -calling `longjmp' with the corresponding `jmp_buf' object, control is -transferred back to the point where `setjmp' was called. The return -value from `setjmp' is used to distinguish between an ordinary return -and a return made by a call to `longjmp', so calls to `setjmp' usually -appear in an `if' statement. + `vm_maxrss' + Maximent resident set size. Analogous to `ru_maxrss' in + `struct rusage' - Here is how the example program described above might be set up: + `vm_majflt' + Major page faults. Analogous to `ru_majflt' in `struct + rusage' - #include - #include - #include - - jmp_buf main_loop; - - void - abort_to_main_loop (int status) - { - longjmp (main_loop, status); - } - - int - main (void) - { - while (1) - if (setjmp (main_loop)) - puts ("Back at main loop...."); - else - do_command (); - } - - - void - do_command (void) - { - char buffer[128]; - if (fgets (buffer, 128, stdin) == NULL) - abort_to_main_loop (-1); - else - exit (EXIT_SUCCESS); - } + `vm_minflt' + Minor page faults. Analogous to `ru_minflt' in `struct + rusage' - The function `abort_to_main_loop' causes an immediate transfer of -control back to the main loop of the program, no matter where it is -called from. + `vm_nswap' + Swap count. Analogous to `ru_nswap' in `struct rusage' - The flow of control inside the `main' function may appear a little -mysterious at first, but it is actually a common idiom with `setjmp'. -A normal call to `setjmp' returns zero, so the "else" clause of the -conditional is executed. If `abort_to_main_loop' is called somewhere -within the execution of `do_command', then it actually appears as if -the _same_ call to `setjmp' in `main' were returning a second time with -a value of `-1'. + `vm_inblk' + Disk reads. Analogous to `ru_inblk' in `struct rusage' - So, the general pattern for using `setjmp' looks something like: + `vm_oublk' + Disk writes. Analogous to `ru_oublk' in `struct rusage' - if (setjmp (BUFFER)) - /* Code to clean up after premature return. */ - ... - else - /* Code to be executed normally after setting up the return point. */ - ... + The return value is zero if the function succeeds; `-1' otherwise. + + An additional historical function for examining resource usage, +`vtimes', is supported but not documented here. It is declared in +`sys/vtimes.h'.  -File: libc.info, Node: Non-Local Details, Next: Non-Local Exits and Signals, Prev: Non-Local Intro, Up: Non-Local Exits +File: libc.info, Node: Limits on Resources, Next: Priority, Prev: Resource Usage, Up: Resource Usage And Limitation -Details of Non-Local Exits -========================== +Limiting Resource Usage +======================= - Here are the details on the functions and data structures used for -performing non-local exits. These facilities are declared in -`setjmp.h'. + You can specify limits for the resource usage of a process. When the +process tries to exceed a limit, it may get a signal, or the system call +by which it tried to do so may fail, depending on the resource. Each +process initially inherits its limit values from its parent, but it can +subsequently change them. - - Data Type: jmp_buf - Objects of type `jmp_buf' hold the state information to be - restored by a non-local exit. The contents of a `jmp_buf' - identify a specific place to return to. + There are two per-process limits associated with a resource: - - Macro: int setjmp (jmp_buf STATE) - When called normally, `setjmp' stores information about the - execution state of the program in STATE and returns zero. If - `longjmp' is later used to perform a non-local exit to this STATE, - `setjmp' returns a nonzero value. +"current limit" + The current limit is the value the system will not allow usage to + exceed. It is also called the "soft limit" because the process + being limited can generally raise the current limit at will. - - Function: void longjmp (jmp_buf STATE, int VALUE) - This function restores current execution to the state saved in - STATE, and continues execution from the call to `setjmp' that - established that return point. Returning from `setjmp' by means of - `longjmp' returns the VALUE argument that was passed to `longjmp', - rather than `0'. (But if VALUE is given as `0', `setjmp' returns - `1'). +"maximum limit" + The maximum limit is the maximum value to which a process is + allowed to set its current limit. It is also called the "hard + limit" because there is no way for a process to get around it. A + process may lower its own maximum limit, but only the superuser + may increase a maximum limit. - There are a lot of obscure but important restrictions on the use of -`setjmp' and `longjmp'. Most of these restrictions are present because -non-local exits require a fair amount of magic on the part of the C -compiler and can interact with other parts of the language in strange -ways. + The symbols for use with `getrlimit', `setrlimit', `getrlimit64', +and `setrlimit64' are defined in `sys/resource.h'. - The `setjmp' function is actually a macro without an actual function -definition, so you shouldn't try to `#undef' it or take its address. -In addition, calls to `setjmp' are safe in only the following contexts: + - Function: int getrlimit (int RESOURCE, struct rlimit *RLP) + Read the current and maximum limits for the resource RESOURCE and + store them in `*RLP'. - * As the test expression of a selection or iteration statement (such - as `if', `switch', or `while'). + The return value is `0' on success and `-1' on failure. The only + possible `errno' error condition is `EFAULT'. - * As one operand of a equality or comparison operator that appears - as the test expression of a selection or iteration statement. The - other operand must be an integer constant expression. + When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32-bit system this function is in fact `getrlimit64'. Thus, the + LFS interface transparently replaces the old interface. - * As the operand of a unary `!' operator, that appears as the test - expression of a selection or iteration statement. + - Function: int getrlimit64 (int RESOURCE, struct rlimit64 *RLP) + This function is similar to `getrlimit' but its second parameter is + a pointer to a variable of type `struct rlimit64', which allows it + to read values which wouldn't fit in the member of a `struct + rlimit'. - * By itself as an expression statement. + If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32-bit machine, this function is available under the name + `getrlimit' and so transparently replaces the old interface. - Return points are valid only during the dynamic extent of the -function that called `setjmp' to establish them. If you `longjmp' to a -return point that was established in a function that has already -returned, unpredictable and disastrous things are likely to happen. + - Function: int setrlimit (int RESOURCE, const struct rlimit *RLP) + Store the current and maximum limits for the resource RESOURCE in + `*RLP'. - You should use a nonzero VALUE argument to `longjmp'. While -`longjmp' refuses to pass back a zero argument as the return value from -`setjmp', this is intended as a safety net against accidental misuse -and is not really good programming style. + The return value is `0' on success and `-1' on failure. The + following `errno' error condition is possible: - When you perform a non-local exit, accessible objects generally -retain whatever values they had at the time `longjmp' was called. The -exception is that the values of automatic variables local to the -function containing the `setjmp' call that have been changed since the -call to `setjmp' are indeterminate, unless you have declared them -`volatile'. + `EPERM' + * The process tried to raise a current limit beyond the + maximum limit. - -File: libc.info, Node: Non-Local Exits and Signals, Next: System V contexts, Prev: Non-Local Details, Up: Non-Local Exits + * The process tried to raise a maximum limit, but is not + superuser. -Non-Local Exits and Signals -=========================== + When the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32-bit system this function is in fact `setrlimit64'. Thus, the + LFS interface transparently replaces the old interface. - In BSD Unix systems, `setjmp' and `longjmp' also save and restore -the set of blocked signals; see *Note Blocking Signals::. However, the -POSIX.1 standard requires `setjmp' and `longjmp' not to change the set -of blocked signals, and provides an additional pair of functions -(`sigsetjmp' and `siglongjmp') to get the BSD behavior. + - Function: int setrlimit64 (int RESOURCE, const struct rlimit64 *RLP) + This function is similar to `setrlimit' but its second parameter is + a pointer to a variable of type `struct rlimit64' which allows it + to set values which wouldn't fit in the member of a `struct + rlimit'. - The behavior of `setjmp' and `longjmp' in the GNU library is -controlled by feature test macros; see *Note Feature Test Macros::. The -default in the GNU system is the POSIX.1 behavior rather than the BSD -behavior. + If the sources are compiled with `_FILE_OFFSET_BITS == 64' on a + 32-bit machine this function is available under the name + `setrlimit' and so transparently replaces the old interface. - The facilities in this section are declared in the header file -`setjmp.h'. + - Data Type: struct rlimit + This structure is used with `getrlimit' to receive limit values, + and with `setrlimit' to specify limit values for a particular + process and resource. It has two fields: - - Data Type: sigjmp_buf - This is similar to `jmp_buf', except that it can also store state - information about the set of blocked signals. + `rlim_t rlim_cur' + The current limit - - Function: int sigsetjmp (sigjmp_buf STATE, int SAVESIGS) - This is similar to `setjmp'. If SAVESIGS is nonzero, the set of - blocked signals is saved in STATE and will be restored if a - `siglongjmp' is later performed with this STATE. + `rlim_t rlim_max' + The maximum limit. - - Function: void siglongjmp (sigjmp_buf STATE, int VALUE) - This is similar to `longjmp' except for the type of its STATE - argument. If the `sigsetjmp' call that set this STATE used a - nonzero SAVESIGS flag, `siglongjmp' also restores the set of - blocked signals. + For `getrlimit', the structure is an output; it receives the + current values. For `setrlimit', it specifies the new values. - -File: libc.info, Node: System V contexts, Prev: Non-Local Exits and Signals, Up: Non-Local Exits + For the LFS functions a similar type is defined in `sys/resource.h'. -Complete Context Control -======================== + - Data Type: struct rlimit64 + This structure is analogous to the `rlimit' structure above, but + its components have wider ranges. It has two fields: - The Unix standard one more set of function to control the execution -path and these functions are more powerful than those discussed in this -chapter so far. These function were part of the original System V API -and by this route were added to the Unix API. Beside on branded Unix -implementations these interfaces are not widely available. Not all -platforms and/or architectures the GNU C Library is available on provide -this interface. Use `configure' to detect the availability. + `rlim64_t rlim_cur' + This is analogous to `rlimit.rlim_cur', but with a different + type. - Similar to the `jmp_buf' and `sigjmp_buf' types used for the -variables to contain the state of the `longjmp' functions the -interfaces of interest here have an appropriate type as well. Objects -of this type are normally much larger since more information is -contained. The type is also used in a few more places as we will see. -The types and functions described in this section are all defined and -declared respectively in the `ucontext.h' header file. + `rlim64_t rlim_max' + This is analogous to `rlimit.rlim_max', but with a different + type. - - Data Type: ucontext_t - The `ucontext_t' type is defined as a structure with as least the - following elements: - `ucontext_t *uc_link' - This is a pointer to the next context structure which is used - if the context described in the current structure returns. + Here is a list of resources for which you can specify a limit. +Memory and file sizes are measured in bytes. - `sigset_t uc_sigmask' - Set of signals which are blocked when this context is used. +`RLIMIT_CPU' + The maximum amount of CPU time the process can use. If it runs for + longer than this, it gets a signal: `SIGXCPU'. The value is + measured in seconds. *Note Operation Error Signals::. - `stack_t uc_stack' - Stack used for this context. The value need not be (and - normally is not) the stack pointer. *Note Signal Stack::. +`RLIMIT_FSIZE' + The maximum size of file the process can create. Trying to write a + larger file causes a signal: `SIGXFSZ'. *Note Operation Error + Signals::. - `mcontext_t uc_mcontext' - This element contains the actual state of the process. The - `mcontext_t' type is also defined in this header but the - definition should be treated as opaque. Any use of knowledge - of the type makes applications less portable. +`RLIMIT_DATA' + The maximum size of data memory for the process. If the process + tries to allocate data memory beyond this amount, the allocation + function fails. +`RLIMIT_STACK' + The maximum stack size for the process. If the process tries to + extend its stack past this size, it gets a `SIGSEGV' signal. + *Note Program Error Signals::. - Objects of this type have to be created by the user. The -initialization and modification happens through one of the following -functions: +`RLIMIT_CORE' + The maximum size core file that this process can create. If the + process terminates and would dump a core file larger than this, + then no core file is created. So setting this limit to zero + prevents core files from ever being created. - - Function: int getcontext (ucontext_t *UCP) - The `getcontext' function initializes the variable pointed to by - UCP with the context of the calling thread. The context contains - the content of the registers, the signal mask, and the current - stack. Executing the contents would start at the point where the - `getcontext' call just returned. +`RLIMIT_RSS' + The maximum amount of physical memory that this process should get. + This parameter is a guide for the system's scheduler and memory + allocator; the system may give the process more memory when there + is a surplus. - The function returns `0' if successful. Otherwise it returns `-1' - and sets ERRNO accordingly. +`RLIMIT_MEMLOCK' + The maximum amount of memory that can be locked into physical + memory (so it will never be paged out). - The `getcontext' function is similar to `setjmp' but it does not -provide an indication of whether the function returns for the first -time or whether the initialized context was used and the execution is -resumed at just that point. If this is necessary the user has to take -determine this herself. This must be done carefully since the context -contains registers which might contain register variables. This is a -good situation to define variables with `volatile'. +`RLIMIT_NPROC' + The maximum number of processes that can be created with the same + user ID. If you have reached the limit for your user ID, `fork' + will fail with `EAGAIN'. *Note Creating a Process::. - Once the context variable is initialized it can be used as is or it -can be modified. The latter is normally done to implement co-routines -or similar constructs. The `makecontext' function is what has to be -used to do that. +`RLIMIT_NOFILE' +`RLIMIT_OFILE' + The maximum number of files that the process can open. If it + tries to open more files than this, its open attempt fails with + `errno' `EMFILE'. *Note Error Codes::. Not all systems support + this limit; GNU does, and 4.4 BSD does. - - Function: void makecontext (ucontext_t *UCP, void (*FUNC) (void), - int ARGC, ...) - The UCP parameter passed to the `makecontext' shall be initialized - by a call to `getcontext'. The context will be modified to in a - way so that if the context is resumed it will start by calling the - function `func' which gets ARGC integer arguments passed. The - integer arguments which are to be passed should follow the ARGC - parameter in the call to `makecontext'. +`RLIMIT_AS' + The maximum size of total memory that this process should get. If + the process tries to allocate more memory beyond this amount with, + for example, `brk', `malloc', `mmap' or `sbrk', the allocation + function fails. - Before the call to this function the `uc_stack' and `uc_link' - element of the UCP structure should be initialized. The - `uc_stack' element describes the stack which is used for this - context. No two contexts which are used at the same time should - use the same memory region for a stack. +`RLIM_NLIMITS' + The number of different resource limits. Any valid RESOURCE + operand must be less than `RLIM_NLIMITS'. - The `uc_link' element of the object pointed to by UCP should be a - pointer to the context to be executed when the function FUNC - returns or it should be a null pointer. See `setcontext' for more - information about the exact use. + - Constant: int RLIM_INFINITY + This constant stands for a value of "infinity" when supplied as + the limit value in `setrlimit'. - While allocating the memory for the stack one has to be careful. -Most modern processors keep track of whether a certain memory region is -allowed to contain code which is executed or not. Data segments and -heap memory is normally not tagged to allow this. The result is that -programs would fail. Examples for such code include the calling -sequences the GNU C compiler generates for calls to nested functions. -Safe ways to allocate stacks correctly include using memory on the -original threads stack or explicitly allocate memory tagged for -execution using (*note Memory-mapped I/O::). + The following are historical functions to do some of what the +functions above do. The functions above are better choices. - *Compatibility note*: The current Unix standard is very imprecise -about the way the stack is allocated. All implementations seem to agree -that the `uc_stack' element must be used but the values stored in the -elements of the `stack_t' value are unclear. The GNU C library and -most other Unix implementations require the `ss_sp' value of the -`uc_stack' element to point to the base of the memory region allocated -for the stack and the size of the memory region is stored in `ss_size'. -There are implements out there which require `ss_sp' to be set to the -value the stack pointer will have (which can depending on the direction -the stack grows be different). This difference makes the `makecontext' -function hard to use and it requires detection of the platform at -compile time. + `ulimit' and the command symbols are declared in `ulimit.h'. - - Function: int setcontext (const ucontext_t *UCP) - The `setcontext' function restores the context described by UCP. - The context is not modified and can be reused as often as wanted. + - Function: int ulimit (int CMD, ...) + `ulimit' gets the current limit or sets the current and maximum + limit for a particular resource for the calling process according + to the command CMD.a - If the context was created by `getcontext' execution resumes with - the registers filled with the same values and the same stack as if - the `getcontext' call just returned. + If you are getting a limit, the command argument is the only + argument. If you are setting a limit, there is a second argument: + `long int' LIMIT which is the value to which you are setting the + limit. - If the context was modified with a call to `makecontext' execution - continues with the function passed to `makecontext' which gets the - specified parameters passed. If this function returns execution is - resumed in the context which was referenced by the `uc_link' - element of the context structure passed to `makecontext' at the - time of the call. If `uc_link' was a null pointer the application - terminates in this case. + The CMD values and the operations they specify are: + `GETFSIZE' + Get the current limit on the size of a file, in units of 512 + bytes. - Since the context contains information about the stack no two - threads should use the same context at the same time. The result - in most cases would be disastrous. + `SETFSIZE' + Set the current and maximum limit on the size of a file to + LIMIT * 512 bytes. - The `setcontext' function does not return unless an error occurred - in which case it returns `-1'. + There are also some other CMD values that may do things on some + systems, but they are not supported. - The `setcontext' function simply replaces the current context with -the one described by the UCP parameter. This is often useful but there -are situations where the current context has to be preserved. + Only the superuser may increase a maximum limit. - - Function: int swapcontext (ucontext_t *restrict OUCP, const - ucontext_t *restrict UCP) - The `swapcontext' function is similar to `setcontext' but instead - of just replacing the current context the latter is first saved in - the object pointed to by OUCP as if this was a call to - `getcontext'. The saved context would resume after the call to - `swapcontext'. + When you successfully get a limit, the return value of `ulimit' is + that limit, which is never negative. When you successfully set a + limit, the return value is zero. When the function fails, the + return value is `-1' and `errno' is set according to the reason: - Once the current context is saved the context described in UCP is - installed and execution continues as described in this context. + `EPERM' + A process tried to increase a maximum limit, but is not + superuser. - If `swapcontext' succeeds the function does not return unless the - context OUCP is used without prior modification by `makecontext'. - The return value in this case is `0'. If the function fails it - returns `-1' and set ERRNO accordingly. -Example for SVID Context Handling -================================= + `vlimit' and its resource symbols are declared in `sys/vlimit.h'. - The easiest way to use the context handling functions is as a -replacement for `setjmp' and `longjmp'. The context contains on most -platforms more information which might lead to less surprises but this -also means using these functions is more expensive (beside being less -portable). + - Function: int vlimit (int RESOURCE, int LIMIT) + `vlimit' sets the current limit for a resource for a process. - int - random_search (int n, int (*fp) (int, ucontext_t *)) - { - volatile int cnt = 0; - ucontext_t uc; - - /* Safe current context. */ - if (getcontext (&uc) < 0) - return -1; - - /* If we have not tried N times try again. */ - if (cnt++ < n) - /* Call the function with a new random number - and the context. */ - if (fp (rand (), &uc) != 0) - /* We found what we were looking for. */ - return 1; - - /* Not found. */ - return 0; - } + RESOURCE identifies the resource: - Using contexts in such a way enables emulating exception handling. -The search functions passed in the FP parameter could be very large, -nested, and complex which would make it complicated (or at least would -require a lot of code) to leave the function with an error value which -has to be passed down to the caller. By using the context it is -possible to leave the search function in one step and allow restarting -the search which also has the nice side effect that it can be -significantly faster. + `LIM_CPU' + Maximum CPU time.

The -operating system uses signals to report exceptional situations to an -executing program. Some signals report errors such as references to -invalid memory addresses; others report asynchronous events, such as -disconnection of a phone line. + When multiple processes simultaneously require CPU time, the system's +scheduling policy and process CPU priorities determine which processes +get it. This section describes how that determination is made and GNU +C library functions to control it. - The GNU C library defines a variety of signal types, each for a -particular kind of event. Some kinds of events make it inadvisable or -impossible for the program to proceed as usual, and the corresponding -signals normally abort the program. Other kinds of signals that report -harmless events are ignored by default. + It is common to refer to CPU scheduling simply as scheduling and a +process' CPU priority simply as the process' priority, with the CPU +resource being implied. Bear in mind, though, that CPU time is not the +only resource a process uses or that processes contend for. In some +cases, it is not even particularly important. Giving a process a high +"priority" may have very little effect on how fast a process runs with +respect to other processes. The priorities discussed in this section +apply only to CPU time. - If you anticipate an event that causes signals, you can define a -handler function and tell the operating system to run it when that -particular type of signal arrives. + CPU scheduling is a complex issue and different systems do it in +wildly different ways. New ideas continually develop and find their +way into the intricacies of the various systems' scheduling algorithms. +This section discusses the general concepts, some specifics of systems +that commonly use the GNU C library, and some standards. - Finally, one process can send a signal to another process; this -allows a parent process to abort a child, or two related processes to -communicate and synchronize. + For simplicity, we talk about CPU contention as if there is only one +CPU in the system.

This is true +even if the process with the lower priority is already using the CPU +(i.e. the scheduling is preemptive). Of course, we're only talking +about processes that are running or "ready to run," which means they are +ready to execute instructions right now. When a process blocks to wait +for something like I/O, its absolute priority is irrelevant. - -File: libc.info, Node: Kinds of Signals, Next: Signal Generation, Up: Concepts of Signals + *Note:* The term "runnable" is a synonym for "ready to run." -Some Kinds of Signals ---------------------- + When two processes are running or ready to run and both have the same +absolute priority, it's more interesting. In that case, who gets the +CPU is determined by the scheduling policy. If the processes have +absolute priority 0, the traditional scheduling policy described in +*Note Traditional Scheduling:: applies. Otherwise, the policies +described in *Note Realtime Scheduling:: apply. - A signal reports the occurrence of an exceptional event. These are -some of the events that can cause (or "generate", or "raise") a signal: + You normally give an absolute priority above 0 only to a process that +can be trusted not to hog the CPU. Such processes are designed to block +(or terminate) after relatively short CPU runs. - * A program error such as dividing by zero or issuing an address - outside the valid range. + A process begins life with the same absolute priority as its parent +process. Functions described in *Note Basic Scheduling Functions:: can +change it. - * A user request to interrupt or terminate the program. Most - environments are set up to let a user suspend the program by - typing `C-z', or terminate it with `C-c'. Whatever key sequence - is used, the operating system sends the proper signal to interrupt - the process. + Only a privileged process can change a process' absolute priority to +something other than `0'. Only a privileged process or the target +process' owner can change its absolute priority at all. - * The termination of a child process. + POSIX requires absolute priority values used with the realtime +scheduling policies to be consecutive with a range of at least 32. On +Linux, they are 1 through 99. The functions `sched_get_priority_max' +and `sched_set_priority_min' portably tell you what the range is on a +particular system. - * Expiration of a timer or alarm. +Using Absolute Priority +....................... - * A call to `kill' or `raise' by the same process. + One thing you must keep in mind when designing real time +applications is that having higher absolute priority than any other +process doesn't guarantee the process can run continuously. Two things +that can wreck a good CPU run are interrupts and page faults. - * A call to `kill' from another process. Signals are a limited but - useful form of interprocess communication. + Interrupt handlers live in that limbo between processes. The CPU is +executing instructions, but they aren't part of any process. An +interrupt will stop even the highest priority process. So you must +allow for slight delays and make sure that no device in the system has +an interrupt handler that could cause too long a delay between +instructions for your process. - * An attempt to perform an I/O operation that cannot be done. - Examples are reading from a pipe that has no writer (*note Pipes - and FIFOs::), and reading or writing to a terminal in certain - situations (*note Job Control::). + Similarly, a page fault causes what looks like a straightforward +sequence of instructions to take a long time. The fact that other +processes get to run while the page faults in is of no consequence, +because as soon as the I/O is complete, the high priority process will +kick them out and run again, but the wait for the I/O itself could be a +problem. To neutralize this threat, use `mlock' or `mlockall'. - Each of these kinds of events (excepting explicit calls to `kill' -and `raise') generates its own particular kind of signal. The various -kinds of signals are listed and described in detail in *Note Standard -Signals::. + There are a few ramifications of the absoluteness of this priority +on a single-CPU system that you need to keep in mind when you choose to +set a priority and also when you're working on a program that runs with +high absolute priority. Consider a process that has higher absolute +priority than any other process in the system and due to a bug in its +program, it gets into an infinite loop. It will never cede the CPU. +You can't run a command to kill it because your command would need to +get the CPU in order to run. The errant program is in complete +control. It controls the vertical, it controls the horizontal. + + There are two ways to avoid this: 1) keep a shell running somewhere +with a higher absolute priority. 2) keep a controlling terminal +attached to the high priority process group. All the priority in the +world won't stop an interrupt handler from running and delivering a +signal to the process if you hit Control-C. + + Some systems use absolute priority as a means of allocating a fixed +percentage of CPU time to a process. To do this, a super high priority +privileged process constantly monitors the process' CPU usage and raises +its absolute priority when the process isn't getting its entitled share +and lowers it when the process is exceeding it. + + *Note:* The absolute priority is sometimes called the "static +priority." We don't use that term in this manual because it misses the +most important feature of the absolute priority: its absoluteness.  -File: libc.info, Node: Signal Generation, Next: Delivery of Signal, Prev: Kinds of Signals, Up: Concepts of Signals +File: libc.info, Node: Realtime Scheduling, Next: Basic Scheduling Functions, Prev: Absolute Priority, Up: Priority -Concepts of Signal Generation ------------------------------ +Realtime Scheduling +------------------- - In general, the events that generate signals fall into three major -categories: errors, external events, and explicit requests. + Whenever two processes with the same absolute priority are ready to +run, the kernel has a decision to make, because only one can run at a +time. If the processes have absolute priority 0, the kernel makes this +decision as described in *Note Traditional Scheduling::. Otherwise, +the decision is as described in this section. - An error means that a program has done something invalid and cannot -continue execution. But not all kinds of errors generate signals--in -fact, most do not. For example, opening a nonexistent file is an error, -but it does not raise a signal; instead, `open' returns `-1'. In -general, errors that are necessarily associated with certain library -functions are reported by returning a value that indicates an error. -The errors which raise signals are those which can happen anywhere in -the program, not just in library calls. These include division by zero -and invalid memory addresses. + If two processes are ready to run but have different absolute +priorities, the decision is much simpler, and is described in *Note +Absolute Priority::. - An external event generally has to do with I/O or other processes. -These include the arrival of input, the expiration of a timer, and the -termination of a child process. + Each process has a scheduling policy. For processes with absolute +priority other than zero, there are two available: - An explicit request means the use of a library function such as -`kill' whose purpose is specifically to generate a signal. + 1. First Come First Served - Signals may be generated "synchronously" or "asynchronously". A -synchronous signal pertains to a specific action in the program, and is -delivered (unless blocked) during that action. Most errors generate -signals synchronously, and so do explicit requests by a process to -generate a signal for that same process. On some machines, certain -kinds of hardware errors (usually floating-point exceptions) are not -reported completely synchronously, but may arrive a few instructions -later. + 2. Round Robin - Asynchronous signals are generated by events outside the control of -the process that receives them. These signals arrive at unpredictable -times during execution. External events generate signals -asynchronously, and so do explicit requests that apply to some other -process. + The most sensible case is where all the processes with a certain +absolute priority have the same scheduling policy. We'll discuss that +first. - A given type of signal is either typically synchronous or typically -asynchronous. For example, signals for errors are typically synchronous -because errors generate signals synchronously. But any type of signal -can be generated synchronously or asynchronously with an explicit -request. + In Round Robin, processes share the CPU, each one running for a small +quantum of time ("time slice") and then yielding to another in a +circular fashion. Of course, only processes that are ready to run and +have the same absolute priority are in this circle. + + In First Come First Served, the process that has been waiting the +longest to run gets the CPU, and it keeps it until it voluntarily +relinquishes the CPU, runs out of things to do (blocks), or gets +preempted by a higher priority process. + + First Come First Served, along with maximal absolute priority and +careful control of interrupts and page faults, is the one to use when a +process absolutely, positively has to run at full CPU speed or not at +all. + + Judicious use of `sched_yield' function invocations by processes +with First Come First Served scheduling policy forms a good compromise +between Round Robin and First Come First Served. + + To understand how scheduling works when processes of different +scheduling policies occupy the same absolute priority, you have to know +the nitty gritty details of how processes enter and exit the ready to +run list: + + In both cases, the ready to run list is organized as a true queue, +where a process gets pushed onto the tail when it becomes ready to run +and is popped off the head when the scheduler decides to run it. Note +that ready to run and running are two mutually exclusive states. When +the scheduler runs a process, that process is no longer ready to run +and no longer in the ready to run list. When the process stops +running, it may go back to being ready to run again. + + The only difference between a process that is assigned the Round +Robin scheduling policy and a process that is assigned First Come First +Serve is that in the former case, the process is automatically booted +off the CPU after a certain amount of time. When that happens, the +process goes back to being ready to run, which means it enters the +queue at the tail. The time quantum we're talking about is small. +Really small. This is not your father's timesharing. For example, +with the Linux kernel, the round robin time slice is a thousand times +shorter than its typical time slice for traditional scheduling. + + A process begins life with the same scheduling policy as its parent +process. Functions described in *Note Basic Scheduling Functions:: can +change it. + + Only a privileged process can set the scheduling policy of a process +that has absolute priority higher than 0.  -File: libc.info, Node: Delivery of Signal, Prev: Signal Generation, Up: Concepts of Signals +File: libc.info, Node: Basic Scheduling Functions, Next: Traditional Scheduling, Prev: Realtime Scheduling, Up: Priority -How Signals Are Delivered -------------------------- +Basic Scheduling Functions +-------------------------- - When a signal is generated, it becomes "pending". Normally it -remains pending for just a short period of time and then is "delivered" -to the process that was signaled. However, if that kind of signal is -currently "blocked", it may remain pending indefinitely--until signals -of that kind are "unblocked". Once unblocked, it will be delivered -immediately. *Note Blocking Signals::. + This section describes functions in the GNU C library for setting the +absolute priority and scheduling policy of a process. - When the signal is delivered, whether right away or after a long -delay, the "specified action" for that signal is taken. For certain -signals, such as `SIGKILL' and `SIGSTOP', the action is fixed, but for -most signals, the program has a choice: ignore the signal, specify a -"handler function", or accept the "default action" for that kind of -signal. The program specifies its choice using functions such as -`signal' or `sigaction' (*note Signal Actions::). We sometimes say -that a handler "catches" the signal. While the handler is running, -that particular signal is normally blocked. + *Portability Note:* On systems that have the functions in this +section, the macro _POSIX_PRIORITY_SCHEDULING is defined in +`'. - If the specified action for a kind of signal is to ignore it, then -any such signal which is generated is discarded immediately. This -happens even if the signal is also blocked at the time. A signal -discarded in this way will never be delivered, not even if the program -subsequently specifies a different action for that kind of signal and -then unblocks it. + For the case that the scheduling policy is traditional scheduling, +more functions to fine tune the scheduling are in *Note Traditional +Scheduling::. - If a signal arrives which the program has neither handled nor -ignored, its "default action" takes place. Each kind of signal has its -own default action, documented below (*note Standard Signals::). For -most kinds of signals, the default action is to terminate the process. -For certain kinds of signals that represent "harmless" events, the -default action is to do nothing. + Don't try to make too much out of the naming and structure of these +functions. They don't match the concepts described in this manual +because the functions are as defined by POSIX.1b, but the implementation +on systems that use the GNU C library is the inverse of what the POSIX +structure contemplates. The POSIX scheme assumes that the primary +scheduling parameter is the scheduling policy and that the priority +value, if any, is a parameter of the scheduling policy. In the +implementation, though, the priority value is king and the scheduling +policy, if anything, only fine tunes the effect of that priority. - When a signal terminates a process, its parent process can determine -the cause of termination by examining the termination status code -reported by the `wait' or `waitpid' functions. (This is discussed in -more detail in *Note Process Completion::.) The information it can get -includes the fact that termination was due to a signal and the kind of -signal involved. If a program you run from a shell is terminated by a -signal, the shell typically prints some kind of error message. + The symbols in this section are declared by including file `sched.h'. - The signals that normally represent program errors have a special -property: when one of these signals terminates the process, it also -writes a "core dump file" which records the state of the process at the -time of termination. You can examine the core dump with a debugger to -investigate what caused the error. + - Data Type: struct sched_param + This structure describes an absolute priority. + `int sched_priority' + absolute priority value - If you raise a "program error" signal by explicit request, and this -terminates the process, it makes a core dump file just as if the signal -had been due directly to an error. + - Function: int sched_setscheduler (pid_t PID, int POLICY, const + struct sched_param *PARAM) + This function sets both the absolute priority and the scheduling + policy for a process. - -File: libc.info, Node: Standard Signals, Next: Signal Actions, Prev: Concepts of Signals, Up: Signal Handling + It assigns the absolute priority value given by PARAM and the + scheduling policy POLICY to the process with Process ID PID, or + the calling process if PID is zero.

So this +section describes the only scheduling many programmers need to be +concerned about. + + But just to be clear about the scope of this scheduling: Any time a +process with a absolute priority of 0 and a process with an absolute +priority higher than 0 are ready to run at the same time, the one with +absolute priority 0 does not run. If it's already running when the +higher priority ready-to-run process comes into existence, it stops +immediately. + + In addition to its absolute priority of zero, every process has +another priority, which we will refer to as "dynamic priority" because +it changes over time. The dynamic priority is meaningless for +processes with an absolute priority higher than zero. + + The dynamic priority sometimes determines who gets the next turn on +the CPU. Sometimes it determines how long turns last. Sometimes it +determines whether a process can kick another off the CPU. + + In Linux, the value is a combination of these things, but mostly it +is just determines the length of the time slice. The higher a process' +dynamic priority, the longer a shot it gets on the CPU when it gets one. +If it doesn't use up its time slice before giving up the CPU to do +something like wait for I/O, it is favored for getting the CPU back when +it's ready for it, to finish out its time slice. Other than that, +selection of processes for new time slices is basically round robin. +But the scheduler does throw a bone to the low priority processes: A +process' dynamic priority rises every time it is snubbed in the +scheduling process. In Linux, even the fat kid gets to play. + + The fluctuation of a process' dynamic priority is regulated by +another value: The "nice" value. The nice value is an integer, usually +in the range -20 to 20, and represents an upper limit on a process' +dynamic priority. The higher the nice number, the lower that limit. + + On a typical Linux system, for example, a process with a nice value +of 20 can get only 10 milliseconds on the CPU at a time, whereas a +process with a nice value of -20 can achieve a high enough priority to +get 400 milliseconds. + + The idea of the nice value is deferential courtesy. In the +beginning, in the Unix garden of Eden, all processes shared equally in +the bounty of the computer system. But not all processes really need +the same share of CPU time, so the nice value gave a courteous process +the ability to refuse its equal share of CPU time that others might +prosper. Hence, the higher a process' nice value, the nicer the +process is. (Then a snake came along and offered some process a +negative nice value and the system became the crass resource allocation +system we know today). + + Dynamic priorities tend upward and downward with an objective of +smoothing out allocation of CPU time and giving quick response time to +infrequent requests. But they never exceed their nice limits, so on a +heavily loaded CPU, the nice value effectively determines how fast a +process runs. + + In keeping with the socialistic heritage of Unix process priority, a +process begins life with the same nice value as its parent process and +can raise it at will. A process can also raise the nice value of any +other process owned by the same user (or effective user). But only a +privileged process can lower its nice value. A privileged process can +also raise or lower another process' nice value. + + GNU C Library functions for getting and setting nice values are +described in *Note Traditional Scheduling Functions::. diff -durpN glibc-2.2.4/manual/libc.info-38 glibc-2.2.5/manual/libc.info-38 --- glibc-2.2.4/manual/libc.info-38 Mon Aug 13 15:03:42 2001 +++ glibc-2.2.5/manual/libc.info-38 Sun Jan 20 19:28:42 2002 @@ -1,4 +1,4 @@ -This is libc.info, produced by makeinfo version 4.0c from libc.texinfo. +This is libc.info, produced by makeinfo version 4.0 from libc.texinfo.

The purpose of core dump files is so -that you can examine them with a debugger to investigate what caused -the error. +`PRIO_MIN' + The lowest valid nice value. - - Macro: int SIGFPE - The `SIGFPE' signal reports a fatal arithmetic error. Although the - name is derived from "floating-point exception", this signal - actually covers all arithmetic errors, including division by zero - and overflow. If a program stores integer data in a location - which is then used in a floating-point operation, this often - causes an "invalid operation" exception, because the processor - cannot recognize the data as a floating-point number. +`PRIO_MAX' + The highest valid nice value. - Actual floating-point exceptions are a complicated subject because - there are many types of exceptions with subtly different meanings, - and the `SIGFPE' signal doesn't distinguish between them. The - `IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std - 754-1985 and ANSI/IEEE Std 854-1987)' defines various - floating-point exceptions and requires conforming computer systems - to report their occurrences. However, this standard does not - specify how the exceptions are reported, or what kinds of handling - and control the operating system can offer to the programmer. + - Function: int getpriority (int CLASS, int ID) + Return the nice value of a set of processes; CLASS and ID specify + which ones (see below). If the processes specified do not all + have the same nice value, this returns the lowest value that any + of them has. - BSD systems provide the `SIGFPE' handler with an extra argument that -distinguishes various causes of the exception. In order to access this -argument, you must define the handler to accept two arguments, which -means you must cast it to a one-argument function type in order to -establish the handler. The GNU library does provide this extra -argument, but the value is meaningful only on operating systems that -provide the information (BSD systems and GNU systems). + On success, the return value is `0'. Otherwise, it is `-1' and + `ERRNO' is set accordingly. The `errno' values specific to this + function are: -`FPE_INTOVF_TRAP' - Integer overflow (impossible in a C program unless you enable - overflow trapping in a hardware-specific fashion). + `ESRCH' + The combination of CLASS and ID does not match any existing + process. -`FPE_INTDIV_TRAP' - Integer division by zero. + `EINVAL' + The value of CLASS is not valid. -`FPE_SUBRNG_TRAP' - Subscript-range (something that C programs never check for). + If the return value is `-1', it could indicate failure, or it could + be the nice value. The only way to make certain is to set `errno = + 0' before calling `getpriority', then use `errno != 0' afterward + as the criterion for failure. -`FPE_FLTOVF_TRAP' - Floating overflow trap. + - Function: int setpriority (int CLASS, int ID, int NICEVAL) + Set the nice value of a set of processes to NICEVAL; CLASS and ID + specify which ones (see below). -`FPE_FLTDIV_TRAP' - Floating/decimal division by zero. + The return value is `0' on success, and `-1' on failure. The + following `errno' error condition are possible for this function: -`FPE_FLTUND_TRAP' - Floating underflow trap. (Trapping on floating underflow is not - normally enabled.) + `ESRCH' + The combination of CLASS and ID does not match any existing + process. -`FPE_DECOVF_TRAP' - Decimal overflow trap. (Only a few machines have decimal - arithmetic and C never uses it.) + `EINVAL' + The value of CLASS is not valid. - - Macro: int SIGILL - The name of this signal is derived from "illegal instruction"; it - usually means your program is trying to execute garbage or a - privileged instruction. Since the C compiler generates only valid - instructions, `SIGILL' typically indicates that the executable - file is corrupted, or that you are trying to execute data. Some - common ways of getting into the latter situation are by passing an - invalid object where a pointer to a function was expected, or by - writing past the end of an automatic array (or similar problems - with pointers to automatic variables) and corrupting other data on - the stack such as the return address of a stack frame. + `EPERM' + The call would set the nice value of a process which is owned + by a different user than the calling process (i.e. the target + process' real or effective uid does not match the calling + process' effective uid) and the calling process does not have + `CAP_SYS_NICE' permission. - `SIGILL' can also be generated when the stack overflows, or when - the system has trouble running the handler for a signal. + `EACCES' + The call would lower the process' nice value and the process + does not have `CAP_SYS_NICE' permission. - - Macro: int SIGSEGV - This signal is generated when a program tries to read or write - outside the memory that is allocated for it, or to write memory - that can only be read. (Actually, the signals only occur when the - program goes far enough outside to be detected by the system's - memory protection mechanism.) The name is an abbreviation for - "segmentation violation". - Common ways of getting a `SIGSEGV' condition include dereferencing - a null or uninitialized pointer, or when you use a pointer to step - through an array, but fail to check for the end of the array. It - varies among systems whether dereferencing a null pointer generates - `SIGSEGV' or `SIGBUS'. + The arguments CLASS and ID together specify a set of processes in +which you are interested. These are the possible values of CLASS: - - Macro: int SIGBUS - This signal is generated when an invalid pointer is dereferenced. - Like `SIGSEGV', this signal is typically the result of - dereferencing an uninitialized pointer. The difference between - the two is that `SIGSEGV' indicates an invalid access to valid - memory, while `SIGBUS' indicates an access to an invalid address. - In particular, `SIGBUS' signals often result from dereferencing a - misaligned pointer, such as referring to a four-word integer at an - address not divisible by four. (Each kind of computer has its own - requirements for address alignment.) +`PRIO_PROCESS' + One particular process. The argument ID is a process ID (pid). - The name of this signal is an abbreviation for "bus error". +`PRIO_PGRP' + All the processes in a particular process group. The argument ID + is a process group ID (pgid). - - Macro: int SIGABRT - This signal indicates an error detected by the program itself and - reported by calling `abort'. *Note Aborting a Program::. +`PRIO_USER' + All the processes owned by a particular user (i.e. whose real uid + indicates the user). The argument ID is a user ID (uid). - - Macro: int SIGIOT - Generated by the PDP-11 "iot" instruction. On most machines, this - is just another name for `SIGABRT'. + If the argument ID is 0, it stands for the calling process, its +process group, or its owner (real uid), according to CLASS. - - Macro: int SIGTRAP - Generated by the machine's breakpoint instruction, and possibly - other trap instructions. This signal is used by debuggers. Your - program will probably only see `SIGTRAP' if it is somehow - executing bad instructions. + - Function: int nice (int INCREMENT) + Increment the nice value of the calling process by INCREMENT. The + return value is the new nice value on success, and `-1' on + failure. In the case of failure, `errno' will be set to the same + values as for `setpriority'. - - Macro: int SIGEMT - Emulator trap; this results from certain unimplemented instructions - which might be emulated in software, or the operating system's - failure to properly emulate them. + Here is an equivalent definition of `nice': - - Macro: int SIGSYS - Bad system call; that is to say, the instruction to trap to the - operating system was executed, but the code number for the system - call to perform was invalid. + int + nice (int increment) + { + int result, old = getpriority (PRIO_PROCESS, 0); + result = setpriority (PRIO_PROCESS, 0, old + increment); + if (result != -1) + return old + increment; + else + return -1; + }  -File: libc.info, Node: Termination Signals, Next: Alarm Signals, Prev: Program Error Signals, Up: Standard Signals - -Termination Signals -------------------- - - These signals are all used to tell a process to terminate, in one way -or another. They have different names because they're used for slightly -different purposes, and programs might want to handle them differently. - - The reason for handling these signals is usually so your program can -tidy up as appropriate before actually terminating. For example, you -might want to save state information, delete temporary files, or restore -the previous terminal modes. Such a handler should end by specifying -the default action for the signal that happened and then reraising it; -this will cause the program to terminate with that signal, as if it had -not had a handler. (*Note Termination in Handler::.) - - The (obvious) default action for all of these signals is to cause the -process to terminate. - - - Macro: int SIGTERM - The `SIGTERM' signal is a generic signal used to cause program - termination. Unlike `SIGKILL', this signal can be blocked, - handled, and ignored. It is the normal way to politely ask a - program to terminate. - - The shell command `kill' generates `SIGTERM' by default. - - - Macro: int SIGINT - The `SIGINT' ("program interrupt") signal is sent when the user - types the INTR character (normally `C-c'). *Note Special - Characters::, for information about terminal driver support for - `C-c'. - - - Macro: int SIGQUIT - The `SIGQUIT' signal is similar to `SIGINT', except that it's - controlled by a different key--the QUIT character, usually - `C-\'--and produces a core dump when it terminates the process, - just like a program error signal. You can think of this as a - program error condition "detected" by the user. - - *Note Program Error Signals::, for information about core dumps. - *Note Special Characters::, for information about terminal driver - support. - - Certain kinds of cleanups are best omitted in handling `SIGQUIT'. - For example, if the program creates temporary files, it should - handle the other termination requests by deleting the temporary - files. But it is better for `SIGQUIT' not to delete them, so that - the user can examine them in conjunction with the core dump. - - - Macro: int SIGKILL - The `SIGKILL' signal is used to cause immediate program - termination. It cannot be handled or ignored, and is therefore - always fatal. It is also not possible to block this signal. - - This signal is usually generated only by explicit request. Since - it cannot be handled, you should generate it only as a last - resort, after first trying a less drastic method such as `C-c' or - `SIGTERM'. If a process does not respond to any other termination - signals, sending it a `SIGKILL' signal will almost always cause it - to go away. +File: libc.info, Node: Memory Resources, Next: Processor Resources, Prev: Priority, Up: Resource Usage And Limitation - In fact, if `SIGKILL' fails to terminate a process, that by itself - constitutes an operating system bug which you should report. +Querying memory available resources +=================================== - The system will generate `SIGKILL' for a process itself under some - unusual conditions where the program cannot possibly continue to - run (even to run a signal handler). + The amount of memory available in the system and the way it is +organized determines oftentimes the way programs can and have to work. +For functions like `mmap' it is necessary to know about the size of +individual memory pages and knowing how much memory is available enables +a program to select appropriate sizes for, say, caches. Before we get +into these details a few words about memory subsystems in traditional +Unix systems will be given. - - Macro: int SIGHUP - The `SIGHUP' ("hang-up") signal is used to report that the user's - terminal is disconnected, perhaps because a network or telephone - connection was broken. For more information about this, see *Note - Control Modes::. +* Menu: - This signal is also used to report the termination of the - controlling process on a terminal to jobs associated with that - session; this termination effectively disconnects all processes in - the session from the controlling terminal. For more information, - see *Note Termination Internals::. +* Memory Subsystem:: Overview about traditional Unix memory handling. +* Query Memory Parameters:: How to get information about the memory + subsystem?  -File: libc.info, Node: Alarm Signals, Next: Asynchronous I/O Signals, Prev: Termination Signals, Up: Standard Signals - -Alarm Signals -------------- +File: libc.info, Node: Memory Subsystem, Next: Query Memory Parameters, Up: Memory Resources - These signals are used to indicate the expiration of timers. *Note -Setting an Alarm::, for information about functions that cause these -signals to be sent. +Overview about traditional Unix memory handling +----------------------------------------------- - The default behavior for these signals is to cause program -termination. This default is rarely useful, but no other default would -be useful; most of the ways of using these signals would require -handler functions in any case. + Unix systems normally provide processes virtual address spaces. This +means that the addresses of the memory regions do not have to correspond +directly to the addresses of the actual physical memory which stores the +data. An extra level of indirection is introduced which translates +virtual addresses into physical addresses. This is normally done by the +hardware of the processor. - - Macro: int SIGALRM - This signal typically indicates expiration of a timer that - measures real or clock time. It is used by the `alarm' function, - for example. + Using a virtual address space has several advantage. The most +important is process isolation. The different processes running on the +system cannot interfere directly with each other. No process can write +into the address space of another process (except when shared memory is +used but then it is wanted and controlled). - - Macro: int SIGVTALRM - This signal typically indicates expiration of a timer that - measures CPU time used by the current process. The name is an - abbreviation for "virtual time alarm". + Another advantage of virtual memory is that the address space the +processes see can actually be larger than the physical memory available. +The physical memory can be extended by storage on an external media +where the content of currently unused memory regions is stored. The +address translation can then intercept accesses to these memory regions +and make memory content available again by loading the data back into +memory. This concept makes it necessary that programs which have to use +lots of memory know the difference between available virtual address +space and available physical memory. If the working set of virtual +memory of all the processes is larger than the available physical memory +the system will slow down dramatically due to constant swapping of +memory content from the memory to the storage media and back. This is +called "thrashing". - - Macro: int SIGPROF - This signal typically indicates expiration of a timer that measures - both CPU time used by the current process, and CPU time expended on - behalf of the process by the system. Such a timer is used to - implement code profiling facilities, hence the name of this signal. + A final aspect of virtual memory which is important and follows from +what is said in the last paragraph is the granularity of the virtual +address space handling. When we said that the virtual address handling +stores memory content externally it cannot do this on a byte-by-byte +basis. The administrative overhead does not allow this (leaving alone +the processor hardware). Instead several thousand bytes are handled +together and form a "page". The size of each page is always a power of +two byte. The smallest page size in use today is 4096, with 8192, +16384, and 65536 being other popular sizes.  -File: libc.info, Node: Asynchronous I/O Signals, Next: Job Control Signals, Prev: Alarm Signals, Up: Standard Signals - -Asynchronous I/O Signals ------------------------- - - The signals listed in this section are used in conjunction with -asynchronous I/O facilities. You have to take explicit action by -calling `fcntl' to enable a particular file descriptor to generate -these signals (*note Interrupt Input::). The default action for these -signals is to ignore them. - - - Macro: int SIGIO - This signal is sent when a file descriptor is ready to perform - input or output. +File: libc.info, Node: Query Memory Parameters, Prev: Memory Subsystem, Up: Memory Resources - On most operating systems, terminals and sockets are the only - kinds of files that can generate `SIGIO'; other kinds, including - ordinary files, never generate `SIGIO' even if you ask them to. +How to get information about the memory subsystem? +-------------------------------------------------- - In the GNU system `SIGIO' will always be generated properly if you - successfully set asynchronous mode with `fcntl'. + The page size of the virtual memory the process sees is essential to +know in several situations. Some programming interface (e.g., `mmap', +*note Memory-mapped I/O::) require the user to provide information +adjusted to the page size. In the case of `mmap' is it necessary to +provide a length argument which is a multiple of the page size. +Another place where the knowledge about the page size is useful is in +memory allocation. If one allocates pieces of memory in larger chunks +which are then subdivided by the application code it is useful to +adjust the size of the larger blocks to the page size. If the total +memory requirement for the block is close (but not larger) to a multiple +of the page size the kernel's memory handling can work more effectively +since it only has to allocate memory pages which are fully used. (To do +this optimization it is necessary to know a bit about the memory +allocator which will require a bit of memory itself for each block and +this overhead must not push the total size over the page size multiple. - - Macro: int SIGURG - This signal is sent when "urgent" or out-of-band data arrives on a - socket. *Note Out-of-Band Data::. + The page size traditionally was a compile time constant. But recent +development of processors changed this. Processors now support +different page sizes and they can possibly even vary among different +processes on the same system. Therefore the system should be queried at +runtime about the current page size and no assumptions (except about it +being a power of two) should be made. - - Macro: int SIGPOLL - This is a System V signal name, more or less similar to `SIGIO'. - It is defined only for compatibility. + The correct interface to query about the page size is `sysconf' +(*note Sysconf Definition::) with the parameter `_SC_PAGESIZE'.

If your system -doesn't support job control, then these macros are defined but the -signals themselves can't be raised or handled. + Widely available on System V derived systems is a method to get +information about the physical memory the system has.

If you - establish a handler for this signal while there are child - processes that have terminated but not reported their status via - `wait' or `waitpid' (*note Process Completion::), whether your new - handler applies to those processes or not depends on the - particular operating system. + sysconf (_SC_AVPHYS_PAGES) - - Macro: int SIGCLD - This is an obsolete name for `SIGCHLD'. + These two values help to optimize applications. The value returned +for `_SC_AVPHYS_PAGES' is the amount of memory the application can use +without hindering any other process (given that no other process +increases its memory usage). The value returned for `_SC_PHYS_PAGES' +is more or less a hard limit for the working set. If all applications +together constantly use more than that amount of memory the system is +in trouble. - - Macro: int SIGCONT - You can send a `SIGCONT' signal to a process to make it continue. - This signal is special--it always makes the process continue if it - is stopped, before the signal is delivered. The default behavior - is to do nothing else. You cannot block this signal. You can set - a handler, but `SIGCONT' always makes the process continue - regardless. + The GNU C library provides in addition to these already described +way to get this information two functions. They are declared in the +file `sys/sysinfo.h'. Programmers should prefer to use the `sysconf' +method described above. - Most programs have no reason to handle `SIGCONT'; they simply - resume execution without realizing they were ever stopped. You - can use a handler for `SIGCONT' to make a program do something - special when it is stopped and continued--for example, to reprint - a prompt when it is suspended while waiting for input. + - Function: long int get_phys_pages (void) + The `get_phys_pages' function returns the total number of pages of + physical the system has. To get the amount of memory this number + has to be multiplied by the page size. - - Macro: int SIGSTOP - The `SIGSTOP' signal stops the process.

For more information about how this interacts with - the terminal driver, see *Note Access to the Terminal::. +Learn about the processors available +==================================== - - Macro: int SIGTTOU - This is similar to `SIGTTIN', but is generated when a process in a - background job attempts to write to the terminal or set its modes. - Again, the default action is to stop the process. `SIGTTOU' is - only generated for an attempt to write to the terminal if the - `TOSTOP' output mode is set; *note Output Modes::. + The use of threads or processes with shared memory allows an +application to take advantage of all the processing power a system can +provide.

To determine the number of processors available to the +system one can run - While a process is stopped, no more signals can be delivered to it -until it is continued, except `SIGKILL' signals and (obviously) -`SIGCONT' signals. The signals are marked as pending, but not -delivered until the process is continued. The `SIGKILL' signal always -causes termination of the process and can't be blocked, handled or -ignored. You can ignore `SIGCONT', but it always causes the process to -be continued anyway if it is stopped. Sending a `SIGCONT' signal to a -process causes any pending stop signals for that process to be -discarded. Likewise, any pending `SIGCONT' signals for a process are -discarded when it receives a stop signal. + sysconf (_SC_NPROCESSORS_CONF) - When a process in an orphaned process group (*note Orphaned Process -Groups::) receives a `SIGTSTP', `SIGTTIN', or `SIGTTOU' signal and does -not handle it, the process does not stop.

If you use pipes or FIFOs, you have to design your - application so that one process opens the pipe for reading before - another starts writing.

Otherwise the default is to do nothing. +Introduction to Non-Local Exits +=============================== - -File: libc.info, Node: Signal Messages, Prev: Miscellaneous Signals, Up: Standard Signals + As an example of a situation where a non-local exit can be useful, +suppose you have an interactive program that has a "main loop" that +prompts for and executes commands. Suppose the "read" command reads +input from a file, doing some lexical analysis and parsing of the input +while processing it. If a low-level input error is detected, it would +be useful to be able to return immediately to the "main loop" instead +of having to make each of the lexical analysis, parsing, and processing +phases all have to explicitly deal with error situations initially +detected by nested calls. -Signal Messages ---------------- + (On the other hand, if each of these phases has to do a substantial +amount of cleanup when it exits--such as closing files, deallocating +buffers or other data structures, and the like--then it can be more +appropriate to do a normal return and have each phase do its own +cleanup, because a non-local exit would bypass the intervening phases +and their associated cleanup code entirely. Alternatively, you could +use a non-local exit but do the cleanup explicitly either before or +after returning to the "main loop".) - We mentioned above that the shell prints a message describing the -signal that terminated a child process. The clean way to print a -message describing a signal is to use the functions `strsignal' and -`psignal'. These functions use a signal number to specify which kind -of signal to describe. The signal number may come from the termination -status of a child process (*note Process Completion::) or it may come -from a signal handler in the same process. + In some ways, a non-local exit is similar to using the `return' +statement to return from a function. But while `return' abandons only +a single function call, transferring control back to the point at which +it was called, a non-local exit can potentially abandon many levels of +nested function calls. - - Function: char * strsignal (int SIGNUM) - This function returns a pointer to a statically-allocated string - containing a message describing the signal SIGNUM. You should not - modify the contents of this string; and, since it can be rewritten - on subsequent calls, you should save a copy of it if you need to - reference it later. + You identify return points for non-local exits by calling the +function `setjmp'. This function saves information about the execution +environment in which the call to `setjmp' appears in an object of type +`jmp_buf'. Execution of the program continues normally after the call +to `setjmp', but if an exit is later made to this return point by +calling `longjmp' with the corresponding `jmp_buf' object, control is +transferred back to the point where `setjmp' was called. The return +value from `setjmp' is used to distinguish between an ordinary return +and a return made by a call to `longjmp', so calls to `setjmp' usually +appear in an `if' statement. - This function is a GNU extension, declared in the header file - `string.h'. + Here is how the example program described above might be set up: - - Function: void psignal (int SIGNUM, const char *MESSAGE) - This function prints a message describing the signal SIGNUM to the - standard error output stream `stderr'; see *Note Standard - Streams::. + #include + #include + #include + + jmp_buf main_loop; + + void + abort_to_main_loop (int status) + { + longjmp (main_loop, status); + } + + int + main (void) + { + while (1) + if (setjmp (main_loop)) + puts ("Back at main loop...."); + else + do_command (); + } + + + void + do_command (void) + { + char buffer[128]; + if (fgets (buffer, 128, stdin) == NULL) + abort_to_main_loop (-1); + else + exit (EXIT_SUCCESS); + } - If you call `psignal' with a MESSAGE that is either a null pointer - or an empty string, `psignal' just prints the message - corresponding to SIGNUM, adding a trailing newline. + The function `abort_to_main_loop' causes an immediate transfer of +control back to the main loop of the program, no matter where it is +called from. - If you supply a non-null MESSAGE argument, then `psignal' prefixes - its output with this string. It adds a colon and a space - character to separate the MESSAGE from the string corresponding to - SIGNUM. + The flow of control inside the `main' function may appear a little +mysterious at first, but it is actually a common idiom with `setjmp'. +A normal call to `setjmp' returns zero, so the "else" clause of the +conditional is executed. If `abort_to_main_loop' is called somewhere +within the execution of `do_command', then it actually appears as if +the _same_ call to `setjmp' in `main' were returning a second time with +a value of `-1'. - This function is a BSD feature, declared in the header file - `signal.h'. + So, the general pattern for using `setjmp' looks something like: - There is also an array `sys_siglist' which contains the messages for -the various signal codes. This array exists on BSD systems, unlike -`strsignal'. + if (setjmp (BUFFER)) + /* Code to clean up after premature return. */ + ... + else + /* Code to be executed normally after setting up the return point. */ + ...  -File: libc.info, Node: Signal Actions, Next: Defining Handlers, Prev: Standard Signals, Up: Signal Handling +File: libc.info, Node: Non-Local Details, Next: Non-Local Exits and Signals, Prev: Non-Local Intro, Up: Non-Local Exits -Specifying Signal Actions -========================= +Details of Non-Local Exits +========================== - The simplest way to change the action for a signal is to use the -`signal' function.

Returning from `setjmp' by means of + `longjmp' returns the VALUE argument that was passed to `longjmp', + rather than `0'. (But if VALUE is given as `0', `setjmp' returns + `1'). - -File: libc.info, Node: Basic Signal Handling, Next: Advanced Signal Handling, Up: Signal Actions + There are a lot of obscure but important restrictions on the use of +`setjmp' and `longjmp'. Most of these restrictions are present because +non-local exits require a fair amount of magic on the part of the C +compiler and can interact with other parts of the language in strange +ways. -Basic Signal Handling ---------------------- + The `setjmp' function is actually a macro without an actual function +definition, so you shouldn't try to `#undef' it or take its address. +In addition, calls to `setjmp' are safe in only the following contexts: - The `signal' function provides a simple interface for establishing -an action for a particular signal. The function and associated macros -are declared in the header file `signal.h'. + * As the test expression of a selection or iteration statement (such + as `if', `switch', or `while'). - - Data Type: sighandler_t - This is the type of signal handler functions. Signal handlers - take one integer argument specifying the signal number, and have - return type `void'. So, you should define handler functions like - this: + * As one operand of a equality or comparison operator that appears + as the test expression of a selection or iteration statement. The + other operand must be an integer constant expression. - void HANDLER (int `signum') { ... } + * As the operand of a unary `!' operator, that appears as the test + expression of a selection or iteration statement. - The name `sighandler_t' for this data type is a GNU extension. + * By itself as an expression statement. - - Function: sighandler_t signal (int SIGNUM, sighandler_t ACTION) - The `signal' function establishes ACTION as the action for the - signal SIGNUM. + Return points are valid only during the dynamic extent of the +function that called `setjmp' to establish them. If you `longjmp' to a +return point that was established in a function that has already +returned, unpredictable and disastrous things are likely to happen. - The first argument, SIGNUM, identifies the signal whose behavior - you want to control, and should be a signal number. The proper - way to specify a signal number is with one of the symbolic signal - names (*note Standard Signals::)--don't use an explicit number, - because the numerical code for a given kind of signal may vary - from operating system to operating system. + You should use a nonzero VALUE argument to `longjmp'. While +`longjmp' refuses to pass back a zero argument as the return value from +`setjmp', this is intended as a safety net against accidental misuse +and is not really good programming style. - The second argument, ACTION, specifies the action to use for the - signal SIGNUM. This can be one of the following: + When you perform a non-local exit, accessible objects generally +retain whatever values they had at the time `longjmp' was called. The +exception is that the values of automatic variables local to the +function containing the `setjmp' call that have been changed since the +call to `setjmp' are indeterminate, unless you have declared them +`volatile'. - `SIG_DFL' - `SIG_DFL' specifies the default action for the particular - signal. The default actions for various kinds of signals are - stated in *Note Standard Signals::. + +File: libc.info, Node: Non-Local Exits and Signals, Next: System V contexts, Prev: Non-Local Details, Up: Non-Local Exits - `SIG_IGN' - `SIG_IGN' specifies that the signal should be ignored. +Non-Local Exits and Signals +=========================== - Your program generally should not ignore signals that - represent serious events or that are normally used to request - termination. You cannot ignore the `SIGKILL' or `SIGSTOP' - signals at all. You can ignore program error signals like - `SIGSEGV', but ignoring the error won't enable the program to - continue executing meaningfully. Ignoring user requests such - as `SIGINT', `SIGQUIT', and `SIGTSTP' is unfriendly. + In BSD Unix systems, `setjmp' and `longjmp' also save and restore +the set of blocked signals; see *Note Blocking Signals::. However, the +POSIX.1 standard requires `setjmp' and `longjmp' not to change the set +of blocked signals, and provides an additional pair of functions +(`sigsetjmp' and `siglongjmp') to get the BSD behavior. - When you do not wish signals to be delivered during a certain - part of the program, the thing to do is to block them, not - ignore them. *Note Blocking Signals::. + The behavior of `setjmp' and `longjmp' in the GNU library is +controlled by feature test macros; see *Note Feature Test Macros::. The +default in the GNU system is the POSIX.1 behavior rather than the BSD +behavior. - `HANDLER' - Supply the address of a handler function in your program, to - specify running this handler as the way to deliver the signal. + The facilities in this section are declared in the header file +`setjmp.h'. - For more information about defining signal handler functions, - see *Note Defining Handlers::. + - Data Type: sigjmp_buf + This is similar to `jmp_buf', except that it can also store state + information about the set of blocked signals. - If you set the action for a signal to `SIG_IGN', or if you set it - to `SIG_DFL' and the default action is to ignore that signal, then - any pending signals of that type are discarded (even if they are - blocked). Discarding the pending signals means that they will - never be delivered, not even if you subsequently specify another - action and unblock this kind of signal. + - Function: int sigsetjmp (sigjmp_buf STATE, int SAVESIGS) + This is similar to `setjmp'. If SAVESIGS is nonzero, the set of + blocked signals is saved in STATE and will be restored if a + `siglongjmp' is later performed with this STATE. - The `signal' function returns the action that was previously in - effect for the specified SIGNUM. You can save this value and - restore it later by calling `signal' again. + - Function: void siglongjmp (sigjmp_buf STATE, int VALUE) + This is similar to `longjmp' except for the type of its STATE + argument. If the `sigsetjmp' call that set this STATE used a + nonzero SAVESIGS flag, `siglongjmp' also restores the set of + blocked signals. - If `signal' can't honor the request, it returns `SIG_ERR' instead. - The following `errno' error conditions are defined for this - function: + +File: libc.info, Node: System V contexts, Prev: Non-Local Exits and Signals, Up: Non-Local Exits - `EINVAL' - You specified an invalid SIGNUM; or you tried to ignore or - provide a handler for `SIGKILL' or `SIGSTOP'. +Complete Context Control +======================== - *Compatibility Note:* A problem encountered when working with the -`signal' function is that it has different semantics on BSD and SVID -systems. The difference is that on SVID systems the signal handler is -deinstalled after signal delivery. On BSD systems the handler must be -explicitly deinstalled. In the GNU C Library we use the BSD version by -default. To use the SVID version you can either use the function -`sysv_signal' (see below) or use the `_XOPEN_SOURCE' feature select -macro (*note Feature Test Macros::). In general, use of these -functions should be avoided because of compatibility problems. It is -better to use `sigaction' if it is available since the results are much -more reliable. + The Unix standard one more set of function to control the execution +path and these functions are more powerful than those discussed in this +chapter so far. These function were part of the original System V API +and by this route were added to the Unix API. Beside on branded Unix +implementations these interfaces are not widely available. Not all +platforms and/or architectures the GNU C Library is available on provide +this interface. Use `configure' to detect the availability. - Here is a simple example of setting up a handler to delete temporary -files when certain fatal signals happen: + Similar to the `jmp_buf' and `sigjmp_buf' types used for the +variables to contain the state of the `longjmp' functions the +interfaces of interest here have an appropriate type as well. Objects +of this type are normally much larger since more information is +contained. The type is also used in a few more places as we will see. +The types and functions described in this section are all defined and +declared respectively in the `ucontext.h' header file. - #include - - void - termination_handler (int signum) - { - struct temp_file *p; - - for (p = temp_file_list; p; p = p->next) - unlink (p->name); - } - - int - main (void) - { - ... - if (signal (SIGINT, termination_handler) == SIG_IGN) - signal (SIGINT, SIG_IGN); - if (signal (SIGHUP, termination_handler) == SIG_IGN) - signal (SIGHUP, SIG_IGN); - if (signal (SIGTERM, termination_handler) == SIG_IGN) - signal (SIGTERM, SIG_IGN); - ... - } + - Data Type: ucontext_t + The `ucontext_t' type is defined as a structure with as least the + following elements: -Note that if a given signal was previously set to be ignored, this code -avoids altering that setting. This is because non-job-control shells -often ignore certain signals when starting children, and it is important -for the children to respect this. + `ucontext_t *uc_link' + This is a pointer to the next context structure which is used + if the context described in the current structure returns. - We do not handle `SIGQUIT' or the program error signals in this -example because these are designed to provide information for debugging -(a core dump), and the temporary files may give useful information. + `sigset_t uc_sigmask' + Set of signals which are blocked when this context is used. - - Function: sighandler_t sysv_signal (int SIGNUM, sighandler_t ACTION) - The `sysv_signal' implements the behavior of the standard `signal' - function as found on SVID systems. The difference to BSD systems - is that the handler is deinstalled after a delivery of a signal. + `stack_t uc_stack' + Stack used for this context. The value need not be (and + normally is not) the stack pointer. *Note Signal Stack::. - *Compatibility Note:* As said above for `signal', this function - should be avoided when possible. `sigaction' is the preferred - method. + `mcontext_t uc_mcontext' + This element contains the actual state of the process. The + `mcontext_t' type is also defined in this header but the + definition should be treated as opaque. Any use of knowledge + of the type makes applications less portable. - - Function: sighandler_t ssignal (int SIGNUM, sighandler_t ACTION) - The `ssignal' function does the same thing as `signal'; it is - provided only for compatibility with SVID. - - Macro: sighandler_t SIG_ERR - The value of this macro is used as the return value from `signal' - to indicate an error. + Objects of this type have to be created by the user. The +initialization and modification happens through one of the following +functions: - -File: libc.info, Node: Advanced Signal Handling, Next: Signal and Sigaction, Prev: Basic Signal Handling, Up: Signal Actions + - Function: int getcontext (ucontext_t *UCP) + The `getcontext' function initializes the variable pointed to by + UCP with the context of the calling thread. The context contains + the content of the registers, the signal mask, and the current + stack. Executing the contents would start at the point where the + `getcontext' call just returned. -Advanced Signal Handling ------------------------- + The function returns `0' if successful. Otherwise it returns `-1' + and sets ERRNO accordingly. - The `sigaction' function has the same basic effect as `signal': to -specify how a signal should be handled by the process. However, -`sigaction' offers more control, at the expense of more complexity. In -particular, `sigaction' allows you to specify additional flags to -control when the signal is generated and how the handler is invoked. + The `getcontext' function is similar to `setjmp' but it does not +provide an indication of whether the function returns for the first +time or whether the initialized context was used and the execution is +resumed at just that point. If this is necessary the user has to take +determine this herself. This must be done carefully since the context +contains registers which might contain register variables. This is a +good situation to define variables with `volatile'. - The `sigaction' function is declared in `signal.h'. + Once the context variable is initialized it can be used as is or it +can be modified. The latter is normally done to implement co-routines +or similar constructs. The `makecontext' function is what has to be +used to do that. - - Data Type: struct sigaction - Structures of type `struct sigaction' are used in the `sigaction' - function to specify all the information about how to handle a - particular signal. This structure contains at least the following - members: + - Function: void makecontext (ucontext_t *UCP, void (*FUNC) (void), + int ARGC, ...) + The UCP parameter passed to the `makecontext' shall be initialized + by a call to `getcontext'. The context will be modified to in a + way so that if the context is resumed it will start by calling the + function `func' which gets ARGC integer arguments passed. The + integer arguments which are to be passed should follow the ARGC + parameter in the call to `makecontext'. - `sighandler_t sa_handler' - This is used in the same way as the ACTION argument to the - `signal' function. The value can be `SIG_DFL', `SIG_IGN', or - a function pointer. *Note Basic Signal Handling::. + Before the call to this function the `uc_stack' and `uc_link' + element of the UCP structure should be initialized. The + `uc_stack' element describes the stack which is used for this + context. No two contexts which are used at the same time should + use the same memory region for a stack. - `sigset_t sa_mask' - This specifies a set of signals to be blocked while the - handler runs. Blocking is explained in *Note Blocking for - Handler::. Note that the signal that was delivered is - automatically blocked by default before its handler is - started; this is true regardless of the value in `sa_mask'. - If you want that signal not to be blocked within its handler, - you must write code in the handler to unblock it. + The `uc_link' element of the object pointed to by UCP should be a + pointer to the context to be executed when the function FUNC + returns or it should be a null pointer. See `setcontext' for more + information about the exact use. - `int sa_flags' - This specifies various flags which can affect the behavior of - the signal. These are described in more detail in *Note - Flags for Sigaction::. + While allocating the memory for the stack one has to be careful. +Most modern processors keep track of whether a certain memory region is +allowed to contain code which is executed or not. Data segments and +heap memory is normally not tagged to allow this. The result is that +programs would fail. Examples for such code include the calling +sequences the GNU C compiler generates for calls to nested functions. +Safe ways to allocate stacks correctly include using memory on the +original threads stack or explicitly allocate memory tagged for +execution using (*note Memory-mapped I/O::). - - Function: int sigaction (int SIGNUM, const struct sigaction - *restrict ACTION, struct sigaction *restrict OLD-ACTION) - The ACTION argument is used to set up a new action for the signal - SIGNUM, while the OLD-ACTION argument is used to return - information about the action previously associated with this - symbol. (In other words, OLD-ACTION has the same purpose as the - `signal' function's return value--you can check to see what the - old action in effect for the signal was, and restore it later if - you want.) + *Compatibility note*: The current Unix standard is very imprecise +about the way the stack is allocated. All implementations seem to agree +that the `uc_stack' element must be used but the values stored in the +elements of the `stack_t' value are unclear. The GNU C library and +most other Unix implementations require the `ss_sp' value of the +`uc_stack' element to point to the base of the memory region allocated +for the stack and the size of the memory region is stored in `ss_size'. +There are implements out there which require `ss_sp' to be set to the +value the stack pointer will have (which can depending on the direction +the stack grows be different). This difference makes the `makecontext' +function hard to use and it requires detection of the platform at +compile time. - Either ACTION or OLD-ACTION can be a null pointer. If OLD-ACTION - is a null pointer, this simply suppresses the return of - information about the old action. If ACTION is a null pointer, - the action associated with the signal SIGNUM is unchanged; this - allows you to inquire about how a signal is being handled without - changing that handling. + - Function: int setcontext (const ucontext_t *UCP) + The `setcontext' function restores the context described by UCP. + The context is not modified and can be reused as often as wanted. - The return value from `sigaction' is zero if it succeeds, and `-1' - on failure. The following `errno' error conditions are defined - for this function: + If the context was created by `getcontext' execution resumes with + the registers filled with the same values and the same stack as if + the `getcontext' call just returned. - `EINVAL' - The SIGNUM argument is not valid, or you are trying to trap - or ignore `SIGKILL' or `SIGSTOP'. + If the context was modified with a call to `makecontext' execution + continues with the function passed to `makecontext' which gets the + specified parameters passed. If this function returns execution is + resumed in the context which was referenced by the `uc_link' + element of the context structure passed to `makecontext' at the + time of the call. If `uc_link' was a null pointer the application + terminates in this case. - -File: libc.info, Node: Signal and Sigaction, Next: Sigaction Function Example, Prev: Advanced Signal Handling, Up: Signal Actions + Since the context contains information about the stack no two + threads should use the same context at the same time. The result + in most cases would be disastrous. -Interaction of `signal' and `sigaction' ---------------------------------------- + The `setcontext' function does not return unless an error occurred + in which case it returns `-1'. - It's possible to use both the `signal' and `sigaction' functions -within a single program, but you have to be careful because they can -interact in slightly strange ways. + The `setcontext' function simply replaces the current context with +the one described by the UCP parameter. This is often useful but there +are situations where the current context has to be preserved. - The `sigaction' function specifies more information than the -`signal' function, so the return value from `signal' cannot express the -full range of `sigaction' possibilities. Therefore, if you use -`signal' to save and later reestablish an action, it may not be able to -reestablish properly a handler that was established with `sigaction'. + - Function: int swapcontext (ucontext_t *restrict OUCP, const + ucontext_t *restrict UCP) + The `swapcontext' function is similar to `setcontext' but instead + of just replacing the current context the latter is first saved in + the object pointed to by OUCP as if this was a call to + `getcontext'. The saved context would resume after the call to + `swapcontext'. - To avoid having problems as a result, always use `sigaction' to save -and restore a handler if your program uses `sigaction' at all. Since -`sigaction' is more general, it can properly save and reestablish any -action, regardless of whether it was established originally with -`signal' or `sigaction'. + Once the current context is saved the context described in UCP is + installed and execution continues as described in this context. - On some systems if you establish an action with `signal' and then -examine it with `sigaction', the handler address that you get may not -be the same as what you specified with `signal'. It may not even be -suitable for use as an action argument with `signal'. But you can rely -on using it as an argument to `sigaction'. This problem never happens -on the GNU system. + If `swapcontext' succeeds the function does not return unless the + context OUCP is used without prior modification by `makecontext'. + The return value in this case is `0'. If the function fails it + returns `-1' and set ERRNO accordingly. - So, you're better off using one or the other of the mechanisms -consistently within a single program. +Example for SVID Context Handling +================================= - *Portability Note:* The basic `signal' function is a feature of -ISO C, while `sigaction' is part of the POSIX.1 standard. If you are -concerned about portability to non-POSIX systems, then you should use -the `signal' function instead. + The easiest way to use the context handling functions is as a +replacement for `setjmp' and `longjmp'. The context contains on most +platforms more information which might lead to less surprises but this +also means using these functions is more expensive (beside being less +portable). - -File: libc.info, Node: Sigaction Function Example, Next: Flags for Sigaction, Prev: Signal and Sigaction, Up: Signal Actions + int + random_search (int n, int (*fp) (int, ucontext_t *)) + { + volatile int cnt = 0; + ucontext_t uc; + + /* Safe current context. */ + if (getcontext (&uc) < 0) + return -1; + + /* If we have not tried N times try again. */ + if (cnt++ < n) + /* Call the function with a new random number + and the context. */ + if (fp (rand (), &uc) != 0) + /* We found what we were looking for. */ + return 1; + + /* Not found. */ + return 0; + } -`sigaction' Function Example ----------------------------- + Using contexts in such a way enables emulating exception handling. +The search functions passed in the FP parameter could be very large, +nested, and complex which would make it complicated (or at least would +require a lot of code) to leave the function with an error value which +has to be passed down to the caller. By using the context it is +possible to leave the search function in one step and allow restarting +the search which also has the nice side effect that it can be +significantly faster. - In *Note Basic Signal Handling::, we gave an example of establishing -a simple handler for termination signals using `signal'.

Most of the time, `SA_RESTART' is a good value -to use for this field. + A "signal" is a software interrupt delivered to a process.

Thus, you -should choose the flags you want to set, OR those flags together, and -store the result in the `sa_flags' member of your `sigaction' structure. + The GNU C library defines a variety of signal types, each for a +particular kind of event.

This -section describes what your handler should do, and what you should -avoid. + In general, the events that generate signals fall into three major +categories: errors, external events, and explicit requests. -* Menu: + An error means that a program has done something invalid and cannot +continue execution. But not all kinds of errors generate signals--in +fact, most do not. For example, opening a nonexistent file is an error, +but it does not raise a signal; instead, `open' returns `-1'. In +general, errors that are necessarily associated with certain library +functions are reported by returning a value that indicates an error. +The errors which raise signals are those which can happen anywhere in +the program, not just in library calls. These include division by zero +and invalid memory addresses. -* Handler Returns:: Handlers that return normally, and what - this means. -* Termination in Handler:: How handler functions terminate a program. -* Longjmp in Handler:: Nonlocal transfer of control out of a - signal handler. -* Signals in Handler:: What happens when signals arrive while - the handler is already occupied. -* Merged Signals:: When a second signal arrives before the - first is handled. -* Nonreentrancy:: Do not call any functions unless you know they - are reentrant with respect to signals. -* Atomic Data Access:: A single handler can run in the middle of - reading or writing a single object. + An external event generally has to do with I/O or other processes. +These include the arrival of input, the expiration of a timer, and the +termination of a child process. - -File: libc.info, Node: Handler Returns, Next: Termination in Handler, Up: Defining Handlers + An explicit request means the use of a library function such as +`kill' whose purpose is specifically to generate a signal. -Signal Handlers that Return ---------------------------- + Signals may be generated "synchronously" or "asynchronously". A +synchronous signal pertains to a specific action in the program, and is +delivered (unless blocked) during that action. Most errors generate +signals synchronously, and so do explicit requests by a process to +generate a signal for that same process. On some machines, certain +kinds of hardware errors (usually floating-point exceptions) are not +reported completely synchronously, but may arrive a few instructions +later. - Handlers which return normally are usually used for signals such as -`SIGALRM' and the I/O and interprocess communication signals. But a -handler for `SIGINT' might also return normally after setting a flag -that tells the program to exit at a convenient time. + Asynchronous signals are generated by events outside the control of +the process that receives them. These signals arrive at unpredictable +times during execution. External events generate signals +asynchronously, and so do explicit requests that apply to some other +process. - It is not safe to return normally from the handler for a program -error signal, because the behavior of the program when the handler -function returns is not defined after a program error. *Note Program -Error Signals::. + A given type of signal is either typically synchronous or typically +asynchronous. For example, signals for errors are typically synchronous +because errors generate signals synchronously. But any type of signal +can be generated synchronously or asynchronously with an explicit +request. - Handlers that return normally must modify some global variable in -order to have any effect. Typically, the variable is one that is -examined periodically by the program during normal operation. Its data -type should be `sig_atomic_t' for reasons described in *Note Atomic -Data Access::. + +File: libc.info, Node: Delivery of Signal, Prev: Signal Generation, Up: Concepts of Signals - Here is a simple example of such a program.

Normally it +remains pending for just a short period of time and then is "delivered" +to the process that was signaled. However, if that kind of signal is +currently "blocked", it may remain pending indefinitely--until signals +of that kind are "unblocked". Once unblocked, it will be delivered +immediately. *Note Blocking Signals::. - -File: libc.info, Node: Termination in Handler, Next: Longjmp in Handler, Prev: Handler Returns, Up: Defining Handlers + When the signal is delivered, whether right away or after a long +delay, the "specified action" for that signal is taken. For certain +signals, such as `SIGKILL' and `SIGSTOP', the action is fixed, but for +most signals, the program has a choice: ignore the signal, specify a +"handler function", or accept the "default action" for that kind of +signal. The program specifies its choice using functions such as +`signal' or `sigaction' (*note Signal Actions::). We sometimes say +that a handler "catches" the signal. While the handler is running, +that particular signal is normally blocked. -Handlers That Terminate the Process ------------------------------------ + If the specified action for a kind of signal is to ignore it, then +any such signal which is generated is discarded immediately. This +happens even if the signal is also blocked at the time. A signal +discarded in this way will never be delivered, not even if the program +subsequently specifies a different action for that kind of signal and +then unblocks it. - Handler functions that terminate the program are typically used to -cause orderly cleanup or recovery from program error signals and -interactive interrupts. + If a signal arrives which the program has neither handled nor +ignored, its "default action" takes place. Each kind of signal has its +own default action, documented below (*note Standard Signals::). For +most kinds of signals, the default action is to terminate the process. +For certain kinds of signals that represent "harmless" events, the +default action is to do nothing. - The cleanest way for a handler to terminate the process is to raise -the same signal that ran the handler in the first place. Here is how -to do this: + When a signal terminates a process, its parent process can determine +the cause of termination by examining the termination status code +reported by the `wait' or `waitpid' functions.

(The handler can explicitly -unblock the signal using `sigprocmask', if you want to allow more -signals of this type to arrive; see *Note Process Signal Mask::.) + Some programs handle program error signals in order to tidy up before +terminating; for example, programs that turn off echoing of terminal +input should handle program error signals in order to turn echoing back +on. The handler should end by specifying the default action for the +signal that happened and then reraising it; this will cause the program +to terminate with that signal, as if it had not had a handler. (*Note +Termination in Handler::.) - However, your handler can still be interrupted by delivery of another -kind of signal. To avoid this, you can use the `sa_mask' member of the -action structure passed to `sigaction' to explicitly specify which -signals should be blocked while the signal handler runs. These signals -are in addition to the signal for which the handler was invoked, and -any other signals that are normally blocked by the process. *Note -Blocking for Handler::. + Termination is the sensible ultimate outcome from a program error in +most programs. However, programming systems such as Lisp that can load +compiled user programs might need to keep executing even if a user +program incurs an error. These programs have handlers which use +`longjmp' to return control to the command level. - When the handler returns, the set of blocked signals is restored to -the value it had before the handler ran. So using `sigprocmask' inside -the handler only affects what signals can arrive during the execution of -the handler itself, not what signals can arrive once the handler -returns. + The default action for all of these signals is to cause the process +to terminate. If you block or ignore these signals or establish +handlers for them that return normally, your program will probably +break horribly when such signals happen, unless they are generated by +`raise' or `kill' instead of a real error. - *Portability Note:* Always use `sigaction' to establish a handler -for a signal that you expect to receive asynchronously, if you want -your program to work properly on System V Unix. On this system, the -handling of a signal whose handler was established with `signal' -automatically sets the signal's action back to `SIG_DFL', and the -handler must re-establish itself each time it runs. This practice, -while inconvenient, does work when signals cannot arrive in succession. -However, if another signal can arrive right away, it may arrive before -the handler can re-establish itself. Then the second signal would -receive the default handling, which could terminate the process. + When one of these program error signals terminates a process, it also +writes a "core dump file" which records the state of the process at the +time of termination. The core dump file is named `core' and is written +in whichever directory is current in the process at the time.

The + `IEEE Standard for Binary Floating-Point Arithmetic (ANSI/IEEE Std + 754-1985 and ANSI/IEEE Std 854-1987)' defines various + floating-point exceptions and requires conforming computer systems + to report their occurrences.

In effect, the signals merge into one. This situation can -arise when the signal is blocked, or in a multiprocessing environment -where the system is busy running some other processes while the signals -are delivered. This means, for example, that you cannot reliably use a -signal handler to count signals. The only distinction you can reliably -make is whether at least one signal has arrived since a given time in -the past. + BSD systems provide the `SIGFPE' handler with an extra argument that +distinguishes various causes of the exception.

Once -`p->have_status' is set, it means that the child process is stopped or -terminated, and in either case, it cannot stop or terminate again until -the program has taken notice. *Note Atomic Usage::, for more -information about coping with interruptions during accesses of a -variable. + - Macro: int SIGSEGV + This signal is generated when a program tries to read or write + outside the memory that is allocated for it, or to write memory + that can only be read.

The advantage of this method is that different parts of -the program can check independently, each part checking whether there -has been a signal since that part last checked. + Common ways of getting a `SIGSEGV' condition include dereferencing + a null or uninitialized pointer, or when you use a pointer to step + through an array, but fail to check for the end of the array.

The difference between + the two is that `SIGSEGV' indicates an invalid access to valid + memory, while `SIGBUS' indicates an access to an invalid address. + In particular, `SIGBUS' signals often result from dereferencing a + misaligned pointer, such as referring to a four-word integer at an + address not divisible by four.

The best practice is -to write a handler that does nothing but set an external variable that -the program checks regularly, and leave all serious work to the program. -This is best because the handler can be called asynchronously, at -unpredictable times--perhaps in the middle of a primitive function, or -even between the beginning and the end of a C operator that requires -multiple instructions. The data structures being manipulated might -therefore be in an inconsistent state when the handler function is -invoked. Even copying one `int' variable into another can take two -instructions on most machines. + - Macro: int SIGIOT + Generated by the PDP-11 "iot" instruction.

This signal is used by debuggers. Your + program will probably only see `SIGTRAP' if it is somehow + executing bad instructions. - * If your handler needs to access any global variables from your - program, declare those variables `volatile'. This tells the - compiler that the value of the variable might change - asynchronously, and inhibits certain optimizations that would be - invalidated by such modifications. + - Macro: int SIGEMT + Emulator trap; this results from certain unimplemented instructions + which might be emulated in software, or the operating system's + failure to properly emulate them. - * If you call a function in the handler, make sure it is "reentrant" - with respect to signals, or else make sure that the signal cannot - interrupt a call to a related function. + - Macro: int SIGSYS + Bad system call; that is to say, the instruction to trap to the + operating system was executed, but the code number for the system + call to perform was invalid. - A function can be non-reentrant if it uses memory that is not on the -stack. + +File: libc.info, Node: Termination Signals, Next: Alarm Signals, Prev: Program Error Signals, Up: Standard Signals - * If a function uses a static variable or a global variable, or a - dynamically-allocated object that it finds for itself, then it is - non-reentrant and any two calls to the function can interfere. +Termination Signals +------------------- - For example, suppose that the signal handler uses `gethostbyname'. - This function returns its value in a static object, reusing the - same object each time. If the signal happens to arrive during a - call to `gethostbyname', or even after one (while the program is - still using the value), it will clobber the value that the program - asked for. + These signals are all used to tell a process to terminate, in one way +or another. They have different names because they're used for slightly +different purposes, and programs might want to handle them differently. - However, if the program does not use `gethostbyname' or any other - function that returns information in the same object, or if it - always blocks signals around each use, then you are safe. + The reason for handling these signals is usually so your program can +tidy up as appropriate before actually terminating. For example, you +might want to save state information, delete temporary files, or restore +the previous terminal modes. Such a handler should end by specifying +the default action for the signal that happened and then reraising it; +this will cause the program to terminate with that signal, as if it had +not had a handler. (*Note Termination in Handler::.) - There are a large number of library functions that return values - in a fixed object, always reusing the same object in this fashion, - and all of them cause the same problem. Function descriptions in - this manual always mention this behavior. + The (obvious) default action for all of these signals is to cause the +process to terminate. - * If a function uses and modifies an object that you supply, then it - is potentially non-reentrant; two calls can interfere if they use - the same object. + - Macro: int SIGTERM + The `SIGTERM' signal is a generic signal used to cause program + termination. Unlike `SIGKILL', this signal can be blocked, + handled, and ignored. It is the normal way to politely ask a + program to terminate. - This case arises when you do I/O using streams. Suppose that the - signal handler prints a message with `fprintf'. Suppose that the - program was in the middle of an `fprintf' call using the same - stream when the signal was delivered. Both the signal handler's - message and the program's data could be corrupted, because both - calls operate on the same data structure--the stream itself. + The shell command `kill' generates `SIGTERM' by default. - However, if you know that the stream that the handler uses cannot - possibly be used by the program at a time when signals can arrive, - then you are safe. It is no problem if the program uses some - other stream. + - Macro: int SIGINT + The `SIGINT' ("program interrupt") signal is sent when the user + types the INTR character (normally `C-c'). *Note Special + Characters::, for information about terminal driver support for + `C-c'. - * On most systems, `malloc' and `free' are not reentrant, because - they use a static data structure which records what memory blocks - are free. As a result, no library functions that allocate or free - memory are reentrant. This includes functions that allocate space - to store a result. + - Macro: int SIGQUIT + The `SIGQUIT' signal is similar to `SIGINT', except that it's + controlled by a different key--the QUIT character, usually + `C-\'--and produces a core dump when it terminates the process, + just like a program error signal. You can think of this as a + program error condition "detected" by the user. - The best way to avoid the need to allocate memory in a handler is - to allocate in advance space for signal handlers to use. + *Note Program Error Signals::, for information about core dumps. + *Note Special Characters::, for information about terminal driver + support. - The best way to avoid freeing memory in a handler is to flag or - record the objects to be freed, and have the program check from - time to time whether anything is waiting to be freed. But this - must be done with care, because placing an object on a chain is - not atomic, and if it is interrupted by another signal handler - that does the same thing, you could "lose" one of the objects. + Certain kinds of cleanups are best omitted in handling `SIGQUIT'. + For example, if the program creates temporary files, it should + handle the other termination requests by deleting the temporary + files. But it is better for `SIGQUIT' not to delete them, so that + the user can examine them in conjunction with the core dump. - * Any function that modifies `errno' is non-reentrant, but you can - correct for this: in the handler, save the original value of - `errno' and restore it before returning normally. This prevents - errors that occur within the signal handler from being confused - with errors from system calls at the point the program is - interrupted to run the handler. + - Macro: int SIGKILL + The `SIGKILL' signal is used to cause immediate program + termination. It cannot be handled or ignored, and is therefore + always fatal. It is also not possible to block this signal. - This technique is generally applicable; if you want to call in a - handler a function that modifies a particular object in memory, - you can make this safe by saving and restoring that object. + This signal is usually generated only by explicit request. Since + it cannot be handled, you should generate it only as a last + resort, after first trying a less drastic method such as `C-c' or + `SIGTERM'. If a process does not respond to any other termination + signals, sending it a `SIGKILL' signal will almost always cause it + to go away. - * Merely reading from a memory object is safe provided that you can - deal with any of the values that might appear in the object at a - time when the signal can be delivered. Keep in mind that - assignment to some data types requires more than one instruction, - which means that the handler could run "in the middle of" an - assignment to the variable if its type is not atomic. *Note - Atomic Data Access::. + In fact, if `SIGKILL' fails to terminate a process, that by itself + constitutes an operating system bug which you should report. - * Merely writing into a memory object is safe as long as a sudden - change in the value, at any time when the handler might run, will - not disturb anything. + The system will generate `SIGKILL' for a process itself under some + unusual conditions where the program cannot possibly continue to + run (even to run a signal handler). + + - Macro: int SIGHUP + The `SIGHUP' ("hang-up") signal is used to report that the user's + terminal is disconnected, perhaps because a network or telephone + connection was broken. For more information about this, see *Note + Control Modes::. + + This signal is also used to report the termination of the + controlling process on a terminal to jobs associated with that + session; this termination effectively disconnects all processes in + the session from the controlling terminal.

On most machines, it takes several -instructions to store a new value in `memory', and the value is stored -one word at a time. If the signal is delivered in between these -instructions, the handler might find that `memory.a' is zero and -`memory.b' is one (or vice versa). + In the GNU system `SIGIO' will always be generated properly if you + successfully set asynchronous mode with `fcntl'. - On some machines it may be possible to store a new value in `memory' -with just one instruction that cannot be interrupted.

Reading and writing this data type is guaranteed to -happen in a single instruction, so there's no way for a handler to run -"in the middle" of an access. + These signals are used to support job control. If your system +doesn't support job control, then these macros are defined but the +signals themselves can't be raised or handled. - The type `sig_atomic_t' is always an integer data type, but which -one it is, and how many bits it contains, may vary from machine to -machine. + You should generally leave these signals alone unless you really +understand how job control works. *Note Job Control::. - - Data Type: sig_atomic_t - This is an integer data type.

The default behavior + is to do nothing else. You cannot block this signal. You can set + a handler, but `SIGCONT' always makes the process continue + regardless. + + Most programs have no reason to handle `SIGCONT'; they simply + resume execution without realizing they were ever stopped. You + can use a handler for `SIGCONT' to make a program do something + special when it is stopped and continued--for example, to reprint + a prompt when it is suspended while waiting for input. + + - Macro: int SIGSTOP + The `SIGSTOP' signal stops the process. It cannot be handled, + ignored, or blocked. + + - Macro: int SIGTSTP + The `SIGTSTP' signal is an interactive stop signal.

For more information about terminal driver + support, see *Note Special Characters::. + + - Macro: int SIGTTIN + A process cannot read from the user's terminal while it is running + as a background job. When any process in a background job tries to + read from the terminal, all of the processes in the job are sent a + `SIGTTIN' signal. The default action for this signal is to stop + the process. For more information about how this interacts with + the terminal driver, see *Note Access to the Terminal::. + + - Macro: int SIGTTOU + This is similar to `SIGTTIN', but is generated when a process in a + background job attempts to write to the terminal or set its modes. + Again, the default action is to stop the process. `SIGTTOU' is + only generated for an attempt to write to the terminal if the + `TOSTOP' output mode is set; *note Output Modes::. + + While a process is stopped, no more signals can be delivered to it +until it is continued, except `SIGKILL' signals and (obviously) +`SIGCONT' signals. The signals are marked as pending, but not +delivered until the process is continued. The `SIGKILL' signal always +causes termination of the process and can't be blocked, handled or +ignored. You can ignore `SIGCONT', but it always causes the process to +be continued anyway if it is stopped. Sending a `SIGCONT' signal to a +process causes any pending stop signals for that process to be +discarded. Likewise, any pending `SIGCONT' signals for a process are +discarded when it receives a stop signal. + + When a process in an orphaned process group (*note Orphaned Process +Groups::) receives a `SIGTSTP', `SIGTTIN', or `SIGTTOU' signal and does +not handle it, the process does not stop. Stopping the process would +probably not be very useful, since there is no shell program that will +notice it stop and allow the user to continue it. What happens instead +depends on the operating system you are using. Some systems may do +nothing; others may deliver another signal instead, such as `SIGKILL' +or `SIGHUP'.

For example, a flag which is set by the handler, and -tested and cleared by the main program from time to time, is always safe -even if access actually requires two instructions. To show that this is -so, we must consider each access that could be interrupted, and show -that there is no problem if it is interrupted. + These signals are used to report various errors generated by an +operation done by the program. They do not necessarily indicate a +programming error in the program, but an error that prevents an +operating system call from completing. The default action for all of +them is to cause the process to terminate. - An interrupt in the middle of testing the flag is safe because -either it's recognized to be nonzero, in which case the precise value -doesn't matter, or it will be seen to be nonzero the next time it's -tested. + - Macro: int SIGPIPE + Broken pipe. If you use pipes or FIFOs, you have to design your + application so that one process opens the pipe for reading before + another starts writing. If the reading process never starts, or + terminates unexpectedly, writing to the pipe or FIFO raises a + `SIGPIPE' signal. If `SIGPIPE' is blocked, handled or ignored, + the offending call fails with `EPIPE' instead. - An interrupt in the middle of clearing the flag is no problem because -either the value ends up zero, which is what happens if a signal comes -in just before the flag is cleared, or the value ends up nonzero, and -subsequent events occur as if the signal had come in just after the flag -was cleared. As long as the code handles both of these cases properly, -it can also handle a signal in the middle of clearing the flag. (This -is an example of the sort of reasoning you need to do to figure out -whether non-atomic usage is safe.) + Pipes and FIFO special files are discussed in more detail in *Note + Pipes and FIFOs::. - Sometimes you can insure uninterrupted access to one object by -protecting its use with another object, perhaps one whose type -guarantees atomicity. *Note Merged Signals::, for an example. + Another cause of `SIGPIPE' is when you try to output to a socket + that isn't connected. *Note Sending Data::. + + - Macro: int SIGLOST + Resource lost.

If the signal handler -returns, the system faces the question: what should happen next? + These signals are used for various other purposes. In general, they +will not affect your program unless it explicitly uses them for +something. - POSIX specifies one approach: make the primitive fail right away. -The error code for this kind of failure is `EINTR'. This is flexible, -but usually inconvenient. Typically, POSIX applications that use signal -handlers must check for `EINTR' after each library function that can -return it, in order to try the call again. Often programmers forget to -check, which is a common source of error. + - Macro: int SIGUSR1 + - Macro: int SIGUSR2 + The `SIGUSR1' and `SIGUSR2' signals are set aside for you to use + any way you want.

If -you choose this approach, you need not be concerned with `EINTR'. + If a program does full-screen display, it should handle `SIGWINCH'. + When the signal arrives, it should fetch the new screen size and + reformat its display accordingly. - You can choose either approach with the GNU library. If you use -`sigaction' to establish a signal handler, you can specify how that -handler should behave.

The function and associated macros +are declared in the header file `signal.h'. - - Function: int raise (int SIGNUM) - The `raise' function sends the signal SIGNUM to the calling - process. It returns zero if successful and a nonzero value if it - fails. About the only reason for failure would be if the value of - SIGNUM is invalid. + - Data Type: sighandler_t + This is the type of signal handler functions. Signal handlers + take one integer argument specifying the signal number, and have + return type `void'. So, you should define handler functions like + this: - - Function: int gsignal (int SIGNUM) - The `gsignal' function does the same thing as `raise'; it is - provided only for compatibility with SVID. + void HANDLER (int `signum') { ... } - One convenient use for `raise' is to reproduce the default behavior -of a signal that you have trapped. For instance, suppose a user of your -program types the SUSP character (usually `C-z'; *note Special -Characters::) to send it an interactive stop signal (`SIGTSTP'), and -you want to clean up some internal data buffers before stopping. You -might set this up like this: + The name `sighandler_t' for this data type is a GNU extension. + + - Function: sighandler_t signal (int SIGNUM, sighandler_t ACTION) + The `signal' function establishes ACTION as the action for the + signal SIGNUM. + + The first argument, SIGNUM, identifies the signal whose behavior + you want to control, and should be a signal number. The proper + way to specify a signal number is with one of the symbolic signal + names (*note Standard Signals::)--don't use an explicit number, + because the numerical code for a given kind of signal may vary + from operating system to operating system. + + The second argument, ACTION, specifies the action to use for the + signal SIGNUM. This can be one of the following: + + `SIG_DFL' + `SIG_DFL' specifies the default action for the particular + signal. The default actions for various kinds of signals are + stated in *Note Standard Signals::. + + `SIG_IGN' + `SIG_IGN' specifies that the signal should be ignored. + + Your program generally should not ignore signals that + represent serious events or that are normally used to request + termination. You cannot ignore the `SIGKILL' or `SIGSTOP' + signals at all. You can ignore program error signals like + `SIGSEGV', but ignoring the error won't enable the program to + continue executing meaningfully. Ignoring user requests such + as `SIGINT', `SIGQUIT', and `SIGTSTP' is unfriendly. + + When you do not wish signals to be delivered during a certain + part of the program, the thing to do is to block them, not + ignore them. *Note Blocking Signals::. + + `HANDLER' + Supply the address of a handler function in your program, to + specify running this handler as the way to deliver the signal. + + For more information about defining signal handler functions, + see *Note Defining Handlers::. + + If you set the action for a signal to `SIG_IGN', or if you set it + to `SIG_DFL' and the default action is to ignore that signal, then + any pending signals of that type are discarded (even if they are + blocked). Discarding the pending signals means that they will + never be delivered, not even if you subsequently specify another + action and unblock this kind of signal. + + The `signal' function returns the action that was previously in + effect for the specified SIGNUM. You can save this value and + restore it later by calling `signal' again. + + If `signal' can't honor the request, it returns `SIG_ERR' instead. + The following `errno' error conditions are defined for this + function: + + `EINVAL' + You specified an invalid SIGNUM; or you tried to ignore or + provide a handler for `SIGKILL' or `SIGSTOP'. + + *Compatibility Note:* A problem encountered when working with the +`signal' function is that it has different semantics on BSD and SVID +systems. The difference is that on SVID systems the signal handler is +deinstalled after signal delivery. On BSD systems the handler must be +explicitly deinstalled. In the GNU C Library we use the BSD version by +default. To use the SVID version you can either use the function +`sysv_signal' (see below) or use the `_XOPEN_SOURCE' feature select +macro (*note Feature Test Macros::). In general, use of these +functions should be avoided because of compatibility problems. It is +better to use `sigaction' if it is available since the results are much +more reliable. + + Here is a simple example of setting up a handler to delete temporary +files when certain fatal signals happen: #include - /* When a stop signal arrives, set the action back to the default - and then resend the signal after doing cleanup actions. */ - void - tstp_handler (int sig) + termination_handler (int signum) { - signal (SIGTSTP, SIG_DFL); - /* Do cleanup actions here. */ - ... - raise (SIGTSTP); - } - - /* When the process is continued again, restore the signal handler. */ + struct temp_file *p; - void - cont_handler (int sig) - { - signal (SIGCONT, cont_handler); - signal (SIGTSTP, tstp_handler); + for (p = temp_file_list; p; p = p->next) + unlink (p->name); } - /* Enable both handlers during program initialization. */ - int main (void) { - signal (SIGCONT, cont_handler); - signal (SIGTSTP, tstp_handler); + ... + if (signal (SIGINT, termination_handler) == SIG_IGN) + signal (SIGINT, SIG_IGN); + if (signal (SIGHUP, termination_handler) == SIG_IGN) + signal (SIGHUP, SIG_IGN); + if (signal (SIGTERM, termination_handler) == SIG_IGN) + signal (SIGTERM, SIG_IGN); ... } - *Portability note:* `raise' was invented by the ISO C committee. -Older systems may not support it, so using `kill' may be more portable. -*Note Signaling Another Process::. - - -File: libc.info, Node: Signaling Another Process, Next: Permission for kill, Prev: Signaling Yourself, Up: Generating Signals +Note that if a given signal was previously set to be ignored, this code +avoids altering that setting. This is because non-job-control shells +often ignore certain signals when starting children, and it is important +for the children to respect this. -Signaling Another Process -------------------------- + We do not handle `SIGQUIT' or the program error signals in this +example because these are designed to provide information for debugging +(a core dump), and the temporary files may give useful information. - The `kill' function can be used to send a signal to another process. -In spite of its name, it can be used for a lot of things other than -causing a process to terminate. Some examples of situations where you -might want to send signals between processes are: + - Function: sighandler_t sysv_signal (int SIGNUM, sighandler_t ACTION) + The `sysv_signal' implements the behavior of the standard `signal' + function as found on SVID systems. The difference to BSD systems + is that the handler is deinstalled after a delivery of a signal. - * A parent process starts a child to perform a task--perhaps having - the child running an infinite loop--and then terminates the child - when the task is no longer needed. + *Compatibility Note:* As said above for `signal', this function + should be avoided when possible. `sigaction' is the preferred + method. - * A process executes as part of a group, and needs to terminate or - notify the other processes in the group when an error or other - event occurs. + - Function: sighandler_t ssignal (int SIGNUM, sighandler_t ACTION) + The `ssignal' function does the same thing as `signal'; it is + provided only for compatibility with SVID. - * Two processes need to synchronize while working together. + - Macro: sighandler_t SIG_ERR + The value of this macro is used as the return value from `signal' + to indicate an error. - This section assumes that you know a little bit about how processes -work. For more information on this subject, see *Note Processes::. + +File: libc.info, Node: Advanced Signal Handling, Next: Signal and Sigaction, Prev: Basic Signal Handling, Up: Signal Actions - The `kill' function is declared in `signal.h'. +Advanced Signal Handling +------------------------ - - Function: int kill (pid_t PID, int SIGNUM) - The `kill' function sends the signal SIGNUM to the process or - process group specified by PID. Besides the signals listed in - *Note Standard Signals::, SIGNUM can also have a value of zero to - check the validity of the PID. + The `sigaction' function has the same basic effect as `signal': to +specify how a signal should be handled by the process. However, +`sigaction' offers more control, at the expense of more complexity. In +particular, `sigaction' allows you to specify additional flags to +control when the signal is generated and how the handler is invoked. - The PID specifies the process or process group to receive the - signal: + The `sigaction' function is declared in `signal.h'. - `PID > 0' - The process whose identifier is PID. + - Data Type: struct sigaction + Structures of type `struct sigaction' are used in the `sigaction' + function to specify all the information about how to handle a + particular signal. This structure contains at least the following + members: - `PID == 0' - All processes in the same process group as the sender. + `sighandler_t sa_handler' + This is used in the same way as the ACTION argument to the + `signal' function. The value can be `SIG_DFL', `SIG_IGN', or + a function pointer. *Note Basic Signal Handling::. - `PID < -1' - The process group whose identifier is -PID. + `sigset_t sa_mask' + This specifies a set of signals to be blocked while the + handler runs. Blocking is explained in *Note Blocking for + Handler::. Note that the signal that was delivered is + automatically blocked by default before its handler is + started; this is true regardless of the value in `sa_mask'. + If you want that signal not to be blocked within its handler, + you must write code in the handler to unblock it. - `PID == -1' - If the process is privileged, send the signal to all - processes except for some special system processes. - Otherwise, send the signal to all processes with the same - effective user ID. + `int sa_flags' + This specifies various flags which can affect the behavior of + the signal. These are described in more detail in *Note + Flags for Sigaction::. - A process can send a signal to itself with a call like - `kill (getpid(), SIGNUM)'. If `kill' is used by a process to send - a signal to itself, and the signal is not blocked, then `kill' - delivers at least one signal (which might be some other pending - unblocked signal instead of the signal SIGNUM) to that process - before it returns. + - Function: int sigaction (int SIGNUM, const struct sigaction + *restrict ACTION, struct sigaction *restrict OLD-ACTION) + The ACTION argument is used to set up a new action for the signal + SIGNUM, while the OLD-ACTION argument is used to return + information about the action previously associated with this + symbol. (In other words, OLD-ACTION has the same purpose as the + `signal' function's return value--you can check to see what the + old action in effect for the signal was, and restore it later if + you want.) - The return value from `kill' is zero if the signal can be sent - successfully. Otherwise, no signal is sent, and a value of `-1' is - returned. If PID specifies sending a signal to several processes, - `kill' succeeds if it can send the signal to at least one of them. - There's no way you can tell which of the processes got the signal - or whether all of them did. + Either ACTION or OLD-ACTION can be a null pointer. If OLD-ACTION + is a null pointer, this simply suppresses the return of + information about the old action. If ACTION is a null pointer, + the action associated with the signal SIGNUM is unchanged; this + allows you to inquire about how a signal is being handled without + changing that handling. - The following `errno' error conditions are defined for this - function: + The return value from `sigaction' is zero if it succeeds, and `-1' + on failure. The following `errno' error conditions are defined + for this function: `EINVAL' - The SIGNUM argument is an invalid or unsupported number. - - `EPERM' - You do not have the privilege to send a signal to the process - or any of the processes in the process group named by PID. - - `ESCRH' - The PID argument does not refer to an existing process or - group. + The SIGNUM argument is not valid, or you are trying to trap + or ignore `SIGKILL' or `SIGSTOP'. - - Function: int killpg (int PGID, int SIGNUM) - This is similar to `kill', but sends signal SIGNUM to the process - group PGID. This function is provided for compatibility with BSD; - using `kill' to do this is more portable. + +File: libc.info, Node: Signal and Sigaction, Next: Sigaction Function Example, Prev: Advanced Signal Handling, Up: Signal Actions - As a simple example of `kill', the call `kill (getpid (), SIG)' has -the same effect as `raise (SIG)'. +Interaction of `signal' and `sigaction' +--------------------------------------- - -File: libc.info, Node: Permission for kill, Next: Kill Example, Prev: Signaling Another Process, Up: Generating Signals + It's possible to use both the `signal' and `sigaction' functions +within a single program, but you have to be careful because they can +interact in slightly strange ways. -Permission for using `kill' ---------------------------- + The `sigaction' function specifies more information than the +`signal' function, so the return value from `signal' cannot express the +full range of `sigaction' possibilities. Therefore, if you use +`signal' to save and later reestablish an action, it may not be able to +reestablish properly a handler that was established with `sigaction'. - There are restrictions that prevent you from using `kill' to send -signals to any random process. These are intended to prevent antisocial -behavior such as arbitrarily killing off processes belonging to another -user. In typical use, `kill' is used to pass signals between parent, -child, and sibling processes, and in these situations you normally do -have permission to send signals. The only common exception is when you -run a setuid program in a child process; if the program changes its -real UID as well as its effective UID, you may not have permission to -send a signal. The `su' program does this. + To avoid having problems as a result, always use `sigaction' to save +and restore a handler if your program uses `sigaction' at all. Since +`sigaction' is more general, it can properly save and reestablish any +action, regardless of whether it was established originally with +`signal' or `sigaction'. - Whether a process has permission to send a signal to another process -is determined by the user IDs of the two processes. This concept is -discussed in detail in *Note Process Persona::. + On some systems if you establish an action with `signal' and then +examine it with `sigaction', the handler address that you get may not +be the same as what you specified with `signal'. It may not even be +suitable for use as an action argument with `signal'. But you can rely +on using it as an argument to `sigaction'. This problem never happens +on the GNU system. - Generally, for a process to be able to send a signal to another -process, either the sending process must belong to a privileged user -(like `root'), or the real or effective user ID of the sending process -must match the real or effective user ID of the receiving process. If -the receiving process has changed its effective user ID from the -set-user-ID mode bit on its process image file, then the owner of the -process image file is used in place of its current effective user ID. -In some implementations, a parent process might be able to send signals -to a child process even if the user ID's don't match, and other -implementations might enforce other restrictions. + So, you're better off using one or the other of the mechanisms +consistently within a single program. - The `SIGCONT' signal is a special case. It can be sent if the -sender is part of the same session as the receiver, regardless of user -IDs. + *Portability Note:* The basic `signal' function is a feature of +ISO C, while `sigaction' is part of the POSIX.1 standard. If you are +concerned about portability to non-POSIX systems, then you should use +the `signal' function instead.  -File: libc.info, Node: Kill Example, Prev: Permission for kill, Up: Generating Signals - -Using `kill' for Communication ------------------------------- +File: libc.info, Node: Sigaction Function Example, Next: Flags for Sigaction, Prev: Signal and Sigaction, Up: Signal Actions - Here is a longer example showing how signals can be used for -interprocess communication. This is what the `SIGUSR1' and `SIGUSR2' -signals are provided for. Since these signals are fatal by default, -the process that is supposed to receive them must trap them through -`signal' or `sigaction'. +`sigaction' Function Example +---------------------------- - In this example, a parent process forks a child process and then -waits for the child to complete its initialization. The child process -tells the parent when it is ready by sending it a `SIGUSR1' signal, -using the `kill' function. + In *Note Basic Signal Handling::, we gave an example of establishing +a simple handler for termination signals using `signal'. Here is an +equivalent example using `sigaction': #include - #include - #include - #include - - /* When a `SIGUSR1' signal arrives, set this variable. */ - volatile sig_atomic_t usr_interrupt = 0; void - synch_signal (int sig) - { - usr_interrupt = 1; - } - - /* The child process executes this function. */ - void - child_function (void) + termination_handler (int signum) { - /* Perform initialization. */ - printf ("I'm here!!! My pid is %d.\n", (int) getpid ()); - - /* Let parent know you're done. */ - kill (getppid (), SIGUSR1); + struct temp_file *p; - /* Continue with execution. */ - puts ("Bye, now...."); - exit (0); + for (p = temp_file_list; p; p = p->next) + unlink (p->name); } int main (void) { - struct sigaction usr_action; - sigset_t block_mask; - pid_t child_id; - - /* Establish the signal handler. */ - sigfillset (&block_mask); - usr_action.sa_handler = synch_signal; - usr_action.sa_mask = block_mask; - usr_action.sa_flags = 0; - sigaction (SIGUSR1, &usr_action, NULL); - - /* Create the child process. */ - child_id = fork (); - if (child_id == 0) - child_function (); /* Does not return. */ - - /* Busy wait for the child to send a signal. */ - while (!usr_interrupt) - ; + ... + struct sigaction new_action, old_action; - /* Now continue execution. */ - puts ("That's all, folks!"); + /* Set up the structure to specify the new action. */ + new_action.sa_handler = termination_handler; + sigemptyset (&new_action.sa_mask); + new_action.sa_flags = 0; - return 0; + sigaction (SIGINT, NULL, &old_action); + if (old_action.sa_handler != SIG_IGN) + sigaction (SIGINT, &new_action, NULL); + sigaction (SIGHUP, NULL, &old_action); + if (old_action.sa_handler != SIG_IGN) + sigaction (SIGHUP, &new_action, NULL); + sigaction (SIGTERM, NULL, &old_action); + if (old_action.sa_handler != SIG_IGN) + sigaction (SIGTERM, &new_action, NULL); + ... } - This example uses a busy wait, which is bad, because it wastes CPU -cycles that other programs could otherwise use. It is better to ask the -system to wait until the signal arrives. See the example in *Note -Waiting for a Signal::. - - -File: libc.info, Node: Blocking Signals, Next: Waiting for a Signal, Prev: Generating Signals, Up: Signal Handling - -Blocking Signals -================ - - Blocking a signal means telling the operating system to hold it and -deliver it later. Generally, a program does not block signals -indefinitely--it might as well ignore them by setting their actions to -`SIG_IGN'. But it is useful to block signals briefly, to prevent them -from interrupting sensitive operations. For instance: - - * You can use the `sigprocmask' function to block signals while you - modify global variables that are also modified by the handlers for - these signals. - - * You can set `sa_mask' in your `sigaction' call to block certain - signals while a particular signal handler runs. This way, the - signal handler can run without being interrupted itself by signals. - -* Menu: - -* Why Block:: The purpose of blocking signals. -* Signal Sets:: How to specify which signals to - block. -* Process Signal Mask:: Blocking delivery of signals to your - process during normal execution. -* Testing for Delivery:: Blocking to Test for Delivery of - a Signal. -* Blocking for Handler:: Blocking additional signals while a - handler is being run. -* Checking for Pending Signals:: Checking for Pending Signals -* Remembering a Signal:: How you can get almost the same - effect as blocking a signal, by - handling it and setting a flag - to be tested later. - - -File: libc.info, Node: Why Block, Next: Signal Sets, Up: Blocking Signals - -Why Blocking Signals is Useful ------------------------------- - - Temporary blocking of signals with `sigprocmask' gives you a way to -prevent interrupts during critical parts of your code. If signals -arrive in that part of the program, they are delivered later, after you -unblock them. - - One example where this is useful is for sharing data between a signal -handler and the rest of the program. If the type of the data is not -`sig_atomic_t' (*note Atomic Data Access::), then the signal handler -could run when the rest of the program has only half finished reading -or writing the data. This would lead to confusing consequences. + The program just loads the `new_action' structure with the desired +parameters and passes it in the `sigaction' call. The usage of +`sigemptyset' is described later; see *Note Blocking Signals::. - To make the program reliable, you can prevent the signal handler from -running while the rest of the program is examining or modifying that -data--by blocking the appropriate signal around the parts of the -program that touch the data. + As in the example using `signal', we avoid handling signals +previously set to be ignored. Here we can avoid altering the signal +handler even momentarily, by using the feature of `sigaction' that lets +us examine the current action without specifying a new one. - Blocking signals is also necessary when you want to perform a certain -action only if a signal has not arrived. Suppose that the handler for -the signal sets a flag of type `sig_atomic_t'; you would like to test -the flag and perform the action if the flag is not set. This is -unreliable. Suppose the signal is delivered immediately after you test -the flag, but before the consequent action: then the program will -perform the action even though the signal has arrived. + Here is another example. It retrieves information about the current +action for `SIGINT' without changing that action. - The only way to test reliably for whether a signal has yet arrived -is to test while the signal is blocked. + struct sigaction query_action; + + if (sigaction (SIGINT, NULL, &query_action) < 0) + /* `sigaction' returns -1 in case of error. */ + else if (query_action.sa_handler == SIG_DFL) + /* `SIGINT' is handled in the default, fatal manner. */ + else if (query_action.sa_handler == SIG_IGN) + /* `SIGINT' is ignored. */ + else + /* A programmer-defined signal handler is in effect. */  -File: libc.info, Node: Signal Sets, Next: Process Signal Mask, Prev: Why Block, Up: Blocking Signals +File: libc.info, Node: Flags for Sigaction, Next: Initial Signal Actions, Prev: Sigaction Function Example, Up: Signal Actions -Signal Sets ------------ +Flags for `sigaction' +--------------------- - All of the signal blocking functions use a data structure called a -"signal set" to specify what signals are affected. Thus, every -activity involves two stages: creating the signal set, and then passing -it as an argument to a library function. + The `sa_flags' member of the `sigaction' structure is a catch-all +for special features. Most of the time, `SA_RESTART' is a good value +to use for this field. - These facilities are declared in the header file `signal.h'. + The value of `sa_flags' is interpreted as a bit mask. Thus, you +should choose the flags you want to set, OR those flags together, and +store the result in the `sa_flags' member of your `sigaction' structure. - - Data Type: sigset_t - The `sigset_t' data type is used to represent a signal set. - Internally, it may be implemented as either an integer or structure - type. + Each signal number has its own set of flags. Each call to +`sigaction' affects one particular signal number, and the flags that +you specify apply only to that particular signal. - For portability, use only the functions described in this section - to initialize, change, and retrieve information from `sigset_t' - objects--don't try to manipulate them directly. + In the GNU C library, establishing a handler with `signal' sets all +the flags to zero except for `SA_RESTART', whose value depends on the +settings you have made with `siginterrupt'. *Note Interrupted +Primitives::, to see what this is about. - There are two ways to initialize a signal set. You can initially -specify it to be empty with `sigemptyset' and then add specified -signals individually. Or you can specify it to be full with -`sigfillset' and then delete specified signals individually. + These macros are defined in the header file `signal.h'. - You must always initialize the signal set with one of these two -functions before using it in any other way. Don't try to set all the -signals explicitly because the `sigset_t' object might include some -other information (like a version field) that needs to be initialized as -well. (In addition, it's not wise to put into your program an -assumption that the system has no signals aside from the ones you know -about.) + - Macro: int SA_NOCLDSTOP + This flag is meaningful only for the `SIGCHLD' signal. When the + flag is set, the system delivers the signal for a terminated child + process but not for one that is stopped. By default, `SIGCHLD' is + delivered for both terminated children and stopped children. - - Function: int sigemptyset (sigset_t *SET) - This function initializes the signal set SET to exclude all of the - defined signals. It always returns `0'. + Setting this flag for a signal other than `SIGCHLD' has no effect. - - Function: int sigfillset (sigset_t *SET) - This function initializes the signal set SET to include all of the - defined signals. Again, the return value is `0'. + - Macro: int SA_ONSTACK + If this flag is set for a particular signal number, the system + uses the signal stack when delivering that kind of signal. *Note + Signal Stack::. If a signal with this flag arrives and you have + not set a signal stack, the system terminates the program with + `SIGILL'. - - Function: int sigaddset (sigset_t *SET, int SIGNUM) - This function adds the signal SIGNUM to the signal set SET. All - `sigaddset' does is modify SET; it does not block or unblock any - signals. + - Macro: int SA_RESTART + This flag controls what happens when a signal is delivered during + certain primitives (such as `open', `read' or `write'), and the + signal handler returns normally. There are two alternatives: the + library function can resume, or it can return failure with error + code `EINTR'. - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is defined for this function: + The choice is controlled by the `SA_RESTART' flag for the + particular kind of signal that was delivered. If the flag is set, + returning from a handler resumes the library function. If the + flag is clear, returning from a handler makes the function fail. + *Note Interrupted Primitives::. - `EINVAL' - The SIGNUM argument doesn't specify a valid signal. + +File: libc.info, Node: Initial Signal Actions, Prev: Flags for Sigaction, Up: Signal Actions - - Function: int sigdelset (sigset_t *SET, int SIGNUM) - This function removes the signal SIGNUM from the signal set SET. - All `sigdelset' does is modify SET; it does not block or unblock - any signals. The return value and error conditions are the same - as for `sigaddset'. +Initial Signal Actions +---------------------- - Finally, there is a function to test what signals are in a signal -set: + When a new process is created (*note Creating a Process::), it +inherits handling of signals from its parent process. However, when +you load a new process image using the `exec' function (*note Executing +a File::), any signals that you've defined your own handlers for revert +to their `SIG_DFL' handling. (If you think about it a little, this +makes sense; the handler functions from the old program are specific to +that program, and aren't even present in the address space of the new +program image.) Of course, the new program can establish its own +handlers. - - Function: int sigismember (const sigset_t *SET, int SIGNUM) - The `sigismember' function tests whether the signal SIGNUM is a - member of the signal set SET. It returns `1' if the signal is in - the set, `0' if not, and `-1' if there is an error. + When a program is run by a shell, the shell normally sets the initial +actions for the child process to `SIG_DFL' or `SIG_IGN', as +appropriate. It's a good idea to check to make sure that the shell has +not set up an initial action of `SIG_IGN' before you establish your own +signal handlers. - The following `errno' error condition is defined for this function: + Here is an example of how to establish a handler for `SIGHUP', but +not if `SIGHUP' is currently ignored: - `EINVAL' - The SIGNUM argument doesn't specify a valid signal. + ... + struct sigaction temp; + + sigaction (SIGHUP, NULL, &temp); + + if (temp.sa_handler != SIG_IGN) + { + temp.sa_handler = handle_sighup; + sigemptyset (&temp.sa_mask); + sigaction (SIGHUP, &temp, NULL); + }  -File: libc.info, Node: Process Signal Mask, Next: Testing for Delivery, Prev: Signal Sets, Up: Blocking Signals - -Process Signal Mask -------------------- +File: libc.info, Node: Defining Handlers, Next: Interrupted Primitives, Prev: Signal Actions, Up: Signal Handling - The collection of signals that are currently blocked is called the -"signal mask". Each process has its own signal mask. When you create -a new process (*note Creating a Process::), it inherits its parent's -mask. You can block or unblock signals with total flexibility by -modifying the signal mask. +Defining Signal Handlers +======================== - The prototype for the `sigprocmask' function is in `signal.h'. + This section describes how to write a signal handler function that +can be established with the `signal' or `sigaction' functions. - - Function: int sigprocmask (int HOW, const sigset_t *restrict SET, - sigset_t *restrict OLDSET) - The `sigprocmask' function is used to examine or change the calling - process's signal mask. The HOW argument determines how the signal - mask is changed, and must be one of the following values: + A signal handler is just a function that you compile together with +the rest of the program. Instead of directly invoking the function, +you use `signal' or `sigaction' to tell the operating system to call it +when a signal arrives.

If you block signals explicitly in the -handler, you can't avoid at least a short interval at the beginning of -the handler where they are not yet blocked. - - You cannot remove signals from the process's current mask using this -mechanism.

To avoid this, you can use the `sa_mask' member of the +action structure passed to `sigaction' to explicitly specify which +signals should be blocked while the signal handler runs. These signals +are in addition to the signal for which the handler was invoked, and +any other signals that are normally blocked by the process. *Note +Blocking for Handler::. -* Menu: + When the handler returns, the set of blocked signals is restored to +the value it had before the handler ran.

In effect, the signals merge into one. This situation can +arise when the signal is blocked, or in a multiprocessing environment +where the system is busy running some other processes while the signals +are delivered. This means, for example, that you cannot reliably use a +signal handler to count signals. The only distinction you can reliably +make is whether at least one signal has arrived since a given time in +the past. - If the signal causes a handler function to be executed, then - `pause' returns. This is considered an unsuccessful return (since - "successful" behavior would be to suspend the program forever), so - the return value is `-1'. Even if you specify that other - primitives should resume when a system handler returns (*note - Interrupted Primitives::), this has no effect on `pause'; it - always fails when a signal is handled. + Here is an example of a handler for `SIGCHLD' that compensates for +the fact that the number of signals received may not equal the number of +child processes that generate them. It assumes that the program keeps +track of all the child processes with a chain of structures as follows: - The following `errno' error conditions are defined for this - function: + struct process + { + struct process *next; + /* The process ID of this child. */ + int pid; + /* The descriptor of the pipe or pseudo terminal + on which output comes from this child. */ + int input_descriptor; + /* Nonzero if this process has stopped or terminated. */ + sig_atomic_t have_status; + /* The status of this child; 0 if running, + otherwise a status value from `waitpid'. */ + int status; + }; + + struct process *process_list; - `EINTR' - The function was interrupted by delivery of a signal. + This example also uses a flag to indicate whether signals have +arrived since some time in the past--whenever the program last cleared +it to zero. - If the signal causes program termination, `pause' doesn't return - (obviously). + /* Nonzero means some child's status has changed + so look at `process_list' for the details. */ + int process_status_change; - This function is a cancellation point in multithreaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `pause' is called.

You could, of course, avoid this problem by blocking the signal +while scanning the list, but it is much more elegant to guarantee +correctness by doing things in the right order. - It is safe to use `pause' if the real work of your program is done -by the signal handlers themselves, and the "main program" does nothing -but call `pause'. Each time a signal is delivered, the handler will do -the next batch of work that is to be done, and then return, so that the -main loop of the program can call `pause' again. + The loop which checks process status avoids examining `p->status' +until it sees that status has been validly stored.

This tells the + compiler that the value of the variable might change + asynchronously, and inhibits certain optimizations that would be + invalidated by such modifications. - One other point: you may be wondering why the `while' loop is -necessary at all, since the program is apparently only waiting for one -`SIGUSR1' signal. The answer is that the mask passed to `sigsuspend' -permits the process to be woken up by the delivery of other kinds of -signals, as well--for example, job control signals. If the process is -woken up by a signal that doesn't set `usr_interrupt', it just suspends -itself again until the "right" kind of signal eventually arrives. + * If you call a function in the handler, make sure it is "reentrant" + with respect to signals, or else make sure that the signal cannot + interrupt a call to a related function. - This technique takes a few more lines of preparation, but that is -needed just once for each kind of wait criterion you want to use.

Switching from one stack to the other happens -automatically. (Some non-GNU debuggers on some machines may get -confused if you examine a stack trace while a handler that uses the -signal stack is running.) + There are a large number of library functions that return values + in a fixed object, always reusing the same object in this fashion, + and all of them cause the same problem. Function descriptions in + this manual always mention this behavior. - There are two interfaces for telling the system to use a separate -signal stack. `sigstack' is the older interface, which comes from 4.2 -BSD. `sigaltstack' is the newer interface, and comes from 4.4 BSD. -The `sigaltstack' interface has the advantage that it does not require -your program to know which direction the stack grows, which depends on -the specific machine and operating system. + * If a function uses and modifies an object that you supply, then it + is potentially non-reentrant; two calls can interfere if they use + the same object. - - Data Type: stack_t - This structure describes a signal stack.

Suppose that the + program was in the middle of an `fprintf' call using the same + stream when the signal was delivered.

It is no problem if the program uses some + other stream. - `size_t ss_size' - This is the size (in bytes) of the signal stack which `ss_sp' - points to. You should set this to however much space you - allocated for the stack. + * On most systems, `malloc' and `free' are not reentrant, because + they use a static data structure which records what memory blocks + are free. As a result, no library functions that allocate or free + memory are reentrant. This includes functions that allocate space + to store a result. - There are two macros defined in `signal.h' that you should - use in calculating this size: + The best way to avoid the need to allocate memory in a handler is + to allocate in advance space for signal handlers to use. - `SIGSTKSZ' - This is the canonical size for a signal stack.

The - size of a signal stack *must* be greater than this. + * Any function that modifies `errno' is non-reentrant, but you can + correct for this: in the handler, save the original value of + `errno' and restore it before returning normally. This prevents + errors that occur within the signal handler from being confused + with errors from system calls at the point the program is + interrupted to run the handler. - For most cases, just using `SIGSTKSZ' for `ss_size' is - sufficient. But if you know how much stack space your - program's signal handlers will need, you may want to use - a different size. In this case, you should allocate - `MINSIGSTKSZ' additional bytes for the signal stack and - increase `ss_size' accordingly. + This technique is generally applicable; if you want to call in a + handler a function that modifies a particular object in memory, + you can make this safe by saving and restoring that object. - `int ss_flags' - This field contains the bitwise OR of these flags: + * Merely reading from a memory object is safe provided that you can + deal with any of the values that might appear in the object at a + time when the signal can be delivered.

It contains the following members: + Certain patterns of access avoid any problem even if an access is +interrupted. For example, a flag which is set by the handler, and +tested and cleared by the main program from time to time, is always safe +even if access actually requires two instructions. To show that this is +so, we must consider each access that could be interrupted, and show +that there is no problem if it is interrupted. - `sighandler_t sv_handler' - This is the handler function. + An interrupt in the middle of testing the flag is safe because +either it's recognized to be nonzero, in which case the precise value +doesn't matter, or it will be seen to be nonzero the next time it's +tested. - `int sv_mask' - This is the mask of additional signals to be blocked while - the handler function is being called. + An interrupt in the middle of clearing the flag is no problem because +either the value ends up zero, which is what happens if a signal comes +in just before the flag is cleared, or the value ends up nonzero, and +subsequent events occur as if the signal had come in just after the flag +was cleared. As long as the code handles both of these cases properly, +it can also handle a signal in the middle of clearing the flag. (This +is an example of the sort of reasoning you need to do to figure out +whether non-atomic usage is safe.) - `int sv_flags' - This is a bit mask used to specify various flags which affect - the behavior of the signal. You can also refer to this field - as `sv_onstack'. + Sometimes you can insure uninterrupted access to one object by +protecting its use with another object, perhaps one whose type +guarantees atomicity. *Note Merged Signals::, for an example. - These symbolic constants can be used to provide values for the -`sv_flags' field of a `sigvec' structure.

This is flexible, +but usually inconvenient. Typically, POSIX applications that use signal +handlers must check for `EINTR' after each library function that can +return it, in order to try the call again.

If FAILFLAG - is false, signal SIGNUM restarts primitives. If FAILFLAG is true, - handling SIGNUM causes these primitives to fail with error code - `EINTR'. *Note Interrupted Primitives::. + - Macro: TEMP_FAILURE_RETRY (EXPRESSION) + This macro evaluates EXPRESSION once.

If +you choose this approach, you need not be concerned with `EINTR'. - - Macro: int sigmask (int SIGNUM) - This macro returns a signal mask that has the bit for signal SIGNUM - set. You can bitwise-OR the results of several calls to `sigmask' - together to specify more than one signal. For example, + You can choose either approach with the GNU library. If you use +`sigaction' to establish a signal handler, you can specify how that +handler should behave. If you specify the `SA_RESTART' flag, return +from that handler will resume a primitive; otherwise, return from that +handler will cause `EINTR'. *Note Flags for Sigaction::. - (sigmask (SIGTSTP) | sigmask (SIGSTOP) - | sigmask (SIGTTIN) | sigmask (SIGTTOU)) + Another way to specify the choice is with the `siginterrupt' +function. *Note BSD Handler::. - specifies a mask that includes all the job-control stop signals. + When you don't specify with `sigaction' or `siginterrupt' what a +particular handler should do, it uses a default choice. The default +choice in the GNU library depends on the feature test macros you have +defined. If you define `_BSD_SOURCE' or `_GNU_SOURCE' before calling +`signal', the default is to resume primitives; otherwise, the default +is to make them fail with `EINTR'. (The library contains alternate +versions of the `signal' function, and the feature test macros +determine which one you really call.) *Note Feature Test Macros::. - - Function: int sigblock (int MASK) - This function is equivalent to `sigprocmask' (*note Process Signal - Mask::) with a HOW argument of `SIG_BLOCK': it adds the signals - specified by MASK to the calling process's set of blocked signals. - The return value is the previous set of blocked signals. + The description of each primitive affected by this issue lists +`EINTR' among the error codes it can return. - - Function: int sigsetmask (int MASK) - This function equivalent to `sigprocmask' (*note Process Signal - Mask::) with a HOW argument of `SIG_SETMASK': it sets the calling - process's signal mask to MASK.

It is -up to you to write a function named `main'--otherwise, you won't even -be able to link your program without errors. + A process can send itself a signal with the `raise' function. This +function is declared in `signal.h'. - In ISO C you can define `main' either to take no arguments, or to -take two arguments that represent the command line arguments to the -program, like this: + - Function: int raise (int SIGNUM) + The `raise' function sends the signal SIGNUM to the calling + process. It returns zero if successful and a nonzero value if it + fails. About the only reason for failure would be if the value of + SIGNUM is invalid. - int main (int ARGC, char *ARGV[]) + - Function: int gsignal (int SIGNUM) + The `gsignal' function does the same thing as `raise'; it is + provided only for compatibility with SVID. - The command line arguments are the whitespace-separated tokens given -in the shell command used to invoke the program; thus, in `cat foo -bar', the arguments are `foo' and `bar'. The only way a program can -look at its command line arguments is via the arguments of `main'. If -`main' doesn't take arguments, then you cannot get at the command line. + One convenient use for `raise' is to reproduce the default behavior +of a signal that you have trapped. For instance, suppose a user of your +program types the SUSP character (usually `C-z'; *note Special +Characters::) to send it an interactive stop signal (`SIGTSTP'), and +you want to clean up some internal data buffers before stopping. You +might set this up like this: - The value of the ARGC argument is the number of command line -arguments. The ARGV argument is a vector of C strings; its elements -are the individual command line argument strings. The file name of the -program being run is also included in the vector as the first element; -the value of ARGC counts this element. A null pointer always follows -the last element: `ARGV[ARGC]' is this null pointer. + #include + + /* When a stop signal arrives, set the action back to the default + and then resend the signal after doing cleanup actions. */ + + void + tstp_handler (int sig) + { + signal (SIGTSTP, SIG_DFL); + /* Do cleanup actions here. */ + ... + raise (SIGTSTP); + } + + /* When the process is continued again, restore the signal handler. */ + + void + cont_handler (int sig) + { + signal (SIGCONT, cont_handler); + signal (SIGTSTP, tstp_handler); + } + + /* Enable both handlers during program initialization. */ + + int + main (void) + { + signal (SIGCONT, cont_handler); + signal (SIGTSTP, tstp_handler); + ... + } - For the command `cat foo bar', ARGC is 3 and ARGV has three -elements, `"cat"', `"foo"' and `"bar"'. + *Portability note:* `raise' was invented by the ISO C committee. +Older systems may not support it, so using `kill' may be more portable. +*Note Signaling Another Process::. - In Unix systems you can define `main' a third way, using three -arguments: + +File: libc.info, Node: Signaling Another Process, Next: Permission for kill, Prev: Signaling Yourself, Up: Generating Signals - int main (int ARGC, char *ARGV[], char *ENVP[]) +Signaling Another Process +------------------------- - The first two arguments are just the same.

POSIX.1 does not allow this -three-argument form, so to be portable it is best to write `main' to -take two arguments, and use the value of `environ'. + The `kill' function can be used to send a signal to another process. +In spite of its name, it can be used for a lot of things other than +causing a process to terminate. Some examples of situations where you +might want to send signals between processes are: -* Menu: + * A parent process starts a child to perform a task--perhaps having + the child running an infinite loop--and then terminates the child + when the task is no longer needed. -* Argument Syntax:: By convention, options start with a hyphen. -* Parsing Program Arguments:: Ways to parse program options and arguments. + * A process executes as part of a group, and needs to terminate or + notify the other processes in the group when an error or other + event occurs. - -File: libc.info, Node: Argument Syntax, Next: Parsing Program Arguments, Up: Program Arguments + * Two processes need to synchronize while working together. -Program Argument Syntax Conventions ------------------------------------ + This section assumes that you know a little bit about how processes +work.

Besides the signals listed in + *Note Standard Signals::, SIGNUM can also have a value of zero to + check the validity of the PID. - * Multiple options may follow a hyphen delimiter in a single token if - the options do not take arguments. Thus, `-abc' is equivalent to - `-a -b -c'. + The PID specifies the process or process group to receive the + signal: - * Option names are single alphanumeric characters (as for `isalnum'; - *note Classification of Characters::). + `PID > 0' + The process whose identifier is PID. - * Certain options require an argument.

They do this by reordering the elements of - the ARGV array. This behavior is nonstandard; if you want to - suppress it, define the `_POSIX_OPTION_ORDER' environment variable. - *Note Standard Environment::. + A process can send a signal to itself with a call like + `kill (getpid(), SIGNUM)'. If `kill' is used by a process to send + a signal to itself, and the signal is not blocked, then `kill' + delivers at least one signal (which might be some other pending + unblocked signal instead of the signal SIGNUM) to that process + before it returns. - * The argument `--' terminates all options; any following arguments - are treated as non-option arguments, even if they begin with a - hyphen. + The return value from `kill' is zero if the signal can be sent + successfully. Otherwise, no signal is sent, and a value of `-1' is + returned. If PID specifies sending a signal to several processes, + `kill' succeeds if it can send the signal to at least one of them. + There's no way you can tell which of the processes got the signal + or whether all of them did. - * A token consisting of a single hyphen character is interpreted as - an ordinary non-option argument.

Long options consist -of `--' followed by a name made of alphanumeric characters and dashes. -Option names are typically one to three words long, with hyphens to -separate words. Users can abbreviate the option names as long as the -abbreviations are unique. + `EPERM' + You do not have the privilege to send a signal to the process + or any of the processes in the process group named by PID. - To specify an argument for a long option, write `--NAME=VALUE'. -This syntax enables a long option to accept an argument that is itself -optional. + `ESCRH' + The PID argument does not refer to an existing process or + group. - Eventually, the GNU system will provide completion for long option -names in the shell. + - Function: int killpg (int PGID, int SIGNUM) + This is similar to `kill', but sends signal SIGNUM to the process + group PGID. This function is provided for compatibility with BSD; + using `kill' to do this is more portable. + + As a simple example of `kill', the call `kill (getpid (), SIG)' has +the same effect as `raise (SIG)'.  -File: libc.info, Node: Parsing Program Arguments, Prev: Argument Syntax, Up: Program Arguments +File: libc.info, Node: Permission for kill, Next: Kill Example, Prev: Signaling Another Process, Up: Generating Signals -Parsing Program Arguments -------------------------- +Permission for using `kill' +--------------------------- - If the syntax for the command line arguments to your program is -simple enough, you can simply pick the arguments off from ARGV by hand. -But unless your program takes a fixed number of arguments, or all of the -arguments are interpreted in the same way (as file names, for example), -you are usually better off using `getopt' (*note Getopt::) or -`argp_parse' (*note Argp::) to do the parsing. + There are restrictions that prevent you from using `kill' to send +signals to any random process.

The special argument `--' forces in - all cases the end of option scanning. + +File: libc.info, Node: Why Block, Next: Signal Sets, Up: Blocking Signals - * The default is to permute the contents of ARGV while scanning - it so that eventually all the non-options are at the end. - This allows options to be given in any order, even with - programs that were not written to expect this. +Why Blocking Signals is Useful +------------------------------ - * If the OPTIONS argument string begins with a hyphen (`-'), - this is treated specially. It permits arguments that are not - options to be returned as if they were associated with option - character `\1'. + Temporary blocking of signals with `sigprocmask' gives you a way to +prevent interrupts during critical parts of your code. If signals +arrive in that part of the program, they are delivered later, after you +unblock them. - * POSIX demands the following behavior: The first non-option - stops option processing. This mode is selected by either - setting the environment variable `POSIXLY_CORRECT' or - beginning the OPTIONS argument string with a plus sign (`+'). + One example where this is useful is for sharing data between a signal +handler and the rest of the program. If the type of the data is not +`sig_atomic_t' (*note Atomic Data Access::), then the signal handler +could run when the rest of the program has only half finished reading +or writing the data. This would lead to confusing consequences. - The `getopt' function returns the option character for the next - command line option. When no more option arguments are available, - it returns `-1'. There may still be more non-option arguments; you - must compare the external variable `optind' against the ARGC - parameter to check this. + To make the program reliable, you can prevent the signal handler from +running while the rest of the program is examining or modifying that +data--by blocking the appropriate signal around the parts of the +program that touch the data. - If the option has an argument, `getopt' returns the argument by - storing it in the variable OPTARG. You don't ordinarily need to - copy the `optarg' string, since it is a pointer into the original - ARGV array, not into a static area that might be overwritten. + Blocking signals is also necessary when you want to perform a certain +action only if a signal has not arrived. Suppose that the handler for +the signal sets a flag of type `sig_atomic_t'; you would like to test +the flag and perform the action if the flag is not set. This is +unreliable. Suppose the signal is delivered immediately after you test +the flag, but before the consequent action: then the program will +perform the action even though the signal has arrived. - If `getopt' finds an option character in ARGV that was not - included in OPTIONS, or a missing option argument, it returns `?' - and sets the external variable `optopt' to the actual option - character. If the first character of OPTIONS is a colon (`:'), - then `getopt' returns `:' instead of `?' to indicate a missing - option argument. In addition, if the external variable `opterr' - is nonzero (which is the default), `getopt' prints an error - message. + The only way to test reliably for whether a signal has yet arrived +is to test while the signal is blocked.  -File: libc.info, Node: Example of Getopt, Next: Getopt Long Options, Prev: Using Getopt, Up: Getopt +File: libc.info, Node: Signal Sets, Next: Process Signal Mask, Prev: Why Block, Up: Blocking Signals -Example of Parsing Arguments with `getopt' ------------------------------------------- +Signal Sets +----------- - Here is an example showing how `getopt' is typically used. The key -points to notice are: + All of the signal blocking functions use a data structure called a +"signal set" to specify what signals are affected. Thus, every +activity involves two stages: creating the signal set, and then passing +it as an argument to a library function. - * Normally, `getopt' is called in a loop. When `getopt' returns - `-1', indicating no more options are present, the loop terminates. + These facilities are declared in the header file `signal.h'. - * A `switch' statement is used to dispatch on the return value from - `getopt'. In typical use, each case just sets a variable that is - used later in the program. + - Data Type: sigset_t + The `sigset_t' data type is used to represent a signal set. + Internally, it may be implemented as either an integer or structure + type. - * A second loop is used to process the remaining non-option - arguments. + For portability, use only the functions described in this section + to initialize, change, and retrieve information from `sigset_t' + objects--don't try to manipulate them directly. - #include - #include - - int - main (int argc, char **argv) - { - int aflag = 0; - int bflag = 0; - char *cvalue = NULL; - int index; - int c; - - opterr = 0; - - while ((c = getopt (argc, argv, "abc:")) != -1) - switch (c) - { - case 'a': - aflag = 1; - break; - case 'b': - bflag = 1; - break; - case 'c': - cvalue = optarg; - break; - case '?': - if (isprint (optopt)) - fprintf (stderr, "Unknown option `-%c'.\n", optopt); - else - fprintf (stderr, - "Unknown option character `\\x%x'.\n", - optopt); - return 1; - default: - abort (); - } - - printf ("aflag = %d, bflag = %d, cvalue = %s\n", - aflag, bflag, cvalue); - - for (index = optind; index < argc; index++) - printf ("Non-option argument %s\n", argv[index]); - return 0; - } + There are two ways to initialize a signal set. You can initially +specify it to be empty with `sigemptyset' and then add specified +signals individually. Or you can specify it to be full with +`sigfillset' and then delete specified signals individually. - Here are some examples showing what this program prints with -different combinations of arguments: + You must always initialize the signal set with one of these two +functions before using it in any other way. Don't try to set all the +signals explicitly because the `sigset_t' object might include some +other information (like a version field) that needs to be initialized as +well.

The + following `errno' error condition is defined for this function: - - Data Type: struct option - This structure describes a single long option name for the sake of - `getopt_long'. The argument LONGOPTS must be an array of these - structures, one for each long option.

The return value and error conditions are the same + as for `sigaddset'. - `const char *name' - This field is the name of the option. It is a string. + Finally, there is a function to test what signals are in a signal +set: - `int has_arg' - This field says whether the option takes an argument. It is - an integer, and there are three legitimate values: - `no_argument', `required_argument' and `optional_argument'. + - Function: int sigismember (const sigset_t *SET, int SIGNUM) + The `sigismember' function tests whether the signal SIGNUM is a + member of the signal set SET. It returns `1' if the signal is in + the set, `0' if not, and `-1' if there is an error. - `int *flag' - `int val' - These fields control how to report or act on the option when - it occurs. + The following `errno' error condition is defined for this function: - If `flag' is a null pointer, then the `val' is a value which - identifies this option. Often these values are chosen to - uniquely identify particular long options. + `EINVAL' + The SIGNUM argument doesn't specify a valid signal. - If `flag' is not a null pointer, it should be the address of - an `int' variable which is the flag for this option.

The - argument SHORTOPTS describes the short options to accept, just as - it does in `getopt'. The argument LONGOPTS describes the long - options to accept (see above). +Process Signal Mask +------------------- - When `getopt_long' encounters a short option, it does the same - thing that `getopt' would do: it returns the character code for the - option, and stores the options argument (if it has one) in - `optarg'. + The collection of signals that are currently blocked is called the +"signal mask". Each process has its own signal mask. When you create +a new process (*note Creating a Process::), it inherits its parent's +mask. You can block or unblock signals with total flexibility by +modifying the signal mask. - When `getopt_long' encounters a long option, it takes actions based - on the `flag' and `val' fields of the definition of that option. + The prototype for the `sigprocmask' function is in `signal.h'. - If `flag' is a null pointer, then `getopt_long' returns the - contents of `val' to indicate which option it found. You should - arrange distinct values in the `val' field for options with - different meanings, so you can decode these values after - `getopt_long' returns. If the long option is equivalent to a short - option, you can use the short option's character code in `val'. + - Function: int sigprocmask (int HOW, const sigset_t *restrict SET, + sigset_t *restrict OLDSET) + The `sigprocmask' function is used to examine or change the calling + process's signal mask. The HOW argument determines how the signal + mask is changed, and must be one of the following values: - If `flag' is not a null pointer, that means this option should just - set a flag in the program. The flag is a variable of type `int' - that you define. Put the address of the flag in the `flag' field. - Put in the `val' field the value you would like this option to - store in the flag. In this case, `getopt_long' returns `0'. + `SIG_BLOCK' + Block the signals in `set'--add them to the existing mask. In + other words, the new mask is the union of the existing mask + and SET. - For any long option, `getopt_long' tells you the index in the array - LONGOPTS of the options definition, by storing it into - `*INDEXPTR'. You can get the name of the option with - `LONGOPTS[*INDEXPTR].name'. So you can distinguish among long - options either by the values in their `val' fields or by their - indices. You can also distinguish in this way among long options - that set flags. + `SIG_UNBLOCK' + Unblock the signals in SET--remove them from the existing + mask. - When a long option has an argument, `getopt_long' puts the argument - value in the variable `optarg' before returning. When the option - has no argument, the value in `optarg' is a null pointer. This is - how you can tell whether an optional argument was supplied. + `SIG_SETMASK' + Use SET for the mask; ignore the previous value of the mask. - When `getopt_long' has no more options to handle, it returns `-1', - and leaves in the variable `optind' the index in ARGV of the next - remaining argument. + The last argument, OLDSET, is used to return information about the + old process signal mask. If you just want to change the mask + without looking at it, pass a null pointer as the OLDSET argument. + Similarly, if you want to know what's in the mask without changing + it, pass a null pointer for SET (in this case the HOW argument is + not significant). The OLDSET argument is often used to remember + the previous signal mask in order to restore it later. (Since the + signal mask is inherited over `fork' and `exec' calls, you can't + predict what its contents are when your program starts running.) - Since long option names were used before before the `getopt_long' -options was invented there are program interfaces which require programs -to recognize options like `-option value' instead of `--option value'. -To enable these programs to use the GNU getopt functionality there is -one more function available. + If invoking `sigprocmask' causes any pending signals to be + unblocked, at least one of those signals is delivered to the + process before `sigprocmask' returns. The order in which pending + signals are delivered is not specified, but you can control the + order explicitly by making multiple `sigprocmask' calls to unblock + various signals one at a time. - - Function: int getopt_long_only (int ARGC, char *const *ARGV, const - char *SHORTOPTS, struct option *LONGOPTS, int *INDEXPTR) - The `getopt_long_only' function is equivalent to the `getopt_long' - function but it allows to specify the user of the application to - pass long options with only `-' instead of `--'. The `--' prefix - is still recognized but instead of looking through the short - options if a `-' is seen it is first tried whether this parameter - names a long option. If not, it is parsed as a short option. + The `sigprocmask' function returns `0' if successful, and `-1' to + indicate an error. The following `errno' error conditions are + defined for this function: - Assuming `getopt_long_only' is used starting an application with + `EINVAL' + The HOW argument is invalid. - app -foo + You can't block the `SIGKILL' and `SIGSTOP' signals, but if the + signal set includes these, `sigprocmask' just ignores them instead + of returning an error status. - the `getopt_long_only' will first look for a long option named - `foo'. If this is not found, the short options `f', `o', and - again `o' are recognized. + Remember, too, that blocking program error signals such as `SIGFPE' + leads to undesirable results for signals generated by an actual + program error (as opposed to signals sent with `raise' or `kill'). + This is because your program may be too broken to be able to + continue executing to a point where the signal is unblocked again. + *Note Program Error Signals::.  -File: libc.info, Node: Getopt Long Option Example, Prev: Getopt Long Options, Up: Getopt +File: libc.info, Node: Testing for Delivery, Next: Blocking for Handler, Prev: Process Signal Mask, Up: Blocking Signals -Example of Parsing Long Options with `getopt_long' --------------------------------------------------- +Blocking to Test for Delivery of a Signal +----------------------------------------- - #include - #include - #include - - /* Flag set by `--verbose'. */ - static int verbose_flag; + Now for a simple example.

By convention, the documentation before the - options is just a short string explaining what the program - does. Documentation printed after the options describe - behavior in more detail. + Note how the particular signal that arrives is stored in +`signal_pending'. That way, we can handle several types of +inconvenient signals with the same mechanism. - `const struct argp_child *children' - A pointer to a vector of `argp_children' structures. This - pointer specifies which additional argp parsers should be - combined with this one. *Note Argp Children::. + We increment and decrement `defer_signal' so that nested critical +sections will work properly; thus, if `update_mumble' were called with +`signal_pending' already nonzero, signals would be deferred not only +within `update_mumble', but also within the caller.

But that does not cause any problem. If the signal happens +early enough to see the value from before the increment or decrement, +that is equivalent to a signal which came before the beginning of the +increment or decrement, which is a case that works properly. - `const char *argp_domain' - If non-zero, the strings used in the argp library are - translated using the domain described by this string.

If an argp parser is defined -as an initialized C variable, only the fields used need be specified in -the initializer. The rest will default to zero due to the way C -structure initialization works. This design is exploited in most argp -structures; the most-used fields are grouped near the beginning, the -unused fields left unspecified. +then a signal arriving in between the `if' statement and the decrement +would be effectively "lost" for an indefinite amount of time.

Multiple entries may be used for a single option -provided it has multiple names. This should be terminated by an entry -with zero in all fields. Note that when using an initialized C array -for options, writing `{ 0 }' is enough to achieve this. +Waiting for a Signal +==================== - - Data Type: struct argp_option - This structure specifies a single option that an argp parser - understands, as well as how to parse and document that option. It - has the following fields: + If your program is driven by external events, or uses signals for +synchronization, then when it has nothing to do it should probably wait +until a signal arrives. - `const char *name' - The long name for this option, corresponding to the long - option `--NAME'; this field may be zero if this option _only_ - has a short name. To specify multiple names for an option, - additional entries may follow this one, with the - `OPTION_ALIAS' flag set. *Note Argp Option Flags::. +* Menu: - `int key' - The integer key provided by the current option to the option - parser. If KEY has a value that is a printable ASCII - character (i.e., `isascii (KEY)' is true), it _also_ - specifies a short option `-CHAR', where CHAR is the ASCII - character with the code KEY. +* Using Pause:: The simple way, using `pause'. +* Pause Problems:: Why the simple way is often not very good. +* Sigsuspend:: Reliably waiting for a specific signal. - `const char *arg' - If non-zero, this is the name of an argument associated with - this option, which must be provided (e.g., with the - `--NAME=VALUE' or `-CHAR VALUE' syntaxes), unless the - `OPTION_ARG_OPTIONAL' flag (*note Argp Option Flags::) is - set, in which case it _may_ be provided. + +File: libc.info, Node: Using Pause, Next: Pause Problems, Up: Waiting for a Signal - `int flags' - Flags associated with this option, some of which are referred - to above. *Note Argp Option Flags::. +Using `pause' +------------- - `const char *doc' - A documentation string for this option, for printing in help - messages. + The simple way to wait until a signal arrives is to call `pause'. +Please read about its disadvantages, in the following section, before +you use it. - If both the `name' and `key' fields are zero, this string - will be printed tabbed left from the normal option column, - making it useful as a group header. This will be the first - thing printed in its group. In this usage, it's conventional - to end the string with a `:' character. + - Function: int pause () + The `pause' function suspends program execution until a signal + arrives whose action is either to execute a handler function, or to + terminate the process. - `int group' - Group identity for this option. + If the signal causes a handler function to be executed, then + `pause' returns. This is considered an unsuccessful return (since + "successful" behavior would be to suspend the program forever), so + the return value is `-1'. Even if you specify that other + primitives should resume when a system handler returns (*note + Interrupted Primitives::), this has no effect on `pause'; it + always fails when a signal is handled. - In a long help message, options are sorted alphabetically - within each group, and the groups presented in the order 0, - 1, 2, ..., N, -M, ..., -2, -1. + The following `errno' error conditions are defined for this + function: - Every entry in an options array with this field 0 will - inherit the group number of the previous entry, or zero if - it's the first one. If it's a group header with `name' and - `key' fields both zero, the previous entry + 1 is the - default. Automagic options such as `--help' are put into - group -1. + `EINTR' + The function was interrupted by delivery of a signal. - Note that because of C structure initialization rules, this - field often need not be specified, because 0 is the correct - value. + If the signal causes program termination, `pause' doesn't return + (obviously). -* Menu: + This function is a cancellation point in multithreaded programs. + This is a problem if the thread allocates some resources (like + memory, file descriptors, semaphores or whatever) at the time + `pause' is called. If the thread gets cancelled these resources + stay allocated until the program ends. To avoid this calls to + `pause' should be protected using cancellation handlers. -* Flags: Argp Option Flags. Flags for options. + The `pause' function is declared in `unistd.h'.  -File: libc.info, Node: Argp Option Flags, Up: Argp Option Vectors +File: libc.info, Node: Pause Problems, Next: Sigsuspend, Prev: Using Pause, Up: Waiting for a Signal -Flags for Argp Options -...................... +Problems with `pause' +--------------------- - The following flags may be or'd together in the `flags' field of a -`struct argp_option'. These flags control various aspects of how that -option is parsed or displayed in help messages: + The simplicity of `pause' can conceal serious timing errors that can +make a program hang mysteriously. -`OPTION_ARG_OPTIONAL' - The argument associated with this option is optional. + It is safe to use `pause' if the real work of your program is done +by the signal handlers themselves, and the "main program" does nothing +but call `pause'. Each time a signal is delivered, the handler will do +the next batch of work that is to be done, and then return, so that the +main loop of the program can call `pause' again. -`OPTION_HIDDEN' - This option isn't displayed in any help messages. + You can't safely use `pause' to wait until one more signal arrives, +and then resume real work. Even if you arrange for the signal handler +to cooperate by setting a flag, you still can't use `pause' reliably. +Here is an example of this problem: -`OPTION_ALIAS' - This option is an alias for the closest previous non-alias option. - This means that it will be displayed in the same help entry, and - will inherit fields other than `name' and `key' from the option - being aliased. + /* `usr_interrupt' is set by the signal handler. */ + if (!usr_interrupt) + pause (); + + /* Do work once the signal arrives. */ + ... -`OPTION_DOC' - This option isn't actually an option and should be ignored by the - actual option parser. It is an arbitrary section of documentation - that should be displayed in much the same manner as the options. - This is known as a "documentation option". +This has a bug: the signal could arrive after the variable +`usr_interrupt' is checked, but before the call to `pause'. If no +further signals arrive, the process would never wake up again. - If this flag is set, then the option `name' field is displayed - unmodified (e.g., no `--' prefix is added) at the left-margin where - a _short_ option would normally be displayed, and this - documentation string is left in it's usual place. For purposes of - sorting, any leading whitespace and punctuation is ignored, unless - the first non-whitespace character is `-'. This entry is displayed - after all options, after `OPTION_DOC' entries with a leading `-', - in the same group. + You can put an upper limit on the excess waiting by using `sleep' in +a loop, instead of using `pause'. (*Note Sleeping::, for more about +`sleep'.) Here is what this looks like: -`OPTION_NO_USAGE' - This option shouldn't be included in `long' usage messages, but - should still be included in other help messages. This is intended - for options that are completely documented in an argp's `args_doc' - field. *Note Argp Parsers::. Including this option in the - generic usage list would be redundant, and should be avoided. + /* `usr_interrupt' is set by the signal handler. + while (!usr_interrupt) + sleep (1); + + /* Do work once the signal arrives. */ + ... - For instance, if `args_doc' is `"FOO BAR\n-x BLAH"', and the `-x' - option's purpose is to distinguish these two cases, `-x' should - probably be marked `OPTION_NO_USAGE'. + For some purposes, that is good enough. But with a little more +complexity, you can wait reliably until a particular signal handler is +run, using `sigsuspend'. *Note Sigsuspend::.  -File: libc.info, Node: Argp Parser Functions, Next: Argp Children, Prev: Argp Option Vectors, Up: Argp Parsers +File: libc.info, Node: Sigsuspend, Prev: Pause Problems, Up: Waiting for a Signal -Argp Parser Functions ---------------------- +Using `sigsuspend' +------------------ - The function pointed to by the `parser' field in a `struct argp' -(*note Argp Parsers::) defines what actions take place in response to -each option or argument parsed. It is also used as a hook, allowing a -parser to perform tasks at certain other points during parsing. + The clean and reliable way to wait for a signal to arrive is to +block it and then use `sigsuspend'. By using `sigsuspend' in a loop, +you can wait for certain kinds of signals, while letting other kinds of +signals be handled by their handlers. - Argp parser functions have the following type signature: + - Function: int sigsuspend (const sigset_t *SET) + This function replaces the process's signal mask with SET and then + suspends the process until a signal is delivered whose action is + either to terminate the process or invoke a signal handling + function. In other words, the program is effectively suspended + until one of the signals that is not a member of SET arrives. - error_t PARSER (int KEY, char *ARG, struct argp_state *STATE) + If the process is woken up by delivery of a signal that invokes a + handler function, and the handler function returns, then + `sigsuspend' also returns. -where the arguments are as follows: + The mask remains SET only as long as `sigsuspend' is waiting. The + function `sigsuspend' always restores the previous signal mask + when it returns. -KEY - For each option that is parsed, PARSER is called with a value of - KEY from that option's `key' field in the option vector. *Note - Argp Option Vectors::. PARSER is also called at other times with - special reserved keys, such as `ARGP_KEY_ARG' for non-option - arguments. *Note Argp Special Keys::. + The return value and error conditions are the same as for `pause'. -ARG - If KEY is an option, ARG is its given value. This defaults to - zero if no value is specified. Only options that have a non-zero - `arg' field can ever have a value. These must _always_ have a - value unless the `OPTION_ARG_OPTIONAL' flag is specified. If the - input being parsed specifies a value for an option that doesn't - allow one, an error results before PARSER ever gets called. + With `sigsuspend', you can replace the `pause' or `sleep' loop in +the previous section with something completely reliable: - If KEY is `ARGP_KEY_ARG', ARG is a non-option argument. Other - special keys always have a zero ARG. + sigset_t mask, oldmask; + + ... + + /* Set up the mask of signals to temporarily block. */ + sigemptyset (&mask); + sigaddset (&mask, SIGUSR1); + + ... + + /* Wait for a signal to arrive. */ + sigprocmask (SIG_BLOCK, &mask, &oldmask); + while (!usr_interrupt) + sigsuspend (&oldmask); + sigprocmask (SIG_UNBLOCK, &mask, NULL); -STATE - STATE points to a `struct argp_state', containing useful - information about the current parsing state for use by PARSER. - *Note Argp Parsing State::. + This last piece of code is a little tricky. The key point to +remember here is that when `sigsuspend' returns, it resets the process's +signal mask to the original value, the value from before the call to +`sigsuspend'--in this case, the `SIGUSR1' signal is once again blocked. +The second call to `sigprocmask' is necessary to explicitly unblock +this signal. - When PARSER is called, it should perform whatever action is -appropriate for KEY, and return `0' for success, `ARGP_ERR_UNKNOWN' if -the value of KEY is not handled by this parser function, or a unix -error code if a real error occurred. *Note Error Codes::. + One other point: you may be wondering why the `while' loop is +necessary at all, since the program is apparently only waiting for one +`SIGUSR1' signal. The answer is that the mask passed to `sigsuspend' +permits the process to be woken up by the delivery of other kinds of +signals, as well--for example, job control signals. If the process is +woken up by a signal that doesn't set `usr_interrupt', it just suspends +itself again until the "right" kind of signal eventually arrives. - - Macro: int ARGP_ERR_UNKNOWN - Argp parser functions should return `ARGP_ERR_UNKNOWN' for any KEY - value they do not recognize, or for non-option arguments (`KEY == - ARGP_KEY_ARG') that they are not equipped to handle. + This technique takes a few more lines of preparation, but that is +needed just once for each kind of wait criterion you want to use. The +code that actually waits is just four lines. - A typical parser function uses a switch statement on KEY: + +File: libc.info, Node: Signal Stack, Next: BSD Signal Handling, Prev: Waiting for a Signal, Up: Signal Handling - error_t - parse_opt (int key, char *arg, struct argp_state *state) - { - switch (key) - { - case OPTION_KEY: - ACTION - break; - ... - default: - return ARGP_ERR_UNKNOWN; - } - return 0; - } +Using a Separate Signal Stack +============================= -* Menu: + A signal stack is a special area of memory to be used as the +execution stack during signal handlers. It should be fairly large, to +avoid any danger that it will overflow in turn; the macro `SIGSTKSZ' is +defined to a canonical size for signal stacks. You can use `malloc' to +allocate the space for the stack. Then call `sigaltstack' or +`sigstack' to tell the system to use that space for the signal stack. -* Keys: Argp Special Keys. Special values for the KEY argument. -* State: Argp Parsing State. What the STATE argument refers to. -* Functions: Argp Helper Functions. Functions to help during argp parsing. + You don't need to write signal handlers differently in order to use a +signal stack. Switching from one stack to the other happens +automatically. (Some non-GNU debuggers on some machines may get +confused if you examine a stack trace while a handler that uses the +signal stack is running.) - -File: libc.info, Node: Argp Special Keys, Next: Argp Parsing State, Up: Argp Parser Functions + There are two interfaces for telling the system to use a separate +signal stack. `sigstack' is the older interface, which comes from 4.2 +BSD. `sigaltstack' is the newer interface, and comes from 4.4 BSD. +The `sigaltstack' interface has the advantage that it does not require +your program to know which direction the stack grows, which depends on +the specific machine and operating system. -Special Keys for Argp Parser Functions -...................................... + - Data Type: stack_t + This structure describes a signal stack. It contains the + following members: - In addition to key values corresponding to user options, the KEY -argument to argp parser functions may have a number of other special -values. In the following example ARG and STATE refer to parser -function arguments. *Note Argp Parser Functions::. + `void *ss_sp' + This points to the base of the signal stack. -`ARGP_KEY_ARG' - This is not an option at all, but rather a command line argument, - whose value is pointed to by ARG. + `size_t ss_size' + This is the size (in bytes) of the signal stack which `ss_sp' + points to. You should set this to however much space you + allocated for the stack. - When there are multiple parser functions in play due to argp - parsers being combined, it's impossible to know which one will - handle a specific argument. Each is called until one returns 0 or - an error other than `ARGP_ERR_UNKNOWN'; if an argument is not - handled, `argp_parse' immediately returns success, without parsing - any more arguments. + There are two macros defined in `signal.h' that you should + use in calculating this size: - Once a parser function returns success for this key, that fact is - recorded, and the `ARGP_KEY_NO_ARGS' case won't be used. - _However_, if while processing the argument a parser function - decrements the `next' field of its STATE argument, the option - won't be considered processed; this is to allow you to actually - modify the argument, perhaps into an option, and have it processed - again. + `SIGSTKSZ' + This is the canonical size for a signal stack. It is + judged to be sufficient for normal uses. -`ARGP_KEY_ARGS' - If a parser function returns `ARGP_ERR_UNKNOWN' for - `ARGP_KEY_ARG', it is immediately called again with the key - `ARGP_KEY_ARGS', which has a similar meaning, but is slightly more - convenient for consuming all remaining arguments. ARG is 0, and - the tail of the argument vector may be found at `STATE->argv + - STATE->next'. If success is returned for this key, and - `STATE->next' is unchanged, all remaining arguments are considered - to have been consumed. Otherwise, the amount by which - `STATE->next' has been adjusted indicates how many were used. - Here's an example that uses both, for different args: + `MINSIGSTKSZ' + This is the amount of signal stack space the operating + system needs just to implement signal delivery. The + size of a signal stack *must* be greater than this. - ... - case ARGP_KEY_ARG: - if (STATE->arg_num == 0) - /* First argument */ - first_arg = ARG; - else - /* Let the next case parse it. */ - return ARGP_KEY_UNKNOWN; - break; - case ARGP_KEY_ARGS: - remaining_args = STATE->argv + STATE->next; - num_remaining_args = STATE->argc - STATE->next; - break; + For most cases, just using `SIGSTKSZ' for `ss_size' is + sufficient. But if you know how much stack space your + program's signal handlers will need, you may want to use + a different size. In this case, you should allocate + `MINSIGSTKSZ' additional bytes for the signal stack and + increase `ss_size' accordingly. -`ARGP_KEY_END' - This indicates that there are no more command line arguments. - Parser functions are called in a different order, children first. - This allows each parser to clean up its state for the parent. + `int ss_flags' + This field contains the bitwise OR of these flags: -`ARGP_KEY_NO_ARGS' - Because it's common to do some special processing if there aren't - any non-option args, parser functions are called with this key if - they didn't successfully process any non-option arguments. This - is called just before `ARGP_KEY_END', where more general validity - checks on previously parsed arguments take place. + `SS_DISABLE' + This tells the system that it should not use the signal + stack. -`ARGP_KEY_INIT' - This is passed in before any parsing is done. Afterwards, the - values of each element of the `child_input' field of STATE, if - any, are copied to each child's state to be the initial value of - the `input' when _their_ parsers are called. + `SS_ONSTACK' + This is set by the system, and indicates that the signal + stack is currently in use. If this bit is not set, then + signals will be delivered on the normal user stack. -`ARGP_KEY_SUCCESS' - Passed in when parsing has successfully been completed, even if - arguments remain. + - Function: int sigaltstack (const stack_t *restrict STACK, stack_t + *restrict OLDSTACK) + The `sigaltstack' function specifies an alternate stack for use + during signal handling. When a signal is received by the process + and its action indicates that the signal stack is used, the system + arranges a switch to the currently installed signal stack while + the handler for that signal is executed. -`ARGP_KEY_ERROR' - Passed in if an error has occurred and parsing is terminated. In - this case a call with a key of `ARGP_KEY_SUCCESS' is never made. + If OLDSTACK is not a null pointer, information about the currently + installed signal stack is returned in the location it points to. + If STACK is not a null pointer, then this is installed as the new + stack for use by signal handlers. -`ARGP_KEY_FINI' - The final key ever seen by any parser, even after - `ARGP_KEY_SUCCESS' and `ARGP_KEY_ERROR'. Any resources allocated - by `ARGP_KEY_INIT' may be freed here. At times, certain resources - allocated are to be returned to the caller after a successful - parse. In that case, those particular resources can be freed in - the `ARGP_KEY_ERROR' case. + The return value is `0' on success and `-1' on failure. If + `sigaltstack' fails, it sets `errno' to one of these values: - In all cases, `ARGP_KEY_INIT' is the first key seen by parser -functions, and `ARGP_KEY_FINI' the last, unless an error was returned -by the parser for `ARGP_KEY_INIT'. Other keys can occur in one the -following orders. OPT refers to an arbitrary option key: + `EINVAL' + You tried to disable a stack that was in fact currently in + use. -OPT... `ARGP_KEY_NO_ARGS' `ARGP_KEY_END' `ARGP_KEY_SUCCESS' - The arguments being parsed did not contain any non-option - arguments. + `ENOMEM' + The size of the alternate stack was too small. It must be + greater than `MINSIGSTKSZ'. -( OPT | `ARGP_KEY_ARG' )... `ARGP_KEY_END' `ARGP_KEY_SUCCESS' - All non-option arguments were successfully handled by a parser - function. There may be multiple parser functions if multiple argp - parsers were combined. + Here is the older `sigstack' interface. You should use +`sigaltstack' instead on systems that have it. -( OPT | `ARGP_KEY_ARG' )... `ARGP_KEY_SUCCESS' - Some non-option argument went unrecognized. + - Data Type: struct sigstack + This structure describes a signal stack. It contains the + following members: - This occurs when every parser function returns `ARGP_KEY_UNKNOWN' - for an argument, in which case parsing stops at that argument if - ARG_INDEX is a null pointer. Otherwise an error occurs. + `void *ss_sp' + This is the stack pointer. If the stack grows downwards on + your machine, this should point to the top of the area you + allocated.

Though it may have multiple threads +of control within the same program and a program may be composed of +multiple logically separate modules, a process always executes exactly +one program. - Where conflicts between combined parsers arise, as when two specify -an option with the same name, the parser conflicts are resolved in -favor of the parent argp parser(s), or the earlier of the argp parsers -in the list of children. + Note that we are using a specific definition of "program" for the +purposes of this manual, which corresponds to a common definition in the +context of Unix system.

It is +up to you to write a function named `main'--otherwise, you won't even +be able to link your program without errors. -Flags for `argp_parse' ----------------------- + In ISO C you can define `main' either to take no arguments, or to +take two arguments that represent the command line arguments to the +program, like this: - The default behavior of `argp_parse' is designed to be convenient -for the most common case of parsing program command line argument. To -modify these defaults, the following flags may be or'd together in the -FLAGS argument to `argp_parse': + int main (int ARGC, char *ARGV[]) -`ARGP_PARSE_ARGV0' - Don't ignore the first element of the ARGV argument to - `argp_parse'. Unless `ARGP_NO_ERRS' is set, the first element of - the argument vector is skipped for option parsing purposes, as it - corresponds to the program name in a command line. + The command line arguments are the whitespace-separated tokens given +in the shell command used to invoke the program; thus, in `cat foo +bar', the arguments are `foo' and `bar'. The only way a program can +look at its command line arguments is via the arguments of `main'. If +`main' doesn't take arguments, then you cannot get at the command line. -`ARGP_NO_ERRS' - Don't print error messages for unknown options to `stderr'; unless - this flag is set, `ARGP_PARSE_ARGV0' is ignored, as `argv[0]' is - used as the program name in the error messages. This flag implies - `ARGP_NO_EXIT'. This is based on the assumption that silent - exiting upon errors is bad behavior. + The value of the ARGC argument is the number of command line +arguments. The ARGV argument is a vector of C strings; its elements +are the individual command line argument strings. The file name of the +program being run is also included in the vector as the first element; +the value of ARGC counts this element. A null pointer always follows +the last element: `ARGV[ARGC]' is this null pointer. -`ARGP_NO_ARGS' - Don't parse any non-option args. Normally these are parsed by - calling the parse functions with a key of `ARGP_KEY_ARG', the - actual argument being the value. This flag needn't normally be - set, as the default behavior is to stop parsing as soon as an - argument fails to be parsed. *Note Argp Parser Functions::. + For the command `cat foo bar', ARGC is 3 and ARGV has three +elements, `"cat"', `"foo"' and `"bar"'. -`ARGP_IN_ORDER' - Parse options and arguments in the same order they occur on the - command line. Normally they're rearranged so that all options - come first. + In Unix systems you can define `main' a third way, using three +arguments: -`ARGP_NO_HELP' - Don't provide the standard long option `--help', which ordinarily - causes usage and option help information to be output to `stdout' - and `exit (0)'. + int main (int ARGC, char *ARGV[], char *ENVP[]) -`ARGP_NO_EXIT' - Don't exit on errors, although they may still result in error - messages. + The first two arguments are just the same. The third argument ENVP +gives the program's environment; it is the same as the value of +`environ'. *Note Environment Variables::. POSIX.1 does not allow this +three-argument form, so to be portable it is best to write `main' to +take two arguments, and use the value of `environ'. -`ARGP_LONG_ONLY' - Use the gnu getopt `long-only' rules for parsing arguments. This - allows long-options to be recognized with only a single `-' (i.e. - `-help'). This results in a less useful interface, and its use is - discouraged as it conflicts with the way most GNU programs work as - well as the GNU coding standards. +* Menu: -`ARGP_SILENT' - Turns off any message-printing/exiting options, specifically - `ARGP_NO_EXIT', `ARGP_NO_ERRS', and `ARGP_NO_HELP'. +* Argument Syntax:: By convention, options start with a hyphen. +* Parsing Program Arguments:: Ways to parse program options and arguments.  -File: libc.info, Node: Argp Help Filtering, Prev: Argp Children, Up: Argp Parsers - -Customizing Argp Help Output ----------------------------- +File: libc.info, Node: Argument Syntax, Next: Parsing Program Arguments, Up: Program Arguments - The `help_filter' field in a `struct argp' is a pointer to a -function that filters the text of help messages before displaying them. -They have a function signature like: +Program Argument Syntax Conventions +----------------------------------- - char *HELP-FILTER (int KEY, const char *TEXT, void *INPUT) + POSIX recommends these conventions for command line arguments. +`getopt' (*note Getopt::) and `argp_parse' (*note Argp::) make it easy +to implement them. -Where KEY is either a key from an option, in which case TEXT is that -option's help text. *Note Argp Option Vectors::.

It is made sure that concurrent modifications to the -environment do not lead to errors. + The following flags may be or'd together in the `flags' field of a +`struct argp_option'. These flags control various aspects of how that +option is parsed or displayed in help messages: - - Function: char * getenv (const char *NAME) - This function returns a string that is the value of the environment - variable NAME. You must not modify this string. In some non-Unix - systems not using the GNU library, it might be overwritten by - subsequent calls to `getenv' (but not by any other library - function). If the environment variable NAME is not defined, the - value is a null pointer. +`OPTION_ARG_OPTIONAL' + The argument associated with this option is optional. - - Function: int putenv (char *STRING) - The `putenv' function adds or removes definitions from the - environment. If the STRING is of the form `NAME=VALUE', the - definition is added to the environment. Otherwise, the STRING is - interpreted as the name of an environment variable, and any - definition for this variable in the environment is removed. +`OPTION_HIDDEN' + This option isn't displayed in any help messages. - The difference to the `setenv' function is that the exact string - given as the parameter STRING is put into the environment. If the - user should change the string after the `putenv' call this will - reflect in automatically in the environment. This also requires - that STRING is no automatic variable which scope is left before the - variable is removed from the environment. The same applies of - course to dynamically allocated variables which are freed later. +`OPTION_ALIAS' + This option is an alias for the closest previous non-alias option. + This means that it will be displayed in the same help entry, and + will inherit fields other than `name' and `key' from the option + being aliased. - This function is part of the extended Unix interface. Since it - was also available in old SVID libraries you should define either - _XOPEN_SOURCE or _SVID_SOURCE before including any header. +`OPTION_DOC' + This option isn't actually an option and should be ignored by the + actual option parser. It is an arbitrary section of documentation + that should be displayed in much the same manner as the options. + This is known as a "documentation option". - - Function: int setenv (const char *NAME, const char *VALUE, int - REPLACE) - The `setenv' function can be used to add a new definition to the - environment. The entry with the name NAME is replaced by the - value `NAME=VALUE'. Please note that this is also true if VALUE - is the empty string. To do this a new string is created and the - strings NAME and VALUE are copied. A null pointer for the VALUE - parameter is illegal. If the environment already contains an - entry with key NAME the REPLACE parameter controls the action. If - replace is zero, nothing happens. Otherwise the old entry is - replaced by the new one. + If this flag is set, then the option `name' field is displayed + unmodified (e.g., no `--' prefix is added) at the left-margin where + a _short_ option would normally be displayed, and this + documentation string is left in it's usual place. For purposes of + sorting, any leading whitespace and punctuation is ignored, unless + the first non-whitespace character is `-'.

If the environment contains an entry with the key - NAME this whole entry is removed.

The BSD version had no return value, - though. + The function pointed to by the `parser' field in a `struct argp' +(*note Argp Parsers::) defines what actions take place in response to +each option or argument parsed. It is also used as a hook, allowing a +parser to perform tasks at certain other points during parsing. - There is one more function to modify the whole environment. This -function is said to be used in the POSIX.9 (POSIX bindings for Fortran -77) and so one should expect it did made it into POSIX.1. But this -never happened. But we still provide this function as a GNU extension -to enable writing standard compliant Fortran environments. + Argp parser functions have the following type signature: - - Function: int clearenv (void) - The `clearenv' function removes all entries from the environment. - Using `putenv' and `setenv' new entries can be added again later. + error_t PARSER (int KEY, char *ARG, struct argp_state *STATE) - If the function is successful it returns `0'. Otherwise the return - value is nonzero. +where the arguments are as follows: - You can deal directly with the underlying representation of -environment objects to add more variables to the environment (for -example, to communicate with another program you are about to execute; -*note Executing a File::). +KEY + For each option that is parsed, PARSER is called with a value of + KEY from that option's `key' field in the option vector. *Note + Argp Option Vectors::. PARSER is also called at other times with + special reserved keys, such as `ARGP_KEY_ARG' for non-option + arguments. *Note Argp Special Keys::. - - Variable: char ** environ - The environment is represented as an array of strings. Each - string is of the format `NAME=VALUE'. The order in which strings - appear in the environment is not significant, but the same NAME - must not appear more than once. The last element of the array is - a null pointer. +ARG + If KEY is an option, ARG is its given value. This defaults to + zero if no value is specified. Only options that have a non-zero + `arg' field can ever have a value. These must _always_ have a + value unless the `OPTION_ARG_OPTIONAL' flag is specified. If the + input being parsed specifies a value for an option that doesn't + allow one, an error results before PARSER ever gets called. - This variable is declared in the header file `unistd.h'. + If KEY is `ARGP_KEY_ARG', ARG is a non-option argument. Other + special keys always have a zero ARG. - If you just want to get the value of an environment variable, use - `getenv'. +STATE + STATE points to a `struct argp_state', containing useful + information about the current parsing state for use by PARSER. + *Note Argp Parsing State::. - Unix systems, and the GNU system, pass the initial value of -`environ' as the third argument to `main'. *Note Program Arguments::. + When PARSER is called, it should perform whatever action is +appropriate for KEY, and return `0' for success, `ARGP_ERR_UNKNOWN' if +the value of KEY is not handled by this parser function, or a unix +error code if a real error occurred. *Note Error Codes::. - -File: libc.info, Node: Standard Environment, Prev: Environment Access, Up: Environment Variables + - Macro: int ARGP_ERR_UNKNOWN + Argp parser functions should return `ARGP_ERR_UNKNOWN' for any KEY + value they do not recognize, or for non-option arguments (`KEY == + ARGP_KEY_ARG') that they are not equipped to handle. -Standard Environment Variables ------------------------------- + A typical parser function uses a switch statement on KEY: - These environment variables have standard meanings.

Since the value in - the environment can be tweaked arbitrarily, this is not a reliable - way to identify the user who is running a program; a function like - `getlogin' (*note Who Logged In::) is better for that purpose. +Special Keys for Argp Parser Functions +...................................... - For most purposes, it is better to use `LOGNAME', precisely because - this lets the user specify the value. + In addition to key values corresponding to user options, the KEY +argument to argp parser functions may have a number of other special +values. In the following example ARG and STATE refer to parser +function arguments. *Note Argp Parser Functions::. -`PATH' - A "path" is a sequence of directory names which is used for - searching for a file. The variable `PATH' holds a path used for - searching for programs to be run. +`ARGP_KEY_ARG' + This is not an option at all, but rather a command line argument, + whose value is pointed to by ARG. - The `execlp' and `execvp' functions (*note Executing a File::) use - this environment variable, as do many shells and other utilities - which are implemented in terms of those functions. + When there are multiple parser functions in play due to argp + parsers being combined, it's impossible to know which one will + handle a specific argument. Each is called until one returns 0 or + an error other than `ARGP_ERR_UNKNOWN'; if an argument is not + handled, `argp_parse' immediately returns success, without parsing + any more arguments. - The syntax of a path is a sequence of directory names separated by - colons. An empty string instead of a directory name stands for the - current directory (*note Working Directory::). + Once a parser function returns success for this key, that fact is + recorded, and the `ARGP_KEY_NO_ARGS' case won't be used. + _However_, if while processing the argument a parser function + decrements the `next' field of its STATE argument, the option + won't be considered processed; this is to allow you to actually + modify the argument, perhaps into an option, and have it processed + again. - A typical value for this environment variable might be a string - like: +`ARGP_KEY_ARGS' + If a parser function returns `ARGP_ERR_UNKNOWN' for + `ARGP_KEY_ARG', it is immediately called again with the key + `ARGP_KEY_ARGS', which has a similar meaning, but is slightly more + convenient for consuming all remaining arguments. ARG is 0, and + the tail of the argument vector may be found at `STATE->argv + + STATE->next'. If success is returned for this key, and + `STATE->next' is unchanged, all remaining arguments are considered + to have been consumed. Otherwise, the amount by which + `STATE->next' has been adjusted indicates how many were used. + Here's an example that uses both, for different args: - :/bin:/etc:/usr/bin:/usr/new/X11:/usr/new:/usr/local/bin + ... + case ARGP_KEY_ARG: + if (STATE->arg_num == 0) + /* First argument */ + first_arg = ARG; + else + /* Let the next case parse it. */ + return ARGP_KEY_UNKNOWN; + break; + case ARGP_KEY_ARGS: + remaining_args = STATE->argv + STATE->next; + num_remaining_args = STATE->argc - STATE->next; + break; - This means that if the user tries to execute a program named `foo', - the system will look for files named `foo', `/bin/foo', - `/etc/foo', and so on. The first of these files that exists is - the one that is executed. +`ARGP_KEY_END' + This indicates that there are no more command line arguments. + Parser functions are called in a different order, children first. + This allows each parser to clean up its state for the parent. -`TERM' - This specifies the kind of terminal that is receiving program - output. Some programs can make use of this information to take - advantage of special escape sequences or terminal modes supported - by particular kinds of terminals. Many programs which use the - termcap library (*note Find: (termcap)Finding a Terminal - Description.) use the `TERM' environment variable, for example. +`ARGP_KEY_NO_ARGS' + Because it's common to do some special processing if there aren't + any non-option args, parser functions are called with this key if + they didn't successfully process any non-option arguments.

The service is generally something that only the kernel has -the privilege to do, such as doing I/O. Programmers don't normally -need to be concerned with system calls because there are functions in -the GNU C library to do virtually everything that system calls do. -These functions work by making system calls themselves. For example, -there is a system call that changes the permissions of a file, but you -don't need to know about it because you can just use the GNU C -library's `chmod' function. - - System calls are sometimes called kernel calls. - - However, there are times when you want to make a system call -explicitly, and for that, the GNU C library provides the `syscall' -function. `syscall' is harder to use and less portable than functions -like `chmod', but easier and more portable than coding the system call -in assembler instructions. - - `syscall' is most useful when you are working with a system call -which is special to your system or is newer than the GNU C library you -are using. `syscall' is implemented in an entirely generic way; the -function does not know anything about what a particular system call -does or even if it is valid. - - The description of `syscall' in this section assumes a certain -protocol for system calls on the various platforms on which the GNU C -library runs. That protocol is not defined by any strong authority, but -we won't describe it here either because anyone who is coding `syscall' -probably won't accept anything less than kernel and C library source -code as a specification of the interface between them anyway. - - `syscall' is declared in `unistd.h'. +File: libc.info, Node: Argp Helper Functions, Prev: Argp Parsing State, Up: Argp Parser Functions - - Function: long int syscall (long int SYSNO, ...) - `syscall' performs a generic system call. +Functions For Use in Argp Parsers +................................. - SYSNO is the system call number.

On other - systems, the value might be some other (possibly non-constant) - integer expression. + `int flags' + Flags for this child. - - Macro: int EXIT_FAILURE - This macro can be used with the `exit' function to indicate - unsuccessful program completion in a general sense. + `const char *header' + If non-zero, this is an optional header to be printed within + help output before the child options.

On other - systems, the value might be some other (possibly non-constant) - integer expression. Other nonzero status values also indicate - failures. Certain programs use different nonzero status values to - indicate particular kinds of "non-success". For example, `diff' - uses status value `1' to mean that the files are different, and - `2' or more to mean that there was difficulty in opening the files. + `int group' + This is where the child options are grouped relative to the + other `consolidated' options in the parent argp parser. The + values are the same as the `group' field in `struct + argp_option'. *Note Argp Option Vectors::. All + child-groupings follow parent options at a particular group + level. If both this field and `header' are zero, then the + child's options aren't grouped together, they are merged with + parent options at the parent option group level. - Don't confuse a program's exit status with a process' termination -status.

In the GNU C - library, it always uses the default shell `sh' to run the command. - In particular, it searches the directories in `PATH' to find - programs to execute. The return value is `-1' if it wasn't - possible to create the shell process, and otherwise is the status - of the shell process. *Note Process Completion::, for details on - how this status code can be interpreted. - - If the COMMAND argument is a null pointer, a return value of zero - indicates that no command processor is available. +File: libc.info, Node: Argp Help Flags, Up: Argp Help - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `system' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this calls to - `system' should be protected using cancellation handlers. +Flags for the `argp_help' Function +---------------------------------- - The `system' function is declared in the header file `stdlib.h'. + When calling `argp_help' (*note Argp Help::) or `argp_state_help' +(*note Argp Helper Functions::) the exact output is determined by the +FLAGS argument. This should consist of any of the following flags, +or'd together: - *Portability Note:* Some C implementations may not have any notion -of a command processor that can execute other programs. You can -determine whether a command processor exists by executing -`system (NULL)'; if the return value is nonzero, a command processor is -available. +`ARGP_HELP_USAGE' + A unix `Usage:' message that explicitly lists all options. - The `popen' and `pclose' functions (*note Pipe to a Subprocess::) -are closely related to the `system' function. They allow the parent -process to communicate with the standard input and output channels of -the command being executed. +`ARGP_HELP_SHORT_USAGE' + A unix `Usage:' message that displays an appropriate placeholder to + indicate where the options go; useful for showing the non-option + argument syntax. - -File: libc.info, Node: Process Creation Concepts, Next: Process Identification, Prev: Running a Command, Up: Processes +`ARGP_HELP_SEE' + A `Try ... for more help' message; `...' contains the program name + and `--help'. -Process Creation Concepts -========================= +`ARGP_HELP_LONG' + A verbose option help message that gives each option available + along with its documentation string. - This section gives an overview of processes and of the steps -involved in creating a process and making it run another program. +`ARGP_HELP_PRE_DOC' + The part of the argp parser doc string preceding the verbose + option help. - Each process is named by a "process ID" number. A unique process ID -is allocated to each process when it is created. The "lifetime" of a -process ends when its termination is reported to its parent process; at -that time, all of the process resources, including its process ID, are -freed. +`ARGP_HELP_POST_DOC' + The part of the argp parser doc string that following the verbose + option help. - Processes are created with the `fork' system call (so the operation -of creating a new process is sometimes called "forking" a process). -The "child process" created by `fork' is a copy of the original "parent -process", except that it has its own process ID. +`ARGP_HELP_DOC' + `(ARGP_HELP_PRE_DOC | ARGP_HELP_POST_DOC)' - After forking a child process, both the parent and child processes -continue to execute normally. If you want your program to wait for a -child process to finish executing before continuing, you must do this -explicitly after the fork operation, by calling `wait' or `waitpid' -(*note Process Completion::). These functions give you limited -information about why the child terminated--for example, its exit -status code. +`ARGP_HELP_BUG_ADDR' + A message that prints where to report bugs for this program, if the + `argp_program_bug_address' variable contains this information. - A newly forked child process continues to execute the same program as -its parent process, at the point where the `fork' call returns. You -can use the return value from `fork' to tell whether the program is -running in the parent process or the child. +`ARGP_HELP_LONG_ONLY' + This will modify any output to reflect the `ARGP_LONG_ONLY' mode. - Having several processes run the same program is only occasionally -useful. But the child can execute another program using one of the -`exec' functions; see *Note Executing a File::. The program that the -process is executing is called its "process image". Starting execution -of a new program causes the process to forget all about its previous -process image; when the new program exits, the process exits too, -instead of returning to the previous process image. + The following flags are only understood when used with +`argp_state_help'. They control whether the function returns after +printing its output, or terminates the program: - -File: libc.info, Node: Process Identification, Next: Creating a Process, Prev: Process Creation Concepts, Up: Processes +`ARGP_HELP_EXIT_ERR' + This will terminate the program with `exit (argp_err_exit_status)'. -Process Identification -====================== +`ARGP_HELP_EXIT_OK' + This will terminate the program with `exit (0)'. - The `pid_t' data type represents process IDs. You can get the -process ID of a process by calling `getpid'. The function `getppid' -returns the process ID of the parent of the current process (this is -also known as the "parent process ID"). Your program should include -the header files `unistd.h' and `sys/types.h' to use these functions. + The following flags are combinations of the basic flags for printing +standard messages: - - Data Type: pid_t - The `pid_t' data type is a signed integer type which is capable of - representing a process ID. In the GNU library, this is an `int'. +`ARGP_HELP_STD_ERR' + Assuming that an error message for a parsing error has printed, + this prints a message on how to get help, and terminates the + program with an error. - - Function: pid_t getpid (void) - The `getpid' function returns the process ID of the current - process. +`ARGP_HELP_STD_USAGE' + This prints a standard usage message and terminates the program + with an error. This is used when no other specific error messages + are appropriate or available. - - Function: pid_t getppid (void) - The `getppid' function returns the process ID of the parent of the - current process. +`ARGP_HELP_STD_HELP' + This prints the standard response for a `--help' option, and + terminates the program successfully.  -File: libc.info, Node: Creating a Process, Next: Executing a File, Prev: Process Identification, Up: Processes +File: libc.info, Node: Argp Examples, Next: Argp User Customization, Prev: Argp Help, Up: Argp -Creating a Process -================== +Argp Examples +------------- - The `fork' function is the primitive for creating a process.

Instead, the - child process created with `vfork' shares its parent's address - space until it calls `_exit' or one of the `exec' functions. In - the meantime, the parent process suspends execution. + This program uses the same features as example 2, adding user options +and arguments. - You must be very careful not to allow the child process created - with `vfork' to modify any global data or even local variables - shared with the parent. Furthermore, the child process cannot - return from (or do a long jump out of) the function that called - `vfork'! This would leave the parent process's control - information very confused. If in doubt, use `fork' instead. + We now use the first four fields in `argp' (*note Argp Parsers::) +and specify `parse_opt' as the parser function. *Note Argp Parser +Functions::. - Some operating systems don't really implement `vfork'. The GNU C - library permits you to use `vfork' on all systems, but actually - executes `fork' if `vfork' isn't available. If you follow the - proper precautions for using `vfork', your program will still work - even if the system uses `fork' instead. + Note that in this example, `main' uses a structure to communicate +with the `parse_opt' function, a pointer to which it passes in the +`input' argument to `argp_parse'. *Note Argp::.

All other signals are -set to the default action in the new process image. For more -information about signals, see *Note Signal Handling::. + When a program is executed, it receives information about the +context in which it was invoked in two ways. The first mechanism uses +the ARGV and ARGC arguments to its `main' function, and is discussed in +*Note Program Arguments::. The second mechanism uses "environment +variables" and is discussed in this section. - File descriptors open in the existing process image remain open in -the new process image, unless they have the `FD_CLOEXEC' -(close-on-exec) flag set. The files that remain open inherit all -attributes of the open file description from the existing process image, -including file locks. File descriptors are discussed in *Note -Low-Level I/O::. + The ARGV mechanism is typically used to pass command-line arguments +specific to the particular program being invoked. The environment, on +the other hand, keeps track of information that is shared by many +programs, changes infrequently, and that is less frequently used. - Streams, by contrast, cannot survive through `exec' functions, -because they are located in the memory of the process itself. The new -process image has no streams except those it creates afresh. Each of -the streams in the pre-`exec' process image has a descriptor inside it, -and these descriptors do survive through `exec' (provided that they do -not have `FD_CLOEXEC' set). The new process image can reconnect these -to new streams using `fdopen' (*note Descriptors and Streams::). + The environment variables discussed in this section are the same +environment variables that you set using assignments and the `export' +command in the shell. Programs executed from the shell inherit all of +the environment variables from the shell. + + Standard environment variables are used for information about the +user's home directory, terminal type, current locale, and so on; you +can define additional variables for other purposes. The set of all +environment variables that have values is collectively known as the +"environment". + + Names of environment variables are case-sensitive and must not +contain the character `='. System-defined environment variables are +invariably uppercase. + + The values of environment variables can be anything that can be +represented as a string. A value must not contain an embedded null +character, since this is assumed to terminate the string. + +* Menu: + +* Environment Access:: How to get and set the values of + environment variables. +* Standard Environment:: These environment variables have + standard interpretations.  -File: libc.info, Node: Process Completion, Next: Process Completion Status, Prev: Executing a File, Up: Processes +File: libc.info, Node: Environment Access, Next: Standard Environment, Up: Environment Variables -Process Completion -================== +Environment Access +------------------ - The functions described in this section are used to wait for a child -process to terminate or stop, and determine its status. These functions -are declared in the header file `sys/wait.h'. + The value of an environment variable can be accessed with the +`getenv' function. This is declared in the header file `stdlib.h'. +All of the following functions can be safely used in multi-threaded +programs. It is made sure that concurrent modifications to the +environment do not lead to errors. - - Function: pid_t waitpid (pid_t PID, int *STATUS-PTR, int OPTIONS) - The `waitpid' function is used to request status information from a - child process whose process ID is PID. Normally, the calling - process is suspended until the child process makes status - information available by terminating. + - Function: char * getenv (const char *NAME) + This function returns a string that is the value of the environment + variable NAME. You must not modify this string. In some non-Unix + systems not using the GNU library, it might be overwritten by + subsequent calls to `getenv' (but not by any other library + function). If the environment variable NAME is not defined, the + value is a null pointer. - Other values for the PID argument have special interpretations. A - value of `-1' or `WAIT_ANY' requests status information for any - child process; a value of `0' or `WAIT_MYPGRP' requests - information for any child process in the same process group as the - calling process; and any other negative value - PGID requests - information for any child process whose process group ID is PGID. + - Function: int putenv (char *STRING) + The `putenv' function adds or removes definitions from the + environment. If the STRING is of the form `NAME=VALUE', the + definition is added to the environment. Otherwise, the STRING is + interpreted as the name of an environment variable, and any + definition for this variable in the environment is removed. - If status information for a child process is available - immediately, this function returns immediately without waiting. - If more than one eligible child process has status information - available, one of them is chosen randomly, and its status is - returned immediately. To get the status from the other eligible - child processes, you need to call `waitpid' again. + The difference to the `setenv' function is that the exact string + given as the parameter STRING is put into the environment. If the + user should change the string after the `putenv' call this will + reflect in automatically in the environment. This also requires + that STRING is no automatic variable which scope is left before the + variable is removed from the environment. The same applies of + course to dynamically allocated variables which are freed later. - The OPTIONS argument is a bit mask. Its value should be the - bitwise OR (that is, the `|' operator) of zero or more of the - `WNOHANG' and `WUNTRACED' flags. You can use the `WNOHANG' flag - to indicate that the parent process shouldn't wait; and the - `WUNTRACED' flag to request status information from stopped - processes as well as processes that have terminated. + This function is part of the extended Unix interface. Since it + was also available in old SVID libraries you should define either + _XOPEN_SOURCE or _SVID_SOURCE before including any header. - The status information from the child process is stored in the - object that STATUS-PTR points to, unless STATUS-PTR is a null - pointer. + - Function: int setenv (const char *NAME, const char *VALUE, int + REPLACE) + The `setenv' function can be used to add a new definition to the + environment. The entry with the name NAME is replaced by the + value `NAME=VALUE'. Please note that this is also true if VALUE + is the empty string. To do this a new string is created and the + strings NAME and VALUE are copied. A null pointer for the VALUE + parameter is illegal. If the environment already contains an + entry with key NAME the REPLACE parameter controls the action. If + replace is zero, nothing happens. Otherwise the old entry is + replaced by the new one. - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `waitpid' is called. If the thread gets canceled these resources - stay allocated until the program ends. To avoid this calls to - `waitpid' should be protected using cancellation handlers. + Please note that you cannot remove an entry completely using this + function. - The return value is normally the process ID of the child process - whose status is reported. If there are child processes but none - of them is waiting to be noticed, `waitpid' will block until one - is. However, if the `WNOHANG' option was specified, `waitpid' - will return zero instead of blocking. + This function was originally part of the BSD library but is now + part of the Unix standard. - If a specific PID to wait for was given to `waitpid', it will - ignore all other children (if any). Therefore if there are - children waiting to be noticed but the child whose PID was - specified is not one of them, `waitpid' will block or return zero - as described above. + - Function: int unsetenv (const char *NAME) + Using this function one can remove an entry completely from the + environment. If the environment contains an entry with the key + NAME this whole entry is removed. A call to this function is + equivalent to a call to `putenv' when the VALUE part of the string + is empty. - A value of `-1' is returned in case of error. The following - `errno' error conditions are defined for this function: + The function return `-1' if NAME is a null pointer, points to an + empty string, or points to a string containing a `=' character. + It returns `0' if the call succeeded. - `EINTR' - The function was interrupted by delivery of a signal to the - calling process. *Note Interrupted Primitives::. + This function was originally part of the BSD library but is now + part of the Unix standard. The BSD version had no return value, + though. - `ECHILD' - There are no child processes to wait for, or the specified PID - is not a child of the calling process. + There is one more function to modify the whole environment. This +function is said to be used in the POSIX.9 (POSIX bindings for Fortran +77) and so one should expect it did made it into POSIX.1. But this +never happened. But we still provide this function as a GNU extension +to enable writing standard compliant Fortran environments. - `EINVAL' - An invalid value was provided for the OPTIONS argument. + - Function: int clearenv (void) + The `clearenv' function removes all entries from the environment. + Using `putenv' and `setenv' new entries can be added again later. - These symbolic constants are defined as values for the PID argument -to the `waitpid' function. + If the function is successful it returns `0'. Otherwise the return + value is nonzero. -`WAIT_ANY' - This constant macro (whose value is `-1') specifies that `waitpid' - should return status information about any child process. + You can deal directly with the underlying representation of +environment objects to add more variables to the environment (for +example, to communicate with another program you are about to execute; +*note Executing a File::). -`WAIT_MYPGRP' - This constant (with value `0') specifies that `waitpid' should - return status information about any child process in the same - process group as the calling process. + - Variable: char ** environ + The environment is represented as an array of strings. Each + string is of the format `NAME=VALUE'. The order in which strings + appear in the environment is not significant, but the same NAME + must not appear more than once. The last element of the array is + a null pointer. - These symbolic constants are defined as flags for the OPTIONS -argument to the `waitpid' function. You can bitwise-OR the flags -together to obtain a value to use as the argument. + This variable is declared in the header file `unistd.h'. -`WNOHANG' - This flag specifies that `waitpid' should return immediately - instead of waiting, if there is no child process ready to be - noticed. + If you just want to get the value of an environment variable, use + `getenv'. -`WUNTRACED' - This flag specifies that `waitpid' should report the status of any - child processes that have been stopped as well as those that have - terminated. + Unix systems, and the GNU system, pass the initial value of +`environ' as the third argument to `main'. *Note Program Arguments::. - - Function: pid_t wait (int *STATUS-PTR) - This is a simplified version of `waitpid', and is used to wait - until any one child process terminates. The call: + +File: libc.info, Node: Standard Environment, Prev: Environment Access, Up: Environment Variables - wait (&status) +Standard Environment Variables +------------------------------ - is exactly equivalent to: + These environment variables have standard meanings. This doesn't +mean that they are always present in the environment; but if these +variables _are_ present, they have these meanings. You shouldn't try +to use these environment variable names for some other purpose. - waitpid (-1, &status, 0) +`HOME' + This is a string representing the user's "home directory", or + initial default working directory. - This function is a cancellation point in multi-threaded programs. - This is a problem if the thread allocates some resources (like - memory, file descriptors, semaphores or whatever) at the time - `wait' is called.

To avoid this calls to - `wait' should be protected using cancellation handlers. + The user can set `HOME' to any value. If you need to make sure to + obtain the proper home directory for a particular user, you should + not use `HOME'; instead, look up the user's name in the user + database (*note User Database::). - - Function: pid_t wait4 (pid_t PID, int *STATUS-PTR, int OPTIONS, - struct rusage *USAGE) - If USAGE is a null pointer, `wait4' is equivalent to `waitpid - (PID, STATUS-PTR, OPTIONS)'. + For most purposes, it is better to use `HOME', precisely because + this lets the user specify the value. - If USAGE is not null, `wait4' stores usage figures for the child - process in `*RUSAGE' (but only if the child has terminated, not if - it has stopped). *Note Resource Usage::. +`LOGNAME' + This is the name that the user used to log in.

The service is generally something that only the kernel has +the privilege to do, such as doing I/O. Programmers don't normally +need to be concerned with system calls because there are functions in +the GNU C library to do virtually everything that system calls do. +These functions work by making system calls themselves. For example, +there is a system call that changes the permissions of a file, but you +don't need to know about it because you can just use the GNU C +library's `chmod' function. - Instead of accessing these members directly, you should use the - equivalent macros. + System calls are sometimes called kernel calls. - The `wait3' function is the predecessor to `wait4', which is more -flexible. `wait3' is now obsolete. + However, there are times when you want to make a system call +explicitly, and for that, the GNU C library provides the `syscall' +function. `syscall' is harder to use and less portable than functions +like `chmod', but easier and more portable than coding the system call +in assembler instructions. - - Function: pid_t wait3 (union wait *STATUS-PTR, int OPTIONS, struct - rusage *USAGE) - If USAGE is a null pointer, `wait3' is equivalent to `waitpid (-1, - STATUS-PTR, OPTIONS)'. + `syscall' is most useful when you are working with a system call +which is special to your system or is newer than the GNU C library you +are using. `syscall' is implemented in an entirely generic way; the +function does not know anything about what a particular system call +does or even if it is valid. - If USAGE is not null, `wait3' stores usage figures for the child - process in `*RUSAGE' (but only if the child has terminated, not if - it has stopped). *Note Resource Usage::. + The description of `syscall' in this section assumes a certain +protocol for system calls on the various platforms on which the GNU C +library runs. That protocol is not defined by any strong authority, but +we won't describe it here either because anyone who is coding `syscall' +probably won't accept anything less than kernel and C library source +code as a specification of the interface between them anyway. - -File: libc.info, Node: Process Creation Example, Prev: BSD Wait Functions, Up: Processes + `syscall' is declared in `unistd.h'. -Process Creation Example -======================== + - Function: long int syscall (long int SYSNO, ...) + `syscall' performs a generic system call. - Here is an example program showing how you might write a function -similar to the built-in `system'.

Macros for all the possible system call + numbers are defined in `sys/syscall.h' - #include - #include - #include - #include - #include - - /* Execute the command using this shell program. */ - #define SHELL "/bin/sh" - - int - my_system (const char *command) - { - int status; - pid_t pid; - - pid = fork (); - if (pid == 0) - { - /* This is the child process. Execute the shell command. */ - execl (SHELL, SHELL, "-c", command, NULL); - _exit (EXIT_FAILURE); - } - else if (pid < 0) - /* The fork failed. Report failure. */ - status = -1; - else - /* This is the parent process. Wait for the child to complete. */ - if (waitpid (pid, &status, 0) != pid) - status = -1; - return status; - } + The remaining arguments are the arguments for the system call, in + order, and their meanings depend on the kind of system call. Each + kind of system call has a definite number of arguments, from zero + to five. If you code more arguments than the system call takes, + the extra ones to the right are ignored. - There are a couple of things you should pay attention to in this -example. + The return value is the return value from the system call, unless + the system call failed. In that case, `syscall' returns `-1' and + sets `errno' to an error code that the system call returned. Note + that system calls do not return `-1' when they succeed. - Remember that the first `argv' argument supplied to the program -represents the name of the program being executed. That is why, in the -call to `execl', `SHELL' is supplied once to name the program to -execute and a second time to supply a value for `argv[0]'. + If you specify an invalid SYSNO, `syscall' returns `-1' with + `errno' = `ENOSYS'. - The `execl' call in the child process doesn't return if it is -successful. If it fails, you must do something to make the child -process terminate. Just returning a bad status code with `return' -would leave two processes running the original program. Instead, the -right behavior is for the child process to report failure to its parent -process. + Example: + + + #include + #include + #include + + ... + + int rc; + + rc = syscall(SYS_chmod, "/etc/passwd", 0444); + + if (rc == -1) + fprintf(stderr, "chmod failed, errno = %d\n", errno); + + This, if all the compatibility stars are aligned, is equivalent to + the following preferable code: + + + #include + #include + #include + + ... + + int rc; + + rc = chmod("/etc/passwd", 0444); + if (rc == -1) + fprintf(stderr, "chmod failed, errno = %d\n", errno); - Call `_exit' to accomplish this. The reason for using `_exit' -instead of `exit' is to avoid flushing fully buffered streams such as -`stdout'. The buffers of these streams probably contain data that was -copied from the parent process by the `fork', data that will be output -eventually by the parent process. Calling `exit' in the child would -output the data twice. *Note Termination Internals::.  -File: libc.info, Node: Job Control, Next: Name Service Switch, Prev: Processes, Up: Top +File: libc.info, Node: Program Termination, Prev: System Calls, Up: Program Basics -Job Control -*********** +Program Termination +=================== - "Job control" refers to the protocol for allowing a user to move -between multiple "process groups" (or "jobs") within a single "login -session". The job control facilities are set up so that appropriate -behavior for most programs happens automatically and they need not do -anything special about job control. So you can probably ignore the -material in this chapter unless you are writing a shell or login -program. + The usual way for a program to terminate is simply for its `main' +function to return. The "exit status value" returned from the `main' +function is used to report information back to the process's parent +process or shell. - You need to be familiar with concepts relating to process creation -(*note Process Creation Concepts::) and signal handling (*note Signal -Handling::) in order to understand this material presented in this -chapter. + A program can also terminate normally by calling the `exit' function. + + In addition, programs can be terminated by signals; this is +discussed in more detail in *Note Signal Handling::.

It can do this using the `fork' (*note -Creating a Process::) and `exec' (*note Executing a File::) functions. + A process terminates normally when its program signals it is done by +calling `exit'. Returning from `main' is equivalent to calling `exit', +and the value that `main' returns is used as the argument to `exit'. - A single command may run just one process--but often one command uses -several processes. If you use the `|' operator in a shell command, you -explicitly request several programs in their own processes. But even -if you run just one program, it can use multiple processes internally. -For example, a single compilation command such as `cc -c foo.c' -typically uses four processes (though normally only two at any given -time). If you run `make', its job is to run other programs in separate -processes. + - Function: void exit (int STATUS) + The `exit' function tells the system that the program is done, + which causes it to terminate the process. - The processes belonging to a single command are called a "process -group" or "job". This is so that you can operate on all of them at -once. For example, typing `C-c' sends the signal `SIGINT' to terminate -all the processes in the foreground process group. + STATUS is the program's exit status, which becomes part of the + process' termination status. This function does not return. - A "session" is a larger group of processes. Normally all the -processes that stem from a single login belong to the same session. + Normal termination causes the following actions: - Every process belongs to a process group. When a process is -created, it becomes a member of the same process group and session as -its parent process. You can put it in another process group using the -`setpgid' function, provided the process group belongs to the same -session. + 1. Functions that were registered with the `atexit' or `on_exit' + functions are called in the reverse order of their registration. + This mechanism allows your application to specify its own + "cleanup" actions to be performed at program termination. + Typically, this is used to do things like saving program state + information in a file, or unlocking locks in shared data bases. - The only way to put a process in a different session is to make it -the initial process of a new session, or a "session leader", using the -`setsid' function. This also puts the session leader into a new -process group, and you can't move it out of that process group again. + 2. All open streams are closed, writing out any buffered output data. + See *Note Closing Streams::. In addition, temporary files opened + with the `tmpfile' function are removed; see *Note Temporary + Files::. - Usually, new sessions are created by the system login program, and -the session leader is the process running the user's login shell. + 3. `_exit' is called, terminating the program. *Note Termination + Internals::. - A shell that supports job control must arrange to control which job -can use the terminal at any time. Otherwise there might be multiple -jobs trying to read from the terminal at once, and confusion about which -process should receive the input typed by the user. To prevent this, -the shell must cooperate with the terminal driver using the protocol -described in this chapter. + +File: libc.info, Node: Exit Status, Next: Cleanups on Exit, Prev: Normal Termination, Up: Program Termination - The shell can give unlimited access to the controlling terminal to -only one process group at a time. This is called the "foreground job" -on that controlling terminal. Other process groups managed by the shell -that are executing without such access to the terminal are called -"background jobs". +Exit Status +----------- - If a background job needs to read from its controlling terminal, it -is "stopped" by the terminal driver; if the `TOSTOP' mode is set, -likewise for writing. The user can stop a foreground job by typing the -SUSP character (*note Special Characters::) and a program can stop any -job by sending it a `SIGSTOP' signal. It's the responsibility of the -shell to notice when jobs stop, to notify the user about them, and to -provide mechanisms for allowing the user to interactively continue -stopped jobs and switch jobs between foreground and background. + When a program exits, it can return to the parent process a small +amount of information about the cause of termination, using the "exit +status". This is a value between 0 and 255 that the exiting process +passes as an argument to `exit'. - *Note Access to the Terminal::, for more information about I/O to the -controlling terminal, + Normally you should use the exit status to report very broad +information about success or failure. You can't provide a lot of +detail about the reasons for the failure, and most parent processes +would not want much detail anyway. + + There are conventions for what sorts of status values certain +programs should return. The most common convention is simply 0 for +success and 1 for failure. Programs that perform comparison use a +different convention: they use status 1 to indicate a mismatch, and +status 2 to indicate an inability to compare. Your program should +follow an existing convention if an existing convention makes sense for +it. + + A general convention reserves status values 128 and up for special +purposes. In particular, the value 128 is used to indicate failure to +execute another program in a subprocess. This convention is not +universally obeyed, but it is a good idea to follow it in your programs. + + *Warning:* Don't try to use the number of errors as the exit status. +This is actually not very useful; a parent process would generally not +care how many errors occurred. Worse than that, it does not work, +because the status value is truncated to eight bits. Thus, if the +program tried to report 256 errors, the parent would receive a report +of 0 errors--that is, success. + + For the same reason, it does not work to use the value of `errno' as +the exit status--these can exceed 255. + + *Portability note:* Some non-POSIX systems use different conventions +for exit status values. For greater portability, you can use the +macros `EXIT_SUCCESS' and `EXIT_FAILURE' for the conventional status +value for success and failure, respectively. They are declared in the +file `stdlib.h'. + + - Macro: int EXIT_SUCCESS + This macro can be used with the `exit' function to indicate + successful program completion. + + On POSIX systems, the value of this macro is `0'. On other + systems, the value might be some other (possibly non-constant) + integer expression. + + - Macro: int EXIT_FAILURE + This macro can be used with the `exit' function to indicate + unsuccessful program completion in a general sense. + + On POSIX systems, the value of this macro is `1'. On other + systems, the value might be some other (possibly non-constant) + integer expression. Other nonzero status values also indicate + failures. Certain programs use different nonzero status values to + indicate particular kinds of "non-success". For example, `diff' + uses status value `1' to mean that the files are different, and + `2' or more to mean that there was difficulty in opening the files. + + Don't confuse a program's exit status with a process' termination +status. There are lots of ways a process can terminate besides having +it's program finish. In the event that the process termination _is_ +caused by program termination (i.e. `exit'), though, the program's exit +status becomes part of the process' termination status.  -File: libc.info, Node: Job Control is Optional, Next: Controlling Terminal, Prev: Concepts of Job Control, Up: Job Control +File: libc.info, Node: Cleanups on Exit, Next: Aborting a Program, Prev: Exit Status, Up: Program Termination -Job Control is Optional -======================= +Cleanups on Exit +---------------- - Not all operating systems support job control.

They allow the parent +process to communicate with the standard input and output channels of +the command being executed. - When a shell program that normally performs job control is started, -it has to be careful in case it has been invoked from another shell -that is already doing its own job control. + +File: libc.info, Node: Process Creation Concepts, Next: Process Identification, Prev: Running a Command, Up: Processes - A subshell that runs interactively has to ensure that it has been -placed in the foreground by its parent shell before it can enable job -control itself. It does this by getting its initial process group ID -with the `getpgrp' function, and comparing it to the process group ID -of the current foreground job associated with its controlling terminal -(which can be retrieved using the `tcgetpgrp' function). +Process Creation Concepts +========================= - If the subshell is not running as a foreground job, it must stop -itself by sending a `SIGTTIN' signal to its own process group. It may -not arbitrarily put itself into the foreground; it must wait for the -user to tell the parent shell to do this. If the subshell is continued -again, it should repeat the check and stop itself again if it is still -not in the foreground. + This section gives an overview of processes and of the steps +involved in creating a process and making it run another program. - Once the subshell has been placed into the foreground by its parent -shell, it can enable its own job control. It does this by calling -`setpgid' to put itself into its own process group, and then calling -`tcsetpgrp' to place this process group into the foreground. + Each process is named by a "process ID" number. A unique process ID +is allocated to each process when it is created. The "lifetime" of a +process ends when its termination is reported to its parent process; at +that time, all of the process resources, including its process ID, are +freed. - When a shell enables job control, it should set itself to ignore all -the job control stop signals so that it doesn't accidentally stop -itself. You can do this by setting the action for all the stop signals -to `SIG_IGN'. + Processes are created with the `fork' system call (so the operation +of creating a new process is sometimes called "forking" a process). +The "child process" created by `fork' is a copy of the original "parent +process", except that it has its own process ID. - A subshell that runs non-interactively cannot and should not support -job control. It must leave all processes it creates in the same process -group as the shell itself; this allows the non-interactive shell and its -child processes to be treated as a single job by the parent shell. This -is easy to do--just don't use any of the job control primitives--but -you must remember to make the shell do it. + After forking a child process, both the parent and child processes +continue to execute normally. If you want your program to wait for a +child process to finish executing before continuing, you must do this +explicitly after the fork operation, by calling `wait' or `waitpid' +(*note Process Completion::). These functions give you limited +information about why the child terminated--for example, its exit +status code. - Here is the initialization code for the sample shell that shows how -to do all of this. + A newly forked child process continues to execute the same program as +its parent process, at the point where the `fork' call returns. You +can use the return value from `fork' to tell whether the program is +running in the parent process or the child. - /* Keep track of attributes of the shell. */ - - #include - #include - #include - - pid_t shell_pgid; - struct termios shell_tmodes; - int shell_terminal; - int shell_is_interactive; - - - /* Make sure the shell is running interactively as the foreground job - before proceeding. */ - - void - init_shell () - { - - /* See if we are running interactively. */ - shell_terminal = STDIN_FILENO; - shell_is_interactive = isatty (shell_terminal); - - if (shell_is_interactive) - { - /* Loop until we are in the foreground. */ - while (tcgetpgrp (shell_terminal) != (shell_pgid = getpgrp ())) - kill (- shell_pgid, SIGTTIN); - - /* Ignore interactive and job-control signals. */ - signal (SIGINT, SIG_IGN); - signal (SIGQUIT, SIG_IGN); - signal (SIGTSTP, SIG_IGN); - signal (SIGTTIN, SIG_IGN); - signal (SIGTTOU, SIG_IGN); - signal (SIGCHLD, SIG_IGN); - - /* Put ourselves in our own process group. */ - shell_pgid = getpid (); - if (setpgid (shell_pgid, shell_pgid) < 0) - { - perror ("Couldn't put the shell in its own process group"); - exit (1); - } - - /* Grab control of the terminal. */ - tcsetpgrp (shell_terminal, shell_pgid); - - /* Save default terminal attributes for shell. */ - tcgetattr (shell_terminal, &shell_tmodes); - } - } + Having several processes run the same program is only occasionally +useful. But the child can execute another program using one of the +`exec' functions; see *Note Executing a File::. The program that the +process is executing is called its "process image". Starting execution +of a new program causes the process to forget all about its previous +process image; when the new program exits, the process exits too, +instead of returning to the previous process image.  -File: libc.info, Node: Launching Jobs, Next: Foreground and Background, Prev: Initializing the Shell, Up: Implementing a Shell - -Launching Jobs --------------- - - Once the shell has taken responsibility for performing job control on -its controlling terminal, it can launch jobs in response to commands -typed by the user. +File: libc.info, Node: Process Identification, Next: Creating a Process, Prev: Process Creation Concepts, Up: Processes - To create the processes in a process group, you use the same `fork' -and `exec' functions described in *Note Process Creation Concepts::. -Since there are multiple child processes involved, though, things are a -little more complicated and you must be careful to do things in the -right order. Otherwise, nasty race conditions can result. +Process Identification +====================== - You have two choices for how to structure the tree of parent-child -relationships among the processes. You can either make all the -processes in the process group be children of the shell process, or you -can make one process in group be the ancestor of all the other processes -in that group. The sample shell program presented in this chapter uses -the first approach because it makes bookkeeping somewhat simpler. + The `pid_t' data type represents process IDs. You can get the +process ID of a process by calling `getpid'. The function `getppid' +returns the process ID of the parent of the current process (this is +also known as the "parent process ID"). Your program should include +the header files `unistd.h' and `sys/types.h' to use these functions. - As each process is forked, it should put itself in the new process -group by calling `setpgid'; see *Note Process Group Functions::. The -first process in the new group becomes its "process group leader", and -its process ID becomes the "process group ID" for the group. + - Data Type: pid_t + The `pid_t' data type is a signed integer type which is capable of + representing a process ID. In the GNU library, this is an `int'. - The shell should also call `setpgid' to put each of its child -processes into the new process group. This is because there is a -potential timing problem: each child process must be put in the process -group before it begins executing a new program, and the shell depends on -having all the child processes in the group before it continues -executing. If both the child processes and the shell call `setpgid', -this ensures that the right things happen no matter which process gets -to it first. + - Function: pid_t getpid (void) + The `getpid' function returns the process ID of the current + process. - If the job is being launched as a foreground job, the new process -group also needs to be put into the foreground on the controlling -terminal using `tcsetpgrp'. Again, this should be done by the shell as -well as by each of its child processes, to avoid race conditions. + - Function: pid_t getppid (void) + The `getppid' function returns the process ID of the parent of the + current process. - The next thing each child process should do is to reset its signal -actions. + +File: libc.info, Node: Creating a Process, Next: Executing a File, Prev: Process Identification, Up: Processes - During initialization, the shell process set itself to ignore job -control signals; see *Note Initializing the Shell::. As a result, any -child processes it creates also ignore these signals by inheritance. -This is definitely undesirable, so each child process should explicitly -set the actions for these signals back to `SIG_DFL' just after it is -forked. +Creating a Process +================== - Since shells follow this convention, applications can assume that -they inherit the correct handling of these signals from the parent -process. But every application has a responsibility not to mess up the -handling of stop signals. Applications that disable the normal -interpretation of the SUSP character should provide some other -mechanism for the user to stop the job. When the user invokes this -mechanism, the program should send a `SIGTSTP' signal to the process -group of the process, not just to the process itself. *Note Signaling -Another Process::. + The `fork' function is the primitive for creating a process. It is +declared in the header file `unistd.h'. - Finally, each child process should call `exec' in the normal way. -This is also the point at which redirection of the standard input and -output channels should be handled. *Note Duplicating Descriptors::, -for an explanation of how to do this. + - Function: pid_t fork (void) + The `fork' function creates a new process. - Here is the function from the sample shell program that is -responsible for launching a program.

This does not mean these services are -available on all sites and it does also not mean these are all the -services which will ever be available. + Remember that the first `argv' argument supplied to the program +represents the name of the program being executed. That is why, in the +call to `execl', `SHELL' is supplied once to name the program to +execute and a second time to supply a value for `argv[0]'. - In fact, these names are simply strings which the NSS code uses to -find the implicitly addressed functions. The internal interface will be -described later. Visible to the user are the modules which implement an -individual service. + The `execl' call in the child process doesn't return if it is +successful. If it fails, you must do something to make the child +process terminate. Just returning a bad status code with `return' +would leave two processes running the original program. Instead, the +right behavior is for the child process to report failure to its parent +process. - Assume the service NAME shall be used for a lookup. The code for -this service is implemented in a module called `libnss_NAME'. On a -system supporting shared libraries this is in fact a shared library -with the name (for example) `libnss_NAME.so.2'.

The reason for using `_exit' +instead of `exit' is to avoid flushing fully buffered streams such as +`stdout'. The buffers of these streams probably contain data that was +copied from the parent process by the `fork', data that will be output +eventually by the parent process.

This can either mean the - needed file is not available, or, for DNS, the server is not - available or does not allow queries. The default action is - `continue'. + The fundamental purpose of an interactive shell is to read commands +from the user's terminal and create processes to execute the programs +specified by those commands. It can do this using the `fork' (*note +Creating a Process::) and `exec' (*note Executing a File::) functions. -`tryagain' - The service is temporarily unavailable. This could mean a file is - locked or a server currently cannot accept more connections. The - default action is `continue'. + A single command may run just one process--but often one command uses +several processes. If you use the `|' operator in a shell command, you +explicitly request several programs in their own processes. But even +if you run just one program, it can use multiple processes internally. +For example, a single compilation command such as `cc -c foo.c' +typically uses four processes (though normally only two at any given +time). If you run `make', its job is to run other programs in separate +processes. -If we have a line like + The processes belonging to a single command are called a "process +group" or "job". This is so that you can operate on all of them at +once. For example, typing `C-c' sends the signal `SIGINT' to terminate +all the processes in the foreground process group. - ethers: nisplus [NOTFOUND=return] db files + A "session" is a larger group of processes. Normally all the +processes that stem from a single login belong to the same session. -this is equivalent to + Every process belongs to a process group. When a process is +created, it becomes a member of the same process group and session as +its parent process. You can put it in another process group using the +`setpgid' function, provided the process group belongs to the same +session. - ethers: nisplus [SUCCESS=return NOTFOUND=return UNAVAIL=continue - TRYAGAIN=continue] - db [SUCCESS=return NOTFOUND=continue UNAVAIL=continue - TRYAGAIN=continue] - files + The only way to put a process in a different session is to make it +the initial process of a new session, or a "session leader", using the +`setsid' function. This also puts the session leader into a new +process group, and you can't move it out of that process group again. -(except that it would have to be written on one line). The default -value for the actions are normally what you want, and only need to be -changed in exceptional cases. + Usually, new sessions are created by the system login program, and +the session leader is the process running the user's login shell. - If the optional `!' is placed before the STATUS this means the -following action is used for all statuses but STATUS itself. I.e., `!' -is negation as in the C language (and others). + A shell that supports job control must arrange to control which job +can use the terminal at any time. Otherwise there might be multiple +jobs trying to read from the terminal at once, and confusion about which +process should receive the input typed by the user. To prevent this, +the shell must cooperate with the terminal driver using the protocol +described in this chapter. - Before we explain the exception which makes this action item -necessary one more remark: obviously it makes no sense to add another -action item after the `files' service. Since there is no other service -following the action _always_ is `return'. + The shell can give unlimited access to the controlling terminal to +only one process group at a time. This is called the "foreground job" +on that controlling terminal. Other process groups managed by the shell +that are executing without such access to the terminal are called +"background jobs". - Now, why is this `[NOTFOUND=return]' action useful? To understand -this we should know that the `nisplus' service is often complete; i.e., -if an entry is not available in the NIS+ tables it is not available -anywhere else. This is what is expressed by this action item: it is -useless to examine further services since they will not give us a -result. + If a background job needs to read from its controlling terminal, it +is "stopped" by the terminal driver; if the `TOSTOP' mode is set, +likewise for writing. The user can stop a foreground job by typing the +SUSP character (*note Special Characters::) and a program can stop any +job by sending it a `SIGSTOP' signal. It's the responsibility of the +shell to notice when jobs stop, to notify the user about them, and to +provide mechanisms for allowing the user to interactively continue +stopped jobs and switch jobs between foreground and background. - The situation would be different if the NIS+ service is not available -because the machine is booting. In this case the return value of the -lookup function is not `notfound' but instead `unavail'. And as you -can see in the complete form above: in this situation the `db' and -`files' services are used. Neat, isn't it? The system administrator -need not pay special care for the time the system is not completely -ready to work (while booting or shutdown or network problems). + *Note Access to the Terminal::, for more information about I/O to the +controlling terminal,  -File: libc.info, Node: Notes on NSS Configuration File, Prev: Actions in the NSS configuration, Up: NSS Configuration File - -Notes on the NSS Configuration File ------------------------------------ - - Finally a few more hints. The NSS implementation is not completely -helpless if `/etc/nsswitch.conf' does not exist. For all supported -databases there is a default value so it should normally be possible to -get the system running even if the file is corrupted or missing. +File: libc.info, Node: Job Control is Optional, Next: Controlling Terminal, Prev: Concepts of Job Control, Up: Job Control - For the `hosts' and `networks' databases the default value is `dns -[!UNAVAIL=return] files'. I.e., the system is prepared for the DNS -service not to be available but if it is available the answer it -returns is definitive. +Job Control is Optional +======================= - The `passwd', `group', and `shadow' databases are traditionally -handled in a special way. The appropriate files in the `/etc' -directory are read but if an entry with a name starting with a `+' -character is found NIS is used. This kind of lookup remains possible -by using the special lookup service `compat' and the default value for -the three databases above is `compat [NOTFOUND=return] files'. + Not all operating systems support job control. The GNU system does +support job control, but if you are using the GNU library on some other +system, that system may not support job control itself. - For all other databases the default value is `nis [NOTFOUND=return] -files'. This solution give the best chance to be correct since NIS and -file based lookup is used. + You can use the `_POSIX_JOB_CONTROL' macro to test at compile-time +whether the system supports job control. *Note System Options::. - A second point is that the user should try to optimize the lookup -process. The different service have different response times. A -simple file look up on a local file could be fast, but if the file is -long and the needed entry is near the end of the file this may take -quite some time. In this case it might be better to use the `db' -service which allows fast local access to large data sets. + If job control is not supported, then there can be only one process +group per session, which behaves as if it were always in the foreground. +The functions for creating additional process groups simply fail with +the error code `ENOSYS'. - Often the situation is that some global information like NIS must be -used. So it is unavoidable to use service entries like `nis' etc. But -one should avoid slow services like this if possible. + The macros naming the various job control signals (*note Job Control +Signals::) are defined even if job control is not supported. However, +the system never generates these signals, and attempts to send a job +control signal or examine or specify their actions report errors or do +nothing.  -File: libc.info, Node: NSS Module Internals, Next: Extending NSS, Prev: NSS Configuration File, Up: Name Service Switch +File: libc.info, Node: Controlling Terminal, Next: Access to the Terminal, Prev: Job Control is Optional, Up: Job Control -NSS Module Internals -==================== +Controlling Terminal of a Process +================================= - Now it is time to describe what the modules look like. The functions -contained in a module are identified by their names. I.e., there is no -jump table or the like. How this is done is of no interest here; those -interested in this topic should read about Dynamic Linking. + One of the attributes of a process is its controlling terminal. +Child processes created with `fork' inherit the controlling terminal +from their parent process. In this way, all the processes in a session +inherit the controlling terminal from the session leader. A session +leader that has control of a terminal is called the "controlling +process" of that terminal. -* Menu: + You generally do not need to worry about the exact mechanism used to +allocate a controlling terminal to a session, since it is done for you +by the system when you log in. -* NSS Module Names:: Construction of the interface function of - the NSS modules. -* NSS Modules Interface:: Programming interface in the NSS module - functions. + An individual process disconnects from its controlling terminal when +it calls `setsid' to become the leader of a new session. *Note Process +Group Functions::.  -File: libc.info, Node: NSS Module Names, Next: NSS Modules Interface, Prev: NSS Module Internals, Up: NSS Module Internals - -The Naming Scheme of the NSS Modules ------------------------------------- - -The name of each function consist of various parts: - - _nss_SERVICE_FUNCTION - - SERVICE of course corresponds to the name of the module this -function is found in.(1) The FUNCTION part is derived from the -interface function in the C library itself. If the user calls the -function `gethostbyname' and the service used is `files' the function - - _nss_files_gethostbyname_r - -in the module - - libnss_files.so.2 - -is used. You see, what is explained above in not the whole truth. In -fact the NSS modules only contain reentrant versions of the lookup -functions. I.e., if the user would call the `gethostbyname_r' function -this also would end in the above function. For all user interface -functions the C library maps this call to a call to the reentrant -function. For reentrant functions this is trivial since the interface -is (nearly) the same. For the non-reentrant version The library keeps -internal buffers which are used to replace the user supplied buffer. +File: libc.info, Node: Access to the Terminal, Next: Orphaned Process Groups, Prev: Controlling Terminal, Up: Job Control - I.e., the reentrant functions _can_ have counterparts. No service -module is forced to have functions for all databases and all kinds to -access them. If a function is not available it is simply treated as if -the function would return `unavail' (*note Actions in the NSS -configuration::). +Access to the Controlling Terminal +================================== - The file name `libnss_files.so.2' would be on a Solaris 2 system -`nss_files.so.2'. This is the difference mentioned above. Sun's NSS -modules are usable as modules which get indirectly loaded only. + Processes in the foreground job of a controlling terminal have +unrestricted access to that terminal; background processes do not. This +section describes in more detail what happens when a process in a +background job tries to access its controlling terminal. - The NSS modules in the GNU C Library are prepared to be used as -normal libraries themselves. This is _not_ true at the moment, though. -However, the organization of the name space in the modules does not -make it impossible like it is for Solaris. Now you can see why the -modules are still libraries.(2) + When a process in a background job tries to read from its controlling +terminal, the process group is usually sent a `SIGTTIN' signal. This +normally causes all of the processes in that group to stop (unless they +handle the signal and don't stop themselves). However, if the reading +process is ignoring or blocking this signal, then `read' fails with an +`EIO' error instead. - ---------- Footnotes ---------- + Similarly, when a process in a background job tries to write to its +controlling terminal, the default behavior is to send a `SIGTTOU' +signal to the process group. However, the behavior is modified by the +`TOSTOP' bit of the local modes flags (*note Local Modes::). If this +bit is not set (which is the default), then writing to the controlling +terminal is always permitted without sending a signal. Writing is also +permitted if the `SIGTTOU' signal is being ignored or blocked by the +writing process. - (1) Now you might ask why this information is duplicated. The -answer is that we want to make it possible to link directly with these -shared objects. + Most other terminal operations that a program can do are treated as +reading or as writing. (The description of each operation should say +which.) - (2) There is a second explanation: we were too lazy to change the -Makefiles to allow the generation of shared objects not starting with -`lib' but don't tell this to anybody. + For more information about the primitive `read' and `write' +functions, see *Note I/O Primitives::.  -File: libc.info, Node: NSS Modules Interface, Prev: NSS Module Names, Up: NSS Module Internals - -The Interface of the Function in NSS Modules --------------------------------------------- - - Now we know about the functions contained in the modules. It is now -time to describe the types. When we mentioned the reentrant versions of -the functions above, this means there are some additional arguments -(compared with the standard, non-reentrant version). The prototypes for -the non-reentrant and reentrant versions of our function above are: - - struct hostent *gethostbyname (const char *name) - - int gethostbyname_r (const char *name, struct hostent *result_buf, - char *buf, size_t buflen, struct hostent **result, - int *h_errnop) - -The actual prototype of the function in the NSS modules in this case is - - enum nss_status _nss_files_gethostbyname_r (const char *name, - struct hostent *result_buf, - char *buf, size_t buflen, - int *errnop, int *h_errnop) - - I.e., the interface function is in fact the reentrant function with -the change of the return value and the omission of the RESULT -parameter. While the user-level function returns a pointer to the -result the reentrant function return an `enum nss_status' value: - -`NSS_STATUS_TRYAGAIN' - numeric value `-2' - -`NSS_STATUS_UNAVAIL' - numeric value `-1' - -`NSS_STATUS_NOTFOUND' - numeric value `0' - -`NSS_STATUS_SUCCESS' - numeric value `1' - -Now you see where the action items of the `/etc/nsswitch.conf' file are -used. - - If you study the source code you will find there is a fifth value: -`NSS_STATUS_RETURN'. This is an internal use only value, used by a few -functions in places where none of the above value can be used. If -necessary the source code should be examined to learn about the details. - - In case the interface function has to return an error it is important -that the correct error code is stored in `*ERRNOP'. Some return status -value have only one associated error code, others have more. - -`NSS_STATUS_TRYAGAIN' `EAGAIN' One of the functions used ran - temporarily out of resources or a - service is currently not available. - `ERANGE' The provided buffer is not large - enough. The function should be - called again with a larger buffer. -`NSS_STATUS_UNAVAIL' `ENOENT' A necessary input file cannot be - found. -`NSS_STATUS_NOTFOUND' `ENOENT' The requested entry is not - available. - - These are proposed values. There can be other error codes and the -described error codes can have different meaning. *With one -exception:* when returning `NSS_STATUS_TRYAGAIN' the error code -`ERANGE' _must_ mean that the user provided buffer is too small. -Everything is non-critical. - - The above function has something special which is missing for almost -all the other module functions. There is an argument H_ERRNOP. This -points to a variable which will be filled with the error code in case -the execution of the function fails for some reason. The reentrant -function cannot use the global variable H_ERRNO; `gethostbyname' calls -`gethostbyname_r' with the last argument set to `&h_errno'. - - The `getXXXbyYYY' functions are the most important functions in the -NSS modules. But there are others which implement the other ways to -access system databases (say for the password database, there are -`setpwent', `getpwent', and `endpwent'). These will be described in -more detail later. Here we give a general way to determine the -signature of the module function: - - * the return value is `int'; - - * the name is as explained in *note NSS Module Names::; - - * the first arguments are identical to the arguments of the - non-reentrant function; - - * the next three arguments are: - - `STRUCT_TYPE *result_buf' - pointer to buffer where the result is stored. `STRUCT_TYPE' - is normally a struct which corresponds to the database. +File: libc.info, Node: Orphaned Process Groups, Next: Implementing a Shell, Prev: Access to the Terminal, Up: Job Control - `char *buffer' - pointer to a buffer where the function can store additional - data for the result etc. +Orphaned Process Groups +======================= - `size_t buflen' - length of the buffer pointed to by BUFFER. + When a controlling process terminates, its terminal becomes free and +a new session can be established on it. (In fact, another user could +log in on the terminal.) This could cause a problem if any processes +from the old session are still trying to use that terminal. - * possibly a last argument H_ERRNOP, for the host name and network - name lookup functions. + To prevent problems, process groups that continue running even after +the session leader has terminated are marked as "orphaned process +groups". -This table is correct for all functions but the `set...ent' and -`end...ent' functions. + When a process group becomes an orphan, its processes are sent a +`SIGHUP' signal. Ordinarily, this causes the processes to terminate. +However, if a program ignores this signal or establishes a handler for +it (*note Signal Handling::), it can continue running as in the orphan +process group even after its controlling process terminates; but it +still cannot access the terminal any more.  -File: libc.info, Node: Extending NSS, Prev: NSS Module Internals, Up: Name Service Switch - -Extending NSS -============= +File: libc.info, Node: Implementing a Shell, Next: Functions for Job Control, Prev: Orphaned Process Groups, Up: Job Control - One of the advantages of NSS mentioned above is that it can be -extended quite easily. There are two ways in which the extension can -happen: adding another database or adding another service. The former -is normally done only by the C library developers.

The developer retains complete control over -the sources and its development. The links between the C library and -the new service module consists solely of the interface functions. - - Each module is designed following a specific interface specification. -For now the version is 2 (the interface in version 1 was not adequate) -and this manifests in the version number of the shared library object of -the NSS modules: they have the extension `.2'. If the interface -changes again in an incompatible way, this number will be increased. -Modules using the old interface will still be usable. - - Developers of a new service will have to make sure that their module -is created using the correct interface number. This means the file -itself must have the correct name and on ELF systems the "soname" -(Shared Object Name) must also have this number. Building a module -from a bunch of object files on an ELF system using GNU CC could be -done like this: + All of the program examples included in this chapter are part of a +simple shell program. This section presents data structures and +utility functions which are used throughout the example. - gcc -shared -o libnss_NAME.so.2 -Wl,-soname,libnss_NAME.so.2 OBJECTS + The sample shell deals mainly with two data structures. The `job' +type contains information about a job, which is a set of subprocesses +linked together with pipes. The `process' type holds information about +a single subprocess. Here are the relevant data structure declarations: -*Note Options for Linking: (gcc)Link Options, to learn more about this -command line. + /* A process is a single process. */ + typedef struct process + { + struct process *next; /* next process in pipeline */ + char **argv; /* for exec */ + pid_t pid; /* process ID */ + char completed; /* true if process has completed */ + char stopped; /* true if process has stopped */ + int status; /* reported status value */ + } process; + + /* A job is a pipeline of processes. */ + typedef struct job + { + struct job *next; /* next active job */ + char *command; /* command line, used for messages */ + process *first_process; /* list of processes in this job */ + pid_t pgid; /* process group ID */ + char notified; /* true if user told about stopped job */ + struct termios tmodes; /* saved terminal modes */ + int stdin, stdout, stderr; /* standard i/o channels */ + } job; + + /* The active jobs are linked into a list. This is its head. */ + job *first_job = NULL; - To use the new module the library must be able to find it. This can -be achieved by using options for the dynamic linker so that it will -search the directory where the binary is placed. For an ELF system -this could be done by adding the wanted directory to the value of -`LD_LIBRARY_PATH'. + Here are some utility functions that are used for operating on `job' +objects. - But this is not always possible since some programs (those which run -under IDs which do not belong to the user) ignore this variable. -Therefore the stable version of the module should be placed into a -directory which is searched by the dynamic linker. Normally this should -be the directory `$prefix/lib', where `$prefix' corresponds to the -value given to configure using the `--prefix' option.

In fact there is not much more we can say since the -implementation obviously is different for each function. But a few -general rules must be followed by all functions. + When a shell program that normally performs job control is started, +it has to be careful in case it has been invoked from another shell +that is already doing its own job control. - In fact there are four kinds of different functions which may appear -in the interface. All derive from the traditional ones for system -databases. DB in the following table is normally an abbreviation for -the database (e.g., it is `pw' for the password database). + A subshell that runs interactively has to ensure that it has been +placed in the foreground by its parent shell before it can enable job +control itself. It does this by getting its initial process group ID +with the `getpgrp' function, and comparing it to the process group ID +of the current foreground job associated with its controlling terminal +(which can be retrieved using the `tcgetpgrp' function). -`enum nss_status _nss_DATABASE_setDBent (void)' - This function prepares the service for following operations. For a - simple file based lookup this means files could be opened, for - other services this function simply is a noop. + If the subshell is not running as a foreground job, it must stop +itself by sending a `SIGTTIN' signal to its own process group. It may +not arbitrarily put itself into the foreground; it must wait for the +user to tell the parent shell to do this. If the subshell is continued +again, it should repeat the check and stop itself again if it is still +not in the foreground. - One special case for this function is that it takes an additional - argument for some DATABASEs (i.e., the interface is `int setDBent - (int)'). *Note Host Names::, which describes the `sethostent' - function. + Once the subshell has been placed into the foreground by its parent +shell, it can enable its own job control. It does this by calling +`setpgid' to put itself into its own process group, and then calling +`tcsetpgrp' to place this process group into the foreground. - The return value should be NSS_STATUS_SUCCESS or according to the - table above in case of an error (*note NSS Modules Interface::). + When a shell enables job control, it should set itself to ignore all +the job control stop signals so that it doesn't accidentally stop +itself. You can do this by setting the action for all the stop signals +to `SIG_IGN'. -`enum nss_status _nss_DATABASE_endDBent (void)' - This function simply closes all files which are still open or - removes buffer caches. If there are no files or buffers to remove - this is again a simple noop. + A subshell that runs non-interactively cannot and should not support +job control. It must leave all processes it creates in the same process +group as the shell itself; this allows the non-interactive shell and its +child processes to be treated as a single job by the parent shell. This +is easy to do--just don't use any of the job control primitives--but +you must remember to make the shell do it. - There normally is no return value different to NSS_STATUS_SUCCESS. + Here is the initialization code for the sample shell that shows how +to do all of this. -`enum nss_status _nss_DATABASE_getDBent_r (STRUCTURE *result, char *buffer, size_t buflen, int *errnop)' - Since this function will be called several times in a row to - retrieve one entry after the other it must keep some kind of - state. But this also means the functions are not really - reentrant. They are reentrant only in that simultaneous calls to - this function will not try to write the retrieved data in the same - place (as it would be the case for the non-reentrant functions); - instead, it writes to the structure pointed to by the RESULT - parameter. But the calls share a common state and in the case of - a file access this means they return neighboring entries in the - file. + /* Keep track of attributes of the shell. */ + + #include + #include + #include + + pid_t shell_pgid; + struct termios shell_tmodes; + int shell_terminal; + int shell_is_interactive; + + + /* Make sure the shell is running interactively as the foreground job + before proceeding. */ + + void + init_shell () + { + + /* See if we are running interactively. */ + shell_terminal = STDIN_FILENO; + shell_is_interactive = isatty (shell_terminal); + + if (shell_is_interactive) + { + /* Loop until we are in the foreground. */ + while (tcgetpgrp (shell_terminal) != (shell_pgid = getpgrp ())) + kill (- shell_pgid, SIGTTIN); + + /* Ignore interactive and job-control signals. */ + signal (SIGINT, SIG_IGN); + signal (SIGQUIT, SIG_IGN); + signal (SIGTSTP, SIG_IGN); + signal (SIGTTIN, SIG_IGN); + signal (SIGTTOU, SIG_IGN); + signal (SIGCHLD, SIG_IGN); + + /* Put ourselves in our own process group. */ + shell_pgid = getpid (); + if (setpgid (shell_pgid, shell_pgid) < 0) + { + perror ("Couldn't put the shell in its own process group"); + exit (1); + } + + /* Grab control of the terminal. */ + tcsetpgrp (shell_terminal, shell_pgid); + + /* Save default terminal attributes for shell. */ + tcgetattr (shell_terminal, &shell_tmodes); + } + } - The buffer of length BUFLEN pointed to by BUFFER can be used for - storing some additional data for the result.

This is important to guarantee the module working in - statically linked programs. +Launching Jobs +-------------- - As explained above this function could also have an additional last - argument. This depends on the database used; it happens only for - `host' and `networks'. + Once the shell has taken responsibility for performing job control on +its controlling terminal, it can launch jobs in response to commands +typed by the user. - The function shall return `NSS_STATUS_SUCCESS' as long as there are - more entries. When the last entry was read it should return - `NSS_STATUS_NOTFOUND'. When the buffer given as an argument is too - small for the data to be returned `NSS_STATUS_TRYAGAIN' should be - returned. When the service was not formerly initialized by a call - to `_nss_DATABASE_setDBent' all return value allowed for this - function can also be returned here. + To create the processes in a process group, you use the same `fork' +and `exec' functions described in *Note Process Creation Concepts::. +Since there are multiple child processes involved, though, things are a +little more complicated and you must be careful to do things in the +right order. Otherwise, nasty race conditions can result. -`enum nss_status _nss_DATABASE_getDBbyXX_r (PARAMS, STRUCTURE *result, char *buffer, size_t buflen, int *errnop)' - This function shall return the entry from the database which is - addressed by the PARAMS. The type and number of these arguments - vary. It must be individually determined by looking to the - user-level interface functions. All arguments given to the - non-reentrant version are here described by PARAMS. + You have two choices for how to structure the tree of parent-child +relationships among the processes. You can either make all the +processes in the process group be children of the shell process, or you +can make one process in group be the ancestor of all the other processes +in that group. The sample shell program presented in this chapter uses +the first approach because it makes bookkeeping somewhat simpler. - The result must be stored in the structure pointed to by RESULT. - If there is additional data to return (say strings, where the - RESULT structure only contains pointers) the function must use the - BUFFER or length BUFLEN. There must not be any references to - non-constant global data. + As each process is forked, it should put itself in the new process +group by calling `setpgid'; see *Note Process Group Functions::. The +first process in the new group becomes its "process group leader", and +its process ID becomes the "process group ID" for the group. - The implementation of this function should honor the STAYOPEN flag - set by the `setDBent' function whenever this makes sense. + The shell should also call `setpgid' to put each of its child +processes into the new process group. This is because there is a +potential timing problem: each child process must be put in the process +group before it begins executing a new program, and the shell depends on +having all the child processes in the group before it continues +executing. If both the child processes and the shell call `setpgid', +this ensures that the right things happen no matter which process gets +to it first. - Before the function returns the implementation should store the - value of the local ERRNO variable in the variable pointed to be - ERRNOP. This is important to guarantee the module working in - statically linked programs. + If the job is being launched as a foreground job, the new process +group also needs to be put into the foreground on the controlling +terminal using `tcsetpgrp'. Again, this should be done by the shell as +well as by each of its child processes, to avoid race conditions. - Again, this function takes an additional last argument for the - `host' and `networks' database. + The next thing each child process should do is to reset its signal +actions. - The return value should as always follow the rules given above - (*note NSS Modules Interface::). + During initialization, the shell process set itself to ignore job +control signals; see *Note Initializing the Shell::. As a result, any +child processes it creates also ignore these signals by inheritance. +This is definitely undesirable, so each child process should explicitly +set the actions for these signals back to `SIG_DFL' just after it is +forked. - -File: libc.info, Node: Users and Groups, Next: System Management, Prev: Name Service Switch, Up: Top + Since shells follow this convention, applications can assume that +they inherit the correct handling of these signals from the parent +process. But every application has a responsibility not to mess up the +handling of stop signals. Applications that disable the normal +interpretation of the SUSP character should provide some other +mechanism for the user to stop the job. When the user invokes this +mechanism, the program should send a `SIGTSTP' signal to the process +group of the process, not just to the process itself. *Note Signaling +Another Process::. -Users and Groups -**************** + Finally, each child process should call `exec' in the normal way. +This is also the point at which redirection of the standard input and +output channels should be handled. *Note Duplicating Descriptors::, +for an explanation of how to do this. - Every user who can log in on the system is identified by a unique -number called the "user ID".

These IDs determine -the privileges of the process. They are collectively called the -"persona" of the process, because they determine "who it is" for -purposes of access control. +Stopped and Terminated Jobs +--------------------------- - Your login shell starts out with a persona which consists of your -user ID, your default group ID, and your supplementary group IDs (if -you are in more than one group). In normal circumstances, all your -other processes inherit these values. + When a foreground process is launched, the shell must block until +all of the processes in that job have either terminated or stopped. It +can do this by calling the `waitpid' function; see *Note Process +Completion::. Use the `WUNTRACED' option so that status is reported +for processes that stop as well as processes that terminate. - A process also has a "real user ID" which identifies the user who -created the process, and a "real group ID" which identifies that user's -default group. These values do not play a role in access control, so -we do not consider them part of the persona. But they are also -important. + The shell must also check on the status of background jobs so that it +can report terminated and stopped jobs to the user; this can be done by +calling `waitpid' with the `WNOHANG' option. A good place to put a +such a check for terminated and stopped jobs is just before prompting +for a new command. - Both the real and effective user ID can be changed during the -lifetime of a process. *Note Why Change Persona::. + The shell can also receive asynchronous notification that there is +status information available for a child process by establishing a +handler for `SIGCHLD' signals. *Note Signal Handling::. - For details on how a process's effective user ID and group IDs affect -its permission to access files, see *Note Access Permission::. + In the sample shell program, the `SIGCHLD' signal is normally +ignored. This is to avoid reentrancy problems involving the global data +structures the shell manipulates. But at specific times when the shell +is not using these data structures--such as when it is waiting for +input on the terminal--it makes sense to enable a handler for +`SIGCHLD'. The same function that is used to do the synchronous status +checks (`do_job_notification', in this case) can also be called from +within this handler. - The effective user ID of a process also controls permissions for -sending signals using the `kill' function. *Note Signaling Another -Process::. + Here are the parts of the sample shell program that deal with +checking the status of jobs and reporting the information to the user. - Finally, there are many operations which can only be performed by a -process whose effective user ID is zero. A process with this user ID is -a "privileged process".

When `login' -starts running, its user ID is `root'. Its job is to start a shell -whose user and group IDs are those of the user who is logging in. (To -accomplish this fully, `login' must set the real user and group IDs as -well as its persona. But this is a special case.) + The shell can continue a stopped job by sending a `SIGCONT' signal +to its process group. If the job is being continued in the foreground, +the shell should first invoke `tcsetpgrp' to give the job access to the +terminal, and restore the saved terminal settings. After continuing a +job in the foreground, the shell should wait for the job to stop or +complete, as if the job had just been launched in the foreground. - The more common case of changing persona is when an ordinary user -program needs access to a resource that wouldn't ordinarily be -accessible to the user actually running it. + The sample shell program handles both newly created and continued +jobs with the same pair of functions, `put_job_in_foreground' and +`put_job_in_background'. The definitions of these functions were given +in *Note Foreground and Background::. When continuing a stopped job, a +nonzero value is passed as the CONT argument to ensure that the +`SIGCONT' signal is sent and the terminal modes reset, as appropriate. - For example, you may have a file that is controlled by your program -but that shouldn't be read or modified directly by other users, either -because it implements some kind of locking protocol, or because you want -to preserve the integrity or privacy of the information it contains. -This kind of restricted access can be implemented by having the program -change its effective user or group ID to match that of the resource. + This leaves only a function for updating the shell's internal +bookkeeping about the job being continued: - Thus, imagine a game program that saves scores in a file. The game -program itself needs to be able to update this file no matter who is -running it, but if users can write the file without going through the -game, they can give themselves any scores they like. Some people -consider this undesirable, or even reprehensible. It can be prevented -by creating a new user ID and login name (say, `games') to own the -scores file, and make the file writable only by this user. Then, when -the game program wants to update this file, it can change its effective -user ID to be that for `games'.

Because of -the potential for problems, changing persona is restricted to special -circumstances. + The code extracts for the sample shell included in this chapter are +only a part of the entire shell program. In particular, nothing at all +has been said about how `job' and `program' data structures are +allocated and initialized. - You can't arbitrarily set your user ID or group ID to anything you -want; only privileged processes can do that. Instead, the normal way -for a program to change its persona is that it has been set up in -advance to change to a particular user or group. This is the function -of the setuid and setgid bits of a file's access mode. *Note -Permission Bits::. + Most real shells provide a complex user interface that has support +for a command language; variables; abbreviations, substitutions, and +pattern matching on file names; and the like. All of this is far too +complicated to explain here! Instead, we have concentrated on showing +how to implement the core process creation and job control functions +that can be called from such a shell. - When the setuid bit of an executable file is on, executing that file -gives the process a third user ID: the "file user ID". This ID is set -to the owner ID of the file. The system then changes the effective -user ID to the file user ID. The real user ID remains as it was. -Likewise, if the setgid bit is on, the process is given a "file group -ID" equal to the group ID of the file, and its effective group ID is -changed to the file group ID. + Here is a table summarizing the major entry points we have presented: - If a process has a file ID (user or group), then it can at any time -change its effective ID to its real ID and back to its file ID. -Programs use this feature to relinquish their special privileges except -when they actually need them. This makes it less likely that they can -be tricked into doing something inappropriate with their privileges. +`void init_shell (void)' + Initialize the shell's internal state. *Note Initializing the + Shell::. - *Portability Note:* Older systems do not have file IDs.

I.e., `!' +is negation as in the C language (and others). - The `ut_type', `ut_pid', `ut_id', `ut_tv', and `ut_host' fields are -not available on all systems. Portable applications therefore should -be prepared for these situations. To help doing this the `utmp.h' -header provides macros `_HAVE_UT_TYPE', `_HAVE_UT_PID', `_HAVE_UT_ID', -`_HAVE_UT_TV', and `_HAVE_UT_HOST' if the respective field is -available. The programmer can handle the situations by using `#ifdef' -in the program code. + Before we explain the exception which makes this action item +necessary one more remark: obviously it makes no sense to add another +action item after the `files' service. Since there is no other service +following the action _always_ is `return'. - The following macros are defined for use as values for the `ut_type' -member of the `utmp' structure. The values are integer constants. + Now, why is this `[NOTFOUND=return]' action useful? To understand +this we should know that the `nisplus' service is often complete; i.e., +if an entry is not available in the NIS+ tables it is not available +anywhere else. This is what is expressed by this action item: it is +useless to examine further services since they will not give us a +result. -`EMPTY' - This macro is used to indicate that the entry contains no valid - user accounting information. + The situation would be different if the NIS+ service is not available +because the machine is booting. In this case the return value of the +lookup function is not `notfound' but instead `unavail'. And as you +can see in the complete form above: in this situation the `db' and +`files' services are used. Neat, isn't it? The system administrator +need not pay special care for the time the system is not completely +ready to work (while booting or shutdown or network problems). -`RUN_LVL' - This macro is used to identify the systems runlevel. + +File: libc.info, Node: Notes on NSS Configuration File, Prev: Actions in the NSS configuration, Up: NSS Configuration File -`BOOT_TIME' - This macro is used to identify the time of system boot. +Notes on the NSS Configuration File +----------------------------------- -`OLD_TIME' - This macro is used to identify the time when the system clock - changed. + Finally a few more hints. The NSS implementation is not completely +helpless if `/etc/nsswitch.conf' does not exist. For all supported +databases there is a default value so it should normally be possible to +get the system running even if the file is corrupted or missing. -`NEW_TIME' - This macro is used to identify the time after the system changed. + For the `hosts' and `networks' databases the default value is `dns +[!UNAVAIL=return] files'. I.e., the system is prepared for the DNS +service not to be available but if it is available the answer it +returns is definitive. -`INIT_PROCESS' - This macro is used to identify a process spawned by the init - process. + The `passwd', `group', and `shadow' databases are traditionally +handled in a special way. The appropriate files in the `/etc' +directory are read but if an entry with a name starting with a `+' +character is found NIS is used. This kind of lookup remains possible +by using the special lookup service `compat' and the default value for +the three databases above is `compat [NOTFOUND=return] files'. -`LOGIN_PROCESS' - This macro is used to identify the session leader of a logged in - user. + For all other databases the default value is `nis [NOTFOUND=return] +files'. This solution give the best chance to be correct since NIS and +file based lookup is used. -`USER_PROCESS' - This macro is used to identify a user process. + A second point is that the user should try to optimize the lookup +process. The different service have different response times. A +simple file look up on a local file could be fast, but if the file is +long and the needed entry is near the end of the file this may take +quite some time. In this case it might be better to use the `db' +service which allows fast local access to large data sets. -`DEAD_PROCESS' - This macro is used to identify a terminated process. + Often the situation is that some global information like NIS must be +used. So it is unavoidable to use service entries like `nis' etc. But +one should avoid slow services like this if possible. -`ACCOUNTING' - ??? + +File: libc.info, Node: NSS Module Internals, Next: Extending NSS, Prev: NSS Configuration File, Up: Name Service Switch - The size of the `ut_line', `ut_id', `ut_user' and `ut_host' arrays -can be found using the `sizeof' operator. +NSS Module Internals +==================== - Many older systems have, instead of an `ut_tv' member, an `ut_time' -member, usually of type `time_t', for representing the time associated -with the entry.

The functions +contained in a module are identified by their names. I.e., there is no +jump table or the like. How this is done is of no interest here; those +interested in this topic should read about Dynamic Linking. - - Function: void setutent (void) - This function opens the user accounting database to begin scanning - it.

It returns a pointer to the entry, which is - statically allocated and may be overwritten by subsequent calls to - `getutent'. You must copy the contents of the structure if you - wish to save the information or you can use the `getutent_r' - function which stores the data in a user-provided buffer. + +File: libc.info, Node: NSS Module Names, Next: NSS Modules Interface, Prev: NSS Module Internals, Up: NSS Module Internals - A null pointer is returned in case no further entry is available. +The Naming Scheme of the NSS Modules +------------------------------------ - - Function: void endutent (void) - This function closes the user accounting database. +The name of each function consist of various parts: - - Function: struct utmp * getutid (const struct utmp *ID) - This function searches forward from the current point in the - database for an entry that matches ID. If the `ut_type' member of - the ID structure is one of `RUN_LVL', `BOOT_TIME', `OLD_TIME' or - `NEW_TIME' the entries match if the `ut_type' members are - identical. If the `ut_type' member of the ID structure is - `INIT_PROCESS', `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS', - the entries match if the `ut_type' member of the entry read from - the database is one of these four, and the `ut_id' members match. - However if the `ut_id' member of either the ID structure or the - entry read from the database is empty it checks if the `ut_line' - members match instead. If a matching entry is found, `getutid' - returns a pointer to the entry, which is statically allocated, and - may be overwritten by a subsequent call to `getutent', `getutid' - or `getutline'. You must copy the contents of the structure if - you wish to save the information. + _nss_SERVICE_FUNCTION - A null pointer is returned in case the end of the database is - reached without a match. + SERVICE of course corresponds to the name of the module this +function is found in.(1) The FUNCTION part is derived from the +interface function in the C library itself. If the user calls the +function `gethostbyname' and the service used is `files' the function - The `getutid' function may cache the last read entry. Therefore, - if you are using `getutid' to search for multiple occurrences, it - is necessary to zero out the static data after each call. - Otherwise `getutid' could just return a pointer to the same entry - over and over again. + _nss_files_gethostbyname_r - - Function: struct utmp * getutline (const struct utmp *LINE) - This function searches forward from the current point in the - database until it finds an entry whose `ut_type' value is - `LOGIN_PROCESS' or `USER_PROCESS', and whose `ut_line' member - matches the `ut_line' member of the LINE structure. If it finds - such an entry, it returns a pointer to the entry which is - statically allocated, and may be overwritten by a subsequent call - to `getutent', `getutid' or `getutline'. You must copy the - contents of the structure if you wish to save the information. +in the module - A null pointer is returned in case the end of the database is - reached without a match. + libnss_files.so.2 - The `getutline' function may cache the last read entry. Therefore - if you are using `getutline' to search for multiple occurrences, it - is necessary to zero out the static data after each call. - Otherwise `getutline' could just return a pointer to the same - entry over and over again. +is used. You see, what is explained above in not the whole truth. In +fact the NSS modules only contain reentrant versions of the lookup +functions. I.e., if the user would call the `gethostbyname_r' function +this also would end in the above function. For all user interface +functions the C library maps this call to a call to the reentrant +function. For reentrant functions this is trivial since the interface +is (nearly) the same. For the non-reentrant version The library keeps +internal buffers which are used to replace the user supplied buffer. - - Function: struct utmp * pututline (const struct utmp *UTMP) - The `pututline' function inserts the entry `*UTMP' at the - appropriate place in the user accounting database. If it finds - that it is not already at the correct place in the database, it - uses `getutid' to search for the position to insert the entry, - however this will not modify the static structure returned by - `getutent', `getutid' and `getutline'. If this search fails, the - entry is appended to the database. + I.e., the reentrant functions _can_ have counterparts. No service +module is forced to have functions for all databases and all kinds to +access them. If a function is not available it is simply treated as if +the function would return `unavail' (*note Actions in the NSS +configuration::). - The `pututline' function returns a pointer to a copy of the entry - inserted in the user accounting database, or a null pointer if the - entry could not be added. The following `errno' error conditions - are defined for this function: + The file name `libnss_files.so.2' would be on a Solaris 2 system +`nss_files.so.2'. This is the difference mentioned above. Sun's NSS +modules are usable as modules which get indirectly loaded only. - `EPERM' - The process does not have the appropriate privileges; you - cannot modify the user accounting database. + The NSS modules in the GNU C Library are prepared to be used as +normal libraries themselves. This is _not_ true at the moment, though. +However, the organization of the name space in the modules does not +make it impossible like it is for Solaris. Now you can see why the +modules are still libraries.(2) - All the `get*' functions mentioned before store the information they -return in a static buffer. This can be a problem in multi-threaded -programs since the data returned for the request is overwritten by the -return value data in another thread. Therefore the GNU C Library -provides as extensions three more functions which return the data in a -user-provided buffer. + ---------- Footnotes ---------- - - Function: int getutent_r (struct utmp *BUFFER, struct utmp **RESULT) - The `getutent_r' is equivalent to the `getutent' function. It - returns the next entry from the database. But instead of storing - the information in a static buffer it stores it in the buffer - pointed to by the parameter BUFFER. + (1) Now you might ask why this information is duplicated. The +answer is that we want to make it possible to link directly with these +shared objects. - If the call was successful, the function returns `0' and the - pointer variable pointed to by the parameter RESULT contains a - pointer to the buffer which contains the result (this is most - probably the same value as BUFFER). If something went wrong - during the execution of `getutent_r' the function returns `-1'. + (2) There is a second explanation: we were too lazy to change the +Makefiles to allow the generation of shared objects not starting with +`lib' but don't tell this to anybody. - This function is a GNU extension. + +File: libc.info, Node: NSS Modules Interface, Prev: NSS Module Names, Up: NSS Module Internals - - Function: int getutid_r (const struct utmp *ID, struct utmp *BUFFER, - struct utmp **RESULT) - This function retrieves just like `getutid' the next entry matching - the information stored in ID. But the result is stored in the - buffer pointed to by the parameter BUFFER. +The Interface of the Function in NSS Modules +-------------------------------------------- - If successful the function returns `0' and the pointer variable - pointed to by the parameter RESULT contains a pointer to the - buffer with the result (probably the same as RESULT. If not - successful the function return `-1'. + Now we know about the functions contained in the modules. It is now +time to describe the types. When we mentioned the reentrant versions of +the functions above, this means there are some additional arguments +(compared with the standard, non-reentrant version). The prototypes for +the non-reentrant and reentrant versions of our function above are: - This function is a GNU extension. + struct hostent *gethostbyname (const char *name) + + int gethostbyname_r (const char *name, struct hostent *result_buf, + char *buf, size_t buflen, struct hostent **result, + int *h_errnop) - - Function: int getutline_r (const struct utmp *LINE, struct utmp - *BUFFER, struct utmp **RESULT) - This function retrieves just like `getutline' the next entry - matching the information stored in LINE. But the result is stored - in the buffer pointed to by the parameter BUFFER. +The actual prototype of the function in the NSS modules in this case is - If successful the function returns `0' and the pointer variable - pointed to by the parameter RESULT contains a pointer to the - buffer with the result (probably the same as RESULT. If not - successful the function return `-1'. + enum nss_status _nss_files_gethostbyname_r (const char *name, + struct hostent *result_buf, + char *buf, size_t buflen, + int *errnop, int *h_errnop) - This function is a GNU extension. + I.e., the interface function is in fact the reentrant function with +the change of the return value and the omission of the RESULT +parameter. While the user-level function returns a pointer to the +result the reentrant function return an `enum nss_status' value: - In addition to the user accounting database, most systems keep a -number of similar databases. For example most systems keep a log file -with all previous logins (usually in `/etc/wtmp' or `/var/log/wtmp'). +`NSS_STATUS_TRYAGAIN' + numeric value `-2' - For specifying which database to examine, the following function -should be used. +`NSS_STATUS_UNAVAIL' + numeric value `-1' - - Function: int utmpname (const char *FILE) - The `utmpname' function changes the name of the database to be - examined to FILE, and closes any previously opened database. By - default `getutent', `getutid', `getutline' and `pututline' read - from and write to the user accounting database. +`NSS_STATUS_NOTFOUND' + numeric value `0' - The following macros are defined for use as the FILE argument: +`NSS_STATUS_SUCCESS' + numeric value `1' - - Macro: char * _PATH_UTMP - This macro is used to specify the user accounting database. +Now you see where the action items of the `/etc/nsswitch.conf' file are +used. - - Macro: char * _PATH_WTMP - This macro is used to specify the user accounting log file. + If you study the source code you will find there is a fifth value: +`NSS_STATUS_RETURN'. This is an internal use only value, used by a few +functions in places where none of the above value can be used. If +necessary the source code should be examined to learn about the details. - The `utmpname' function returns a value of `0' if the new name was - successfully stored, and a value of `-1' to indicate an error. - Note that `utmpname' does not try to open the database, and that - therefore the return value does not say anything about whether the - database can be successfully opened. + In case the interface function has to return an error it is important +that the correct error code is stored in `*ERRNOP'. Some return status +value have only one associated error code, others have more. - Specially for maintaining log-like databases the GNU C Library -provides the following function: +`NSS_STATUS_TRYAGAIN' `EAGAIN' One of the functions used ran + temporarily out of resources or a + service is currently not available. + `ERANGE' The provided buffer is not large + enough. The function should be + called again with a larger buffer. +`NSS_STATUS_UNAVAIL' `ENOENT' A necessary input file cannot be + found. +`NSS_STATUS_NOTFOUND' `ENOENT' The requested entry is not + available. - - Function: void updwtmp (const char *WTMP_FILE, const struct utmp - *UTMP) - The `updwtmp' function appends the entry *UTMP to the database - specified by WTMP_FILE. For possible values for the WTMP_FILE - argument see the `utmpname' function. + These are proposed values. There can be other error codes and the +described error codes can have different meaning. *With one +exception:* when returning `NSS_STATUS_TRYAGAIN' the error code +`ERANGE' _must_ mean that the user provided buffer is too small. +Everything is non-critical. - *Portability Note:* Although many operating systems provide a subset -of these functions, they are not standardized. There are often subtle -differences in the return types, and there are considerable differences -between the various definitions of `struct utmp'. When programming for -the GNU system, it is probably best to stick with the functions -described in this section. If however, you want your program to be -portable, consider using the XPG functions described in *Note XPG -Functions::, or take a look at the BSD compatible functions in *Note -Logging In and Out::. + The above function has something special which is missing for almost +all the other module functions. There is an argument H_ERRNOP. This +points to a variable which will be filled with the error code in case +the execution of the function fails for some reason. The reentrant +function cannot use the global variable H_ERRNO; `gethostbyname' calls +`gethostbyname_r' with the last argument set to `&h_errno'. - -File: libc.info, Node: XPG Functions, Next: Logging In and Out, Prev: Manipulating the Database, Up: User Accounting Database + The `getXXXbyYYY' functions are the most important functions in the +NSS modules. But there are others which implement the other ways to +access system databases (say for the password database, there are +`setpwent', `getpwent', and `endpwent'). These will be described in +more detail later. Here we give a general way to determine the +signature of the module function: -XPG User Accounting Database Functions --------------------------------------- + * the return value is `int'; - These functions, described in the X/Open Portability Guide, are -declared in the header file `utmpx.h'. + * the name is as explained in *note NSS Module Names::; - - Data Type: struct utmpx - The `utmpx' data structure contains at least the following members: + * the first arguments are identical to the arguments of the + non-reentrant function; - `short int ut_type' - Specifies the type of login; one of `EMPTY', `RUN_LVL', - `BOOT_TIME', `OLD_TIME', `NEW_TIME', `INIT_PROCESS', - `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS'. + * the next three arguments are: - `pid_t ut_pid' - The process ID number of the login process. + `STRUCT_TYPE *result_buf' + pointer to buffer where the result is stored. `STRUCT_TYPE' + is normally a struct which corresponds to the database. - `char ut_line[]' - The device name of the tty (without `/dev/'). + `char *buffer' + pointer to a buffer where the function can store additional + data for the result etc. - `char ut_id[]' - The inittab ID of the process. + `size_t buflen' + length of the buffer pointed to by BUFFER. - `char ut_user[]' - The user's login name. + * possibly a last argument H_ERRNOP, for the host name and network + name lookup functions. - `struct timeval ut_tv' - Time the entry was made. For entries of type `OLD_TIME' this - is the time when the system clock changed, and for entries of - type `NEW_TIME' this is the time the system clock was set to. - On the GNU system, `struct utmpx' is identical to `struct utmp' - except for the fact that including `utmpx.h' does not make visible - the declaration of `struct exit_status'. +This table is correct for all functions but the `set...ent' and +`end...ent' functions. - The following macros are defined for use as values for the `ut_type' -member of the `utmpx' structure. The values are integer constants and -are, on the GNU system, identical to the definitions in `utmp.h'. + +File: libc.info, Node: Extending NSS, Prev: NSS Module Internals, Up: Name Service Switch -`EMPTY' - This macro is used to indicate that the entry contains no valid - user accounting information. +Extending NSS +============= -`RUN_LVL' - This macro is used to identify the systems runlevel. + One of the advantages of NSS mentioned above is that it can be +extended quite easily. There are two ways in which the extension can +happen: adding another database or adding another service. The former +is normally done only by the C library developers. It is here only +important to remember that adding another database is independent from +adding another service because a service need not support all databases +or lookup functions. -`BOOT_TIME' - This macro is used to identify the time of system boot. + A designer/implementor of a new service is therefore free to choose +the databases s/he is interested in and leave the rest for later (or +completely aside). -`OLD_TIME' - This macro is used to identify the time when the system clock - changed. +* Menu: -`NEW_TIME' - This macro is used to identify the time after the system changed. +* Adding another Service to NSS:: What is to do to add a new service. +* NSS Module Function Internals:: Guidelines for writing new NSS + service functions. -`INIT_PROCESS' - This macro is used to identify a process spawned by the init - process. + +File: libc.info, Node: Adding another Service to NSS, Next: NSS Module Function Internals, Prev: Extending NSS, Up: Extending NSS -`LOGIN_PROCESS' - This macro is used to identify the session leader of a logged in - user. +Adding another Service to NSS +----------------------------- -`USER_PROCESS' - This macro is used to identify a user process. + The sources for a new service need not (and should not) be part of +the GNU C Library itself. The developer retains complete control over +the sources and its development. The links between the C library and +the new service module consists solely of the interface functions. -`DEAD_PROCESS' - This macro is used to identify a terminated process. + Each module is designed following a specific interface specification. +For now the version is 2 (the interface in version 1 was not adequate) +and this manifests in the version number of the shared library object of +the NSS modules: they have the extension `.2'. If the interface +changes again in an incompatible way, this number will be increased. +Modules using the old interface will still be usable. - The size of the `ut_line', `ut_id' and `ut_user' arrays can be found -using the `sizeof' operator. + Developers of a new service will have to make sure that their module +is created using the correct interface number. This means the file +itself must have the correct name and on ELF systems the "soname" +(Shared Object Name) must also have this number. Building a module +from a bunch of object files on an ELF system using GNU CC could be +done like this: - - Function: void setutxent (void) - This function is similar to `setutent'. On the GNU system it is - simply an alias for `setutent'. + gcc -shared -o libnss_NAME.so.2 -Wl,-soname,libnss_NAME.so.2 OBJECTS - - Function: struct utmpx * getutxent (void) - The `getutxent' function is similar to `getutent', but returns a - pointer to a `struct utmpx' instead of `struct utmp'. On the GNU - system it simply is an alias for `getutent'. +*Note Options for Linking: (gcc)Link Options, to learn more about this +command line. - - Function: void endutxent (void) - This function is similar to `endutent'. On the GNU system it is - simply an alias for `endutent'. + To use the new module the library must be able to find it. This can +be achieved by using options for the dynamic linker so that it will +search the directory where the binary is placed. For an ELF system +this could be done by adding the wanted directory to the value of +`LD_LIBRARY_PATH'. - - Function: struct utmpx * getutxid (const struct utmpx *ID) - This function is similar to `getutid', but uses `struct utmpx' - instead of `struct utmp'. On the GNU system it is simply an alias - for `getutid'. + But this is not always possible since some programs (those which run +under IDs which do not belong to the user) ignore this variable. +Therefore the stable version of the module should be placed into a +directory which is searched by the dynamic linker. Normally this should +be the directory `$prefix/lib', where `$prefix' corresponds to the +value given to configure using the `--prefix' option. But be careful: +this should only be done if it is clear the module does not cause any +harm. System administrators should be careful. - - Function: struct utmpx * getutxline (const struct utmpx *LINE) - This function is similar to `getutid', but uses `struct utmpx' - instead of `struct utmp'.

On - the GNU system, `pututxline' is simply an alias for `pututline'. +Internals of the NSS Module Functions +------------------------------------- - - Function: int utmpxname (const char *FILE) - The `utmpxname' function is functionally identical to `utmpname'. - On the GNU system, `utmpxname' is simply an alias for `utmpname'. + Until now we only provided the syntactic interface for the functions +in the NSS module. In fact there is not much more we can say since the +implementation obviously is different for each function. But a few +general rules must be followed by all functions. - You can translate between a traditional `struct utmp' and an XPG -`struct utmpx' with the following functions. On the GNU system, these -functions are merely copies, since the two structures are identical. + In fact there are four kinds of different functions which may appear +in the interface. All derive from the traditional ones for system +databases. DB in the following table is normally an abbreviation for +the database (e.g., it is `pw' for the password database). - - Function: int getutmp (const struct utmpx *utmpx, struct utmp *utmp) - `getutmp' copies the information, insofar as the structures are - compatible, from UTMPX to UTMP. +`enum nss_status _nss_DATABASE_setDBent (void)' + This function prepares the service for following operations. For a + simple file based lookup this means files could be opened, for + other services this function simply is a noop. - - Function: int getutmpx (const struct utmp *utmp, struct utmpx *utmpx) - `getutmpx' copies the information, insofar as the structures are - compatible, from UTMP to UTMPX. + One special case for this function is that it takes an additional + argument for some DATABASEs (i.e., the interface is `int setDBent + (int)'). *Note Host Names::, which describes the `sethostent' + function. - -File: libc.info, Node: Logging In and Out, Prev: XPG Functions, Up: User Accounting Database + The return value should be NSS_STATUS_SUCCESS or according to the + table above in case of an error (*note NSS Modules Interface::). -Logging In and Out ------------------- +`enum nss_status _nss_DATABASE_endDBent (void)' + This function simply closes all files which are still open or + removes buffer caches. If there are no files or buffers to remove + this is again a simple noop. - These functions, derived from BSD, are available in the separate -`libutil' library, and declared in `utmp.h'. + There normally is no return value different to NSS_STATUS_SUCCESS. - Note that the `ut_user' member of `struct utmp' is called `ut_name' -in BSD. Therefore, `ut_name' is defined as an alias for `ut_user' in -`utmp.h'. +`enum nss_status _nss_DATABASE_getDBent_r (STRUCTURE *result, char *buffer, size_t buflen, int *errnop)' + Since this function will be called several times in a row to + retrieve one entry after the other it must keep some kind of + state. But this also means the functions are not really + reentrant. They are reentrant only in that simultaneous calls to + this function will not try to write the retrieved data in the same + place (as it would be the case for the non-reentrant functions); + instead, it writes to the structure pointed to by the RESULT + parameter. But the calls share a common state and in the case of + a file access this means they return neighboring entries in the + file. - - Function: int login_tty (int FILEDES) - This function makes FILEDES the controlling terminal of the - current process, redirects standard input, standard output and - standard error output to this terminal, and closes FILEDES. + The buffer of length BUFLEN pointed to by BUFFER can be used for + storing some additional data for the result. It is _not_ + guaranteed that the same buffer will be passed for the next call + of this function. Therefore one must not misuse this buffer to + save some state information from one call to another. - This function returns `0' on successful completion, and `-1' on - error. + Before the function returns the implementation should store the + value of the local ERRNO variable in the variable pointed to be + ERRNOP. This is important to guarantee the module working in + statically linked programs. - - Function: void login (const struct utmp *ENTRY) - The `login' functions inserts an entry into the user accounting - database. The `ut_line' member is set to the name of the terminal - on standard input. If standard input is not a terminal `login' - uses standard output or standard error output to determine the - name of the terminal. If `struct utmp' has a `ut_type' member, - `login' sets it to `USER_PROCESS', and if there is an `ut_pid' - member, it will be set to the process ID of the current process. - The remaining entries are copied from ENTRY. + As explained above this function could also have an additional last + argument.

When `login' +starts running, its user ID is `root'. Its job is to start a shell +whose user and group IDs are those of the user who is logging in. (To +accomplish this fully, `login' must set the real user and group IDs as +well as its persona. But this is a special case.) + + The more common case of changing persona is when an ordinary user +program needs access to a resource that wouldn't ordinarily be +accessible to the user actually running it. + + For example, you may have a file that is controlled by your program +but that shouldn't be read or modified directly by other users, either +because it implements some kind of locking protocol, or because you want +to preserve the integrity or privacy of the information it contains. +This kind of restricted access can be implemented by having the program +change its effective user or group ID to match that of the resource. + + Thus, imagine a game program that saves scores in a file. The game +program itself needs to be able to update this file no matter who is +running it, but if users can write the file without going through the +game, they can give themselves any scores they like. Some people +consider this undesirable, or even reprehensible. It can be prevented +by creating a new user ID and login name (say, `games') to own the +scores file, and make the file writable only by this user. Then, when +the game program wants to update this file, it can change its effective +user ID to be that for `games'. In effect, the program must adopt the +persona of `games' so it can write the scores file.  -File: libc.info, Node: Scanning All Users, Next: Writing a User Entry, Prev: Lookup User, Up: User Database +File: libc.info, Node: How Change Persona, Next: Reading Persona, Prev: Why Change Persona, Up: Users and Groups -Scanning the List of All Users ------------------------------- +How an Application Can Change Persona +===================================== - This section explains how a program can read the list of all users in -the system, one user at a time. The functions described here are -declared in `pwd.h'. + The ability to change the persona of a process can be a source of +unintentional privacy violations, or even intentional abuse. Because of +the potential for problems, changing persona is restricted to special +circumstances. - You can use the `fgetpwent' function to read user entries from a -particular file. + You can't arbitrarily set your user ID or group ID to anything you +want; only privileged processes can do that. Instead, the normal way +for a program to change its persona is that it has been set up in +advance to change to a particular user or group. This is the function +of the setuid and setgid bits of a file's access mode. *Note +Permission Bits::. - - Function: struct passwd * fgetpwent (FILE *STREAM) - This function reads the next user entry from STREAM and returns a - pointer to the entry. The structure is statically allocated and is - rewritten on subsequent calls to `fgetpwent'. You must copy the - contents of the structure if you wish to save the information. + When the setuid bit of an executable file is on, executing that file +gives the process a third user ID: the "file user ID". This ID is set +to the owner ID of the file. The system then changes the effective +user ID to the file user ID. The real user ID remains as it was. +Likewise, if the setgid bit is on, the process is given a "file group +ID" equal to the group ID of the file, and its effective group ID is +changed to the file group ID. - The stream must correspond to a file in the same format as the - standard password database file. + If a process has a file ID (user or group), then it can at any time +change its effective ID to its real ID and back to its file ID. +Programs use this feature to relinquish their special privileges except +when they actually need them.

The functions described here are -declared in `grp.h'. + A typical setuid program does not need its special access all of the +time. It's a good idea to turn off this access when it isn't needed, +so it can't possibly give unintended access. - You can use the `fgetgrent' function to read group entries from a -particular file. + If the system supports the `_POSIX_SAVED_IDS' feature, you can +accomplish this with `seteuid'. When the game program starts, its real +user ID is `jdoe', its effective user ID is `games', and its saved user +ID is also `games'. The program should record both user ID values once +at the beginning, like this: - - Function: struct group * fgetgrent (FILE *STREAM) - The `fgetgrent' function reads the next entry from STREAM. It - returns a pointer to the entry. The structure is statically - allocated and is overwritten on subsequent calls to `fgetgrent'. - You must copy the contents of the structure if you wish to save the - information. + user_user_id = getuid (); + game_user_id = geteuid (); - The stream must correspond to a file in the same format as the - standard group database file. + Then it can turn off game file access with - - Function: int fgetgrent_r (FILE *STREAM, struct group *RESULT_BUF, - char *BUFFER, size_t BUFLEN, struct group **RESULT) - This function is similar to `fgetgrent' in that it reads the next - user entry from STREAM. But the result is returned in the - structure pointed to by RESULT_BUF. The first BUFLEN bytes of the - additional buffer pointed to by BUFFER are used to contain - additional information, normally strings which are pointed to by - the elements of the result structure. + seteuid (user_user_id); - This stream must correspond to a file in the same format as the - standard group database file. +and turn it on with - If the function returns zero RESULT points to the structure with - the wanted data (normally this is in RESULT_BUF). If errors - occurred the return value is non-zero and RESULT contains a null - pointer. + seteuid (game_user_id); - The way to scan all the entries in the group database is with -`setgrent', `getgrent', and `endgrent'. +Throughout this process, the real user ID remains `jdoe' and the file +user ID remains `games', so the program can always set its effective +user ID to either one. - - Function: void setgrent (void) - This function initializes a stream for reading from the group data - base. You use this stream by calling `getgrent' or `getgrent_r'. + On other systems that don't support file user IDs, you can turn +setuid access on and off by using `setreuid' to swap the real and +effective user IDs of the process, as follows: - - Function: struct group * getgrent (void) - The `getgrent' function reads the next entry from the stream - initialized by `setgrent'. It returns a pointer to the entry. The - structure is statically allocated and is overwritten on subsequent - calls to `getgrent'. You must copy the contents of the structure - if you wish to save the information. + setreuid (geteuid (), getuid ()); - - Function: int getgrent_r (struct group *RESULT_BUF, char *BUFFER, - size_t BUFLEN, struct group **RESULT) - This function is similar to `getgrent' in that it returns the next - entry from the stream initialized by `setgrent'. Like - `fgetgrent_r', it places the result in user-supplied buffers - pointed to RESULT_BUF and BUFFER. +This special case is always allowed--it cannot fail. - If the function returns zero RESULT contains a pointer to the data - (normally equal to RESULT_BUF). If errors occurred the return - value is non-zero and RESULT contains a null pointer. + Why does this have the effect of toggling the setuid access? +Suppose a game program has just started, and its real user ID is `jdoe' +while its effective user ID is `games'. In this state, the game can +write the scores file. If it swaps the two uids, the real becomes +`games' and the effective becomes `jdoe'; now the program has only +`jdoe' access. Another swap brings `games' back to the effective user +ID and restores access to the scores file. - - Function: void endgrent (void) - This function closes the internal stream used by `getgrent' or - `getgrent_r'. + In order to handle both kinds of systems, test for the saved user ID +feature with a preprocessor conditional, like this: + + #ifdef _POSIX_SAVED_IDS + setuid (user_user_id); + #else + setreuid (geteuid (), getuid ()); + #endif  -File: libc.info, Node: Database Example, Next: Netgroup Database, Prev: Group Database, Up: Users and Groups +File: libc.info, Node: Setuid Program Example, Next: Tips for Setuid, Prev: Enable/Disable Setuid, Up: Users and Groups -User and Group Database Example -=============================== +Setuid Program Example +====================== - Here is an example program showing the use of the system database -inquiry functions.

Don't let users of your program + execute arbitrary programs under a changed user ID. Executing a + shell is especially bad news. Less obviously, the `execlp' and + `execvp' functions are a potential risk (since the program they + execute depends on the user's `PATH' environment variable). - Sometimes it is useful to group users according to other criteria -(*note Group Database::). E.g., it is useful to associate a certain -group of users with a certain machine. On the other hand grouping of -host names is not supported so far. + If you must `exec' another program under a changed ID, specify an + absolute file name (*note File Name Resolution::) for the + executable, and make sure that the protections on that executable + and _all_ containing directories are such that ordinary users + cannot replace it with some other program. - In Sun Microsystems SunOS appeared a new kind of database, the -netgroup database. It allows grouping hosts, users, and domains -freely, giving them individual names. To be more concrete, a netgroup -is a list of triples consisting of a host name, a user name, and a -domain name where any of the entries can be a wildcard entry matching -all inputs. A last possibility is that names of other netgroups can -also be given in the list specifying a netgroup. So one can construct -arbitrary hierarchies without loops. + You should also check the arguments passed to the program to make + sure they do not have unexpected effects. Likewise, you should + examine the environment variables. Decide which arguments and + variables are safe, and reject all others. - Sun's implementation allows netgroups only for the `nis' or -`nisplus' service, *note Services in the NSS configuration::. The -implementation in the GNU C library has no such restriction.

Since a single netgroup can contain -many entries a two-step process is needed. First a single netgroup is -selected and then one can iterate over all entries in this netgroup. -These functions are declared in `netdb.h'. + You can use the functions listed in this section to determine the +login name of the user who is running a process, and the name of the +user who logged in the current session. See also the function `getuid' +and friends (*note Reading Persona::).

When the return value is `0' no - netgroup of this name is known or some other error occurred. + - Function: char * getlogin (void) + The `getlogin' function returns a pointer to a string containing + the name of the user logged in on the controlling terminal of the + process, or a null pointer if this information cannot be + determined. The string is statically allocated and might be + overwritten on subsequent calls to this function or to `cuserid'. - It is important to remember that there is only one single state for -iterating the netgroups. Even if the programmer uses the -`getnetgrent_r' function the result is not really reentrant since -always only one single netgroup at a time can be processed. If the -program needs to process more than one netgroup simultaneously she must -protect this by using external locking. This problem was introduced in -the original netgroups implementation in SunOS and since we must stay -compatible it is not possible to change this. + - Function: char * cuserid (char *STRING) + The `cuserid' function returns a pointer to a string containing a + user name associated with the effective ID of the process. If + STRING is not a null pointer, it should be an array that can hold + at least `L_cuserid' characters; the string is returned in this + array. Otherwise, a pointer to a string in a static area is + returned. This string is statically allocated and might be + overwritten on subsequent calls to this function or to `getlogin'. - Some other functions also use the netgroups state. Currently these -are the `innetgr' function and parts of the implementation of the -`compat' service part of the NSS implementation. + The use of this function is deprecated since it is marked to be + withdrawn in XPG4.2 and has already been removed from newer + revisions of POSIX.1. - - Function: int getnetgrent (char **HOSTP, char **USERP, char - **DOMAINP) - This function returns the next unprocessed entry of the currently - selected netgroup. The string pointers, in which addresses are - passed in the arguments HOSTP, USERP, and DOMAINP, will contain - after a successful call pointers to appropriate strings. If the - string in the next entry is empty the pointer has the value `NULL'. - The returned string pointers are only valid if none of the netgroup - related functions are called. + - Macro: int L_cuserid + An integer constant that indicates how long an array you might + need to store a user name. - The return value is `1' if the next entry was successfully read. A - value of `0' means no further entries exist or internal errors - occurred. + These functions let your program identify positively the user who is +running or the user who logged in this session.

The user +cannot do anything to fool these functions. - - Function: int getnetgrent_r (char **HOSTP, char **USERP, char - **DOMAINP, char *BUFFER, int BUFLEN) - This function is similar to `getnetgrent' with only one exception: - the strings the three string pointers HOSTP, USERP, and DOMAINP - point to, are placed in the buffer of BUFLEN bytes starting at - BUFFER.

First, let's review the various ways computer -systems are named, which is a little complicated because of the history -of the development of the Internet. + `int32_t ut_addr_v6[4]' + The Internet address of a remote host. - Every Unix system (also known as a host) has a host name, whether -it's connected to a network or not. In its simplest form, as used -before computer networks were an issue, it's just a word like `chicken'. + The `ut_type', `ut_pid', `ut_id', `ut_tv', and `ut_host' fields are +not available on all systems. Portable applications therefore should +be prepared for these situations. To help doing this the `utmp.h' +header provides macros `_HAVE_UT_TYPE', `_HAVE_UT_PID', `_HAVE_UT_ID', +`_HAVE_UT_TV', and `_HAVE_UT_HOST' if the respective field is +available. The programmer can handle the situations by using `#ifdef' +in the program code. - But any system attached to the Internet or any network like it -conforms to a more rigorous naming convention as part of the Domain -Name System (DNS). In DNS, every host name is composed of two parts: + The following macros are defined for use as values for the `ut_type' +member of the `utmp' structure. The values are integer constants. - 1. hostname +`EMPTY' + This macro is used to indicate that the entry contains no valid + user accounting information. - 2. domain name +`RUN_LVL' + This macro is used to identify the systems runlevel. - You will note that "hostname" looks a lot like "host name", but is -not the same thing, and that people often incorrectly refer to entire -host names as "domain names." +`BOOT_TIME' + This macro is used to identify the time of system boot. - In DNS, the full host name is properly called the FQDN (Fully -Qualified Domain Name) and consists of the hostname, then a period, -then the domain name. The domain name itself usually has multiple -components separated by periods. So for example, a system's hostname -may be `chicken' and its domain name might be `ai.mit.edu', so its FQDN -(which is its host name) is `chicken.ai.mit.edu'. +`OLD_TIME' + This macro is used to identify the time when the system clock + changed. - Adding to the confusion, though, is that DNS is not the only name -space in which a computer needs to be known. Another name space is the -NIS (aka YP) name space. For NIS purposes, there is another domain -name, which is called the NIS domain name or the YP domain name. It -need not have anything to do with the DNS domain name. +`NEW_TIME' + This macro is used to identify the time after the system changed. - Confusing things even more is the fact that in DNS, it is possible -for multiple FQDNs to refer to the same system. However, there is -always exactly one of them that is the true host name, and it is called -the canonical FQDN. +`INIT_PROCESS' + This macro is used to identify a process spawned by the init + process. - In some contexts, the host name is called a "node name." +`LOGIN_PROCESS' + This macro is used to identify the session leader of a logged in + user. - For more information on DNS host naming, *Note Host Names::. +`USER_PROCESS' + This macro is used to identify a user process. - Prototypes for these functions appear in `unistd.h'. +`DEAD_PROCESS' + This macro is used to identify a terminated process. - The programs `hostname', `hostid', and `domainname' work by calling -these functions. +`ACCOUNTING' + ??? - - Function: int gethostname (char *NAME, size_t SIZE) - This function returns the host name of the system on which it is - called, in the array NAME. The SIZE argument specifies the size of - this array, in bytes. Note that this is _not_ the DNS hostname. - If the system participates in DNS, this is the FQDN (see above). + The size of the `ut_line', `ut_id', `ut_user' and `ut_host' arrays +can be found using the `sizeof' operator. - The return value is `0' on success and `-1' on failure. In the - GNU C library, `gethostname' fails if SIZE is not large enough; - then you can try again with a larger array. The following `errno' - error condition is defined for this function: + Many older systems have, instead of an `ut_tv' member, an `ut_time' +member, usually of type `time_t', for representing the time associated +with the entry. Therefore, for backwards compatibility only, `utmp.h' +defines `ut_time' as an alias for `ut_tv.tv_sec'. - `ENAMETOOLONG' - The SIZE argument is less than the size of the host name plus - one. + - Function: void setutent (void) + This function opens the user accounting database to begin scanning + it. You can then call `getutent', `getutid' or `getutline' to + read entries and `pututline' to write entries. - On some systems, there is a symbol for the maximum possible host - name length: `MAXHOSTNAMELEN'. It is defined in `sys/param.h'. - But you can't count on this to exist, so it is cleaner to handle - failure and try again. + If the database is already open, it resets the input to the + beginning of the database. - `gethostname' stores the beginning of the host name in NAME even - if the host name won't entirely fit. For some purposes, a - truncated host name is good enough. If it is, you can ignore the - error code. + - Function: struct utmp * getutent (void) + The `getutent' function reads the next entry from the user + accounting database. It returns a pointer to the entry, which is + statically allocated and may be overwritten by subsequent calls to + `getutent'. You must copy the contents of the structure if you + wish to save the information or you can use the `getutent_r' + function which stores the data in a user-provided buffer. - - Function: int sethostname (const char *NAME, size_t LENGTH) - The `sethostname' function sets the host name of the system that - calls it to NAME, a string with length LENGTH. Only privileged - processes are permitted to do this. + A null pointer is returned in case no further entry is available. - Usually `sethostname' gets called just once, at system boot time. - Often, the program that calls it sets it to the value it finds in - the file `/etc/hostname'. + - Function: void endutent (void) + This function closes the user accounting database. - Be sure to set the host name to the full host name, not just the - DNS hostname (see above). + - Function: struct utmp * getutid (const struct utmp *ID) + This function searches forward from the current point in the + database for an entry that matches ID. If the `ut_type' member of + the ID structure is one of `RUN_LVL', `BOOT_TIME', `OLD_TIME' or + `NEW_TIME' the entries match if the `ut_type' members are + identical. If the `ut_type' member of the ID structure is + `INIT_PROCESS', `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS', + the entries match if the `ut_type' member of the entry read from + the database is one of these four, and the `ut_id' members match. + However if the `ut_id' member of either the ID structure or the + entry read from the database is empty it checks if the `ut_line' + members match instead. If a matching entry is found, `getutid' + returns a pointer to the entry, which is statically allocated, and + may be overwritten by a subsequent call to `getutent', `getutid' + or `getutline'. You must copy the contents of the structure if + you wish to save the information. - The return value is `0' on success and `-1' on failure. The - following `errno' error condition is defined for this function: + A null pointer is returned in case the end of the database is + reached without a match. - `EPERM' - This process cannot set the host name because it is not - privileged. + The `getutid' function may cache the last read entry. Therefore, + if you are using `getutid' to search for multiple occurrences, it + is necessary to zero out the static data after each call. + Otherwise `getutid' could just return a pointer to the same entry + over and over again. - - Function: int getdomainnname (char *NAME, size_t LENGTH) - `getdomainname' returns the NIS (aka YP) domain name of the system - on which it is called. Note that this is not the more popular DNS - domain name. Get that with `gethostname'. + - Function: struct utmp * getutline (const struct utmp *LINE) + This function searches forward from the current point in the + database until it finds an entry whose `ut_type' value is + `LOGIN_PROCESS' or `USER_PROCESS', and whose `ut_line' member + matches the `ut_line' member of the LINE structure. If it finds + such an entry, it returns a pointer to the entry which is + statically allocated, and may be overwritten by a subsequent call + to `getutent', `getutid' or `getutline'. You must copy the + contents of the structure if you wish to save the information. - The specifics of this function are analogous to `gethostname', - above. + A null pointer is returned in case the end of the database is + reached without a match. + The `getutline' function may cache the last read entry. Therefore + if you are using `getutline' to search for multiple occurrences, it + is necessary to zero out the static data after each call. + Otherwise `getutline' could just return a pointer to the same + entry over and over again. - - Function: int setdomainname (const char *NAME, size_t LENGTH) - `getdomainname' sets the NIS (aka YP) domain name of the system on - which it is called. Note that this is not the more popular DNS - domain name. Set that with `sethostname'. + - Function: struct utmp * pututline (const struct utmp *UTMP) + The `pututline' function inserts the entry `*UTMP' at the + appropriate place in the user accounting database. If it finds + that it is not already at the correct place in the database, it + uses `getutid' to search for the position to insert the entry, + however this will not modify the static structure returned by + `getutent', `getutid' and `getutline'. If this search fails, the + entry is appended to the database. - The specifics of this function are analogous to `sethostname', - above. + The `pututline' function returns a pointer to a copy of the entry + inserted in the user accounting database, or a null pointer if the + entry could not be added. The following `errno' error conditions + are defined for this function: + `EPERM' + The process does not have the appropriate privileges; you + cannot modify the user accounting database. - - Function: long int gethostid (void) - This function returns the "host ID" of the machine the program is - running on. By convention, this is usually the primary Internet - IP address of that machine, converted to a `long int'. However, - on some systems it is a meaningless but unique number which is - hard-coded for each machine. + All the `get*' functions mentioned before store the information they +return in a static buffer. This can be a problem in multi-threaded +programs since the data returned for the request is overwritten by the +return value data in another thread. Therefore the GNU C Library +provides as extensions three more functions which return the data in a +user-provided buffer. - This is not widely used. It arose in BSD 4.2, but was dropped in - BSD 4.4. It is not required by POSIX. + - Function: int getutent_r (struct utmp *BUFFER, struct utmp **RESULT) + The `getutent_r' is equivalent to the `getutent' function. It + returns the next entry from the database. But instead of storing + the information in a static buffer it stores it in the buffer + pointed to by the parameter BUFFER. - The proper way to query the IP address is to use `gethostbyname' - on the results of `gethostname'. For more information on IP - addresses, *Note Host Addresses::. + If the call was successful, the function returns `0' and the + pointer variable pointed to by the parameter RESULT contains a + pointer to the buffer which contains the result (this is most + probably the same value as BUFFER). If something went wrong + during the execution of `getutent_r' the function returns `-1'. - - Function: int sethostid (long int ID) - The `sethostid' function sets the "host ID" of the host machine to - ID. Only privileged processes are permitted to do this. Usually - it happens just once, at system boot time. + This function is a GNU extension. - The proper way to establish the primary IP address of a system is - to configure the IP address resolver to associate that IP address - with the system's host name as returned by `gethostname'. For - example, put a record for the system in `/etc/hosts'. + - Function: int getutid_r (const struct utmp *ID, struct utmp *BUFFER, + struct utmp **RESULT) + This function retrieves just like `getutid' the next entry matching + the information stored in ID. But the result is stored in the + buffer pointed to by the parameter BUFFER. - See `gethostid' above for more information on host ids. + If successful the function returns `0' and the pointer variable + pointed to by the parameter RESULT contains a pointer to the + buffer with the result (probably the same as RESULT. If not + successful the function return `-1'. - The return value is `0' on success and `-1' on failure. The - following `errno' error conditions are defined for this function: + This function is a GNU extension. - `EPERM' - This process cannot set the host name because it is not - privileged. + - Function: int getutline_r (const struct utmp *LINE, struct utmp + *BUFFER, struct utmp **RESULT) + This function retrieves just like `getutline' the next entry + matching the information stored in LINE. But the result is stored + in the buffer pointed to by the parameter BUFFER. - `ENOSYS' - The operating system does not support setting the host ID. - On some systems, the host ID is a meaningless but unique - number hard-coded for each machine. + If successful the function returns `0' and the pointer variable + pointed to by the parameter RESULT contains a pointer to the + buffer with the result (probably the same as RESULT. If not + successful the function return `-1'. - -File: libc.info, Node: Platform Type, Next: Filesystem Handling, Prev: Host Identification, Up: System Management + This function is a GNU extension. -Platform Type Identification -============================ + In addition to the user accounting database, most systems keep a +number of similar databases. For example most systems keep a log file +with all previous logins (usually in `/etc/wtmp' or `/var/log/wtmp'). - You can use the `uname' function to find out some information about -the type of computer your program is running on. This function and the -associated data type are declared in the header file `sys/utsname.h'. + For specifying which database to examine, the following function +should be used. - As a bonus, `uname' also gives some information identifying the -particular system your program is running on. This is the same -information which you can get with functions targetted to this purpose -described in *Note Host Identification::. + - Function: int utmpname (const char *FILE) + The `utmpname' function changes the name of the database to be + examined to FILE, and closes any previously opened database. By + default `getutent', `getutid', `getutline' and `pututline' read + from and write to the user accounting database. - - Data Type: struct utsname - The `utsname' structure is used to hold information returned by - the `uname' function. It has the following members: + The following macros are defined for use as the FILE argument: - `char sysname[]' - This is the name of the operating system in use. + - Macro: char * _PATH_UTMP + This macro is used to specify the user accounting database. - `char release[]' - This is the current release level of the operating system - implementation. + - Macro: char * _PATH_WTMP + This macro is used to specify the user accounting log file. - `char version[]' - This is the current version level within the release of the - operating system. + The `utmpname' function returns a value of `0' if the new name was + successfully stored, and a value of `-1' to indicate an error. + Note that `utmpname' does not try to open the database, and that + therefore the return value does not say anything about whether the + database can be successfully opened. - `char machine[]' - This is a description of the type of hardware that is in use. + Specially for maintaining log-like databases the GNU C Library +provides the following function: - Some systems provide a mechanism to interrogate the kernel - directly for this information. On systems without such a - mechanism, the GNU C library fills in this field based on the - configuration name that was specified when building and - installing the library. + - Function: void updwtmp (const char *WTMP_FILE, const struct utmp + *UTMP) + The `updwtmp' function appends the entry *UTMP to the database + specified by WTMP_FILE. For possible values for the WTMP_FILE + argument see the `utmpname' function. - GNU uses a three-part name to describe a system - configuration; the three parts are CPU, MANUFACTURER and - SYSTEM-TYPE, and they are separated with dashes. Any - possible combination of three names is potentially - meaningful, but most such combinations are meaningless in - practice and even the meaningful ones are not necessarily - supported by any particular GNU program. + *Portability Note:* Although many operating systems provide a subset +of these functions, they are not standardized. There are often subtle +differences in the return types, and there are considerable differences +between the various definitions of `struct utmp'. When programming for +the GNU system, it is probably best to stick with the functions +described in this section. If however, you want your program to be +portable, consider using the XPG functions described in *Note XPG +Functions::, or take a look at the BSD compatible functions in *Note +Logging In and Out::. - Since the value in `machine' is supposed to describe just the - hardware, it consists of the first two parts of the - configuration name: `CPU-MANUFACTURER'. For example, it - might be one of these: + +File: libc.info, Node: XPG Functions, Next: Logging In and Out, Prev: Manipulating the Database, Up: User Accounting Database - `"sparc-sun"', `"i386-ANYTHING"', `"m68k-hp"', - `"m68k-sony"', `"m68k-sun"', `"mips-dec"' +XPG User Accounting Database Functions +-------------------------------------- - `char nodename[]' - This is the host name of this particular computer. In the - GNU C library, the value is the same as that returned by - `gethostname'; see *Note Host Identification::. + These functions, described in the X/Open Portability Guide, are +declared in the header file `utmpx.h'. - gethostname() is implemented with a call to uname(). + - Data Type: struct utmpx + The `utmpx' data structure contains at least the following members: - `char domainname[]' - This is the NIS or YP domain name. It is the same value - returned by `getdomainname'; see *Note Host Identification::. - This element is a relatively recent invention and use of it - is not as portable as use of the rest of the structure. + `short int ut_type' + Specifies the type of login; one of `EMPTY', `RUN_LVL', + `BOOT_TIME', `OLD_TIME', `NEW_TIME', `INIT_PROCESS', + `LOGIN_PROCESS', `USER_PROCESS' or `DEAD_PROCESS'. + `pid_t ut_pid' + The process ID number of the login process. - - Function: int uname (struct utsname *INFO) - The `uname' function fills in the structure pointed to by INFO - with information about the operating system and host machine. A - non-negative value indicates that the data was successfully stored. + `char ut_line[]' + The device name of the tty (without `/dev/'). - `-1' as the value indicates an error. The only error possible is - `EFAULT', which we normally don't mention as it is always a - possibility. + `char ut_id[]' + The inittab ID of the process. - -File: libc.info, Node: Filesystem Handling, Next: System Parameters, Prev: Platform Type, Up: System Management + `char ut_user[]' + The user's login name. -Controlling and Querying Mounts -=============================== + `struct timeval ut_tv' + Time the entry was made. For entries of type `OLD_TIME' this + is the time when the system clock changed, and for entries of + type `NEW_TIME' this is the time the system clock was set to. + On the GNU system, `struct utmpx' is identical to `struct utmp' + except for the fact that including `utmpx.h' does not make visible + the declaration of `struct exit_status'. - All files are in filesystems, and before you can access any file, its -filesystem must be mounted. Because of Unix's concept of _Everything -is a file_, mounting of filesystems is central to doing almost -anything. This section explains how to find out what filesystems are -currently mounted and what filesystems are available for mounting, and -how to change what is mounted. + The following macros are defined for use as values for the `ut_type' +member of the `utmpx' structure. The values are integer constants and +are, on the GNU system, identical to the definitions in `utmp.h'. - The classic filesystem is the contents of a disk drive. The concept -is considerably more abstract, though, and lots of things other than -disk drives can be mounted. +`EMPTY' + This macro is used to indicate that the entry contains no valid + user accounting information. - Some block devices don't correspond to traditional devices like disk -drives. For example, a loop device is a block device whose driver uses -a regular file in another filesystem as its medium. So if that regular -file contains appropriate data for a filesystem, you can by mounting the -loop device essentially mount a regular file. +`RUN_LVL' + This macro is used to identify the systems runlevel. - Some filesystems aren't based on a device of any kind. The "proc" -filesystem, for example, contains files whose data is made up by the -filesystem driver on the fly whenever you ask for it. And when you -write to it, the data you write causes changes in the system. No data -gets stored. +`BOOT_TIME' + This macro is used to identify the time of system boot. -* Menu: +`OLD_TIME' + This macro is used to identify the time when the system clock + changed. -* Mount Information:: What is or could be mounted? -* Mount-Unmount-Remount:: Controlling what is mounted and how +`NEW_TIME' + This macro is used to identify the time after the system changed. - -File: libc.info, Node: Mount Information, Next: Mount-Unmount-Remount, Up: Filesystem Handling +`INIT_PROCESS' + This macro is used to identify a process spawned by the init + process. -Mount Information ------------------ +`LOGIN_PROCESS' + This macro is used to identify the session leader of a logged in + user. - For some programs it is desirable and necessary to access information -about whether a certain filesystem is mounted and, if it is, where, or -simply to get lists of all the available filesystems. The GNU libc -provides some functions to retrieve this information portably. +`USER_PROCESS' + This macro is used to identify a user process. - Traditionally Unix systems have a file named `/etc/fstab' which -describes all possibly mounted filesystems. The `mount' program uses -this file to mount at startup time of the system all the necessary -filesystems. The information about all the filesystems actually mounted -is normally kept in a file named `/etc/mtab'. Both files share the -same syntax and it is crucial that this syntax is followed all the -time. Therefore it is best to never directly write the files. The -functions described in this section can do this and they also provide -the functionality to convert the external textual representation to the -internal representation. +`DEAD_PROCESS' + This macro is used to identify a terminated process. - Note that the `fstab' and `mtab' files are maintained on a system by -_convention_. It is possible for the files not to exist or not to be -consistent with what is really mounted or available to mount, if the -system's administration policy allows it. But programs that mount and -unmount filesystems typically maintain and use these files as described -herein. + The size of the `ut_line', `ut_id' and `ut_user' arrays can be found +using the `sizeof' operator. - The filenames given above should never be used directly. The -portable way to handle these file is to use the macros `_PATH_FSTAB', -defined in `fstab.h' and `_PATH_MNTTAB', defined in `mntent.h', -respectively. There are also two alternate macro names `FSTAB' and -`_PATH_MOUNTED' defined but both names are deprecated and kept only for -backward compatibility. The two former names should always be used. + - Function: void setutxent (void) + This function is similar to `setutent'. On the GNU system it is + simply an alias for `setutent'. -* Menu: + - Function: struct utmpx * getutxent (void) + The `getutxent' function is similar to `getutent', but returns a + pointer to a `struct utmpx' instead of `struct utmp'.

On the GNU system it is simply an alias + for `getutid'. -The `fstab' file -................ + - Function: struct utmpx * getutxline (const struct utmpx *LINE) + This function is similar to `getutid', but uses `struct utmpx' + instead of `struct utmp'. On the GNU system it is simply an alias + for `getutline'. - The internal representation for entries of the file is -`struct fstab', defined in `fstab.h'. + - Function: struct utmpx * pututxline (const struct utmpx *UTMP) + The `pututxline' function is functionally identical to + `pututline', but uses `struct utmpx' instead of `struct utmp'. On + the GNU system, `pututxline' is simply an alias for `pututline'. - - Data Type: struct fstab - This structure is used with the `getfsent', `getfsspec', and - `getfsfile' functions. + - Function: int utmpxname (const char *FILE) + The `utmpxname' function is functionally identical to `utmpname'. + On the GNU system, `utmpxname' is simply an alias for `utmpname'. - `char *fs_spec' - This element describes the device from which the filesystem - is mounted. Normally this is the name of a special device, - such as a hard disk partition, but it could also be a more or - less generic string. For "NFS" it would be a hostname and - directory name combination. + You can translate between a traditional `struct utmp' and an XPG +`struct utmpx' with the following functions. On the GNU system, these +functions are merely copies, since the two structures are identical. - Even though the element is not declared `const' it shouldn't - be modified. The missing `const' has historic reasons, since - this function predates ISO C. The same is true for the other - string elements of this structure. + - Function: int getutmp (const struct utmpx *utmpx, struct utmp *utmp) + `getutmp' copies the information, insofar as the structures are + compatible, from UTMPX to UTMP. - `char *fs_file' - This describes the mount point on the local system. I.e., - accessing any file in this filesystem has implicitly or - explicitly this string as a prefix. + - Function: int getutmpx (const struct utmp *utmp, struct utmpx *utmpx) + `getutmpx' copies the information, insofar as the structures are + compatible, from UTMP to UTMPX. - `char *fs_vfstype' - This is the type of the filesystem. Depending on what the - underlying kernel understands it can be any string. + +File: libc.info, Node: Logging In and Out, Prev: XPG Functions, Up: User Accounting Database - `char *fs_mntops' - This is a string containing options passed to the kernel with - the `mount' call. Again, this can be almost anything. There - can be more than one option, separated from the others by a - comma. Each option consists of a name and an optional value - part, introduced by an `=' character. +Logging In and Out +------------------ - If the value of this element must be processed it should - ideally be done using the `getsubopt' function; see *Note - Suboptions::. + These functions, derived from BSD, are available in the separate +`libutil' library, and declared in `utmp.h'. - `const char *fs_type' - This name is poorly chosen. This element points to a string - (possibly in the `fs_mntops' string) which describes the - modes with which the filesystem is mounted. `fstab' defines - five macros to describe the possible values: + Note that the `ut_user' member of `struct utmp' is called `ut_name' +in BSD. Therefore, `ut_name' is defined as an alias for `ut_user' in +`utmp.h'. - `FSTAB_RW' - The filesystems gets mounted with read and write enabled. + - Function: int login_tty (int FILEDES) + This function makes FILEDES the controlling terminal of the + current process, redirects standard input, standard output and + standard error output to this terminal, and closes FILEDES. - `FSTAB_RQ' - The filesystems gets mounted with read and write - enabled. Write access is restricted by quotas. + This function returns `0' on successful completion, and `-1' on + error. - `FSTAB_RO' - The filesystem gets mounted read-only. + - Function: void login (const struct utmp *ENTRY) + The `login' functions inserts an entry into the user accounting + database. The `ut_line' member is set to the name of the terminal + on standard input. If standard input is not a terminal `login' + uses standard output or standard error output to determine the + name of the terminal. If `struct utmp' has a `ut_type' member, + `login' sets it to `USER_PROCESS', and if there is an `ut_pid' + member, it will be set to the process ID of the current process. + The remaining entries are copied from ENTRY. - `FSTAB_SW' - This is not a real filesystem, it is a swap device. + A copy of the entry is written to the user accounting log file. - `FSTAB_XX' - This entry from the `fstab' file is totally ignored. + - Function: int logout (const char *UT_LINE) + This function modifies the user accounting database to indicate + that the user on UT_LINE has logged out. - Testing for equality with these value must happen using - `strcmp' since these are all strings. Comparing the pointer - will probably always fail. + The `logout' function returns `1' if the entry was successfully + written to the database, or `0' on error. - `int fs_freq' - This element describes the dump frequency in days. + - Function: void logwtmp (const char *UT_LINE, const char *UT_NAME, + const char *UT_HOST) + The `logwtmp' function appends an entry to the user accounting log + file, for the current time and the information provided in the + UT_LINE, UT_NAME and UT_HOST arguments. - `int fs_passno' - This element describes the pass number on parallel dumps. It - is closely related to the `dump' utility used on Unix systems. + *Portability Note:* The BSD `struct utmp' only has the `ut_line', +`ut_name', `ut_host' and `ut_time' members.

This is done by - either opening the file or resetting the read pointer. +User Database +============= - Since the file handle is internal to the libc this function is not - thread-safe. + This section describes how to search and scan the database of +registered users. The database itself is kept in the file +`/etc/passwd' on most systems, but on some systems a special network +server gives access to it. - This function returns a non-zero value if the operation was - successful and the `getfs*' functions can be used to read the - entries of the file. +* Menu: - - Function: void endfsent (void) - This function makes sure that all resources acquired by a prior - call to `setfsent' (explicitly or implicitly by calling - `getfsent') are freed. +* User Data Structure:: What each user record contains. +* Lookup User:: How to look for a particular user. +* Scanning All Users:: Scanning the list of all users, one by one. +* Writing a User Entry:: How a program can rewrite a user's record. - - Function: struct fstab * getfsent (void) - This function returns the next entry of the `fstab' file.

It corresponds to the `fs_spec' element in `struct - fstab'. - - `char *mnt_dir' - This element points to a string describing the mount point of - the filesystem. It corresponds to the `fs_file' element in - `struct fstab'. - - `char *mnt_type' - `mnt_type' describes the filesystem type and is therefore - equivalent to `fs_vfstype' in `struct fstab'. `mntent.h' - defines a few symbolic names for some of the values this - string can have. But since the kernel can support arbitrary - filesystems it does not make much sense to give them symbolic - names. If one knows the symbol name one also knows the - filesystem name. Nevertheless here follows the list of the - symbols provided in `mntent.h'. - - `MNTTYPE_IGNORE' - This symbol expands to `"ignore"'. The value is - sometime used in `fstab' files to make sure entries are - not used without removing them. - - `MNTTYPE_NFS' - Expands to `"nfs"'. Using this macro sometimes could - make sense since it names the default NFS - implementation, in case both version 2 and 3 are - supported. - - `MNTTYPE_SWAP' - This symbol expands to `"swap"'. It names the special - `fstab' entry which names one of the possibly multiple - swap partitions. - - `char *mnt_opts' - The element contains a string describing the options used - while mounting the filesystem. As for the equivalent element - `fs_mntops' of `struct fstab' it is best to use the function - `getsubopt' (*note Suboptions::) to access the parts of this - string. - - The `mntent.h' file defines a number of macros with string - values which correspond to some of the options understood by - the kernel. There might be many more options which are - possible so it doesn't make much sense to rely on these - macros but to be consistent here is the list: - - `MNTOPT_DEFAULTS' - Expands to `"defaults"'. This option should be used - alone since it indicates all values for the customizable - values are chosen to be the default. - - `MNTOPT_RO' - Expands to `"ro"'. See the `FSTAB_RO' value, it means - the filesystem is mounted read-only. - - `MNTOPT_RW' - Expand to `"rw"'. See the `FSTAB_RW' value, it means the - filesystem is mounted with read and write permissions. - - `MNTOPT_SUID' - Expands to `"suid"'. This means that the SUID bit - (*note How Change Persona::) is respected when a program - from the filesystem is started. - - `MNTOPT_NOSUID' - Expands to `"nosuid"'. This is the opposite of - `MNTOPT_SUID', the SUID bit for all files from the - filesystem is ignored. - - `MNTOPT_NOAUTO' - Expands to `"noauto"'. At startup time the `mount' - program will ignore this entry if it is started with the - `-a' option to mount all filesystems mentioned in the - `fstab' file. - - As for the `FSTAB_*' entries introduced above it is important - to use `strcmp' to check for equality. - - `mnt_freq' - This elements corresponds to `fs_freq' and also specifies the - frequency in days in which dumps are made. - - `mnt_passno' - This element is equivalent to `fs_passno' with the same - meaning which is uninteresting for all programs beside `dump'. - - For accessing the `mtab' file there is again a set of three -functions to access all entries in a row. Unlike the functions to -handle `fstab' these functions do not access a fixed file and there is -even a thread safe variant of the get function. Beside this the GNU -libc contains functions to alter the file and test for specific options. - - - Function: FILE * setmntent (const char *FILE, const char *MODE) - The `setmntent' function prepares the file named FILE which must - be in the format of a `fstab' and `mtab' file for the upcoming - processing through the other functions of the family. The MODE - parameter can be chosen in the way the OPENTYPE parameter for - `fopen' (*note Opening Streams::) can be chosen. If the file is - opened for writing the file is also allowed to be empty. - - If the file was successfully opened `setmntent' returns a file - descriptor for future use. Otherwise the return value is `NULL' - and `errno' is set accordingly. - - - Function: int endmntent (FILE *STREAM) - This function takes for the STREAM parameter a file handle which - previously was returned from the `setmntent' call. `endmntent' - closes the stream and frees all resources. - - The return value is 1 unless an error occurred in which case it is - 0. - - - Function: struct mntent * getmntent (FILE *STREAM) - The `getmntent' function takes as the parameter a file handle - previously returned by successful call to `setmntent'. It returns - a pointer to a static variable of type `struct mntent' which is - filled with the information from the next entry from the file - currently read. - - The file format used prescribes the use of spaces or tab - characters to separate the fields. This makes it harder to use - name containing one of these characters (e.g., mount points using - spaces). Therefore these characters are encoded in the files and - the `getmntent' function takes care of the decoding while reading - the entries back in. `'\040'' is used to encode a space - character, `'\012'' to encode a tab character and `'\\'' to encode - a backslash. - - If there was an error or the end of the file is reached the return - value is `NULL'. - - This function is not thread-safe since all calls to this function - return a pointer to the same static variable. `getmntent_r' - should be used in situations where multiple threads access the - file. - - - Function: struct mntent * getmntent_r (FILE *STREAM, struct mentent - *RESULT, char *BUFFER, int BUFSIZE) - The `getmntent_r' function is the reentrant variant of - `getmntent'. It also returns the next entry from the file and - returns a pointer. The actual variable the values are stored in - is not static, though. Instead the function stores the values in - the variable pointed to by the RESULT parameter. Additional - information (e.g., the strings pointed to by the elements of the - result) are kept in the buffer of size BUFSIZE pointed to by - BUFFER. - - Escaped characters (space, tab, backslash) are converted back in - the same way as it happens for `getmentent'. - - The function returns a `NULL' pointer in error cases.

The first + BUFLEN bytes of the additional buffer pointed to by BUFFER are + used to contain additional information, normally strings which are + pointed to by the elements of the result structure. - - Function: char * hasmntopt (const struct mntent *MNT, const char - *OPT) - This function can be used to check whether the string pointed to - by the `mnt_opts' element of the variable pointed to by MNT - contains the option OPT. If this is true a pointer to the - beginning of the option in the `mnt_opts' element is returned. If - no such option exists the function returns `NULL'. + If a user with ID UID is found, the pointer returned in RESULT + points to the record which contains the wanted data (i.e., RESULT + contains the value RESULT_BUF).

If the buffer BUFFER + is too small to contain all the needed information, the error code + `ERANGE' is returned and ERRNO is set to `ERANGE'. - This function is useful to test whether a specific option is - present but when all options have to be processed one is better - off with using the `getsubopt' function to iterate over all - options in the string. + - Function: struct passwd * getpwnam (const char *NAME) + This function returns a pointer to a statically-allocated structure + containing information about the user whose user name is NAME. + This structure may be overwritten on subsequent calls to + `getpwnam'. - -File: libc.info, Node: Other Mount Information, Prev: mtab, Up: Mount Information + A null pointer return indicates there is no user named NAME. -Other (Non-libc) Sources of Mount Information -............................................. + - Function: int getpwnam_r (const char *NAME, struct passwd + *RESULT_BUF, char *BUFFER, size_t BUFLEN, struct passwd + **RESULT) + This function is similar to `getpwnam' in that is returns + information about the user whose user name is NAME.

You -should maintain and use these separately. *Note Mount Information::. - - The symbols in this section are declared in `sys/mount.h'. - - - Function: int mount (const char *SPECIAL_FILE, const char *DIR, - const char *FSTYPE, unsigned long int OPTIONS, const void - *DATA) - `mount' mounts or remounts a filesystem. The two operations are - quite different and are merged rather unnaturally into this one - function. The `MS_REMOUNT' option, explained below, determines - whether `mount' mounts or remounts. - - For a mount, the filesystem on the block device represented by the - device special file named SPECIAL_FILE gets mounted over the mount - point DIR. This means that the directory DIR (along with any - files in it) is no longer visible; in its place (and still with - the name DIR) is the root directory of the filesystem on the - device. - - As an exception, if the filesystem type (see below) is one which - is not based on a device (e.g. "proc"), `mount' instantiates a - filesystem and mounts it over DIR and ignores SPECIAL_FILE. - - For a remount, DIR specifies the mount point where the filesystem - to be remounted is (and remains) mounted and SPECIAL_FILE is - ignored. Remounting a filesystem means changing the options that - control operations on the filesystem while it is mounted. It does - not mean unmounting and mounting again. - - For a mount, you must identify the type of the filesystem as - FSTYPE. This type tells the kernel how to access the filesystem - and can be thought of as the name of a filesystem driver. The - acceptable values are system dependent. On a system with a Linux - kernel and the `proc' filesystem, the list of possible values is - in the file `filesystems' in the `proc' filesystem (e.g. type `cat - /proc/filesystems' to see the list). With a Linux kernel, the - types of filesystems that `mount' can mount, and their type names, - depends on what filesystem drivers are configured into the kernel - or loaded as loadable kernel modules. An example of a common - value for FSTYPE is `ext2'. - - For a remount, `mount' ignores FSTYPE. - - OPTIONS specifies a variety of options that apply until the - filesystem is unmounted or remounted. The precise meaning of an - option depends on the filesystem and with some filesystems, an - option may have no effect at all. Furthermore, for some - filesystems, some of these options (but never `MS_RDONLY') can be - overridden for individual file accesses via `ioctl'. - - OPTIONS is a bit string with bit fields defined using the - following mask and masked value macros: - - `MS_MGC_MASK' - This multibit field contains a magic number. If it does not - have the value `MS_MGC_VAL', `mount' assumes all the - following bits are zero and the DATA argument is a null - string, regardless of their actual values. - - `MS_REMOUNT' - This bit on means to remount the filesystem. Off means to - mount it. - - `MS_RDONLY' - This bit on specifies that no writing to the filesystem shall - be allowed while it is mounted. This cannot be overridden by - `ioctl'. This option is available on nearly all filesystems. - - `S_IMMUTABLE' - This bit on specifies that no writing to the files in the - filesystem shall be allowed while it is mounted. This can be - overridden for a particular file access by a properly - privileged call to `ioctl'. This option is a relatively new - invention and is not available on many filesystems. - - `S_APPEND' - This bit on specifies that the only file writing that shall - be allowed while the filesystem is mounted is appending. - Some filesystems allow this to be overridden for a particular - process by a properly privileged call to `ioctl'. This is a - relatively new invention and is not available on many - filesystems. - - `MS_NOSUID' - This bit on specifies that Setuid and Setgid permissions on - files in the filesystem shall be ignored while it is mounted. - - `MS_NOEXEC' - This bit on specifies that no files in the filesystem shall - be executed while the filesystem is mounted. - - `MS_NODEV' - This bit on specifies that no device special files in the - filesystem shall be accessible while the filesystem is - mounted. - - `MS_SYNCHRONOUS' - This bit on specifies that all writes to the filesystem while - it is mounted shall be synchronous; i.e. data shall be synced - before each write completes rather than held in the buffer - cache. - - `MS_MANDLOCK' - This bit on specifies that mandatory locks on files shall be - permitted while the filesystem is mounted. - - `MS_NOATIME' - This bit on specifies that access times of files shall not be - updated when the files are accessed while the filesystem is - mounted. - - `MS_NODIRATIME' - This bit on specifies that access times of directories shall - not be updated when the directories are accessed while the - filesystem in mounted. - - Any bits not covered by the above masks should be set off; - otherwise, results are undefined. - - The meaning of DATA depends on the filesystem type and is - controlled entirely by the filesystem driver in the kernel. - - Example: +File: libc.info, Node: Scanning All Users, Next: Writing a User Entry, Prev: Lookup User, Up: User Database - #include - - mount("/dev/hdb", "/cdrom", MS_MGC_VAL | MS_RDONLY | MS_NOSUID, ""); - - mount("/dev/hda2", "/mnt", MS_MGC_VAL | MS_REMOUNT, ""); +Scanning the List of All Users +------------------------------ - Appropriate arguments for `mount' are conventionally recorded in - the `fstab' table. *Note Mount Information::. + This section explains how a program can read the list of all users in +the system, one user at a time.

If you don't want to set the - parameter, specify a null pointer as NEWVAL. + - Function: struct group * fgetgrent (FILE *STREAM) + The `fgetgrent' function reads the next entry from STREAM. It + returns a pointer to the entry. The structure is statically + allocated and is overwritten on subsequent calls to `fgetgrent'. + You must copy the contents of the structure if you wish to save the + information. - If you get and set a parameter in the same `sysctl' call, the value - returned is the value of the parameter before it was set. + The stream must correspond to a file in the same format as the + standard group database file. - Each system parameter has a set of permissions similar to the - permissions for a file (including the permissions on directories - in its path) that determine whether you may get or set it. For - the purposes of these permissions, every parameter is considered - to be owned by the superuser and Group 0 so processes with that - effective uid or gid may have more access to system parameters. - Unlike with files, the superuser does not invariably have full - permission to all system parameters, because some of them are - designed not to be changed ever. + - Function: int fgetgrent_r (FILE *STREAM, struct group *RESULT_BUF, + char *BUFFER, size_t BUFLEN, struct group **RESULT) + This function is similar to `fgetgrent' in that it reads the next + user entry from STREAM. But the result is returned in the + structure pointed to by RESULT_BUF. The first BUFLEN bytes of the + additional buffer pointed to by BUFFER are used to contain + additional information, normally strings which are pointed to by + the elements of the result structure. - `sysctl' returns a zero return value if it succeeds. Otherwise, it - returns `-1' and sets `errno' appropriately. Besides the failures - that apply to all system calls, the following are the `errno' - codes for all possible failures: + This stream must correspond to a file in the same format as the + standard group database file. - `EPERM' - The process is not permitted to access one of the components - of the path of the system parameter or is not permitted to - access the system parameter itself in the way (read or write) - that it requested. + If the function returns zero RESULT points to the structure with + the wanted data (normally this is in RESULT_BUF). If errors + occurred the return value is non-zero and RESULT contains a null + pointer. - `ENOTDIR' - There is no system parameter corresponding to NAME. + The way to scan all the entries in the group database is with +`setgrent', `getgrent', and `endgrent'. - `EFAULT' - OLDVAL is not null, which means the process wanted to read - the parameter, but *OLDLENP is zero, so there is no place to - return it. + - Function: void setgrent (void) + This function initializes a stream for reading from the group data + base. You use this stream by calling `getgrent' or `getgrent_r'. - `EINVAL' - * The process attempted to set a system parameter to a - value that is not valid for that parameter. + - Function: struct group * getgrent (void) + The `getgrent' function reads the next entry from the stream + initialized by `setgrent'. It returns a pointer to the entry. The + structure is statically allocated and is overwritten on subsequent + calls to `getgrent'. You must copy the contents of the structure + if you wish to save the information. - * The space provided for the return of the system - parameter is not the right size for that parameter. + - Function: int getgrent_r (struct group *RESULT_BUF, char *BUFFER, + size_t BUFLEN, struct group **RESULT) + This function is similar to `getgrent' in that it returns the next + entry from the stream initialized by `setgrent'. Like + `fgetgrent_r', it places the result in user-supplied buffers + pointed to RESULT_BUF and BUFFER. - `ENOMEM' - This value may be returned instead of the more correct - `EINVAL' in some cases where the space provided for the - return of the system parameter is too small. + If the function returns zero RESULT contains a pointer to the data + (normally equal to RESULT_BUF). If errors occurred the return + value is non-zero and RESULT contains a null pointer. + - Function: void endgrent (void) + This function closes the internal stream used by `getgrent' or + `getgrent_r'. - If you have a Linux kernel with the `proc' filesystem, you can get -and set most of the same parameters by reading and writing to files in -the `sys' directory of the `proc' filesystem. In the `sys' directory, -the directory structure represents the hierarchical structure of the -parameters.

If the system allows different file systems or -files to have different limits, then the macro is undefined; use -`sysconf' to find out the limit that applies at a particular time on a -particular machine. *Note Sysconf::. - - Each of these parameters also has another macro, with a name starting -with `_POSIX', which gives the lowest value that the limit is allowed -to have on _any_ POSIX system. *Note Minimums::. - - - Macro: int ARG_MAX - If defined, the unvarying maximum combined length of the ARGV and - ENVIRON arguments that can be passed to the `exec' functions. - - - Macro: int CHILD_MAX - If defined, the unvarying maximum number of processes that can - exist with the same real user ID at any one time.

E.g., it is useful to associate a certain +group of users with a certain machine. On the other hand grouping of +host names is not supported so far. - This macro is defined in all POSIX systems because this limit is - never configurable. + In Sun Microsystems SunOS appeared a new kind of database, the +netgroup database. It allows grouping hosts, users, and domains +freely, giving them individual names. To be more concrete, a netgroup +is a list of triples consisting of a host name, a user name, and a +domain name where any of the entries can be a wildcard entry matching +all inputs. A last possibility is that names of other netgroups can +also be given in the list specifying a netgroup. So one can construct +arbitrary hierarchies without loops. - - Macro: int RE_DUP_MAX - The largest number of repetitions you are guaranteed is allowed in - the construct `\{MIN,MAX\}' in a regular expression. + Sun's implementation allows netgroups only for the `nis' or +`nisplus' service, *note Services in the NSS configuration::. The +implementation in the GNU C library has no such restriction. An entry +in either of the input services must have the following form: - The value of this macro is actually a lower bound for the maximum. - That is, you can count on being able to have that many - repetitions, but a particular machine might let you have even - more.

Since these options are provided in the kernel, not -in the library, simply using the GNU C library does not guarantee any -of these features is supported; it depends on the system you are using. + The lookup functions for netgroups are a bit different to all other +system database handling functions. Since a single netgroup can contain +many entries a two-step process is needed. First a single netgroup is +selected and then one can iterate over all entries in this netgroup. +These functions are declared in `netdb.h'. - You can test for the availability of a given option using the macros -in this section, together with the function `sysconf'. The macros are -defined only if you include `unistd.h'. + - Function: int setnetgrent (const char *NETGROUP) + A call to this function initializes the internal state of the + library to allow following calls of the `getnetgrent' to iterate + over all entries in the netgroup with name NETGROUP. - For the following macros, if the macro is defined in `unistd.h', -then the option is supported. Otherwise, the option may or may not be -supported; use `sysconf' to find out. *Note Sysconf::. + When the call is successful (i.e., when a netgroup with this name + exists) the return value is `1'. When the return value is `0' no + netgroup of this name is known or some other error occurred. - - Macro: int _POSIX_JOB_CONTROL - If this symbol is defined, it indicates that the system supports - job control. Otherwise, the implementation behaves as if all - processes within a session belong to a single process group. - *Note Job Control::. + It is important to remember that there is only one single state for +iterating the netgroups. Even if the programmer uses the +`getnetgrent_r' function the result is not really reentrant since +always only one single netgroup at a time can be processed. If the +program needs to process more than one netgroup simultaneously she must +protect this by using external locking. This problem was introduced in +the original netgroups implementation in SunOS and since we must stay +compatible it is not possible to change this. - - Macro: int _POSIX_SAVED_IDS - If this symbol is defined, it indicates that the system remembers - the effective user and group IDs of a process before it executes an - executable file with the set-user-ID or set-group-ID bits set, and - that explicitly changing the effective user or group IDs back to - these values is permitted. If this option is not defined, then if - a nonprivileged process changes its effective user or group ID to - the real user or group ID of the process, it can't change it back - again. *Note Enable/Disable Setuid::. + Some other functions also use the netgroups state. Currently these +are the `innetgr' function and parts of the implementation of the +`compat' service part of the NSS implementation. - For the following macros, if the macro is defined in `unistd.h', -then its value indicates whether the option is supported. A value of -`-1' means no, and any other value means yes.

This means the returned values are valid even after other + netgroup related functions are called. - - Macro: int _POSIX2_FORT_RUN - If this symbol is defined, it indicates that the system has the - POSIX.2 `asa' command to interpret Fortran carriage control. The - GNU C library never defines this, because we don't know what the - system has. + The return value is `1' if the next entry was successfully read and + the buffer contains enough room to place the strings in it. `0' is + returned in case no more entries are found, the buffer is too + small, or internal errors occurred. - - Macro: int _POSIX2_LOCALEDEF - If this symbol is defined, it indicates that the system has the - POSIX.2 `localedef' command.

First, let's review the various ways computer +systems are named, which is a little complicated because of the history +of the development of the Internet. -`_SC_MEMLOCK_RANGE' - Inquire about the parameter corresponding to - `_POSIX_MEMLOCK_RANGE'. + Every Unix system (also known as a host) has a host name, whether +it's connected to a network or not. In its simplest form, as used +before computer networks were an issue, it's just a word like `chicken'. -`_SC_MEMORY_PROTECTION' - Inquire about the parameter corresponding to - `_POSIX_MEMORY_PROTECTION'. + But any system attached to the Internet or any network like it +conforms to a more rigorous naming convention as part of the Domain +Name System (DNS). In DNS, every host name is composed of two parts: -`_SC_MESSAGE_PASSING' - Inquire about the parameter corresponding to - `_POSIX_MESSAGE_PASSING'. + 1. hostname -`_SC_SEMAPHORES' - Inquire about the parameter corresponding to `_POSIX_SEMAPHORES'. + 2. domain name -`_SC_SHARED_MEMORY_OBJECTS' - Inquire about the parameter corresponding to - `_POSIX_SHARED_MEMORY_OBJECTS'. + You will note that "hostname" looks a lot like "host name", but is +not the same thing, and that people often incorrectly refer to entire +host names as "domain names." -`_SC_AIO_LISTIO_MAX' - Inquire about the parameter corresponding to - `_POSIX_AIO_LISTIO_MAX'. + In DNS, the full host name is properly called the FQDN (Fully +Qualified Domain Name) and consists of the hostname, then a period, +then the domain name. The domain name itself usually has multiple +components separated by periods. So for example, a system's hostname +may be `chicken' and its domain name might be `ai.mit.edu', so its FQDN +(which is its host name) is `chicken.ai.mit.edu'. -`_SC_AIO_MAX' - Inquire about the parameter corresponding to `_POSIX_AIO_MAX'. + Adding to the confusion, though, is that DNS is not the only name +space in which a computer needs to be known. Another name space is the +NIS (aka YP) name space. For NIS purposes, there is another domain +name, which is called the NIS domain name or the YP domain name. It +need not have anything to do with the DNS domain name. -`_SC_AIO_PRIO_DELTA_MAX' - Inquire the value by which a process can decrease its asynchronous - I/O priority level from its own scheduling priority. This - corresponds to the run-time invariant value `AIO_PRIO_DELTA_MAX'. + Confusing things even more is the fact that in DNS, it is possible +for multiple FQDNs to refer to the same system. However, there is +always exactly one of them that is the true host name, and it is called +the canonical FQDN. -`_SC_DELAYTIMER_MAX' - Inquire about the parameter corresponding to - `_POSIX_DELAYTIMER_MAX'. + In some contexts, the host name is called a "node name." -`_SC_MQ_OPEN_MAX' - Inquire about the parameter corresponding to `_POSIX_MQ_OPEN_MAX'. + For more information on DNS host naming, *Note Host Names::. -`_SC_MQ_PRIO_MAX' - Inquire about the parameter corresponding to `_POSIX_MQ_PRIO_MAX'. + Prototypes for these functions appear in `unistd.h'. -`_SC_RTSIG_MAX' - Inquire about the parameter corresponding to `_POSIX_RTSIG_MAX'. + The programs `hostname', `hostid', and `domainname' work by calling +these functions. -`_SC_SEM_NSEMS_MAX' - Inquire about the parameter corresponding to - `_POSIX_SEM_NSEMS_MAX'. + - Function: int gethostname (char *NAME, size_t SIZE) + This function returns the host name of the system on which it is + called, in the array NAME. The SIZE argument specifies the size of + this array, in bytes.

This function and the +associated data type are declared in the header file `sys/utsname.h'. -`_SC_THREAD_ATTR_STACKSIZE' - Inquire about the parameter corresponding to - `_POSIX_THREAD_ATTR_STACKSIZE'. + As a bonus, `uname' also gives some information identifying the +particular system your program is running on. This is the same +information which you can get with functions targetted to this purpose +described in *Note Host Identification::. -`_SC_THREAD_PRIORITY_SCHEDULING' - Inquire about the parameter corresponding to - `_POSIX_THREAD_PRIORITY_SCHEDULING'. + - Data Type: struct utsname + The `utsname' structure is used to hold information returned by + the `uname' function. It has the following members: -`_SC_THREAD_PRIO_INHERIT' - Inquire about the parameter corresponding to - `_POSIX_THREAD_PRIO_INHERIT'. + `char sysname[]' + This is the name of the operating system in use. -`_SC_THREAD_PRIO_PROTECT' - Inquire about the parameter corresponding to - `_POSIX_THREAD_PRIO_PROTECT'. + `char release[]' + This is the current release level of the operating system + implementation. -`_SC_THREAD_PROCESS_SHARED' - Inquire about the parameter corresponding to - `_POSIX_THREAD_PROCESS_SHARED'. + `char version[]' + This is the current version level within the release of the + operating system. -`_SC_2_C_DEV' - Inquire about whether the system has the POSIX.2 C compiler - command, `c89'. + `char machine[]' + This is a description of the type of hardware that is in use. -`_SC_2_FORT_DEV' - Inquire about whether the system has the POSIX.2 Fortran compiler - command, `fort77'. + Some systems provide a mechanism to interrogate the kernel + directly for this information. On systems without such a + mechanism, the GNU C library fills in this field based on the + configuration name that was specified when building and + installing the library. -`_SC_2_FORT_RUN' - Inquire about whether the system has the POSIX.2 `asa' command to - interpret Fortran carriage control. + GNU uses a three-part name to describe a system + configuration; the three parts are CPU, MANUFACTURER and + SYSTEM-TYPE, and they are separated with dashes. Any + possible combination of three names is potentially + meaningful, but most such combinations are meaningless in + practice and even the meaningful ones are not necessarily + supported by any particular GNU program. -`_SC_2_LOCALEDEF' - Inquire about whether the system has the POSIX.2 `localedef' - command. + Since the value in `machine' is supposed to describe just the + hardware, it consists of the first two parts of the + configuration name: `CPU-MANUFACTURER'. For example, it + might be one of these: -`_SC_2_SW_DEV' - Inquire about whether the system has the POSIX.2 commands `ar', - `make', and `strip'. + `"sparc-sun"', `"i386-ANYTHING"', `"m68k-hp"', + `"m68k-sony"', `"m68k-sun"', `"mips-dec"' -`_SC_BC_BASE_MAX' - Inquire about the maximum value of `obase' in the `bc' utility. + `char nodename[]' + This is the host name of this particular computer. In the + GNU C library, the value is the same as that returned by + `gethostname'; see *Note Host Identification::. -`_SC_BC_DIM_MAX' - Inquire about the maximum size of an array in the `bc' utility. + gethostname() is implemented with a call to uname(). -`_SC_BC_SCALE_MAX' - Inquire about the maximum value of `scale' in the `bc' utility. + `char domainname[]' + This is the NIS or YP domain name. It is the same value + returned by `getdomainname'; see *Note Host Identification::. + This element is a relatively recent invention and use of it + is not as portable as use of the rest of the structure. -`_SC_BC_STRING_MAX' - Inquire about the maximum size of a string constant in the `bc' - utility. -`_SC_COLL_WEIGHTS_MAX' - Inquire about the maximum number of weights that can necessarily - be used in defining the collating sequence for a locale. + - Function: int uname (struct utsname *INFO) + The `uname' function fills in the structure pointed to by INFO + with information about the operating system and host machine. A + non-negative value indicates that the data was successfully stored. -`_SC_EXPR_NEST_MAX' - Inquire about the maximum number of expressions nested within - parentheses when using the `expr' utility. + `-1' as the value indicates an error. The only error possible is + `EFAULT', which we normally don't mention as it is always a + possibility. -`_SC_LINE_MAX' - Inquire about the maximum size of a text line that the POSIX.2 text - utilities can handle. + +File: libc.info, Node: Filesystem Handling, Next: System Parameters, Prev: Platform Type, Up: System Management -`_SC_EQUIV_CLASS_MAX' - Inquire about the maximum number of weights that can be assigned - to an entry of the `LC_COLLATE' category `order' keyword in a - locale definition. The GNU C library does not presently support - locale definitions. +Controlling and Querying Mounts +=============================== -`_SC_VERSION' - Inquire about the version number of POSIX.1 that the library and - kernel support. + All files are in filesystems, and before you can access any file, its +filesystem must be mounted. Because of Unix's concept of _Everything +is a file_, mounting of filesystems is central to doing almost +anything. This section explains how to find out what filesystems are +currently mounted and what filesystems are available for mounting, and +how to change what is mounted. -`_SC_2_VERSION' - Inquire about the version number of POSIX.2 that the system - utilities support. + The classic filesystem is the contents of a disk drive. The concept +is considerably more abstract, though, and lots of things other than +disk drives can be mounted. -`_SC_PAGESIZE' - Inquire about the virtual memory page size of the machine. - `getpagesize' returns the same value (*note Query Memory - Parameters::). + Some block devices don't correspond to traditional devices like disk +drives. For example, a loop device is a block device whose driver uses +a regular file in another filesystem as its medium. So if that regular +file contains appropriate data for a filesystem, you can by mounting the +loop device essentially mount a regular file. -`_SC_NPROCESSORS_CONF' - Inquire about the number of configured processors. + Some filesystems aren't based on a device of any kind. The "proc" +filesystem, for example, contains files whose data is made up by the +filesystem driver on the fly whenever you ask for it. And when you +write to it, the data you write causes changes in the system. No data +gets stored. -`_SC_NPROCESSORS_ONLN' - Inquire about the number of processors online. +* Menu: -`_SC_PHYS_PAGES' - Inquire about the number of physical pages in the system. +* Mount Information:: What is or could be mounted? +* Mount-Unmount-Remount:: Controlling what is mounted and how -`_SC_AVPHYS_PAGES' - Inquire about the number of available physical pages in the system. + +File: libc.info, Node: Mount Information, Next: Mount-Unmount-Remount, Up: Filesystem Handling -`_SC_ATEXIT_MAX' - Inquire about the number of functions which can be registered as - termination functions for `atexit'; *note Cleanups on Exit::. +Mount Information +----------------- -`_SC_XOPEN_VERSION' - Inquire about the parameter corresponding to `_XOPEN_VERSION'. + For some programs it is desirable and necessary to access information +about whether a certain filesystem is mounted and, if it is, where, or +simply to get lists of all the available filesystems. The GNU libc +provides some functions to retrieve this information portably. -`_SC_XOPEN_XCU_VERSION' - Inquire about the parameter corresponding to `_XOPEN_XCU_VERSION'. + Traditionally Unix systems have a file named `/etc/fstab' which +describes all possibly mounted filesystems. The `mount' program uses +this file to mount at startup time of the system all the necessary +filesystems. The information about all the filesystems actually mounted +is normally kept in a file named `/etc/mtab'. Both files share the +same syntax and it is crucial that this syntax is followed all the +time. Therefore it is best to never directly write the files. The +functions described in this section can do this and they also provide +the functionality to convert the external textual representation to the +internal representation. -`_SC_XOPEN_UNIX' - Inquire about the parameter corresponding to `_XOPEN_UNIX'. + Note that the `fstab' and `mtab' files are maintained on a system by +_convention_. It is possible for the files not to exist or not to be +consistent with what is really mounted or available to mount, if the +system's administration policy allows it. But programs that mount and +unmount filesystems typically maintain and use these files as described +herein. -`_SC_XOPEN_REALTIME' - Inquire about the parameter corresponding to `_XOPEN_REALTIME'. + The filenames given above should never be used directly. The +portable way to handle these file is to use the macros `_PATH_FSTAB', +defined in `fstab.h' and `_PATH_MNTTAB', defined in `mntent.h', +respectively. There are also two alternate macro names `FSTAB' and +`_PATH_MOUNTED' defined but both names are deprecated and kept only for +backward compatibility. The two former names should always be used. -`_SC_XOPEN_REALTIME_THREADS' - Inquire about the parameter corresponding to - `_XOPEN_REALTIME_THREADS'. +* Menu: -`_SC_XOPEN_LEGACY' - Inquire about the parameter corresponding to `_XOPEN_LEGACY'. +* fstab:: The `fstab' file +* mtab:: The `mtab' file +* Other Mount Information:: Other (non-libc) sources of mount information -`_SC_XOPEN_CRYPT' - Inquire about the parameter corresponding to `_XOPEN_CRYPT'. + +File: libc.info, Node: fstab, Next: mtab, Up: Mount Information -`_SC_XOPEN_ENH_I18N' - Inquire about the parameter corresponding to `_XOPEN_ENH_I18N'. +The `fstab' file +................ -`_SC_XOPEN_SHM' - Inquire about the parameter corresponding to `_XOPEN_SHM'. + The internal representation for entries of the file is +`struct fstab', defined in `fstab.h'. -`_SC_XOPEN_XPG2' - Inquire about the parameter corresponding to `_XOPEN_XPG2'. + - Data Type: struct fstab + This structure is used with the `getfsent', `getfsspec', and + `getfsfile' functions. -`_SC_XOPEN_XPG3' - Inquire about the parameter corresponding to `_XOPEN_XPG3'. + `char *fs_spec' + This element describes the device from which the filesystem + is mounted. Normally this is the name of a special device, + such as a hard disk partition, but it could also be a more or + less generic string. For "NFS" it would be a hostname and + directory name combination. -`_SC_XOPEN_XPG4' - Inquire about the parameter corresponding to `_XOPEN_XPG4'. + Even though the element is not declared `const' it shouldn't + be modified. The missing `const' has historic reasons, since + this function predates ISO C. The same is true for the other + string elements of this structure. -`_SC_CHAR_BIT' - Inquire about the number of bits in a variable of type `char'. + `char *fs_file' + This describes the mount point on the local system. I.e., + accessing any file in this filesystem has implicitly or + explicitly this string as a prefix. -`_SC_CHAR_MAX' - Inquire about the maximum value which can be stored in a variable - of type `char'. + `char *fs_vfstype' + This is the type of the filesystem. Depending on what the + underlying kernel understands it can be any string. -`_SC_CHAR_MIN' - Inquire about the minimum value which can be stored in a variable - of type `char'. + `char *fs_mntops' + This is a string containing options passed to the kernel with + the `mount' call. Again, this can be almost anything. There + can be more than one option, separated from the others by a + comma. Each option consists of a name and an optional value + part, introduced by an `=' character. -`_SC_INT_MAX' - Inquire about the maximum value which can be stored in a variable - of type `int'. + If the value of this element must be processed it should + ideally be done using the `getsubopt' function; see *Note + Suboptions::. -`_SC_INT_MIN' - Inquire about the minimum value which can be stored in a variable - of type `int'. + `const char *fs_type' + This name is poorly chosen. This element points to a string + (possibly in the `fs_mntops' string) which describes the + modes with which the filesystem is mounted. `fstab' defines + five macros to describe the possible values: -`_SC_LONG_BIT' - Inquire about the number of bits in a variable of type `long int'. + `FSTAB_RW' + The filesystems gets mounted with read and write enabled. -`_SC_WORD_BIT' - Inquire about the number of bits in a variable of a register word. + `FSTAB_RQ' + The filesystems gets mounted with read and write + enabled. Write access is restricted by quotas. -`_SC_MB_LEN_MAX' - Inquire the maximum length of a multi-byte representation of a wide - character value. + `FSTAB_RO' + The filesystem gets mounted read-only. -`_SC_NZERO' - Inquire about the value used to internally represent the zero - priority level for the process execution. + `FSTAB_SW' + This is not a real filesystem, it is a swap device. -`SC_SSIZE_MAX' - Inquire about the maximum value which can be stored in a variable - of type `ssize_t'. + `FSTAB_XX' + This entry from the `fstab' file is totally ignored. -`_SC_SCHAR_MAX' - Inquire about the maximum value which can be stored in a variable - of type `signed char'. + Testing for equality with these value must happen using + `strcmp' since these are all strings. Comparing the pointer + will probably always fail. -`_SC_SCHAR_MIN' - Inquire about the minimum value which can be stored in a variable - of type `signed char'. + `int fs_freq' + This element describes the dump frequency in days. -`_SC_SHRT_MAX' - Inquire about the maximum value which can be stored in a variable - of type `short int'. + `int fs_passno' + This element describes the pass number on parallel dumps. It + is closely related to the `dump' utility used on Unix systems. -`_SC_SHRT_MIN' - Inquire about the minimum value which can be stored in a variable - of type `short int'. + To read the entire content of the of the `fstab' file the GNU libc +contains a set of three functions which are designed in the usual way. -`_SC_UCHAR_MAX' - Inquire about the maximum value which can be stored in a variable - of type `unsigned char'. + - Function: int setfsent (void) + This function makes sure that the internal read pointer for the + `fstab' file is at the beginning of the file. This is done by + either opening the file or resetting the read pointer. -`_SC_UINT_MAX' - Inquire about the maximum value which can be stored in a variable - of type `unsigned int'. + Since the file handle is internal to the libc this function is not + thread-safe. -`_SC_ULONG_MAX' - Inquire about the maximum value which can be stored in a variable - of type `unsigned long int'. + This function returns a non-zero value if the operation was + successful and the `getfs*' functions can be used to read the + entries of the file. -`_SC_USHRT_MAX' - Inquire about the maximum value which can be stored in a variable - of type `unsigned short int'. + - Function: void endfsent (void) + This function makes sure that all resources acquired by a prior + call to `setfsent' (explicitly or implicitly by calling + `getfsent') are freed. -`_SC_NL_ARGMAX' - Inquire about the parameter corresponding to `NL_ARGMAX'. + - Function: struct fstab * getfsent (void) + This function returns the next entry of the `fstab' file. If this + is the first call to any of the functions handling `fstab' since + program start or the last call of `endfsent', the file will be + opened. -`_SC_NL_LANGMAX' - Inquire about the parameter corresponding to `NL_LANGMAX'. + The function returns a pointer to a variable of type `struct + fstab'. This variable is shared by all threads and therefore this + function is not thread-safe. If an error occurred `getfsent' + returns a `NULL' pointer. -`_SC_NL_MSGMAX' - Inquire about the parameter corresponding to `NL_MSGMAX'. + - Function: struct fstab * getfsspec (const char *NAME) + This function returns the next entry of the `fstab' file which has + a string equal to NAME pointed to by the `fs_spec' element. Since + there is normally exactly one entry for each special device it + makes no sense to call this function more than once for the same + argument. If this is the first call to any of the functions + handling `fstab' since program start or the last call of + `endfsent', the file will be opened. -`_SC_NL_NMAX' - Inquire about the parameter corresponding to `NL_NMAX'. + The function returns a pointer to a variable of type `struct + fstab'. This variable is shared by all threads and therefore this + function is not thread-safe. If an error occurred `getfsent' + returns a `NULL' pointer. -`_SC_NL_SETMAX' - Inquire about the parameter corresponding to `NL_SETMAX'. + - Function: struct fstab * getfsfile (const char *NAME) + This function returns the next entry of the `fstab' file which has + a string equal to NAME pointed to by the `fs_file' element. Since + there is normally exactly one entry for each mount point it makes + no sense to call this function more than once for the same + argument. If this is the first call to any of the functions + handling `fstab' since program start or the last call of + `endfsent', the file will be opened. -`_SC_NL_TEXTMAX' - Inquire about the parameter corresponding to `NL_TEXTMAX'. + The function returns a pointer to a variable of type `struct + fstab'. This variable is shared by all threads and therefore this + function is not thread-safe.

There might be many more options which are + possible so it doesn't make much sense to rely on these + macros but to be consistent here is the list: -`_POSIX_CHILD_MAX' - The value of this macro is the most restrictive limit permitted by - POSIX for the maximum number of simultaneous processes per real - user ID. Its value is `6'. + `MNTOPT_DEFAULTS' + Expands to `"defaults"'. This option should be used + alone since it indicates all values for the customizable + values are chosen to be the default. -`_POSIX_NGROUPS_MAX' - The value of this macro is the most restrictive limit permitted by - POSIX for the maximum number of supplementary group IDs per - process. Its value is `0'. + `MNTOPT_RO' + Expands to `"ro"'. See the `FSTAB_RO' value, it means + the filesystem is mounted read-only. -`_POSIX_OPEN_MAX' - The value of this macro is the most restrictive limit permitted by - POSIX for the maximum number of files that a single process can - have open simultaneously. Its value is `16'. + `MNTOPT_RW' + Expand to `"rw"'. See the `FSTAB_RW' value, it means the + filesystem is mounted with read and write permissions. -`_POSIX_SSIZE_MAX' - The value of this macro is the most restrictive limit permitted by - POSIX for the maximum value that can be stored in an object of type - `ssize_t'. Its value is `32767'. + `MNTOPT_SUID' + Expands to `"suid"'. This means that the SUID bit + (*note How Change Persona::) is respected when a program + from the filesystem is started. -`_POSIX_STREAM_MAX' - The value of this macro is the most restrictive limit permitted by - POSIX for the maximum number of streams that a single process can - have open simultaneously. Its value is `8'. + `MNTOPT_NOSUID' + Expands to `"nosuid"'. This is the opposite of + `MNTOPT_SUID', the SUID bit for all files from the + filesystem is ignored. -`_POSIX_TZNAME_MAX' - The value of this macro is the most restrictive limit permitted by - POSIX for the maximum length of a time zone name. Its value is - `3'. + `MNTOPT_NOAUTO' + Expands to `"noauto"'. At startup time the `mount' + program will ignore this entry if it is started with the + `-a' option to mount all filesystems mentioned in the + `fstab' file. -`_POSIX2_RE_DUP_MAX' - The value of this macro is the most restrictive limit permitted by - POSIX for the numbers used in the `\{MIN,MAX\}' construct in a - regular expression. Its value is `255'. + As for the `FSTAB_*' entries introduced above it is important + to use `strcmp' to check for equality. - -File: libc.info, Node: Limits for Files, Next: Options for Files, Prev: Minimums, Up: System Configuration + `mnt_freq' + This elements corresponds to `fs_freq' and also specifies the + frequency in days in which dumps are made. -Limits on File System Capacity -============================== + `mnt_passno' + This element is equivalent to `fs_passno' with the same + meaning which is uninteresting for all programs beside `dump'. - The POSIX.1 standard specifies a number of parameters that describe -the limitations of the file system. It's possible for the system to -have a fixed, uniform limit for a parameter, but this isn't the usual -case. On most systems, it's possible for different file systems (and, -for some parameters, even different files) to have different maximum -limits. For example, this is very likely if you use NFS to mount some -of the file systems from other machines. + For accessing the `mtab' file there is again a set of three +functions to access all entries in a row. Unlike the functions to +handle `fstab' these functions do not access a fixed file and there is +even a thread safe variant of the get function. Beside this the GNU +libc contains functions to alter the file and test for specific options. - Each of the following macros is defined in `limits.h' only if the -system has a fixed, uniform limit for the parameter in question. If the -system allows different file systems or files to have different limits, -then the macro is undefined; use `pathconf' or `fpathconf' to find out -the limit that applies to a particular file. *Note Pathconf::. + - Function: FILE * setmntent (const char *FILE, const char *MODE) + The `setmntent' function prepares the file named FILE which must + be in the format of a `fstab' and `mtab' file for the upcoming + processing through the other functions of the family. The MODE + parameter can be chosen in the way the OPENTYPE parameter for + `fopen' (*note Opening Streams::) can be chosen. If the file is + opened for writing the file is also allowed to be empty. - Each parameter also has another macro, with a name starting with -`_POSIX', which gives the lowest value that the limit is allowed to -have on _any_ POSIX system. *Note File Minimums::. + If the file was successfully opened `setmntent' returns a file + descriptor for future use. Otherwise the return value is `NULL' + and `errno' is set accordingly. - - Macro: int LINK_MAX - The uniform system limit (if any) for the number of names for a - given file. *Note Hard Links::. + - Function: int endmntent (FILE *STREAM) + This function takes for the STREAM parameter a file handle which + previously was returned from the `setmntent' call. `endmntent' + closes the stream and frees all resources. - - Macro: int MAX_CANON - The uniform system limit (if any) for the amount of text in a line - of input when input editing is enabled. *Note Canonical or Not::. + The return value is 1 unless an error occurred in which case it is + 0. - - Macro: int MAX_INPUT - The uniform system limit (if any) for the total number of - characters typed ahead as input. *Note I/O Queues::. + - Function: struct mntent * getmntent (FILE *STREAM) + The `getmntent' function takes as the parameter a file handle + previously returned by successful call to `setmntent'. It returns + a pointer to a static variable of type `struct mntent' which is + filled with the information from the next entry from the file + currently read. - - Macro: int NAME_MAX - The uniform system limit (if any) for the length of a file name - component. + The file format used prescribes the use of spaces or tab + characters to separate the fields. This makes it harder to use + name containing one of these characters (e.g., mount points using + spaces). Therefore these characters are encoded in the files and + the `getmntent' function takes care of the decoding while reading + the entries back in. `'\040'' is used to encode a space + character, `'\012'' to encode a tab character and `'\\'' to encode + a backslash. - - Macro: int PATH_MAX - The uniform system limit (if any) for the length of an entire file - name (that is, the argument given to system calls such as `open'). + If there was an error or the end of the file is reached the return + value is `NULL'. - - Macro: int PIPE_BUF - The uniform system limit (if any) for the number of bytes that can - be written atomically to a pipe. If multiple processes are - writing to the same pipe simultaneously, output from different - processes might be interleaved in chunks of this size. *Note - Pipes and FIFOs::. + This function is not thread-safe since all calls to this function + return a pointer to the same static variable. `getmntent_r' + should be used in situations where multiple threads access the + file. - These are alternative macro names for some of the same information. + - Function: struct mntent * getmntent_r (FILE *STREAM, struct mentent + *RESULT, char *BUFFER, int BUFSIZE) + The `getmntent_r' function is the reentrant variant of + `getmntent'. It also returns the next entry from the file and + returns a pointer. The actual variable the values are stored in + is not static, though. Instead the function stores the values in + the variable pointed to by the RESULT parameter. Additional + information (e.g., the strings pointed to by the elements of the + result) are kept in the buffer of size BUFSIZE pointed to by + BUFFER. - - Macro: int MAXNAMLEN - This is the BSD name for `NAME_MAX'. It is defined in `dirent.h'. + Escaped characters (space, tab, backslash) are converted back in + the same way as it happens for `getmentent'. - - Macro: int FILENAME_MAX - The value of this macro is an integer constant expression that - represents the maximum length of a file name string. It is - defined in `stdio.h'. + The function returns a `NULL' pointer in error cases. Errors + could be: + * error while reading the file, - Unlike `PATH_MAX', this macro is defined even if there is no actual - limit imposed. In such a case, its value is typically a very large - number. *This is always the case on the GNU system.* + * end of file reached, - *Usage Note:* Don't use `FILENAME_MAX' as the size of an array in - which to store a file name! You can't possibly make an array that - big! Use dynamic allocation (*note Memory Allocation::) instead. + * BUFSIZE is too small for reading a complete new entry. - -File: libc.info, Node: Options for Files, Next: File Minimums, Prev: Limits for Files, Up: System Configuration + - Function: int addmntent (FILE *STREAM, const struct mntent *MNT) + The `addmntent' function allows adding a new entry to the file + previously opened with `setmntent'. The new entries are always + appended. I.e., even if the position of the file descriptor is + not at the end of the file this function does not overwrite an + existing entry following the current position. -Optional Features in File Support -================================= + The implication of this is that to remove an entry from a file one + has to create a new file while leaving out the entry to be removed + and after closing the file remove the old one and rename the new + file to the chosen name. - POSIX defines certain system-specific options in the system calls for -operating on files. Some systems support these options and others do -not. Since these options are provided in the kernel, not in the -library, simply using the GNU C library does not guarantee that any of -these features is supported; it depends on the system you are using. -They can also vary between file systems on a single machine. + This function takes care of spaces and tab characters in the names + to be written to the file. It converts them and the backslash + character into the format describe in the `getmntent' description + above. - This section describes the macros you can test to determine whether a -particular option is supported on your machine. If a given macro is -defined in `unistd.h', then its value says whether the corresponding -feature is supported. (A value of `-1' indicates no; any other value -indicates yes.) If the macro is undefined, it means particular files -may or may not support the feature. + This function returns 0 in case the operation was successful. + Otherwise the return value is 1 and `errno' is set appropriately. - Since all the machines that support the GNU C library also support -NFS, one can never make a general statement about whether all file -systems support the `_POSIX_CHOWN_RESTRICTED' and `_POSIX_NO_TRUNC' -features. So these names are never defined as macros in the GNU C -library. + - Function: char * hasmntopt (const struct mntent *MNT, const char + *OPT) + This function can be used to check whether the string pointed to + by the `mnt_opts' element of the variable pointed to by MNT + contains the option OPT. If this is true a pointer to the + beginning of the option in the `mnt_opts' element is returned. If + no such option exists the function returns `NULL'. - - Macro: int _POSIX_CHOWN_RESTRICTED - If this option is in effect, the `chown' function is restricted so - that the only changes permitted to nonprivileged processes is to - change the group owner of a file to either be the effective group - ID of the process, or one of its supplementary group IDs. *Note - File Owner::. + This function is useful to test whether a specific option is + present but when all options have to be processed one is better + off with using the `getsubopt' function to iterate over all + options in the string. - - Macro: int _POSIX_NO_TRUNC - If this option is in effect, file name components longer than - `NAME_MAX' generate an `ENAMETOOLONG' error. Otherwise, file name - components that are too long are silently truncated. + +File: libc.info, Node: Other Mount Information, Prev: mtab, Up: Mount Information - - Macro: unsigned char _POSIX_VDISABLE - This option is only meaningful for files that are terminal devices. - If it is enabled, then handling for special control characters can - be disabled individually. *Note Special Characters::. +Other (Non-libc) Sources of Mount Information +............................................. - If one of these macros is undefined, that means that the option -might be in effect for some files and not for others. To inquire about -a particular file, call `pathconf' or `fpathconf'. *Note Pathconf::. + On a system with a Linux kernel and the `proc' filesystem, you can +get information on currently mounted filesystems from the file `mounts' +in the `proc' filesystem. Its format is similar to that of the `mtab' +file, but represents what is truly mounted without relying on +facilities outside the kernel to keep `mtab' up to date.  -File: libc.info, Node: File Minimums, Next: Pathconf, Prev: Options for Files, Up: System Configuration +File: libc.info, Node: Mount-Unmount-Remount, Prev: Mount Information, Up: Filesystem Handling -Minimum Values for File System Limits -===================================== +Mount, Unmount, Remount +----------------------- - Here are the names for the POSIX minimum upper bounds for some of the -above parameters. The significance of these values is that you can -safely push to these limits without checking whether the particular -system you are using can go that far. In most cases GNU systems do not -have these strict limitations. The actual limit should be requested if -necessary. + This section describes the functions for mounting, unmounting, and +remounting filesystems. -`_POSIX_LINK_MAX' - The most restrictive limit permitted by POSIX for the maximum - value of a file's link count. The value of this constant is `8'; - thus, you can always make up to eight names for a file without - running into a system limit. + Only the superuser can mount, unmount, or remount a filesystem. -`_POSIX_MAX_CANON' - The most restrictive limit permitted by POSIX for the maximum - number of bytes in a canonical input line from a terminal device. - The value of this constant is `255'. + These functions do not access the `fstab' and `mtab' files. You +should maintain and use these separately. *Note Mount Information::. -`_POSIX_MAX_INPUT' - The most restrictive limit permitted by POSIX for the maximum - number of bytes in a terminal device input queue (or typeahead - buffer). *Note Input Modes::. The value of this constant is - `255'. + The symbols in this section are declared in `sys/mount.h'. -`_POSIX_NAME_MAX' - The most restrictive limit permitted by POSIX for the maximum - number of bytes in a file name component. The value of this - constant is `14'. + - Function: int mount (const char *SPECIAL_FILE, const char *DIR, + const char *FSTYPE, unsigned long int OPTIONS, const void + *DATA) + `mount' mounts or remounts a filesystem. The two operations are + quite different and are merged rather unnaturally into this one + function. The `MS_REMOUNT' option, explained below, determines + whether `mount' mounts or remounts. -`_POSIX_PATH_MAX' - The most restrictive limit permitted by POSIX for the maximum - number of bytes in a file name. The value of this constant is - `256'. + For a mount, the filesystem on the block device represented by the + device special file named SPECIAL_FILE gets mounted over the mount + point DIR. This means that the directory DIR (along with any + files in it) is no longer visible; in its place (and still with + the name DIR) is the root directory of the filesystem on the + device. -`_POSIX_PIPE_BUF' - The most restrictive limit permitted by POSIX for the maximum - number of bytes that can be written atomically to a pipe. The - value of this constant is `512'. + As an exception, if the filesystem type (see below) is one which + is not based on a device (e.g. "proc"), `mount' instantiates a + filesystem and mounts it over DIR and ignores SPECIAL_FILE. -`SYMLINK_MAX' - Maximum number of bytes in a symbolic link. + For a remount, DIR specifies the mount point where the filesystem + to be remounted is (and remains) mounted and SPECIAL_FILE is + ignored. Remounting a filesystem means changing the options that + control operations on the filesystem while it is mounted. It does + not mean unmounting and mounting again. -`POSIX_REC_INCR_XFER_SIZE' - Recommended increment for file transfer sizes between the - `POSIX_REC_MIN_XFER_SIZE' and `POSIX_REC_MAX_XFER_SIZE' values. + For a mount, you must identify the type of the filesystem as + FSTYPE. This type tells the kernel how to access the filesystem + and can be thought of as the name of a filesystem driver. The + acceptable values are system dependent. On a system with a Linux + kernel and the `proc' filesystem, the list of possible values is + in the file `filesystems' in the `proc' filesystem (e.g. type `cat + /proc/filesystems' to see the list). With a Linux kernel, the + types of filesystems that `mount' can mount, and their type names, + depends on what filesystem drivers are configured into the kernel + or loaded as loadable kernel modules. An example of a common + value for FSTYPE is `ext2'. -`POSIX_REC_MAX_XFER_SIZE' - Maximum recommended file transfer size. + For a remount, `mount' ignores FSTYPE. -`POSIX_REC_MIN_XFER_SIZE' - Minimum recommended file transfer size. + OPTIONS specifies a variety of options that apply until the + filesystem is unmounted or remounted. The precise meaning of an + option depends on the filesystem and with some filesystems, an + option may have no effect at all. Furthermore, for some + filesystems, some of these options (but never `MS_RDONLY') can be + overridden for individual file accesses via `ioctl'. -`POSIX_REC_XFER_ALIGN' - Recommended file transfer buffer alignment. + OPTIONS is a bit string with bit fields defined using the + following mask and masked value macros: - -File: libc.info, Node: Pathconf, Next: Utility Limits, Prev: File Minimums, Up: System Configuration + `MS_MGC_MASK' + This multibit field contains a magic number. If it does not + have the value `MS_MGC_VAL', `mount' assumes all the + following bits are zero and the DATA argument is a null + string, regardless of their actual values. -Using `pathconf' -================ + `MS_REMOUNT' + This bit on means to remount the filesystem. Off means to + mount it. - When your machine allows different files to have different values -for a file system parameter, you can use the functions in this section -to find out the value that applies to any particular file. + `MS_RDONLY' + This bit on specifies that no writing to the filesystem shall + be allowed while it is mounted. This cannot be overridden by + `ioctl'. This option is available on nearly all filesystems. - These functions and the associated constants for the PARAMETER -argument are declared in the header file `unistd.h'. + `S_IMMUTABLE' + This bit on specifies that no writing to the files in the + filesystem shall be allowed while it is mounted. This can be + overridden for a particular file access by a properly + privileged call to `ioctl'. This option is a relatively new + invention and is not available on many filesystems. - - Function: long int pathconf (const char *FILENAME, int PARAMETER) - This function is used to inquire about the limits that apply to - the file named FILENAME. + `S_APPEND' + This bit on specifies that the only file writing that shall + be allowed while the filesystem is mounted is appending. + Some filesystems allow this to be overridden for a particular + process by a properly privileged call to `ioctl'. This is a + relatively new invention and is not available on many + filesystems. - The PARAMETER argument should be one of the `_PC_' constants - listed below. + `MS_NOSUID' + This bit on specifies that Setuid and Setgid permissions on + files in the filesystem shall be ignored while it is mounted. - The normal return value from `pathconf' is the value you requested. - A value of `-1' is returned both if the implementation does not - impose a limit, and in case of an error. In the former case, - `errno' is not set, while in the latter case, `errno' is set to - indicate the cause of the problem. So the only way to use this - function robustly is to store `0' into `errno' just before calling - it. + `MS_NOEXEC' + This bit on specifies that no files in the filesystem shall + be executed while the filesystem is mounted. - Besides the usual file name errors (*note File Name Errors::), the - following error condition is defined for this function: + `MS_NODEV' + This bit on specifies that no device special files in the + filesystem shall be accessible while the filesystem is + mounted. + + `MS_SYNCHRONOUS' + This bit on specifies that all writes to the filesystem while + it is mounted shall be synchronous; i.e. data shall be synced + before each write completes rather than held in the buffer + cache. + + `MS_MANDLOCK' + This bit on specifies that mandatory locks on files shall be + permitted while the filesystem is mounted. + + `MS_NOATIME' + This bit on specifies that access times of files shall not be + updated when the files are accessed while the filesystem is + mounted. + + `MS_NODIRATIME' + This bit on specifies that access times of directories shall + not be updated when the directories are accessed while the + filesystem in mounted. + + Any bits not covered by the above masks should be set off; + otherwise, results are undefined. + + The meaning of DATA depends on the filesystem type and is + controlled entirely by the filesystem driver in the kernel. + + Example: + + #include + + mount("/dev/hdb", "/cdrom", MS_MGC_VAL | MS_RDONLY | MS_NOSUID, ""); + + mount("/dev/hda2", "/mnt", MS_MGC_VAL | MS_REMOUNT, ""); + + Appropriate arguments for `mount' are conventionally recorded in + the `fstab' table. *Note Mount Information::. + + The return value is zero if the mount or remount is successful. + Otherwise, it is `-1' and `errno' is set appropriately. The + values of `errno' are filesystem dependent, but here is a general + list: + + `EPERM' + The process is not superuser. + + `ENODEV' + The file system type FSTYPE is not known to the kernel. + + `ENOTBLK' + The file DEV is not a block device special file. + + `EBUSY' + * The device is already mounted. + + * The mount point is busy. (E.g. it is some process' + working directory or has a filesystem mounted on it + already). + + * The request is to remount read-only, but there are files + open for write. `EINVAL' - The value of PARAMETER is invalid, or the implementation - doesn't support the PARAMETER for the specific file. + * A remount was attempted, but there is no filesystem + mounted over the specified mount point. - - Function: long int fpathconf (int FILEDES, int PARAMETER) - This is just like `pathconf' except that an open file descriptor - is used to specify the file for which information is requested, - instead of a file name. + * The supposed filesystem has an invalid superblock. - The following `errno' error conditions are defined for this - function: - `EBADF' - The FILEDES argument is not a valid file descriptor. + `EACCES' + * The filesystem is inherently read-only (possibly due to + a switch on the device) and the process attempted to + mount it read/write (by setting the `MS_RDONLY' bit off). + + * SPECIAL_FILE or DIR is not accessible due to file + permissions. + + * SPECIAL_FILE is not accessible because it is in a + filesystem that is mounted with the `MS_NODEV' option. + + + `EM_FILE' + The table of dummy devices is full. `mount' needs to create a + dummy device (aka "unnamed" device) if the filesystem being + mounted is not one that uses a device. + + + - Function: int umount2 (const char *FILE, int FLAGS) + `umount2' unmounts a filesystem. + + You can identify the filesystem to unmount either by the device + special file that contains the filesystem or by the mount point. + The effect is the same. Specify either as the string FILE. + + FLAGS contains the one-bit field identified by the following mask + macro: + + `MNT_FORCE' + This bit on means to force the unmounting even if the + filesystem is busy, by making it unbusy first. If the bit is + off and the filesystem is busy, `umount2' fails with `errno' + = `EBUSY'. Depending on the filesystem, this may override + all, some, or no busy conditions. + + All other bits in FLAGS should be set to zero; otherwise, the + result is undefined. + + Example: + + #include + + umount2("/mnt", MNT_FORCE); + + umount2("/dev/hdd1", 0); + + After the filesystem is unmounted, the directory that was the + mount point is visible, as are any files in it. + + As part of unmounting, `umount2' syncs the filesystem. + + If the unmounting is successful, the return value is zero. + Otherwise, it is `-1' and `errno' is set accordingly: + + `EPERM' + The process is not superuser. + + `EBUSY' + The filesystem cannot be unmounted because it is busy. E.g. + it contains a directory that is some process's working + directory or a file that some process has open. With some + filesystems in some cases, you can avoid this failure with + the `MNT_FORCE' option. `EINVAL' - The value of PARAMETER is invalid, or the implementation - doesn't support the PARAMETER for the specific file. + FILE validly refers to a file, but that file is neither a + mount point nor a device special file of a currently mounted + filesystem. - Here are the symbolic constants that you can use as the PARAMETER -argument to `pathconf' and `fpathconf'. The values are all integer -constants. + This function is not available on all systems. -`_PC_LINK_MAX' - Inquire about the value of `LINK_MAX'. + - Function: int umount (const char *FILE) + `umount' does the same thing as `umount2' with FLAGS set to + zeroes. It is more widely available than `umount2' but since it + lacks the possibility to forcefully unmount a filesystem is + deprecated when `umount2' is also available. -`_PC_MAX_CANON' - Inquire about the value of `MAX_CANON'. + +File: libc.info, Node: System Parameters, Prev: Filesystem Handling, Up: System Management -`_PC_MAX_INPUT' - Inquire about the value of `MAX_INPUT'. +System Parameters +================= -`_PC_NAME_MAX' - Inquire about the value of `NAME_MAX'. + This section describes the `sysctl' function, which gets and sets a +variety of system parameters. -`_PC_PATH_MAX' - Inquire about the value of `PATH_MAX'. + The symbols used in this section are declared in the file `sysctl.h'. -`_PC_PIPE_BUF' - Inquire about the value of `PIPE_BUF'. + - Function: int sysctl (int *NAMES, int NLEN, void *OLDVAL, + size_t *OLDLENP, void *NEWVAL, size_t NEWLEN) -`_PC_CHOWN_RESTRICTED' - Inquire about the value of `_POSIX_CHOWN_RESTRICTED'. + `sysctl' gets or sets a specified system parameter. There are so + many of these parameters that it is not practical to list them all + here, but here are some examples: -`_PC_NO_TRUNC' - Inquire about the value of `_POSIX_NO_TRUNC'. + * network domain name -`_PC_VDISABLE' - Inquire about the value of `_POSIX_VDISABLE'. + * paging parameters -`_PC_SYNC_IO' - Inquire about the value of `_POSIX_SYNC_IO'. + * network Address Resolution Protocol timeout time -`_PC_ASYNC_IO' - Inquire about the value of `_POSIX_ASYNC_IO'. + * maximum number of files that may be open -`_PC_PRIO_IO' - Inquire about the value of `_POSIX_PRIO_IO'. + * root filesystem device -`_PC_SOCK_MAXBUF' - Inquire about the value of `_POSIX_PIPE_BUF'. + * when kernel was built -`_PC_FILESIZEBITS' - Inquire about the availability of large files on the filesystem. + The set of available parameters depends on the kernel + configuration and can change while the system is running, + particularly when you load and unload loadable kernel modules. -`_PC_REC_INCR_XFER_SIZE' - Inquire about the value of `POSIX_REC_INCR_XFER_SIZE'. + The system parameters with which `syslog' is concerned are arranged + in a hierarchical structure like a hierarchical filesystem. To + identify a particular parameter, you specify a path through the + structure in a way analogous to specifying the pathname of a file. + Each component of the path is specified by an integer and each of + these integers has a macro defined for it by `sysctl.h'. NAMES is + the path, in the form of an array of integers. Each component of + the path is one element of the array, in order. NLEN is the + number of components in the path. -`_PC_REC_MAX_XFER_SIZE' - Inquire about the value of `POSIX_REC_MAX_XFER_SIZE'. + For example, the first component of the path for all the paging + parameters is the value `CTL_VM'. For the free page thresholds, + the second component of the path is `VM_FREEPG'. So to get the + free page threshold values, make NAMES an array containing the two + elements `CTL_VM' and `VM_FREEPG' and make NLEN = 2. -`_PC_REC_MIN_XFER_SIZE' - Inquire about the value of `POSIX_REC_MIN_XFER_SIZE'. + The format of the value of a parameter depends on the parameter. + Sometimes it is an integer; sometimes it is an ASCII string; + sometimes it is an elaborate structure. In the case of the free + page thresholds used in the example above, the parameter value is + a structure containing several integers. -`_PC_REC_XFER_ALIGN' - Inquire about the value of `POSIX_REC_XFER_ALIGN'. + In any case, you identify a place to return the parameter's value + with OLDVAL and specify the amount of storage available at that + location as *OLDLENP. *OLDLENP does double duty because it is + also the output location that contains the actual length of the + returned value. + + If you don't want the parameter value returned, specify a null + pointer for OLDVAL. + + To set the parameter, specify the address and length of the new + value as NEWVAL and NEWLEN. If you don't want to set the + parameter, specify a null pointer as NEWVAL. + + If you get and set a parameter in the same `sysctl' call, the value + returned is the value of the parameter before it was set. + + Each system parameter has a set of permissions similar to the + permissions for a file (including the permissions on directories + in its path) that determine whether you may get or set it. For + the purposes of these permissions, every parameter is considered + to be owned by the superuser and Group 0 so processes with that + effective uid or gid may have more access to system parameters. + Unlike with files, the superuser does not invariably have full + permission to all system parameters, because some of them are + designed not to be changed ever. + + `sysctl' returns a zero return value if it succeeds. Otherwise, it + returns `-1' and sets `errno' appropriately.

This makes simple DES insecure for most -purposes, and NIST no longer permits new US government systems to use -simple DES. +`_SC_LOGIN_NAME_MAX' + Inquire about the parameter corresponding to + `_POSIX_LOGIN_NAME_MAX'. - For serious encryption functionality, it is recommended that one of -the many free encryption libraries be used instead of these routines. +`_SC_TTY_NAME_MAX' + Inquire about the parameter corresponding to `_POSIX_TTY_NAME_MAX'. - The DES is a reversible operation which takes a 64-bit block and a -64-bit key, and produces another 64-bit block. Usually the bits are -numbered so that the most-significant bit, the first bit, of each block -is numbered 1. +`_SC_THREAD_DESTRUCTOR_ITERATIONS' + Inquire about the parameter corresponding to + `_POSIX_THREAD_DESTRUCTOR_ITERATIONS'. - Under that numbering, every 8th bit of the key (the 8th, 16th, and so -on) is not used by the encryption algorithm itself. But the key must -have odd parity; that is, out of bits 1 through 8, and 9 through 16, and -so on, there must be an odd number of `1' bits, and this completely -specifies the unused bits. +`_SC_THREAD_KEYS_MAX' + Inquire about the parameter corresponding to + `_POSIX_THREAD_KEYS_MAX'. - - Function: void setkey (const char *KEY) - The `setkey' function sets an internal data structure to be an - expanded form of KEY.

The - result is placed in BLOCK. +`_SC_THREAD_THREADS_MAX' + Inquire about the parameter corresponding to + `_POSIX_THREAD_THREADS_MAX'. - Like `setkey', BLOCK is specified as an array of 64 bits each - stored in a `char', but there are no parity bits in BLOCK. +`_SC_THREAD_ATTR_STACKADDR' + Inquire about the parameter corresponding to + a `_POSIX_THREAD_ATTR_STACKADDR'. - - Function: void setkey_r (const char *KEY, struct crypt_data * DATA) - - Function: void encrypt_r (char *BLOCK, int EDFLAG, struct crypt_data - * DATA) - These are reentrant versions of `setkey' and `encrypt'. The only - difference is the extra parameter, which stores the expanded - version of KEY. Before calling `setkey_r' the first time, - `data->initialized' must be cleared to zero. +`_SC_THREAD_ATTR_STACKSIZE' + Inquire about the parameter corresponding to + `_POSIX_THREAD_ATTR_STACKSIZE'. - The `setkey_r' and `encrypt_r' functions are GNU extensions. -`setkey', `encrypt', `setkey_r', and `encrypt_r' are defined in -`crypt.h'. +`_SC_THREAD_PRIORITY_SCHEDULING' + Inquire about the parameter corresponding to + `_POSIX_THREAD_PRIORITY_SCHEDULING'. - - Function: int ecb_crypt (char *KEY, char *BLOCKS, unsigned LEN, - unsigned MODE) - The function `ecb_crypt' encrypts or decrypts one or more blocks - using DES. Each block is encrypted independently. +`_SC_THREAD_PRIO_INHERIT' + Inquire about the parameter corresponding to + `_POSIX_THREAD_PRIO_INHERIT'. - The BLOCKS and the KEY are stored packed in 8-bit bytes, so that - the first bit of the key is the most-significant bit of `key[0]' - and the 63rd bit of the key is stored as the least-significant bit - of `key[7]'. The KEY should have the correct parity. +`_SC_THREAD_PRIO_PROTECT' + Inquire about the parameter corresponding to + `_POSIX_THREAD_PRIO_PROTECT'. - LEN is the number of bytes in BLOCKS.

The GNU C library does not presently support + locale definitions. - For encryption in CBC mode, each block is exclusive-ored with IVEC - before being encrypted, then IVEC is replaced with the result of - the encryption, then the next block is processed. Decryption is - the reverse of this process. +`_SC_VERSION' + Inquire about the version number of POSIX.1 that the library and + kernel support. - This has the advantage that blocks which are the same before being - encrypted are very unlikely to be the same after being encrypted, - making it much harder to detect patterns in the data. +`_SC_2_VERSION' + Inquire about the version number of POSIX.2 that the system + utilities support. - Usually, IVEC is set to 8 random bytes before encryption starts. - Then the 8 random bytes are transmitted along with the encrypted - data (without themselves being encrypted), and passed back in as - IVEC for decryption. Another possibility is to set IVEC to 8 - zeroes initially, and have the first the block encrypted consist - of 8 random bytes. +`_SC_PAGESIZE' + Inquire about the virtual memory page size of the machine. + `getpagesize' returns the same value (*note Query Memory + Parameters::). - Otherwise, all the parameters are similar to those for `ecb_crypt'. +`_SC_NPROCESSORS_CONF' + Inquire about the number of configured processors. - - Function: void des_setparity (char *KEY) - The function `des_setparity' changes the 64-bit KEY, stored packed - in 8-bit bytes, to have odd parity by altering the low bits of - each byte. +`_SC_NPROCESSORS_ONLN' + Inquire about the number of processors online. - The `ecb_crypt', `cbc_crypt', and `des_setparity' functions and -their accompanying macros are all defined in the header -`rpc/des_crypt.h'. +`_SC_PHYS_PAGES' + Inquire about the number of physical pages in the system. - -File: libc.info, Node: Debugging Support, Next: POSIX Threads, Prev: Cryptographic Functions, Up: Top +`_SC_AVPHYS_PAGES' + Inquire about the number of available physical pages in the system. -Debugging support -***************** +`_SC_ATEXIT_MAX' + Inquire about the number of functions which can be registered as + termination functions for `atexit'; *note Cleanups on Exit::. - Applications are usually debugged using dedicated debugger programs. -But sometimes this is not possible and, in any case, it is useful to -provide the developer with as much information as possible at the time -the problems are experienced.

The usual way to inspect a backtrace of a program -is to use an external debugger such as gdb. However, sometimes it is -useful to obtain a backtrace programatically from within a program, -e.g., for the purposes of logging or diagnostics. +`_SC_XOPEN_LEGACY' + Inquire about the parameter corresponding to `_XOPEN_LEGACY'. - The header file `execinfo.h' declares three functions that obtain -and manipulate backtraces of the current thread. +`_SC_XOPEN_CRYPT' + Inquire about the parameter corresponding to `_XOPEN_CRYPT'. - - Function: int backtrace (void **BUFFER, int SIZE) - The `backtrace' function obtains a backtrace for the current - thread, as a list of pointers, and places the information into - BUFFER. The argument SIZE should be the number of `void *' - elements that will fit into BUFFER. The return value is the - actual number of entries of BUFFER that are obtained, and is at - most SIZE. +`_SC_XOPEN_ENH_I18N' + Inquire about the parameter corresponding to `_XOPEN_ENH_I18N'. - The pointers placed in BUFFER are actually return addresses - obtained by inspecting the stack, one return address per stack - frame. +`_SC_XOPEN_SHM' + Inquire about the parameter corresponding to `_XOPEN_SHM'. - Note that certain compiler optimizations may interfere with - obtaining a valid backtrace. Function inlining causes the inlined - function to not have a stack frame; tail call optimization - replaces one stack frame with another; frame pointer elimination - will stop `backtrace' from interpreting the stack contents - correctly. +`_SC_XOPEN_XPG2' + Inquire about the parameter corresponding to `_XOPEN_XPG2'. - - Function: char ** backtrace_symbols (void *const *BUFFER, int SIZE) - The `backtrace_symbols' function translates the information - obtained from the `backtrace' function into an array of strings. - The argument BUFFER should be a pointer to an array of addresses - obtained via the `backtrace' function, and SIZE is the number of - entries in that array (the return value of `backtrace'). +`_SC_XOPEN_XPG3' + Inquire about the parameter corresponding to `_XOPEN_XPG3'. - The return value is a pointer to an array of strings, which has - SIZE entries just like the array BUFFER. Each string contains a - printable representation of the corresponding element of BUFFER. - It includes the function name (if this can be determined), an - offset into the function, and the actual return address (in - hexadecimal). +`_SC_XOPEN_XPG4' + Inquire about the parameter corresponding to `_XOPEN_XPG4'. - Currently, the function name and offset only be obtained on - systems that use the ELF binary format for programs and libraries. - On other systems, only the hexadecimal return address will be - present. Also, you may need to pass additional flags to the - linker to make the function names available to the program. (For - example, on systems using GNU ld, you must pass (`-rdynamic'.) +`_SC_CHAR_BIT' + Inquire about the number of bits in a variable of type `char'. - The return value of `backtrace_symbols' is a pointer obtained via - the `malloc' function, and it is the responsibility of the caller - to `free' that pointer. Note that only the return value need be - freed, not the individual strings. +`_SC_CHAR_MAX' + Inquire about the maximum value which can be stored in a variable + of type `char'. - The return value is `NULL' if sufficient memory for the strings - cannot be obtained. +`_SC_CHAR_MIN' + Inquire about the minimum value which can be stored in a variable + of type `char'. - - Function: void backtrace_symbols_fd (void *const *BUFFER, int SIZE, - int FD) - The `backtrace_symbols_fd' function performs the same translation - as the function `backtrace_symbols' function. Instead of returning - the strings to the caller, it writes the strings to the file - descriptor FD, one per line. It does not use the `malloc' - function, and can therefore be used in situations where that - function might fail. +`_SC_INT_MAX' + Inquire about the maximum value which can be stored in a variable + of type `int'. - The following program illustrates the use of these functions. Note -that the array to contain the return addresses returned by `backtrace' -is allocated on the stack. Therefore code like this can be used in -situations where the memory handling via `malloc' does not work anymore -(in which case the `backtrace_symbols' has to be replaced by a -`backtrace_symbols_fd' call as well). The number of return addresses -is normally not very large. Even complicated programs rather seldom -have a nesting level of more than, say, 50 and with 200 possible -entries probably all programs should be covered. +`_SC_INT_MIN' + Inquire about the minimum value which can be stored in a variable + of type `int'. - #include - #include - #include - - /* Obtain a backtrace and print it to `stdout'. */ - void - print_trace (void) - { - void *array[10]; - size_t size; - char **strings; - size_t i; - - size = backtrace (array, 10); - strings = backtrace_symbols (array, size); - - printf ("Obtained %zd stack frames.\n", size); - - for (i = 0; i < size; i++) - printf ("%s\n", strings[i]); - - free (strings); - } - - /* A dummy function to make the backtrace more interesting. */ - void - dummy_function (void) - { - print_trace (); - } - - int - main (void) - { - dummy_function (); - return 0; - } +`_SC_LONG_BIT' + Inquire about the number of bits in a variable of type `long int'. - -File: libc.info, Node: POSIX Threads, Next: Language Features, Prev: Debugging Support, Up: Top +`_SC_WORD_BIT' + Inquire about the number of bits in a variable of a register word. -POSIX Threads -************* +`_SC_MB_LEN_MAX' + Inquire the maximum length of a multi-byte representation of a wide + character value. - This chapter describes the pthreads (POSIX threads) library.

Passing `NULL' is equivalent to passing a thread -attribute object with all attributes set to their default values. + The POSIX.1 standard specifies a number of parameters that describe +the limitations of the file system. It's possible for the system to +have a fixed, uniform limit for a parameter, but this isn't the usual +case. On most systems, it's possible for different file systems (and, +for some parameters, even different files) to have different maximum +limits. For example, this is very likely if you use NFS to mount some +of the file systems from other machines. - Attribute objects are consulted only when creating a new thread. The -same attribute object can be used for creating several threads. -Modifying an attribute object after a call to `pthread_create' does not -change the attributes of the thread previously created. + Each of the following macros is defined in `limits.h' only if the +system has a fixed, uniform limit for the parameter in question. If the +system allows different file systems or files to have different limits, +then the macro is undefined; use `pathconf' or `fpathconf' to find out +the limit that applies to a particular file. *Note Pathconf::. - - Function: int pthread_attr_init (pthread_attr_t *ATTR) - `pthread_attr_init' initializes the thread attribute object ATTR - and fills it with default values for the attributes. (The default - values are listed below for each attribute.) + Each parameter also has another macro, with a name starting with +`_POSIX', which gives the lowest value that the limit is allowed to +have on _any_ POSIX system. *Note File Minimums::. - Each attribute ATTRNAME (see below for a list of all attributes) - can be individually set using the function - `pthread_attr_setATTRNAME' and retrieved using the function - `pthread_attr_getATTRNAME'. + - Macro: int LINK_MAX + The uniform system limit (if any) for the number of names for a + given file. *Note Hard Links::. - - Function: int pthread_attr_destroy (pthread_attr_t *ATTR) - `pthread_attr_destroy' destroys the attribute object pointed to by - ATTR releasing any resources associated with it.

The default is 0. + POSIX defines certain system-specific options in the system calls for +operating on files. Some systems support these options and others do +not. Since these options are provided in the kernel, not in the +library, simply using the GNU C library does not guarantee that any of +these features is supported; it depends on the system you are using. +They can also vary between file systems on a single machine. - This attribute is not significant if the scheduling policy is - `SCHED_OTHER'; it only matters for the realtime policies - `SCHED_RR' and `SCHED_FIFO'. + This section describes the macros you can test to determine whether a +particular option is supported on your machine. If a given macro is +defined in `unistd.h', then its value says whether the corresponding +feature is supported. (A value of `-1' indicates no; any other value +indicates yes.) If the macro is undefined, it means particular files +may or may not support the feature. - The scheduling priority of a thread can be changed after creation - with `pthread_setschedparam'. + Since all the machines that support the GNU C library also support +NFS, one can never make a general statement about whether all file +systems support the `_POSIX_CHOWN_RESTRICTED' and `_POSIX_NO_TRUNC' +features. So these names are never defined as macros in the GNU C +library. -`inheritsched' - Choose whether the scheduling policy and scheduling parameter for - the newly created thread are determined by the values of the - SCHEDPOLICY and SCHEDPARAM attributes (value - `PTHREAD_EXPLICIT_SCHED') or are inherited from the parent thread - (value `PTHREAD_INHERIT_SCHED'). The default is - `PTHREAD_EXPLICIT_SCHED'. + - Macro: int _POSIX_CHOWN_RESTRICTED + If this option is in effect, the `chown' function is restricted so + that the only changes permitted to nonprivileged processes is to + change the group owner of a file to either be the effective group + ID of the process, or one of its supplementary group IDs. *Note + File Owner::. -`scope' - Choose the scheduling contention scope for the created thread. The - default is `PTHREAD_SCOPE_SYSTEM', meaning that the threads contend - for CPU time with all processes running on the machine. In - particular, thread priorities are interpreted relative to the - priorities of all other processes on the machine. The other - possibility, `PTHREAD_SCOPE_PROCESS', means that scheduling - contention occurs only between the threads of the running process: - thread priorities are interpreted relative to the priorities of - the other threads of the process, regardless of the priorities of - other processes. + - Macro: int _POSIX_NO_TRUNC + If this option is in effect, file name components longer than + `NAME_MAX' generate an `ENAMETOOLONG' error.

If you - try to set the scope to this value, `pthread_attr_setscope' will - fail and return `ENOTSUP'. + - Macro: unsigned char _POSIX_VDISABLE + This option is only meaningful for files that are terminal devices. + If it is enabled, then handling for special control characters can + be disabled individually. *Note Special Characters::. -`stackaddr' - Provide an address for an application managed stack. The size of - the stack must be at least `PTHREAD_STACK_MIN'. + If one of these macros is undefined, that means that the option +might be in effect for some files and not for others. To inquire about +a particular file, call `pathconf' or `fpathconf'. *Note Pathconf::. -`stacksize' - Change the size of the stack created for the thread.

The base of the memory area is - STACKADDR with the size of the memory area, STACKSIZE, measured in - bytes. + Here are the names for the POSIX minimum upper bounds for some of the +above parameters. The significance of these values is that you can +safely push to these limits without checking whether the particular +system you are using can go that far. In most cases GNU systems do not +have these strict limitations. The actual limit should be requested if +necessary. - If the value of STACKSIZE is less than `PTHREAD_STACK_MIN', or - greater than the system's maximum stack size, or if the value of - STACKADDR lacks the proper alignment, `pthread_attr_setstack' will - fail and return `EINVAL'. +`_POSIX_LINK_MAX' + The most restrictive limit permitted by POSIX for the maximum + value of a file's link count. The value of this constant is `8'; + thus, you can always make up to eight names for a file without + running into a system limit. -`guardsize' - Change the minimum size in bytes of the guard area for the thread's - stack. The default size is a single page. If this value is set, - it will be rounded up to the nearest page size. If the value is - set to 0, a guard area will not be created for this thread. The - space allocated for the guard area is used to catch stack - overflow.

The TYPE argument is the new - cancellation type: either `PTHREAD_CANCEL_ASYNCHRONOUS' to cancel - the calling thread as soon as the cancellation request is - received, or `PTHREAD_CANCEL_DEFERRED' to keep the cancellation - request pending until the next cancellation point. If OLDTYPE is - not `NULL', the previous cancellation state is stored in the - location pointed to by OLDTYPE, and can thus be restored later by - another call to `pthread_setcanceltype'. + These functions and the associated constants for the PARAMETER +argument are declared in the header file `unistd.h'. - If the TYPE argument is not `PTHREAD_CANCEL_DEFERRED' or - `PTHREAD_CANCEL_ASYNCHRONOUS', `pthread_setcanceltype' fails and - returns `EINVAL'.

In particular, if a thread -exits or is canceled while it owns a locked mutex, the mutex will -remain locked forever and prevent other threads from executing -normally. The best way to avoid this is, just before locking the mutex, -to install a cleanup handler whose effect is to unlock the mutex. -Cleanup handlers can be used similarly to free blocks allocated with -`malloc' or close file descriptors on thread termination. + - Function: long int fpathconf (int FILEDES, int PARAMETER) + This is just like `pathconf' except that an open file descriptor + is used to specify the file for which information is requested, + instead of a file name. - Here is how to lock a mutex MUT in such a way that it will be -unlocked if the thread is canceled while MUT is locked: + The following `errno' error conditions are defined for this + function: - pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut); - pthread_mutex_lock(&mut); - /* do some work */ - pthread_mutex_unlock(&mut); - pthread_cleanup_pop(0); + `EBADF' + The FILEDES argument is not a valid file descriptor. - Equivalently, the last two lines can be replaced by + `EINVAL' + The value of PARAMETER is invalid, or the implementation + doesn't support the PARAMETER for the specific file. - pthread_cleanup_pop(1); + Here are the symbolic constants that you can use as the PARAMETER +argument to `pathconf' and `fpathconf'.

Instead, this section warns you of some of the known +trouble spots; this may help you when you try to find out what the laws +of your country are. - Unlocking the mutex and suspending on the condition variable is - done atomically. Thus, if all threads always acquire the mutex - before signaling the condition, this guarantees that the condition - cannot be signaled (and thus ignored) between the time a thread - locks the mutex and the time it waits on the condition variable. + Some countries require that you have a licence to use, possess, or +import cryptography.

Usually the bits are +numbered so that the most-significant bit, the first bit, of each block +is numbered 1. - - Function: int sem_init (sem_t *SEM, int PSHARED, unsigned int VALUE) - `sem_init' initializes the semaphore object pointed to by SEM. The - count associated with the semaphore is set initially to VALUE. The - PSHARED argument indicates whether the semaphore is local to the - current process (PSHARED is zero) or is to be shared between - several processes (PSHARED is not zero). + Under that numbering, every 8th bit of the key (the 8th, 16th, and so +on) is not used by the encryption algorithm itself. But the key must +have odd parity; that is, out of bits 1 through 8, and 9 through 16, and +so on, there must be an odd number of `1' bits, and this completely +specifies the unused bits. - On success `sem_init' returns 0. On failure it returns -1 and sets - ERRNO to one of the following values: + - Function: void setkey (const char *KEY) + The `setkey' function sets an internal data structure to be an + expanded form of KEY. KEY is specified as an array of 64 bits + each stored in a `char', the first bit is `key[0]' and the 64th + bit is `key[63]'. The KEY should have the correct parity. - `EINVAL' - VALUE exceeds the maximal counter value `SEM_VALUE_MAX' + - Function: void encrypt (char *BLOCK, int EDFLAG) + The `encrypt' function encrypts BLOCK if EDFLAG is 0, otherwise it + decrypts BLOCK, using a key previously set by `setkey'. The + result is placed in BLOCK. - `ENOSYS' - PSHARED is not zero. LinuxThreads currently does not support - process-shared semaphores. (This will eventually change.) + Like `setkey', BLOCK is specified as an array of 64 bits each + stored in a `char', but there are no parity bits in BLOCK. - - Function: int sem_destroy (sem_t * SEM) - `sem_destroy' destroys a semaphore object, freeing the resources it - might hold. If any threads are waiting on the semaphore when - `sem_destroy' is called, it fails and sets ERRNO to `EBUSY'. + - Function: void setkey_r (const char *KEY, struct crypt_data * DATA) + - Function: void encrypt_r (char *BLOCK, int EDFLAG, struct crypt_data + * DATA) + These are reentrant versions of `setkey' and `encrypt'. The only + difference is the extra parameter, which stores the expanded + version of KEY. Before calling `setkey_r' the first time, + `data->initialized' must be cleared to zero. - In the LinuxThreads implementation, no resources are associated - with semaphore objects, thus `sem_destroy' actually does nothing - except checking that no thread is waiting on the semaphore. This - will change when process-shared semaphores are implemented. + The `setkey_r' and `encrypt_r' functions are GNU extensions. +`setkey', `encrypt', `setkey_r', and `encrypt_r' are defined in +`crypt.h'. - - Function: int sem_wait (sem_t * SEM) - `sem_wait' suspends the calling thread until the semaphore pointed - to by SEM has non-zero count. It then atomically decreases the - semaphore count. + - Function: int ecb_crypt (char *KEY, char *BLOCKS, unsigned LEN, + unsigned MODE) + The function `ecb_crypt' encrypts or decrypts one or more blocks + using DES. Each block is encrypted independently. - `sem_wait' is a cancellation point. It always returns 0. + The BLOCKS and the KEY are stored packed in 8-bit bytes, so that + the first bit of the key is the most-significant bit of `key[0]' + and the 63rd bit of the key is stored as the least-significant bit + of `key[7]'. The KEY should have the correct parity. - - Function: int sem_trywait (sem_t * SEM) - `sem_trywait' is a non-blocking variant of `sem_wait'. If the - semaphore pointed to by SEM has non-zero count, the count is - atomically decreased and `sem_trywait' immediately returns 0. If - the semaphore count is zero, `sem_trywait' immediately returns -1 - and sets errno to `EAGAIN'. + LEN is the number of bytes in BLOCKS. It should be a multiple of + 8 (so that there is a whole number of blocks to encrypt). LEN is + limited to a maximum of `DES_MAXDATA' bytes. - - Function: int sem_post (sem_t * SEM) - `sem_post' atomically increases the count of the semaphore pointed - to by SEM. This function never blocks. + The result of the encryption replaces the input in BLOCKS. - On processors supporting atomic compare-and-swap (Intel 486, - Pentium and later, Alpha, PowerPC, MIPS II, Motorola 68k, - Ultrasparc), the `sem_post' function is can safely be called from - signal handlers. This is the only thread synchronization function - provided by POSIX threads that is async-signal safe. On the Intel - 386 and earlier Sparc chips, the current LinuxThreads - implementation of `sem_post' is not async-signal safe, because the - hardware does not support the required atomic operations. + The MODE parameter is the bitwise OR of two of the following: - `sem_post' always succeeds and returns 0, unless the semaphore - count would exceed `SEM_VALUE_MAX' after being incremented. In - that case `sem_post' returns -1 and sets ERRNO to `EINVAL'. The - semaphore count is left unchanged. + `DES_ENCRYPT' + This constant, used in the MODE parameter, specifies that + BLOCKS is to be encrypted. - - Function: int sem_getvalue (sem_t * SEM, int * SVAL) - `sem_getvalue' stores in the location pointed to by SVAL the - current count of the semaphore SEM. It always returns 0. + `DES_DECRYPT' + This constant, used in the MODE parameter, specifies that + BLOCKS is to be decrypted. + + `DES_HW' + This constant, used in the MODE parameter, asks to use a + hardware device. If no hardware device is available, + encryption happens anyway, but in software. + + `DES_SW' + This constant, used in the MODE parameter, specifies that no + hardware device is to be used. + + The result of the function will be one of these values: + + `DESERR_NONE' + The encryption succeeded. + + `DESERR_NOHWDEVICE' + The encryption succeeded, but there was no hardware device + available. + + `DESERR_HWERROR' + The encryption failed because of a hardware problem. + + `DESERR_BADPARAM' + The encryption failed because of a bad parameter, for + instance LEN is not a multiple of 8 or LEN is larger than + `DES_MAXDATA'. + + - Function: int DES_FAILED (int ERR) + This macro returns 1 if ERR is a `success' result code from + `ecb_crypt' or `cbc_crypt', and 0 otherwise. + + - Function: int cbc_crypt (char *KEY, char *BLOCKS, unsigned LEN, + unsigned MODE, char *IVEC) + The function `cbc_crypt' encrypts or decrypts one or more blocks + using DES in Cipher Block Chaining mode. + + For encryption in CBC mode, each block is exclusive-ored with IVEC + before being encrypted, then IVEC is replaced with the result of + the encryption, then the next block is processed. Decryption is + the reverse of this process. + + This has the advantage that blocks which are the same before being + encrypted are very unlikely to be the same after being encrypted, + making it much harder to detect patterns in the data. + + Usually, IVEC is set to 8 random bytes before encryption starts. + Then the 8 random bytes are transmitted along with the encrypted + data (without themselves being encrypted), and passed back in as + IVEC for decryption. Another possibility is to set IVEC to 8 + zeroes initially, and have the first the block encrypted consist + of 8 random bytes. + + Otherwise, all the parameters are similar to those for `ecb_crypt'. + + - Function: void des_setparity (char *KEY) + The function `des_setparity' changes the 64-bit KEY, stored packed + in 8-bit bytes, to have odd parity by altering the low bits of + each byte. + + The `ecb_crypt', `cbc_crypt', and `des_setparity' functions and +their accompanying macros are all defined in the header +`rpc/des_crypt.h'.  -File: libc.info, Node: Thread-Specific Data, Next: Threads and Signal Handling, Prev: POSIX Semaphores, Up: POSIX Threads +File: libc.info, Node: Debugging Support, Next: POSIX Threads, Prev: Cryptographic Functions, Up: Top -Thread-Specific Data -==================== +Debugging support +***************** - Programs often need global or static variables that have different -values in different threads.

Thread-specific data is the -POSIX threads answer to this need. + Applications are usually debugged using dedicated debugger programs. +But sometimes this is not possible and, in any case, it is useful to +provide the developer with as much information as possible at the time +the problems are experienced. For this reason a few functions are +provided which a program can use to help the developer more easily +locate the problem. - Each thread possesses a private memory block, the thread-specific -data area, or TSD area for short.

The value initially associated with the returned key is - `NULL' in all currently executing threads. +Backtraces +========== - The DESTR_FUNCTION argument, if not `NULL', specifies a destructor - function associated with the key. When a thread terminates via - `pthread_exit' or by cancellation, DESTR_FUNCTION is called on the - value associated with the key in that thread. The DESTR_FUNCTION - is not called if a key is deleted with `pthread_key_delete' or a - value is changed with `pthread_setspecific'. The order in which - destructor functions are called at thread termination time is - unspecified. + A "backtrace" is a list of the function calls that are currently +active in a thread. The usual way to inspect a backtrace of a program +is to use an external debugger such as gdb. However, sometimes it is +useful to obtain a backtrace programatically from within a program, +e.g., for the purposes of logging or diagnostics. - Before the destructor function is called, the `NULL' value is - associated with the key in the current thread. A destructor - function might, however, re-associate non-`NULL' values to that - key or some other key. To deal with this, if after all the - destructors have been called for all non-`NULL' values, there are - still some non-`NULL' values with associated destructors, then the - process is repeated. The LinuxThreads implementation stops the - process after `PTHREAD_DESTRUCTOR_ITERATIONS' iterations, even if - some non-`NULL' values with associated descriptors remain. Other - implementations may loop indefinitely. + The header file `execinfo.h' declares three functions that obtain +and manipulate backtraces of the current thread. - `pthread_key_create' returns 0 unless `PTHREAD_KEYS_MAX' keys have - already been allocated, in which case it fails and returns - `EAGAIN'. + - Function: int backtrace (void **BUFFER, int SIZE) + The `backtrace' function obtains a backtrace for the current + thread, as a list of pointers, and places the information into + BUFFER. The argument SIZE should be the number of `void *' + elements that will fit into BUFFER. The return value is the + actual number of entries of BUFFER that are obtained, and is at + most SIZE. - - Function: int pthread_key_delete (pthread_key_t KEY) - `pthread_key_delete' deallocates a TSD key. It does not check - whether non-`NULL' values are associated with that key in the - currently executing threads, nor call the destructor function - associated with the key. + The pointers placed in BUFFER are actually return addresses + obtained by inspecting the stack, one return address per stack + frame. - If there is no such key KEY, it returns `EINVAL'. Otherwise it - returns 0. + Note that certain compiler optimizations may interfere with + obtaining a valid backtrace. Function inlining causes the inlined + function to not have a stack frame; tail call optimization + replaces one stack frame with another; frame pointer elimination + will stop `backtrace' from interpreting the stack contents + correctly. - - Function: int pthread_setspecific (pthread_key_t KEY, const void - *POINTER) - `pthread_setspecific' changes the value associated with KEY in the - calling thread, storing the given POINTER instead. + - Function: char ** backtrace_symbols (void *const *BUFFER, int SIZE) + The `backtrace_symbols' function translates the information + obtained from the `backtrace' function into an array of strings. + The argument BUFFER should be a pointer to an array of addresses + obtained via the `backtrace' function, and SIZE is the number of + entries in that array (the return value of `backtrace'). - If there is no such key KEY, it returns `EINVAL'. Otherwise it - returns 0. + The return value is a pointer to an array of strings, which has + SIZE entries just like the array BUFFER. Each string contains a + printable representation of the corresponding element of BUFFER. + It includes the function name (if this can be determined), an + offset into the function, and the actual return address (in + hexadecimal). - - Function: void * pthread_getspecific (pthread_key_t KEY) - `pthread_getspecific' returns the value currently associated with - KEY in the calling thread. + Currently, the function name and offset only be obtained on + systems that use the ELF binary format for programs and libraries. + On other systems, only the hexadecimal return address will be + present. Also, you may need to pass additional flags to the + linker to make the function names available to the program. (For + example, on systems using GNU ld, you must pass (`-rdynamic'.) - If there is no such key KEY, it returns `NULL'. + The return value of `backtrace_symbols' is a pointer obtained via + the `malloc' function, and it is the responsibility of the caller + to `free' that pointer. Note that only the return value need be + freed, not the individual strings. - The following code fragment allocates a thread-specific array of 100 -characters, with automatic reclaimation at thread exit: + The return value is `NULL' if sufficient memory for the strings + cannot be obtained. - /* Key for the thread-specific buffer */ - static pthread_key_t buffer_key; - - /* Once-only initialisation of the key */ - static pthread_once_t buffer_key_once = PTHREAD_ONCE_INIT; + - Function: void backtrace_symbols_fd (void *const *BUFFER, int SIZE, + int FD) + The `backtrace_symbols_fd' function performs the same translation + as the function `backtrace_symbols' function.

But if you can arrange to check less often, or check +more efficiently, then you make the program faster. + + The function `obstack_room' returns the amount of room available in +the current chunk.

The new thread calls the + function START_ROUTINE, passing it ARG as first argument. The new + thread terminates either explicitly, by calling `pthread_exit', or + implicitly, by returning from the START_ROUTINE function. The + latter case is equivalent to calling `pthread_exit' with the result + returned by START_ROUTINE as exit code. - One or more of the three handlers PREPARE, PARENT and CHILD can be - given as `NULL', meaning that no handler needs to be called at the - corresponding point. + The ATTR argument specifies thread attributes to be applied to the + new thread. *Note Thread Attributes::, for details. The ATTR + argument can also be `NULL', in which case default attributes are + used: the created thread is joinable (not detached) and has an + ordinary (not realtime) scheduling policy. - `pthread_atfork' can be called several times to install several - sets of handlers. At `fork' time, the PREPARE handlers are called - in LIFO order (last added with `pthread_atfork', first called - before `fork'), while the PARENT and CHILD handlers are called in - FIFO order (first added, first called). + On success, the identifier of the newly created thread is stored + in the location pointed by the THREAD argument, and a 0 is + returned. On error, a non-zero error code is returned. - If there is insufficient memory available to register the handlers, - `pthread_atfork' fails and returns `ENOMEM'. Otherwise it returns - 0. + This function may return the following errors: + `EAGAIN' + Not enough system resources to create a process for the new + thread, or more than `PTHREAD_THREADS_MAX' threads are + already active. - The functions `fork' and `pthread_atfork' must not be regarded as - reentrant from the context of the handlers. That is to say, if a - `pthread_atfork' handler invoked from within `fork' calls - `pthread_atfork' or `fork', the behavior is undefined. + - Function: void pthread_exit (void *RETVAL) + `pthread_exit' terminates the execution of the calling thread. All + cleanup handlers (*note Cleanup Handlers::) that have been set for + the calling thread with `pthread_cleanup_push' are executed in + reverse order (the most recently pushed handler is executed + first). Finalization functions for thread-specific data are then + called for all keys that have non-`NULL' values associated with + them in the calling thread (*note Thread-Specific Data::). + Finally, execution of the calling thread is stopped. - Registering a triplet of handlers is an atomic operation with - respect to fork. If new handlers are registered at about the same - time as a fork occurs, either all three handlers will be called, - or none of them will be called. + The RETVAL argument is the return value of the thread. It can be + retrieved from another thread using `pthread_join'. - The handlers are inherited by the child process, and there is no - way to remove them, short of using `exec' to load a new pocess - image. + The `pthread_exit' function never returns. + - Function: int pthread_cancel (pthread_t THREAD) + `pthread_cancel' sends a cancellation request to the thread denoted + by the THREAD argument. If there is no such thread, + `pthread_cancel' fails and returns `ESRCH'. Otherwise it returns + 0. *Note Cancellation::, for details. - To understand the purpose of `pthread_atfork', recall that `fork' -duplicates the whole memory space, including mutexes in their current -locking state, but only the calling thread: other threads are not -running in the child process. Thus, if a mutex is locked by a thread -other than the thread calling `fork', that mutex will remain locked -forever in the child process, possibly blocking the execution of the -child process. Or if some shared data, such as a linked list, was in the -middle of being updated by a thread in the parent process, the child -will get a copy of the incompletely updated data which it cannot use. + - Function: int pthread_join (pthread_t TH, void **thread_RETURN) + `pthread_join' suspends the execution of the calling thread until + the thread identified by TH terminates, either by calling + `pthread_exit' or by being canceled. - To avoid this, install handlers with `pthread_atfork' as follows: -have the PREPARE handler lock the mutexes (in locking order), and the -PARENT handler unlock the mutexes. The CHILD handler should reset the -mutexes using `pthread_mutex_init', as well as any other -synchronization objects such as condition variables. + If THREAD_RETURN is not `NULL', the return value of TH is stored + in the location pointed to by THREAD_RETURN. The return value of + TH is either the argument it gave to `pthread_exit', or + `PTHREAD_CANCELED' if TH was canceled. - Locking the global mutexes before the fork ensures that all other -threads are locked out of the critical regions of code protected by -those mutexes. Thus when `fork' takes a snapshot of the parent's -address space, that snapshot will copy valid, stable data. Resetting -the synchronization objects in the child process will ensure they are -properly cleansed of any artifacts from the threading subsystem of the -parent process. For example, a mutex may inherit a wait queue of -threads waiting for the lock; this wait queue makes no sense in the -child process. Initializing the mutex takes care of this. + The joined thread `th' must be in the joinable state: it must not + have been detached using `pthread_detach' or the + `PTHREAD_CREATE_DETACHED' attribute to `pthread_create'. - -File: libc.info, Node: Streams and Fork, Next: Miscellaneous Thread Functions, Prev: Threads and Fork, Up: POSIX Threads + When a joinable thread terminates, its memory resources (thread + descriptor and stack) are not deallocated until another thread + performs `pthread_join' on it. Therefore, `pthread_join' must be + called once for each joinable thread created to avoid memory leaks. -Streams and Fork -================ + At most one thread can wait for the termination of a given thread. + Calling `pthread_join' on a thread TH on which another thread is + already waiting for termination returns an error. - The GNU standard I/O library has an internal mutex which guards the -internal linked list of all standard C FILE objects. This mutex is -properly taken care of during `fork' so that the child receives an -intact copy of the list. This allows the `fopen' function, and related -stream-creating functions, to work correctly in the child process, -since these functions need to insert into the list. + `pthread_join' is a cancellation point. If a thread is canceled + while suspended in `pthread_join', the thread execution resumes + immediately and the cancellation is executed without waiting for + the TH thread to terminate. If cancellation occurs during + `pthread_join', the TH thread remains not joined. - However, the individual stream locks are not completely taken care -of. Thus unless the multithreaded application takes special -precautions in its use of `fork', the child process might not be able -to safely use the streams that it inherited from the parent. In -general, for any given open stream in the parent that is to be used by -the child process, the application must ensure that that stream is not -in use by another thread when `fork' is called. Otherwise an -inconsistent copy of the stream object be produced. An easy way to -ensure this is to use `flockfile' to lock the stream prior to calling -`fork' and then unlock it with `funlockfile' inside the parent process, -provided that the parent's threads properly honor these locks. Nothing -special needs to be done in the child process, since the library -internally resets all stream locks. + On success, the return value of TH is stored in the location + pointed to by THREAD_RETURN, and 0 is returned. On error, one of + the following values is returned: + `ESRCH' + No thread could be found corresponding to that specified by + TH. - Note that the stream locks are not shared between the parent and -child.

These kinds of checks are helpful in debugging -problems with the interfaces between different parts of the program, -for example. +Cancellation +============ - The `assert' macro, defined in the header file `assert.h', provides -a convenient way to abort the program while printing a message about -where in the program the error was detected. + Cancellation is the mechanism by which a thread can terminate the +execution of another thread. More precisely, a thread can send a +cancellation request to another thread. Depending on its settings, the +target thread can then either ignore the request, honor it immediately, +or defer it till it reaches a cancellation point. When threads are +first created by `pthread_create', they always defer cancellation +requests. - Once you think your program is debugged, you can disable the error -checks performed by the `assert' macro by recompiling with the macro -`NDEBUG' defined. This means you don't actually have to change the -program source code to disable these checks. + When a thread eventually honors a cancellation request, it behaves +as if `pthread_exit(PTHREAD_CANCELED)' was called. All cleanup handlers +are executed in reverse order, finalization functions for +thread-specific data are called, and finally the thread stops executing. +If the canceled thread was joinable, the return value +`PTHREAD_CANCELED' is provided to whichever thread calls PTHREAD_JOIN +on it. See `pthread_exit' for more information. - But disabling these consistency checks is undesirable unless they -make the program significantly slower. All else being equal, more error -checking is good no matter who is running the program. A wise user -would rather have a program crash, visibly, than have it return nonsense -without indicating anything might be wrong. + Cancellation points are the points where the thread checks for +pending cancellation requests and performs them. The POSIX threads +functions `pthread_join', `pthread_cond_wait', +`pthread_cond_timedwait', `pthread_testcancel', `sem_wait', and +`sigwait' are cancellation points.

Otherwise it returns 0. - *Warning:* Even the argument expression EXPRESSION is not - evaluated if `NDEBUG' is in effect. So never use `assert' with - arguments that involve side effects.

If OLDTYPE is + not `NULL', the previous cancellation state is stored in the + location pointed to by OLDTYPE, and can thus be restored later by + another call to `pthread_setcanceltype'. - Sometimes the "impossible" condition you want to check for is an -error return from an operating system function.

Not only are the semantics +tricky, but you may need to write code that does the right thing at +fork time even if that code doesn't use the `fork' function. Moreover, +you need to be aware of interaction between `fork' and some library +features like `pthread_once' and stdio streams. - You are probably already familiar with most of these concepts in -terms of scientific or exponential notation for floating point numbers. -For example, the number `123456.0' could be expressed in exponential -notation as `1.23456e+05', a shorthand notation indicating that the -mantissa `1.23456' is multiplied by the base `10' raised to power `5'. + When `fork' is called by one of the threads of a process, it creates +a new process which is copy of the calling process. Effectively, in +addition to copying certain system objects, the function takes a +snapshot of the memory areas of the parent process, and creates +identical areas in the child. To make matters more complicated, with +threads it's possible for two or more threads to concurrently call fork +to create two or more child processes. - More formally, the internal representation of a floating point number -can be characterized in terms of the following parameters: + The child process has a copy of the address space of the parent, but +it does not inherit any of its threads. Execution of the child process +is carried out by a new thread which returns from `fork' function with +a return value of zero; it is the only thread in the child process. +Because threads are not inherited across fork, issues arise. At the +time of the call to `fork', threads in the parent process other than +the one calling `fork' may have been executing critical regions of +code. As a result, the child process may get a copy of objects that +are not in a well-defined state. This potential problem affects all +components of the program. - * The "sign" is either `-1' or `1'. + Any program component which will continue being used in a child +process must correctly handle its state during `fork'. For this +purpose, the POSIX interface provides the special function +`pthread_atfork' for installing pointers to handler functions which are +called from within `fork'. - * The "base" or "radix" for exponentiation, an integer greater than - `1'. This is a constant for a particular representation. + - Function: int pthread_atfork (void (*PREPARE)(void), void + (*PARENT)(void), void (*CHILD)(void)) + `pthread_atfork' registers handler functions to be called just + before and just after a new process is created with `fork'. The + PREPARE handler will be called from the parent process, just + before the new process is created. The PARENT handler will be + called from the parent process, just before `fork' returns. The + CHILD handler will be called from the child process, just before + `fork' returns. - * The "exponent" to which the base is raised. The upper and lower - bounds of the exponent value are constants for a particular - representation. + `pthread_atfork' returns 0 on success and a non-zero error code on + error. - Sometimes, in the actual bits representing the floating point - number, the exponent is "biased" by adding a constant to it, to - make it always be represented as an unsigned quantity. This is - only important if you have some reason to pick apart the bit - fields making up the floating point number by hand, which is - something for which the GNU library provides no support. So this - is ignored in the discussion that follows. + One or more of the three handlers PREPARE, PARENT and CHILD can be + given as `NULL', meaning that no handler needs to be called at the + corresponding point. - * The "mantissa" or "significand" is an unsigned integer which is a - part of each floating point number. + `pthread_atfork' can be called several times to install several + sets of handlers. At `fork' time, the PREPARE handlers are called + in LIFO order (last added with `pthread_atfork', first called + before `fork'), while the PARENT and CHILD handlers are called in + FIFO order (first added, first called). - * The "precision" of the mantissa. If the base of the representation - is B, then the precision is the number of base-B digits in the - mantissa. This is a constant for a particular representation. + If there is insufficient memory available to register the handlers, + `pthread_atfork' fails and returns `ENOMEM'. Otherwise it returns + 0. - Many floating point representations have an implicit "hidden bit" - in the mantissa. This is a bit which is present virtually in the - mantissa, but not stored in memory because its value is always 1 - in a normalized number. The precision figure (see above) includes - any hidden bits. + The functions `fork' and `pthread_atfork' must not be regarded as + reentrant from the context of the handlers. That is to say, if a + `pthread_atfork' handler invoked from within `fork' calls + `pthread_atfork' or `fork', the behavior is undefined. - Again, the GNU library provides no facilities for dealing with such - low-level aspects of the representation. + Registering a triplet of handlers is an atomic operation with + respect to fork. If new handlers are registered at about the same + time as a fork occurs, either all three handlers will be called, + or none of them will be called. - The mantissa of a floating point number represents an implicit -fraction whose denominator is the base raised to the power of the -precision. Since the largest representable mantissa is one less than -this denominator, the value of the fraction is always strictly less -than `1'. The mathematical value of a floating point number is then -the product of this fraction, the sign, and the base raised to the -exponent. + The handlers are inherited by the child process, and there is no + way to remove them, short of using `exec' to load a new pocess + image. - We say that the floating point number is "normalized" if the -fraction is at least `1/B', where B is the base. In other words, the -mantissa would be too large to fit if it were multiplied by the base. -Non-normalized numbers are sometimes called "denormal"; they contain -less precision than the representation normally can hold. - If the number is not normalized, then you can subtract `1' from the -exponent while multiplying the mantissa by the base, and get another -floating point number with the same value. "Normalization" consists of -doing this repeatedly until the number is normalized. Two distinct -normalized floating point numbers cannot be equal in value. + To understand the purpose of `pthread_atfork', recall that `fork' +duplicates the whole memory space, including mutexes in their current +locking state, but only the calling thread: other threads are not +running in the child process. Thus, if a mutex is locked by a thread +other than the thread calling `fork', that mutex will remain locked +forever in the child process, possibly blocking the execution of the +child process. Or if some shared data, such as a linked list, was in the +middle of being updated by a thread in the parent process, the child +will get a copy of the incompletely updated data which it cannot use. - (There is an exception to this rule: if the mantissa is zero, it is -considered normalized. Another exception happens on certain machines -where the exponent is as small as the representation can hold. Then it -is impossible to subtract `1' from the exponent, so a number may be -normalized even if its fraction is less than `1/B'.) + To avoid this, install handlers with `pthread_atfork' as follows: +have the PREPARE handler lock the mutexes (in locking order), and the +PARENT handler unlock the mutexes. The CHILD handler should reset the +mutexes using `pthread_mutex_init', as well as any other +synchronization objects such as condition variables. + + Locking the global mutexes before the fork ensures that all other +threads are locked out of the critical regions of code protected by +those mutexes. Thus when `fork' takes a snapshot of the parent's +address space, that snapshot will copy valid, stable data. Resetting +the synchronization objects in the child process will ensure they are +properly cleansed of any artifacts from the threading subsystem of the +parent process. For example, a mutex may inherit a wait queue of +threads waiting for the lock; this wait queue makes no sense in the +child process. Initializing the mutex takes care of this.  -File: libc.info, Node: Floating Point Parameters, Next: IEEE Floating Point, Prev: Floating Point Concepts, Up: Floating Type Macros +File: libc.info, Node: Streams and Fork, Next: Miscellaneous Thread Functions, Prev: Threads and Fork, Up: POSIX Threads -Floating Point Parameters -......................... +Streams and Fork +================ - These macro definitions can be accessed by including the header file -`float.h' in your program. + The GNU standard I/O library has an internal mutex which guards the +internal linked list of all standard C FILE objects. This mutex is +properly taken care of during `fork' so that the child receives an +intact copy of the list. This allows the `fopen' function, and related +stream-creating functions, to work correctly in the child process, +since these functions need to insert into the list. - Macro names starting with `FLT_' refer to the `float' type, while -names beginning with `DBL_' refer to the `double' type and names -beginning with `LDBL_' refer to the `long double' type. (If GCC does -not support `long double' as a distinct data type on a target machine -then the values for the `LDBL_' constants are equal to the -corresponding constants for the `double' type.) + However, the individual stream locks are not completely taken care +of. Thus unless the multithreaded application takes special +precautions in its use of `fork', the child process might not be able +to safely use the streams that it inherited from the parent. In +general, for any given open stream in the parent that is to be used by +the child process, the application must ensure that that stream is not +in use by another thread when `fork' is called. Otherwise an +inconsistent copy of the stream object be produced. An easy way to +ensure this is to use `flockfile' to lock the stream prior to calling +`fork' and then unlock it with `funlockfile' inside the parent process, +provided that the parent's threads properly honor these locks. Nothing +special needs to be done in the child process, since the library +internally resets all stream locks. - Of these macros, only `FLT_RADIX' is guaranteed to be a constant -expression. The other macros listed here cannot be reliably used in -places that require constant expressions, such as `#if' preprocessing -directives or in the dimensions of static arrays. + Note that the stream locks are not shared between the parent and +child. For example, even if you ensure that, say, the stream `stdout' +is properly treated and can be safely used in the child, the stream +locks do not provide an exclusion mechanism between the parent and +child. If both processes write to `stdout', strangely interleaved +output may result regardless of the explicit use of `flockfile' or +implicit locks. - Although the ISO C standard specifies minimum and maximum values for -most of these parameters, the GNU C implementation uses whatever values -describe the floating point representation of the target machine. So in -principle GNU C actually satisfies the ISO C requirements only if the -target machine is suitable. In practice, all the machines currently -supported are suitable. + Also note that these provisions are a GNU extension; other systems +might not provide any way for streams to be used in the child of a +multithreaded process. POSIX requires that such a child process +confines itself to calling only asynchronous safe functions, which +excludes much of the library, including standard I/O. -`FLT_ROUNDS' - This value characterizes the rounding mode for floating point - addition. The following values indicate standard rounding modes: + +File: libc.info, Node: Miscellaneous Thread Functions, Prev: Streams and Fork, Up: POSIX Threads - `-1' - The mode is indeterminable. +Miscellaneous Thread Functions +============================== - `0' - Rounding is towards zero. + - Function: pthread_t pthread_self (VOID) + `pthread_self' returns the thread identifier for the calling + thread. - `1' - Rounding is to the nearest number. + - Function: int pthread_equal (pthread_t thread1, pthread_t thread2) + `pthread_equal' determines if two thread identifiers refer to the + same thread. - `2' - Rounding is towards positive infinity. + A non-zero value is returned if THREAD1 and THREAD2 refer to the + same thread. Otherwise, 0 is returned. - `3' - Rounding is towards negative infinity. + - Function: int pthread_detach (pthread_t TH) + `pthread_detach' puts the thread TH in the detached state. This + guarantees that the memory resources consumed by TH will be freed + immediately when TH terminates. However, this prevents other + threads from synchronizing on the termination of TH using + `pthread_join'. - Any other value represents a machine-dependent nonstandard rounding - mode. + A thread can be created initially in the detached state, using the + `detachstate' attribute to `pthread_create'.

When you +define a function, you specify the data type for each argument. Every +call to the function should supply the expected number of arguments, +with types that can be converted to the specified ones. Thus, if the +function `foo' is declared with `int foo (int, char *);' then you must +call it with two arguments, a number (any kind will do) and a string +pointer. + + But some functions perform operations that can meaningfully accept an +unlimited number of arguments. + + In some cases a function can handle any number of values by +operating on all of them as a block. For example, consider a function +that allocates a one-dimensional array with `malloc' to hold a +specified set of values. This operation makes sense for any number of +values, as long as the length of the array corresponds to that number. +Without facilities for variable arguments, you would have to define a +separate function for each possible array size. + + The library function `printf' (*note Formatted Output::) is an +example of another class of function where variable arguments are +useful. This function prints its arguments (which can vary in type as +well as number) under the control of a format template string. + + These are good reasons to define a "variadic" function which can +handle as many arguments as the caller chooses to pass. + + Some functions such as `open' take a fixed set of arguments, but +occasionally ignore the last few. Strict adherence to ISO C requires +these functions to be defined as variadic; in practice, however, the GNU +C compiler and most other C compilers let you define such a function to +take a fixed set of arguments--the most it can ever use--and then only +_declare_ the function as variadic (or not declare its arguments at +all!). + + +File: libc.info, Node: How Variadic, Next: Variadic Example, Prev: Why Variadic, Up: Variadic Functions + +How Variadic Functions are Defined and Used +------------------------------------------- + + Defining and using a variadic function involves three steps: + + * _Define_ the function as variadic, using an ellipsis (`...') in + the argument list, and using special macros to access the variable + arguments. *Note Receiving Arguments::. + + * _Declare_ the function as variadic, using a prototype with an + ellipsis (`...'), in all the files which call it. *Note Variadic + Prototypes::. + + * _Call_ the function by writing the fixed arguments followed by the + additional variable arguments. *Note Calling Variadics::. + +* Menu: + +* Variadic Prototypes:: How to make a prototype for a function + with variable arguments. +* Receiving Arguments:: Steps you must follow to access the + optional argument values. +* How Many Arguments:: How to decide whether there are more arguments. +* Calling Variadics:: Things you need to know about calling + variable arguments functions. +* Argument Macros:: Detailed specification of the macros + for accessing variable arguments. +* Old Varargs:: The pre-ISO way of defining variadic functions. + + +File: libc.info, Node: Variadic Prototypes, Next: Receiving Arguments, Up: How Variadic + +Syntax for Variable Arguments +............................. + + A function that accepts a variable number of arguments must be +declared with a prototype that says so. You write the fixed arguments +as usual, and then tack on `...' to indicate the possibility of +additional arguments. The syntax of ISO C requires at least one fixed +argument before the `...'. For example, + + int + func (const char *a, int b, ...) + { + ... + } + +defines a function `func' which returns an `int' and takes two required +arguments, a `const char *' and an `int'. These are followed by any +number of anonymous arguments. + + *Portability note:* For some C compilers, the last required argument +must not be declared `register' in the function definition. +Furthermore, this argument's type must be "self-promoting": that is, +the default promotions must not change its type. This rules out array +and function types, as well as `float', `char' (whether signed or not) +and `short int' (whether signed or not). This is actually an ISO C +requirement. + + +File: libc.info, Node: Receiving Arguments, Next: How Many Arguments, Prev: Variadic Prototypes, Up: How Variadic + +Receiving the Argument Values +............................. + + Ordinary fixed arguments have individual names, and you can use these +names to access their values. But optional arguments have no +names--nothing but `...'. How can you access them? + + The only way to access them is sequentially, in the order they were +written, and you must use special macros from `stdarg.h' in the +following three step process: + + 1. You initialize an argument pointer variable of type `va_list' using + `va_start'. The argument pointer when initialized points to the + first optional argument. + + 2. You access the optional arguments by successive calls to `va_arg'. + The first call to `va_arg' gives you the first optional argument, + the next call gives you the second, and so on. + + You can stop at any time if you wish to ignore any remaining + optional arguments. It is perfectly all right for a function to + access fewer arguments than were supplied in the call, but you + will get garbage values if you try to access too many arguments. + + 3. You indicate that you are finished with the argument pointer + variable by calling `va_end'. + + (In practice, with most C compilers, calling `va_end' does nothing. + This is always true in the GNU C compiler. But you might as well + call `va_end' just in case your program is someday compiled with a + peculiar compiler.) + + *Note Argument Macros::, for the full definitions of `va_start', +`va_arg' and `va_end'. + + Steps 1 and 3 must be performed in the function that accepts the +optional arguments. However, you can pass the `va_list' variable as an +argument to another function and perform all or part of step 2 there. + + You can perform the entire sequence of three steps multiple times +within a single function invocation. If you want to ignore the optional +arguments, you can do these steps zero times. + + You can have more than one argument pointer variable if you like. +You can initialize each variable with `va_start' when you wish, and +then you can fetch arguments with each argument pointer as you wish. +Each argument pointer variable will sequence through the same set of +argument values, but at its own pace. + + *Portability note:* With some compilers, once you pass an argument +pointer value to a subroutine, you must not keep using the same +argument pointer value after that subroutine returns. For full +portability, you should just pass it to `va_end'. This is actually an +ISO C requirement, but most ANSI C compilers work happily regardless. + + +File: libc.info, Node: How Many Arguments, Next: Calling Variadics, Prev: Receiving Arguments, Up: How Variadic + +How Many Arguments Were Supplied +................................ + + There is no general way for a function to determine the number and +type of the optional arguments it was called with. So whoever designs +the function typically designs a convention for the caller to specify +the number and type of arguments. It is up to you to define an +appropriate calling convention for each variadic function, and write +all calls accordingly. + + One kind of calling convention is to pass the number of optional +arguments as one of the fixed arguments. This convention works provided +all of the optional arguments are of the same type. + + A similar alternative is to have one of the required arguments be a +bit mask, with a bit for each possible purpose for which an optional +argument might be supplied. You would test the bits in a predefined +sequence; if the bit is set, fetch the value of the next argument, +otherwise use a default value. + + A required argument can be used as a pattern to specify both the +number and types of the optional arguments. The format string argument +to `printf' is one example of this (*note Formatted Output Functions::). + + Another possibility is to pass an "end marker" value as the last +optional argument. For example, for a function that manipulates an +arbitrary number of pointer arguments, a null pointer might indicate the +end of the argument list. (This assumes that a null pointer isn't +otherwise meaningful to the function.) The `execl' function works in +just this way; see *Note Executing a File::. + + +File: libc.info, Node: Calling Variadics, Next: Argument Macros, Prev: How Many Arguments, Up: How Variadic + +Calling Variadic Functions +.......................... + + You don't have to do anything special to call a variadic function. +Just put the arguments (required arguments, followed by optional ones) +inside parentheses, separated by commas, as usual. But you must declare +the function with a prototype and know how the argument values are +converted. + + In principle, functions that are _defined_ to be variadic must also +be _declared_ to be variadic using a function prototype whenever you +call them. (*Note Variadic Prototypes::, for how.) This is because +some C compilers use a different calling convention to pass the same set +of argument values to a function depending on whether that function +takes variable arguments or fixed arguments. + + In practice, the GNU C compiler always passes a given set of argument +types in the same way regardless of whether they are optional or +required. So, as long as the argument types are self-promoting, you can +safely omit declaring them. Usually it is a good idea to declare the +argument types for variadic functions, and indeed for all functions. +But there are a few functions which it is extremely convenient not to +have to declare as variadic--for example, `open' and `printf'. + + Since the prototype doesn't specify types for optional arguments, in +a call to a variadic function the "default argument promotions" are +performed on the optional argument values. This means the objects of +type `char' or `short int' (whether signed or not) are promoted to +either `int' or `unsigned int', as appropriate; and that objects of +type `float' are promoted to type `double'. So, if the caller passes a +`char' as an optional argument, it is promoted to an `int', and the +function can access it with `va_arg (AP, int)'. + + Conversion of the required arguments is controlled by the function +prototype in the usual way: the argument expression is converted to the +declared argument type as if it were being assigned to a variable of +that type. + + +File: libc.info, Node: Argument Macros, Next: Old Varargs, Prev: Calling Variadics, Up: How Variadic + +Argument Access Macros +...................... + + Here are descriptions of the macros used to retrieve variable +arguments.

TYPE must be a self-promoting type (not `char' or + `short int' or `float') that matches the type of the actual + argument. + + - Macro: void va_end (va_list AP) + This ends the use of AP. After a `va_end' call, further `va_arg' + calls with the same AP may not work. You should invoke `va_end' + before returning from the function in which `va_start' was invoked + with the same AP argument. + + In the GNU C library, `va_end' does nothing, and you need not ever + use it except for reasons of portability. + + + Sometimes it is necessary to parse the list of parameters more than +once or one wants to remember a certain position in the parameter list. +To do this, one will have to make a copy of the current value of the +argument. But `va_list' is an opaque type and one cannot necessarily +assign the value of one variable of type `va_list' to another variable +of the same type. + + - Macro: void __va_copy (va_list DEST, va_list SRC) + The `__va_copy' macro allows copying of objects of type `va_list' + even if this is not an integral type.

The GNU C compiler still supports it; +currently, it is more portable than the ISO C facility, since support +for ISO C is still not universal. The header file which defines the +old-fashioned variadic facility is called `varargs.h'. + + Using `varargs.h' is almost the same as using `stdarg.h'. There is +no difference in how you call a variadic function; see *Note Calling +Variadics::. The only difference is in how you define them. First of +all, you must use old-style non-prototype syntax, like this: + + tree + build (va_alist) + va_dcl + { + + Secondly, you must give `va_start' only one argument, like this: + + va_list p; + va_start (p); + + These are the special macros used for defining old-style variadic +functions: + + - Macro: va_alist + This macro stands for the argument name list required in a variadic + function. + + - Macro: va_dcl + This macro declares the implicit argument or arguments for a + variadic function. + + - Macro: void va_start (va_list AP) + This macro, as defined in `varargs.h', initializes the argument + pointer variable AP to point to the first argument of the current + function. + + The other argument macros, `va_arg' and `va_end', are the same in +`varargs.h' as in `stdarg.h'; see *Note Argument Macros::, for details. + + It does not work to include both `varargs.h' and `stdarg.h' in the +same compilation; they define `va_start' in conflicting ways. + + +File: libc.info, Node: Null Pointer Constant, Next: Important Data Types, Prev: Variadic Functions, Up: Language Features + +Null Pointer Constant +===================== + + The null pointer constant is guaranteed not to point to any real +object. You can assign it to any pointer variable since it has type +`void *'. The preferred way to write a null pointer constant is with +`NULL'. + + - Macro: void * NULL + This is a null pointer constant. + + You can also use `0' or `(void *)0' as a null pointer constant, but +using `NULL' is cleaner because it makes the purpose of the constant +more evident. + + If you use the null pointer constant as a function argument, then for +complete portability you should make sure that the function has a +prototype declaration. Otherwise, if the target machine has two +different pointer representations, the compiler won't know which +representation to use for that argument. You can avoid the problem by +explicitly casting the constant to the proper pointer type, but we +recommend instead adding a prototype for the function you are calling. + + +File: libc.info, Node: Important Data Types, Next: Data Type Measurements, Prev: Null Pointer Constant, Up: Language Features + +Important Data Types +==================== + + The result of subtracting two pointers in C is always an integer, +but the precise data type varies from C compiler to C compiler. +Likewise, the data type of the result of `sizeof' also varies between +compilers. ISO defines standard aliases for these two types, so you +can refer to them in a portable fashion. They are defined in the +header file `stddef.h'. + + - Data Type: ptrdiff_t + This is the signed integer type of the result of subtracting two + pointers. For example, with the declaration `char *p1, *p2;', the + expression `p2 - p1' is of type `ptrdiff_t'. This will probably + be one of the standard signed integer types (`short int', `int' or + `long int'), but might be a nonstandard type that exists only for + this purpose. + + - Data Type: size_t + This is an unsigned integer type used to represent the sizes of + objects. The result of the `sizeof' operator is of this type, and + functions such as `malloc' (*note Unconstrained Allocation::) and + `memcpy' (*note Copying and Concatenation::) accept arguments of + this type to specify object sizes. + + *Usage Note:* `size_t' is the preferred way to declare any + arguments or variables that hold the size of an object. + + In the GNU system `size_t' is equivalent to either `unsigned int' or +`unsigned long int'. These types have identical properties on the GNU +system and, for most purposes, you can use them interchangeably. +However, they are distinct as data types, which makes a difference in +certain contexts. + + For example, when you specify the type of a function argument in a +function prototype, it makes a difference which one you use. If the +system header files declare `malloc' with an argument of type `size_t' +and you declare `malloc' with an argument of type `unsigned int', you +will get a compilation error if `size_t' happens to be `unsigned long +int' on your system. To avoid any possibility of error, when a +function argument or value is supposed to have type `size_t', never +declare its type in any other way. + + *Compatibility Note:* Implementations of C before the advent of +ISO C generally used `unsigned int' for representing object sizes and +`int' for pointer subtraction results. They did not necessarily define +either `size_t' or `ptrdiff_t'. Unix systems did define `size_t', in +`sys/types.h', but the definition was usually a signed type. + + +File: libc.info, Node: Data Type Measurements, Prev: Important Data Types, Up: Language Features + +Data Type Measurements +====================== + + Most of the time, if you choose the proper C data type for each +object in your program, you need not be concerned with just how it is +represented or how many bits it uses. When you do need such +information, the C language itself does not provide a way to get it. +The header files `limits.h' and `float.h' contain macros which give you +this information in full detail. + +* Menu: + +* Width of Type:: How many bits does an integer type hold? +* Range of Type:: What are the largest and smallest values + that an integer type can hold? +* Floating Type Macros:: Parameters that measure the floating point types. +* Structure Measurement:: Getting measurements on structure types. + + +File: libc.info, Node: Width of Type, Next: Range of Type, Up: Data Type Measurements + +Computing the Width of an Integer Data Type +------------------------------------------- + + The most common reason that a program needs to know how many bits +are in an integer type is for using an array of `long int' as a bit +vector. You can access the bit at index N with + + vector[N / LONGBITS] & (1 << (N % LONGBITS)) + +provided you define `LONGBITS' as the number of bits in a `long int'. + + There is no operator in the C language that can give you the number +of bits in an integer data type. But you can compute it from the macro +`CHAR_BIT', defined in the header file `limits.h'. + +`CHAR_BIT' + This is the number of bits in a `char'--eight, on most systems. + The value has type `int'. + + You can compute the number of bits in any data type TYPE like this: + + sizeof (TYPE) * CHAR_BIT + + +File: libc.info, Node: Range of Type, Next: Floating Type Macros, Prev: Width of Type, Up: Data Type Measurements + +Range of an Integer Type +------------------------ + + Suppose you need to store an integer value which can range from zero +to one million. Which is the smallest type you can use? There is no +general rule; it depends on the C compiler and target machine. You can +use the `MIN' and `MAX' macros in `limits.h' to determine which type +will work. + + Each signed integer type has a pair of macros which give the smallest +and largest values that it can hold. Each unsigned integer type has one +such macro, for the maximum value; the minimum value is, of course, +zero. + + The values of these macros are all integer constant expressions. The +`MAX' and `MIN' macros for `char' and `short int' types have values of +type `int'. The `MAX' and `MIN' macros for the other types have values +of the same type described by the macro--thus, `ULONG_MAX' has type +`unsigned long int'. + +`SCHAR_MIN' + This is the minimum value that can be represented by a + `signed char'. + +`SCHAR_MAX' +`UCHAR_MAX' + These are the maximum values that can be represented by a + `signed char' and `unsigned char', respectively. + +`CHAR_MIN' + This is the minimum value that can be represented by a `char'. + It's equal to `SCHAR_MIN' if `char' is signed, or zero otherwise. + +`CHAR_MAX' + This is the maximum value that can be represented by a `char'. + It's equal to `SCHAR_MAX' if `char' is signed, or `UCHAR_MAX' + otherwise. + +`SHRT_MIN' + This is the minimum value that can be represented by a + `signed short int'. On most machines that the GNU C library runs + on, `short' integers are 16-bit quantities. + +`SHRT_MAX' +`USHRT_MAX' + These are the maximum values that can be represented by a + `signed short int' and `unsigned short int', respectively. + +`INT_MIN' + This is the minimum value that can be represented by a + `signed int'.

`termios.h' (POSIX.1): *Note Control Modes::. + You are probably already familiar with most of these concepts in +terms of scientific or exponential notation for floating point numbers. +For example, the number `123456.0' could be expressed in exponential +notation as `1.23456e+05', a shorthand notation indicating that the +mantissa `1.23456' is multiplied by the base `10' raised to power `5'. -`complex double csin (complex double Z)' - `complex.h' (ISO): *Note Trig Functions::. + More formally, the internal representation of a floating point number +can be characterized in terms of the following parameters: -`complex float csinf (complex float Z)' - `complex.h' (ISO): *Note Trig Functions::. + * The "sign" is either `-1' or `1'. -`complex double csinh (complex double Z)' - `complex.h' (ISO): *Note Hyperbolic Functions::. + * The "base" or "radix" for exponentiation, an integer greater than + `1'. This is a constant for a particular representation. -`complex float csinhf (complex float Z)' - `complex.h' (ISO): *Note Hyperbolic Functions::. + * The "exponent" to which the base is raised. The upper and lower + bounds of the exponent value are constants for a particular + representation. -`complex long double csinhl (complex long double Z)' - `complex.h' (ISO): *Note Hyperbolic Functions::. + Sometimes, in the actual bits representing the floating point + number, the exponent is "biased" by adding a constant to it, to + make it always be represented as an unsigned quantity. This is + only important if you have some reason to pick apart the bit + fields making up the floating point number by hand, which is + something for which the GNU library provides no support. So this + is ignored in the discussion that follows. -`complex long double csinl (complex long double Z)' - `complex.h' (ISO): *Note Trig Functions::. + * The "mantissa" or "significand" is an unsigned integer which is a + part of each floating point number. -`tcflag_t CSIZE' - `termios.h' (POSIX.1): *Note Control Modes::. + * The "precision" of the mantissa. If the base of the representation + is B, then the precision is the number of base-B digits in the + mantissa. This is a constant for a particular representation. -`_CS_LFS64_CFLAGS' - `unistd.h' (Unix98): *Note String Parameters::. + Many floating point representations have an implicit "hidden bit" + in the mantissa. This is a bit which is present virtually in the + mantissa, but not stored in memory because its value is always 1 + in a normalized number. The precision figure (see above) includes + any hidden bits. -`_CS_LFS64_LDFLAGS' - `unistd.h' (Unix98): *Note String Parameters::. + Again, the GNU library provides no facilities for dealing with such + low-level aspects of the representation. -`_CS_LFS64_LIBS' - `unistd.h' (Unix98): *Note String Parameters::. + The mantissa of a floating point number represents an implicit +fraction whose denominator is the base raised to the power of the +precision. Since the largest representable mantissa is one less than +this denominator, the value of the fraction is always strictly less +than `1'. The mathematical value of a floating point number is then +the product of this fraction, the sign, and the base raised to the +exponent. -`_CS_LFS64_LINTFLAGS' - `unistd.h' (Unix98): *Note String Parameters::. + We say that the floating point number is "normalized" if the +fraction is at least `1/B', where B is the base. In other words, the +mantissa would be too large to fit if it were multiplied by the base. +Non-normalized numbers are sometimes called "denormal"; they contain +less precision than the representation normally can hold. -`_CS_LFS_CFLAGS' - `unistd.h' (Unix98): *Note String Parameters::. + If the number is not normalized, then you can subtract `1' from the +exponent while multiplying the mantissa by the base, and get another +floating point number with the same value. "Normalization" consists of +doing this repeatedly until the number is normalized. Two distinct +normalized floating point numbers cannot be equal in value. -`_CS_LFS_LDFLAGS' - `unistd.h' (Unix98): *Note String Parameters::. + (There is an exception to this rule: if the mantissa is zero, it is +considered normalized. Another exception happens on certain machines +where the exponent is as small as the representation can hold. Then it +is impossible to subtract `1' from the exponent, so a number may be +normalized even if its fraction is less than `1/B'.) -`_CS_LFS_LIBS' - `unistd.h' (Unix98): *Note String Parameters::. + +File: libc.info, Node: Floating Point Parameters, Next: IEEE Floating Point, Prev: Floating Point Concepts, Up: Floating Type Macros -`_CS_LFS_LINTFLAGS' - `unistd.h' (Unix98): *Note String Parameters::. +Floating Point Parameters +......................... -`_CS_PATH' - `unistd.h' (POSIX.2): *Note String Parameters::. + These macro definitions can be accessed by including the header file +`float.h' in your program. -`complex double csqrt (complex double Z)' - `complex.h' (ISO): *Note Exponents and Logarithms::. + Macro names starting with `FLT_' refer to the `float' type, while +names beginning with `DBL_' refer to the `double' type and names +beginning with `LDBL_' refer to the `long double' type.

Then you give `configure' the `--enable-add-ons' option to -activate them, and they will be compiled into the library.

The `--enable-add-ons' option tells configure to use all -the add-on bundles it finds in the source directory. Since important -functionality is provided in add-ons, you should always specify this -option. +`long double acosl (long double X)' + `math.h' (ISO): *Note Inverse Trig Functions::. - It may also be useful to set the CC and CFLAGS variables in the -environment when running `configure'.

If you specify both - options and BUILD-SYSTEM is different from HOST-SYSTEM, `configure' - will prepare to cross-compile glibc from BUILD-SYSTEM to be used - on HOST-SYSTEM. You'll probably need the `--with-headers' option - too, and you may have to override CONFIGURE's selection of the - compiler and/or binutils. +`void aio_init (const struct aioinit *INIT)' + `aio.h' (GNU): *Note Configuration of AIO::. - If you only specify `--host', configure will prepare for a native - compile but use what you specify instead of guessing what your - system is. This is most useful to change the CPU submodel. For - example, if configure guesses your machine as `i586-pc-linux-gnu' - but you want to compile a library for 386es, give - `--host=i386-pc-linux-gnu' or just `--host=i386-linux' and add the - appropriate compiler flags (`-mcpu=i386' will do the trick) to - CFLAGS. +`int aio_read (struct aiocb *AIOCBP)' + `aio.h' (POSIX.1b): *Note Asynchronous Reads/Writes::. - If you specify just `--build', configure will get confused. +`int aio_read64 (struct aiocb *AIOCBP)' + `aio.h' (Unix98): *Note Asynchronous Reads/Writes::. - To build the library and related programs, type `make'. This will -produce a lot of output, some of which may look like errors from `make' -but isn't. Look for error messages from `make' containing `***'. -Those indicate that something is really wrong. +`ssize_t aio_return (const struct aiocb *AIOCBP)' + `aio.h' (POSIX.1b): *Note Status of AIO Operations::. - The compilation process takes several hours even on fast hardware. -Expect at least two hours for the default configuration on i586 for -Linux. For Hurd times are much longer. Except for EGCS 1.1 and GCC -2.95 (and later versions of GCC), all supported versions of GCC have a -problem which causes them to take several minutes to compile certain -files in the iconvdata directory. Do not panic if the compiler appears -to hang. +`int aio_return64 (const struct aiocb64 *AIOCBP)' + `aio.h' (Unix98): *Note Status of AIO Operations::. - If you want to run a parallel make, you can't just give `make' the -`-j' option, because it won't be passed down to the sub-makes. -Instead, edit the generated `Makefile' and uncomment the line +`int aio_suspend (const struct aiocb *const LIST[], int NENT, const struct timespec *TIMEOUT)' + `aio.h' (POSIX.1b): *Note Synchronizing AIO Operations::. - # PARALLELMFLAGS = -j 4 +`int aio_suspend64 (const struct aiocb64 *const LIST[], int NENT, const struct timespec *TIMEOUT)' + `aio.h' (Unix98): *Note Synchronizing AIO Operations::. -You can change the `4' to some other number as appropriate for your -system. Instead of changing the `Makefile', you could give this option -directly to `make' and call it as, for example, `make -PARALLELMFLAGS=-j4'. If you're building in the source directory, you -must use the latter approach since in this case no new `Makefile' is -generated for you to change. +`int aio_write (struct aiocb *AIOCBP)' + `aio.h' (POSIX.1b): *Note Asynchronous Reads/Writes::. - To build and run test programs which exercise some of the library -facilities, type `make check'. If it does not complete successfully, -do not use the built library, and report a bug after verifying that the -problem is not already known. *Note Reporting Bugs::, for instructions -on reporting bugs. Note that some of the tests assume they are not -being run by `root'. We recommend you compile and test glibc as an -unprivileged user. +`int aio_write64 (struct aiocb *AIOCBP)' + `aio.h' (Unix98): *Note Asynchronous Reads/Writes::. - To format the `GNU C Library Reference Manual' for printing, type -`make dvi'. You need a working TeX installation to do this. The -distribution already includes the on-line formatted version of the -manual, as Info files. You can regenerate those with `make info', but -it shouldn't be necessary. +`unsigned int alarm (unsigned int SECONDS)' + `unistd.h' (POSIX.1): *Note Setting an Alarm::. - The library has a number of special-purpose configuration parameters -which you can find in `Makeconfig'. These can be overwritten with the -file `configparms'. To change them, create a `configparms' in your -build directory and add values as appropriate for your system. The -file is included and parsed by `make' and has to follow the conventions -for makefiles. +`void * alloca (size_t SIZE);' + `stdlib.h' (GNU, BSD): *Note Variable Size Automatic::. - It is easy to configure the GNU C library for cross-compilation by -setting a few variables in `configparms'. Set `CC' to the -cross-compiler for the target you configured the library for; it is -important to use this same `CC' value when running `configure', like -this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler -to use for for programs run on the build system as part of compiling -the library. You may need to set `AR' and `RANLIB' to cross-compiling -versions of `ar' and `ranlib' if the native tools are not configured to -work with object files for the target you configured for. +`int alphasort (const void *A, const void *B)' + `dirent.h' (BSD/SVID): *Note Scanning Directory Content::. - -File: libc.info, Node: Running make install, Next: Tools for Compilation, Prev: Configuring and compiling, Up: Installation +`int alphasort64 (const void *A, const void *B)' + `dirent.h' (GNU): *Note Scanning Directory Content::. -Installing the C Library -======================== +`tcflag_t ALTWERASE' + `termios.h' (BSD): *Note Local Modes::. - To install the library and its header files, and the Info files of -the manual, type `env LANGUAGE=C LC_ALL=C make install'. This will -build things if necessary, before installing them. However, you should -still compile everything first. If you are installing glibc as your -primary C library, we recommend that you shut the system down to -single-user mode first, and reboot afterward. This minimizes the risk -of breaking things when the library changes out from underneath. +`int ARG_MAX' + `limits.h' (POSIX.1): *Note General Limits::. - If you're upgrading from Linux libc5 or some other C library, you -need to replace the `/usr/include' with a fresh directory before -installing it. The new `/usr/include' should contain the Linux -headers, but nothing else. +`error_t argp_err_exit_status' + `argp.h' (GNU): *Note Argp Global Variables::. - You must first build the library (`make'), optionally check it -(`make check'), switch the include directories and then install (`make -install'). The steps must be done in this order. Not moving the -directory before install will result in an unusable mixture of header -files from both libraries, but configuring, building, and checking the -library requires the ability to compile and run programs against the old -library. +`void argp_error (const struct argp_state *STATE, const char *FMT, ...)' + `argp.h' (GNU): *Note Argp Helper Functions::. - If you are upgrading from a previous installation of glibc 2.0 or -2.1, `make install' will do the entire job. You do not need to remove -the old includes - if you want to do so anyway you must then follow the -order given above. +`int ARGP_ERR_UNKNOWN' + `argp.h' (GNU): *Note Argp Parser Functions::. - You may also need to reconfigure GCC to work with the new library. -The easiest way to do that is to figure out the compiler switches to -make it work again (`-Wl,--dynamic-linker=/lib/ld-linux.so.2' should -work on Linux systems) and use them to recompile gcc. You can also -edit the specs file (`/usr/lib/gcc-lib/TARGET/VERSION/specs'), but that -is a bit of a black art. +`void argp_failure (const struct argp_state *STATE, int STATUS, int ERRNUM, const char *FMT, ...)' + `argp.h' (GNU): *Note Argp Helper Functions::. - You can install glibc somewhere other than where you configured it -to go by setting the `install_root' variable on the command line for -`make install'. The value of this variable is prepended to all the -paths for installation. This is useful when setting up a chroot -environment or preparing a binary distribution. The directory should be -specified with an absolute file name. +`void argp_help (const struct argp *ARGP, FILE *STREAM, unsigned FLAGS, char *NAME)' + `argp.h' (GNU): *Note Argp Help::. - Glibc 2.2 includes a daemon called `nscd', which you may or may not -want to run. `nscd' caches name service lookups; it can dramatically -improve performance with NIS+, and may help with DNS as well. +`ARGP_IN_ORDER' + `argp.h' (GNU): *Note Argp Flags::. - One auxiliary program, `/usr/libexec/pt_chown', is installed setuid -`root'. This program is invoked by the `grantpt' function; it sets the -permissions on a pseudoterminal so it can be used by the calling -process. This means programs like `xterm' and `screen' do not have to -be setuid to get a pty. (There may be other reasons why they need -privileges.) If you are using a 2.1 or newer Linux kernel with the -`devptsfs' or `devfs' filesystems providing pty slaves, you don't need -this program; otherwise you do. The source for `pt_chown' is in -`login/programs/pt_chown.c'. +`ARGP_KEY_ARG' + `argp.h' (GNU): *Note Argp Special Keys::. - After installation you might want to configure the timezone and -locale installation of your system. The GNU C library comes with a -locale database which gets configured with `localedef'. For example, to -set up a German locale with name `de_DE', simply issue the command -`localedef -i de_DE -f ISO-8859-1 de_DE'. To configure all locales -that are supported by glibc, you can issue from your build directory the -command `make localedata/install-locales'. +`ARGP_KEY_ARGS' + `argp.h' (GNU): *Note Argp Special Keys::. - To configure the locally used timezone, you can either set the `TZ' -environment variable.

A configuration -specifies an ordered list of these subdirectories. Each subdirectory -implicitly appends its parent directory to the list. For example, -specifying the list `unix/bsd/vax' is equivalent to specifying the list -`unix/bsd/vax unix/bsd unix'.

First, the makefiles do not bother to -look for a system-dependent version of a file that's not in `generic'. -This means that any system-dependent source file must have an analogue -in `generic', even if the routines defined by that file are not -implemented on other platforms.

The script can check for - `--with-PACKAGE' options that were passed to the top-level - `configure'. For an option `--with-PACKAGE=VALUE' `configure' - sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE - converted to underscores) to VALUE; if the option is just - `--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to - `yes'. +`char * bind_textdomain_codeset (const char *DOMAINNAME, const char *CODESET)' + `libintl.h' (GNU): *Note Charset conversion in gettext::. -`configure.in' - This file is an Autoconf input fragment to be processed into the - file `configure' in this subdirectory. *Note Introduction: - (autoconf.info)Introduction, for a description of Autoconf.

If the -`--nfp' option is _not_ passed to `configure', the directory -`MACHINE/fpu' is also used. The operating system often has a "base -operating system"; for example, if the operating system is `Linux', the -base operating system is `unix/sysv'. The algorithm used to pick the -list of directories is simple: `configure' makes a list of the base -operating system, manufacturer, CPU type, and operating system, in that -order. It then concatenates all these together with slashes in -between, to produce a directory name; for example, the configuration -`i686-linux-gnu' results in `unix/sysv/linux/i386/i686'. `configure' -then tries removing each element of the list in turn, so -`unix/sysv/linux' and `unix/sysv' are also tried, among others. Since -the precise version number of the operating system is often not -important, and it would be very inconvenient, for example, to have -identical `irix6.2' and `irix6.3' directories, `configure' tries -successively less specific operating system names by removing trailing -suffixes starting with a period. +`_BSD_SOURCE' + (GNU): *Note Feature Test Macros::. - As an example, here is the complete list of directories that would be -tried for the configuration `i686-linux-gnu' (with the `crypt' and -`linuxthreads' add-on): +`void * bsearch (const void *KEY, const void *ARRAY, size_t COUNT, size_t SIZE, comparison_fn_t COMPARE)' + `stdlib.h' (ISO): *Note Array Search Function::. - sysdeps/i386/elf - crypt/sysdeps/unix - linuxthreads/sysdeps/unix/sysv/linux - linuxthreads/sysdeps/pthread - linuxthreads/sysdeps/unix/sysv - linuxthreads/sysdeps/unix - linuxthreads/sysdeps/i386/i686 - linuxthreads/sysdeps/i386 - linuxthreads/sysdeps/pthread/no-cmpxchg - sysdeps/unix/sysv/linux/i386 - sysdeps/unix/sysv/linux - sysdeps/gnu - sysdeps/unix/common - sysdeps/unix/mman - sysdeps/unix/inet - sysdeps/unix/sysv/i386/i686 - sysdeps/unix/sysv/i386 - sysdeps/unix/sysv - sysdeps/unix/i386 - sysdeps/unix - sysdeps/posix - sysdeps/i386/i686 - sysdeps/i386/i486 - sysdeps/libm-i387/i686 - sysdeps/i386/fpu - sysdeps/libm-i387 - sysdeps/i386 - sysdeps/wordsize-32 - sysdeps/ieee754 - sysdeps/libm-ieee754 - sysdeps/generic +`wint_t btowc (int C)' + `wchar.h' (ISO): *Note Converting a Character::. - Different machine architectures are conventionally subdirectories at -the top level of the `sysdeps' directory tree.

Some parts of the library were -contributed or worked on by other people. + Before you do anything else, you should read the file `FAQ' found at +the top level of the source tree. This file answers common questions +and describes problems you may experience with compilation and +installation. It is updated more frequently than this manual. - * The `getopt' function and related code was written by Richard - Stallman, David J. MacKenzie, and Roland McGrath. + Features can be added to GNU Libc via "add-on" bundles. These are +separate tarfiles which you unpack into the top level of the source +tree. Then you give `configure' the `--enable-add-ons' option to +activate them, and they will be compiled into the library. As of the +2.2 release, one important component of glibc is distributed as +"official" add-ons: the linuxthreads add-on. Unless you are doing an +unusual installation, you should get this. - * The merge sort function `qsort' was written by Michael J. Haertel. + Support for POSIX threads is maintained by someone else, so it's in a +separate package. It is only available for Linux systems, but this will +change in the future. Get it from the same place you got the main +bundle; the file is `glibc-linuxthreads-VERSION.tar.gz'. - * The quick sort function used as a fallback by `qsort' was written - by Douglas C. Schmidt. + You will need recent versions of several GNU tools: definitely GCC +and GNU Make, and possibly others. *Note Tools for Compilation::, +below. - * The memory allocation functions `malloc', `realloc' and `free' and - related code were written by Michael J. Haertel, Wolfram Gloger, - and Doug Lea. +* Menu: - * Fast implementations of many of the string functions (`memcpy', - `strlen', etc.) were written by Torbjo"rn Granlund. +* Configuring and compiling:: How to compile and test GNU libc. +* Running make install:: How to install it once you've got it compiled. +* Tools for Compilation:: You'll need these first. +* Supported Configurations:: What it runs on, what it doesn't. +* Linux:: Specific advice for Linux systems. +* Reporting Bugs:: So they'll get fixed. - * The `tar.h' header file was written by David J. MacKenzie. + +File: libc.info, Node: Configuring and compiling, Next: Running make install, Up: Installation - * The port to the MIPS DECStation running Ultrix 4 - (`mips-dec-ultrix4') was contributed by Brendan Kehoe and Ian - Lance Taylor. +Configuring and compiling GNU Libc +================================== - * The DES encryption function `crypt' and related functions were - contributed by Michael Glad. + GNU libc can be compiled in the source directory, but we strongly +advise to build it in a separate build directory. For example, if you +have unpacked the glibc sources in `/src/gnu/glibc-2.2.0', create a +directory `/src/gnu/glibc-build' to put the object files in. This +allows removing the whole build directory in case an error occurs, +which is the safest way to get a fresh start and should always be done. - * The `ftw' and `nftw' functions were contributed by Ulrich Drepper. + From your object directory, run the shell script `configure' found +at the top level of the source tree. In the scenario above, you'd type - * The startup code to support SunOS shared libraries was contributed - by Tom Quinn. + $ ../glibc-2.2.0/configure ARGS... - * The `mktime' function was contributed by Paul Eggert. + Please note that even if you're building in a separate build +directory, the compilation needs to modify a few files in the source +directory, especially some files in the manual subdirectory. - * The port to the Sequent Symmetry running Dynix version 3 - (`i386-sequent-bsd') was contributed by Jason Merrill. +`configure' takes many options, but you can get away with knowing only +two: `--prefix' and `--enable-add-ons'. The `--prefix' option tells +configure where you want glibc installed. This defaults to +`/usr/local'. The `--enable-add-ons' option tells configure to use all +the add-on bundles it finds in the source directory. Since important +functionality is provided in add-ons, you should always specify this +option. - * The timezone support code is derived from the public-domain - timezone package by Arthur David Olson and his many contributors. + It may also be useful to set the CC and CFLAGS variables in the +environment when running `configure'. CC selects the C compiler that +will be used, and CFLAGS sets optimization options for the compiler. - * The port to the DEC Alpha running OSF/1 (`alpha-dec-osf1') was - contributed by Brendan Kehoe, using some code written by Roland - McGrath. + The following list describes all of the available options for +`configure': - * The port to SGI machines running Irix 4 (`mips-sgi-irix4') was - contributed by Tom Quinn. +`--prefix=DIRECTORY' + Install machine-independent data files in subdirectories of + `DIRECTORY'. The default is to install in `/usr/local'. - * The port of the Mach and Hurd code to the MIPS architecture - (`mips-ANYTHING-gnu') was contributed by Kazumoto Kojima. +`--exec-prefix=DIRECTORY' + Install the library and other machine-dependent files in + subdirectories of `DIRECTORY'. The default is to the `--prefix' + directory if that option is specified, or `/usr/local' otherwise. - * The floating-point printing function used by `printf' and friends - and the floating-point reading function used by `scanf', `strtod' - and friends were written by Ulrich Drepper. The multi-precision - integer functions used in those functions are taken from GNU MP, - which was contributed by Torbjo"rn Granlund. +`--with-headers=DIRECTORY' + Look for kernel header files in DIRECTORY, not `/usr/include'. + Glibc needs information from the kernel's private header files. + It will normally look in `/usr/include' for them, but if you + specify this option, it will look in DIRECTORY instead. - * The internationalization support in the library, and the support - programs `locale' and `localedef', were written by Ulrich Drepper. - Ulrich Drepper adapted the support code for message catalogs - (`libintl.h', etc.) from the GNU `gettext' package, which he also - wrote. He also contributed the `catgets' support and the entire - suite of multi-byte and wide-character support functions - (`wctype.h', `wchar.h', etc.). + This option is primarily of use on a system where the headers in + `/usr/include' come from an older version of glibc. Conflicts can + occasionally happen in this case. Note that Linux libc5 qualifies + as an older version of glibc. You can also use this option if you + want to compile glibc with a newer set of kernel headers than the + ones found in `/usr/include'. - * The implementations of the `nsswitch.conf' mechanism and the files - and DNS backends for it were designed and written by Ulrich - Drepper and Roland McGrath, based on a backend interface defined - by Peter Eriksson. +`--enable-add-ons[=LIST]' + Enable add-on packages in your source tree. If this option is + specified with no list, it enables all the add-on packages it + finds. If you do not wish to use some add-on package that you + have present in your source tree, give this option a list of the + add-ons that you _do_ want used, like this: + `--enable-add-ons=linuxthreads' - * The port to Linux i386/ELF (`i386-ANYTHING-linux') was contributed - by Ulrich Drepper, based in large part on work done in Hongjiu - Lu's Linux version of the GNU C Library. +`--enable-kernel=VERSION' + This option is currently only useful on Linux systems. The + VERSION parameter should have the form X.Y.Z and describes the + smallest version of the Linux kernel the generated library is + expected to support. The higher the VERSION number is, the less + compatibility code is added, and the faster the code gets. - * The port to Linux/m68k (`m68k-ANYTHING-linux') was contributed by - Andreas Schwab. +`--with-binutils=DIRECTORY' + Use the binutils (assembler and linker) in `DIRECTORY', not the + ones the C compiler would default to. You could use this option if + the default binutils on your system cannot deal with all the + constructs in the GNU C library. In that case, `configure' will + detect the problem and suppress these constructs, so that the + library will still be usable, but functionality may be lost--for + example, you can't build a shared libc with old binutils. - * The ports to Linux/ARM (`arm-ANYTHING-linuxaout') and ARM - standalone (`arm-ANYTHING-none'), as well as parts of the IPv6 - support code, were contributed by Philip Blundell. +`--without-fp' + Use this option if your computer lacks hardware floating-point + support and your operating system does not emulate an FPU. - * Richard Henderson contributed the ELF dynamic linking code and - other support for the Alpha processor. +`--disable-shared' + Don't build shared libraries even if it is possible. Not all + systems support shared libraries; you need ELF support and + (currently) the GNU linker. - * David Mosberger-Tang contributed the port to Linux/Alpha - (`alpha-ANYTHING-linux'). +`--disable-profile' + Don't build libraries with profiling information. You may want to + use this option if you don't plan to do profiling. - * The port to Linux on PowerPC (`powerpc-ANYTHING-linux') was - contributed by Geoffrey Keating. +`--enable-omitfp' + Use maximum optimization for the normal (static and shared) + libraries, and compile separate static libraries with debugging + information and no optimization. We recommend against this. The + extra optimization doesn't gain you much, it may provoke compiler + bugs, and you won't be able to trace bugs through the C library. - * Miles Bader wrote the argp argument-parsing package, and the - argz/envz interfaces. +`--disable-versioning' + Don't compile the shared libraries with symbol version information. + Doing this will make the resulting library incompatible with old + binaries, so it's not recommended. - * Stephen R. van den Berg contributed a highly-optimized `strstr' - function. +`--enable-static-nss' + Compile static versions of the NSS (Name Service Switch) libraries. + This is not recommended because it defeats the purpose of NSS; a + program linked statically with the NSS libraries cannot be + dynamically reconfigured to use a different name database. - * Ulrich Drepper contributed the `hsearch' and `drand48' families of - functions; reentrant `...`_r'' versions of the `random' family; - System V shared memory and IPC support code; and several - highly-optimized string functions for iX86 processors. +`--build=BUILD-SYSTEM' +`--host=HOST-SYSTEM' + These options are for cross-compiling. If you specify both + options and BUILD-SYSTEM is different from HOST-SYSTEM, `configure' + will prepare to cross-compile glibc from BUILD-SYSTEM to be used + on HOST-SYSTEM. You'll probably need the `--with-headers' option + too, and you may have to override CONFIGURE's selection of the + compiler and/or binutils. - * The math functions are taken from `fdlibm-5.1' by Sun - Microsystems, as modified by J.T. Conklin, Ian Lance Taylor, - Ulrich Drepper, Andreas Schwab, and Roland McGrath. + If you only specify `--host', configure will prepare for a native + compile but use what you specify instead of guessing what your + system is. This is most useful to change the CPU submodel. For + example, if configure guesses your machine as `i586-pc-linux-gnu' + but you want to compile a library for 386es, give + `--host=i386-pc-linux-gnu' or just `--host=i386-linux' and add the + appropriate compiler flags (`-mcpu=i386' will do the trick) to + CFLAGS. - * The `libio' library used to implement `stdio' functions on some - platforms was written by Per Bothner and modified by Ulrich - Drepper. + If you specify just `--build', configure will get confused. - * Eric Youngdale and Ulrich Drepper implemented versioning of - objects on symbol level. + To build the library and related programs, type `make'. This will +produce a lot of output, some of which may look like errors from `make' +but isn't. Look for error messages from `make' containing `***'. +Those indicate that something is really wrong. - * Thorsten Kukuk provided an implementation for NIS (YP) and NIS+, - securelevel 0, 1 and 2. + The compilation process takes several hours even on fast hardware. +Expect at least two hours for the default configuration on i586 for +Linux. For Hurd times are much longer. Except for EGCS 1.1 and GCC +2.95 (and later versions of GCC), all supported versions of GCC have a +problem which causes them to take several minutes to compile certain +files in the iconvdata directory. Do not panic if the compiler appears +to hang. - * Andreas Jaeger provided a test suite for the math library. + If you want to run a parallel make, you can't just give `make' the +`-j' option, because it won't be passed down to the sub-makes. +Instead, edit the generated `Makefile' and uncomment the line - * Mark Kettenis implemented the utmpx interface and an utmp daemon. + # PARALLELMFLAGS = -j 4 - * Ulrich Drepper added character conversion functions (`iconv'). +You can change the `4' to some other number as appropriate for your +system. Instead of changing the `Makefile', you could give this option +directly to `make' and call it as, for example, `make +PARALLELMFLAGS=-j4'. If you're building in the source directory, you +must use the latter approach since in this case no new `Makefile' is +generated for you to change. - * Thorsten Kukuk provided an implementation for a caching daemon for - NSS (nscd). + To build and run test programs which exercise some of the library +facilities, type `make check'. If it does not complete successfully, +do not use the built library, and report a bug after verifying that the +problem is not already known. *Note Reporting Bugs::, for instructions +on reporting bugs. Note that some of the tests assume they are not +being run by `root'. We recommend you compile and test glibc as an +unprivileged user. - * Tim Waugh provided an implementation of the POSIX.2 wordexp - function family. + To format the `GNU C Library Reference Manual' for printing, type +`make dvi'. You need a working TeX installation to do this. The +distribution already includes the on-line formatted version of the +manual, as Info files. You can regenerate those with `make info', but +it shouldn't be necessary. - * Mark Kettenis provided a Hesiod NSS module. + The library has a number of special-purpose configuration parameters +which you can find in `Makeconfig'. These can be overwritten with the +file `configparms'. To change them, create a `configparms' in your +build directory and add values as appropriate for your system. The +file is included and parsed by `make' and has to follow the conventions +for makefiles. - * The Internet-related code (most of the `inet' subdirectory) and - several other miscellaneous functions and header files have been - included from 4.4 BSD with little or no modification. + It is easy to configure the GNU C library for cross-compilation by +setting a few variables in `configparms'. Set `CC' to the +cross-compiler for the target you configured the library for; it is +important to use this same `CC' value when running `configure', like +this: `CC=TARGET-gcc configure TARGET'. Set `BUILD_CC' to the compiler +to use for for programs run on the build system as part of compiling +the library. You may need to set `AR' and `RANLIB' to cross-compiling +versions of `ar' and `ranlib' if the native tools are not configured to +work with object files for the target you configured for. - All code incorporated from 4.4 BSD is under the following - copyright: + +File: libc.info, Node: Running make install, Next: Tools for Compilation, Prev: Configuring and compiling, Up: Installation - Copyright (C) 1991 Regents of the University of California. - All rights reserved. +Installing the C Library +======================== - Redistribution and use in source and binary forms, with or - without modification, are permitted provided that the - following conditions are met: + To install the library and its header files, and the Info files of +the manual, type `env LANGUAGE=C LC_ALL=C make install'.

This minimizes the risk +of breaking things when the library changes out from underneath. - 1. Redistributions of source code must retain the above - copyright notice, this list of conditions and the - following disclaimer. + If you're upgrading from Linux libc5 or some other C library, you +need to replace the `/usr/include' with a fresh directory before +installing it. The new `/usr/include' should contain the Linux +headers, but nothing else. - 2. Redistributions in binary form must reproduce the above - copyright notice, this list of conditions and the - following disclaimer in the documentation and/or other - materials provided with the distribution. + You must first build the library (`make'), optionally check it +(`make check'), switch the include directories and then install (`make +install'). The steps must be done in this order. Not moving the +directory before install will result in an unusable mixture of header +files from both libraries, but configuring, building, and checking the +library requires the ability to compile and run programs against the old +library. - 3. [This condition was removed.] + If you are upgrading from a previous installation of glibc 2.0 or +2.1, `make install' will do the entire job.

They have undergone minor - changes to fit into the GNU C library and to fit the ISO C - standard, but the functional code is Berkeley's. + Glibc 2.2 includes a daemon called `nscd', which you may or may not +want to run. `nscd' caches name service lookups; it can dramatically +improve performance with NIS+, and may help with DNS as well. - * The DNS resolver code is taken directly from BIND 4.9.5, which is - under both the Berkeley copyright above and also: + One auxiliary program, `/usr/libexec/pt_chown', is installed setuid +`root'. This program is invoked by the `grantpt' function; it sets the +permissions on a pseudoterminal so it can be used by the calling +process. This means programs like `xterm' and `screen' do not have to +be setuid to get a pty. (There may be other reasons why they need +privileges.)

The source for `pt_chown' is in +`login/programs/pt_chown.c'. - Portions Copyright (C) 1993 by Digital Equipment Corporation. + After installation you might want to configure the timezone and +locale installation of your system. The GNU C library comes with a +locale database which gets configured with `localedef'. For example, to +set up a German locale with name `de_DE', simply issue the command +`localedef -i de_DE -f ISO-8859-1 de_DE'.

It also counts - as the successor of the GNU Library Public License, version 2, hence the - version number 2.1.] + If you are installing GNU libc on a Linux system, you need to have +the header files from a 2.2 or newer kernel around for reference. For +some architectures, like ia64, sh and hppa, you need at least headers +from kernel 2.3.99 (sh and hppa) or 2.4.0 (ia64). You do not need to +use that kernel, just have its headers where glibc can access at them. +The easiest way to do this is to unpack it in a directory such as +`/usr/src/linux-2.2.1'. In that directory, run `make config' and +accept all the defaults. Then run `make include/linux/version.h'. +Finally, configure glibc with the option +`--with-headers=/usr/src/linux-2.2.1/include'. Use the most recent +kernel you can get your hands on. -Preamble --------- + An alternate tactic is to unpack the 2.2 kernel and run `make +config' as above. Then rename or delete `/usr/include', create a new +`/usr/include', and make the usual symbolic links of +`/usr/include/linux' and `/usr/include/asm' into the 2.2 kernel +sources. You can then configure glibc with no special options. This +tactic is recommended if you are upgrading from libc5, since you need +to get rid of the old header files anyway. - The licenses for most software are designed to take away your -freedom to share and change it. By contrast, the GNU General Public -Licenses are intended to guarantee your freedom to share and change -free software--to make sure the software is free for all its users. + Note that `/usr/include/net' and `/usr/include/scsi' should *not* be +symlinks into the kernel sources. GNU libc provides its own versions +of these files. - This license, the Lesser General Public License, applies to some -specially designated software--typically libraries--of the Free -Software Foundation and other authors who decide to use it. You can use -it too, but we suggest you first think carefully about whether this -license or the ordinary General Public License is the better strategy to -use in any particular case, based on the explanations below. + Linux expects some components of the libc installation to be in +`/lib' and some in `/usr/lib'. This is handled automatically if you +configure glibc with `--prefix=/usr'. If you set some other prefix or +allow it to default to `/usr/local', then all the components are +installed there. - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of it -in new free programs; and that you are informed that you can do these -things. + If you are upgrading from libc5, you need to recompile every shared +library on your system against the new library for the sake of new code, +but keep the old libraries around for old binaries to use. This is +complicated and difficult. Consult the Glibc2 HOWTO at + for details. - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. + You cannot use `nscd' with 2.0 kernels, due to bugs in the +kernel-side thread support. `nscd' happens to hit these bugs +particularly hard, but you might have problems with any threaded +program. - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. + +File: libc.info, Node: Reporting Bugs, Prev: Linux, Up: Installation - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. +Reporting Bugs +============== - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know that -what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. + There are probably bugs in the GNU C library. There are certainly +errors and omissions in this manual. If you report them, they will get +fixed. If you don't, no one will ever know about them and they will +remain unfixed for all eternity, if not longer. - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. + It is a good idea to verify that the problem has not already been +reported. Bugs are documented in two places: The file `BUGS' describes +a number of well known bugs and the bug tracking system has a WWW +interface at . The +WWW interface gives you access to open and closed reports. The closed +reports normally include a patch or a hint on solving the problem. - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and is -quite different from the ordinary General Public License. We use this -license for certain libraries in order to permit linking those -libraries into non-free programs. + To report a bug, first you must find it. Hopefully, this will be the +hard part. Once you've found a bug, make sure it's really a bug. A +good way to do this is to see if the GNU C library behaves the same way +some other C library does. If so, probably you are wrong and the +libraries are right (but not necessarily). If not, one of the libraries +is probably wrong. It might not be the GNU library. Many historical +Unix C libraries permit things that we don't, such as closing a file +twice. - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. + If you think you have found some way in which the GNU C library does +not conform to the ISO and POSIX standards (*note Standards and +Portability::), that is definitely a bug. Report it! - We call this license the "Lesser" General Public License because it -does _Less_ to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. + Once you're sure you've found a bug, try to narrow it down to the +smallest test case that reproduces the problem. In the case of a C +library, you really only need to narrow it down to one library function +call, if possible. This should not be too difficult. - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it -becomes a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. + The final step when you have a simple test case is to report the bug. +Do this using the `glibcbug' script. It is installed with libc, or if +you haven't installed it, will be in your build directory. Send your +test case, the results you got, the results you expected, and what you +think the problem might be (if you've thought of anything). `glibcbug' +will insert the configuration information we need to see, and ship the +report off to . Don't send a message there directly; it +is fed to a program that expects mail to be formatted in a particular +way. Use the script. - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of free -software. For example, permission to use the GNU C Library in non-free -programs enables many more people to use the whole GNU operating -system, as well as its variant, the GNU/Linux operating system. + If you are not sure how a function should behave, and this manual +doesn't tell you, that's a bug in the manual. Report that too! If the +function's behavior disagrees with the manual, then either the library +or the manual has a bug, so report the disagreement. If you find any +errors or omissions in this manual, please report them to the Internet +address . If you refer to specific sections +of the manual, please include the section names for easier +identification. - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run that -program using a modified version of the Library. + +File: libc.info, Node: Maintenance, Next: Contributors, Prev: Installation, Up: Top - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library".

This License Agreement applies to any software library or other - program which contains a notice placed by the copyright holder or - other authorized party saying it may be distributed under the - terms of this Lesser General Public License (also called "this - License").

A "work based on the - Library" means either the Library or any derivative work under - copyright law: that is to say, a work containing the Library or a - portion of it, either verbatim or with modifications and/or - translated straightforwardly into another language. (Hereinafter, - translation is included without limitation in the term - "modification".) + +File: libc.info, Node: Source Layout, Next: Porting, Up: Maintenance - "Source code" for a work means the preferred form of the work for - making modifications to it. For a library, complete source code - means all the source code for all modules it contains, plus any - associated interface definition files, plus the scripts used to - control compilation and installation of the library. +Adding New Functions +==================== - Activities other than copying, distribution and modification are - not covered by this License; they are outside its scope. The act - of running a program using the Library is not restricted, and - output from such a program is covered only if its contents - constitute a work based on the Library (independent of the use of - the Library in a tool for writing it). Whether that is true - depends on what the Library does and what the program that uses - the Library does. + The process of building the library is driven by the makefiles, which +make heavy use of special features of GNU `make'. The makefiles are +very complex, and you probably don't want to try to understand them. +But what they do is fairly straightforward, and only requires that you +define a few variables in the right places. - 1. You may copy and distribute verbatim copies of the Library's - complete source code as you receive it, in any medium, provided - that you conspicuously and appropriately publish on each copy an - appropriate copyright notice and disclaimer of warranty; keep - intact all the notices that refer to this License and to the - absence of any warranty; and distribute a copy of this License - along with the Library. + The library sources are divided into subdirectories, grouped by +topic. - You may charge a fee for the physical act of transferring a copy, - and you may at your option offer warranty protection in exchange - for a fee. + The `string' subdirectory has all the string-manipulation functions, +`math' has all the mathematical functions, etc. - 2. You may modify your copy or copies of the Library or any portion - of it, thus forming a work based on the Library, and copy and - distribute such modifications or work under the terms of Section 1 - above, provided that you also meet all of these conditions: + Each subdirectory contains a simple makefile, called `Makefile', +which defines a few `make' variables and then includes the global +makefile `Rules' with a line like: - a. The modified work must itself be a software library. + include ../Rules - b. You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. +The basic variables that a subdirectory makefile defines are: - c. You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. +`subdir' + The name of the subdirectory, for example `stdio'. This variable + *must* be defined. - d. If a facility in the modified Library refers to a function or - a table of data to be supplied by an application program that - uses the facility, other than as an argument passed when the - facility is invoked, then you must make a good faith effort - to ensure that, in the event an application does not supply - such function or table, the facility still operates, and - performs whatever part of its purpose remains meaningful. +`headers' + The names of the header files in this section of the library, such + as `stdio.h'. - (For example, a function in a library to compute square roots - has a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function - must be optional: if the application does not supply it, the - square root function must still compute square roots.) +`routines' +`aux' + The names of the modules (source files) in this section of the + library. These should be simple names, such as `strlen' (rather + than complete file names, such as `strlen.c'). Use `routines' for + modules that define functions in the library, and `aux' for + auxiliary modules containing things like data definitions. But the + values of `routines' and `aux' are just concatenated, so there + really is no practical difference. - These requirements apply to the modified work as a whole. If - identifiable sections of that work are not derived from the - Library, and can be reasonably considered independent and separate - works in themselves, then this License, and its terms, do not - apply to those sections when you distribute them as separate - works. But when you distribute the same sections as part of a - whole which is a work based on the Library, the distribution of - the whole must be on the terms of this License, whose permissions - for other licensees extend to the entire whole, and thus to each - and every part regardless of who wrote it. +`tests' + The names of test programs for this section of the library. These + should be simple names, such as `tester' (rather than complete file + names, such as `tester.c'). `make tests' will build and run all + the test programs. If a test program needs input, put the test + data in a file called `TEST-PROGRAM.input'; it will be given to + the test program on its standard input. If a test program wants + to be run with arguments, put the arguments (all on a single line) + in a file called `TEST-PROGRAM.args'. Test programs should exit + with zero status when the test passes, and nonzero status when the + test indicates a bug in the library or error in building. - Thus, it is not the intent of this section to claim rights or - contest your rights to work written entirely by you; rather, the - intent is to exercise the right to control the distribution of - derivative or collective works based on the Library. +`others' + The names of "other" programs associated with this section of the + library. These are programs which are not tests per se, but are + other small programs included with the library. They are built by + `make others'. - In addition, mere aggregation of another work not based on the - Library with the Library (or with a work based on the Library) on - a volume of a storage or distribution medium does not bring the - other work under the scope of this License. +`install-lib' +`install-data' +`install' + Files to be installed by `make install'. Files listed in + `install-lib' are installed in the directory specified by `libdir' + in `configparms' or `Makeconfig' (*note Installation::). Files + listed in `install-data' are installed in the directory specified + by `datadir' in `configparms' or `Makeconfig'. Files listed in + `install' are installed in the directory specified by `bindir' in + `configparms' or `Makeconfig'. - 3. You may opt to apply the terms of the ordinary GNU General Public - License instead of this License to a given copy of the Library. - To do this, you must alter all the notices that refer to this - License, so that they refer to the ordinary GNU General Public - License, version 2, instead of to this License. (If a newer - version than version 2 of the ordinary GNU General Public License - has appeared, then you can specify that version instead if you - wish.) Do not make any other change in these notices. +`distribute' + Other files from this subdirectory which should be put into a + distribution tar file. You need not list here the makefile itself + or the source and header files listed in the other standard + variables. Only define `distribute' if there are files used in an + unusual way that should go into the distribution. - Once this change is made in a given copy, it is irreversible for - that copy, so the ordinary GNU General Public License applies to - all subsequent copies and derivative works made from that copy. +`generated' + Files which are generated by `Makefile' in this subdirectory. + These files will be removed by `make clean', and they will never + go into a distribution. - This option is useful when you wish to copy part of the code of - the Library into a program that is not a library. +`extra-objs' + Extra object files which are built by `Makefile' in this + subdirectory. This should be a list of file names like `foo.o'; + the files will actually be found in whatever directory object + files are being built in. These files will be removed by + `make clean'. This variable is used for secondary object files + needed to build `others' or `tests'. - 4. You may copy and distribute the Library (or a portion or - derivative of it, under Section 2) in object code or executable - form under the terms of Sections 1 and 2 above provided that you - accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software - interchange. + +File: libc.info, Node: Porting, Prev: Source Layout, Up: Maintenance - If distribution of object code is made by offering access to copy - from a designated place, then offering equivalent access to copy - the source code from the same place satisfies the requirement to - distribute the source code, even though third parties are not - compelled to copy the source along with the object code. +Porting the GNU C Library +========================= - 5. A program that contains no derivative of any portion of the - Library, but is designed to work with the Library by being - compiled or linked with it, is called a "work that uses the - Library". Such a work, in isolation, is not a derivative work of - the Library, and therefore falls outside the scope of this License. + The GNU C library is written to be easily portable to a variety of +machines and operating systems. Machine- and operating system-dependent +functions are well separated to make it easy to add implementations for +new machines or operating systems. This section describes the layout of +the library source tree and explains the mechanisms used to select +machine-dependent code to use. - However, linking a "work that uses the Library" with the Library - creates an executable that is a derivative of the Library (because - it contains portions of the Library), rather than a "work that - uses the library". The executable is therefore covered by this - License. Section 6 states terms for distribution of such - executables. + All the machine-dependent and operating system-dependent files in the +library are in the subdirectory `sysdeps' under the top-level library +source directory. This directory contains a hierarchy of +subdirectories (*note Hierarchy Conventions::). - When a "work that uses the Library" uses material from a header - file that is part of the Library, the object code for the work may - be a derivative work of the Library even though the source code is - not. Whether this is true is especially significant if the work - can be linked without the Library, or if the work is itself a - library. The threshold for this to be true is not precisely - defined by law. + Each subdirectory of `sysdeps' contains source files for a +particular machine or operating system, or for a class of machine or +operating system (for example, systems by a particular vendor, or all +machines that use IEEE 754 floating-point format). A configuration +specifies an ordered list of these subdirectories. Each subdirectory +implicitly appends its parent directory to the list. For example, +specifying the list `unix/bsd/vax' is equivalent to specifying the list +`unix/bsd/vax unix/bsd unix'. A subdirectory can also specify that it +implies other subdirectories which are not directly above it in the +directory hierarchy. If the file `Implies' exists in a subdirectory, +it lists other subdirectories of `sysdeps' which are appended to the +list, appearing after the subdirectory containing the `Implies' file. +Lines in an `Implies' file that begin with a `#' character are ignored +as comments. For example, `unix/bsd/Implies' contains: + # BSD has Internet-related things. + unix/inet - If such an object file uses only numerical parameters, data - structure layouts and accessors, and small macros and small inline - functions (ten lines or less in length), then the use of the object - file is unrestricted, regardless of whether it is legally a - derivative work. (Executables containing this object code plus - portions of the Library will still fall under Section 6.) +and `unix/Implies' contains: + posix - Otherwise, if the work is a derivative of the Library, you may - distribute the object code for the work under the terms of Section - 6. Any executables containing that work also fall under Section 6, - whether or not they are linked directly with the Library itself. +So the final list is `unix/bsd/vax unix/bsd unix/inet unix posix'. - 6. As an exception to the Sections above, you may also combine or - link a "work that uses the Library" with the Library to produce a - work containing portions of the Library, and distribute that work - under terms of your choice, provided that the terms permit - modification of the work for the customer's own use and reverse - engineering for debugging such modifications. + `sysdeps' has a "special" subdirectory called `generic'. It is +always implicitly appended to the list of subdirectories, so you +needn't put it in an `Implies' file, and you should not create any +subdirectories under it intended to be new specific categories. +`generic' serves two purposes. First, the makefiles do not bother to +look for a system-dependent version of a file that's not in `generic'. +This means that any system-dependent source file must have an analogue +in `generic', even if the routines defined by that file are not +implemented on other platforms. Second. the `generic' version of a +system-dependent file is used if the makefiles do not find a version +specific to the system you're compiling for. - You must give prominent notice with each copy of the work that the - Library is used in it and that the Library and its use are covered - by this License. You must supply a copy of this License. If the - work during execution displays copyright notices, you must include - the copyright notice for the Library among them, as well as a - reference directing the user to the copy of this License. Also, - you must do one of these things: + If it is possible to implement the routines in a `generic' file in +machine-independent C, using only other machine-independent functions in +the C library, then you should do so. Otherwise, make them stubs. A +"stub" function is a function which cannot be implemented on a +particular machine or operating system. Stub functions always return an +error, and set `errno' to `ENOSYS' (Function not implemented). *Note +Error Reporting::. If you define a stub function, you must place the +statement `stub_warning(FUNCTION)', where FUNCTION is the name of your +function, after its definition; also, you must include the file +`' into your file. This causes the function to be listed +in the installed `', and makes GNU ld warn when the +function is used. - a. Accompany the work with the complete corresponding - machine-readable source code for the Library including - whatever changes were used in the work (which must be - distributed under Sections 1 and 2 above); and, if the work - is an executable linked with the Library, with the complete - machine-readable "work that uses the Library", as object code - and/or source code, so that the user can modify the Library - and then relink to produce a modified executable containing - the modified Library. (It is understood that the user who - changes the contents of definitions files in the Library will - not necessarily be able to recompile the application to use - the modified definitions.) + Some rare functions are only useful on specific systems and aren't +defined at all on others; these do not appear anywhere in the +system-independent source code or makefiles (including the `generic' +directory), only in the system-dependent `Makefile' in the specific +system's subdirectory. - b. Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run - time a copy of the library already present on the user's - computer system, rather than copying library functions into - the executable, and (2) will operate properly with a modified - version of the library, if the user installs one, as long as - the modified version is interface-compatible with the version - that the work was made with. + If you come across a file that is in one of the main source +directories (`string', `stdio', etc.), and you want to write a machine- +or operating system-dependent version of it, move the file into +`sysdeps/generic' and write your new implementation in the appropriate +system-specific subdirectory. Note that if a file is to be +system-dependent, it *must not* appear in one of the main source +directories. - c. Accompany the work with a written offer, valid for at least - three years, to give the same user the materials specified in - Subsection 6a, above, for a charge no more than the cost of - performing this distribution. + There are a few special files that may exist in each subdirectory of +`sysdeps': - d. If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the - above specified materials from the same place. +`Makefile' + A makefile for this machine or operating system, or class of + machine or operating system. This file is included by the library + makefile `Makerules', which is used by the top-level makefile and + the subdirectory makefiles. It can change the variables set in the + including makefile or add new rules. It can use GNU `make' + conditional directives based on the variable `subdir' (see above) + to select different sets of variables and rules for different + sections of the library. It can also set the `make' variable + `sysdep-routines', to specify extra modules to be included in the + library. You should use `sysdep-routines' rather than adding + modules to `routines' because the latter is used in determining + what to distribute for each subdirectory of the main source tree. - e. Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. + Each makefile in a subdirectory in the ordered list of + subdirectories to be searched is included in order. Since several + system-dependent makefiles may be included, each should append to + `sysdep-routines' rather than simply setting it: - For an executable, the required form of the "work that uses the - Library" must include any data and utility programs needed for - reproducing the executable from it. However, as a special - exception, the materials to be distributed need not include - anything that is normally distributed (in either source or binary - form) with the major components (compiler, kernel, and so on) of - the operating system on which the executable runs, unless that - component itself accompanies the executable. + sysdep-routines := $(sysdep-routines) foo bar - It may happen that this requirement contradicts the license - restrictions of other proprietary libraries that do not normally - accompany the operating system. Such a contradiction means you - cannot use both them and the Library together in an executable - that you distribute. +`Subdirs' + This file contains the names of new whole subdirectories under the + top-level library source tree that should be included for this + system. These subdirectories are treated just like the + system-independent subdirectories in the library source tree, such + as `stdio' and `math'. - 7. You may place library facilities that are a work based on the - Library side-by-side in a single library together with other - library facilities not covered by this License, and distribute - such a combined library, provided that the separate distribution - of the work based on the Library and of the other library - facilities is otherwise permitted, and provided that you do these - two things: + Use this when there are completely new sets of functions and header + files that should go into the library for the system this + subdirectory of `sysdeps' implements. For example, + `sysdeps/unix/inet/Subdirs' contains `inet'; the `inet' directory + contains various network-oriented operations which only make sense + to put in the library on systems that support the Internet. - a. Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. +`Dist' + This file contains the names of files (relative to the + subdirectory of `sysdeps' in which it appears) which should be + included in the distribution. List any new files used by rules in + the `Makefile' in the same directory, or header files used by the + source files in that directory. You don't need to list files that + are implementations (either C or assembly source) of routines + whose names are given in the machine-independent makefiles in the + main source tree. - b. Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same - work. +`configure' + This file is a shell script fragment to be run at configuration + time. The top-level `configure' script uses the shell `.' command + to read the `configure' file in each system-dependent directory + chosen, in order. The `configure' files are often generated from + `configure.in' files using Autoconf. - 8. You may not copy, modify, sublicense, link with, or distribute the - Library except as expressly provided under this License. Any - attempt otherwise to copy, modify, sublicense, link with, or - distribute the Library is void, and will automatically terminate - your rights under this License. However, parties who have - received copies, or rights, from you under this License will not - have their licenses terminated so long as such parties remain in - full compliance. + A system-dependent `configure' script will usually add things to + the shell variables `DEFS' and `config_vars'; see the top-level + `configure' script for details. The script can check for + `--with-PACKAGE' options that were passed to the top-level + `configure'. For an option `--with-PACKAGE=VALUE' `configure' + sets the shell variable `with_PACKAGE' (with any dashes in PACKAGE + converted to underscores) to VALUE; if the option is just + `--with-PACKAGE' (no argument), then it sets `with_PACKAGE' to + `yes'. - 9. You are not required to accept this License, since you have not - signed it. However, nothing else grants you permission to modify - or distribute the Library or its derivative works. These actions - are prohibited by law if you do not accept this License. - Therefore, by modifying or distributing the Library (or any work - based on the Library), you indicate your acceptance of this - License to do so, and all its terms and conditions for copying, - distributing or modifying the Library or works based on it. +`configure.in' + This file is an Autoconf input fragment to be processed into the + file `configure' in this subdirectory. *Note Introduction: + (autoconf.info)Introduction, for a description of Autoconf. You + should write either `configure' or `configure.in', but not both. + The first line of `configure.in' should invoke the `m4' macro + `GLIBC_PROVIDES'. This macro does several `AC_PROVIDE' calls for + Autoconf macros which are used by the top-level `configure' + script; without this, those macros might be invoked again + unnecessarily by Autoconf. - 10. Each time you redistribute the Library (or any work based on the - Library), the recipient automatically receives a license from the - original licensor to copy, distribute, link with or modify the - Library subject to these terms and conditions. You may not impose - any further restrictions on the recipients' exercise of the rights - granted herein. You are not responsible for enforcing compliance - by third parties with this License. + That is the general system for how system-dependencies are isolated. - 11. If, as a consequence of a court judgment or allegation of patent - infringement or for any other reason (not limited to patent - issues), conditions are imposed on you (whether by court order, - agreement or otherwise) that contradict the conditions of this - License, they do not excuse you from the conditions of this - License. If you cannot distribute so as to satisfy simultaneously - your obligations under this License and any other pertinent - obligations, then as a consequence you may not distribute the - Library at all. For example, if a patent license would not permit - royalty-free redistribution of the Library by all those who - receive copies directly or indirectly through you, then the only - way you could satisfy both it and this License would be to refrain - entirely from distribution of the Library. +* Menu: - If any portion of this section is held invalid or unenforceable - under any particular circumstance, the balance of the section is - intended to apply, and the section as a whole is intended to apply - in other circumstances. +* Hierarchy Conventions:: The layout of the `sysdeps' hierarchy. +* Porting to Unix:: Porting the library to an average + Unix-like system. - It is not the purpose of this section to induce you to infringe any - patents or other property right claims or to contest validity of - any such claims; this section has the sole purpose of protecting - the integrity of the free software distribution system which is - implemented by public license practices.

If the distribution and/or use of the Library is restricted in - certain countries either by patents or by copyrighted interfaces, - the original copyright holder who places the Library under this - License may add an explicit geographical distribution limitation - excluding those countries, so that distribution is permitted only - in or among countries not thus excluded. In such case, this - License incorporates the limitation as if written in the body of - this License. + A GNU configuration name has three parts: the CPU type, the +manufacturer's name, and the operating system. `configure' uses these +to pick the list of system-dependent directories to look for. If the +`--nfp' option is _not_ passed to `configure', the directory +`MACHINE/fpu' is also used. The operating system often has a "base +operating system"; for example, if the operating system is `Linux', the +base operating system is `unix/sysv'. The algorithm used to pick the +list of directories is simple: `configure' makes a list of the base +operating system, manufacturer, CPU type, and operating system, in that +order. It then concatenates all these together with slashes in +between, to produce a directory name; for example, the configuration +`i686-linux-gnu' results in `unix/sysv/linux/i386/i686'. `configure' +then tries removing each element of the list in turn, so +`unix/sysv/linux' and `unix/sysv' are also tried, among others. Since +the precise version number of the operating system is often not +important, and it would be very inconvenient, for example, to have +identical `irix6.2' and `irix6.3' directories, `configure' tries +successively less specific operating system names by removing trailing +suffixes starting with a period. - 13.

There are +variations between different machines, and variations in what +facilities are provided by the kernel. But the interface to the +operating system facilities is, for the most part, pretty uniform and +simple. + + The code for Unix systems is in the directory `unix', at the top +level of the `sysdeps' hierarchy. This directory contains +subdirectories (and subdirectory trees) for various Unix variants. + + The functions which are system calls in most Unix systems are +implemented in assembly code, which is generated automatically from +specifications in files named `syscalls.list'. There are several such +files, one in `sysdeps/unix' and others in its subdirectories. Some +special system calls are implemented in files that are named with a +suffix of `.S'; for example, `_exit.S'. Files ending in `.S' are run +through the C preprocessor before being fed to the assembler. + + These files all use a set of macros that should be defined in +`sysdep.h'. The `sysdep.h' file in `sysdeps/unix' partially defines +them; a `sysdep.h' file in another directory must finish defining them +for the particular machine and operating system variant. See +`sysdeps/unix/sysdep.h' and the machine-specific `sysdep.h' +implementations to see what these macros are and what they should do. + + The system-specific makefile for the `unix' directory +(`sysdeps/unix/Makefile') gives rules to generate several files from +the Unix system you are building the library on (which is assumed to be +the target system you are building the library _for_). All the +generated files are put in the directory where the object files are +kept; they should not affect the source tree itself. The files +generated are `ioctls.h', `errnos.h', `sys/param.h', and `errlist.c' +(for the `stdio' section of the library). diff -durpN glibc-2.2.4/manual/libc.info-55 glibc-2.2.5/manual/libc.info-55 --- glibc-2.2.4/manual/libc.info-55 Mon Aug 13 15:03:42 2001 +++ glibc-2.2.5/manual/libc.info-55 Sun Jan 20 19:28:42 2002 @@ -1,4 +1,4 @@ -This is libc.info, produced by makeinfo version 4.0c from libc.texinfo. +This is libc.info, produced by makeinfo version 4.0 from libc.texinfo.

A copy that is not "Transparent" is called "Opaque". + * The `mktime' function was contributed by Paul Eggert. - Examples of suitable formats for Transparent copies include plain - ASCII without markup, Texinfo input format, LaTeX input format, - SGML or XML using a publicly available DTD, and - standard-conforming simple HTML designed for human modification. - Opaque formats include PostScript, PDF, proprietary formats that - can be read and edited only by proprietary word processors, SGML - or XML for which the DTD and/or processing tools are not generally - available, and the machine-generated HTML produced by some word - processors for output purposes only. + * The port to the Sequent Symmetry running Dynix version 3 + (`i386-sequent-bsd') was contributed by Jason Merrill. - The "Title Page" means, for a printed book, the title page itself, - plus such following pages as are needed to hold, legibly, the - material this License requires to appear in the title page. For - works in formats which do not have any title page as such, "Title - Page" means the text near the most prominent appearance of the - work's title, preceding the beginning of the body of the text. + * The timezone support code is derived from the public-domain + timezone package by Arthur David Olson and his many contributors. - 2. VERBATIM COPYING + * The port to the DEC Alpha running OSF/1 (`alpha-dec-osf1') was + contributed by Brendan Kehoe, using some code written by Roland + McGrath. - You may copy and distribute the Document in any medium, either - commercially or noncommercially, provided that this License, the - copyright notices, and the license notice saying this License - applies to the Document are reproduced in all copies, and that you - add no other conditions whatsoever to those of this License. You - may not use technical measures to obstruct or control the reading - or further copying of the copies you make or distribute. However, - you may accept compensation in exchange for copies. If you - distribute a large enough number of copies you must also follow - the conditions in section 3. + * The port to SGI machines running Irix 4 (`mips-sgi-irix4') was + contributed by Tom Quinn. - You may also lend copies, under the same conditions stated above, - and you may publicly display copies. + * The port of the Mach and Hurd code to the MIPS architecture + (`mips-ANYTHING-gnu') was contributed by Kazumoto Kojima. - 3. COPYING IN QUANTITY + * The floating-point printing function used by `printf' and friends + and the floating-point reading function used by `scanf', `strtod' + and friends were written by Ulrich Drepper. The multi-precision + integer functions used in those functions are taken from GNU MP, + which was contributed by Torbjo"rn Granlund. - If you publish printed copies of the Document numbering more than - 100, and the Document's license notice requires Cover Texts, you - must enclose the copies in covers that carry, clearly and legibly, - all these Cover Texts: Front-Cover Texts on the front cover, and - Back-Cover Texts on the back cover. Both covers must also clearly - and legibly identify you as the publisher of these copies. The - front cover must present the full title with all words of the - title equally prominent and visible. You may add other material - on the covers in addition. Copying with changes limited to the - covers, as long as they preserve the title of the Document and - satisfy these conditions, can be treated as verbatim copying in - other respects. + * The internationalization support in the library, and the support + programs `locale' and `localedef', were written by Ulrich Drepper. + Ulrich Drepper adapted the support code for message catalogs + (`libintl.h', etc.) from the GNU `gettext' package, which he also + wrote. He also contributed the `catgets' support and the entire + suite of multi-byte and wide-character support functions + (`wctype.h', `wchar.h', etc.). - If the required texts for either cover are too voluminous to fit - legibly, you should put the first ones listed (as many as fit - reasonably) on the actual cover, and continue the rest onto - adjacent pages. + * The implementations of the `nsswitch.conf' mechanism and the files + and DNS backends for it were designed and written by Ulrich + Drepper and Roland McGrath, based on a backend interface defined + by Peter Eriksson. - If you publish or distribute Opaque copies of the Document - numbering more than 100, you must either include a - machine-readable Transparent copy along with each Opaque copy, or - state in or with each Opaque copy a publicly-accessible - computer-network location containing a complete Transparent copy - of the Document, free of added material, which the general - network-using public has access to download anonymously at no - charge using public-standard network protocols. If you use the - latter option, you must take reasonably prudent steps, when you - begin distribution of Opaque copies in quantity, to ensure that - this Transparent copy will remain thus accessible at the stated - location until at least one year after the last time you - distribute an Opaque copy (directly or through your agents or - retailers) of that edition to the public. + * The port to Linux i386/ELF (`i386-ANYTHING-linux') was contributed + by Ulrich Drepper, based in large part on work done in Hongjiu + Lu's Linux version of the GNU C Library. - It is requested, but not required, that you contact the authors of - the Document well before redistributing any large number of - copies, to give them a chance to provide you with an updated - version of the Document. + * The port to Linux/m68k (`m68k-ANYTHING-linux') was contributed by + Andreas Schwab. - 4. MODIFICATIONS + * The ports to Linux/ARM (`arm-ANYTHING-linuxaout') and ARM + standalone (`arm-ANYTHING-none'), as well as parts of the IPv6 + support code, were contributed by Philip Blundell. - You may copy and distribute a Modified Version of the Document - under the conditions of sections 2 and 3 above, provided that you - release the Modified Version under precisely this License, with - the Modified Version filling the role of the Document, thus - licensing distribution and modification of the Modified Version to - whoever possesses a copy of it. In addition, you must do these - things in the Modified Version: + * Richard Henderson contributed the ELF dynamic linking code and + other support for the Alpha processor. - A. Use in the Title Page (and on the covers, if any) a title - distinct from that of the Document, and from those of - previous versions (which should, if there were any, be listed - in the History section of the Document). You may use the - same title as a previous version if the original publisher of - that version gives permission. + * David Mosberger-Tang contributed the port to Linux/Alpha + (`alpha-ANYTHING-linux'). - B. List on the Title Page, as authors, one or more persons or - entities responsible for authorship of the modifications in - the Modified Version, together with at least five of the - principal authors of the Document (all of its principal - authors, if it has less than five). + * The port to Linux on PowerPC (`powerpc-ANYTHING-linux') was + contributed by Geoffrey Keating. - C. State on the Title page the name of the publisher of the - Modified Version, as the publisher. + * Miles Bader wrote the argp argument-parsing package, and the + argz/envz interfaces. - D. Preserve all the copyright notices of the Document. + * Stephen R. van den Berg contributed a highly-optimized `strstr' + function. - E. Add an appropriate copyright notice for your modifications - adjacent to the other copyright notices. + * Ulrich Drepper contributed the `hsearch' and `drand48' families of + functions; reentrant `...`_r'' versions of the `random' family; + System V shared memory and IPC support code; and several + highly-optimized string functions for iX86 processors. - F. Include, immediately after the copyright notices, a license - notice giving the public permission to use the Modified - Version under the terms of this License, in the form shown in - the Addendum below. + * The math functions are taken from `fdlibm-5.1' by Sun + Microsystems, as modified by J.T. Conklin, Ian Lance Taylor, + Ulrich Drepper, Andreas Schwab, and Roland McGrath. - G. Preserve in that license notice the full lists of Invariant - Sections and required Cover Texts given in the Document's - license notice. + * The `libio' library used to implement `stdio' functions on some + platforms was written by Per Bothner and modified by Ulrich + Drepper. - H. Include an unaltered copy of this License. + * Eric Youngdale and Ulrich Drepper implemented versioning of + objects on symbol level. - I. Preserve the section entitled "History", and its title, and - add to it an item stating at least the title, year, new - authors, and publisher of the Modified Version as given on - the Title Page. If there is no section entitled "History" in - the Document, create one stating the title, year, authors, - and publisher of the Document as given on its Title Page, - then add an item describing the Modified Version as stated in - the previous sentence. + * Thorsten Kukuk provided an implementation for NIS (YP) and NIS+, + securelevel 0, 1 and 2. - J. Preserve the network location, if any, given in the Document - for public access to a Transparent copy of the Document, and - likewise the network locations given in the Document for - previous versions it was based on. These may be placed in - the "History" section. You may omit a network location for a - work that was published at least four years before the - Document itself, or if the original publisher of the version - it refers to gives permission. + * Andreas Jaeger provided a test suite for the math library. - K. In any section entitled "Acknowledgments" or "Dedications", - preserve the section's title, and preserve in the section all - the substance and tone of each of the contributor - acknowledgments and/or dedications given therein. + * Mark Kettenis implemented the utmpx interface and an utmp daemon. - L.

To do this, - add their titles to the list of Invariant Sections in the Modified - Version's license notice. These titles must be distinct from any - other section titles. + * Mark Kettenis provided a Hesiod NSS module. - You may add a section entitled "Endorsements", provided it contains - nothing but endorsements of your Modified Version by various - parties--for example, statements of peer review or that the text - has been approved by an organization as the authoritative - definition of a standard. + * The Internet-related code (most of the `inet' subdirectory) and + several other miscellaneous functions and header files have been + included from 4.4 BSD with little or no modification. - You may add a passage of up to five words as a Front-Cover Text, - and a passage of up to 25 words as a Back-Cover Text, to the end - of the list of Cover Texts in the Modified Version.

Many of our most important programs do +not come with free reference manuals and free introductory texts. +Documentation is an essential part of any software package; when an +important free software package does not come with a free manual and a +free tutorial, that is a major gap. We have many such gaps today. + + Consider Perl, for instance. The tutorial manuals that people +normally use are non-free. How did this come about? Because the +authors of those manuals published them with restrictive terms--no +copying, no modification, source files not available--which exclude +them from the free software world. + + That wasn't the first time this sort of thing happened, and it was +far from the last. Many times we have heard a GNU user eagerly +describe a manual that he is writing, his intended contribution to the +community, only to learn that he had ruined everything by signing a +publication contract to make it non-free. + + Free documentation, like free software, is a matter of freedom, not +price. The problem with the non-free manual is not that publishers +charge a price for printed copies--that in itself is fine. (The Free +Software Foundation sells printed copies of manuals, too.) The problem +is the restrictions on the use of the manual. Free manuals are +available in source code form, and give you permission to copy and +modify. Non-free manuals do not allow this. + + The criteria of freedom for a free manual are roughly the same as for +free software. Redistribution (including the normal kinds of +commercial redistribution) must be permitted, so that the manual can +accompany every copy of the program, both on-line and on paper. + + Permission for modification of the technical content is crucial too. +When people modify the software, adding or changing features, if they +are conscientious they will change the manual too--so they can provide +accurate and clear documentation for the modified program. A manual +that leaves you no choice but to write a new manual to document a +changed version of the program is not really available to our community. + + Some kinds of limits on the way modification is handled are +acceptable. For example, requirements to preserve the original +author's copyright notice, the distribution terms, or the list of +authors, are ok. It is also no problem to require modified versions to +include notice that they were modified. Even entire sections that may +not be deleted or changed are acceptable, as long as they deal with +nontechnical topics (like this one). These kinds of restrictions are +acceptable because they don't obstruct the community's normal use of +the manual. + + However, it must be possible to modify all the _technical_ content +of the manual, and then distribute the result in all the usual media, +through all the usual channels. Otherwise, the restrictions obstruct +the use of the manual, it is not free, and we need another manual to +replace it. + + Please spread the word about this issue. Our community continues to +lose manuals to proprietary publishing. If we spread the word that +free software needs free reference manuals and free tutorials, perhaps +the next person who wants to contribute by writing documentation will +realize, before it is too late, that only free manuals contribute to +the free software community. + + If you are writing documentation, please insist on publishing it +under the GNU Free Documentation License or another free documentation +license. Remember that this decision requires your approval--you don't +have to let the publisher decide. Some commercial publishers will use +a free license if you insist, but they will not propose the option; it +is up to you to raise the issue and say firmly that this is what you +want. If the publisher you are dealing with refuses, please try other +publishers. If you're not sure whether a proposed license is free, +write to . + + You can encourage commercial publishers to sell more free, copylefted +manuals and tutorials by buying them, and particularly by buying copies +from the publishers that paid for their writing or for major +improvements.

copies + of this license document, but changing it is not allowed. + + [This is the first released version of the Lesser GPL. It also counts + as the successor of the GNU Library Public License, version 2, hence the + version number 2.1.] + +Preamble +-------- + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software--typically libraries--of the Free +Software Foundation and other authors who decide to use it. You can use +it too, but we suggest you first think carefully about whether this +license or the ordinary General Public License is the better strategy to +use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of it +in new free programs; and that you are informed that you can do these +things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know that +what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and is +quite different from the ordinary General Public License. We use this +license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does _Less_ to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it +becomes a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of free +software. For example, permission to use the GNU C Library in non-free +programs enables many more people to use the whole GNU operating +system, as well as its variant, the GNU/Linux operating system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run that +program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other + program which contains a notice placed by the copyright holder or + other authorized party saying it may be distributed under the + terms of this Lesser General Public License (also called "this + License"). Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data + prepared so as to be conveniently linked with application programs + (which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work + which has been distributed under these terms. A "work based on the + Library" means either the Library or any derivative work under + copyright law: that is to say, a work containing the Library or a + portion of it, either verbatim or with modifications and/or + translated straightforwardly into another language. (Hereinafter, + translation is included without limitation in the term + "modification".) + + "Source code" for a work means the preferred form of the work for + making modifications to it. For a library, complete source code + means all the source code for all modules it contains, plus any + associated interface definition files, plus the scripts used to + control compilation and installation of the library. + + Activities other than copying, distribution and modification are + not covered by this License; they are outside its scope. The act + of running a program using the Library is not restricted, and + output from such a program is covered only if its contents + constitute a work based on the Library (independent of the use of + the Library in a tool for writing it). Whether that is true + depends on what the Library does and what the program that uses + the Library does. + + 1. You may copy and distribute verbatim copies of the Library's + complete source code as you receive it, in any medium, provided + that you conspicuously and appropriately publish on each copy an + appropriate copyright notice and disclaimer of warranty; keep + intact all the notices that refer to this License and to the + absence of any warranty; and distribute a copy of this License + along with the Library. + + You may charge a fee for the physical act of transferring a copy, + and you may at your option offer warranty protection in exchange + for a fee. + + 2. You may modify your copy or copies of the Library or any portion + of it, thus forming a work based on the Library, and copy and + distribute such modifications or work under the terms of Section 1 + above, provided that you also meet all of these conditions: + + a. The modified work must itself be a software library. + + b. You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c. You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d. If a facility in the modified Library refers to a function or + a table of data to be supplied by an application program that + uses the facility, other than as an argument passed when the + facility is invoked, then you must make a good faith effort + to ensure that, in the event an application does not supply + such function or table, the facility still operates, and + performs whatever part of its purpose remains meaningful. + + (For example, a function in a library to compute square roots + has a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function + must be optional: if the application does not supply it, the + square root function must still compute square roots.) + + These requirements apply to the modified work as a whole. If + identifiable sections of that work are not derived from the + Library, and can be reasonably considered independent and separate + works in themselves, then this License, and its terms, do not + apply to those sections when you distribute them as separate + works. But when you distribute the same sections as part of a + whole which is a work based on the Library, the distribution of + the whole must be on the terms of this License, whose permissions + for other licensees extend to the entire whole, and thus to each + and every part regardless of who wrote it. + + Thus, it is not the intent of this section to claim rights or + contest your rights to work written entirely by you; rather, the + intent is to exercise the right to control the distribution of + derivative or collective works based on the Library. + + In addition, mere aggregation of another work not based on the + Library with the Library (or with a work based on the Library) on + a volume of a storage or distribution medium does not bring the + other work under the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public + License instead of this License to a given copy of the Library. + To do this, you must alter all the notices that refer to this + License, so that they refer to the ordinary GNU General Public + License, version 2, instead of to this License. (If a newer + version than version 2 of the ordinary GNU General Public License + has appeared, then you can specify that version instead if you + wish.) Do not make any other change in these notices. + + Once this change is made in a given copy, it is irreversible for + that copy, so the ordinary GNU General Public License applies to + all subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of + the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or + derivative of it, under Section 2) in object code or executable + form under the terms of Sections 1 and 2 above provided that you + accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software + interchange. + + If distribution of object code is made by offering access to copy + from a designated place, then offering equivalent access to copy + the source code from the same place satisfies the requirement to + distribute the source code, even though third parties are not + compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the + Library, but is designed to work with the Library by being + compiled or linked with it, is called a "work that uses the + Library". Such a work, in isolation, is not a derivative work of + the Library, and therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library + creates an executable that is a derivative of the Library (because + it contains portions of the Library), rather than a "work that + uses the library". The executable is therefore covered by this + License. Section 6 states terms for distribution of such + executables. + + When a "work that uses the Library" uses material from a header + file that is part of the Library, the object code for the work may + be a derivative work of the Library even though the source code is + not. Whether this is true is especially significant if the work + can be linked without the Library, or if the work is itself a + library. The threshold for this to be true is not precisely + defined by law. + + If such an object file uses only numerical parameters, data + structure layouts and accessors, and small macros and small inline + functions (ten lines or less in length), then the use of the object + file is unrestricted, regardless of whether it is legally a + derivative work. (Executables containing this object code plus + portions of the Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may + distribute the object code for the work under the terms of Section + 6. Any executables containing that work also fall under Section 6, + whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or + link a "work that uses the Library" with the Library to produce a + work containing portions of the Library, and distribute that work + under terms of your choice, provided that the terms permit + modification of the work for the customer's own use and reverse + engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the + Library is used in it and that the Library and its use are covered + by this License. You must supply a copy of this License. If the + work during execution displays copyright notices, you must include + the copyright notice for the Library among them, as well as a + reference directing the user to the copy of this License. Also, + you must do one of these things: + + a. Accompany the work with the complete corresponding + machine-readable source code for the Library including + whatever changes were used in the work (which must be + distributed under Sections 1 and 2 above); and, if the work + is an executable linked with the Library, with the complete + machine-readable "work that uses the Library", as object code + and/or source code, so that the user can modify the Library + and then relink to produce a modified executable containing + the modified Library. (It is understood that the user who + changes the contents of definitions files in the Library will + not necessarily be able to recompile the application to use + the modified definitions.) + + b. Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run + time a copy of the library already present on the user's + computer system, rather than copying library functions into + the executable, and (2) will operate properly with a modified + version of the library, if the user installs one, as long as + the modified version is interface-compatible with the version + that the work was made with. + + c. Accompany the work with a written offer, valid for at least + three years, to give the same user the materials specified in + Subsection 6a, above, for a charge no more than the cost of + performing this distribution. + + d. If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the + above specified materials from the same place. + + e. Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the + Library" must include any data and utility programs needed for + reproducing the executable from it. However, as a special + exception, the materials to be distributed need not include + anything that is normally distributed (in either source or binary + form) with the major components (compiler, kernel, and so on) of + the operating system on which the executable runs, unless that + component itself accompanies the executable. + + It may happen that this requirement contradicts the license + restrictions of other proprietary libraries that do not normally + accompany the operating system. Such a contradiction means you + cannot use both them and the Library together in an executable + that you distribute. + + 7. You may place library facilities that are a work based on the + Library side-by-side in a single library together with other + library facilities not covered by this License, and distribute + such a combined library, provided that the separate distribution + of the work based on the Library and of the other library + facilities is otherwise permitted, and provided that you do these + two things: + + a. Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b. Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same + work. + + 8. You may not copy, modify, sublicense, link with, or distribute the + Library except as expressly provided under this License. Any + attempt otherwise to copy, modify, sublicense, link with, or + distribute the Library is void, and will automatically terminate + your rights under this License. However, parties who have + received copies, or rights, from you under this License will not + have their licenses terminated so long as such parties remain in + full compliance. + + 9. You are not required to accept this License, since you have not + signed it. However, nothing else grants you permission to modify + or distribute the Library or its derivative works. These actions + are prohibited by law if you do not accept this License. + Therefore, by modifying or distributing the Library (or any work + based on the Library), you indicate your acceptance of this + License to do so, and all its terms and conditions for copying, + distributing or modifying the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the + Library), the recipient automatically receives a license from the + original licensor to copy, distribute, link with or modify the + Library subject to these terms and conditions. You may not impose + any further restrictions on the recipients' exercise of the rights + granted herein. You are not responsible for enforcing compliance + by third parties with this License. + + 11. If, as a consequence of a court judgment or allegation of patent + infringement or for any other reason (not limited to patent + issues), conditions are imposed on you (whether by court order, + agreement or otherwise) that contradict the conditions of this + License, they do not excuse you from the conditions of this + License. If you cannot distribute so as to satisfy simultaneously + your obligations under this License and any other pertinent + obligations, then as a consequence you may not distribute the + Library at all. For example, if a patent license would not permit + royalty-free redistribution of the Library by all those who + receive copies directly or indirectly through you, then the only + way you could satisfy both it and this License would be to refrain + entirely from distribution of the Library. + + If any portion of this section is held invalid or unenforceable + under any particular circumstance, the balance of the section is + intended to apply, and the section as a whole is intended to apply + in other circumstances. + + It is not the purpose of this section to induce you to infringe any + patents or other property right claims or to contest validity of + any such claims; this section has the sole purpose of protecting + the integrity of the free software distribution system which is + implemented by public license practices. Many people have made + generous contributions to the wide range of software distributed + through that system in reliance on consistent application of that + system; it is up to the author/donor to decide if he or she is + willing to distribute software through any other system and a + licensee cannot impose that choice. + + This section is intended to make thoroughly clear what is believed + to be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in + certain countries either by patents or by copyrighted interfaces, + the original copyright holder who places the Library under this + License may add an explicit geographical distribution limitation + excluding those countries, so that distribution is permitted only + in or among countries not thus excluded. In such case, this + License incorporates the limitation as if written in the body of + this License. + + 13. The Free Software Foundation may publish revised and/or new + versions of the Lesser General Public License from time to time. + Such new versions will be similar in spirit to the present version, + but may differ in detail to address new problems or concerns. + + Each version is given a distinguishing version number. If the + Library specifies a version number of this License which applies + to it and "any later version", you have the option of following + the terms and conditions either of that version or of any later + version published by the Free Software Foundation. If the Library + does not specify a license version number, you may choose any + version ever published by the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free + programs whose distribution conditions are incompatible with these, + write to the author to ask for permission. For software which is + copyrighted by the Free Software Foundation, write to the Free + Software Foundation; we sometimes make exceptions for this. Our + decision will be guided by the two goals of preserving the free + status of all derivatives of our free software and of promoting + the sharing and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO + WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE + LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT + HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT + WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT + NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND + FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE + QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE + LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY + SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY + MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE + LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, + INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR + INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF + DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU + OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY + OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN + ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Libraries +---------------------------------------------- + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of +the ordinary General Public License). + + To apply these terms, attach the following notices to the library. +It is safest to attach them to the start of each source file to most +effectively convey the exclusion of warranty; and each file should have +at least the "copyright" line and a pointer to where the full notice is +found. + + ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES. + Copyright (C) YEAR NAME OF AUTHOR + + This library is free software; you can redistribute it and/or modify it + under the terms of the GNU Lesser General Public License as published by + the Free Software Foundation; either version 2.1 of the License, or (at + your option) any later version. + + This library is distributed in the hope that it will be useful, but + WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU + Lesser General Public License for more details. + + You should have received a copy of the GNU Lesser General Public + License along with this library; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307, + USA. + + Also add information on how to contact you by electronic and paper +mail. + + You should also get your employer (if you work as a programmer) or +your school, if any, to sign a "copyright disclaimer" for the library, +if necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the library + `Frob' (a library for tweaking knobs) written by James Random Hacker. + + SIGNATURE OF TY COON, 1 April 1990 + Ty Coon, President of Vice + + That's all there is to it! + + +File: libc.info, Node: Documentation License, Next: Concept Index, Prev: Copying, Up: Top + +GNU Free Documentation License +****************************** + + Version 1.1, March 2000 + + Copyright (C) 2000 Free Software Foundation, Inc. + 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA + + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + 0. PREAMBLE + + The purpose of this License is to make a manual, textbook, or other + written document "free" in the sense of freedom: to assure everyone + the effective freedom to copy and redistribute it, with or without + modifying it, either commercially or noncommercially. Secondarily, + this License preserves for the author and publisher a way to get + credit for their work, while not being considered responsible for + modifications made by others. + + This License is a kind of "copyleft", which means that derivative + works of the document must themselves be free in the same sense. + It complements the GNU General Public License, which is a copyleft + license designed for free software. + + We have designed this License in order to use it for manuals for + free software, because free software needs free documentation: a + free program should come with manuals providing the same freedoms + that the software does. But this License is not limited to + software manuals; it can be used for any textual work, regardless + of subject matter or whether it is published as a printed book. + We recommend this License principally for works whose purpose is + instruction or reference. + + 1. APPLICABILITY AND DEFINITIONS + + This License applies to any manual or other work that contains a + notice placed by the copyright holder saying it can be distributed + under the terms of this License. The "Document", below, refers to + any such manual or work. Any member of the public is a licensee, + and is addressed as "you". + + A "Modified Version" of the Document means any work containing the + Document or a portion of it, either copied verbatim, or with + modifications and/or translated into another language. + + A "Secondary Section" is a named appendix or a front-matter + section of the Document that deals exclusively with the + relationship of the publishers or authors of the Document to the + Document's overall subject (or to related matters) and contains + nothing that could fall directly within that overall subject. + (For example, if the Document is in part a textbook of + mathematics, a Secondary Section may not explain any mathematics.) + The relationship could be a matter of historical connection with + the subject or with related matters, or of legal, commercial, + philosophical, ethical or political position regarding them. + + The "Invariant Sections" are certain Secondary Sections whose + titles are designated, as being those of Invariant Sections, in + the notice that says that the Document is released under this + License. + + The "Cover Texts" are certain short passages of text that are + listed, as Front-Cover Texts or Back-Cover Texts, in the notice + that says that the Document is released under this License. + + A "Transparent" copy of the Document means a machine-readable copy, + represented in a format whose specification is available to the + general public, whose contents can be viewed and edited directly + and straightforwardly with generic text editors or (for images + composed of pixels) generic paint programs or (for drawings) some + widely available drawing editor, and that is suitable for input to + text formatters or for automatic translation to a variety of + formats suitable for input to text formatters. A copy made in an + otherwise Transparent file format whose markup has been designed + to thwart or discourage subsequent modification by readers is not + Transparent. A copy that is not "Transparent" is called "Opaque". + + Examples of suitable formats for Transparent copies include plain + ASCII without markup, Texinfo input format, LaTeX input format, + SGML or XML using a publicly available DTD, and + standard-conforming simple HTML designed for human modification. + Opaque formats include PostScript, PDF, proprietary formats that + can be read and edited only by proprietary word processors, SGML + or XML for which the DTD and/or processing tools are not generally + available, and the machine-generated HTML produced by some word + processors for output purposes only. + + The "Title Page" means, for a printed book, the title page itself, + plus such following pages as are needed to hold, legibly, the + material this License requires to appear in the title page. For + works in formats which do not have any title page as such, "Title + Page" means the text near the most prominent appearance of the + work's title, preceding the beginning of the body of the text. + + 2. VERBATIM COPYING + + You may copy and distribute the Document in any medium, either + commercially or noncommercially, provided that this License, the + copyright notices, and the license notice saying this License + applies to the Document are reproduced in all copies, and that you + add no other conditions whatsoever to those of this License. You + may not use technical measures to obstruct or control the reading + or further copying of the copies you make or distribute. However, + you may accept compensation in exchange for copies. If you + distribute a large enough number of copies you must also follow + the conditions in section 3. + + You may also lend copies, under the same conditions stated above, + and you may publicly display copies. + + 3. COPYING IN QUANTITY + + If you publish printed copies of the Document numbering more than + 100, and the Document's license notice requires Cover Texts, you + must enclose the copies in covers that carry, clearly and legibly, + all these Cover Texts: Front-Cover Texts on the front cover, and + Back-Cover Texts on the back cover. Both covers must also clearly + and legibly identify you as the publisher of these copies. The + front cover must present the full title with all words of the + title equally prominent and visible. You may add other material + on the covers in addition. Copying with changes limited to the + covers, as long as they preserve the title of the Document and + satisfy these conditions, can be treated as verbatim copying in + other respects. + + If the required texts for either cover are too voluminous to fit + legibly, you should put the first ones listed (as many as fit + reasonably) on the actual cover, and continue the rest onto + adjacent pages. + + If you publish or distribute Opaque copies of the Document + numbering more than 100, you must either include a + machine-readable Transparent copy along with each Opaque copy, or + state in or with each Opaque copy a publicly-accessible + computer-network location containing a complete Transparent copy + of the Document, free of added material, which the general + network-using public has access to download anonymously at no + charge using public-standard network protocols. If you use the + latter option, you must take reasonably prudent steps, when you + begin distribution of Opaque copies in quantity, to ensure that + this Transparent copy will remain thus accessible at the stated + location until at least one year after the last time you + distribute an Opaque copy (directly or through your agents or + retailers) of that edition to the public. + + It is requested, but not required, that you contact the authors of + the Document well before redistributing any large number of + copies, to give them a chance to provide you with an updated + version of the Document. + + 4. MODIFICATIONS + + You may copy and distribute a Modified Version of the Document + under the conditions of sections 2 and 3 above, provided that you + release the Modified Version under precisely this License, with + the Modified Version filling the role of the Document, thus + licensing distribution and modification of the Modified Version to + whoever possesses a copy of it. In addition, you must do these + things in the Modified Version: + + A. Use in the Title Page (and on the covers, if any) a title + distinct from that of the Document, and from those of + previous versions (which should, if there were any, be listed + in the History section of the Document). You may use the + same title as a previous version if the original publisher of + that version gives permission. + + B. List on the Title Page, as authors, one or more persons or + entities responsible for authorship of the modifications in + the Modified Version, together with at least five of the + principal authors of the Document (all of its principal + authors, if it has less than five). + + C. State on the Title page the name of the publisher of the + Modified Version, as the publisher. + + D. Preserve all the copyright notices of the Document. + + E. Add an appropriate copyright notice for your modifications + adjacent to the other copyright notices. + + F. Include, immediately after the copyright notices, a license + notice giving the public permission to use the Modified + Version under the terms of this License, in the form shown in + the Addendum below. + + G. Preserve in that license notice the full lists of Invariant + Sections and required Cover Texts given in the Document's + license notice. + + H. Include an unaltered copy of this License. + + I. Preserve the section entitled "History", and its title, and + add to it an item stating at least the title, year, new + authors, and publisher of the Modified Version as given on + the Title Page. If there is no section entitled "History" in + the Document, create one stating the title, year, authors, + and publisher of the Document as given on its Title Page, + then add an item describing the Modified Version as stated in + the previous sentence. + + J. Preserve the network location, if any, given in the Document + for public access to a Transparent copy of the Document, and + likewise the network locations given in the Document for + previous versions it was based on. These may be placed in + the "History" section. You may omit a network location for a + work that was published at least four years before the + Document itself, or if the original publisher of the version + it refers to gives permission. + + K. In any section entitled "Acknowledgments" or "Dedications", + preserve the section's title, and preserve in the section all + the substance and tone of each of the contributor + acknowledgments and/or dedications given therein. + + L. Preserve all the Invariant Sections of the Document, + unaltered in their text and in their titles. Section numbers + or the equivalent are not considered part of the section + titles. + + M. Delete any section entitled "Endorsements". Such a section + may not be included in the Modified Version. + + N. Do not retitle any existing section as "Endorsements" or to + conflict in title with any Invariant Section. + + If the Modified Version includes new front-matter sections or + appendices that qualify as Secondary Sections and contain no + material copied from the Document, you may at your option + designate some or all of these sections as invariant. To do this, + add their titles to the list of Invariant Sections in the Modified + Version's license notice. These titles must be distinct from any + other section titles. + + You may add a section entitled "Endorsements", provided it contains + nothing but endorsements of your Modified Version by various + parties--for example, statements of peer review or that the text + has been approved by an organization as the authoritative + definition of a standard. + + You may add a passage of up to five words as a Front-Cover Text, + and a passage of up to 25 words as a Back-Cover Text, to the end + of the list of Cover Texts in the Modified Version. Only one + passage of Front-Cover Text and one of Back-Cover Text may be + added by (or through arrangements made by) any one entity. If the + Document already includes a cover text for the same cover, + previously added by you or by arrangement made by the same entity + you are acting on behalf of, you may not add another; but you may + replace the old one, on explicit permission from the previous + publisher that added the old one. + + The author(s) and publisher(s) of the Document do not by this + License give permission to use their names for publicity for or to + assert or imply endorsement of any Modified Version. + + 5. COMBINING DOCUMENTS + + You may combine the Document with other documents released under + this License, under the terms defined in section 4 above for + modified versions, provided that you include in the combination + all of the Invariant Sections of all of the original documents, + unmodified, and list them all as Invariant Sections of your + combined work in its license notice. + + The combined work need only contain one copy of this License, and + multiple identical Invariant Sections may be replaced with a single + copy. If there are multiple Invariant Sections with the same name + but different contents, make the title of each such section unique + by adding at the end of it, in parentheses, the name of the + original author or publisher of that section if known, or else a + unique number. Make the same adjustment to the section titles in + the list of Invariant Sections in the license notice of the + combined work. + + In the combination, you must combine any sections entitled + "History" in the various original documents, forming one section + entitled "History"; likewise combine any sections entitled + "Acknowledgments", and any sections entitled "Dedications". You + must delete all sections entitled "Endorsements." + + 6. COLLECTIONS OF DOCUMENTS + + You may make a collection consisting of the Document and other + documents released under this License, and replace the individual + copies of this License in the various documents with a single copy + that is included in the collection, provided that you follow the + rules of this License for verbatim copying of each of the + documents in all other respects. + + You may extract a single document from such a collection, and + distribute it individually under this License, provided you insert + a copy of this License into the extracted document, and follow + this License in all other respects regarding verbatim copying of + that document. + + 7. AGGREGATION WITH INDEPENDENT WORKS + + A compilation of the Document or its derivatives with other + separate and independent documents or works, in or on a volume of + a storage or distribution medium, does not as a whole count as a + Modified Version of the Document, provided no compilation + copyright is claimed for the compilation. Such a compilation is + called an "aggregate", and this License does not apply to the + other self-contained works thus compiled with the Document, on + account of their being thus compiled, if they are not themselves + derivative works of the Document. + + If the Cover Text requirement of section 3 is applicable to these + copies of the Document, then if the Document is less than one + quarter of the entire aggregate, the Document's Cover Texts may be + placed on covers that surround only the Document within the + aggregate. Otherwise they must appear on covers around the whole + aggregate. + + 8. TRANSLATION + + Translation is considered a kind of modification, so you may + distribute translations of the Document under the terms of section + 4. Replacing Invariant Sections with translations requires special + permission from their copyright holders, but you may include + translations of some or all Invariant Sections in addition to the + original versions of these Invariant Sections. You may include a + translation of this License provided that you also include the + original English version of this License. In case of a + disagreement between the translation and the original English + version of this License, the original English version will prevail. + + 9. TERMINATION + + You may not copy, modify, sublicense, or distribute the Document + except as expressly provided for under this License. Any other + attempt to copy, modify, sublicense or distribute the Document is + void, and will automatically terminate your rights under this + License. However, parties who have received copies, or rights, + from you under this License will not have their licenses + terminated so long as such parties remain in full compliance. + + 10. FUTURE REVISIONS OF THIS LICENSE + + The Free Software Foundation may publish new, revised versions of + the GNU Free Documentation License from time to time. Such new + versions will be similar in spirit to the present version, but may + differ in detail to address new problems or concerns. See + `http://www.gnu.org/copyleft/'. + + Each version of the License is given a distinguishing version + number. If the Document specifies that a particular numbered + version of this License "or any later version" applies to it, you + have the option of following the terms and conditions either of + that specified version or of any later version that has been + published (not as a draft) by the Free Software Foundation. If + the Document does not specify a version number of this License, + you may choose any version ever published (not as a draft) by the + Free Software Foundation. + +ADDENDUM: How to use this License for your documents +---------------------------------------------------- + + To use this License in a document you have written, include a copy of +the License in the document and put the following copyright and license +notices just after the title page: + + Copyright (C) YEAR YOUR NAME. + Permission is granted to copy, distribute and/or modify this document + under the terms of the GNU Free Documentation License, Version 1.1 + or any later version published by the Free Software Foundation; + with the Invariant Sections being LIST THEIR TITLES, with the + Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. + A copy of the license is included in the section entitled ``GNU + Free Documentation License''. + + If you have no Invariant Sections, write "with no Invariant Sections" +instead of saying which ones are invariant.

Although the original ISO C90 standard already defined the +type `wchar_t', no functions operating on them were defined. + + The general design of the classification functions for wide +characters is more general. It allows extensions to the set of +available classifications, beyond those which are always available. +The POSIX standard specifies how extensions can be made, and this is +already implemented in the GNU C library implementation of the +`localedef' program. + + The character class functions are normally implemented with bitsets, +with a bitset per character. For a given character, the appropriate +bitset is read from a table and a test is performed as to whether a +certain bit is set. Which bit is tested for is determined by the class. + + For the wide character classification functions this is made visible. +There is a type classification type defined, a function to retrieve this +value for a given class, and a function to test whether a given +character is in this class, using the classification value. On top of +this the normal character classification functions as used for `char' +objects can be defined. + + - Data type: wctype_t + The `wctype_t' can hold a value which represents a character class. + The only defined way to generate such a value is by using the + `wctype' function. + + This type is defined in `wctype.h'. + + - Function: wctype_t wctype (const char *PROPERTY) + The `wctype' returns a value representing a class of wide + characters which is identified by the string PROPERTY. Beside + some standard properties each locale can define its own ones. In + case no property with the given name is known for the current + locale selected for the `LC_CTYPE' category, the function returns + zero. + + The properties known in every locale are: + + `"alnum"' `"alpha"' `"cntrl"' `"digit"' + `"graph"' `"lower"' `"print"' `"punct"' + `"space"' `"upper"' `"xdigit"' + + This function is declared in `wctype.h'. + + To test the membership of a character to one of the non-standard +classes the ISO C standard defines a completely new function. + + - Function: int iswctype (wint_t WC, wctype_t DESC) + This function returns a nonzero value if WC is in the character + class specified by DESC. DESC must previously be returned by a + successful call to `wctype'. + + This function is declared in `wctype.h'. + + To make it easier to use the commonly-used classification functions, +they are defined in the C library. There is no need to use `wctype' if +the property string is one of the known character classes. In some +situations it is desirable to construct the property strings, and then +it is important that `wctype' can also handle the standard classes. + + - Function: int iswalnum (wint_t WC) + This function returns a nonzero value if WC is an alphanumeric + character (a letter or number); in other words, if either + `iswalpha' or `iswdigit' is true of a character, then `iswalnum' + is also true. + + This function can be implemented using + + iswctype (wc, wctype ("alnum")) + + It is declared in `wctype.h'. + + - Function: int iswalpha (wint_t WC) + Returns true if WC is an alphabetic character (a letter). If + `iswlower' or `iswupper' is true of a character, then `iswalpha' + is also true. + + In some locales, there may be additional characters for which + `iswalpha' is true--letters which are neither upper case nor lower + case. But in the standard `"C"' locale, there are no such + additional characters. + + This function can be implemented using + + iswctype (wc, wctype ("alpha")) + + It is declared in `wctype.h'. + + - Function: int iswcntrl (wint_t WC) + Returns true if WC is a control character (that is, a character + that is not a printing character). + + This function can be implemented using + + iswctype (wc, wctype ("cntrl")) + + It is declared in `wctype.h'. + + - Function: int iswdigit (wint_t WC) + Returns true if WC is a digit (e.g., `0' through `9'). Please + note that this function does not only return a nonzero value for + _decimal_ digits, but for all kinds of digits. A consequence is + that code like the following will *not* work unconditionally for + wide characters: + + n = 0; + while (iswdigit (*wc)) + { + n *= 10; + n += *wc++ - L'0'; + } + + This function can be implemented using + + iswctype (wc, wctype ("digit")) + + It is declared in `wctype.h'. + + - Function: int iswgraph (wint_t WC) + Returns true if WC is a graphic character; that is, a character + that has a glyph associated with it. The whitespace characters + are not considered graphic. + + This function can be implemented using + + iswctype (wc, wctype ("graph")) + + It is declared in `wctype.h'. + + - Function: int iswlower (wint_t WC) + Returns true if WC is a lower-case letter. The letter need not be + from the Latin alphabet, any alphabet representable is valid. + + This function can be implemented using + + iswctype (wc, wctype ("lower")) + + It is declared in `wctype.h'. + + - Function: int iswprint (wint_t WC) + Returns true if WC is a printing character. Printing characters + include all the graphic characters, plus the space (` ') character. + + This function can be implemented using + + iswctype (wc, wctype ("print")) + + It is declared in `wctype.h'. + + - Function: int iswpunct (wint_t WC) + Returns true if WC is a punctuation character. This means any + printing character that is not alphanumeric or a space character. + + This function can be implemented using + + iswctype (wc, wctype ("punct")) + + It is declared in `wctype.h'. + + - Function: int iswspace (wint_t WC) + Returns true if WC is a "whitespace" character. In the standard + `"C"' locale, `iswspace' returns true for only the standard + whitespace characters: + + `L' '' + space + + `L'\f'' + formfeed + + `L'\n'' + newline + + `L'\r'' + carriage return + + `L'\t'' + horizontal tab + + `L'\v'' + vertical tab + + This function can be implemented using + + iswctype (wc, wctype ("space")) + + It is declared in `wctype.h'. + + - Function: int iswupper (wint_t WC) + Returns true if WC is an upper-case letter. The letter need not be + from the Latin alphabet, any alphabet representable is valid. + + This function can be implemented using + + iswctype (wc, wctype ("upper")) + + It is declared in `wctype.h'. + + - Function: int iswxdigit (wint_t WC) + Returns true if WC is a hexadecimal digit. Hexadecimal digits + include the normal decimal digits `0' through `9' and the letters + `A' through `F' and `a' through `f'. + + This function can be implemented using + + iswctype (wc, wctype ("xdigit")) + + It is declared in `wctype.h'. + + The GNU C library also provides a function which is not defined in +the ISO C standard but which is available as a version for single byte +characters as well. + + - Function: int iswblank (wint_t WC) + Returns true if WC is a blank character; that is, a space or a tab. + This function is a GNU extension. It is declared in `wchar.h'. + + +File: libc.info, Node: Using Wide Char Classes, Next: Wide Character Case Conversion, Prev: Classification of Wide Characters, Up: Character Handling + +Notes on using the wide character classes +========================================= + + The first note is probably not astonishing but still occasionally a +cause of problems. The `iswXXX' functions can be implemented using +macros and in fact, the GNU C library does this.

The correct solution to this +problem is to write the code as follows: + + int + is_in_class (int c, const char *class) + { + wctype_t desc = wctype (class); + return desc ? iswctype (btowc (c), desc) : 0; + } + + *Note Converting a Character::, for more information on `btowc'. +Note that this change probably does not improve the performance of the +program a lot since the `wctype' function still has to make the string +comparisons.

DESC must be obtained by a successful call to `wctrans'. + + This function is declared in `wctype.h'. + + For the generally available mappings, the ISO C standard defines +convenient shortcuts so that it is not necessary to call `wctrans' for +them. + + - Function: wint_t towlower (wint_t WC) + If WC is an upper-case letter, `towlower' returns the corresponding + lower-case letter. If WC is not an upper-case letter, WC is + returned unchanged. + + `towlower' can be implemented using + + towctrans (wc, wctrans ("tolower")) + + This function is declared in `wctype.h'. + + - Function: wint_t towupper (wint_t WC) + If WC is a lower-case letter, `towupper' returns the corresponding + upper-case letter.

That is, the first character from - WFROM overwrites the null character marking the end of WTO. - - An equivalent definition for `wcscat' would be: - - wchar_t * - wcscat (wchar_t *wto, const wchar_t *wfrom) - { - wcscpy (wto + wcslen (wto), wfrom); - return wto; - } - - This function has undefined results if the strings overlap. - - Programmers using the `strcat' or `wcscat' function (or the -following `strncat' or `wcsncar' functions for that matter) can easily -be recognized as lazy and reckless. In almost all situations the -lengths of the participating strings are known (it better should be -since how can one otherwise ensure the allocated size of the buffer is -sufficient?) Or at least, one could know them if one keeps track of the -results of the various function calls. But then it is very inefficient -to use `strcat'/`wcscat'. A lot of time is wasted finding the end of -the destination string so that the actual copying can start. This is a -common example: - - /* This function concatenates arbitrarily many strings. The last - parameter must be `NULL'. */ - char * - concat (const char *str, ...) - { - va_list ap, ap2; - size_t total = 1; - const char *s; - char *result; - - va_start (ap, str); - /* Actually `va_copy', but this is the name more gcc versions - understand. */ - __va_copy (ap2, ap); - - /* Determine how much space we need. */ - for (s = str; s != NULL; s = va_arg (ap, const char *)) - total += strlen (s); - - va_end (ap); - - result = (char *) malloc (total); - if (result != NULL) - { - result[0] = '\0'; - - /* Copy the strings. */ - for (s = str; s != NULL; s = va_arg (ap2, const char *)) - strcat (result, s); - } - - va_end (ap2); - - return result; - } - - This looks quite simple, especially the second loop where the strings -are actually copied. But these innocent lines hide a major performance -penalty. Just imagine that ten strings of 100 bytes each have to be -concatenated. For the second string we search the already stored 100 -bytes for the end of the string so that we can append the next string. -For all strings in total the comparisons necessary to find the end of -the intermediate results sums up to 5500! If we combine the copying -with the search for the allocation we can write this function more -efficient: - - char * - concat (const char *str, ...) - { - va_list ap; - size_t allocated = 100; - char *result = (char *) malloc (allocated); - char *wp; - - if (allocated != NULL) - { - char *newp; - - va_start (ap, atr); - - wp = result; - for (s = str; s != NULL; s = va_arg (ap, const char *)) - { - size_t len = strlen (s); - - /* Resize the allocated memory if necessary. */ - if (wp + len + 1 > result + allocated) - { - allocated = (allocated + len) * 2; - newp = (char *) realloc (result, allocated); - if (newp == NULL) - { - free (result); - return NULL; - } - wp = newp + (wp - result); - result = newp; - } - - wp = mempcpy (wp, s, len); - } - - /* Terminate the result string. */ - *wp++ = '\0'; - - /* Resize memory to the optimal size. */ - newp = realloc (result, wp - result); - if (newp != NULL) - result = newp; - - va_end (ap); - } - - return result; - } - - With a bit more knowledge about the input strings one could fine-tune -the memory allocation. The difference we are pointing to here is that -we don't use `strcat' anymore. We always keep track of the length of -the current intermediate result so we can safe us the search for the -end of the string and use `mempcpy'. Please note that we also don't -use `stpcpy' which might seem more natural since we handle with -strings. But this is not necessary since we already know the length of -the string and therefore can use the faster memory copying function. -The example would work for wide characters the same way. - - Whenever a programmer feels the need to use `strcat' she or he -should think twice and look through the program whether the code cannot -be rewritten to take advantage of already calculated results. Again: it -is almost always unnecessary to use `strcat'. - - - Function: char * strncat (char *restrict TO, const char *restrict - FROM, size_t SIZE) - This function is like `strcat' except that not more than SIZE - characters from FROM are appended to the end of TO. A single null - character is also always appended to TO, so the total allocated - size of TO must be at least `SIZE + 1' bytes longer than its - initial length. - - The `strncat' function could be implemented like this: - - char * - strncat (char *to, const char *from, size_t size) - { - to[strlen (to) + size] = '\0'; - strncpy (to + strlen (to), from, size); - return to; - } - - The behavior of `strncat' is undefined if the strings overlap. - - - Function: wchar_t * wcsncat (wchar_t *restrict WTO, const wchar_t - *restrict WFROM, size_t SIZE) - This function is like `wcscat' except that not more than SIZE - characters from FROM are appended to the end of TO. A single null - character is also always appended to TO, so the total allocated - size of TO must be at least `SIZE + 1' bytes longer than its - initial length. - - The `wcsncat' function could be implemented like this: - - wchar_t * - wcsncat (wchar_t *restrict wto, const wchar_t *restrict wfrom, - size_t size) - { - wto[wcslen (to) + size] = L'\0'; - wcsncpy (wto + wcslen (wto), wfrom, size); - return wto; - } - - The behavior of `wcsncat' is undefined if the strings overlap. - - Here is an example showing the use of `strncpy' and `strncat' (the -wide character version is equivalent). Notice how, in the call to -`strncat', the SIZE parameter is computed to avoid overflowing the -character array `buffer'. - - #include - #include - - #define SIZE 10 - - static char buffer[SIZE]; - - main () - { - strncpy (buffer, "hello", SIZE); - puts (buffer); - strncat (buffer, ", world", SIZE - strlen (buffer) - 1); - puts (buffer); - } - -The output produced by this program looks like: - - hello - hello, wo - - - Function: void bcopy (const void *FROM, void *TO, size_t SIZE) - This is a partially obsolete alternative for `memmove', derived - from BSD.

As well as checking for equality, -these functions can also be used as the ordering functions for sorting -operations. *Note Searching and Sorting::, for an example of this. - - Unlike most comparison operations in C, the string comparison -functions return a nonzero value if the strings are _not_ equivalent -rather than if they are. The sign of the value indicates the relative -ordering of the first characters in the strings that are not -equivalent: a negative value indicates that the first string is "less" -than the second, while a positive value indicates that the first string -is "greater". - - The most common use of these functions is to check only for equality. -This is canonically done with an expression like `! strcmp (s1, s2)'. - - All of these functions are declared in the header file `string.h'. - - - Function: int memcmp (const void *A1, const void *A2, size_t SIZE) - The function `memcmp' compares the SIZE bytes of memory beginning - at A1 against the SIZE bytes of memory beginning at A2. The value - returned has the same sign as the difference between the first - differing pair of bytes (interpreted as `unsigned char' objects, - then promoted to `int'). - - If the contents of the two blocks are equal, `memcmp' returns `0'. - - - Function: int wmemcmp (const wchar_t *A1, const wchar_t *A2, size_t - SIZE) - The function `wmemcmp' compares the SIZE wide characters beginning - at A1 against the SIZE wide characters beginning at A2. The value - returned is smaller than or larger than zero depending on whether - the first differing wide character is A1 is smaller or larger than - the corresponding character in A2. - - If the contents of the two blocks are equal, `wmemcmp' returns `0'. - - On arbitrary arrays, the `memcmp' function is mostly useful for -testing equality. It usually isn't meaningful to do byte-wise ordering -comparisons on arrays of things other than bytes. For example, a -byte-wise comparison on the bytes that make up floating-point numbers -isn't likely to tell you anything about the relationship between the -values of the floating-point numbers. - - `wmemcmp' is really only useful to compare arrays of type `wchar_t' -since the function looks at `sizeof (wchar_t)' bytes at a time and this -number of bytes is system dependent. - - You should also be careful about using `memcmp' to compare objects -that can contain "holes", such as the padding inserted into structure -objects to enforce alignment requirements, extra space at the end of -unions, and extra characters at the ends of strings whose length is less -than their allocated size. The contents of these "holes" are -indeterminate and may cause strange behavior when performing byte-wise -comparisons. For more predictable results, perform an explicit -component-wise comparison. - - For example, given a structure type definition like: - - struct foo - { - unsigned char tag; - union - { - double f; - long i; - char *p; - } value; - }; - -you are better off writing a specialized comparison function to compare -`struct foo' objects instead of comparing them with `memcmp'. - - - Function: int strcmp (const char *S1, const char *S2) - The `strcmp' function compares the string S1 against S2, returning - a value that has the same sign as the difference between the first - differing pair of characters (interpreted as `unsigned char' - objects, then promoted to `int'). - - If the two strings are equal, `strcmp' returns `0'. - - A consequence of the ordering used by `strcmp' is that if S1 is an - initial substring of S2, then S1 is considered to be "less than" - S2. - - `strcmp' does not take sorting conventions of the language the - strings are written in into account. To get that one has to use - `strcoll'. - - - Function: int wcscmp (const wchar_t *WS1, const wchar_t *WS2) - The `wcscmp' function compares the wide character string WS1 - against WS2. The value returned is smaller than or larger than - zero depending on whether the first differing wide character is - WS1 is smaller or larger than the corresponding character in WS2. - - If the two strings are equal, `wcscmp' returns `0'. - - A consequence of the ordering used by `wcscmp' is that if WS1 is - an initial substring of WS2, then WS1 is considered to be "less - than" WS2. - - `wcscmp' does not take sorting conventions of the language the - strings are written in into account. To get that one has to use - `wcscoll'. - - - Function: int strcasecmp (const char *S1, const char *S2) - This function is like `strcmp', except that differences in case are - ignored. How uppercase and lowercase characters are related is - determined by the currently selected locale. In the standard `"C"' - locale the characters A" and a" do not match but in a locale which - regards these characters as parts of the alphabet they do match. - - `strcasecmp' is derived from BSD. - - - Function: int wcscasecmp (const wchar_t *WS1, const wchar_T *WS2) - This function is like `wcscmp', except that differences in case are - ignored. How uppercase and lowercase characters are related is - determined by the currently selected locale. In the standard `"C"' - locale the characters A" and a" do not match but in a locale which - regards these characters as parts of the alphabet they do match. - - `wcscasecmp' is a GNU extension. - - - Function: int strncmp (const char *S1, const char *S2, size_t SIZE) - This function is the similar to `strcmp', except that no more than - SIZE wide characters are compared. In other words, if the two - strings are the same in their first SIZE wide characters, the - return value is zero. - - - Function: int wcsncmp (const wchar_t *WS1, const wchar_t *WS2, - size_t SIZE) - This function is the similar to `wcscmp', except that no more than - SIZE wide characters are compared. In other words, if the two - strings are the same in their first SIZE wide characters, the - return value is zero. - - - Function: int strncasecmp (const char *S1, const char *S2, size_t N) - This function is like `strncmp', except that differences in case - are ignored. Like `strcasecmp', it is locale dependent how - uppercase and lowercase characters are related. - - `strncasecmp' is a GNU extension. - - - Function: int wcsncasecmp (const wchar_t *WS1, const wchar_t *S2, - size_t N) - This function is like `wcsncmp', except that differences in case - are ignored. Like `wcscasecmp', it is locale dependent how - uppercase and lowercase characters are related. - - `wcsncasecmp' is a GNU extension. - - Here are some examples showing the use of `strcmp' and `strncmp' -(equivalent examples can be constructed for the wide character -functions). These examples assume the use of the ASCII character set. -(If some other character set--say, EBCDIC--is used instead, then the -glyphs are associated with different numeric codes, and the return -values and ordering may differ.) - - strcmp ("hello", "hello") - => 0 /* These two strings are the same. */ - strcmp ("hello", "Hello") - => 32 /* Comparisons are case-sensitive. */ - strcmp ("hello", "world") - => -15 /* The character `'h'' comes before `'w''. */ - strcmp ("hello", "hello, world") - => -44 /* Comparing a null character against a comma. */ - strncmp ("hello", "hello, world", 5) - => 0 /* The initial 5 characters are the same. */ - strncmp ("hello, world", "hello, stupid world!!!", 5) - => 0 /* The initial 5 characters are the same. */ - - - Function: int strverscmp (const char *S1, const char *S2) - The `strverscmp' function compares the string S1 against S2, - considering them as holding indices/version numbers. Return value - follows the same conventions as found in the `strverscmp' - function. In fact, if S1 and S2 contain no digits, `strverscmp' - behaves like `strcmp'. - - Basically, we compare strings normally (character by character), - until we find a digit in each string - then we enter a special - comparison mode, where each sequence of digits is taken as a - whole. If we reach the end of these two parts without noticing a - difference, we return to the standard comparison mode. There are - two types of numeric parts: "integral" and "fractional" (those - begin with a '0'). The types of the numeric parts affect the way - we sort them: - - * integral/integral: we compare values as you would expect. - - * fractional/integral: the fractional part is less than the - integral one. Again, no surprise. - - * fractional/fractional: the things become a bit more complex. - If the common prefix contains only leading zeroes, the - longest part is less than the other one; else the comparison - behaves normally. - - strverscmp ("no digit", "no digit") - => 0 /* same behavior as strcmp. */ - strverscmp ("item#99", "item#100") - => <0 /* same prefix, but 99 < 100. */ - strverscmp ("alpha1", "alpha001") - => >0 /* fractional part inferior to integral one. */ - strverscmp ("part1_f012", "part1_f01") - => >0 /* two fractional parts. */ - strverscmp ("foo.009", "foo.0") - => <0 /* idem, but with leading zeroes only. */ - - This function is especially useful when dealing with filename - sorting, because filenames frequently hold indices/version numbers. - - `strverscmp' is a GNU extension. - - - Function: int bcmp (const void *A1, const void *A2, size_t SIZE) - This is an obsolete alias for `memcmp', derived from BSD. diff -durpN glibc-2.2.4/manual/libc.info-60 glibc-2.2.5/manual/libc.info-60 --- glibc-2.2.4/manual/libc.info-60 Mon Aug 13 15:03:42 2001 +++ glibc-2.2.5/manual/libc.info-60 Sun Jan 20 19:28:42 2002 @@ -1,4 +1,4 @@ -This is libc.info, produced by makeinfo version 4.0c from libc.texinfo. +This is libc.info, produced by makeinfo version 4.0 from libc.texinfo.

Copies published by the Free funds for GNU development.  +File: libc.info, Node: Copying and Concatenation, Next: String/Array Comparison, Prev: String Length, Up: String and Array Utilities + +Copying and Concatenation +========================= + + You can use the functions described in this section to copy the +contents of strings and arrays, or to append the contents of one string +to another. The `str' and `mem' functions are declared in the header +file `string.h' while the `wstr' and `wmem' functions are declared in +the file `wchar.h'. + + A helpful way to remember the ordering of the arguments to the +functions in this section is that it corresponds to an assignment +expression, with the destination array specified to the left of the +source array. All of these functions return the address of the +destination array. + + Most of these functions do not work properly if the source and +destination arrays overlap. For example, if the beginning of the +destination array overlaps the end of the source array, the original +contents of that part of the source array may get overwritten before it +is copied. Even worse, in the case of the string functions, the null +character marking the end of the string may be lost, and the copy +function might get stuck in a loop trashing all the memory allocated to +your program. + + All functions that have problems copying between overlapping arrays +are explicitly identified in this manual. In addition to functions in +this section, there are a few others like `sprintf' (*note Formatted +Output Functions::) and `scanf' (*note Formatted Input Functions::). + + - Function: void * memcpy (void *restrict TO, const void *restrict + FROM, size_t SIZE) + The `memcpy' function copies SIZE bytes from the object beginning + at FROM into the object beginning at TO. The behavior of this + function is undefined if the two arrays TO and FROM overlap; use + `memmove' instead if overlapping is possible. + + The value returned by `memcpy' is the value of TO. + + Here is an example of how you might use `memcpy' to copy the + contents of an array: + + struct foo *oldarray, *newarray; + int arraysize; + ... + memcpy (new, old, arraysize * sizeof (struct foo)); + + - Function: wchar_t * wmemcpy (wchar_t *restrict WTO, const wchar_t + *restruct WFROM, size_t SIZE) + The `wmemcpy' function copies SIZE wide characters from the object + beginning at WFROM into the object beginning at WTO. The behavior + of this function is undefined if the two arrays WTO and WFROM + overlap; use `wmemmove' instead if overlapping is possible. + + The following is a possible implementation of `wmemcpy' but there + are more optimizations possible. + + wchar_t * + wmemcpy (wchar_t *restrict wto, const wchar_t *restrict wfrom, + size_t size) + { + return (wchar_t *) memcpy (wto, wfrom, size * sizeof (wchar_t)); + } + + The value returned by `wmemcpy' is the value of WTO. + + This function was introduced in Amendment 1 to ISO C90. + + - Function: void * mempcpy (void *restrict TO, const void *restrict + FROM, size_t SIZE) + The `mempcpy' function is nearly identical to the `memcpy' + function.

In almost all situations the +lengths of the participating strings are known (it better should be +since how can one otherwise ensure the allocated size of the buffer is +sufficient?) Or at least, one could know them if one keeps track of the +results of the various function calls. But then it is very inefficient +to use `strcat'/`wcscat'. A lot of time is wasted finding the end of +the destination string so that the actual copying can start. This is a +common example: + + /* This function concatenates arbitrarily many strings. The last + parameter must be `NULL'. */ + char * + concat (const char *str, ...) + { + va_list ap, ap2; + size_t total = 1; + const char *s; + char *result; + + va_start (ap, str); + /* Actually `va_copy', but this is the name more gcc versions + understand. */ + __va_copy (ap2, ap); + + /* Determine how much space we need. */ + for (s = str; s != NULL; s = va_arg (ap, const char *)) + total += strlen (s); + + va_end (ap); + + result = (char *) malloc (total); + if (result != NULL) + { + result[0] = '\0'; + + /* Copy the strings. */ + for (s = str; s != NULL; s = va_arg (ap2, const char *)) + strcat (result, s); + } + + va_end (ap2); + + return result; + } + + This looks quite simple, especially the second loop where the strings +are actually copied. But these innocent lines hide a major performance +penalty. Just imagine that ten strings of 100 bytes each have to be +concatenated. For the second string we search the already stored 100 +bytes for the end of the string so that we can append the next string. +For all strings in total the comparisons necessary to find the end of +the intermediate results sums up to 5500! If we combine the copying +with the search for the allocation we can write this function more +efficient: + + char * + concat (const char *str, ...) + { + va_list ap; + size_t allocated = 100; + char *result = (char *) malloc (allocated); + char *wp; + + if (allocated != NULL) + { + char *newp; + + va_start (ap, atr); + + wp = result; + for (s = str; s != NULL; s = va_arg (ap, const char *)) + { + size_t len = strlen (s); + + /* Resize the allocated memory if necessary. */ + if (wp + len + 1 > result + allocated) + { + allocated = (allocated + len) * 2; + newp = (char *) realloc (result, allocated); + if (newp == NULL) + { + free (result); + return NULL; + } + wp = newp + (wp - result); + result = newp; + } + + wp = mempcpy (wp, s, len); + } + + /* Terminate the result string. */ + *wp++ = '\0'; + + /* Resize memory to the optimal size. */ + newp = realloc (result, wp - result); + if (newp != NULL) + result = newp; + + va_end (ap); + } + + return result; + } + + With a bit more knowledge about the input strings one could fine-tune +the memory allocation. The difference we are pointing to here is that +we don't use `strcat' anymore. We always keep track of the length of +the current intermediate result so we can safe us the search for the +end of the string and use `mempcpy'. Please note that we also don't +use `stpcpy' which might seem more natural since we handle with +strings. But this is not necessary since we already know the length of +the string and therefore can use the faster memory copying function. +The example would work for wide characters the same way. + + Whenever a programmer feels the need to use `strcat' she or he +should think twice and look through the program whether the code cannot +be rewritten to take advantage of already calculated results. Again: it +is almost always unnecessary to use `strcat'. + + - Function: char * strncat (char *restrict TO, const char *restrict + FROM, size_t SIZE) + This function is like `strcat' except that not more than SIZE + characters from FROM are appended to the end of TO.

As well as checking for equality, +these functions can also be used as the ordering functions for sorting +operations. *Note Searching and Sorting::, for an example of this. + + Unlike most comparison operations in C, the string comparison +functions return a nonzero value if the strings are _not_ equivalent +rather than if they are. The sign of the value indicates the relative +ordering of the first characters in the strings that are not +equivalent: a negative value indicates that the first string is "less" +than the second, while a positive value indicates that the first string +is "greater". + + The most common use of these functions is to check only for equality. +This is canonically done with an expression like `! strcmp (s1, s2)'. + + All of these functions are declared in the header file `string.h'. + + - Function: int memcmp (const void *A1, const void *A2, size_t SIZE) + The function `memcmp' compares the SIZE bytes of memory beginning + at A1 against the SIZE bytes of memory beginning at A2. The value + returned has the same sign as the difference between the first + differing pair of bytes (interpreted as `unsigned char' objects, + then promoted to `int'). + + If the contents of the two blocks are equal, `memcmp' returns `0'. + + - Function: int wmemcmp (const wchar_t *A1, const wchar_t *A2, size_t + SIZE) + The function `wmemcmp' compares the SIZE wide characters beginning + at A1 against the SIZE wide characters beginning at A2. The value + returned is smaller than or larger than zero depending on whether + the first differing wide character is A1 is smaller or larger than + the corresponding character in A2. + + If the contents of the two blocks are equal, `wmemcmp' returns `0'. + + On arbitrary arrays, the `memcmp' function is mostly useful for +testing equality. It usually isn't meaningful to do byte-wise ordering +comparisons on arrays of things other than bytes. For example, a +byte-wise comparison on the bytes that make up floating-point numbers +isn't likely to tell you anything about the relationship between the +values of the floating-point numbers. + + `wmemcmp' is really only useful to compare arrays of type `wchar_t' +since the function looks at `sizeof (wchar_t)' bytes at a time and this +number of bytes is system dependent. + + You should also be careful about using `memcmp' to compare objects +that can contain "holes", such as the padding inserted into structure +objects to enforce alignment requirements, extra space at the end of +unions, and extra characters at the ends of strings whose length is less +than their allocated size. The contents of these "holes" are +indeterminate and may cause strange behavior when performing byte-wise +comparisons. For more predictable results, perform an explicit +component-wise comparison. + + For example, given a structure type definition like: + + struct foo + { + unsigned char tag; + union + { + double f; + long i; + char *p; + } value; + }; + +you are better off writing a specialized comparison function to compare +`struct foo' objects instead of comparing them with `memcmp'. + + - Function: int strcmp (const char *S1, const char *S2) + The `strcmp' function compares the string S1 against S2, returning + a value that has the same sign as the difference between the first + differing pair of characters (interpreted as `unsigned char' + objects, then promoted to `int'). + + If the two strings are equal, `strcmp' returns `0'. + + A consequence of the ordering used by `strcmp' is that if S1 is an + initial substring of S2, then S1 is considered to be "less than" + S2. + + `strcmp' does not take sorting conventions of the language the + strings are written in into account.

The return value is a pointer to the located wide - character, or a null pointer if no match was found. - - - Function: void * rawmemchr (const void *BLOCK, int C) - Often the `memchr' function is used with the knowledge that the - byte C is available in the memory block specified by the - parameters. But this means that the SIZE parameter is not really - needed and that the tests performed with it at runtime (to check - whether the end of the block is reached) are not needed. - - The `rawmemchr' function exists for just this situation which is - surprisingly frequent. The interface is similar to `memchr' except - that the SIZE parameter is missing. The function will look beyond - the end of the block pointed to by BLOCK in case the programmer - made an error in assuming that the byte C is present in the block. - In this case the result is unspecified. Otherwise the return - value is a pointer to the located byte. - - This function is of special interest when looking for the end of a - string. Since all strings are terminated by a null byte a call - like - - rawmemchr (str, '\0') - - will never go beyond the end of the string. - - This function is a GNU extension. - - - Function: void * memrchr (const void *BLOCK, int C, size_t SIZE) - The function `memrchr' is like `memchr', except that it searches - backwards from the end of the block defined by BLOCK and SIZE - (instead of forwards from the front). - - - Function: char * strchr (const char *STRING, int C) - The `strchr' function finds the first occurrence of the character - C (converted to a `char') in the null-terminated string beginning - at STRING. The return value is a pointer to the located - character, or a null pointer if no match was found. - - For example, - strchr ("hello, world", 'l') - => "llo, world" - strchr ("hello, world", '?') - => NULL - - The terminating null character is considered to be part of the - string, so you can use this function get a pointer to the end of a - string by specifying a null character as the value of the C - argument. It would be better (but less portable) to use - `strchrnul' in this case, though. - - - Function: wchar_t * wcschr (const wchar_t *WSTRING, int WC) - The `wcschr' function finds the first occurrence of the wide - character WC in the null-terminated wide character string - beginning at WSTRING. The return value is a pointer to the - located wide character, or a null pointer if no match was found. - - The terminating null character is considered to be part of the wide - character string, so you can use this function get a pointer to - the end of a wide character string by specifying a null wude - character as the value of the WC argument. It would be better - (but less portable) to use `wcschrnul' in this case, though. - - - Function: char * strchrnul (const char *STRING, int C) - `strchrnul' is the same as `strchr' except that if it does not - find the character, it returns a pointer to string's terminating - null character rather than a null pointer. - - This function is a GNU extension. - - - Function: wchar_t * wcschrnul (const wchar_t *WSTRING, wchar_t WC) - `wcschrnul' is the same as `wcschr' except that if it does not - find the wide character, it returns a pointer to wide character - string's terminating null wide character rather than a null - pointer. - - This function is a GNU extension. - - One useful, but unusual, use of the `strchr' function is when one -wants to have a pointer pointing to the NUL byte terminating a string. -This is often written in this way: - - s += strlen (s); - -This is almost optimal but the addition operation duplicated a bit of -the work already done in the `strlen' function. A better solution is -this: - - s = strchr (s, '\0'); - - There is no restriction on the second parameter of `strchr' so it -could very well also be the NUL character. Those readers thinking very -hard about this might now point out that the `strchr' function is more -expensive than the `strlen' function since we have two abort criteria. -This is right. But in the GNU C library the implementation of `strchr' -is optimized in a special way so that `strchr' actually is faster. - - - Function: char * strrchr (const char *STRING, int C) - The function `strrchr' is like `strchr', except that it searches - backwards from the end of the string STRING (instead of forwards - from the front). - - For example, - strrchr ("hello, world", 'l') - => "ld" - - - Function: wchar_t * wcsrchr (const wchar_t *WSTRING, wchar_t C) - The function `wcsrchr' is like `wcschr', except that it searches - backwards from the end of the string WSTRING (instead of forwards - from the front). - - - Function: char * strstr (const char *HAYSTACK, const char *NEEDLE) - This is like `strchr', except that it searches HAYSTACK for a - substring NEEDLE rather than just a single character. It returns - a pointer into the string HAYSTACK that is the first character of - the substring, or a null pointer if no match was found. If NEEDLE - is an empty string, the function returns HAYSTACK. - - For example, - strstr ("hello, world", "l") - => "llo, world" - strstr ("hello, world", "wo") - => "world" - - - Function: wchar_t * wcsstr (const wchar_t *HAYSTACK, const wchar_t - *NEEDLE) - This is like `wcschr', except that it searches HAYSTACK for a - substring NEEDLE rather than just a single wide character. It - returns a pointer into the string HAYSTACK that is the first wide - character of the substring, or a null pointer if no match was - found. If NEEDLE is an empty string, the function returns - HAYSTACK. - - - Function: wchar_t * wcswcs (const wchar_t *HAYSTACK, const wchar_t - *NEEDLE) - `wcsstr' is an depricated alias for `wcsstr'. This is the name - originally used in the X/Open Portability Guide before the - Amendment 1 to ISO C90 was published. - - - Function: char * strcasestr (const char *HAYSTACK, const char - *NEEDLE) - This is like `strstr', except that it ignores case in searching for - the substring. Like `strcasecmp', it is locale dependent how - uppercase and lowercase characters are related. - - For example, - strstr ("hello, world", "L") - => "llo, world" - strstr ("hello, World", "wo") - => "World" - - - Function: void * memmem (const void *HAYSTACK, size_t HAYSTACK-LEN, - const void *NEEDLE, size_t NEEDLE-LEN) - This is like `strstr', but NEEDLE and HAYSTACK are byte arrays - rather than null-terminated strings. NEEDLE-LEN is the length of - NEEDLE and HAYSTACK-LEN is the length of HAYSTACK. - - This function is a GNU extension. - - - Function: size_t strspn (const char *STRING, const char *SKIPSET) - The `strspn' ("string span") function returns the length of the - initial substring of STRING that consists entirely of characters - that are members of the set specified by the string SKIPSET. The - order of the characters in SKIPSET is not important. - - For example, - strspn ("hello, world", "abcdefghijklmnopqrstuvwxyz") - => 5 - - Note that "character" is here used in the sense of byte. In a - string using a multibyte character encoding (abstract) character - consisting of more than one byte are not treated as an entity. - Each byte is treated separately. The function is not - locale-dependent. - - - Function: size_t wcsspn (const wchar_t *WSTRING, const wchar_t - *SKIPSET) - The `wcsspn' ("wide character string span") function returns the - length of the initial substring of WSTRING that consists entirely - of wide characters that are members of the set specified by the - string SKIPSET. The order of the wide characters in SKIPSET is not - important. - - - Function: size_t strcspn (const char *STRING, const char *STOPSET) - The `strcspn' ("string complement span") function returns the - length of the initial substring of STRING that consists entirely - of characters that are _not_ members of the set specified by the - string STOPSET. (In other words, it returns the offset of the - first character in STRING that is a member of the set STOPSET.) - - For example, - strcspn ("hello, world", " \t\n,.;!?") - => 5 - - Note that "character" is here used in the sense of byte. In a - string using a multibyte character encoding (abstract) character - consisting of more than one byte are not treated as an entity. - Each byte is treated separately. The function is not - locale-dependent. - - - Function: size_t wcscspn (const wchar_t *WSTRING, const wchar_t - *STOPSET) - The `wcscspn' ("wide character string complement span") function - returns the length of the initial substring of WSTRING that - consists entirely of wide characters that are _not_ members of the - set specified by the string STOPSET. (In other words, it returns - the offset of the first character in STRING that is a member of - the set STOPSET.) - - - Function: char * strpbrk (const char *STRING, const char *STOPSET) - The `strpbrk' ("string pointer break") function is related to - `strcspn', except that it returns a pointer to the first character - in STRING that is a member of the set STOPSET instead of the - length of the initial substring. It returns a null pointer if no - such character from STOPSET is found. - - For example, - - strpbrk ("hello, world", " \t\n,.;!?") - => ", world" - - Note that "character" is here used in the sense of byte. In a - string using a multibyte character encoding (abstract) character - consisting of more than one byte are not treated as an entity. - Each byte is treated separately. The function is not - locale-dependent. - - - Function: wchar_t * wcspbrk (const wchar_t *WSTRING, const wchar_t - *STOPSET) - The `wcspbrk' ("wide character string pointer break") function is - related to `wcscspn', except that it returns a pointer to the first - wide character in WSTRING that is a member of the set STOPSET - instead of the length of the initial substring. It returns a null - pointer if no such character from STOPSET is found. - -Compatibility String Search Functions -------------------------------------- - - - Function: char * index (const char *STRING, int C) - `index' is another name for `strchr'; they are exactly the same. - New code should always use `strchr' since this name is defined in - ISO C while `index' is a BSD invention which never was available - on System V derived systems. - - - Function: char * rindex (const char *STRING, int C) - `rindex' is another name for `strrchr'; they are exactly the same. - New code should always use `strrchr' since this name is defined in - ISO C while `rindex' is a BSD invention which never was available - on System V derived systems. - - -File: libc.info, Node: Finding Tokens in a String, Next: strfry, Prev: Search Functions, Up: String and Array Utilities - -Finding Tokens in a String -========================== - - It's fairly common for programs to have a need to do some simple -kinds of lexical analysis and parsing, such as splitting a command -string up into tokens. You can do this with the `strtok' function, -declared in the header file `string.h'. - - - Function: char * strtok (char *restrict NEWSTRING, const char - *restrict DELIMITERS) - A string can be split into tokens by making a series of calls to - the function `strtok'. - - The string to be split up is passed as the NEWSTRING argument on - the first call only. The `strtok' function uses this to set up - some internal state information. Subsequent calls to get - additional tokens from the same string are indicated by passing a - null pointer as the NEWSTRING argument. Calling `strtok' with - another non-null NEWSTRING argument reinitializes the state - information. It is guaranteed that no other library function ever - calls `strtok' behind your back (which would mess up this internal - state information). - - The DELIMITERS argument is a string that specifies a set of - delimiters that may surround the token being extracted. All the - initial characters that are members of this set are discarded. - The first character that is _not_ a member of this set of - delimiters marks the beginning of the next token.

The function is not - locale-dependent. - - *Warning:* Since `strtok' and `wcstok' alter the string they is -parsing, you should always copy the string to a temporary buffer before -parsing it with `strtok'/`wcstok' (*note Copying and Concatenation::). -If you allow `strtok' or `wcstok' to modify a string that came from -another part of your program, you are asking for trouble; that string -might be used for other purposes after `strtok' or `wcstok' has -modified it, and it would not have the expected value. - - The string that you are operating on might even be a constant. Then -when `strtok' or `wcstok' tries to modify it, your program will get a -fatal signal for writing in read-only memory. *Note Program Error -Signals::. Even if the operation of `strtok' or `wcstok' would not -require a modification of the string (e.g., if there is exactly one -token) the string can (and in the GNU libc case will) be modified. - - This is a special case of a general principle: if a part of a program -does not have as its purpose the modification of a certain data -structure, then it is error-prone to modify the data structure -temporarily. - - The functions `strtok' and `wcstok' are not reentrant. *Note -Nonreentrancy::, for a discussion of where and why reentrancy is -important. - - Here is a simple example showing the use of `strtok'. - - #include - #include - - ... - - const char string[] = "words separated by spaces -- and, punctuation!"; - const char delimiters[] = " .,;:!-"; - char *token, *cp; - - ... - - cp = strdupa (string); /* Make writable copy. */ - token = strtok (cp, delimiters); /* token => "words" */ - token = strtok (NULL, delimiters); /* token => "separated" */ - token = strtok (NULL, delimiters); /* token => "by" */ - token = strtok (NULL, delimiters); /* token => "spaces" */ - token = strtok (NULL, delimiters); /* token => "and" */ - token = strtok (NULL, delimiters); /* token => "punctuation" */ - token = strtok (NULL, delimiters); /* token => NULL */ - - The GNU C library contains two more functions for tokenizing a string -which overcome the limitation of non-reentrancy. They are only -available for multibyte character strings. - - - Function: char * strtok_r (char *NEWSTRING, const char *DELIMITERS, - char **SAVE_PTR) - Just like `strtok', this function splits the string into several - tokens which can be accessed by successive calls to `strtok_r'. - The difference is that the information about the next token is - stored in the space pointed to by the third argument, SAVE_PTR, - which is a pointer to a string pointer. Calling `strtok_r' with a - null pointer for NEWSTRING and leaving SAVE_PTR between the calls - unchanged does the job without hindering reentrancy. - - This function is defined in POSIX.1 and can be found on many - systems which support multi-threading. - - - Function: char * strsep (char **STRING_PTR, const char *DELIMITER) - This function has a similar functionality as `strtok_r' with the - NEWSTRING argument replaced by the SAVE_PTR argument. The - initialization of the moving pointer has to be done by the user. - Successive calls to `strsep' move the pointer along the tokens - separated by DELIMITER, returning the address of the next token - and updating STRING_PTR to point to the beginning of the next - token. - - One difference between `strsep' and `strtok_r' is that if the - input string contains more than one character from DELIMITER in a - row `strsep' returns an empty string for each pair of characters - from DELIMITER. This means that a program normally should test - for `strsep' returning an empty string before processing it. - - This function was introduced in 4.3BSD and therefore is widely - available. - - Here is how the above example looks like when `strsep' is used. - - #include - #include - - ... - - const char string[] = "words separated by spaces -- and, punctuation!"; - const char delimiters[] = " .,;:!-"; - char *running; - char *token; - - ... - - running = strdupa (string); - token = strsep (&running, delimiters); /* token => "words" */ - token = strsep (&running, delimiters); /* token => "separated" */ - token = strsep (&running, delimiters); /* token => "by" */ - token = strsep (&running, delimiters); /* token => "spaces" */ - token = strsep (&running, delimiters); /* token => "" */ - token = strsep (&running, delimiters); /* token => "" */ - token = strsep (&running, delimiters); /* token => "" */ - token = strsep (&running, delimiters); /* token => "and" */ - token = strsep (&running, delimiters); /* token => "" */ - token = strsep (&running, delimiters); /* token => "punctuation" */ - token = strsep (&running, delimiters); /* token => "" */ - token = strsep (&running, delimiters); /* token => NULL */ - - - Function: char * basename (const char *FILENAME) - The GNU version of the `basename' function returns the last - component of the path in FILENAME. This function is the prefered - usage, since it does not modify the argument, FILENAME, and - respects trailing slashes. The prototype for `basename' can be - found in `string.h'. Note, this function is overriden by the XPG - version, if `libgen.h' is included. - - Example of using GNU `basename': - - #include - - int - main (int argc, char *argv[]) - { - char *prog = basename (argv[0]); - - if (argc < 2) - { - fprintf (stderr, "Usage %s \n", prog); - exit (1); - } - - ... - } - - *Portability Note:* This function may produce different results on - different systems. - - - - Function: char * basename (char *PATH) - This is the standard XPG defined `basename'. It is similar in - spirit to the GNU version, but may modify the PATH by removing - trailing '/' characters. If the PATH is made up entirely of '/' - characters, then "/" will be returned. Also, if PATH is `NULL' or - an empty string, then "." is returned. The prototype for the XPG - version can be found in `libgen.h'. - - Example of using XPG `basename': - - #include - - int - main (int argc, char *argv[]) - { - char *prog; - char *path = strdupa (argv[0]); - - prog = basename (path); - - if (argc < 2) - { - fprintf (stderr, "Usage %s \n", prog); - exit (1); - } - - ... - - } - - - Function: char * dirname (char *PATH) - The `dirname' function is the compliment to the XPG version of - `basename'. It returns the parent directory of the file specified - by PATH. If PATH is `NULL', an empty string, or contains no '/' - characters, then "." is returned.

This is actually a fairly simple task for C programmers who -do not use the GNU C library string functions, but for programs based -on the GNU C library, the `strfry' function is the preferred method for -destroying string data. - - The prototype for this function is in `string.h'. - - - Function: char * strfry (char *STRING) - `strfry' creates a pseudorandom anagram of a string, replacing the - input with the anagram in place.

It returns a pointer to a 6 character - buffer which contains an encoded version of N. To encode a series - of bytes the user must copy the returned string to a destination - buffer. It returns the empty string if N is zero, which is - somewhat bizarre but mandated by the standard. - *Warning:* Since a static buffer is used this function should not - be used in multi-threaded programs. There is no thread-safe - alternative to this function in the C library. - *Compatibility Note:* The XPG standard states that the return - value of `l64a' is undefined if N is negative. In the GNU - implementation, `l64a' treats its argument as unsigned, so it will - return a sensible encoding for any nonzero N; however, portable - programs should not rely on this. - - To encode a large buffer `l64a' must be called in a loop, once for - each 32-bit word of the buffer.

ARGV must be - pre-allocated with enough space to hold all the elements in ARGZ - plus the terminating `(char *)0' (`(argz_count (ARGZ, ARGZ_LEN) + - 1) * sizeof (char *)' bytes should be enough). Note that the - string pointers stored into ARGV point into ARGZ--they are not - copies--and so ARGZ must be copied if it will be changed while - ARGV is still active. This function is useful for passing the - elements in ARGZ to an exec function (*note Executing a File::). - - - Function: void argz_stringify (char *ARGZ, size_t LEN, int SEP) - The `argz_stringify' converts ARGZ into a normal string with the - elements separated by the character SEP, by replacing each `'\0'' - inside ARGZ (except the last one, which terminates the string) - with SEP. This is handy for printing ARGZ in a readable manner. - - - Function: error_t argz_add (char **ARGZ, size_t *ARGZ_LEN, const - char *STR) - The `argz_add' function adds the string STR to the end of the argz - vector `*ARGZ', and updates `*ARGZ' and `*ARGZ_LEN' accordingly. - - - Function: error_t argz_add_sep (char **ARGZ, size_t *ARGZ_LEN, const - char *STR, int DELIM) - The `argz_add_sep' function is similar to `argz_add', but STR is - split into separate elements in the result at occurrences of the - character DELIM.

If BEFORE is `0', ENTRY is added to the end instead - (as if by `argz_add').

If ENTRY is `0', the first - element of ARGZ is returned. - - This behavior suggests two styles of iteration: - - char *entry = 0; - while ((entry = argz_next (ARGZ, ARGZ_LEN, entry))) - ACTION; - - (the double parentheses are necessary to make some C compilers - shut up about what they consider a questionable `while'-test) and: - - char *entry; - for (entry = ARGZ; - entry; - entry = argz_next (ARGZ, ARGZ_LEN, entry)) - ACTION; - - Note that the latter depends on ARGZ having a value of `0' if it - is empty (rather than a pointer to an empty block of memory); this - invariant is maintained for argz vectors created by the functions - here. - - - Function: error_t argz_replace (char **ARGZ, size_t *ARGZ_LEN, - const char *STR, const char *WITH, unsigned *REPLACE_COUNT) - Replace any occurrences of the string STR in ARGZ with WITH, - reallocating ARGZ as necessary.

The remainder of this section -gives a few examples to help understand the design decisions made while -developing the functionality of the C library. + This function is a GNU extension. - A distinction we have to make right away is between internal and -external representation. "Internal representation" means the -representation used by a program while keeping the text in memory. -External representations are used when text is stored or transmitted -through whatever communication channel. Examples of external -representations include files lying in a directory that are going to be -read and parsed. + One useful, but unusual, use of the `strchr' function is when one +wants to have a pointer pointing to the NUL byte terminating a string. +This is often written in this way: - Traditionally there has been no difference between the two -representations. It was equally comfortable and useful to use the same -single-byte representation internally and externally. This changes -with more and larger character sets. + s += strlen (s); - One of the problems to overcome with the internal representation is -handling text that is externally encoded using different character -sets. Assume a program which reads two texts and compares them using -some metric. The comparison can be usefully done only if the texts are -internally kept in a common format. +This is almost optimal but the addition operation duplicated a bit of +the work already done in the `strlen' function. A better solution is +this: - For such a common format (= character set) eight bits are certainly -no longer enough. So the smallest entity will have to grow: "wide -characters" will now be used. Instead of one byte, two or four will be -used instead. (Three are not good to address in memory and more than -four bytes seem not to be necessary). + s = strchr (s, '\0'); - As shown in some other part of this manual, there exists a -completely new family of functions which can handle texts of this kind -in memory. The most commonly used character sets for such internal -wide character representations are Unicode and ISO 10646 (also known as -UCS for Universal Character Set). Unicode was originally planned as a -16-bit character set, whereas ISO 10646 was designed to be a 31-bit -large code space. The two standards are practically identical. They -have the same character repertoire and code table, but Unicode specifies -added semantics. At the moment, only characters in the first `0x10000' -code positions (the so-called Basic Multilingual Plane, BMP) have been -assigned, but the assignment of more specialized characters outside this -16-bit space is already in progress. A number of encodings have been -defined for Unicode and ISO 10646 characters: UCS-2 is a 16-bit word -that can only represent characters from the BMP, UCS-4 is a 32-bit word -than can represent any Unicode and ISO 10646 character, UTF-8 is an -ASCII compatible encoding where ASCII characters are represented by -ASCII bytes and non-ASCII characters by sequences of 2-6 non-ASCII -bytes, and finally UTF-16 is an extension of UCS-2 in which pairs of -certain UCS-2 words can be used to encode non-BMP characters up to -`0x10ffff'. + There is no restriction on the second parameter of `strchr' so it +could very well also be the NUL character. Those readers thinking very +hard about this might now point out that the `strchr' function is more +expensive than the `strlen' function since we have two abort criteria. +This is right. But in the GNU C library the implementation of `strchr' +is optimized in a special way so that `strchr' actually is faster. - To represent wide characters the `char' type is not suitable. For -this reason the ISO C standard introduces a new type which is designed -to keep one character of a wide character string. To maintain the -similarity there is also a type corresponding to `int' for those -functions which take a single wide character. + - Function: char * strrchr (const char *STRING, int C) + The function `strrchr' is like `strchr', except that it searches + backwards from the end of the string STRING (instead of forwards + from the front). - - Data type: wchar_t - This data type is used as the base type for wide character strings. - I.e., arrays of objects of this type are the equivalent of `char[]' - for multibyte character strings. The type is defined in - `stddef.h'. + For example, + strrchr ("hello, world", 'l') + => "ld" - The ISO C90 standard, where this type was introduced, does not say - anything specific about the representation. It only requires that - this type is capable of storing all elements of the basic - character set. Therefore it would be legitimate to define - `wchar_t' as `char'. This might make sense for embedded systems. + - Function: wchar_t * wcsrchr (const wchar_t *WSTRING, wchar_t C) + The function `wcsrchr' is like `wcschr', except that it searches + backwards from the end of the string WSTRING (instead of forwards + from the front). - But for GNU systems this type is always 32 bits wide. It is - therefore capable of representing all UCS-4 values and therefore - covering all of ISO 10646. Some Unix systems define `wchar_t' as - a 16-bit type and thereby follow Unicode very strictly. This is - perfectly fine with the standard but it also means that to - represent all characters from Unicode and ISO 10646 one has to use - UTF-16 surrogate characters which is in fact a - multi-wide-character encoding. But this contradicts the purpose - of the `wchar_t' type. + - Function: char * strstr (const char *HAYSTACK, const char *NEEDLE) + This is like `strchr', except that it searches HAYSTACK for a + substring NEEDLE rather than just a single character. It returns + a pointer into the string HAYSTACK that is the first character of + the substring, or a null pointer if no match was found.

As the name already suggests it - is the equivalent to `int' when using the normal `char' strings. - The types `wchar_t' and `wint_t' have often the same - representation if their size if 32 bits wide but if `wchar_t' is - defined as `char' the type `wint_t' must be defined as `int' due - to the parameter promotion. + For example, + strstr ("hello, world", "l") + => "llo, world" + strstr ("hello, world", "wo") + => "world" - This type is defined in `wchar.h' and got introduced in - Amendment 1 to ISO C90. + - Function: wchar_t * wcsstr (const wchar_t *HAYSTACK, const wchar_t + *NEEDLE) + This is like `wcschr', except that it searches HAYSTACK for a + substring NEEDLE rather than just a single wide character.

NEEDLE-LEN is the length of + NEEDLE and HAYSTACK-LEN is the length of HAYSTACK. - This macro got introduced in Amendment 1 to ISO C90. + This function is a GNU extension. - Another special wide character value is the equivalent to `EOF'. + - Function: size_t strspn (const char *STRING, const char *SKIPSET) + The `strspn' ("string span") function returns the length of the + initial substring of STRING that consists entirely of characters + that are members of the set specified by the string SKIPSET.

I.e., machines with -different endianesses would see different value accessing the same data. -This also applies for communication protocols which are all byte-based -and therefore the sender has to decide about splitting the wide -character in bytes. A last (but not least important) point is that wide -characters often require more storage space than an customized byte -oriented character set. + - Function: size_t wcscspn (const wchar_t *WSTRING, const wchar_t + *STOPSET) + The `wcscspn' ("wide character string complement span") function + returns the length of the initial substring of WSTRING that + consists entirely of wide characters that are _not_ members of the + set specified by the string STOPSET.

Things are a -bit different for character sets like EBCDIC (Extended Binary Coded -Decimal Interchange Code, a character set family used by IBM) but if the -operation system does not understand EBCDIC directly the parameters to -system calls have to be converted first anyhow. + - Function: char * strpbrk (const char *STRING, const char *STOPSET) + The `strpbrk' ("string pointer break") function is related to + `strcspn', except that it returns a pointer to the first character + in STRING that is a member of the set STOPSET instead of the + length of the initial substring. It returns a null pointer if no + such character from STOPSET is found. - * The simplest character sets are single-byte character sets. There - can be only up to 256 characters (for 8 bit character sets) which - is not sufficient to cover all languages but might be sufficient - to handle a specific text. Another reason to choose this is - because of constraints from interaction with other programs (which - might not be 8-bit clean). + For example, - * The ISO 2022 standard defines a mechanism for extended character - sets where one character _can_ be represented by more than one - byte. This is achieved by associating a state with the text. - Embedded in the text can be characters which can be used to change - the state. Each byte in the text might have a different - interpretation in each state. The state might even influence - whether a given byte stands for a character on its own or whether - it has to be combined with some more bytes. + strpbrk ("hello, world", " \t\n,.;!?") + => ", world" - In most uses of ISO 2022 the defined character sets do not allow - state changes which cover more than the next character. This has - the big advantage that whenever one can identify the beginning of - the byte sequence of a character one can interpret a text - correctly. Examples of character sets using this policy are the - various EUC character sets (used by Sun's operations systems, - EUC-JP, EUC-KR, EUC-TW, and EUC-CN) or Shift_JIS (SJIS, a Japanese - encoding). + Note that "character" is here used in the sense of byte. In a + string using a multibyte character encoding (abstract) character + consisting of more than one byte are not treated as an entity. + Each byte is treated separately. The function is not + locale-dependent. - But there are also character sets using a state which is valid for - more than one character and has to be changed by another byte - sequence. Examples for this are ISO-2022-JP, ISO-2022-KR, and - ISO-2022-CN. + - Function: wchar_t * wcspbrk (const wchar_t *WSTRING, const wchar_t + *STOPSET) + The `wcspbrk' ("wide character string pointer break") function is + related to `wcscspn', except that it returns a pointer to the first + wide character in WSTRING that is a member of the set STOPSET + instead of the length of the initial substring. It returns a null + pointer if no such character from STOPSET is found. - * Early attempts to fix 8 bit character sets for other languages - using the Roman alphabet lead to character sets like ISO 6937. - Here bytes representing characters like the acute accent do not - produce output themselves: one has to combine them with other - characters to get the desired result. E.g., the byte sequence - `0xc2 0x61' (non-spacing acute accent, following by lower-case - `a') to get the "small a with acute" character. To get the acute - accent character on its own, one has to write `0xc2 0x20' (the - non-spacing acute followed by a space). +Compatibility String Search Functions +------------------------------------- - This type of character set is used in some embedded systems such as - teletex. + - Function: char * index (const char *STRING, int C) + `index' is another name for `strchr'; they are exactly the same. + New code should always use `strchr' since this name is defined in + ISO C while `index' is a BSD invention which never was available + on System V derived systems. - * Instead of converting the Unicode or ISO 10646 text used - internally, it is often also sufficient to simply use an encoding - different than UCS-2/UCS-4. The Unicode and ISO 10646 standards - even specify such an encoding: UTF-8. This encoding is able to - represent all of ISO 10464 31 bits in a byte string of length one - to six. + - Function: char * rindex (const char *STRING, int C) + `rindex' is another name for `strrchr'; they are exactly the same. + New code should always use `strrchr' since this name is defined in + ISO C while `rindex' is a BSD invention which never was available + on System V derived systems. - There were a few other attempts to encode ISO 10646 such as UTF-7 - but UTF-8 is today the only encoding which should be used. In - fact, UTF-8 will hopefully soon be the only external encoding that - has to be supported. It proves to be universally usable and the - only disadvantage is that it favors Roman languages by making the - byte string representation of other scripts (Cyrillic, Greek, - Asian scripts) longer than necessary if using a specific character - set for these scripts. Methods like the Unicode compression - scheme can alleviate these problems. + +File: libc.info, Node: Finding Tokens in a String, Next: strfry, Prev: Search Functions, Up: String and Array Utilities - The question remaining is: how to select the character set or -encoding to use. The answer: you cannot decide about it yourself, it -is decided by the developers of the system or the majority of the -users. Since the goal is interoperability one has to use whatever the -other people one works with use. If there are no constraints the -selection is based on the requirements the expected circle of users -will have. I.e., if a project is expected to only be used in, say, -Russia it is fine to use KOI8-R or a similar character set. But if at -the same time people from, say, Greece are participating one should use -a character set which allows all people to collaborate. +Finding Tokens in a String +========================== - The most widely useful solution seems to be: go with the most general -character set, namely ISO 10646. Use UTF-8 as the external encoding -and problems about users not being able to use their own language -adequately are a thing of the past. + It's fairly common for programs to have a need to do some simple +kinds of lexical analysis and parsing, such as splitting a command +string up into tokens. You can do this with the `strtok' function, +declared in the header file `string.h'. - One final comment about the choice of the wide character -representation is necessary at this point. We have said above that the -natural choice is using Unicode or ISO 10646. This is not required, -but at least encouraged, by the ISO C standard. The standard defines -at least a macro `__STDC_ISO_10646__' that is only defined on systems -where the `wchar_t' type encodes ISO 10646 characters. If this symbol -is not defined one should as much as possible avoid making assumption -about the wide character representation. If the programmer uses only -the functions provided by the C library to handle wide character -strings there should not be any compatibility problems with other -systems. + - Function: char * strtok (char *restrict NEWSTRING, const char + *restrict DELIMITERS) + A string can be split into tokens by making a series of calls to + the function `strtok'. - -File: libc.info, Node: Charset Function Overview, Next: Restartable multibyte conversion, Prev: Extended Char Intro, Up: Character Set Handling + The string to be split up is passed as the NEWSTRING argument on + the first call only. The `strtok' function uses this to set up + some internal state information. Subsequent calls to get + additional tokens from the same string are indicated by passing a + null pointer as the NEWSTRING argument. Calling `strtok' with + another non-null NEWSTRING argument reinitializes the state + information. It is guaranteed that no other library function ever + calls `strtok' behind your back (which would mess up this internal + state information). -Overview about Character Handling Functions -=========================================== + The DELIMITERS argument is a string that specifies a set of + delimiters that may surround the token being extracted. All the + initial characters that are members of this set are discarded. + The first character that is _not_ a member of this set of + delimiters marks the beginning of the next token. The end of the + token is found by looking for the next character that is a member + of the delimiter set. This character in the original string + NEWSTRING is overwritten by a null character, and the pointer to + the beginning of the token in NEWSTRING is returned. - A Unix C library contains three different sets of functions in two -families to handle character set conversion. The one function family -is specified in the ISO C standard and therefore is portable even -beyond the Unix world. + On the next call to `strtok', the searching begins at the next + character beyond the one that marked the end of the previous token. + Note that the set of delimiters DELIMITERS do not have to be the + same on every call in a series of calls to `strtok'. - The most commonly known set of functions, coming from the ISO C90 -standard, is unfortunately the least useful one. In fact, these -functions should be avoided whenever possible, especially when -developing libraries (as opposed to applications). + If the end of the string NEWSTRING is reached, or if the remainder + of string consists only of delimiter characters, `strtok' returns + a null pointer. - The second family of functions got introduced in the early Unix -standards (XPG2) and is still part of the latest and greatest Unix -standard: Unix 98. It is also the most powerful and useful set of -functions. But we will start with the functions defined in Amendment 1 -to ISO C90. + Note that "character" is here used in the sense of byte. In a + string using a multibyte character encoding (abstract) character + consisting of more than one byte are not treated as an entity. + Each byte is treated separately.

The function is not + locale-dependent. -Restartable Multibyte Conversion Functions -========================================== + - Function: wchar_t * wcstok (wchar_t *NEWSTRING, const char + *DELIMITERS) + A string can be split into tokens by making a series of calls to + the function `wcstok'. - The ISO C standard defines functions to convert strings from a -multibyte representation to wide character strings. There are a number -of peculiarities: + The string to be split up is passed as the NEWSTRING argument on + the first call only. The `wcstok' function uses this to set up + some internal state information. Subsequent calls to get + additional tokens from the same wide character string are + indicated by passing a null pointer as the NEWSTRING argument. + Calling `wcstok' with another non-null NEWSTRING argument + reinitializes the state information. It is guaranteed that no + other library function ever calls `wcstok' behind your back (which + would mess up this internal state information). - * The character set assumed for the multibyte encoding is not - specified as an argument to the functions. Instead the character - set specified by the `LC_CTYPE' category of the current locale is - used; see *Note Locale Categories::. + The DELIMITERS argument is a wide character string that specifies + a set of delimiters that may surround the token being extracted. + All the initial wide characters that are members of this set are + discarded. The first wide character that is _not_ a member of + this set of delimiters marks the beginning of the next token. The + end of the token is found by looking for the next wide character + that is a member of the delimiter set. This wide character in the + original wide character string NEWSTRING is overwritten by a null + wide character, and the pointer to the beginning of the token in + NEWSTRING is returned. - * The functions handling more than one character at a time require - NUL terminated strings as the argument. I.e., converting blocks - of text does not work unless one can add a NUL byte at an - appropriate place. The GNU C library contains some extensions the - standard which allow specifying a size but basically they also - expect terminated strings. + On the next call to `wcstok', the searching begins at the next + wide character beyond the one that marked the end of the previous + token. Note that the set of delimiters DELIMITERS do not have to + be the same on every call in a series of calls to `wcstok'. - Despite these limitations the ISO C functions can very well be used -in many contexts. In graphical user interfaces, for instance, it is not -uncommon to have functions which require text to be displayed in a wide -character string if it is not simple ASCII. The text itself might come -from a file with translations and the user should decide about the -current locale which determines the translation and therefore also the -external encoding used. In such a situation (and many others) the -functions described here are perfect. If more freedom while performing -the conversion is necessary take a look at the `iconv' functions (*note -Generic Charset Conversion::). + If the end of the wide character string NEWSTRING is reached, or + if the remainder of string consists only of delimiter wide + characters, `wcstok' returns a null pointer. -* Menu: + Note that "character" is here used in the sense of byte. In a + string using a multibyte character encoding (abstract) character + consisting of more than one byte are not treated as an entity. + Each byte is treated separately. The function is not + locale-dependent. -* Selecting the Conversion:: Selecting the conversion and its properties. -* Keeping the state:: Representing the state of the conversion. -* Converting a Character:: Converting Single Characters. -* Converting Strings:: Converting Multibyte and Wide Character - Strings. -* Multibyte Conversion Example:: A Complete Multibyte Conversion Example. + *Warning:* Since `strtok' and `wcstok' alter the string they is +parsing, you should always copy the string to a temporary buffer before +parsing it with `strtok'/`wcstok' (*note Copying and Concatenation::). +If you allow `strtok' or `wcstok' to modify a string that came from +another part of your program, you are asking for trouble; that string +might be used for other purposes after `strtok' or `wcstok' has +modified it, and it would not have the expected value. - -File: libc.info, Node: Selecting the Conversion, Next: Keeping the state, Up: Restartable multibyte conversion + The string that you are operating on might even be a constant. Then +when `strtok' or `wcstok' tries to modify it, your program will get a +fatal signal for writing in read-only memory. *Note Program Error +Signals::. Even if the operation of `strtok' or `wcstok' would not +require a modification of the string (e.g., if there is exactly one +token) the string can (and in the GNU libc case will) be modified. -Selecting the conversion and its properties -------------------------------------------- + This is a special case of a general principle: if a part of a program +does not have as its purpose the modification of a certain data +structure, then it is error-prone to modify the data structure +temporarily. - We already said above that the currently selected locale for the -`LC_CTYPE' category decides about the conversion which is performed by -the functions we are about to describe. Each locale uses its own -character set (given as an argument to `localedef') and this is the one -assumed as the external multibyte encoding. The wide character -character set always is UCS-4, at least on GNU systems. + The functions `strtok' and `wcstok' are not reentrant. *Note +Nonreentrancy::, for a discussion of where and why reentrancy is +important. - A characteristic of each multibyte character set is the maximum -number of bytes which can be necessary to represent one character. This -information is quite important when writing code which uses the -conversion functions. In the examples below we will see some examples. -The ISO C standard defines two macros which provide this information. + Here is a simple example showing the use of `strtok'. - - Macro: int MB_LEN_MAX - This macro specifies the maximum number of bytes in the multibyte - sequence for a single character in any of the supported locales. - It is a compile-time constant and it is defined in `limits.h'. + #include + #include + + ... + + const char string[] = "words separated by spaces -- and, punctuation!"; + const char delimiters[] = " .,;:!-"; + char *token, *cp; + + ... + + cp = strdupa (string); /* Make writable copy. */ + token = strtok (cp, delimiters); /* token => "words" */ + token = strtok (NULL, delimiters); /* token => "separated" */ + token = strtok (NULL, delimiters); /* token => "by" */ + token = strtok (NULL, delimiters); /* token => "spaces" */ + token = strtok (NULL, delimiters); /* token => "and" */ + token = strtok (NULL, delimiters); /* token => "punctuation" */ + token = strtok (NULL, delimiters); /* token => NULL */ - - Macro: int MB_CUR_MAX - `MB_CUR_MAX' expands into a positive integer expression that is the - maximum number of bytes in a multibyte character in the current - locale. The value is never greater than `MB_LEN_MAX'. Unlike - `MB_LEN_MAX' this macro need not be a compile-time constant and in - fact, in the GNU C library it is not. + The GNU C library contains two more functions for tokenizing a string +which overcome the limitation of non-reentrancy. They are only +available for multibyte character strings. - `MB_CUR_MAX' is defined in `stdlib.h'. + - Function: char * strtok_r (char *NEWSTRING, const char *DELIMITERS, + char **SAVE_PTR) + Just like `strtok', this function splits the string into several + tokens which can be accessed by successive calls to `strtok_r'. + The difference is that the information about the next token is + stored in the space pointed to by the third argument, SAVE_PTR, + which is a pointer to a string pointer. Calling `strtok_r' with a + null pointer for NEWSTRING and leaving SAVE_PTR between the calls + unchanged does the job without hindering reentrancy. - Two different macros are necessary since strictly ISO C90 compilers -do not allow variable length array definitions but still it is desirable -to avoid dynamic allocation. This incomplete piece of code shows the -problem: + This function is defined in POSIX.1 and can be found on many + systems which support multi-threading. - { - char buf[MB_LEN_MAX]; - ssize_t len = 0; + - Function: char * strsep (char **STRING_PTR, const char *DELIMITER) + This function has a similar functionality as `strtok_r' with the + NEWSTRING argument replaced by the SAVE_PTR argument. The + initialization of the moving pointer has to be done by the user. + Successive calls to `strsep' move the pointer along the tokens + separated by DELIMITER, returning the address of the next token + and updating STRING_PTR to point to the beginning of the next + token. + + One difference between `strsep' and `strtok_r' is that if the + input string contains more than one character from DELIMITER in a + row `strsep' returns an empty string for each pair of characters + from DELIMITER. This means that a program normally should test + for `strsep' returning an empty string before processing it. + + This function was introduced in 4.3BSD and therefore is widely + available. + + Here is how the above example looks like when `strsep' is used. + + #include + #include - while (! feof (fp)) - { - fread (&buf[len], 1, MB_CUR_MAX - len, fp); - /* ... process buf */ - len -= used; - } - } + ... + + const char string[] = "words separated by spaces -- and, punctuation!"; + const char delimiters[] = " .,;:!-"; + char *running; + char *token; + + ... + + running = strdupa (string); + token = strsep (&running, delimiters); /* token => "words" */ + token = strsep (&running, delimiters); /* token => "separated" */ + token = strsep (&running, delimiters); /* token => "by" */ + token = strsep (&running, delimiters); /* token => "spaces" */ + token = strsep (&running, delimiters); /* token => "" */ + token = strsep (&running, delimiters); /* token => "" */ + token = strsep (&running, delimiters); /* token => "" */ + token = strsep (&running, delimiters); /* token => "and" */ + token = strsep (&running, delimiters); /* token => "" */ + token = strsep (&running, delimiters); /* token => "punctuation" */ + token = strsep (&running, delimiters); /* token => "" */ + token = strsep (&running, delimiters); /* token => NULL */ - The code in the inner loop is expected to have always enough bytes in -the array BUF to convert one multibyte character. The array BUF has to -be sized statically since many compilers do not allow a variable size. -The `fread' call makes sure that always `MB_CUR_MAX' bytes are -available in BUF. Note that it isn't a problem if `MB_CUR_MAX' is not -a compile-time constant. + - Function: char * basename (const char *FILENAME) + The GNU version of the `basename' function returns the last + component of the path in FILENAME. This function is the preferred + usage, since it does not modify the argument, FILENAME, and + respects trailing slashes. The prototype for `basename' can be + found in `string.h'. Note, this function is overriden by the XPG + version, if `libgen.h' is included. + + Example of using GNU `basename': + + #include + + int + main (int argc, char *argv[]) + { + char *prog = basename (argv[0]); + + if (argc < 2) + { + fprintf (stderr, "Usage %s \n", prog); + exit (1); + } + + ... + } + + *Portability Note:* This function may produce different results on + different systems. + + + - Function: char * basename (char *PATH) + This is the standard XPG defined `basename'. It is similar in + spirit to the GNU version, but may modify the PATH by removing + trailing '/' characters. If the PATH is made up entirely of '/' + characters, then "/" will be returned. Also, if PATH is `NULL' or + an empty string, then "." is returned. The prototype for the XPG + version can be found in `libgen.h'. + + Example of using XPG `basename': + + #include + + int + main (int argc, char *argv[]) + { + char *prog; + char *path = strdupa (argv[0]); + + prog = basename (path); + + if (argc < 2) + { + fprintf (stderr, "Usage %s \n", prog); + exit (1); + } + + ... + + } + + - Function: char * dirname (char *PATH) + The `dirname' function is the compliment to the XPG version of + `basename'. It returns the parent directory of the file specified + by PATH. If PATH is `NULL', an empty string, or contains no '/' + characters, then "." is returned. The prototype for this function + can be found in `libgen.h'.  -File: libc.info, Node: Keeping the state, Next: Converting a Character, Prev: Selecting the Conversion, Up: Restartable multibyte conversion +File: libc.info, Node: strfry, Next: Trivial Encryption, Prev: Finding Tokens in a String, Up: String and Array Utilities -Representing the state of the conversion ----------------------------------------- +strfry +====== - In the introduction of this chapter it was said that certain -character sets use a "stateful" encoding. I.e., the encoded values -depend in some way on the previous bytes in the text. + The function below addresses the perennial programming quandary: +"How do I take good data in string form and painlessly turn it into +garbage?"

The two positions may be the same. - This type is defined in `wchar.h'. It got introduced in - Amendment 1 to ISO C90. + The return value of `strfry' is always STRING. - To use objects of this type the programmer has to define such objects -(normally as local variables on the stack) and pass a pointer to the -object to the conversion functions. This way the conversion function -can update the object if the current multibyte character set is -stateful. + *Portability Note:* This function is unique to the GNU C library. - There is no specific function or initializer to put the state object -in any specific state. The rules are that the object should always -represent the initial state before the first use and this is achieved by -clearing the whole variable with code such as follows: - { - mbstate_t state; - memset (&state, '\0', sizeof (state)); - /* from now on STATE can be used. */ - ... - } + +File: libc.info, Node: Trivial Encryption, Next: Encode Binary Data, Prev: strfry, Up: String and Array Utilities - When using the conversion functions to generate output it is often -necessary to test whether the current state corresponds to the initial -state.

There is no `mbstate_t' object used from - which the state information is taken and the function also does - not use any static state. + char * + encode (const void *buf, size_t len) + { + /* We know in advance how long the buffer has to be. */ + unsigned char *in = (unsigned char *) buf; + char *out = malloc (6 + ((len + 3) / 4) * 6 + 1); + char *cp = out; + + /* Encode the length. */ + /* Using `htonl' is necessary so that the data can be + decoded even on machines with different byte order. */ + + cp = mempcpy (cp, l64a (htonl (len)), 6); + + while (len > 3) + { + unsigned long int n = *in++; + n = (n << 8) | *in++; + n = (n << 8) | *in++; + n = (n << 8) | *in++; + len -= 4; + if (n) + cp = mempcpy (cp, l64a (htonl (n)), 6); + else + /* `l64a' returns the empty string for n==0, so we + must generate its encoding ("......") by hand. */ + cp = stpcpy (cp, "......"); + } + if (len > 0) + { + unsigned long int n = *in++; + if (--len > 0) + { + n = (n << 8) | *in++; + if (--len > 0) + n = (n << 8) | *in; + } + memcpy (cp, l64a (htonl (n)), 6); + cp += 6; + } + *cp = '\0'; + return out; + } - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. + It is strange that the library does not provide the complete + functionality needed but so be it. - Despite the limitation that the single byte value always is -interpreted in the initial state this function is actually useful most -of the time. Most characters are either entirely single-byte character -sets or they are extension to ASCII. But then it is possible to write -code like this (not that this specific example is very useful): - wchar_t * - itow (unsigned long int val) - { - static wchar_t buf[30]; - wchar_t *wcp = &buf[29]; - *wcp = L'\0'; - while (val != 0) - { - *--wcp = btowc ('0' + val % 10); - val /= 10; - } - if (wcp == &buf[29]) - *--wcp = L'0'; - return wcp; - } + To decode data produced with `l64a' the following function should be +used. - Why is it necessary to use such a complicated implementation and not -simply cast `'0' + val % 10' to a wide character? The answer is that -there is no guarantee that one can perform this kind of arithmetic on -the character of the character set used for `wchar_t' representation. -In other situations the bytes are not constant at compile time and so -the compiler cannot do the work. In situations like this it is -necessary `btowc'. + - Function: long int a64l (const char *STRING) + The parameter STRING should contain a string which was produced by + a call to `l64a'. The function processes at least 6 characters of + this string, and decodes the characters it finds according to the + table below. It stops decoding when it finds a character not in + the table, rather like `atoi'; if you have a buffer which has been + broken into lines, you must be careful to skip over the + end-of-line characters. -There also is a function for the conversion in the other direction. + The decoded number is returned as a `long int' value. - - Function: int wctob (wint_t C) - The `wctob' function ("wide character to byte") takes as the - parameter a valid wide character. If the multibyte representation - for this character in the initial state is exactly one byte long - the return value of this function is this character. Otherwise - the return value is `EOF'. + The `l64a' and `a64l' functions use a base 64 encoding, in which +each character of an encoded string represents six bits of an input +word.

There are some other encoding +methods which are much more widely used (UU encoding, MIME encoding). +Generally, it is better to use one of these encodings. - - Function: size_t mbrtowc (wchar_t *restrict PWC, const char - *restrict S, size_t N, mbstate_t *restrict PS) - The `mbrtowc' function ("multibyte restartable to wide character") - converts the next multibyte character in the string pointed to by - S into a wide character and stores it in the wide character string - pointed to by PWC. The conversion is performed according to the - locale currently selected for the `LC_CTYPE' category.

If the next N or fewer - bytes form a correct multibyte character the return value is the - number of bytes starting from S which form the multibyte - character. The conversion state is updated according to the bytes - consumed in the conversion. In both cases the wide character - (either the `L'\0'' or the one found in the conversion) is stored - in the string pointer to by PWC iff PWC is not null. +Argz and Envz Vectors +===================== - If the first N bytes of the multibyte string possibly form a valid - multibyte character but there are more than N bytes needed to - complete it the return value of the function is `(size_t) -2' and - no value is stored. Please note that this can happen even if N - has a value greater or equal to `MB_CUR_MAX' since the input might - contain redundant shift sequences. + "argz vectors" are vectors of strings in a contiguous block of +memory, each element separated from its neighbors by null-characters +(`'\0''). - If the first `n' bytes of the multibyte string cannot possibly form - a valid multibyte character also no value is stored, the global - variable `errno' is set to the value `EILSEQ' and the function - returns `(size_t) -1'. The conversion state is afterwards - undefined. + "Envz vectors" are an extension of argz vectors where each element +is a name-value pair, separated by a `'='' character (as in a Unix +environment). - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. +* Menu: - Using this function is straight forward. A function which copies a -multibyte string into a wide character string while at the same time -converting all lowercase character into uppercase could look like this -(this is not the final version, just an example; it has no error -checking, and leaks sometimes memory): +* Argz Functions:: Operations on argz vectors. +* Envz Functions:: Additional operations on environment vectors. - wchar_t * - mbstouwcs (const char *s) - { - size_t len = strlen (s); - wchar_t *result = malloc ((len + 1) * sizeof (wchar_t)); - wchar_t *wcp = result; - wchar_t tmp[1]; - mbstate_t state; - size_t nbytes; - - memset (&state, '\0', sizeof (state)); - while ((nbytes = mbrtowc (tmp, s, len, &state)) > 0) - { - if (nbytes >= (size_t) -2) - /* Invalid input string. */ - return NULL; - *result++ = towupper (tmp[0]); - len -= nbytes; - s += nbytes; - } - return result; - } + +File: libc.info, Node: Argz Functions, Next: Envz Functions, Up: Argz and Envz Vectors - The use of `mbrtowc' should be clear. A single wide character is -stored in `TMP[0]' and the number of consumed bytes is stored in the -variable NBYTES. In case the the conversion was successful the -uppercase variant of the wide character is stored in the RESULT array -and the pointer to the input string and the number of available bytes -is adjusted. +Argz Functions +-------------- - The only non-obvious thing about the function might be the way -memory is allocated for the result. The above code uses the fact that -there can never be more wide characters in the converted results than -there are bytes in the multibyte input string. This method yields to a -pessimistic guess about the size of the result and if many wide -character strings have to be constructed this way or the strings are -long, the extra memory required allocated because the input string -contains multibyte characters might be significant. It would be -possible to resize the allocated memory block to the correct size before -returning it. A better solution might be to allocate just the right -amount of space for the result right away. Unfortunately there is no -function to compute the length of the wide character string directly -from the multibyte string. But there is a function which does part of -the work. + Each argz vector is represented by a pointer to the first element, of +type `char *', and a size, of type `size_t', both of which can be +initialized to `0' to represent an empty argz vector. All argz +functions accept either a pointer and a size argument, or pointers to +them, if they will be modified. - - Function: size_t mbrlen (const char *restrict S, size_t N, mbstate_t - *PS) - The `mbrlen' function ("multibyte restartable length") computes - the number of at most N bytes starting at S which form the next - valid and complete multibyte character. + The argz functions use `malloc'/`realloc' to allocate/grow argz +vectors, and so any argz vector creating using these functions may be +freed by using `free'; conversely, any argz function that may grow a +string expects that string to have been allocated using `malloc' (those +argz functions that only examine their arguments or modify them in +place will work on any sort of memory). *Note Unconstrained +Allocation::. - If the next multibyte character corresponds to the NUL wide - character the return value is 0. If the next N bytes form a valid - multibyte character the number of bytes belonging to this multibyte - character byte sequence is returned. + All argz functions that do memory allocation have a return type of +`error_t', and return `0' for success, and `ENOMEM' if an allocation +error occurs. - If the the first N bytes possibly form a valid multibyte character - but it is incomplete the return value is `(size_t) -2'. Otherwise - the multibyte character sequence is invalid and the return value - is `(size_t) -1'. + These functions are declared in the standard include file `argz.h'. - The multibyte sequence is interpreted in the state represented by - the object pointed to by PS. If PS is a null pointer, a state - object local to `mbrlen' is used. + - Function: error_t argz_create (char *const ARGV[], char **ARGZ, + size_t *ARGZ_LEN) + The `argz_create' function converts the Unix-style argument vector + ARGV (a vector of pointers to normal C strings, terminated by + `(char *)0'; *note Program Arguments::) into an argz vector with + the same elements, which is returned in ARGZ and ARGZ_LEN. - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. + - Function: error_t argz_create_sep (const char *STRING, int SEP, char + **ARGZ, size_t *ARGZ_LEN) + The `argz_create_sep' function converts the null-terminated string + STRING into an argz vector (returned in ARGZ and ARGZ_LEN) by + splitting it into elements at every occurrence of the character + SEP. - The tentative reader now will of course note that `mbrlen' can be -implemented as + - Function: size_t argz_count (const char *ARGZ, size_t ARG_LEN) + Returns the number of elements in the argz vector ARGZ and + ARGZ_LEN. - mbrtowc (NULL, s, n, ps != NULL ? ps : &internal) + - Function: void argz_extract (char *ARGZ, size_t ARGZ_LEN, char + **ARGV) + The `argz_extract' function converts the argz vector ARGZ and + ARGZ_LEN into a Unix-style argument vector stored in ARGV, by + putting pointers to every element in ARGZ into successive + positions in ARGV, followed by a terminator of `0'. ARGV must be + pre-allocated with enough space to hold all the elements in ARGZ + plus the terminating `(char *)0' (`(argz_count (ARGZ, ARGZ_LEN) + + 1) * sizeof (char *)' bytes should be enough). Note that the + string pointers stored into ARGV point into ARGZ--they are not + copies--and so ARGZ must be copied if it will be changed while + ARGV is still active. This function is useful for passing the + elements in ARGZ to an exec function (*note Executing a File::). - This is true and in fact is mentioned in the official specification. -Now, how can this function be used to determine the length of the wide -character string created from a multibyte character string? It is not -directly usable but we can define a function `mbslen' using it: + - Function: void argz_stringify (char *ARGZ, size_t LEN, int SEP) + The `argz_stringify' converts ARGZ into a normal string with the + elements separated by the character SEP, by replacing each `'\0'' + inside ARGZ (except the last one, which terminates the string) + with SEP. This is handy for printing ARGZ in a readable manner. - size_t - mbslen (const char *s) - { - mbstate_t state; - size_t result = 0; - size_t nbytes; - memset (&state, '\0', sizeof (state)); - while ((nbytes = mbrlen (s, MB_LEN_MAX, &state)) > 0) - { - if (nbytes >= (size_t) -2) - /* Something is wrong. */ - return (size_t) -1; - s += nbytes; - ++result; - } - return result; - } + - Function: error_t argz_add (char **ARGZ, size_t *ARGZ_LEN, const + char *STR) + The `argz_add' function adds the string STR to the end of the argz + vector `*ARGZ', and updates `*ARGZ' and `*ARGZ_LEN' accordingly. - This function simply calls `mbrlen' for each multibyte character in -the string and counts the number of function calls. Please note that -we here use `MB_LEN_MAX' as the size argument in the `mbrlen' call. -This is OK since a) this value is larger then the length of the longest -multibyte character sequence and b) because we know that the string S -ends with a NUL byte which cannot be part of any other multibyte -character sequence but the one representing the NUL wide character. -Therefore the `mbrlen' function will never read invalid memory. + - Function: error_t argz_add_sep (char **ARGZ, size_t *ARGZ_LEN, const + char *STR, int DELIM) + The `argz_add_sep' function is similar to `argz_add', but STR is + split into separate elements in the result at occurrences of the + character DELIM. This is useful, for instance, for adding the + components of a Unix search path to an argz vector, by using a + value of `':'' for DELIM. - Now that this function is available (just to make this clear, this -function is _not_ part of the GNU C library) we can compute the number -of wide character required to store the converted multibyte character -string S using + - Function: error_t argz_append (char **ARGZ, size_t *ARGZ_LEN, const + char *BUF, size_t BUF_LEN) + The `argz_append' function appends BUF_LEN bytes starting at BUF + to the argz vector `*ARGZ', reallocating `*ARGZ' to accommodate + it, and adding BUF_LEN to `*ARGZ_LEN'. - wcs_bytes = (mbslen (s) + 1) * sizeof (wchar_t); + - Function: error_t argz_delete (char **ARGZ, size_t *ARGZ_LEN, char + *ENTRY) + If ENTRY points to the beginning of one of the elements in the + argz vector `*ARGZ', the `argz_delete' function will remove this + entry and reallocate `*ARGZ', modifying `*ARGZ' and `*ARGZ_LEN' + accordingly. Note that as destructive argz functions usually + reallocate their argz argument, pointers into argz vectors such as + ENTRY will then become invalid. - Please note that the `mbslen' function is quite inefficient. The -implementation of `mbstouwcs' implemented using `mbslen' would have to -perform the conversion of the multibyte character input string twice -and this conversion might be quite expensive. So it is necessary to -think about the consequences of using the easier but imprecise method -before doing the work twice. + - Function: error_t argz_insert (char **ARGZ, size_t *ARGZ_LEN, char + *BEFORE, const char *ENTRY) + The `argz_insert' function inserts the string ENTRY into the argz + vector `*ARGZ' at a point just before the existing element pointed + to by BEFORE, reallocating `*ARGZ' and updating `*ARGZ' and + `*ARGZ_LEN'. If BEFORE is `0', ENTRY is added to the end instead + (as if by `argz_add'). Since the first element is in fact the + same as `*ARGZ', passing in `*ARGZ' as the value of BEFORE will + result in ENTRY being inserted at the beginning. - - Function: size_t wcrtomb (char *restrict S, wchar_t WC, mbstate_t - *restrict PS) - The `wcrtomb' function ("wide character restartable to multibyte") - converts a single wide character into a multibyte string - corresponding to that wide character. + - Function: char * argz_next (char *ARGZ, size_t ARGZ_LEN, const char + *ENTRY) + The `argz_next' function provides a convenient way of iterating + over the elements in the argz vector ARGZ. It returns a pointer + to the next element in ARGZ after the element ENTRY, or `0' if + there are no elements following ENTRY. If ENTRY is `0', the first + element of ARGZ is returned. - If S is a null pointer the function resets the the state stored in - the objects pointer to by PS (or the internal `mbstate_t' object) - to the initial state. This can also be achieved by a call like - this: + This behavior suggests two styles of iteration: - wcrtombs (temp_buf, L'\0', ps) + char *entry = 0; + while ((entry = argz_next (ARGZ, ARGZ_LEN, entry))) + ACTION; - since if S is a null pointer `wcrtomb' performs as if it writes - into an internal buffer which is guaranteed to be large enough. + (the double parentheses are necessary to make some C compilers + shut up about what they consider a questionable `while'-test) and: - If WC is the NUL wide character `wcrtomb' emits, if necessary, a - shift sequence to get the state PS into the initial state followed - by a single NUL byte is stored in the string S. + char *entry; + for (entry = ARGZ; + entry; + entry = argz_next (ARGZ, ARGZ_LEN, entry)) + ACTION; - Otherwise a byte sequence (possibly including shift sequences) is - written into the string S. This of only happens if WC is a valid - wide character, i.e., it has a multibyte representation in the - character set selected by locale of the `LC_CTYPE' category. If - WC is no valid wide character nothing is stored in the strings S, - `errno' is set to `EILSEQ', the conversion state in PS is - undefined and the return value is `(size_t) -1'. + Note that the latter depends on ARGZ having a value of `0' if it + is empty (rather than a pointer to an empty block of memory); this + invariant is maintained for argz vectors created by the functions + here. - If no error occurred the function returns the number of bytes - stored in the string S. This includes all byte representing shift - sequences. + - Function: error_t argz_replace (char **ARGZ, size_t *ARGZ_LEN, + const char *STR, const char *WITH, unsigned *REPLACE_COUNT) + Replace any occurrences of the string STR in ARGZ with WITH, + reallocating ARGZ as necessary. If REPLACE_COUNT is non-zero, + `*REPLACE_COUNT' will be incremented by number of replacements + performed. - One word about the interface of the function: there is no parameter - specifying the length of the array S. Instead the function - assumes that there are at least `MB_CUR_MAX' bytes available since - this is the maximum length of any byte sequence representing a - single character. So the caller has to make sure that there is - enough space available, otherwise buffer overruns can occur. + +File: libc.info, Node: Envz Functions, Prev: Argz Functions, Up: Argz and Envz Vectors - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. +Envz Functions +-------------- - Using this function is as easy as using `mbrtowc'. The following -example appends a wide character string to a multibyte character string. -Again, the code is not really useful (and correct), it is simply here to -demonstrate the use and some problems. + Envz vectors are just argz vectors with additional constraints on +the form of each element; as such, argz functions can also be used on +them, where it makes sense. - char * - mbscatwcs (char *s, size_t len, const wchar_t *ws) - { - mbstate_t state; - /* Find the end of the existing string. */ - char *wp = strchr (s, '\0'); - len -= wp - s; - memset (&state, '\0', sizeof (state)); - do - { - size_t nbytes; - if (len < MB_CUR_LEN) - { - /* We cannot guarantee that the next - character fits into the buffer, so - return an error. */ - errno = E2BIG; - return NULL; - } - nbytes = wcrtomb (wp, *ws, &state); - if (nbytes == (size_t) -1) - /* Error in the conversion. */ - return NULL; - len -= nbytes; - wp += nbytes; - } - while (*ws++ != L'\0'); - return s; - } + Each element in an envz vector is a name-value pair, separated by a +`'='' character; if multiple `'='' characters are present in an +element, those after the first are considered part of the value, and +treated like all other non-`'\0'' characters. - First the function has to find the end of the string currently in the -array S. The `strchr' call does this very efficiently since a -requirement for multibyte character representations is that the NUL byte -never is used except to represent itself (and in this context, the end -of the string). + If _no_ `'='' characters are present in an element, that element is +considered the name of a "null" entry, as distinct from an entry with an +empty value: `envz_get' will return `0' if given the name of null +entry, whereas an entry with an empty value would result in a value of +`""'; `envz_entry' will still find such entries, however. Null entries +can be removed with `envz_strip' function. - After initializing the state object the loop is entered where the -first task is to make sure there is enough room in the array S. We -abort if there are not at least `MB_CUR_LEN' bytes available. This is -not always optimal but we have no other choice. We might have less -than `MB_CUR_LEN' bytes available but the next multibyte character -might also be only one byte long. At the time the `wcrtomb' call -returns it is too late to decide whether the buffer was large enough or -not.

The -most unusual thing about this piece of code certainly is the -duplication of the conversion state object. But think about this: if a -change of the state is necessary to emit the next multibyte character -we want to have the same shift state change performed in the real -conversion.

However, the defined set of functions -is quite limited, thus the GNU C library contains a few extensions -which can help in some important situations. - - - Function: size_t mbsrtowcs (wchar_t *restrict DST, const char - **restrict SRC, size_t LEN, mbstate_t *restrict PS) - The `mbsrtowcs' function ("multibyte string restartable to wide - character string") converts an NUL terminated multibyte character - string at `*SRC' into an equivalent wide character string, - including the NUL wide character at the end. The conversion is - started using the state information from the object pointed to by - PS or from an internal object of `mbsrtowcs' if PS is a null - pointer. Before returning the state object to match the state - after the last converted character. The state is the initial - state if the terminating NUL byte is reached and converted. - - If DST is not a null pointer the result is stored in the array - pointed to by DST, otherwise the conversion result is not - available since it is stored in an internal buffer. +File: libc.info, Node: Extended Char Intro, Next: Charset Function Overview, Up: Character Set Handling - If LEN wide characters are stored in the array DST before reaching - the end of the input string the conversion stops and LEN is - returned. If DST is a null pointer LEN is never checked. +Introduction to Extended Characters +=================================== - Another reason for a premature return from the function call is if - the input string contains an invalid multibyte sequence. In this - case the global variable `errno' is set to `EILSEQ' and the - function returns `(size_t) -1'. + A variety of solutions is available to overcome the differences +between character sets with a 1:1 relation between bytes and characters +and character sets with ratios of 2:1 or 4:1. The remainder of this +section gives a few examples to help understand the design decisions +made while developing the functionality of the C library. - In all other cases the function returns the number of wide - characters converted during this call. If DST is not null - `mbsrtowcs' stores in the pointer pointed to by SRC a null pointer - (if the NUL byte in the input string was reached) or the address - of the byte following the last converted multibyte character. + A distinction we have to make right away is between internal and +external representation. "Internal representation" means the +representation used by a program while keeping the text in memory. +External representations are used when text is stored or transmitted +through some communication channel. Examples of external +representations include files waiting in a directory to be read and +parsed. - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. + Traditionally there has been no difference between the two +representations. It was equally comfortable and useful to use the same +single-byte representation internally and externally. This comfort +level decreases with more and larger character sets. - The definition of this function has one limitation which has to be -understood. The requirement that DST has to be a NUL terminated string -provides problems if one wants to convert buffers with text. A buffer -is normally no collection of NUL terminated strings but instead a -continuous collection of lines, separated by newline characters. Now -assume a function to convert one line from a buffer is needed. Since -the line is not NUL terminated the source pointer cannot directly point -into the unmodified text buffer. This means, either one inserts the NUL -byte at the appropriate place for the time of the `mbsrtowcs' function -call (which is not doable for a read-only buffer or in a multi-threaded -application) or one copies the line in an extra buffer where it can be -terminated by a NUL byte. Note that it is not in general possible to -limit the number of characters to convert by setting the parameter LEN -to any specific value. Since it is not known how many bytes each -multibyte character sequence is in length one always could do only a -guess. + One of the problems to overcome with the internal representation is +handling text that is externally encoded using different character +sets. Assume a program that reads two texts and compares them using +some metric. The comparison can be usefully done only if the texts are +internally kept in a common format. - There is still a problem with the method of NUL-terminating a line -right after the newline character which could lead to very strange -results. As said in the description of the MBSRTOWCS function above the -conversion state is guaranteed to be in the initial shift state after -processing the NUL byte at the end of the input string. But this NUL -byte is not really part of the text. I.e., the conversion state after -the newline in the original text could be something different than the -initial shift state and therefore the first character of the next line -is encoded using this state. But the state in question is never -accessible to the user since the conversion stops after the NUL byte -(which resets the state). Most stateful character sets in use today -require that the shift state after a newline is the initial state-but -this is not a strict guarantee. Therefore simply NUL terminating a -piece of a running text is not always an adequate solution and therefore -never should be used in generally used code. + For such a common format (= character set) eight bits are certainly +no longer enough. So the smallest entity will have to grow: "wide +characters" will now be used. Instead of one byte per character, two or +four will be used instead. (Three are not good to address in memory and +more than four bytes seem not to be necessary). - The generic conversion interface (*note Generic Charset Conversion::) -does not have this limitation (it simply works on buffers, not -strings), and the GNU C library contains a set of functions which take -additional parameters specifying the maximal number of bytes which are -consumed from the input string. This way the problem of `mbsrtowcs''s -example above could be solved by determining the line length and -passing this length to the function. + As shown in some other part of this manual, a completely new family +has been created of functions that can handle wide character texts in +memory. The most commonly used character sets for such internal wide +character representations are Unicode and ISO 10646 (also known as UCS +for Universal Character Set). Unicode was originally planned as a +16-bit character set; whereas, ISO 10646 was designed to be a 31-bit +large code space. The two standards are practically identical. They +have the same character repertoire and code table, but Unicode specifies +added semantics. At the moment, only characters in the first `0x10000' +code positions (the so-called Basic Multilingual Plane, BMP) have been +assigned, but the assignment of more specialized characters outside this +16-bit space is already in progress. A number of encodings have been +defined for Unicode and ISO 10646 characters: UCS-2 is a 16-bit word +that can only represent characters from the BMP, UCS-4 is a 32-bit word +than can represent any Unicode and ISO 10646 character, UTF-8 is an +ASCII compatible encoding where ASCII characters are represented by +ASCII bytes and non-ASCII characters by sequences of 2-6 non-ASCII +bytes, and finally UTF-16 is an extension of UCS-2 in which pairs of +certain UCS-2 words can be used to encode non-BMP characters up to +`0x10ffff'. - - Function: size_t wcsrtombs (char *restrict DST, const wchar_t - **restrict SRC, size_t LEN, mbstate_t *restrict PS) - The `wcsrtombs' function ("wide character string restartable to - multibyte string") converts the NUL terminated wide character - string at `*SRC' into an equivalent multibyte character string and - stores the result in the array pointed to by DST. The NUL wide - character is also converted. The conversion starts in the state - described in the object pointed to by PS or by a state object - locally to `wcsrtombs' in case PS is a null pointer. If DST is a - null pointer the conversion is performed as usual but the result - is not available. If all characters of the input string were - successfully converted and if DST is not a null pointer the - pointer pointed to by SRC gets assigned a null pointer. + To represent wide characters the `char' type is not suitable. For +this reason the ISO C standard introduces a new type that is designed +to keep one character of a wide character string. To maintain the +similarity there is also a type corresponding to `int' for those +functions that take a single wide character. - If one of the wide characters in the input string has no valid - multibyte character equivalent the conversion stops early, sets - the global variable `errno' to `EILSEQ', and returns `(size_t) -1'. + - Data type: wchar_t + This data type is used as the base type for wide character strings. + In other words, arrays of objects of this type are the equivalent + of `char[]' for multibyte character strings. The type is defined + in `stddef.h'. - Another reason for a premature stop is if DST is not a null - pointer and the next converted character would require more than - LEN bytes in total to the array DST. In this case (and if DEST is - not a null pointer) the pointer pointed to by SRC is assigned a - value pointing to the wide character right after the last one - successfully converted. + The ISO C90 standard, where `wchar_t' was introduced, does not say + anything specific about the representation. It only requires that + this type is capable of storing all elements of the basic + character set. Therefore it would be legitimate to define + `wchar_t' as `char', which might make sense for embedded systems. - Except in the case of an encoding error the return value of the - function is the number of bytes in all the multibyte character - sequences stored in DST. Before returning the state in the object - pointed to by PS (or the internal object in case PS is a null - pointer) is updated to reflect the state after the last - conversion. The state is the initial shift state in case the - terminating NUL wide character was converted. + But for GNU systems `wchar_t' is always 32 bits wide and, + therefore, capable of representing all UCS-4 values and, + therefore, covering all of ISO 10646. Some Unix systems define + `wchar_t' as a 16-bit type and thereby follow Unicode very + strictly. This definition is perfectly fine with the standard, + but it also means that to represent all characters from Unicode + and ISO 10646 one has to use UTF-16 surrogate characters, which is + in fact a multi-wide-character encoding. But resorting to + multi-wide-character encoding contradicts the purpose of the + `wchar_t' type. - This function was introduced in Amendment 1 to ISO C90 and is - declared in `wchar.h'. + - Data type: wint_t + `wint_t' is a data type used for parameters and variables that + contain a single wide character. As the name suggests this type + is the equivalent of `int' when using the normal `char' strings. + The types `wchar_t' and `wint_t' often have the same + representation if their size is 32 bits wide but if `wchar_t' is + defined as `char' the type `wint_t' must be defined as `int' due + to the parameter promotion. - The restriction mentions above for the `mbsrtowcs' function applies -also here. There is no possibility to directly control the number of -input characters. One has to place the NUL wide character at the -correct place or control the consumed input indirectly via the available -output array size (the LEN parameter). + This type is defined in `wchar.h' and was introduced in + Amendment 1 to ISO C90. - - Function: size_t mbsnrtowcs (wchar_t *restrict DST, const char - **restrict SRC, size_t NMC, size_t LEN, mbstate_t *restrict - PS) - The `mbsnrtowcs' function is very similar to the `mbsrtowcs' - function. All the parameters are the same except for NMC which is - new. The return value is the same as for `mbsrtowcs'. + As there are for the `char' data type macros are available for +specifying the minimum and maximum value representable in an object of +type `wchar_t'. - This new parameter specifies how many bytes at most can be used - from the multibyte character string. I.e., the multibyte - character string `*SRC' need not be NUL terminated. But if a NUL - byte is found within the NMC first bytes of the string the - conversion stops here. + - Macro: wint_t WCHAR_MIN + The macro `WCHAR_MIN' evaluates to the minimum value representable + by an object of type `wint_t'. - This function is a GNU extensions. It is meant to work around the - problems mentioned above. Now it is possible to convert buffer - with multibyte character text piece for piece without having to - care about inserting NUL bytes and the effect of NUL bytes on the - conversion state. + This macro was introduced in Amendment 1 to ISO C90. - A function to convert a multibyte string into a wide character string -and display it could be written like this (this is not a really useful -example): + - Macro: wint_t WCHAR_MAX + The macro `WCHAR_MAX' evaluates to the maximum value representable + by an object of type `wint_t'. - void - showmbs (const char *src, FILE *fp) - { - mbstate_t state; - int cnt = 0; - memset (&state, '\0', sizeof (state)); - while (1) - { - wchar_t linebuf[100]; - const char *endp = strchr (src, '\n'); - size_t n; - - /* Exit if there is no more line. */ - if (endp == NULL) - break; - - n = mbsnrtowcs (linebuf, &src, endp - src, 99, &state); - linebuf[n] = L'\0'; - fprintf (fp, "line %d: \"%S\"\n", linebuf); - } - } + This macro was introduced in Amendment 1 to ISO C90. - There is no problem with the state after a call to `mbsnrtowcs'. -Since we don't insert characters in the strings which were not in there -right from the beginning and we use STATE only for the conversion of -the given buffer there is no problem with altering the state. + Another special wide character value is the equivalent to `EOF'. - - Function: size_t wcsnrtombs (char *restrict DST, const wchar_t - **restrict SRC, size_t NWC, size_t LEN, mbstate_t *restrict - PS) - The `wcsnrtombs' function implements the conversion from wide - character strings to multibyte character strings.

Because each single wide character consists +of more than one byte, they are effected by byte-ordering. Thus, +machines with different endianesses would see different values when +accessing the same data. This byte ordering concern also applies for +communication protocols that are all byte-based and, thereforet require +that the sender has to decide about splitting the wide character in +bytes. A last (but not least important) point is that wide characters +often require more storage space than a customized byte-oriented +character set. - -File: libc.info, Node: Non-reentrant Conversion, Next: Generic Charset Conversion, Prev: Restartable multibyte conversion, Up: Character Set Handling + For all the above reasons, an external encoding that is different +from the internal encoding is often used if the latter is UCS-2 or +UCS-4. The external encoding is byte-based and can be chosen +appropriately for the environment and for the texts to be handled. A +variety of different character sets can be used for this external +encoding (information that will not be exhaustively presented +here-instead, a description of the major groups will suffice). All of +the ASCII-based character sets fulfill one requirement: they are +"filesystem safe." This means that the character `'/'' is used in the +encoding _only_ to represent itself. Things are a bit different for +character sets like EBCDIC (Extended Binary Coded Decimal Interchange +Code, a character set family used by IBM), but if the operation system +does not understand EBCDIC directly the parameters-to-system calls have +to be converted first anyhow. -Non-reentrant Conversion Function -================================= + * The simplest character sets are single-byte character sets. There + can be only up to 256 characters (for 8 bit character sets), which + is not sufficient to cover all languages but might be sufficient + to handle a specific text. Handling of a 8 bit character sets is + simple. This is not true for other kinds presented later, and + therefore, the application one uses might require the use of 8 bit + character sets. - The functions described in the last chapter are defined in -Amendment 1 to ISO C90. But the original ISO C90 standard also -contained functions for character set conversion. The reason that they -are not described in the first place is that they are almost entirely -useless. + * The ISO 2022 standard defines a mechanism for extended character + sets where one character _can_ be represented by more than one + byte. This is achieved by associating a state with the text. + Characters that can be used to change the state can be embedded in + the text. Each byte in the text might have a different + interpretation in each state. The state might even influence + whether a given byte stands for a character on its own or whether + it has to be combined with some more bytes. - The problem is that all the functions for conversion defined in -ISO C90 use a local state. This implies that multiple conversions at -the same time (not only when using threads) cannot be done, and that you -cannot first convert single characters and then strings since you cannot -tell the conversion functions which state to use. + In most uses of ISO 2022 the defined character sets do not allow + state changes that cover more than the next character. This has + the big advantage that whenever one can identify the beginning of + the byte sequence of a character one can interpret a text + correctly. Examples of character sets using this policy are the + various EUC character sets (used by Sun's operations systems, + EUC-JP, EUC-KR, EUC-TW, and EUC-CN) or Shift_JIS (SJIS, a Japanese + encoding). - These functions are therefore usable only in a very limited set of -situations. One must complete converting the entire string before -starting a new one and each string/text must be converted with the same -function (there is no problem with the library itself; it is guaranteed -that no library function changes the state of any of these functions). -*For the above reasons it is highly requested that the functions from -the last section are used in place of non-reentrant conversion -functions.* + But there are also character sets using a state that is valid for + more than one character and has to be changed by another byte + sequence. Examples for this are ISO-2022-JP, ISO-2022-KR, and + ISO-2022-CN. -* Menu: + * Early attempts to fix 8 bit character sets for other languages + using the Roman alphabet lead to character sets like ISO 6937. + Here bytes representing characters like the acute accent do not + produce output themselves: one has to combine them with other + characters to get the desired result. For example, the byte + sequence `0xc2 0x61' (non-spacing acute accent, followed by + lower-case `a') to get the "small a with acute" character. To + get the acute accent character on its own, one has to write `0xc2 + 0x20' (the non-spacing acute followed by a space). -* Non-reentrant Character Conversion:: Non-reentrant Conversion of Single - Characters. -* Non-reentrant String Conversion:: Non-reentrant Conversion of Strings. -* Shift State:: States in Non-reentrant Functions. + Character sets like ISO 6937 are used in some embedded systems such + as teletex. - -File: libc.info, Node: Non-reentrant Character Conversion, Next: Non-reentrant String Conversion, Up: Non-reentrant Conversion + * Instead of converting the Unicode or ISO 10646 text used + internally, it is often also sufficient to simply use an encoding + different than UCS-2/UCS-4.

This encoding is able to + represent all of ISO 10646 31 bits in a byte string of length one + to six. -Non-reentrant Conversion of Single Characters ---------------------------------------------- + There were a few other attempts to encode ISO 10646 such as UTF-7, + but UTF-8 is today the only encoding that should be used. In + fact, with any luck UTF-8 will soon be the only external encoding + that has to be supported.

Methods like the Unicode compression + scheme can alleviate these problems. - - Function: int mbtowc (wchar_t *restrict RESULT, const char *restrict - STRING, size_t SIZE) - The `mbtowc' ("multibyte to wide character") function when called - with non-null STRING converts the first multibyte character - beginning at STRING to its corresponding wide character code. It - stores the result in `*RESULT'. + The question remaining is: how to select the character set or +encoding to use. The answer: you cannot decide about it yourself, it +is decided by the developers of the system or the majority of the +users. Since the goal is interoperability one has to use whatever the +other people one works with use. If there are no constraints, the +selection is based on the requirements the expected circle of users +will have. In other words, if a project is expected to be used in +only, say, Russia it is fine to use KOI8-R or a similar character set. +But if at the same time people from, say, Greece are participating one +should use a character set that allows all people to collaborate. - `mbtowc' never examines more than SIZE bytes. (The idea is to - supply for SIZE the number of bytes of data you have in hand.) + The most widely useful solution seems to be: go with the most general +character set, namely ISO 10646. Use UTF-8 as the external encoding +and problems about users not being able to use their own language +adequately are a thing of the past. - `mbtowc' with non-null STRING distinguishes three possibilities: - the first SIZE bytes at STRING start with valid multibyte - character, they start with an invalid byte sequence or just part - of a character, or STRING points to an empty string (a null - character). + One final comment about the choice of the wide character +representation is necessary at this point. We have said above that the +natural choice is using Unicode or ISO 10646. This is not required, +but at least encouraged, by the ISO C standard. The standard defines +at least a macro `__STDC_ISO_10646__' that is only defined on systems +where the `wchar_t' type encodes ISO 10646 characters. If this symbol +is not defined one should avoid making assumptions about the wide +character representation. If the programmer uses only the functions +provided by the C library to handle wide character strings there should +be no compatibility problems with other systems. - For a valid multibyte character, `mbtowc' converts it to a wide - character and stores that in `*RESULT', and returns the number of - bytes in that character (always at least 1, and never more than - SIZE). + +File: libc.info, Node: Charset Function Overview, Next: Restartable multibyte conversion, Prev: Extended Char Intro, Up: Character Set Handling - For an invalid byte sequence, `mbtowc' returns -1.

It was introduced in + Amendment 1 to ISO C90. -States in Non-reentrant Functions ---------------------------------- + To use objects of type `mbstate_t' the programmer has to define such +objects (normally as local variables on the stack) and pass a pointer to +the object to the conversion functions. This way the conversion +function can update the object if the current multibyte character set +is stateful. - In some multibyte character codes, the _meaning_ of any particular -byte sequence is not fixed; it depends on what other sequences have come -earlier in the same string. Typically there are just a few sequences -that can change the meaning of other sequences; these few are called -"shift sequences" and we say that they set the "shift state" for other -sequences that follow. + There is no specific function or initializer to put the state object +in any specific state. The rules are that the object should always +represent the initial state before the first use, and this is achieved +by clearing the whole variable with code such as follows: - To illustrate shift state and shift sequences, suppose we decide that -the sequence `0200' (just one byte) enters Japanese mode, in which -pairs of bytes in the range from `0240' to `0377' are single -characters, while `0201' enters Latin-1 mode, in which single bytes in -the range from `0240' to `0377' are characters, and interpreted -according to the ISO Latin-1 character set. This is a multibyte code -which has two alternative shift states ("Japanese mode" and "Latin-1 -mode"), and two shift sequences that specify particular shift states. + { + mbstate_t state; + memset (&state, '\0', sizeof (state)); + /* from now on STATE can be used. */ + ... + } - When the multibyte character code in use has shift states, then -`mblen', `mbtowc' and `wctomb' must maintain and update the current -shift state as they scan the string. To make this work properly, you -must follow these rules: + When using the conversion functions to generate output it is often +necessary to test whether the current state corresponds to the initial +state. This is necessary, for example, to decide whether to emit +escape sequences to set the state to the initial state at certain +sequence points. Communication protocols often require this. - * Before starting to scan a string, call the function with a null - pointer for the multibyte character address--for example, `mblen - (NULL, 0)'. This initializes the shift state to its standard - initial value. + - Function: int mbsinit (const mbstate_t *PS) + The `mbsinit' function determines whether the state object pointed + to by PS is in the initial state. If PS is a null pointer or the + object is in the initial state the return value is nonzero. + Otherwise it is zero. - * Scan the string one character at a time, in order. Do not "back - up" and rescan characters already scanned, and do not intersperse - the processing of different strings. + `mbsinit' was introduced in Amendment 1 to ISO C90 and is declared + in `wchar.h'. - Here is an example of using `mblen' following these rules: + Code using `mbsinit' often looks similar to this: - void - scan_string (char *s) { - int length = strlen (s); - - /* Initialize shift state. */ - mblen (NULL, 0); - - while (1) + mbstate_t state; + memset (&state, '\0', sizeof (state)); + /* Use STATE. */ + ... + if (! mbsinit (&state)) { - int thischar = mblen (s, length); - /* Deal with end of string and invalid characters. */ - if (thischar == 0) - break; - if (thischar == -1) - { - error ("invalid multibyte character"); - break; - } - /* Advance past this character. */ - s += thischar; - length -= thischar; + /* Emit code to return to initial state. */ + const wchar_t empty[] = L""; + const wchar_t *srcp = empty; + wcsrtombs (outbuf, &srcp, outbuflen, &state); } + ... } - The functions `mblen', `mbtowc' and `wctomb' are not reentrant when -using a multibyte code that uses a shift state. However, no other -library functions call these functions, so you don't have to worry that -the shift state will be changed mysteriously. + The code to emit the escape sequence to get back to the initial +state is interesting. The `wcsrtombs' function can be used to +determine the necessary output code (*note Converting Strings::). +Please note that on GNU systems it is not necessary to perform this +extra action for the conversion from multibyte text to wide character +text since the wide character encoding is not stateful.

One would have to select the source character set as the - multibyte encoding, convert the text into a `wchar_t' text, select - the destination character set as the multibyte encoding and - convert the wide character text to the multibyte (= destination) - character set. +File: libc.info, Node: Converting a Character, Next: Converting Strings, Prev: Keeping the state, Up: Restartable multibyte conversion - Even if this is possible (which is not guaranteed) it is a very - tiring work. Plus it suffers from the other two raised points - even more due to the steady changing of the locale. +Converting Single Characters +---------------------------- - The XPG2 standard defines a completely new set of functions which has -none of these limitations. They are not at all coupled to the selected -locales and they but no constraints on the character sets selected for -source and destination. Only the set of available conversions is -limiting them. The standard does not specify that any conversion at all -must be available. It is a measure of the quality of the -implementation. + The most fundamental of the conversion functions are those dealing +with single characters. Please note that this does not always mean +single bytes. But since there is very often a subset of the multibyte +character set that consists of single byte sequences, there are +functions to help with converting bytes. Frequently, ASCII is a subpart +of the multibyte character set. In such a scenario, each ASCII +character stands for itself, and all other characters have at least a +first byte that is beyond the range 0 to 127. - In the following text first the interface to `iconv', the conversion -function, will be described.

Most characters are either entirely single-byte character +sets or they are extension to ASCII. But then it is possible to write +code like this (not that this specific example is very useful): - This set of functions follows the traditional cycle of using a -resource: open-use-close. The interface consists of three functions, -each of which implement one step. + wchar_t * + itow (unsigned long int val) + { + static wchar_t buf[30]; + wchar_t *wcp = &buf[29]; + *wcp = L'\0'; + while (val != 0) + { + *--wcp = btowc ('0' + val % 10); + val /= 10; + } + if (wcp == &buf[29]) + *--wcp = L'0'; + return wcp; + } - Before the interfaces are described it is necessary to introduce a -datatype. Just like other open-use-close interface the functions -introduced here work using a handles and the `iconv.h' header defines a -special type for the handles used. + Why is it necessary to use such a complicated implementation and not +simply cast `'0' + val % 10' to a wide character? The answer is that +there is no guarantee that one can perform this kind of arithmetic on +the character of the character set used for `wchar_t' representation. +In other situations the bytes are not constant at compile time and so +the compiler cannot do the work. In situations like this it is +necessary `btowc'. - - Data Type: iconv_t - This data type is an abstract type defined in `iconv.h'. The user - must not assume anything about the definition of this type, it - must be completely opaque. +There also is a function for the conversion in the other direction. - Objects of this type can get assigned handles for the conversions - using the `iconv' functions. The objects themselves need not be - freed but the conversions for which the handles stand for have to. + - Function: int wctob (wint_t C) + The `wctob' function ("wide character to byte") takes as the + parameter a valid wide character. If the multibyte representation + for this character in the initial state is exactly one byte long, + the return value of this function is this character. Otherwise + the return value is `EOF'. -The first step is the function to create a handle. + `wctob' was introduced in Amendment 1 to ISO C90 and is declared + in `wchar.h'. - - Function: iconv_t iconv_open (const char *TOCODE, const char - *FROMCODE) - The `iconv_open' function has to be used before starting a - conversion. The two parameters this function takes determine the - source and destination character set for the conversion and if the - implementation has the possibility to perform such a conversion the - function returns a handle. + There are more general functions to convert single character from +multibyte representation to wide characters and vice versa. These +functions pose no limit on the length of the multibyte representation +and they also do not require it to be in the initial state. - If the wanted conversion is not available the function returns - `(iconv_t) -1'. In this case the global variable `errno' can have - the following values: + - Function: size_t mbrtowc (wchar_t *restrict PWC, const char + *restrict S, size_t N, mbstate_t *restrict PS) + The `mbrtowc' function ("multibyte restartable to wide character") + converts the next multibyte character in the string pointed to by + S into a wide character and stores it in the wide character string + pointed to by PWC. The conversion is performed according to the + locale currently selected for the `LC_CTYPE' category. If the + conversion for the character set used in the locale requires a + state, the multibyte string is interpreted in the state + represented by the object pointed to by PS. If PS is a null + pointer, a static, internal state variable used only by the + `mbrtowc' function is used. - `EMFILE' - The process already has `OPEN_MAX' file descriptors open. + If the next multibyte character corresponds to the NUL wide + character, the return value of the function is 0 and the state + object is afterwards in the initial state. If the next N or fewer + bytes form a correct multibyte character, the return value is the + number of bytes starting from S that form the multibyte character. + The conversion state is updated according to the bytes consumed + in the conversion. In both cases the wide character (either the + `L'\0'' or the one found in the conversion) is stored in the + string pointed to by PWC if PWC is not null. - `ENFILE' - The system limit of open file is reached. + If the first N bytes of the multibyte string possibly form a valid + multibyte character but there are more than N bytes needed to + complete it, the return value of the function is `(size_t) -2' and + no value is stored. Please note that this can happen even if N + has a value greater than or equal to `MB_CUR_MAX' since the input + might contain redundant shift sequences. - `ENOMEM' - Not enough memory to carry out the operation. + If the first `n' bytes of the multibyte string cannot possibly form + a valid multibyte character, no value is stored, the global + variable `errno' is set to the value `EILSEQ', and the function + returns `(size_t) -1'. The conversion state is afterwards + undefined. - `EINVAL' - The conversion from FROMCODE to TOCODE is not supported. + `mbrtowc' was introduced in Amendment 1 to ISO C90 and is declared + in `wchar.h'. - It is not possible to use the same descriptor in different threads - to perform independent conversions. Within the data structures - associated with the descriptor there is information about the - conversion state. This must not be messed up by using it in - different conversions. + Use of `mbrtowc' is straightforward. A function that copies a +multibyte string into a wide character string while at the same time +converting all lowercase characters into uppercase could look like this +(this is not the final version, just an example; it has no error +checking, and sometimes leaks memory): - An `iconv' descriptor is like a file descriptor as for every use a - new descriptor must be created. The descriptor does not stand for - all of the conversions from FROMSET to TOSET. + wchar_t * + mbstouwcs (const char *s) + { + size_t len = strlen (s); + wchar_t *result = malloc ((len + 1) * sizeof (wchar_t)); + wchar_t *wcp = result; + wchar_t tmp[1]; + mbstate_t state; + size_t nbytes; + + memset (&state, '\0', sizeof (state)); + while ((nbytes = mbrtowc (tmp, s, len, &state)) > 0) + { + if (nbytes >= (size_t) -2) + /* Invalid input string. */ + return NULL; + *result++ = towupper (tmp[0]); + len -= nbytes; + s += nbytes; + } + return result; + } - The GNU C library implementation of `iconv_open' has one - significant extension to other implementations. To ease the - extension of the set of available conversions the implementation - allows storing the necessary files with data and code in - arbitrarily many directories. How this extension has to be - written will be explained below (*note glibc iconv - Implementation::). Here it is only important to say that all - directories mentioned in the `GCONV_PATH' environment variable are - considered if they contain a file `gconv-modules'. These - directories need not necessarily be created by the system - administrator. In fact, this extension is introduced to help users - writing and using their own, new conversions. Of course this does - not work for security reasons in SUID binaries; in this case only - the system directory is considered and this normally is - `PREFIX/lib/gconv'. The `GCONV_PATH' environment variable is - examined exactly once at the first call of the `iconv_open' - function. Later modifications of the variable have no effect. + The use of `mbrtowc' should be clear. A single wide character is +stored in `TMP[0]', and the number of consumed bytes is stored in the +variable NBYTES. If the conversion is successful, the uppercase +variant of the wide character is stored in the RESULT array and the +pointer to the input string and the number of available bytes is +adjusted. - This function got introduced early in the X/Open Portability Guide, - version 2. It is supported by all commercial Unices as it is - required for the Unix branding. However, the quality and - completeness of the implementation varies widely. The function is - declared in `iconv.h'. + The only non-obvious thing about `mbrtowc' might be the way memory +is allocated for the result. The above code uses the fact that there +can never be more wide characters in the converted results than there +are bytes in the multibyte input string. This method yields a +pessimistic guess about the size of the result, and if many wide +character strings have to be constructed this way or if the strings are +long, the extra memory required to be allocated because the input +string contains multibyte characters might be significant. The +allocated memory block can be resized to the correct size before +returning it, but a better solution might be to allocate just the right +amount of space for the result right away. Unfortunately there is no +function to compute the length of the wide character string directly +from the multibyte string. There is, however, a function that does +part of the work. - The `iconv' implementation can associate large data structure with -the handle returned by `iconv_open'. Therefore it is crucial to free -all the resources once all conversions are carried out and the -conversion is not needed anymore. + - Function: size_t mbrlen (const char *restrict S, size_t N, mbstate_t + *PS) + The `mbrlen' function ("multibyte restartable length") computes + the number of at most N bytes starting at S, which form the next + valid and complete multibyte character. - - Function: int iconv_close (iconv_t CD) - The `iconv_close' function frees all resources associated with the - handle CD which must have been returned by a successful call to - the `iconv_open' function. + If the next multibyte character corresponds to the NUL wide + character, the return value is 0. If the next N bytes form a valid + multibyte character, the number of bytes belonging to this + multibyte character byte sequence is returned. - If the function call was successful the return value is 0. - Otherwise it is -1 and `errno' is set appropriately. Defined - error are: + If the the first N bytes possibly form a valid multibyte character + but the character is incomplete, the return value is `(size_t) + -2'. Otherwise the multibyte character sequence is invalid and + the return value is `(size_t) -1'. - `EBADF' - The conversion descriptor is invalid. + The multibyte sequence is interpreted in the state represented by + the object pointed to by PS. If PS is a null pointer, a state + object local to `mbrlen' is used. - This function was introduced together with the rest of the `iconv' - functions in XPG2 and it is declared in `iconv.h'. + `mbrlen' was introduced in Amendment 1 to ISO C90 and is declared + in `wchar.h'. - The standard defines only one actual conversion function. This has -therefore the most general interface: it allows conversion from one -buffer to another. Conversion from a file to a buffer, vice versa, or -even file to file can be implemented on top of it. + The attentive reader now will note that `mbrlen' can be implemented +as - - Function: size_t iconv (iconv_t CD, char **INBUF, size_t - *INBYTESLEFT, char **OUTBUF, size_t *OUTBYTESLEFT) - The `iconv' function converts the text in the input buffer - according to the rules associated with the descriptor CD and - stores the result in the output buffer. It is possible to call the - function for the same text several times in a row since for - stateful character sets the necessary state information is kept in - the data structures associated with the descriptor. + mbrtowc (NULL, s, n, ps != NULL ? ps : &internal) - The input buffer is specified by `*INBUF' and it contains - `*INBYTESLEFT' bytes. The extra indirection is necessary for - communicating the used input back to the caller (see below). It is - important to note that the buffer pointer is of type `char' and the - length is measured in bytes even if the input text is encoded in - wide characters. + This is true and in fact is mentioned in the official specification. +How can this function be used to determine the length of the wide +character string created from a multibyte character string? It is not +directly usable, but we can define a function `mbslen' using it: - The output buffer is specified in a similar way. `*OUTBUF' points - to the beginning of the buffer with at least `*OUTBYTESLEFT' bytes - room for the result. The buffer pointer again is of type `char' - and the length is measured in bytes. If OUTBUF or `*OUTBUF' is a - null pointer the conversion is performed but no output is - available. + size_t + mbslen (const char *s) + { + mbstate_t state; + size_t result = 0; + size_t nbytes; + memset (&state, '\0', sizeof (state)); + while ((nbytes = mbrlen (s, MB_LEN_MAX, &state)) > 0) + { + if (nbytes >= (size_t) -2) + /* Something is wrong. */ + return (size_t) -1; + s += nbytes; + ++result; + } + return result; + } - If INBUF is a null pointer the `iconv' function performs the - necessary action to put the state of the conversion into the - initial state. This is obviously a no-op for non-stateful - encodings, but if the encoding has a state such a function call - might put some byte sequences in the output buffer which perform - the necessary state changes. The next call with INBUF not being a - null pointer then simply goes on from the initial state. It is - important that the programmer never makes any assumption on - whether the conversion has to deal with states or not. Even if - the input and output character sets are not stateful the - implementation might still have to keep states. This is due to the - implementation chosen for the GNU C library as it is described - below. Therefore an `iconv' call to reset the state should always - be performed if some protocol requires this for the output text. + This function simply calls `mbrlen' for each multibyte character in +the string and counts the number of function calls. Please note that +we here use `MB_LEN_MAX' as the size argument in the `mbrlen' call. +This is acceptable since a) this value is larger then the length of the +longest multibyte character sequence and b) we know that the string S +ends with a NUL byte, which cannot be part of any other multibyte +character sequence but the one representing the NUL wide character. +Therefore, the `mbrlen' function will never read invalid memory. - The conversion stops for three reasons. The first is that all - characters from the input buffer are converted. This actually can - mean two things: really all bytes from the input buffer are - consumed or there are some bytes at the end of the buffer which - possibly can form a complete character but the input is - incomplete. The second reason for a stop is when the output - buffer is full. And the third reason is that the input contains - invalid characters. + Now that this function is available (just to make this clear, this +function is _not_ part of the GNU C library) we can compute the number +of wide character required to store the converted multibyte character +string S using - In all these cases the buffer pointers after the last successful - conversion, for input and output buffer, are stored in INBUF and - OUTBUF and the available room in each buffer is stored in - INBYTESLEFT and OUTBYTESLEFT. + wcs_bytes = (mbslen (s) + 1) * sizeof (wchar_t); - Since the character sets selected in the `iconv_open' call can be - almost arbitrary there can be situations where the input buffer - contains valid characters which have no identical representation - in the output character set. The behavior in this situation is - undefined. The _current_ behavior of the GNU C library in this - situation is to return with an error immediately. This certainly - is not the most desirable solution. Therefore future versions - will provide better ones but they are not yet finished. + Please note that the `mbslen' function is quite inefficient. The +implementation of `mbstouwcs' with `mbslen' would have to perform the +conversion of the multibyte character input string twice, and this +conversion might be quite expensive. So it is necessary to think about +the consequences of using the easier but imprecise method before doing +the work twice. - If all input from the input buffer is successfully converted and - stored in the output buffer the function returns the number of - non-reversible conversions performed. In all other cases the - return value is `(size_t) -1' and `errno' is set appropriately. - In this case the value pointed to by INBYTESLEFT is nonzero. + - Function: size_t wcrtomb (char *restrict S, wchar_t WC, mbstate_t + *restrict PS) + The `wcrtomb' function ("wide character restartable to multibyte") + converts a single wide character into a multibyte string + corresponding to that wide character. - `EILSEQ' - The conversion stopped because of an invalid byte sequence in - the input. After the call `*INBUF' points at the first byte - of the invalid byte sequence. + If S is a null pointer, the function resets the state stored in + the objects pointed to by PS (or the internal `mbstate_t' object) + to the initial state. This can also be achieved by a call like + this: - `E2BIG' - The conversion stopped because it ran out of space in the - output buffer. + wcrtombs (temp_buf, L'\0', ps) - `EINVAL' - The conversion stopped because of an incomplete byte sequence - at the end of the input buffer. + since, if S is a null pointer, `wcrtomb' performs as if it writes + into an internal buffer, which is guaranteed to be large enough. - `EBADF' - The CD argument is invalid. + If WC is the NUL wide character, `wcrtomb' emits, if necessary, a + shift sequence to get the state PS into the initial state followed + by a single NUL byte, which is stored in the string S. - This function was introduced in the XPG2 standard and is declared - in the `iconv.h' header. + Otherwise a byte sequence (possibly including shift sequences) is + written into the string S. This only happens if WC is a valid wide + character (i.e., it has a multibyte representation in the + character set selected by locale of the `LC_CTYPE' category). If + WC is no valid wide character, nothing is stored in the strings S, + `errno' is set to `EILSEQ', the conversion state in PS is + undefined and the return value is `(size_t) -1'. - The definition of the `iconv' function is quite good overall. It -provides quite flexible functionality. The only problems lie in the -boundary cases which are incomplete byte sequences at the end of the -input buffer and invalid input. A third problem, which is not really a -design problem, is the way conversions are selected. The standard does -not say anything about the legitimate names, a minimal set of available -conversions. We will see how this negatively impacts other -implementations, as is demonstrated below. + If no error occurred the function returns the number of bytes + stored in the string S. This includes all bytes representing shift + sequences. - -File: libc.info, Node: iconv Examples, Next: Other iconv Implementations, Prev: Generic Conversion Interface, Up: Generic Charset Conversion + One word about the interface of the function: there is no parameter + specifying the length of the array S. Instead the function + assumes that there are at least `MB_CUR_MAX' bytes available since + this is the maximum length of any byte sequence representing a + single character. So the caller has to make sure that there is + enough space available, otherwise buffer overruns can occur. -A complete `iconv' example --------------------------- + `wcrtomb' was introduced in Amendment 1 to ISO C90 and is declared + in `wchar.h'. - The example below features a solution for a common problem. Given -that one knows the internal encoding used by the system for `wchar_t' -strings one often is in the position to read text from a file and store -it in wide character buffers. One can do this using `mbsrtowcs' but -then we run into the problems discussed above. + Using `wcrtomb' is as easy as using `mbrtowc'. The following +example appends a wide character string to a multibyte character string. +Again, the code is not really useful (or correct), it is simply here to +demonstrate the use and some problems. - int - file2wcs (int fd, const char *charset, wchar_t *outbuf, size_t avail) + char * + mbscatwcs (char *s, size_t len, const wchar_t *ws) { - char inbuf[BUFSIZ]; - size_t insize = 0; - char *wrptr = (char *) outbuf; - int result = 0; - iconv_t cd; - - cd = iconv_open ("WCHAR_T", charset); - if (cd == (iconv_t) -1) - { - /* Something went wrong. */ - if (errno == EINVAL) - error (0, 0, "conversion from '%s' to wchar_t not available", - charset); - else - perror ("iconv_open"); - - /* Terminate the output string. */ - *outbuf = L'\0'; - - return -1; - } - - while (avail > 0) + mbstate_t state; + /* Find the end of the existing string. */ + char *wp = strchr (s, '\0'); + len -= wp - s; + memset (&state, '\0', sizeof (state)); + do { - size_t nread; - size_t nconv; - char *inptr = inbuf; - - /* Read more input. */ - nread = read (fd, inbuf + insize, sizeof (inbuf) - insize); - if (nread == 0) - { - /* When we come here the file is completely read. - This still could mean there are some unused - characters in the `inbuf'. Put them back. */ - if (lseek (fd, -insize, SEEK_CUR) == -1) - result = -1; - - /* Now write out the byte sequence to get into the - initial state if this is necessary. */ - iconv (cd, NULL, NULL, &wrptr, &avail); - - break; - } - insize += nread; - - /* Do the conversion. */ - nconv = iconv (cd, &inptr, &insize, &wrptr, &avail); - if (nconv == (size_t) -1) + size_t nbytes; + if (len < MB_CUR_LEN) { - /* Not everything went right. It might only be - an unfinished byte sequence at the end of the - buffer. Or it is a real problem. */ - if (errno == EINVAL) - /* This is harmless. Simply move the unused - bytes to the beginning of the buffer so that - they can be used in the next round. */ - memmove (inbuf, inptr, insize); - else - { - /* It is a real problem. Maybe we ran out of - space in the output buffer or we have invalid - input. In any case back the file pointer to - the position of the last processed byte. */ - lseek (fd, -insize, SEEK_CUR); - result = -1; - break; - } + /* We cannot guarantee that the next + character fits into the buffer, so + return an error. */ + errno = E2BIG; + return NULL; } + nbytes = wcrtomb (wp, *ws, &state); + if (nbytes == (size_t) -1) + /* Error in the conversion. */ + return NULL; + len -= nbytes; + wp += nbytes; } - - /* Terminate the output string. */ - if (avail >= sizeof (wchar_t)) - *((wchar_t *) wrptr) = L'\0'; - - if (iconv_close (cd) != 0) - perror ("iconv_close"); - - return (wchar_t *) wrptr - outbuf; + while (*ws++ != L'\0'); + return s; } - This example shows the most important aspects of using the `iconv' -functions. It shows how successive calls to `iconv' can be used to -convert large amounts of text. The user does not have to care about -stateful encodings as the functions take care of everything. + First the function has to find the end of the string currently in the +array S. The `strchr' call does this very efficiently since a +requirement for multibyte character representations is that the NUL byte +is never used except to represent itself (and in this context, the end +of the string). - An interesting point is the case where `iconv' return an error and -`errno' is set to `EINVAL'. This is not really an error in the -transformation. It can happen whenever the input character set -contains byte sequences of more than one byte for some character and -texts are not processed in one piece. In this case there is a chance -that a multibyte sequence is cut. The caller than can simply read the -remainder of the takes and feed the offending bytes together with new -character from the input to `iconv' and continue the work. The -internal state kept in the descriptor is _not_ unspecified after such -an event as it is the case with the conversion functions from the ISO C -standard. + After initializing the state object the loop is entered where the +first task is to make sure there is enough room in the array S. We +abort if there are not at least `MB_CUR_LEN' bytes available. This is +not always optimal but we have no other choice. We might have less +than `MB_CUR_LEN' bytes available but the next multibyte character +might also be only one byte long. At the time the `wcrtomb' call +returns it is too late to decide whether the buffer was large enough. +If this solution is unsuitable, there is a very slow but more accurate +solution. - The example also shows the problem of using wide character strings -with `iconv'. As explained in the description of the `iconv' function -above the function always takes a pointer to a `char' array and the -available space is measured in bytes. In the example the output buffer -is a wide character buffer. Therefore we use a local variable WRPTR of -type `char *' which is used in the `iconv' calls. + ... + if (len < MB_CUR_LEN) + { + mbstate_t temp_state; + memcpy (&temp_state, &state, sizeof (state)); + if (wcrtomb (NULL, *ws, &temp_state) > len) + { + /* We cannot guarantee that the next + character fits into the buffer, so + return an error. */ + errno = E2BIG; + return NULL; + } + } + ... - This looks rather innocent but can lead to problems on platforms -which have tight restriction on alignment. Therefore the caller of -`iconv' has to make sure that the pointers passed are suitable for -access of characters from the appropriate character set. Since in the -above case the input parameter to the function is a `wchar_t' pointer -this is the case (unless the user violates alignment when computing the -parameter). But in other situations, especially when writing generic -functions where one does not know what type of character set one uses -and therefore treats text as a sequence of bytes, it might become -tricky. + Here we perform the conversion that might overflow the buffer so that +we are afterwards in the position to make an exact decision about the +buffer size. Please note the `NULL' argument for the destination +buffer in the new `wcrtomb' call; since we are not interested in the +converted text at this point, this is a nice way to express this. The +most unusual thing about this piece of code certainly is the duplication +of the conversion state object, but if a change of the state is +necessary to emit the next multibyte character, we want to have the +same shift state change performed in the real conversion. Therefore, +we have to preserve the initial shift state information. + + There are certainly many more and even better solutions to this +problem. This example is only provided for educational purposes.  -File: libc.info, Node: Other iconv Implementations, Next: glibc iconv Implementation, Prev: iconv Examples, Up: Generic Charset Conversion +File: libc.info, Node: Converting Strings, Next: Multibyte Conversion Example, Prev: Converting a Character, Up: Restartable multibyte conversion -Some Details about other `iconv' Implementations ------------------------------------------------- +Converting Multibyte and Wide Character Strings +----------------------------------------------- - This is not really the place to discuss the `iconv' implementation -of other systems but it is necessary to know a bit about them to write -portable programs. The above mentioned problems with the specification -of the `iconv' functions can lead to portability issues. + The functions described in the previous section only convert a single +character at a time. Most operations to be performed in real-world +programs include strings and therefore the ISO C standard also defines +conversions on entire strings. However, the defined set of functions +is quite limited; therefore, the GNU C library contains a few +extensions that can help in some important situations. - The first thing to notice is that due to the large number of -character sets in use it is certainly not practical to encode the -conversions directly in the C library. Therefore the conversion -information must come from files outside the C library. This is -usually done in one or both of the following ways: + - Function: size_t mbsrtowcs (wchar_t *restrict DST, const char + **restrict SRC, size_t LEN, mbstate_t *restrict PS) + The `mbsrtowcs' function ("multibyte string restartable to wide + character string") converts an NUL-terminated multibyte character + string at `*SRC' into an equivalent wide character string, + including the NUL wide character at the end. The conversion is + started using the state information from the object pointed to by + PS or from an internal object of `mbsrtowcs' if PS is a null + pointer. Before returning, the state object is updated to match + the state after the last converted character. The state is the + initial state if the terminating NUL byte is reached and converted. - * The C library contains a set of generic conversion functions which - can read the needed conversion tables and other information from - data files. These files get loaded when necessary. + If DST is not a null pointer, the result is stored in the array + pointed to by DST; otherwise, the conversion result is not + available since it is stored in an internal buffer. - This solution is problematic as it requires a great deal of effort - to apply to all character sets (potentially an infinite set). The - differences in the structure of the different character sets is so - large that many different variants of the table processing - functions must be developed. On top of this the generic nature of - these functions make them slower than specifically implemented - functions. + If LEN wide characters are stored in the array DST before reaching + the end of the input string, the conversion stops and LEN is + returned. If DST is a null pointer, LEN is never checked. - * The C library only contains a framework which can dynamically load - object files and execute the therein contained conversion - functions. + Another reason for a premature return from the function call is if + the input string contains an invalid multibyte sequence. In this + case the global variable `errno' is set to `EILSEQ' and the + function returns `(size_t) -1'. - This solution provides much more flexibility. The C library itself - contains only very little code and therefore reduces the general - memory footprint. Also, with a documented interface between the C - library and the loadable modules it is possible for third parties - to extend the set of available conversion modules. A drawback of - this solution is that dynamic loading must be available. + In all other cases the function returns the number of wide + characters converted during this call. If DST is not null, + `mbsrtowcs' stores in the pointer pointed to by SRC either a null + pointer (if the NUL byte in the input string was reached) or the + address of the byte following the last converted multibyte + character. - Some implementations in commercial Unices implement a mixture of -these these possibilities, the majority only the second solution. Using -loadable modules moves the code out of the library itself and keeps the -door open for extensions and improvements. But this design is also -limiting on some platforms since not many platforms support dynamic -loading in statically linked programs. On platforms without his -capability it is therefore not possible to use this interface in -statically linked programs. The GNU C library has on ELF platforms no -problems with dynamic loading in in these situations and therefore this -point is moot. The danger is that one gets acquainted with this and -forgets about the restrictions on other systems. + `mbsrtowcs' was introduced in Amendment 1 to ISO C90 and is + declared in `wchar.h'. - A second thing to know about other `iconv' implementations is that -the number of available conversions is often very limited. Some -implementations provide in the standard release (not special -international or developer releases) at most 100 to 200 conversion -possibilities. This does not mean 200 different character sets are -supported. E.g., conversions from one character set to a set of, say, -10 others counts as 10 conversion. Together with the other direction -this makes already 20. One can imagine the thin coverage these platform -provide. Some Unix vendors even provide only a handful of conversions -which renders them useless for almost all uses. + The definition of the `mbsrtowcs' function has one important +limitation. The requirement that DST has to be a NUL-terminated string +provides problems if one wants to convert buffers with text. A buffer +is normally no collection of NUL-terminated strings but instead a +continuous collection of lines, separated by newline characters. Now +assume that a function to convert one line from a buffer is needed. +Since the line is not NUL-terminated, the source pointer cannot +directly point into the unmodified text buffer. This means, either one +inserts the NUL byte at the appropriate place for the time of the +`mbsrtowcs' function call (which is not doable for a read-only buffer +or in a multi-threaded application) or one copies the line in an extra +buffer where it can be terminated by a NUL byte. Note that it is not +in general possible to limit the number of characters to convert by +setting the parameter LEN to any specific value. Since it is not known +how many bytes each multibyte character sequence is in length, one can +only guess. - This directly leads to a third and probably the most problematic -point. The way the `iconv' conversion functions are implemented on all -known Unix system and the availability of the conversion functions from -character set A to B and the conversion from B to C does _not_ imply -that the conversion from A to C is available. + There is still a problem with the method of NUL-terminating a line +right after the newline character, which could lead to very strange +results. As said in the description of the `mbsrtowcs' function above +the conversion state is guaranteed to be in the initial shift state +after processing the NUL byte at the end of the input string. But this +NUL byte is not really part of the text (i.e., the conversion state +after the newline in the original text could be something different +than the initial shift state and therefore the first character of the +next line is encoded using this state). But the state in question is +never accessible to the user since the conversion stops after the NUL +byte (which resets the state). Most stateful character sets in use +today require that the shift state after a newline be the initial +state-but this is not a strict guarantee. Therefore, simply +NUL-terminating a piece of a running text is not always an adequate +solution and, therefore, should never be used in generally used code. - This might not seem unreasonable and problematic at first but it is a -quite big problem as one will notice shortly after hitting it. To show -the problem we assume to write a program which has to convert from A to -C. A call like + The generic conversion interface (*note Generic Charset Conversion::) +does not have this limitation (it simply works on buffers, not +strings), and the GNU C library contains a set of functions that take +additional parameters specifying the maximal number of bytes that are +consumed from the input string. This way the problem of `mbsrtowcs''s +example above could be solved by determining the line length and +passing this length to the function. - cd = iconv_open ("C", "A"); + - Function: size_t wcsrtombs (char *restrict DST, const wchar_t + **restrict SRC, size_t LEN, mbstate_t *restrict PS) + The `wcsrtombs' function ("wide character string restartable to + multibyte string") converts the NUL-terminated wide character + string at `*SRC' into an equivalent multibyte character string and + stores the result in the array pointed to by DST. The NUL wide + character is also converted. The conversion starts in the state + described in the object pointed to by PS or by a state object + locally to `wcsrtombs' in case PS is a null pointer. If DST is a + null pointer, the conversion is performed as usual but the result + is not available. If all characters of the input string were + successfully converted and if DST is not a null pointer, the + pointer pointed to by SRC gets assigned a null pointer. -does fail according to the assumption above. But what does the program -do now? The conversion is really necessary and therefore simply giving -up is no possibility. + If one of the wide characters in the input string has no valid + multibyte character equivalent, the conversion stops early, sets + the global variable `errno' to `EILSEQ', and returns `(size_t) -1'. - This is a nuisance. The `iconv' function should take care of this. -But how should the program proceed from here on? If it would try to -convert to character set B first the two `iconv_open' calls + Another reason for a premature stop is if DST is not a null + pointer and the next converted character would require more than + LEN bytes in total to the array DST. In this case (and if DEST is + not a null pointer) the pointer pointed to by SRC is assigned a + value pointing to the wide character right after the last one + successfully converted. - cd1 = iconv_open ("B", "A"); + Except in the case of an encoding error the return value of the + `wcsrtombs' function is the number of bytes in all the multibyte + character sequences stored in DST. Before returning the state in + the object pointed to by PS (or the internal object in case PS is + a null pointer) is updated to reflect the state after the last + conversion. The state is the initial shift state in case the + terminating NUL wide character was converted. -and + The `wcsrtombs' function was introduced in Amendment 1 to ISO C90 + and is declared in `wchar.h'. - cd2 = iconv_open ("C", "B"); + The restriction mentioned above for the `mbsrtowcs' function applies +here also. There is no possibility of directly controlling the number +of input characters. One has to place the NUL wide character at the +correct place or control the consumed input indirectly via the +available output array size (the LEN parameter). -will succeed but how to find B? + - Function: size_t mbsnrtowcs (wchar_t *restrict DST, const char + **restrict SRC, size_t NMC, size_t LEN, mbstate_t *restrict + PS) + The `mbsnrtowcs' function is very similar to the `mbsrtowcs' + function. All the parameters are the same except for NMC, which is + new. The return value is the same as for `mbsrtowcs'. - Unfortunately, the answer is: there is no general solution. On some -systems guessing might help. On those systems most character sets can -convert to and from UTF-8 encoded ISO 10646 or Unicode text. Beside -this only some very system-specific methods can help. Since the -conversion functions come from loadable modules and these modules must -be stored somewhere in the filesystem, one _could_ try to find them and -determine from the available file which conversions are available and -whether there is an indirect route from A to C. + This new parameter specifies how many bytes at most can be used + from the multibyte character string. In other words, the + multibyte character string `*SRC' need not be NUL-terminated. But + if a NUL byte is found within the NMC first bytes of the string, + the conversion stops here. - This shows one of the design errors of `iconv' mentioned above. It -should at least be possible to determine the list of available -conversion programmatically so that if `iconv_open' says there is no -such conversion, one could make sure this also is true for indirect -routes. + This function is a GNU extension. It is meant to work around the + problems mentioned above. Now it is possible to convert a buffer + with multibyte character text piece for piece without having to + care about inserting NUL bytes and the effect of NUL bytes on the + conversion state. + + A function to convert a multibyte string into a wide character string +and display it could be written like this (this is not a really useful +example): + + void + showmbs (const char *src, FILE *fp) + { + mbstate_t state; + int cnt = 0; + memset (&state, '\0', sizeof (state)); + while (1) + { + wchar_t linebuf[100]; + const char *endp = strchr (src, '\n'); + size_t n; + + /* Exit if there is no more line. */ + if (endp == NULL) + break; + + n = mbsnrtowcs (linebuf, &src, endp - src, 99, &state); + linebuf[n] = L'\0'; + fprintf (fp, "line %d: \"%S\"\n", linebuf); + } + } + + There is no problem with the state after a call to `mbsnrtowcs'. +Since we don't insert characters in the strings that were not in there +right from the beginning and we use STATE only for the conversion of +the given buffer, there is no problem with altering the state. + + - Function: size_t wcsnrtombs (char *restrict DST, const wchar_t + **restrict SRC, size_t NWC, size_t LEN, mbstate_t *restrict + PS) + The `wcsnrtombs' function implements the conversion from wide + character strings to multibyte character strings. It is similar to + `wcsrtombs' but, just like `mbsnrtowcs', it takes an extra + parameter, which specifies the length of the input string. + + No more than NWC wide characters from the input string `*SRC' are + converted. If the input string contains a NUL wide character in + the first NWC characters, the conversion stops at this place. + + The `wcsnrtombs' function is a GNU extension and just like + `mbsnrtowcs' helps in situations where no NUL-terminated input + strings are available. diff -durpN glibc-2.2.4/manual/libc.pg glibc-2.2.5/manual/libc.pg --- glibc-2.2.4/manual/libc.pg Mon Aug 13 15:04:27 2001 +++
