DOS/32 Advanced DOS Extender - Programmer's Reference 2.42 - DPMI function 0703h - Discard Page Contents Discards the entire contents of a given linear memory range. This function is used when a memory object (such as a data structure) that occupies a given area of memory is no longer needed, so that the area will not be paged to disk unnecessarily. The contents of the discarded region will be undefined.
In: | AX = 0703h BX:CX = starting linear address of pages to discard SI:DI = size of region to discard (bytes)
Out: | if successful: CF clear if failed: CF set AX = error code 8025h - invalid linear address (range unallocated)
Notes: a) DOS/32 Advanced DPMI will perform no action on this function and will always return with carry flag clear. Copyright © DOS/32 Advanced Team 1996-2002 All Rights Reserved
