DOS/32 Advanced DOS Extender - Programmer's Reference 3.25 - DOS function 4Bh - Execute Program (sub-function 00h)
In: | AH = 4Bh AL = 00h DS:EDX = pointer to ASCIIZ path name ES:EBX = pointer to parameter block
Out: | if successful: CF clear if failed: CF set EAX = DOS error code
Notes: a) DOS/32 Advanced will copy the environment provided by the protected mode program into conventional (DOS) memory where it can be reached by the real mode DOS. b) This function will return an error (EAX=0FFFFFFFFh and CF set) when there was not enough conventional (DOS) memory for the protected mode program's environment, or when the DPMI host could not allocate a selector for the allocated memory block. c) The only supported sub-function is AL=00h. Refer to "DOS/32 Advanced Technical Reference" documentation for more information on how to use this function and how to spawn programs under DOS/32 Advanced DOS Extender.
