FAQ section 16.2 should explain most of it.

In general, the `__dpmi' group of functions are direct connections to the
standard DPMI services. The `_go32' functions are similar, but sometimes
have extra functionality. They mostly exist for backward compatibility to
DJGPP v1. See also FAQ section 18.10. The `__djgpp' functions, where they
exist, normally provide more convenient interfacing.
