I don't think "a lot" is the right term here - "a few" is more like it:

DPMI 1.0: function 0x0506 -> __dpmi_get_page_attributes()
DPMI 1.0: function 0x0507 -> __dpmi_set_page_attributes(), mprotect()
DPMI 1.0: function 0x0508 -> __dpmi_map_device_in_memory_block()
DPMI 1.0: function 0x0509 ->
                          __dpmi_map_conventional_memory_in_memory_block()
DPMI 1.0: function 0x0E01 -> __dpmi_get_coprocessor_status()

I particularly remember that CWSDPMI doesn't implement any of the shared
memory calls.

BTW I compiled a list of DPMI 1.0 -> DJGPP function name mappings, if
anyone's interested.

Bye,
