I am not sure if I do get your question, but
the DPMI API is rather well documented, IIRC, DJ has a copy
of the specs on his www-server. Basically, a "bare-bone" application
must do the following steps (at least)
 
 - Check if a DPMI host is available
 - Start CWSDPMI if not.

Then, the API is pretty much the same under different DPMI hosts, 
and you could call the API anyway you like. You could do this 
e.g.,from Turbo Pascal and a TASM lib to stuff the right values
into the right registers. Still, the use is not very clear to 
me because another RTLib doesn't know to benefit from the offers.
It is then probably much like the pain when swapping memory
to EMS/XMS/Disk under TP, where you had to do all this by
yourself.
