Kind of yes, Kind of no. Borland handles Seg and Offset for the programmer, DPMI uses selector and offset, which is quite different. (but much easier to deal with than overlapping segments and all that garbage).

Personally, I have to ask why you want a segment and offset in a 32bit DPMI program?

If it is to interface with the BIOS or some TSR or other interrupt service that expects such a thing, check out the DJGPP FAQ, it goes into quite a bit of detail on the matter.

You may very well want to track down a copy of the DPMI 1.0 specs, they will give you a much more in-depth explanation of the environment you'll be working in with DJGPP.

Good luck.
