Subject: Creating a new segment under DJGPP

Hi.  I've got a problem involving dynamically loading some driver code
from a file into memory, and then executing code in the file.  I need to
create a segment, read the file into it, and then call functions in that
code.  The file needs to be loaded at offset 0 in the segment, as it
accesses its own data.

I hope I've explained what I mean enough!

As a rough guess, I think the kind of thing that needs to be done is:
	malloc a block of memory (I only need something around 500
		bytes or so)
	read the file into the block
	setup a segment with R/W access, with its base address at the
		start of the malloc'ed block
	execute some kind of call to a location in that segment

I think I can do all of that except setup the segment bit.  Is it
possible to setup a segment in this way (in DJGPP), or do I have to
look for another way of doing things?

Thanks for any ideas.
