Too bad they don't conform to posix.  Where are named pipes and fifos
when you need them.

Well - two things come to mind here.  Windows has support for sharing
memory between two windows processes.  Its possible if you can figure
out where the shared memory is that you could access from DJGPP
though far pointers.  Don't know how you would do this though.

The other option would be to allocate dos memory.  This way, you would
know the absolute address and should (don't know under windows) be
able to get at it now problem from both.
