I am using 2.04.
I was hoping a hint might spark some documentation on the FreeDOS filesystem
API
so others (like me) can do development. :-)
you might see an increase in freedos programs if your API was documented. who
knows, maybe even commercial systems might be made or something.
I am hoping to implement some sort of fallback mechanism into the program so
that if int 21h, 7303h fails, I have int 21h, 36h to fall back on.
but I need to know exactly how to detect failure. not every programmer writing
production code does that... so I need documentation.
like for instance, is the carry bit set or cleared or something?

I think DJGPP does (try to) use int 21h, 7303h sometimes, but modern
NT-based Windows (XP etc.) don't support it, IIRC, which complicates
the matters. DJGPP does have its own DU.EXE (fil41[sb].zip), so you
could check the sources for that. Also, are you using 2.03p2? Call it
a hunch, but I'd suspect 2.04 would be more complete (better 4 GB file
support, says Charles). You could also email djgpp-workers or CWS
directly or even go back to comp.os.msdos.djgpp.
