I posted about this once before, but I didn't see my own post so
perhaps it got lost.
I need to arrange to have an arbitrary C function of mine called 60
times a second. setitimer() doesn't seem to be supported. I've
noticed that the PC has the appropriate VBL interrupt, but I do not
yet know enough about PC's to write this interrupt handler and
install it. I have, however, written interrupt handlers on various
other machines.
If someone could point me to the documentation I need (do I need to
buy Turbo C?), I can get to work on it. My problem is that there are
so many PC books out there it is difficult to sort the trash from the
good stuff, and I don't really know how everything fits together with
the djgpp environment.
If I get this written, I am willing to contribute this package to
djgpp as freeware. On the other hand, there are certainly PC hackers
out there who could write this ten times faster than I could. If
anyone wants to take a little time to throw this together, or even
just let me know what problems I am likely to encounter, I would
greatly appreciate it.
