Subject:	real-time graphics

I want to write a real-time graphics application with millisecond resolution
for vision experiments, using the 1 MHz PC speaker timer as recommended in
Frank Van Gilluwe's book, _The_Undocumented_PC_.

Is DJGPP a good compiler to use for this purpose?  From recent discussions
it seems that it will be possible to hook interrupts, etc., and that is what
I need.

But what about the graphics control?  Is there a screen-blanking call
available, or am I limited to detecting vertical refreshes?  Can I trigger
graphics page-swapping on them?

In general, how will my real-time wishes be spoiled by the fact that I'm
programming in a DOS window in Win95 and WinNT?  I have not tried to do
real-time programming in a multi-tasking environment before, so if I'm in
for a lot of frustration I'd like to hear about it before I waste a few weeks.

Thanks,
Roger Noss
