I'm new to programming in DJGPP and Allegro. I used to program C/C++ in
TurboC, real mode. My problem is that I used to put a lot of funtions which
control the movement of sprites in an interrupt-handler, but Allegro says
you should lock the functions and variables before using them in an
protected-mode interrupt-handler. How do I go about that with all the
functions I use?!? The reason I used this method was to let the sprites
always move 25 or 50 times a second even on computers which do not get a
framerate of 25/50, but what other way is there to achieve this?
