DISP.H seems a bit sluggish in comparison with Curses. I've tried running curses for DJGPP with DM C++, but it didn't work; I'll have to settle for disp.h, but it is displaying undesirable effects on the screen on each screen update in a loop; by that I mean that when the screen updates, I see a black scanline blocky effect, which moves up the screen in a pattern.

I include a link to a program I compiled, for demonstration.
