Code: Select all

void vsync(void)
{
// wait for verticle retrace to avoid flicker
while (inportb(0x3da) & 0x08);
/* vga is in retrace */
while (!(inportb(0x3da) & 0x08));
/* wait for start of retrace */
}

Then all you need to do is modify your do-while loop in main() to look like this:

do
{
set_hot(); // generate random hotspots
mk_lines(); // do all the math and screen updating
vsync();
flip(); // move your new frame to the video screen
} while(!kbhit());
