NAME
enable_triple_buffer - Enables triple buffering. Allegro game programming library. SYNOPSIS

In par- ticular if you are running in mode-X in a clean DOS environment, this routine will enable the timer retrace simulator, which will activate the triple buffering functions. RETURN VALUE

NAME
ex3buf - Mode-X triple buffering and retrace interrupt simulation. Allegro game programming library. SYNOPSIS
#include <allegro.h> Example ex3buf DESCRIPTION
This program demonstrates the use of triple buffering. Several triangles are displayed rotating and bouncing on the screen until you press a key. Note that on some platforms you can't get real hardware triple buffering. The Allegro code remains the same, but most likely the graphic driver will emulate it. Unfortunately, in these cases you can't expect the animation to be completely smooth and flicker free. SEE ALSO
