enable_triple_buffer - Enables triple buffering. Allegro game programming
library.
#include <allegro.h>
int enable_triple_buffer();
If the GFX_CAN_TRIPLE_BUFFER bit of the gfx_capabilities field is not set, you
can attempt to enable it by calling this function. In particular 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.
Returns zero if triple buffering is enabled, -1 otherwise.
