enable_triple_buffer (3alleg4)

#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.
