al_wait_for_vsync(3)al_wait_for_vsync(3)NAMEal_wait_for_vsync - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro.h>
bool al_wait_for_vsync(void)DESCRIPTION
Wait for the beginning of a vertical retrace. Some driver/card/monitor
combinations may not be capable of this.
Note how al_flip_display(3) usually already waits for the vertical
retrace, so unless you are doing something special, there is no reason
to call this function.
Returns false if not possible, true if successful.
