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(3alleg5) 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.
