al_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.
