al_wait_for_vsync(3)	    Library Functions Manual	    al_wait_for_vsync(3)

NAME
     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.
