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(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.
