# al\_wait\_for\_vsync(3alleg5)

Allegro 5 API

## 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.
