al_flip_display(3)                                          al_flip_display(3)

NAME
       al_flip_display - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_flip_display(void)

DESCRIPTION
       Copies or updates the front and back buffers so that what has been
       drawn previously on the currently selected display becomes visible on
       screen.  Pointers to the special back buffer bitmap remain valid and
       retain their semantics as the back buffer, although the contents may
       have changed.

       Several display options change how this function behaves:

       o With ALLEGRO_SINGLE_BUFFER, no flipping is done.  You still have to
         call this function to display graphics, depending on how the used
         graphics system works.

       o The ALLEGRO_SWAP_METHOD option may have additional information about
         what kind of operation is used internally to flip the front and back
         buffers.

       o If ALLEGRO_VSYNC is 1, this function will force waiting for vsync.
         If ALLEGRO_VSYNC is 2, this function will not wait for vsync.  With
         many drivers the vsync behavior is controlled by the user and not the
         application, and ALLEGRO_VSYNC will not be set; in this case
         al_flip_display(3) will wait for vsync depending on the settings set
         in the system's graphics preferences.
