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:
- •
- 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.
- •
- The ALLEGRO_SWAP_METHOD option may have additional information about what
kind of operation is used internally to flip the front and back
buffers.
- •
- 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(3alleg5) will wait for vsync depending on the settings set
in the system's graphics preferences.
