NAME

SYNOPSIS

9              #include <allegro5/allegro.h>
10
11              void al_update_display_region(int x, int y, int width, int height)
12

DESCRIPTION

14       Does the same as al_flip_display(3), but tries to update only the spec‐
15       ified region.  With many drivers this is not possible, but for some  it
16       can improve performance.  If this is not supported, this function falls
17       back to the behavior of al_flip_display(3).  You can query the  support
18       for   this  function  using  al_get_display_option(display, ALLEGRO_UP‐
19       DATE_DISPLAY_REGION).
