NAME
       al_set_display_option - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_set_display_option(ALLEGRO_DISPLAY *display, int option, int value)


DESCRIPTION
       Change an option that was previously set for a display.  After displays
       are created, they take on the options set with
       al_set_new_display_option(3).  Calling al_set_new_display_option(3)
       subsequently only changes options for newly created displays, and
       doesn't touch the options of already created displays.
       al_set_display_option(3) allows changing some of these values.  Not all
       display options can be changed or changing them will have no effect.
       Changing options other than those listed below is undefined.

       o ALLEGRO_SUPPORTED_ORIENTATIONS - This can be changed to allow new or
         restrict previously enabled orientations of the screen/device.  See
         al_set_new_display_option(3) for more information on this option.

SINCE
