al_set_display_option3alleg5

Usage

Overview

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(3alleg5). Calling al_set_new_display_option(3alleg5) subsequently only changes options for newly created displays, and doesn’t touch the options of already created displays. al_set_display_option(3alleg5) 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.

•

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(3alleg5) for more information on this option.
