al_toggle_display_flag
bool al_toggle_display_flag(ALLEGRO_DISPLAY *display, int flag, bool onoff)
Enable or disable one of the display flags. The flags are the same as for al_set_new_display_flags. The only flags that can be changed after creation are:
- ALLEGRO_FULLSCREEN_WINDOW
- ALLEGRO_NOFRAME
Returns true if the driver supports toggling the specified flag else false. You can use al_get_display_flags to query whether the given display property actually changed.
