#include <allegro5/allegro.h>
int al_get_num_display_modes(void)

will use the values set with al_set_new_display_refresh_rate(3alleg5), and al_set_new_display_flags(3al‐
leg5) to find the number of modes that match. Settings the new display parameters to zero will give a
list of all modes for the default driver.
