al_get_display_mode

ALLEGRO_DISPLAY_MODE *al_get_display_mode(int index, ALLEGRO_DISPLAY_MODE *mode)

Retrieves a fullscreen mode. Display parameters should not be changed between a call of al_get_num_display_modes and al_get_display_mode. index must be between 0 and the number returned from al_get_num_display_modes-1. mode must be an allocated ALLEGRO_DISPLAY_MODE structure. This function will return NULL on failure, and the mode parameter that was passed in on success.

al_get_num_display_modes

int al_get_num_display_modes(void)

Get the number of available fullscreen display modes for the current set of display parameters. This will use the values set with al_set_new_display_refresh_rate, and al_set_new_display_flags 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.
