NAME
get_gfx_mode_list - Obtains a list of available video modes. Allegro game programming library.SYNOPSIS
#include <allegro.h>
GFX_MODE_LIST *get_gfx_mode_list(int card);
DESCRIPTION
Attempts to create a list of all the supported video modes for a certain graphics driver, made up from the GFX_MODE_LIST structure, which has the following definition:
typedef struct GFX_MODE_LIST { int num_modes; GFX_MODE *mode; } GFX_MODE_LIST;The mode entry points to the actual list of video modes.
typedef struct GFX_MODE { int width, height, bpp; } GFX_MODE;This list of video modes is terminated with an { 0, 0, 0 } entry.
Note that the card parameter must refer to a _real_ driver. This function fails if you pass GFX_SAFE, GFX_AUTODETECT, or any other "magic" driver.
