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.

RETURN VALUE
       Returns a pointer to a list structure of the type GFX_MODE_LIST or NULL
       if the request could not be satisfied.
