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.
