SYNOPSIS

10       #include <allegro.h>

13       GFX_MODE_LIST *get_gfx_mode_list(int card);
14

DESCRIPTION

16       Attempts to create a list of all the supported video modes for  a  cer‐
17       tain  graphics  driver, made up from the GFX_MODE_LIST structure, which
18       has the following definition:
19
20          typedef struct GFX_MODE_LIST
21          {
22             int num_modes;
23             GFX_MODE *mode;
24          } GFX_MODE_LIST;
25
26       The mode entry  points to the actual list of video modes.
27
28          typedef struct GFX_MODE
29          {
30             int width, height, bpp;
31          } GFX_MODE;
32
33       This list of video modes is terminated with an { 0, 0, 0 } entry.
34
35       Note that the card parameter must refer to a _real_ driver. This  func‐
36       tion  fails  if you pass GFX_SAFE, GFX_AUTODETECT, or any other "magic"
37       driver.

RETURN VALUE

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