get_gfx_mode_list(3) Allegro manual get_gfx_mode_list(3)NAMEget_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 cer‐
tain 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 func‐
tion 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.
