SDL_ListModes

NAME

SDL_ListModes- Returns a pointer to an array of available screen dimensions for the given format and video flags

SYNOPSIS

#include "SDL.h"

SDL_Rect **SDL_ListModes(SDL_PixelFormat *format, Uint32 flags);

DESCRIPTION

Return a pointer to an array of available screen dimensions for the given format and video flags, sorted largest to smallest. Returns NULL if there are no dimensions available for a particular format, or -1 if any dimension is okay for the given format.

If format is NULL, the mode list will be for the format returned by SDL_GetVideoInfo()->vfmt. The flag parameter is an OR'd combination of surface flags. The flags are the same as those used SDL_SetVideoMode and they play a strong role in deciding what modes are valid. For instance, if you pass SDL_HWSURFACE as a flag only modes that support hardware video surfaces will be returned.

EXAMPLE

 SDL_Rect **modes;
 int i;
 .
 .
 .
 
 /* Get available fullscreen/hardware modes */
 modes=SDL_ListModes(NULL, SDL_FULLSCREEN|SDL_HWSURFACE);
 
 /* Check is there are any modes available */
 if(modes == (SDL_Rect **)0){
   printf("No modes available!
 ");
   exit(-1);
 }
 
 /* Check if or resolution is restricted */
 if(modes == (SDL_Rect **)-1){
   printf("All resolutions available.
 ");
 }
 else{
   /* Print valid modes */
   printf("Available Modes
 ");
   for(i=0;modes[i];++i)
     printf("  %d x %d
 ", modes[i]->w, modes[i]->h);
 }
 .
