SDL_ListModes(3) SDL API Reference SDL_ListModes(3)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);
}
