NAME

SDL_VideoModeOK- Check to see if a particular video mode is supported.

SYNOPSIS

#include "SDL.h"

int SDL_VideoModeOK(int width, int height, int bpp, Uint32 flags);

DESCRIPTION

SDL_VideoModeOK returns 0 if the requested mode is not supported under any bit depth, or returns the bits-per-pixel of the closest available mode with the given width, height and requested surface flags (see SDL_SetVideoMode).

The bits-per-pixel value returned is only a suggested mode. You can usually request and bpp you want when setting the video mode and SDL will emulate that color depth with a shadow video surface.

The arguments to SDL_VideoModeOK are the same ones you would pass to SDL_SetVideoMode

EXAMPLE


SDL_Surface *screen;

Uint32 bpp;

.

.

.

printf("Checking mode 640x480@16bpp.

");

bpp=SDL_VideoModeOK(640, 480, 16, SDL_HWSURFACE);



if(!bpp){

  printf("Mode not available.

");

  exit(-1);

}



printf("SDL Recommends 640x480@%dbpp.

", bpp);

screen=SDL_SetVideoMode(640, 480, bpp, SDL_HWSURFACE);
