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);
       .
       .
