SDL_VideoModeOK(3)			SDL API Reference		       SDL_VideoModeOK(3)

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);
       .
       .
