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);
       .
       .
