- bpp, Uint32 flags</b>);
- <h2><a name='sect2' href='#toc2'>Description</a></h2>
- <p>
- <b>SDL_VideoModeOK</b> returns <b>0</b> 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
- <i>surface</i> flags (see <i><b>SDL_SetVideoMode</b></i>). <p>
- The bits-per-pixel value returned is
- only a suggested mode. You can usually request and bpp you want when <i>setting</i>
- the video mode and SDL will emulate that color depth with a shadow video
- surface. <p>
- The arguments to <b>SDL_VideoModeOK</b> are the same ones you would pass
- to <i>SDL_SetVideoMode</i>
