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);
