SDL_VideoModeOK — Check to see if a particular video mode is supported.
#include "SDL.h"
int
SDL_VideoModeOK( |
int | width, |
| int | height, | |
| int | bpp, | |
| Uint32 | flags); |
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
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);
