SDL_VideoModeOK(3)	       SDL API Reference	    SDL_VideoModeOK(3)


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); . .
