SDL_VideoModeOK

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);
 .
 .
