SDL_VideoModeOK(3) SDL API Reference SDL_VideoModeOK(3)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);
DESCRIPTIONSDL_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 set-
ting 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);
