.SH "NAME"

SDL_VideoModeOK\- Check to see if a particular video mode is supported\&.

.SH "SYNOPSIS"

.PP

\fB#include "SDL\&.h"

.sp

\fBint \fBSDL_VideoModeOK\fP\fR(\fBint width, int height, int bpp, Uint32 flags\fR);

.SH "DESCRIPTION"

.PP

\fBSDL_VideoModeOK\fP returns \fB0\fR 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 \fIsurface\fR flags (see \fI\fBSDL_SetVideoMode\fP\fR)\&.

.PP

The bits-per-pixel value returned is only a suggested mode\&. You can usually request and bpp you want when \fIsetting\fR the video mode and SDL will emulate that color depth with a shadow video surface\&.

.PP

The arguments to \fBSDL_VideoModeOK\fP are the same ones you would pass to \fISDL_SetVideoMode\fR

.SH "EXAMPLE"

.PP

.nf

\f(CWSDL_Surface *screen;

Uint32 bpp;

printf("Checking mode 640x480@16bpp\&.

");

if(!bpp){

printf("Mode not available\&.

");

exit(-1);

}

printf("SDL Recommends 640x480@%dbpp\&.

", bpp);

screen=SDL_SetVideoMode(640, 480, bpp, SDL_HWSURFACE);
