3 SDL_ListModes \- Returns a pointer to an array of available screen dimensions for the given format and video flags
8 \fBSDL_Rect **\fBSDL_ListModes\fP\fR(\fBSDL_PixelFormat *format, Uint32 flags\fR);
11 Return a pointer to an array of available screen dimensions for the given format and video flags, sorted largest to smallest\&. Returns \fBNULL\fP if there are no dimensions available for a particular format, or \fB-1\fR if any dimension is okay for the given format\&.
13 If \fBformat\fR is \fBNULL\fP, the mode list will be for the format returned by \fISDL_GetVideoInfo()\fR->\fBvfmt\fR\&. The \fBflag\fR parameter is an OR\&'d combination of \fIsurface\fR flags\&. The flags are the same as those used \fI\fBSDL_SetVideoMode\fP\fR and they play a strong role in deciding what modes are valid\&. For instance, if you pass \fBSDL_HWSURFACE\fP as a flag only modes that support hardware video surfaces will be returned\&.
17 \f(CWSDL_Rect **modes;
23 /* Get available fullscreen/hardware modes */
24 modes=SDL_ListModes(NULL, SDL_FULLSCREEN|SDL_HWSURFACE);
26 /* Check is there are any modes available */
27 if(modes == (SDL_Rect **)0){
28 printf("No modes available!
33 /* Check if or resolution is restricted */
34 if(modes == (SDL_Rect **)-1){
35 printf("All resolutions available\&.
39 /* Print valid modes */
40 printf("Available Modes
44 ", modes[i]->w, modes[i]->h);
