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\&..PPIf \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\&..SH "EXAMPLE".PP.nf\f(CWSDL_Rect **modes;int i;\&.\&.\&./* Get available fullscreen/hardware modes */modes=SDL_ListModes(NULL, SDL_FULLSCREEN|SDL_HWSURFACE);/* Check is there are any modes available */if(modes == (SDL_Rect **)0){  printf("No modes available!");  exit(-1);}/* Check if or resolution is restricted */if(modes == (SDL_Rect **)-1){  printf("All resolutions available\&.");}else{  /* Print valid modes */  printf("Available Modes");  for(i=0;modes[i];++i)    printf("  %d x %d", modes[i]->w, modes[i]->h);}\&.\&.\fR.fi.PP.SH "SEE ALSO".PP\fI\fBSDL_SetVideoMode\fP\fR, \fI\fBSDL_GetVideoInfo\fP\fR, \fI\fBSDL_Rect\fR\fR, \fI\fBSDL_PixelFormat\fR\fR...\" created by instant / docbook-to-man, Tue 11 Sep 2001, 23:01
