SDL API Reference SDL_ListModes(3)
NAME
SDL_ListModes - Returns a pointer to an array of available
screen dimensions for the given format and video flagsSYNOPSIS
#include "SDL.h"
SDL_Rect **SDL_ListModes(SDL_PixelFormat *format, Uint32
flags);DESCRIPTION
Return a pointer to an array of available screen dimensions for the given format and video flags, sorted largest to smallest. Returns NULL if there are no dimensions availablefor a particular format, or -1 if any dimension is okay for
the given format. If format is NULL, the mode list will be for the formatreturned by SDL_GetVideoInfo()->vfmt. The flag parameter is
an OR'd combination of surface flags. The flags are the sameas those used SDL_SetVideoMode and they play a strong role
in deciding what modes are valid. For instance, if you passSDL_HWSURFACE as a flag only modes that support hardware
video surfaces will be returned.EXAMPLE
SDL_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) SDL Last change: Tue 11 Sep 2001, 23:01 1SDL API Reference SDL_ListModes(3)
