RETURN VALUE

SDL_WasInit returns a bitwised OR’d combination of the initialized subsystems.

EXAMPLES


/* Here are several ways you can use SDL_WasInit() */

/* Get init data on all the subsystems */ Uint32 subsystem_init;

subsystem_init=SDL_WasInit(SDL_INIT_EVERYTHING);

if(subsystem_init&SDL_INIT_VIDEO) printf("Video is initialized. "); else printf("Video is not initialized. ");

/* Just check for one specfic subsystem */

if(SDL_WasInit(SDL_INIT_VIDEO)!=0) printf("Video is initialized. "); else printf("Video is not initialized. ");

/* Check for two subsystems */

Uint32 subsystem_mask=SDL_INIT_VIDEO|SDL_INIT_AUDIO;

if(SDL_WasInit(subsystem_mask)==subsystem_mask) printf("Video and Audio initialized. "); else printf("Video and Audio not initialized. ");
