Code Examples

/* 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.\n");
} else {
    printf("Video is not initialized.\n");
}

/* Just check for one specific subsystem */

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

/* Check for two subsystems */
Uint32 subsystem_mask = SDL_INIT_VIDEO | SDL_INIT_AUDIO;

if (SDL_WasInit(subsystem_mask) == subsystem_mask) {
