(This is the documentation for SDL3, which is under heavy development and the API is changing! SDL2 is the current stable version!)

SDL_WasInit

Get a mask of the specified subsystems which are currently initialized.

Header File

Defined in SDL_init.h, but apps should use #include <SDL3/SDL.h>

Uint32 SDL_WasInit(Uint32 flags);

Function Parameters

flags

any of the flags used by SDL_Init(); see SDL_Init for details.

Return Value

Returns a mask of all initialized subsystems if flags is 0, otherwise it returns the initialization status of the specified subsystems.

Version

This function is available since SDL 3.0.0.

Code Examples

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

subsystem_init = SDL_WasInit(SDL_INIT_AUDIO | SDL_INIT_VIDEO);

if (subsystem_init & SDL_INIT_VIDEO) {
    SDL_Log("Video is initialized.");
} else {
    SDL_Log("Video is not initialized.");
}

/* Just check for one specific subsystem */

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

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

if (SDL_WasInit(subsystem_mask) == subsystem_mask) {
    SDL_Log("Video and Audio initialized.");
} else {
    SDL_Log("Video and Audio not initialized.");
}
