SDL_JoystickGUID SDL_JoystickGetGUID(SDL_Joystick *joystick);

```

| ---------------- | ------------------------------------------------------------------------------------- |
| **joystick**     | the [SDL_Joystick](SDL_Joystick) obtained from [SDL_JoystickOpen](SDL_JoystickOpen)() |

## Return Value

function returns a zero GUID; call [SDL_GetError](SDL_GetError)() for more
information.
