Function sdl2_sys::SDL_GameControllerGetJoystick

pub unsafe extern "C" fn SDL_GameControllerGetJoystick(
    gamecontroller: *mut SDL_GameController,
) -> *mut SDL_Joystick
Expand description

Get the Joystick ID from a Game Controller.

This function will give you a SDL_Joystick object, which allows you to use the SDL_Joystick functions with a SDL_GameController object. This would be useful for getting a joystick’s position at any given time, even if it hasn’t moved (moving it would produce an event, which would have the axis’ value).

The pointer returned is owned by the SDL_GameController. You should not call SDL_JoystickClose() on it, for example, since doing so will likely cause SDL to crash.

\param gamecontroller the game controller object that you want to get a joystick from \returns a SDL_Joystick object; call SDL_GetError() for more information.

\since This function is available since SDL 2.0.0.
