Function sdl2_sys::SDL_JoystickEventState

source · 
pub unsafe extern "C" fn SDL_JoystickEventState(state: c_int) -> c_int
Expand description

Enable/disable joystick event polling.

If joystick events are disabled, you must call SDL_JoystickUpdate() yourself and manually check the state of the joystick when you want joystick information.

It is recommended that you leave joystick event handling enabled.

WARNING: Calling this function may delete all events currently in SDL’s event queue.

\param state can be one of SDL_QUERY, SDL_IGNORE, or SDL_ENABLE \returns 1 if enabled, 0 if disabled, or a negative error code on failure; call SDL_GetError() for more information.

     If `state` is `SDL_QUERY` then the current state is returned,
     otherwise the new processing state is returned.

\since This function is available since SDL 2.0.0.
