`callback`	The callback function that notifies whether the Wii Remote for the specified channel was connected or disconnected.

Registers the callback function that notifies whether the Wii Remote for the specified channel was connected or disconnected. If NULL is specified, no notifications are made until reset.

When the Wii Remote is connected, WPAD_ERR_NONE is passed as the result argument that is passed to the callback function; at disconnection, WPAD_ERR_NO_CONTROLLER is passed.
