Word description
Reads the current state of controller. See the documentation for the controller-state class for details of the returned value's format. If the device is no longer available, f is returned.

Warning
For efficiency, the implementation may reuse the returned controller-state object next time read-controller is called on the same controller. You should clone any values from the returned tuple you need to preserve.
