In AudioHardware.h, the documentation @params do not match the function arguments for either of these functions:

/*!
    @function       AudioObjectRemovePropertyListener
    @abstract       Unregisters the given AudioObjectPropertyListenerProc from receiving
                    notifications when the given properties change.
    @param          inObjectID
                        The AudioObject to unregister the listener from.
    @param          inNumberAddresses
                        The number of elements in the inAddresses array.
    @param          inAddresses
                        The AudioObjectPropertyAddress indicating which property the listener should
                        be removed from.
    @param          inListener
                        The AudioObjectPropertyListenerProc being removed.
    @param          inClientData
                        A pointer to client data that is passed to the listener when it is called.
    @result         An OSStatus indicating success or failure.
