SoNodeSensor(3IV)

DESCRIPTION
     Node sensors detect changes to nodes, calling a callback function
     whenever any field of the node or, if the node is a group node, any
     children of the node change.

FUNCTIONS
     SoNodeSensor *	 SoNodeSensCreate()
     SoNodeSensor *	 SoNodeSensCreateCB(SoSensorCB *func, void *data)
	  Creation methods. The second method takes the callback function and
	  data to be called when the sensor is triggered.

     void		 SoNodeSensDelete(SoNodeSens *this)
	  Destroys the sensor, freeing up any memory associated with it after
	  unscheduling it.

     void		 SoNodeSensAttach(SoNodeSens *this, SoNode *node)
     void		 SoNodeSensDetach(SoNodeSens *this)
     SoNode *		 SoNodeSensGetAttachedNode(const SoNodeSens *this)
	  The attach() method makes this sensor detect changes to the given
	  node. The detach() method unschedules this sensor (if it is
	  scheduled) and makes it ignore changes to the scene graph. The
	  getAttachedNode() method returns the node that this sensor is
	  sensing, or NULL if it is not attached to any node.
