kStatus kHxNode_AddHealthUpdateHandler	(	kHxNode	node,
		kCallbackFx	function,
		kPointer	receiver
	)

Registers a callback function for periodic health updates.

This function allows an application to take advantage of the health polling infrastructure that already exists within the kHardware library, rather than duplicating that infrastructure. Registered callbacks should be fast; non-negligible blocking will interfere with health processsing.
