logger_devices_from_node_c

	status.i4.v = logger_devices_from_node_c(node.i4.v, logger_node.i4.v,

						 num_found.u4.r,
						 found_devices.sp.r

	This routine returns information about logged devices which
	are sourced from a given their device name.

	node		device source node
			(constants are in 'nodedefs')
	logger_node	data logger node
			(Passing a value 0 results in returning data from all
			 nodes which are logging devices from the source node.)
			(constants are in 'nodedefs')
	event_string	requested event (a value of NULL may be passed if
			a data event search is not needed)
			(up to DATA_EVENT_MAX_LEN characters)
			(example: "p,10000,true")
	num_found	returned number of entries found
	found_devices	returned datalogging information
			(array of LOGGER_SEARCH_DATA structures)
			(Note: This is a pointer to a buffer allocated by
			 this routine. The caller is responsible for freeing
			 this buffer.)
	[options]	search options
			(LOGGER_OPT_NONE -> no options selected (default),
			 LOGGER_OPT_ORDER_BY_NODE -> order results by logger
						     node (default is by
						     device name))

	This function returns ACNET status values as follows:
