logger_get_logged_devices_c

	status.i4.v = logger_get_logged_devices_c(node.i4.v, list.i4.v,
						  num_devices.u4.r,
						  devices.sp.r)

	This routine returns which devices are being datalogged.

	node		requested Lumberjack node
			(Passing a value of LOGGER_ANY_NODE results in
			 returning devices from all nodes.)
	list		requested list number (Passing a value of
			LOGGER_ALL_LISTS results in returning data for
			all lists.)
	num_devices	returned number of devices found
	devices		returned device information
			(array of ARRAY_DEVICE_DATA_EXT structures)
			(Note: This is a pointer to a buffer allocated by
			 this routine. The caller should neither allocate
			 nor free this buffer.)

	This function returns ACNET status values as follows:

	OK			success
	LJ_MEMFAIL		dynamic memory allocation failure
	SQL_xxx			error in communicating with Database

	This function requires the following include files:

	cnsparam_h, cns_data_structs_h, clib_h, acnet_errors_h
