status.i4.v = logger_read_device_status_list_c(device_indices.i4a.r,
						       nodes.u2a.r, time.u4.v,

	This routine returns a single logged status value for one
	or more devices.

	device_indices	device index or an array of device indices
	array_indices	index into array device or an array of indices
			(starts at 0)  (If a value of NULL is passed for
			this argument, an array index of zero will be
			used for all devices.)
	nodes		Lumberjack source node or array of nodes
			(LOGGER_ANY_NODE -> routine picks a node logging this
					    device and property,
			 LOGGER_FASTEST_NODE -> routine picks node which is
						logging this device and
						property at the fastest rate,
			 LOGGER_COLLIDER_SDA_NODE -> Collider SDA node,
			 LOGGER_PBAR_SDA_NODE -> Pbar SDA node,
			 otherwise -> Lumberjack node value
				      (constants are in nodedefs))
	time		data acquisition time
			(seconds since January 1, 1970 UTC)
	nanos		acquisition time offset in nanoseconds
	num_devices	number of devices
	timestamps	returned timestamp value or an array of timestamp
	nanoseconds	returned timestamp fractions of a second in
			nanoseconds or array of nanoseconds
	on_states	returned on/off status values
			(TRUE -> device was on,
			 FALSE -> device was off,
			 DIO_NOATT -> on/off attribute not defined)
	ready_states	returned ready/tripped status values
			(TRUE -> device was ready,
			 FALSE -> device was tripped,
			 DIO_NOATT -> ready/tripped attribute not defined)
	remote_states	returned remote/local status values
			(TRUE -> device was in remote,
			 FALSE -> device was in local,
			 DIO_NOATT -> remote/local attribute not defined)
	positive_states	returned polarity status values
			(TRUE -> device was in positive polarity,
			 FALSE -> device was in negative polarity,
			 DIO_NOATT -> polarity attribute not defined)
	ramp_states	returned ramp/DC status values
			(TRUE -> device was ramping,
			 FALSE -> device was DC,
			 DIO_NOATT -> ramp/DC attribute not defined)
	status_text	returned DIO_NUM_STATUS_TYPES + 1 characters of XCHAR
			format color coded status text
			(array of XCHAR structures)
	errors		returned ACNET status value or an array of returned
			ACNET status values
			(OK -> success,
			 DBM_NOREC -> invalid device index,
			 LJ_INVARG -> invalid property or array index,
			 LJ_NO_SUCH -> requested Lumberjack does not have the
				       requested device and property or there
				       is no data point at the requested time)
	[sample_spec]	data sample specifier whose type depends on the
			value of the "sample_type" argument
			(LOGGER_SAMPLE_TYPE_DATA_EVENT -> string describing
							  data event,
			 LOGGER_SAMPLE_TYPE_LIST_ID -> integer containing
						       list ID number)
			(default is NULL)
	[sample_type]	type of sample specifier
			(LOGGER_SAMPLE_TYPE_NONE -> don't use the sample
						    specifier (default),
			 LOGGER_SAMPLE_TYPE_DATA_EVENT -> return data sampled
							  on a particular
							  data event,
			 LOGGER_SAMPLE_TYPE_LIST_ID -> return data from a
						       particular list)
	[sda_case]	SDA case to return data for (A value of
			LOGGER_ALL_SDA_CASES indicates that all cases
			should be returned.)
			(default is LOGGER_ALL_SDA_CASES)
	[sda_set]	SDA set to return data for (A value of
			LOGGER_ALL_SDA_SETS indicates that all sets
			should be returned.)
			(default is LOGGER_ALL_SDA_SETS)
	[sda_final_data] indicates whether or not to return only the
			 final data samples
			 (LOGGER_ANY_SDA_DATA -> return all SDA data values,
			  LOGGER_FINAL_SDA_DATA -> only return the final data
						   values (default))
	[options]	read options
			(LOGGER_OPT_NONE -> no options selected (default),
			 LOGGER_OPT_SAME_DI -> use the same device index for
					       all entries,
			 LOGGER_OPT_SAME_NODE -> use the same node for
						 all entries)
	[actual_nodes]	returned nodes actually used for data acquisition

	This function returns status values as follows:

	OK			success
	LJ_MEMFAIL		dynamic memory allocation failure
	positive value		number of devices in error
