status.i4.v = logger_log_control_values_c(node.i4.v, num_devices.i4.v,
						  commands.i4a.r, errors.i2a.r,
	This routine logs basic control values for a list of devices.

	node		node to log data in (constants are in 'nodedefs')
	num_devices	number of devices to log
	timestamp	timestamp value to log data at
			(seconds since January 1, 1970 UTC)
	device_names	device names to log
			(LONG_DEVICE_NAME_LEN characters per device)
			(examples: "M:OUTTMP", "T-HA11>2", "T_HA11[2]")
	commands	array of basic control commands to log
			(DIO_RESET_COMMAND -> reset a device
			 DIO_ON_COMMAND -> turn on a device,
			 DIO_OFF_COMMAND -> turn off a device,
			 DIO_POS_COMMAND -> positive polarity,
			 DIO_NEG_COMMAND -> negative polarity,
			 DIO_RAMP_COMMAND -> ramp command,
			 DIO_DC_COMMAND -> DC command)
	errors		returned device errors
	options		logging options (not used)

	This function returns ACNET status values as follows:

	OK			success
	LJ_INVARG		invalid number of devices, invalid command,
				or nonstatus property encountered
	LJ_MEMFAIL		dynamic memory allocation failure
	DIO_NOATT		missing basic control or status attribute
	ACNET_xxx		error in communicating with Lumberjack

	This function requires the following include files:

	nodedefs_h, clib_h, acnet_errors_h
