	This routine allows reading raw data from a list of devices
	whose total size can be larger than one ACNET packet.  The data
	can be read from a variety of data sources.  This routine provides
	only one shot data acquisition.

	device_indices	device index or array of device indices
	properties	property or array of properties
			(constants are in 'dbprops')
	raw_data	returned raw data
	errors		returned ACNET status value or array of values
	lengths		length in bytes or array of lengths
			(If a value of NULL is passed for this argument,
			 the database default lengths will be used.)
	offsets		offset in bytes or array of offsets
			(If a value of NULL is passed for this argument,
			 an offset of zero will be used for all devices.)
	atomic_lengths	smallest indivisible size of each device in bytes
			(If a value of NULL is passed for this argument,
			 the database default lengths will be used.)
	num_devices	number of devices
	data_source	source of the data
			(DIO_SOURCE_ACCELERATOR -> read live data,
			 DIO_SOURCE_DATABASE -> read the last setting stored
						in the database,
			 DIO_SOURCE_SAVERESTORE -> read data from save/restore,
			 DIO_SOURCE_SDA -> read data from SDA,
			 DIO_SOURCE_DATALOGGER -> read data from a lumberjack,
			 DIO_SOURCE_MEMORY -> read data from a memory pool)
	specs		data acquisition specifications depending on data source
			 DIO_SOURCE_DATABASE -> not used,
			 DIO_SOURCE_SAVERESTORE -> structure of type DIO_SR_SPEC,
			 DIO_SOURCE_SDA -> structure of type DIO_SDA_SPEC,
			 DIO_SOURCE_DATALOGGER-> structure of type DIO_DL_SPEC,
			 DIO_SOURCE_MEMORY -> structure of type DIO_MEMORY_SPEC)
	default_flags	flags indicating whether or not different
			parameters should all be treated the same
			(Note: These values can be logically 'OR'ed together
			 if more than one argument is to be defaulted.)
			(DIO_SAME_PI -> all devices will be requested
					using the first property,
			 DIO_SAME_LENGTH -> all devices will be requested
					    using the first length value,
			 DIO_SAME_OFFSET -> all devices will be requested
					    using the first offset value,
			 DIO_SAME_ATOMIC -> all devices will use the first
					    atomic length value)
	[ret_lengths]	actual returned length or array of lengths in bytes
			(default is NULL)

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid data source or file number
	DIO_MEMFAIL		memory allocation failure
	negative value		other ACNET format error
	positive value		number of first device in error

	This function requires the following include files:

	cnsparam_h, cbslib_h, dbprops_h, diolib_h, acnet_errors_h
