status.i4.v = dio_documentation_info_c(device_indices.i4a.r,
					       errors.i2a.r, num_devices.i4.v)

	This routine returns the documentation information for a device.
	If "num_devices" is specified, documentation information for
	a list of devices can be retrieved.

	device_indices	device index or array of device indices
	document_data	returned documentation information or array of
			documentation information
			(structure of type DIO_DOCUMENT_DEVICE_DATA)
			(A value of NULL can be passed for this argument if
			 only caching of the documentation information
			 is desired.)
	errors		returned ACNET status value or array of status values
	num_devices	number of devices

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid number of devices passed
	DIO_MEMFAIL		memory allocation failure
	negative value		ACNET format error indicating overall failure
	positive value		number of devices in error indicating partial

	This function requires the following include files:

	diolib_h, acnet_errors_h
