get_download_server_node

	status.i4.v = read_device_download_file_c(node.i4.v, index.i4.v,
						  num_devices.i4.r,
						  device_indices.i4a.r,
						  properties.i2a.r)

	This routine read the list of device indices/properties from
	a node's download file.  If all arguments passed have a value
	of NULL, only the number of device/properties is returned.

	node		node of interest (constants are in 'nodedefs')
	index		index into node (At present, this is only used
			for CAMAC nodes where this is the crate number.
			A value of ALL_CAMAC_CRATES can be passed if
			all download devices associated with that node
			are desired.)
	num_devices	returned number of device/properties in the
			download file
	device_indices	returned device index or array of device indices
	properties	returned property or array of properties

	This function returns ACNET status values as follows:

	OK			success
	CLIB_NOTYET		requested node is not supported
	CLIB_INVARG		invalid index value passed
	FSHARE_xxx		error accessing download file

	This function requires the following include files:

	nodedefs_h, cbslib_h, acnet_errors_h
