status.i4.v = ip_address_to_acnet_node(ip_address.i1a.r, node.i4.r

	This routine will return the ACNET node corresponding to an IP address.

	ip_address	IP address or name
			(nnn.nnn.nnn.nnn or xxx.xxx.xxx.xxx)
	node		returned ACNET node (constants are in 'nodedefs')
	[was_expanded]	returned flag indicating whether or not the
			IP address had to be expanded to make a match
			(default is NULL)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_NO_SUCH		no information for the requested node exists
	CLIB_GENERIC_ERROR	error retrieving IP address information
	SQL_xxx			error retrieving node information from the
