acnet_check_if_handle_is_available

	status.i4.v = acnet_check_if_handle_is_available(net_handle.i1a.r
							 [,node_name.i1a.r])

	This routine checks to see if an ACNET handle is available.

	net_handle	network handle to check
			(PROCESS_NAME_LEN characters)
	[node_name]	virtual node name
			(default is NULL which results in using the
			 default ACNET node for the caller's computer)

	This function returns ACNET status values as follows:

	OK			ACNET handle is available
	ACNET_NAME_IN_USE	ACNET handle is in use

	This function requires the following include files:

	cnsparam_h, acnet_h, acnet_errors_h
