status.i4.v = acnet_trunk_node_exists_in_db_c(node.i4.v

	This routine determines if an ACNET trunk and node exists
	in the database.  A value of NULL can be passed for returned
	arguments which are not needed.

	node		ACNET trunk and node to check for
			(constants are in 'nodedefs')
	[node_name]	returned corresponding null terminated node name
			(allow NODE_NAME_LEN + 1 characters)
	[db_status]	returned ACNET status of node database access

	This function returns ACNET status values as follows:

	TRUE			trunk and node exists in the database
	FALSE			trunk and node does not exist in the database

	This function requires the following include files:

	cnsparam_h, cbslib_h, nodedefs_h, acnet_errors_h

	C/C++ usage:

	char	node_name[NODE_NAME_LEN_LEN+1];
	int	status;
	int	node = MI1;
	int	db_status;

	status = acnet_trunk_node_exists_in_db_c(node,node_name,&db_status);
