rtd720_get_id_string_c (ul_scopes)

	status.i4.v = rtd720_get_id_string_c(connect_info.g.v,

	This routine retrieves the ID string for an RTD720
	series scope.

	connect_info	scope connection structure created by a
			prior call to scope_connect
	max_return	maximum number of characters to return
	id_string	returned null-terminated ID string

	This function returns ACNET status values as follows:

	OK			success
	CLIB_INVARG		invalid connection information passed
	CLIB_GENERIC_ERROR	error accessing scope information
	otherwise		other ACNET error

	This function requires the following include files:

	ul_scopes_h:scopelib_h, ul_scopes_h:tekdefs_h, acnet_errors_h

	C/C++ usage:

	static const char	ip_name[] = "node_address.fnal.gov";
	char	id_string[MAX_RETURN+1];
	int	status;
	int	max_return = MAX_RETURN;
	void	*connect_info;

	status = scope_connect(ip_name,&connect_info);

	status = rtd720_get_id_string_c(connect_info,max_return,id_string);

	status = scope_disconnect(&connect_info);
