scope_set_trace_length_c (ul_scopes)

	status.i4.v = scope_set_trace_length_c(connect_info.g.v,
					       trace_length.i4.v)

	This routine sets the trace length for a scope.

	connect_info	scope connection structure created by a
			prior call to scope_connect
	trace_length	desired trace length (number of points)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_NOTYET		scope model is not supported
	CLIB_INVARG		invalid connection information passed
	CLIB_GENERIC_ERROR	error setting scope information
	otherwise		other ACNET error

	This function requires the following include files:

	ul_scopes_h:scopelib_h, acnet_errors_h

	Related functions:

	tds7000_set_trace_length_c, scope_connect, scope_disconnect, scope_info

	C/C++ usage:

	static const char	ip_name[] = "myscope.fnal.gov";
	int	status;
	int	trace_length = TRACE_LENGTH;
	void	*connect_info;

	status = scope_connect(ip_name,&connect_info);

	status = scope_set_trace_length_c(connect_info,trace_length);

	status = scope_disconnect(&connect_info);
