Function Documentation

int add_failure_route_to_tree	(	struct dtrie_node_t *	failure_node,
		const str *	scan_prefix,
		const str *	full_prefix,
		const str *	host,
		const str *	reply_code,
		const flag_t	flags,
		const flag_t	mask,
		const int	next_domain,
		const str *	comment
	)

scan_prefix, host, reply_code, flags identifies the number for which the information is and the next_domain parameters defines where to continue routing in case of a match.

Parameters:

	failure_node	the root of the failure routing tree
	scan_prefix	the prefix for which to add the rule (must not contain non-digits)
	full_prefix	the whole scan prefix
	host	the hostname last tried
	reply_code	the reply code
	flags	user defined flags
	mask	mask for user defined flags
	next_domain	continue routing with this domain id
	comment	a comment for the route rule

Returns:: 0 on success, -1 on failure

	)

scan_prefix identifies the number for which the information is. The rewrite_* parameters define what to do in case of a match. prob gives the probability with which this rule applies if there are more than one for a given prefix.

Parameters:

	node	the root of the routing tree
	scan_prefix	the prefix for which to add the rule (must not contain non-digits)
	flags	user defined flags
	mask	mask for user defined flags
	full_prefix	the whole scan prefix
	max_targets	the number of targets
	prob	the weight of the rule
	rewrite_hostpart	the rewrite_host of the rule
	strip	the number of digits to be stripped off userpart before prepending prefix
	rewrite_local_prefix	the rewrite prefix
	rewrite_local_suffix	the rewrite suffix
	status	the status of the rule
	hash_index	the hash index of the rule
	backup	indicates if the route is backed up by another. only useful if status==0, if set, it is the hash value of another rule
	backed_up	an -1-termintated array of hash indices of the route for which this route is backup
	comment	a comment for the route rule
