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
	)

Adds the given failure route information to the failure prefix tree identified by failure_node. 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

int add_route_to_tree	(	struct dtrie_node_t *	node,
		const str *	scan_prefix,
		flag_t	flags,
		flag_t	mask,
		const str *	full_prefix,
		int	max_targets,
		double	prob,
		const str *	rewrite_hostpart,
		int	strip,
		const str *	rewrite_local_prefix,
		const str *	rewrite_local_suffix,
		int	status,
		int	hash_index,
		int	backup,
		int *	backed_up,
		const str *	comment
	)

Adds the given route information to the prefix tree identified by node. 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

Returns:: 0 on success, -1 on failure

int compare_domain_data	(	const void *	v1,
		const void *	v2
	)

Compares the IDs of two domain data structures. A NULL pointer is always greater than any ID.

Returns:: -1 if v1 < v2, 0 if v1 == v2, 1 if v1 > v2

struct domain_data_t* create_domain_data	(	int	domain_id,
		str *	domain_name
	)			`[read]`

Create a new domain in shared memory and set it up.

Parameters:

	domain_id	the id of the domain
	domain_name	the name of the domain

Returns:: a pointer to the newly allocated domain data or NULL on error, in which case it LOGs an error message.
