Detailed Description

Definition in file cr_rule.c.

struct failure_route_rule* add_failure_route_rule	(	struct failure_route_rule **	frr_head,
		const str *	prefix,
		const str *	host,
		const str *	reply_code,
		flag_t	flags,
		flag_t	mask,
		const int	next_domain,
		const str *	comment
	)			`[read]`

prefix, host, reply_code, and comment must not contain NULL pointers.

Parameters:

	frr_head	pointer to the head of the failure route rule list, might be changed during insert
	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
	comment	a comment for the route rule

Returns:: pointer to the failure_route_rul struct on success, NULL on failure.

Here is the caller graph for this function:

prefix, rewrite_hostpart, rewrite_local_prefix, rewrite_local_suffix, and comment must not contain NULL pointers.

Parameters:

	rf	the current route_flags struct
	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 strip value of the rule
	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 NULL-termintated array of hash indices of the route for which this route is backup
	comment	a comment for the route rule
