(

struct iter_priv *

priv

)

Delete priv structure.

Parameters:

priv,:

to delete.

int priv_apply_cfg	(	struct iter_priv *	priv,
		struct config_file *	cfg
	)

Process priv config.

Parameters:

priv,:	where to store.
cfg,:	config options.

Returns:

0 on error.

int priv_rrset_bad	(	struct iter_priv *	priv,
		ldns_buffer *	pkt,
		struct rrset_parse *	rrset
	)

See if rrset is bad.

Parameters:

priv,:	structure for private address storage.
pkt,:	packet to decompress rrset name in.
rrset,:	the rrset to examine, A or AAAA.

Returns:

true if the rrset is bad and should be removed.
