[in]	zone	the zone to add the RR to
[in]	rr	The RR to add

Returns: LDNS_STATUS_OK on success, an error code otherwise

◆ ldns_dnssec_zone_add_empty_nonterminals()

ldns_status ldns_dnssec_zone_add_empty_nonterminals ( ldns_dnssec_zone * zone )

Adds explicit dnssec_name structures for the empty nonterminals in this zone.

(this is needed for NSEC3 generation)

Parameters

[in] zone the zone to check for empty nonterminals return LDNS_STATUS_OK on success.

◆ ldns_dnssec_zone_is_nsec3_optout()

signed char ldns_dnssec_zone_is_nsec3_optout ( const ldns_dnssec_zone * zone )

If a NSEC3PARAM is available in the apex, walks the zone and returns true on the first optout nsec3.

Parameters

[in] zone the zone to check for nsec3 optout records return true when the zone has at least one nsec3 optout record.
