ldns_dnssec_zone_find_rrset() Find the RRset with the given name and type in the zone

zone: the zone structure to find the RRset in
dname: the domain name of the RRset to find
type: the type of the RRset to find
Returns the RRset, or NULL if not present

ldns_dnssec_zone_new() Creates a new dnssec_zone structure
Returns the allocated structure

ldns_dnssec_zone_free() Frees the given zone structure, and its rbtree of dnssec_names Individual ldns_rr RRs within those names are *not* freed
*zone: the zone to free

ldns_dnssec_zone_add_rr() Adds the given RR to the zone. It find whether there is a dnssec_name with that name present. If so, add it to that, if not create a new one. Special handling of NSEC and RRSIG provided

zone: the zone to add the RR to
rr: The RR to add
Returns LDNS_STATUS_OK on success, an error code otherwise

ldns_dnssec_zone_names_print() Prints the rbtree of ldns_dnssec_name structures to the file descriptor

out: the file descriptor to print the names to
tree: the tree of ldns_dnssec_name structures to print
print_soa: if true, print SOA records, if false, skip them

ldns_dnssec_zone_print() Prints the complete zone to the given file descriptor

out: the file descriptor to print to
zone: the dnssec_zone to print

ldns_dnssec_zone_add_empty_nonterminals() Adds explicit dnssec_name structures for the empty nonterminals in this zone. (this is needed for NSEC3 generation)

zone: the zone to check for empty nonterminals return LDNS_STATUS_OK on success.
