## DESCRIPTION

*ldns\_dnssec\_zone\_find\_rrset*() Find the RRset with the given name and type in the zone

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

*ldns\_dnssec\_zone\_new*() Creates a new dnssec\_zone structure .br 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 .br **\*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

.br **zone**: the zone to add the RR to .br **rr**: The RR to add .br Returns LDNS\_STATUS\_OK on success and LDNS\_STATUS\_EQUAL\_ERR when and RR with equal ownername, class, type and rdata already exists, and an error code otherwise

*ldns\_dnssec\_zone\_names\_print*() Prints the rbtree of ldns\_dnssec\_name structures to the file descriptor

.br **out**: the file descriptor to print the names to .br **tree**: the tree of ldns\_dnssec\_name structures to print .br **print\_soa**: if true, print SOA records, if false, skip them

*ldns\_dnssec\_zone\_print*() Prints the complete zone to the given file descriptor

.br **out**: the file descriptor to print to .br **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)

.br **zone**: the zone to check for empty nonterminals return LDNS\_STATUS\_OK on success.
