NAME

ldns_dnssec_zone, ldns_dnssec_name, ldns_dnssec_rrs, ldns_dnssec_rrsets - data structures

SYNOPSIS

#include <stdint.h>

#include <ldns/ldns.h>

       /**

        * Usually, the name is a pointer to the owner name of the first rr for

        * this name, but sometimes there is no actual data to point to,

        * for instance in

        * names representing empty nonterminals. If so, set alloced to true to

        * Names that contain other occluded rrsets and records with glue on
