SYNOPSIS

       #include <stdint.h>
       #include <stdbool.h>

       #include <ldns/ldns.h>

       ldns_status ldns_dnssec_verify_denial(ldns_rr *rr, ldns_rr_list *nsecs,
       ldns_rr_list *rrsigs);

       ldns_status ldns_dnssec_verify_denial_nsec3(ldns_rr  *rr,  ldns_rr_list

       packet_qtype, bool packet_nodata);

DESCRIPTION

       ldns_dnssec_verify_denial() denial is not just a river in egypt

              rr: The (query) RR to check the denial of existence for
              nsecs: The list of NSEC RRs that are supposed to deny the
                               existence of the RR
              rrsigs: The RRSIG RR covering the NSEC RRs
              Returns LDNS_STATUS_OK if the NSEC RRs deny the existence, error
              code
                                     containing   the   reason   they  do  not
              otherwise

       ldns_dnssec_verify_denial_nsec3()  Denial  of  existence  using   NSEC3
              records  Since  NSEC3  is  a  bit  more  complicated than normal
              denial, some context arguments are needed

              rr: The (query) RR to check the denial of existence for
              nsecs: The list of NSEC3 RRs that are supposed to deny the
                               existence of the RR
              rrsigs: The RRSIG rr covering the NSEC RRs
              packet_rcode: The RCODE value of the packet that provided the
                                      NSEC3 RRs
              packet_qtype: The original query RR type
              packet_nodata: True if the providing packet had an empty ANSWER
                                       section
              Returns LDNS_STATUS_OK if the  NSEC3  RRs  deny  the  existence,
              error code
                                     containing   the   reason   they  do  not
              otherwise
