DESCRIPTION

24       ldns_dnssec_verify_denial() denial is not just a river in egypt
25
26              rr: The (query) RR to check the denial of existence for
27              nsecs: The list of NSEC RRs that are supposed to deny the exis‐
28              tence of the RR
29              rrsigs: The RRSIG RR covering the NSEC RRs
30              Returns LDNS_STATUS_OK if the NSEC RRs deny the existence, error
31              code containing the reason they do not otherwise
32
33       ldns_dnssec_verify_denial_nsec3() Denial of existence using NSEC3
34              records Since NSEC3 is a bit more complicated than normal
35              denial, some context arguments are needed
36
37              rr: The (query) RR to check the denial of existence for
38              nsecs: The list of NSEC3 RRs that are supposed to deny the exis‐
39              tence of the RR
40              rrsigs: The RRSIG rr covering the NSEC RRs
41              packet_rcode: The RCODE value of the packet that provided the
42              NSEC3 RRs
43              packet_qtype: The original query RR type
44              packet_nodata: True if the providing packet had an empty ANSWER
45              section
46              Returns LDNS_STATUS_OK if the NSEC3 RRs deny the existence,
47              error code containing the reason they do not otherwise
