.SH DESCRIPTION
.HP
\fIldns_dnssec_verify_denial\fR()
denial is not just a river in egypt

\.br
\fBrr\fR: The (query) \%RR to check the denial of existence for
\.br
\fBnsecs\fR: The list of \%NSEC RRs that are supposed to deny the
existence of the \%RR
\.br
\fBrrsigs\fR: The \%RRSIG \%RR covering the \%NSEC RRs
\.br
Returns \%LDNS_STATUS_OK if the \%NSEC RRs deny the existence, error code
containing the reason they do not otherwise

\fIldns_dnssec_verify_denial_nsec3\fR()
Denial of existence using NSEC3 records
Since NSEC3 is a bit more complicated than normal denial, some
context arguments are needed

\.br
\fBrr\fR: The (query) \%RR to check the denial of existence for
\.br
\fBnsecs\fR: The list of NSEC3 RRs that are supposed to deny the
existence of the \%RR
\.br
\fBrrsigs\fR: The \%RRSIG rr covering the \%NSEC RRs
\.br
\fBpacket_rcode\fR: The \%RCODE value of the packet that provided the
NSEC3 RRs
\.br
\fBpacket_qtype\fR: The original query \%RR type
\.br
\fBpacket_nodata\fR: True if the providing packet had an empty \%ANSWER
section
\.br
Returns \%LDNS_STATUS_OK if the NSEC3 RRs deny the existence, error code
containing the reason they do not otherwise
