The API will use the resource records in bundle_of_support_records to construct the validation chain and the DNSKEY or DS records in trust_anchor_records as trust anchors. The default list of trust anchor records that is used by the library to validate DNSSEC can be retrieved by using the getdns_root_trust_anchor helper function. .HP 3 .I utc_date_of_anchor time the trust anchors were obtained in epoch seconds (on success) .HP .SH "RETURN VALUES" Returns the default list of trust anchor records used by the library to validate DNSSEC or NULL if no default trust anchors are available. .SH EXAMPLES TBD .SH SEE ALSO .BR getdns_validate_dnssec (3) .BR libgetdns (3)
