Overview

ldns_pkt_edns() returns true if this packet needs and EDNS rr to be sent. At the moment the only reason is an expected packet size larger than 512 bytes, but for instance dnssec would be a good reason too.

.br packet: the packet to check .br Returns true if packet needs edns rr

ldns_pkt_edns_udp_size() return the packet's edns udp size .br packet: the packet .br Returns the size

ldns_pkt_edns_extended_rcode() return the packet's edns extended rcode .br packet: the packet .br Returns the rcode

ldns_pkt_edns_version() return the packet's edns version .br packet: the packet .br Returns the version

ldns_pkt_edns_z() return the packet's edns z value .br packet: the packet .br Returns the z value

ldns_pkt_edns_data() return the packet's EDNS data .br packet: the packet .br Returns the data

ldns_pkt_set_edns_udp_size() Set the packet's edns udp size .br packet: the packet .br s: the size

ldns_pkt_set_edns_extended_rcode() Set the packet's edns extended rcode .br packet: the packet .br c: the code

ldns_pkt_set_edns_version() Set the packet's edns version .br packet: the packet .br v: the version

ldns_pkt_set_edns_z() Set the packet's edns z value .br packet: the packet .br z: the value

ldns_pkt_set_edns_data() Set the packet's EDNS data .br packet: the packet .br data: the data
