SYNOPSIS

DESCRIPTION

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. packet: the packet to check Returns true if packet needs edns rr ldns_pkt_edns_udp_size() return the packet's edns udp size packet: the packet Returns the size ldns_pkt_edns_extended_rcode() return the packet's edns extended rcode packet: the packet Returns the rcode ldns_pkt_edns_version() return the packet's edns version packet: the packet Returns the version ldns_pkt_edns_z() return the packet's edns z value packet: the packet Returns the z value ldns_pkt_edns_data() return the packet's edns data packet: the packet Returns the data ldns_pkt_set_edns_udp_size() Set the packet's edns udp size packet: the packet s: the size ldns_pkt_set_edns_extended_rcode() Set the packet's edns extended rcode packet: the packet c: the code ldns_pkt_set_edns_version() Set the packet's edns version packet: the packet v: the version ldns_pkt_set_edns_z() Set the packet's edns z value packet: the packet z: the value ldns_pkt_set_edns_data() Set the packet's edns data packet: the packet data: the data
