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
