DESCRIPTION

42       ldns_pkt_edns() returns true if this packet needs and EDNS rr to be
43              sent.  At the moment the only reason is an expected packet size
44              larger than 512 bytes, but for instance dnssec would be a good
45              reason too.
46
47              packet: the packet to check
48              Returns true if packet needs edns rr
49
50       ldns_pkt_edns_udp_size() return the packet's edns udp size
51              packet: the packet
52              Returns the size
53
54       ldns_pkt_edns_extended_rcode() return the packet's edns extended rcode
55              packet: the packet
56              Returns the rcode
57
58       ldns_pkt_edns_version() return the packet's edns version
59              packet: the packet
60              Returns the version
61
62       ldns_pkt_edns_z() return the packet's edns z value
63              packet: the packet
64              Returns the z value
65
66       ldns_pkt_edns_data() return the packet's EDNS data
67              packet: the packet
68              Returns the data
69
70       ldns_pkt_set_edns_udp_size() Set the packet's edns udp size
71              packet: the packet
72              s: the size
73
74       ldns_pkt_set_edns_extended_rcode() Set the packet's edns extended rcode
75              packet: the packet
76              c: the code
77
78       ldns_pkt_set_edns_version() Set the packet's edns version
79              packet: the packet
80              v: the version
81
82       ldns_pkt_set_edns_z() Set the packet's edns z value
83              packet: the packet
84              z: the value
85
86       ldns_pkt_set_edns_data() Set the packet's EDNS data
87              packet: the packet
88              data: the data
