DESCRIPTION

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