21 ldns_pkt
22 DNS packet
23 This structure contains a complete DNS packet (either a query or
25 an answer)
26 It is the complete representation of what you actually send to a
28 nameserver, and what it sends back (assuming you are the client
29 here).
30 struct ldns_struct_pkt
31 {
32 Header section:
33 ldns_hdr *_header;
34 /* extra items needed in a packet */
35 an rdf (A or AAAA) with the IP address of the server it is
36 from:
37 ldns_rdf *_answerfrom;
38 Timestamp of the time the packet was sent or created:
39 struct timeval timestamp;
40 The duration of the query this packet is an answer to:
41 uint32_t _querytime;
42 The size of the wire format of the packet in octets:
43 size_t _size;
44 Optional tsig rr:
45 ldns_rr *_tsig_rr;
46 EDNS0 available buffer size, see RFC2671:
47 uint16_t _edns_udp_size;
48 EDNS0 Extended rcode:
49 uint8_t _edns_extended_rcode;
50 EDNS Version:
51 uint8_t _edns_version;
52 /* OPT pseudo-RR presence flag */
53 uint8_t _edns_present;
54 Reserved EDNS data bits:
55 uint16_t _edns_z;
56 Arbitrary EDNS rdata:
57 ldns_rdf *_edns_data;
58 Structed EDNS data:
59 ldns_edns_option_list *_edns_list;
60 Question section:
61 ldns_rr_list *_question;
62 Answer section:
63 ldns_rr_list *_answer;
