ldns_pkt DNS packet This structure contains a complete DNS packet (either a query or an answer) It is the complete representation of what you actually send to a nameserver, and what it sends back (assuming you are the client here). struct ldns_struct_pkt { Header section: ldns_hdr *_header; /* extra items needed in a packet */ an rdf (A or AAAA) with the IP address of the server it is from: ldns_rdf *_answerfrom; Timestamp of the time the packet was sent or created: struct timeval timestamp; The duration of the query this packet is an answer to: uint32_t _querytime; The size of the wire format of the packet in octets: size_t _size; Optional tsig rr: ldns_rr *_tsig_rr; EDNS0 available buffer size, see RFC2671: uint16_t _edns_udp_size; EDNS0 Extended rcode: uint8_t _edns_extended_rcode; EDNS Version: uint8_t _edns_version; /* OPT pseudo-RR presence flag */ uint8_t _edns_present; Reserved EDNS data bits: uint16_t _edns_z; Arbitrary EDNS rdata: ldns_rdf *_edns_data; Question section: ldns_rr_list *_question; Answer section: ldns_rr_list *_answer; Authority section: ldns_rr_list *_authority; Additional section: ldns_rr_list *_additional; }; typedef struct ldns_struct_pkt ldns_pkt; ldns_pkt_section() ldns_pkt_type()
