#include <ldns/ldns.h>

ldns_pkt_section();

ldns_pkt_type();

DESCRIPTION

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;

};
