ldns_pkt_new() allocates and initializes a ldns_pkt structure. Returns pointer to the new packet ldns_pkt_free() frees the packet structure and all data that it contains. packet: The packet structure to free Returns void ldns_pkt_print() Prints the data in the DNS packet to the given file stream (in presenta‐ tion format) output: the file stream to print to pkt: the packet to print Returns void ldns_pkt_query_new() creates a packet with a query in it for the given name, type and class. rr_name: the name to query for (not copied). The returned packet will take owner‐ ship of rr_name, so the caller should not free it. rr_type: the type to query for rr_class: the class to query for flags: packet flags Returns ldns_pkt* a pointer to the new pkt ldns_pkt_query_new_frm_str() creates a query packet for the given name, type, class. p: the packet to be returned rr_name: the name to query for (as string) rr_type: the type to query for rr_class: the class to query for flags: packet flags Returns LDNS_STATUS_OK or a ldns_status mesg with the error ldns_pkt_reply_type() looks inside the packet to determine what kind of packet it is, AUTH, NXDOMAIN, REFERRAL, etc. p: the packet to examine Returns the type of packet
