DESCRIPTION

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 presentation 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 ownership 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
