NAME

ldns_pkt_new, ldns_pkt_free, ldns_pkt_print, ldns_pkt_query_new, ldns_pkt_query_new_frm_str, ldns_pkt_reply_type - ldns_pkt creation, destruction and printing

SYNOPSIS

#include <stdint.h>
#include <stdbool.h>

#include <ldns/ldns.h>

ldns_pkt* ldns_pkt_new(void);

void ldns_pkt_free(ldns_pkt *packet);

void ldns_pkt_print(FILE *output, const ldns_pkt *pkt);

ldns_pkt* ldns_pkt_query_new(ldns_rdf *rr_name, ldns_rr_type rr_type, ldns_rr_class rr_class, uint16_t flags);

ldns_status ldns_pkt_query_new_frm_str(ldns_pkt **p, const char *rr_name, ldns_rr_type rr_type, ldns_rr_class rr_class , uint16_t flags);

ldns_pkt_type ldns_pkt_reply_type(const ldns_pkt *p);

DESCRIPTION

ldns_pkt_new(): allocates and initializes a ldns_pkt structure. .br Returns pointer to the new packet

ldns_pkt_free(): frees the packet structure and all data that it contains. .br packet: The packet structure to free .br Returns void

ldns_pkt_print(): Prints the data in the DNS packet to the given file stream (in presentation format)
.br output: the file stream to print to .br pkt: the packet to print .br Returns void

ldns_pkt_query_new(): creates a packet with a query in it for the given name, type and class. .br 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. .br rr_type: the type to query for .br rr_class: the class to query for .br flags: packet flags .br 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. .br p: the packet to be returned .br rr_name: the name to query for (as string) .br rr_type: the type to query for .br rr_class: the class to query for .br flags: packet flags .br 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. .br p: the packet to examine .br Returns the type of packet
