ldns\_axfr\_start, ldns\_axfr\_next, ldns\_axfr\_abort, ldns\_axfr\_complete, ldns\_axfr\_last\_pkt - functions for full zone transfer

# [SYNOPSIS](#SYNOPSIS)

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

#include <ldns/ldns.h>

ldns\_status ldns\_axfr\_start(ldns\_resolver \*resolver, const ldns\_rdf \*domain, ldns\_rr\_class c);

ldns\_rr* ldns\_axfr\_next(ldns\_resolver \*resolver);

void ldns\_axfr\_abort(ldns\_resolver \*resolver);

bool ldns\_axfr\_complete(const ldns\_resolver \*resolver);

ldns\_pkt* ldns\_axfr\_last\_pkt(const ldns\_resolver \*res);

# [DESCRIPTION](#DESCRIPTION)

*ldns\_axfr\_start*() Prepares the resolver for an axfr query The query is sent and the answers can be read with ldns\_axfr\_next  
**resolver**: the resolver to use  
**domain**: the domain to axfr  
**c**: the class to use  
Returns ldns\_status the status of the transfer

*ldns\_axfr\_next*() Get the next stream of RRs in a AXFR  
**resolver**: the resolver to use. First ldns\_axfr\_start() must be called  
Returns ldns\_rr the next RR from the AXFR stream After you get this returned RR (not NULL: on error), then check if ldns\_axfr\_complete() is true to see if the zone transfer has completed.

*ldns\_axfr\_abort*() Abort a transfer that is in progress  
**resolver**: the resolver that is used

*ldns\_axfr\_complete*() Returns true if the axfr transfer has completed (i.e. 2 SOA RRs and no errors were encountered  
**resolver**: the resolver that is used  
Returns bool true if axfr transfer was completed without error

*ldns\_axfr\_last\_pkt*() Returns a pointer to the last ldns\_pkt that was sent by the server in the AXFR transfer usable for instance to get the error code on failure  
**res**: the resolver that was used in the axfr transfer  
Returns ldns\_pkt the last packet sent
