Function Documentation

◆ ldns_zone_soa()

ldns_rr * ldns_zone_soa ( const ldns_zone * z)

Return the soa record of a zone.

Parameters
[in]zthe zone to read from
Returns
the soa record in the zone

Definition at line 17 of file zone.c.

References ldns_struct_zone::_soa.

◆ ldns_zone_rr_count()

size_t ldns_zone_rr_count ( const ldns_zone * z)

Returns the number of resource records in the zone, NOT counting the SOA record.

Parameters
[in]zthe zone to read from
Returns
the number of rr's in the zone

Definition at line 23 of file zone.c.

References ldns_struct_zone::_rrs, and ldns_rr_list_rr_count().

◆ ldns_zone_set_soa()

void ldns_zone_set_soa ( ldns_zone * z,
ldns_rr * soa )

Set the zone's soa record.

Parameters
[in]zthe zone to put the new soa in
[in]soathe soa to set

Definition at line 29 of file zone.c.

References ldns_struct_zone::_soa.

◆ ldns_zone_rrs()

ldns_rr_list * ldns_zone_rrs ( const ldns_zone * z)

Get a list of a zone's content.

Note that the SOA isn't included in this list. You need to get the with ldns_zone_soa.

Parameters
[in]zthe zone to read from
Returns
the rrs from this zone

Definition at line 35 of file zone.c.

References ldns_struct_zone::_rrs.

◆ ldns_zone_set_rrs()

void ldns_zone_set_rrs ( ldns_zone * z,
ldns_rr_list * rrlist )

Set the zone's contents.

Parameters
[in]zthe zone to put the new soa in
[in]rrlistthe rrlist to use

Definition at line 41 of file zone.c.

References ldns_struct_zone::_rrs.

◆ ldns_zone_push_rr_list()

signed char ldns_zone_push_rr_list ( ldns_zone * z,
const ldns_rr_list * list )

push an rrlist to a zone structure.

This function use pointer copying, so the rr_list structure inside z is modified!

Parameters
[in]zthe zone to add to
[in]listthe list to add
Returns
a true on success otherwise false

Definition at line 47 of file zone.c.

References ldns_rr_list_cat(), and ldns_zone_rrs().

◆ ldns_zone_push_rr()

signed char ldns_zone_push_rr ( ldns_zone * z,
ldns_rr * rr )

push an single rr to a zone structure.

This function use pointer copying, so the rr_list structure inside z is modified!

Parameters
[in]zthe zone to add to
[in]rrthe rr to add
Returns
a true on success otherwise false

Definition at line 53 of file zone.c.

References ldns_rr_list_push_rr(), and ldns_zone_rrs().

◆ ldns_zone_glue_rr_list()

ldns_rr_list * ldns_zone_glue_rr_list ( const ldns_zone * z)

Retrieve all resource records from the zone that are glue records.

The resulting list does are pointer references to the zone's data.

Due to the current zone implementation (as a list of rr's), this function is extremely slow. Another (probably better) way to do this is to use an ldns_dnssec_zone structure and the ldns_dnssec_mark_and_get_glue() function.

Parameters
[in]zthe zone to look for glue
Returns
the rr_list with the glue

◆ ldns_zone_new()

ldns_zone * ldns_zone_new ( void )

create a new ldns_zone structure

Returns
a pointer to a ldns_zone structure

ldns_rr_class c )

Create a new zone from a file.

Parameters
