Function Documentation

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.

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().

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.

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.

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.

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 succes otherwise falsed

Definition at line 47 of file zone.c.

References ldns_rr_list_cat(), and ldns_zone_rrs().

bool 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 succes otherwise falsed

Definition at line 54 of file zone.c.

References ldns_rr_list_push_rr(), and ldns_zone_rrs().

ldns_rr_list* ldns_zone_strip_glue_rrs ( const ldns_rdf zone_name,
const ldns_rr_list rrs,
ldns_rr_list glue_rrs 
)

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

Returns:
a pointer to a ldns_zone structure
