#include <stdbool.h>

#include <ldns/ldns.h>

ldns_zone * ldns_zone_new(void);

void ldns_zone_free(ldns_zone *zone);

DESCRIPTION

ldns_zone: DNS Zone

A list of RR's with some
extra information which comes from the SOA RR
Note: nothing has been done to make this efficient (yet).
struct ldns_struct_zone
{
       the soa defines a zone:

       ldns_rr         *_soa;

       /* basically a zone is a list of rr's */

       ldns_rr_list    *_rrs;

       /* we could change this to be a -tree etc etc todo */

};
typedef struct ldns_struct_zone ldns_zone;

ldns_zone_new(): create a new ldns_zone structure .br Returns a pointer to a ldns_zone structure

ldns_zone_free(): Frees the allocated memory for the zone, and the rr_list structure in it .br zone: the zone to free

ldns_zone_deep_free(): Frees the allocated memory for the zone, the soa rr in it, and the rr_list structure in it, including the rr's in that. etc. .br zone: the zone to free

ldns_zone_new_frm_fp(): Create a new zone from a file .br z: the new zone .br *fp: the filepointer to use .br *origin: the zones' origin .br ttl: default ttl to use .br c: default class to use (IN)
.br Returns ldns_status mesg with an error or LDNS_STATUS_OK

ldns_zone_new_frm_fp_l(): Create a new zone from a file, keep track of the line numbering .br z: the new zone .br *fp: the filepointer to use .br *origin: the zones' origin .br ttl: default ttl to use .br c: default class to use (IN) .br line_nr: used for error msg, to get to the line number
.br Returns ldns_status mesg with an error or LDNS_STATUS_OK

ldns_zone_print(): Print a zone structure * to output. Note the SOA record is included in this output .br output: the fd to print to .br z: the zone to print

ldns_zone_print_fmt(): Print a zone structure * to output. Note the SOA record is included in this output .br output: the fd to print to .br fmt: format of the textual representation .br z: the zone to print
