| typedef | ISC_LIST (struct dns_forwarder) dns_forwarderlist_t |
| isc_result_t | dns_fwdtable_create (isc_mem_t *mctx, dns_fwdtable_t **fwdtablep) |
| Creates a new forwarding table. | |
| isc_result_t | dns_fwdtable_addfwd (dns_fwdtable_t *fwdtable, dns_name_t *name, dns_forwarderlist_t *fwdrs, dns_fwdpolicy_t policy) |
| isc_result_t | dns_fwdtable_add (dns_fwdtable_t *fwdtable, dns_name_t *name, isc_sockaddrlist_t *addrs, dns_fwdpolicy_t policy) |
| Adds an entry to the forwarding table. The entry associates a domain with a list of forwarders and a forwarding policy. The addrs/fwdrs list is copied if not empty, so the caller should free its copy. | |
| isc_result_t | dns_fwdtable_delete (dns_fwdtable_t *fwdtable, dns_name_t *name) |
| Removes an entry for 'name' from the forwarding table. If an entry that exactly matches 'name' does not exist, ISC_R_NOTFOUND will be returned. | |
| isc_result_t | dns_fwdtable_find (dns_fwdtable_t *fwdtable, dns_name_t *name, dns_forwarders_t **forwardersp) |
| Finds a domain in the forwarding table. The closest matching parent domain is returned. | |
| isc_result_t | dns_fwdtable_find2 (dns_fwdtable_t *fwdtable, dns_name_t *name, dns_name_t *foundname, dns_forwarders_t **forwardersp) |
| Finds a domain in the forwarding table. The closest matching parent domain is returned. | |
| void | dns_fwdtable_destroy (dns_fwdtable_t **fwdtablep) |
| Destroys a forwarding table. | |
