The values are GETDNS_CONTEXT_NAMESPACE_DNS, GETDNS_CONTEXT_NAMESPACE_LOCALNAMES, GETDNS_CONTEXT_NAMESPACE_NETBIOS, GETDNS_CONTEXT_NAMESPACE_MDNS, and GETDNS_CONTEXT_NAMESPACE_NIS. When a normal lookup is done, the API does the lookups in the order given and stops when it gets the first result; a different method with the same result would be to run the queries in parallel and return when it gets the first result. Because lookups might be done over different mechanisms because of the different namespaces, there can be information leakage that is similar to that seen with getaddrinfo(). The default is determined by the OS.

.SH DESCRIPTION
|
||||
|
||||
.LP
|
||||
Names in DNS fields are stored in a fashion very different from the normal
|
||||
presentation format normally used in applications. The DNS format is described
|
||||
in the first paragraph in Section 3.1 of RFC 1035; the presentation format here
|
||||
is a null-terminated string with interior dots. These helper functions only
|
||||
work with names in the DNS format that are not compressed. They are useful for
|
||||
converting domain names in the replies_tree to and from the FQDN presentation
|
||||
format.
|
||||
|
||||
getdns_convert_dns_name_to_fqdn() converts a domain name in DNS format to the
|
||||
presentation format. For example, the hex sequence 03 77 77 77 07 65 78 61 6d
|
||||
70 6c 65 03 63 6f 6d 00 would be converted to "www.example.com".
|
||||
getdns_convert_fqdn_to_dns_name() does the reverse: it converts a
|
||||
null-terminated string in FQDN format to bytes in DNS format.
|
||||
|
||||
.HP 3
|
||||
.I dns_name_wire_fmt
|
||||
.RP
|
||||
The non-compressed DNS wire format name (per RFC 1035) in a bindata structure that
|
||||
will be converted to/from an fqdn. In getdns_convert_fqdn_to_dns_name storage is
|
||||
allocated using the system allocator (malloc) and must be freed by the caller.
|
||||
|
||||
.HP 3
|
||||
.I fqdn_as_string
|

.RP

||||
