.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
|
|
a null terminated string to be converted to/from non-compressed DNS wire format name (per RFC 1035).
|
|
In getdns_convert_dns_name_to_fqdn storage is
|
|
allocated using the system allocator (malloc) and must be freed by the caller.
