These functions can be used to parse hostnames to attempt to determine what part of the name belongs to the domain owner, and what part is simply a "public suffix" such as ".com".
const char * soup_tld_get_base_domain (const char *hostname,GError **error);
Finds the base domain for a given hostname. The base domain is
composed by the top level domain (such as .org, .com, .co.uk, etc)
plus the second level domain, for example for myhost.mydomain.com
it will return mydomain.com.
Note that NULL will be returned for private URLs (those not ending
with any well known TLD) because choosing a base domain for them
would be totally arbitrary.
This method only works for valid UTF-8 hostnames in their canonical
representation form, so you should use g_hostname_to_unicode() to
get the canonical representation if that is not the case.

gboolean            soup_tld_domain_is_public_suffix    (const char *domain);
Looks whether the domain passed as argument is a public domain
suffix (.org, .com, .co.uk, etc) or not.

representation form, so you should use g_hostname_to_unicode() to
get the canonical representation if that is not the case.

The GError domain for soup-tld-related errors.

| A hostname was syntactically invalid. | |
| The passed-in "hostname" was actually an IP address (and thus has no base domain or public suffix). | |
| The passed-in hostname
  did not have enough components. Eg, calling soup_tld_get_base_domain()on"co.uk". | |
| The passed-in hostname has no recognized public suffix. |
