Top Level Domain utils

Top Level Domain utils — Top-Level Domain Utilities

Types and Values

Object Hierarchy


Includes

#include <libsoup/soup.h>

Description

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".

Functions

soup_tld_get_base_domain ()

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.

Prior to libsoup 2.46, this function required that hostname be in UTF-8 if it was an IDN. From 2.46 on, the name can be in either UTF-8 or ASCII format (and the return value will be in the same format).

Parameters

hostname

a hostname

 

error

return location for a GError, or NULL to ignore errors. See SoupTLDError for the available error codes

 

Returns

a pointer to the start of the base domain in hostname . If an error occurs, NULL will be returned and error set.

Since 2.40


soup_tld_domain_is_public_suffix ()

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.

Prior to libsoup 2.46, this function required that domain be in UTF-8 if it was an IDN. From 2.46 on, the name can be in either UTF-8 or ASCII format (and the return value will be in the same format).

Parameters

domain

a domain name

 

Returns

TRUE if it is a public domain, FALSE otherwise.

Since 2.40

Types and Values

SOUP_TLD_ERROR

#define SOUP_TLD_ERROR soup_tld_error_quark()

The GError domain for soup-tld-related errors.

Since 2.40


enum SoupTLDError

Error codes for SOUP_TLD_ERROR.

Members

SOUP_TLD_ERROR_INVALID_HOSTNAME

A hostname was syntactically invalid.

 

SOUP_TLD_ERROR_IS_IP_ADDRESS

The passed-in "hostname" was actually an IP address (and thus has no base domain or public suffix).

 

SOUP_TLD_ERROR_NOT_ENOUGH_DOMAINS

The passed-in hostname did not have enough components. Eg, calling soup_tld_get_base_domain() on "co.uk".

 

SOUP_TLD_ERROR_NO_BASE_DOMAIN

The passed-in hostname has no recognized public suffix.

 

Since 2.40
