Soup.tld_get_base_domain
Description: Reference for Soup.tld_get_base_domain

### Function

# Souptld_get_base_domain

#### Declaration [src]

    const char*
    soup_tld_get_base_domain (
      const char* hostname,
      GError** error
    )

#### Description [src]

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` | `const char*`
| A hostname.
| The data is owned by the caller of the function.
| The value is a NUL terminated UTF-8 string.
`error` | `GError **`
| The return location for a `GError*`, or `NULL`.

#### Return value

Returns: | `const char*`
| A pointer to the start of the base domain in `hostname`. If an error occurs, `NULL` will be returned and `error` set.
| The data is owned by the called function.
| The value is a NUL terminated UTF-8 string.
