* g_socket_listener_add_address:
* @listener: a #GSocketListener
* @address: a #GSocketAddress
* @type: a #GSocketType
* @protocol: a #GSocketProtocol
* @source_object: (allow-none): Optional #GObject identifying this source
* @effective_address: (out) (allow-none): location to store the address that was bound to, or %NULL.
* @error: #GError for error reporting, or %NULL to ignore.
*
* Creates a socket of type @type and protocol @protocol, binds
* it to @address and adds it to the set of sockets we're accepting
* sockets from.
*
* Note that adding an IPv6 address, depending on the platform,
* may or may not result in a listener that also accepts IPv4
* connections. For more deterministic behavior, see
* g_socket_listener_add_inet_port().
*
* @source_object will be passed out in the various calls
* to accept to identify this particular source, which is
* useful if you're listening on multiple addresses and do
* different things depending on what address is connected to.
*
* If successful and @effective_address is non-%NULL then it will
* be set to the address that the binding actually occurred at. This
* is helpful for determining the port number that was used for when
* requesting a binding to port 0 (ie: "any port"). This address, if
* requested, belongs to the caller and must be freed.
*
* Returns: %TRUE on success, %FALSE on error.
*
* Since: 2.22
