* g_socket_client_connect_to_service:

* @domain: a domain name
* @service: the name of the service to connect to
* @cancellable: a #GCancellable, or %NULL
* @error: a pointer to a #GError, or %NULL
* @returns: a #GSocketConnection if successful, or %NULL on error
*
* Attempts to create a TCP connection to a service.
*
* This call looks up the SRV record for @service at @domain for the
* "tcp" protocol. It then attempts to connect, in turn, to each of
* the hosts providing the service until either a connection succeeds
* or there are no hosts remaining.
*
* Upon a successful connection, a new #GSocketConnection is constructed
* and returned. The caller owns this new object and must drop their
* reference to it when finished with it.
*
* In the event of any failure (DNS error, service not found, no hosts
* connectable) %NULL is returned and @error (if non-%NULL) is set
* accordingly.
