Gio.SocketClient.connect_to_service

### Method

# Gio SocketClientconnect_to_service

since: 2.22

#### Declaration

    GSocketConnection*
    g_socket_client_connect_to_service (
      GSocketClient* client,
      const gchar* domain,
      const gchar* service,
      GCancellable* cancellable,
      GError** error
    )

#### Description

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.

Available since: 2.22

#### Parameters

`domain`

  Type: `const gchar*`

  A domain name.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`service`

  Type: `const gchar*`

  The name of the service to connect to.

  The data is owned by the caller of the method.
  The value is a NUL terminated UTF-8 string.

`cancellable`

  Type: `GCancellable`

  A `GCancellable`, or `NULL`.

  The argument can be `NULL`.
  The data is owned by the caller of the method.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the method if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `GSocketConnection`

A `GSocketConnection` if successful, or `NULL` on error.

The caller of the method takes ownership of the data, and is responsible for freeing it.
