## Detailed Description

Helper for connecting to a network service.

See Also
  SocketConnection, SocketListener

SocketClient is a high-level utility class for connecting to a network host using a connection oriented socket type.

You create a SocketClient object, set any options you want, then call a sync or async connect operation, which returns a SocketConnection subclass on success.

The type of the SocketConnection object returned depends on the type of the underlying socket that is in use. For instance, for a TCP/IP connection it will be a TcpConnection.

Since glibmm 2.24:

## Constructor & Destructor Documentation

virtual Gio::SocketClient::~SocketClient | ( |  | ) |

Gio::SocketClient::SocketClient | ( |  | ) |

protected

## Member Function Documentation

void Gio::SocketClient::add_application_proxy | ( | const Glib::ustring& | protocol | ) |

Enable proxy protocols to be handled by the application.

When the indicated proxy protocol is returned by the ProxyResolver, SocketClient will consider this protocol as supported but will not try to find a Proxy instance to handle handshaking. The application must check for this case by calling g_socket_connection_get_remote_address() on the returned SocketConnection, and seeing if it's a ProxyAddress of the appropriate type, to determine whether or not it needs to handle the proxy handshaking itself.

This should be used for proxy protocols that are dialects of another protocol such as HTTP proxy. It also allows cohabitation of proxy protocols that are reused between protocols. A good example is HTTP. It can be used to proxy HTTP, FTP and Gopher and can also be use as generic socket proxy through the HTTP CONNECT method.

When the proxy is detected as being an application proxy, TLS handshake will be skipped. This is required to let the application do the proxy specific handshake.

Parameters

  protocol | The proxy protocol.

Glib::RefPtr<SocketConnection> Gio::SocketClient::connect | ( | const Glib::RefPtr< SocketConnectable >& | connectable,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

Tries to resolve the connectable and make a network connection to it.

Upon a successful connection, a new SocketConnection is constructed and returned. The caller owns this new object and must drop their reference to it when finished with it.

The type of the SocketConnection object returned depends on the type of the underlying socket that is used. For instance, for a TCP/IP connection it will be a TcpConnection.

The socket created will be the same family as the address that the connectable resolves to, unless family is set with g_socket_client_set_family() or indirectly via g_socket_client_set_local_address(). The socket type defaults to SOCKET_TYPE_STREAM but can be set with g_socket_client_set_socket_type().

If a local address is specified with g_socket_client_set_local_address() the socket will be bound to this address before connecting.

Since glibmm 2.22:

Parameters

  connectable | A SocketConnectable specifying the remote address.
  cancellable | Optional Cancellable object, `0` to ignore.

Returns
  A SocketConnection on success, `0` on error.

Glib::RefPtr<SocketConnection> Gio::SocketClient::connect | ( | const Glib::RefPtr< SocketConnectable >& | connectable | ) |

void Gio::SocketClient::connect_async | ( | const Glib::RefPtr< SocketConnectable >& | connectable,
|  | const Glib::RefPtr< Cancellable >& | cancellable,
|  | const SlotAsyncReady& | slot
| ) |  |

This is the asynchronous version of g_socket_client_connect().

When the operation is finished callback will be called. You can then call g_socket_client_connect_finish() to get the result of the operation.

Since glibmm 2.22:

Parameters

  connectable | A SocketConnectable specifying the remote address.
  cancellable | A Cancellable, or `0`.
  callback | A AsyncReadyCallback.
  user_data | User data for the callback.

void Gio::SocketClient::connect_async | ( | const Glib::RefPtr< SocketConnectable >& | connectable,
|  | const SlotAsyncReady& | slot
| ) |  |

This is the asynchronous version of connect().

When the operation is finished slot will be called. You can then call finish() to get the result of the operation.

Parameters

  connectable | A SocketConnectable specifying the remote address.
  slot | A callback slot to call after the operation completes.

Glib::RefPtr<SocketConnection> Gio::SocketClient::connect_finish | ( | const Glib::RefPtr< AsyncResult >& | result | ) |

Finishes an async connect operation.

See g_socket_client_connect_async()

Since glibmm 2.22:

Parameters

  result | A AsyncResult.

Returns
  A SocketConnection on success, `0` on error.

Glib::RefPtr<SocketConnection> Gio::SocketClient::connect_to_host | ( | const Glib::ustring& | host_and_port,
|  | guint16 | default_port,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

This is a helper function for g_socket_client_connect().

Attempts to create a TCP connection to the named host.

host_and_port may be in any of a number of recognized formats; an IPv6 address, an IPv4 address, or a domain name (in which case a DNS lookup is performed). Quoting with [] is supported for all address types. A port override may be specified in the usual way with a colon. Ports may be given as decimal numbers or symbolic names (in which case an /etc/services lookup is performed).

If no port override is given in host_and_port then default_port will be used as the port number to connect to.

In general, host_and_port is expected to be provided by the user (allowing them to give the hostname, and a port override if necessary) and default_port is expected to be provided by the application.

In the case that an IP address is given, a single connection attempt is made. In the case that a name is given, multiple connection attempts may be made, in turn and according to the number of address records in DNS, until a connection succeeds.

Upon a successful connection, a new SocketConnection 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) `0` is returned and error (if non-`0`) is set accordingly.

Since glibmm 2.22:

Parameters

  host_and_port | The name and optionally port of the host to connect to.
  default_port | The default port to connect to.
  cancellable | A Cancellable, or `0`.

Returns
  A SocketConnection on success, `0` on error.

|  | const SlotAsyncReady& | slot
| ) |  |

See g_socket_client_connect_to_host_async()

Since glibmm 2.22:

Parameters

  result | A AsyncResult.

Returns
  A SocketConnection on success, `0` on error.

Glib::RefPtr<SocketConnection> Gio::SocketClient::connect_to_service | ( | const Glib::ustring& | domain,
|  | const Glib::ustring& | service,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

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 SocketConnection 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) `0` is returned and error (if non-`0`) is set accordingly.

Parameters

  domain | A domain name.
  service | The name of the service to connect to.
  cancellable | A Cancellable, or `0`.

Returns
  A SocketConnection if successful, or `0` on error.

Glib::RefPtr<SocketConnection> Gio::SocketClient::connect_to_service | ( | const Glib::ustring& | domain,

|  | guint16 | default_port,
|  | const Glib::RefPtr< Cancellable >& | cancellable
| ) |  |

This is a helper function for g_socket_client_connect().

Attempts to create a TCP connection with a network URI.

uri may be any valid URI containing an "authority" (hostname/port) component. If a port is not specified in the URI, default_port will be used. TLS will be negotiated if SocketClient::property_tls() is `true`. (SocketClient does not know to automatically assume TLS for certain URI schemes.)

Using this rather than g_socket_client_connect() or g_socket_client_connect_to_host() allows SocketClient to determine when to use application-specific proxy protocols.

Upon a successful connection, a new SocketConnection 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) `0` is returned and error (if non-`0`) is set accordingly.

Since glibmm 2.26:

Parameters

  uri | A network URI.
  default_port | The default port to connect to.
  cancellable | A Cancellable, or `0`.

Returns
  A SocketConnection on success, `0` on error.

  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy< SocketType > Gio::SocketClient::property_type | ( |  | ) |

The sockets type to use for socket construction.

void Gio::SocketClient::set_enable_proxy | ( | bool | enable | ) |

Sets whether or not client attempts to make connections via a proxy server.

When enabled (the default), SocketClient will use a ProxyResolver to determine if a proxy protocol such as SOCKS is needed, and automatically do the necessary proxy negotiation.

Since glibmm 2.26:

Parameters

  enable | Whether to enable proxies.

void Gio::SocketClient::set_family | ( | SocketFamily | family | ) |

Sets the socket family of the socket client.

If this is set to something other than SOCKET_FAMILY_INVALID then the sockets created by this object will be of the specified family.

This might be useful for instance if you want to force the local connection to be an ipv4 socket, even though the address might be an ipv6 mapped to ipv4 address.

Since glibmm 2.22:

Parameters

  family | A SocketFamily.

void Gio::SocketClient::set_local_address | ( | const Glib::RefPtr< SocketAddress >& | address | ) |

Sets the local address of the socket client.

The sockets created by this object will bound to the specified address (if not `0`) before connecting.

This is useful if you want to ensure that the local side of the connection is on a specific port, or on a specific interface.

Since glibmm 2.22:

Parameters

  address | A SocketAddress, or `0`.

void Gio::SocketClient::set_protocol | ( | SocketProtocol | protocol | ) |

Sets the protocol of the socket client.

The sockets created by this object will use of the specified protocol.

If protocol is %0 that means to use the default protocol for the socket family and type.

Since glibmm 2.22:

Parameters

  protocol | A SocketProtocol.

void Gio::SocketClient::set_socket_type | ( | SocketType | type | ) |

Sets the socket type of the socket client.

The sockets created by this object will be of the specified type.

It doesn't make sense to specify a type of SOCKET_TYPE_DATAGRAM, as GSocketClient is used for connection oriented services.

Since glibmm 2.22:

Parameters

  type | A SocketType.

void Gio::SocketClient::set_timeout | ( | guint | enable | ) |

Sets the I/O timeout for sockets created by client.

timeout is a time in seconds, or 0 for no timeout (the default).

The timeout value affects the initial connection attempt as well, so setting this may cause calls to g_socket_client_connect(), etc, to fail with IO_ERROR_TIMED_OUT.

Since glibmm 2.26:

Parameters

  timeout | The timeout.

A Glib::wrap() method for this object.

Parameters

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns
  A C++ instance that wraps this C instance.
