## Detailed Description

A socket connection.

See Also
  IOStream, SocketClient, SocketListener

SocketConnection is a IOStream for a connected socket. They can be created either by SocketClient when connecting to a host, or by SocketListener when accepting a new client.

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

Chosing what type of object to construct is done with the socket connection factory, and it is possible for 3rd parties to register custom socket connection types for specific combination of socket family/type/protocol using g_socket_connection_factory_register_type().

## Member Function Documentation

static Glib::RefPtr<SocketConnection> Gio::SocketConnection::create | ( | const Glib::RefPtr< Socket >& | socket | ) |
| static

Since glibmm 2.22:

Returns
  A SocketConnection.

Glib::RefPtr<SocketAddress> Gio::SocketConnection::get_local_address | ( |  | ) |

Try to get the local address of a socket connection.

Since glibmm 2.22:

Returns
  A SocketAddress or `0` on error. Free the returned object with Glib::object_unref().

Glib::RefPtr<const SocketAddress> Gio::SocketConnection::get_local_address | ( |  | ) | const

Try to get the local address of a socket connection.

Since glibmm 2.22:

Returns
  A SocketAddress or `0` on error. Free the returned object with Glib::object_unref().

Glib::RefPtr<SocketAddress> Gio::SocketConnection::get_remote_address | ( |  | ) |

Try to get the remote address of a socket connection.

Since glibmm 2.22:

Returns
  A SocketAddress or `0` on error. Free the returned object with Glib::object_unref().

Glib::RefPtr<const SocketAddress> Gio::SocketConnection::get_remote_address | ( |  | ) | const

Try to get the remote address of a socket connection.

Since glibmm 2.22:

Returns
  A SocketAddress or `0` on error. Free the returned object with Glib::object_unref().

Glib::RefPtr<Socket> Gio::SocketConnection::get_socket | ( |  | ) |

Gets the underlying Socket object of the connection.

This can be useful if you want to do something unusual on it not supported by the SocketConnection APIs.

Since glibmm 2.22:

Returns
  A SocketAddress or `0` on error.

Glib::RefPtr<const Socket> Gio::SocketConnection::get_socket | ( |  | ) | const

Gets the underlying Socket object of the connection.

This can be useful if you want to do something unusual on it not supported by the SocketConnection APIs.

Since glibmm 2.22:

Returns
  A SocketAddress or `0` on error.

static GType Gio::SocketConnection::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

GSocketConnection* Gio::SocketConnection::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

const GSocketConnection* Gio::SocketConnection::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

GSocketConnection* Gio::SocketConnection::gobj_copy | ( |  | ) |

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Socket> > Gio::SocketConnection::property_socket | ( |  | ) | const

The underlying GSocket.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

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