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

bool Gio::SocketConnection::connect ( const Glib::RefPtr< SocketAddress >&  address,
const Glib::RefPtr< Cancellable >&  cancellable 
)

Connect connection to the specified remote address.

Since glibmm 2.32:
Parameters
addressA SocketAddress specifying the remote address.
cancellableA Cancellable or nullptr.
Returns
true if the connection succeeded, false on error.
Exceptions
Glib::Error
bool Gio::SocketConnection::connect ( const Glib::RefPtr< SocketAddress >&  address)

A connect() convenience overload.

void Gio::SocketConnection::connect_async ( const Glib::RefPtr< SocketAddress >&  address,
const SlotAsyncReady &  slot,
const Glib::RefPtr< Cancellable >&  cancellable 
)

Asynchronously connect this connection to the specified remote address.

This clears the "blocking" flag on this connection's underlying socket if it is currently set.

Use connect_finish() to retrieve the result.

Parameters
addressA SocketAddress specifying the remote address.
slotA SlotAsyncReady slot.
cancellableA Cancellable.
Since glibmm 2.36:
void Gio::SocketConnection::connect_async ( const Glib::RefPtr< SocketAddress >&  address,
const SlotAsyncReady &  slot 
)

A non-cancellable version of connect_async().

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

Gets the result of a g_socket_connection_connect_async() call.

Since glibmm 2.32:
Parameters
resultThe AsyncResult.
Returns
true if the connection succeeded, false on error.
Exceptions
Glib::Error
static Glib::RefPtr<SocketConnection> Gio::SocketConnection::create ( const Glib::RefPtr< Socket >&  socket)
static

Creates a SocketConnection subclass of the right type for socket.

Since glibmm 2.22:
Parameters
socketA Socket.
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 nullptr on error. Free the returned object with Glib::object_unref().
Exceptions
Glib::Error
Glib::RefPtr<const SocketAddress> Gio::SocketConnection::get_local_address ( ) const

Try to get the local address of a socket connection.

Since glibmm 2.22:

Exceptions
Glib::Error
Glib::RefPtr<SocketAddress> Gio::SocketConnection::get_remote_address ( )

Try to get the remote address of a socket connection.

Since GLib 2.40, when used with g_socket_client_connect() or g_socket_client_connect_async(), during emission of Gio::SocketClientEvent::CONNECTING, this function will return the remote address that will be used for the connection. This allows applications to print e.g. "Connecting to example.com (10.42.77.3)...".

Since glibmm 2.22:
Returns
A SocketAddress or nullptr on error. Free the returned object with Glib::object_unref().
Exceptions
Glib::Error
Glib::RefPtr<const SocketAddress> Gio::SocketConnection::get_remote_address ( ) const

Try to get the remote address of a socket connection.

Since GLib 2.40, when used with g_socket_client_connect() or g_socket_client_connect_async(), during emission of Gio::SocketClientEvent::CONNECTING, this function will return the remote address that will be used for the connection. This allows applications to print e.g. "Connecting to example.com (10.42.77.3)...".

Since glibmm 2.22:
Returns
A SocketAddress or nullptr on error. Free the returned object with Glib::object_unref().

Glib::Error
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 Socket or nullptr 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:

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 ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gio::SocketConnection::is_connected ( ) const

Checks if connection is connected.

This is equivalent to calling g_socket_is_connected() on connection's underlying Socket.

Since glibmm 2.32:
Returns
Whether connection is connected.
SocketConnection& Gio::SocketConnection::operator= ( SocketConnection&&  src)
noexcept
Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Socket> > Gio::SocketConnection::property_socket ( ) const

The underlying GSocket.

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