## Detailed Description

A TCP SocketConnection.

This is the subclass of SocketConnection that is created for TCP/IP sockets.

Since glibmm 2.24:

## Constructor & Destructor Documentation

## TcpConnection()

Gio::TcpConnection::TcpConnection | ( | TcpConnection&& | src | ) |

noexcept

## ~TcpConnection()

Gio::TcpConnection::~TcpConnection | ( |  | ) |

override noexcept

## Member Function Documentation

## get_graceful_disconnect()

bool Gio::TcpConnection::get_graceful_disconnect | ( |  | ) | const

Checks if graceful disconnects are used.

See g_tcp_connection_set_graceful_disconnect().

Since glibmm 2.22:

Returns
  `true` if graceful disconnect is used on close, `false` otherwise.

## get_type()

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

static

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

## gobj() [1/2]

GTcpConnection* Gio::TcpConnection::gobj | ( |  | ) |

inline

Provides access to the underlying C GObject.

## gobj() [2/2]

const GTcpConnection* Gio::TcpConnection::gobj | ( |  | ) | const

inline

Provides access to the underlying C GObject.

## gobj_copy()

GTcpConnection* Gio::TcpConnection::gobj_copy | ( |  | ) |

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

## operator=()

TcpConnection& Gio::TcpConnection::operator= | ( | TcpConnection&& | src | ) |

noexcept

## property_graceful_disconnect() [1/2]

Glib::PropertyProxy< bool > Gio::TcpConnection::property_graceful_disconnect | ( |  | ) |

Whether or not close does a graceful disconnect.

Default value: `false`

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

## property_graceful_disconnect() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gio::TcpConnection::property_graceful_disconnect | ( |  | ) | const

Whether or not close does a graceful disconnect.

Default value: `false`

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

## set_graceful_disconnect()

void Gio::TcpConnection::set_graceful_disconnect | ( | bool | graceful_disconnect | ) |

This enables graceful disconnects on close.

A graceful disconnect means that we signal the receiving end that the connection is terminated and wait for it to close the connection before closing the connection.

A graceful disconnect means that we can be sure that we successfully sent all the outstanding data to the other end, or get an error reported. However, it also means we have to wait for all the data to reach the other side and for it to acknowledge this by closing the socket, which may take a while. For this reason it is disabled by default.

Since glibmm 2.22:

Parameters

  graceful_disconnect | Whether to do graceful disconnects or not.

## Friends And Related Function Documentation

## wrap()

Glib::RefPtr< Gio::TcpConnection > wrap | ( | GTcpConnection * | object,
|  | bool | take_copy = `false`
| ) |  |

related

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.
