.. class:: IPv6TclassMessage(**properties: ~typing.Any)
   :no-contents-entry:


Superclasses: :class:`~gi.repository.Gio.SocketControlMessage`, :class:`~gi.repository.GObject.Object`





Contains the Traffic Class byte of an IPv6 header.

This consists of the DSCP field as per
`RFC 2474 <https://www.rfc-editor.org/rfc/rfc2474#section-3>`__\,
and the ECN field as per
`RFC 3168 <https://www.rfc-editor.org/rfc/rfc3168#section-5>`__\.

It may be received using :obj:`~gi.repository.Gio.Socket.receive_message` over UDP sockets
(i.e. sockets in the ``G_SOCKET_FAMILY_IPV6`` family with
``G_SOCKET_TYPE_DATAGRAM`` type). The message is not meant for sending. To set
Traffic Class field to be used in datagrams sent on a :obj:`~gi.repository.Gio.Socket` use:


.. code-block:: c
    :dedent:

    g_socket_set_option (socket, IPPROTO_IPV6, IPV6_TCLASS, <TC value>, &error);
