using [method@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 [class@Gio.Socket] use: c g_socket_set_option (socket, IPPROTO_IPV6, IPV6_TCLASS, <TC value>, &error);
IPv6TclassMessage (Handle = null)
Creates a new
IPv6TclassMessageby wrapping a native handle or another wrapper.
Handle is the native handle or another wrapper whose handle to adopt.toNativeHandle (Source)
Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from
fn.call(...), another generated wrapper exposinghandle(), or null. Returns null when the argument carries no pointer.
Source is the raw handle, raw buffer, wrapper, or null.A raw pointer carrier or null when no pointer is present.getLib ()
Returns the opened native library for this generated wrapper.
The opened native library.handle ()
Returns the wrapped NativeHandle.
The wrapped NativeHandle.isNull ()
Returns true when the wrapped handle is null.
A bool.describe ()
Returns a small string for debugging generated wrappers.
A string.asSocketControlMessage ()
Wraps this handle as
SocketControlMessage.
A SocketControlMessage object.get_ecn ()
Gets the Explicit Congestion Notification code point stored in @message.
