DBusConnection.sendMessage

Asynchronously sends @message to the peer represented by @connection.

Unless @flags contain the %G_DBUS_SEND_MESSAGE_FLAGS_PRESERVE_SERIAL flag, the serial number will be assigned by @connection and set on @message via g_dbus_message_set_serial(). If @out_serial is not %NULL, then the serial number used will be written to this location prior to submitting the message to the underlying transport.

If @connection is closed then the operation will fail with %G_IO_ERROR_CLOSED. If @message is not well-formed, the operation fails with %G_IO_ERROR_INVALID_ARGUMENT.

See this server[gdbus-server] and client[gdbus-unix-fd-client] for an example of how to use this low-level API to send and receive UNIX file descriptors.

Note that @message must be unlocked, unless @flags contain the %G_DBUS_SEND_MESSAGE_FLAGS_PRESERVE_SERIAL flag.
