DBusConnection.sendMessage
bool sendMessage(gio.dbus_message.DBusMessage message, gio.types.DBusSendMessageFlags flags, out uint outSerial)Asynchronously sends message to the peer represented by connection.
Unless flags contain the [gio.types.DBusSendMessageFlags.PreserveSerial] flag, the serial number will be assigned by connection and set on message via [gio.dbus_message.DBusMessage.setSerial]. 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. While it has a volatile qualifier, this is a historical artifact and the argument passed to it should not be volatile.
If connection is closed then the operation will fail with [gio.types.IOErrorEnum.Closed]. If message is not well-formed, the operation fails with [gio.types.IOErrorEnum.InvalidArgument].
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 [gio.types.DBusSendMessageFlags.PreserveSerial] flag.
