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 and 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.
Parameters
message | a #GDBusMessage |
flags | flags affecting how the message is sent |
outSerial | return location for serial number assigned to message when sending it or null |
Returns
true if the message was well-formed and queued for
