This method initiates a request to restart (ie. reboot) the computer system. This method initiates a request to stop (ie. shutdown) the computer system. The secret cookie that is used to identify the new session This method requests that a new Session be created for the calling process. The properties of this new Session are set automatically from information collected about the calling process. This new session exists until the calling process disconnects from the system bus or calls CloseSession(). It is the responsibility of the calling process to set the environment variable XDG_SESSION_COOKIE to the value of the returned cookie. This cookie should only be made available to child processes of the caller so that they may be identified as members of this session. See this simple example: DBusError error; DBusMessage *message; DBusMessage *reply; message = dbus_message_new_method_call ("org.freedesktop.ConsoleKit", "/org/freedesktop/ConsoleKit/Manager", "org.freedesktop.ConsoleKit.Manager", "OpenSession"); if (message == NULL) { goto out; } dbus_error_init (&error); reply = dbus_connection_send_with_reply_and_block (connector->connection, message, -1, &error); if (reply == NULL) { goto out; } dbus_error_init (&error); if (! dbus_message_get_args (reply, &error, DBUS_TYPE_STRING, &cookie, DBUS_TYPE_INVALID)) { goto out; } OpenSessionWithParameters() An array of sets of property names and values The secret cookie that is used to identify the new session This method requests that a new Session be created for the calling process. The properties of this new Session are from the parameters provided. This new session exists until the calling process disconnects from the system bus or calls CloseSession(). It is the responsibility of the calling process to set the environment variable XDG_SESSION_COOKIE to the value of the returned cookie. This cookie should only be made available to child processes of the caller so that they may be identified as members of this session. See the Session properties for a list of valid parameters. org.freedesktop.ConsoleKit.Session This method is restricted to privileged users by D-Bus policy. The secret cookie that is used to identify the session Whether the session was successfully closed This method is used to close the session identified by the supplied cookie. The session can only be closed by the same process that opened the session. an array of Seat IDs This gets a list of all the Seats that are currently present on the system. Each Seat ID is an D-Bus object path for the object that implements the Seat interface. org.freedesktop.ConsoleKit.Seat an array of Session IDs This gets a list of all the Sessions that are currently present on the system. Each Session ID is an D-Bus object path for the object that implements the Session interface. org.freedesktop.ConsoleKit.Session The secret cookie that is used to identify the session The object identifier for the current session Returns the session ID that is associated with the specified cookie. The POSIX process ID The object identifier for the current session Attempts to determine the session ID for the specified POSIX process ID (pid). The object identifier for the current session Attempts to determine the session ID that the caller belongs to. See this example of using dbus-send: dbus-send --system --dest=org.freedesktop.ConsoleKit \ --type=method_call --print-reply --reply-timeout=2000 \ /org/freedesktop/ConsoleKit/Manager \ org.freedesktop.ConsoleKit.Manager.GetCurrentSession POSIX User identification an array of Session IDs This gets a list of all the Sessions that are currently open for the specified user. Each Session ID is an D-Bus object path for the object that implements the Session interface. User identification an array of Session IDs This gets a list of all the Sessions that are currently open for the specified user. Each Session ID is an D-Bus object path for the object that implements the Session interface. The value of the system-idle-hint Returns TRUE if the idle-hint property of every open session is TRUE or if there are no open sessions. An ISO 8601 format date-type string Returns an ISO 8601 date-time string that corresponds to the time of the last change of the system-idle-hint. The Seat ID for the added seat Emitted when a Seat has been added to the system. The Seat ID for the removed seat Emitted when a Seat has been removed from the system. The value of the system-idle-hint Emitted when the value of the system-idle-hint has changed.
