smproxy - Session Manager Proxy
smproxy [-clientId id] [-restore saveFile] [-version]
-clientId id Specifies the session ID used by smproxy in the previous session. -restore saveFile Specifies the file used by smproxy to save state in the previous session. -version Prints the program version and exits.
smproxy allows X applications that do not support X11R6 session management to participate in an X11R6 session. In order for smproxy to act as a proxy for an X application, one of the following must be true: - The application maps a top level window containing the WM_CLIENT_LEADER property. This property provides a pointer to the client leader window which contains the WM_CLASS, WM_NAME, WM_COMMAND, and WM_CLIENT_MACHINE properties. or ... - The application maps a top level window which does not contain the WM_CLIENT_LEADER property. However, this top level window contains the WM_CLASS, WM_NAME, WM_COMMAND, and WM_CLIENT_MACHINE properties. An application that support the WM_SAVE_YOURSELF protocol will receive a WM_SAVE_YOURSELF client message each time the session manager issues a checkpoint or shutdown. This allows the application to save state. If an application does not support the WM_SAVE_YOURSELF protocol, then the proxy will provide enough information to the session manager to restart the application (using WM_COMMAND), but no state will be restored.
