smproxy allows X applications that do not support X11R6 session manage-
ment 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.
- 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
