unpublished service SessionManager
Usage Restrictions

Description
The SessionManager service provides an interface to the session manager of the desktop. A session manager keeps track of applications that are running when the desktop shuts down and starts them again in the same state they were left when the desktop starts up the next time. To be able to do this the session manager needs cooperation from applications; applications have to provide sufficient information to be started again as well as restore the state they were left in. The normal flow of operation looks like this:
  1. The user starts the desktop shutdown.
  2. The session manager informs all its connected applications about the pending shutdown.
  3. Each application saves its current state; while doing this it may
    • The application may request to interact with the user (e.g. to ask where to save documents). This request is necessary because at any one time only one application can iteract with the user. The session manager coordinates these requests and grants every application in need of user interaction a timeslot in which it may interact with the user
    • try to cancel the whole shutdown; the session manager may or may not honor that request.
  4. After saving is done the session manager signals all applications to exit.
  5. Applications answer the exit message by disconnecting from the session manager.
  6. After all applications have exited or a reasonable timeout the session manager kills all remaining applications and finally lets the desktop shut down.
