A session manager keeps track of applications that are 29 running when the desktop shuts down and starts them again in the same 30 state they were left when the desktop starts up the next time. To be able 31 to do this the session manager needs cooperation from applications; 32 applications have to provide sufficient information to be started again as 33 well as restore the state they were left in.

This request is necessary because at any one 44 time only one application can interact with the user. The session manager 45 coordinates these requests and grants every application in need of user 46 interaction a timeslot in which it may interact with the user</li> 47 <li>try to cancel the whole shutdown; the session manager may or may 48 not honor that request.</li> 49 </ul> 50 </li> 51 <li>After saving is done the session manager signals all applications 52 to exit.</li> 53 <li>Applications answer the exit message by disconnecting from the 54 session manager.</li> 55 <li>After all applications have exited or a reasonable timeout the 56 session manager kills all remaining applications and finally lets the 57 desktop shut down.</li> 58 </ol> 59*/ 60service SessionManager 61{ 62 /** XSessionManagerClient (of which there can only be one instance per 63 process) provides an application's interface to the session manager. 64 It keeps track of every listener inside the application and multiplexes 65 the session manager's signals as well as requests to the session manager. 66 */ 67 interface XSessionManagerClient; 68 69}; 70 71}; }; }; }; 72 73#endif 74 75/* vim:set shiftwidth=4 softtabstop=4 expandtab: */ 76
