Daemon (Service) Daemon oder Windows System Service Daemon oder auch Service Routinen sind mit Free Pascal siehe wiki.freepascal.org/Daemons_and_Services("https://wiki.freepascal.org/Daemons_and_Services") leicht zu realisieren, hier ein kleines Beispiel inklusive EventLog-Ausgabe. Eine Variante in der FreeOnTerminate des Threads auf true gesetzt ist, wodurch im Daemon.Stop einfach mit Terminate das beenden des Threads eingeleitet werden kann und mit WaitFor auf das Ende gewartet werden kann. thedaemon.lpr("https://www.gocher.me/code/thedaemon.lpr") Ausgabe: > thedaemon.exe --install thedaemon [2016-12-01 19:31:02.891 Debug] DaemonMapper.Create thedaemon [2016-12-01 19:31:02.891 Debug] DaemonMapper.Createted thedaemon [2016-12-01 19:31:02.891 Debug] DaemonMapper.Install thedaemon [2016-12-01 19:31:02.907 Debug] Daemon.installed: true > net start theDaemon thedaemon [2016-12-01 19:31:05.360 Debug] DaemonMapper.Create thedaemon [2016-12-01 19:31:05.360 Debug] DaemonMapper.Createted thedaemon [2016-12-01 19:31:05.360 Debug] DaemonMapper.Run thedaemon [2016-12-01 19:31:05.360 Info] Daemon TheDaemon current status: Start Pending thedaemon [2016-12-01 19:31:05.360 Debug] Daemon.Start: true thedaemon [2016-12-01 19:31:05.360 Info] Daemon TheDaemon current status: Running thedaemon [2016-12-01 19:31:05.360 Debug] Daemon.Execute: false thedaemon [2016-12-01 19:31:05.360 Debug] Thread.Execute thedaemon [2016-12-01 19:31:06.376 Debug] Thread.Loop Tick :1 thedaemon [2016-12-01 19:31:07.379 Debug] Thread.Loop Tick :2 thedaemon [2016-12-01 19:31:08.382 Debug] Thread.Loop Tick :3 > net pause theDaemon thedaemon [2016-12-01 19:31:08.820 Info] Daemon TheDaemon current status: Pause Pending thedaemon [2016-12-01 19:31:08.820 Debug] Daemon.Pause: true thedaemon [2016-12-01 19:31:08.820 Info] Daemon TheDaemon current status: Paused > net continue theDaemon thedaemon [2016-12-01 19:31:12.655 Info] Daemon TheDaemon current status: Continue Pending thedaemon [2016-12-01 19:31:12.655 Debug] Daemon.Continue: true theDaemon [2016-12-01 19:31:12.655 Info] Daemon TheDaemon current status: Running theDaemon [2016-12-01 19:31:13.224 Debug] Thread.Loop Tick :4 theDaemon [2016-12-01 19:31:14.239 Debug] Thread.Loop Tick :5 theDaemon [2016-12-01 19:31:15.255 Debug] Thread.Loop Tick :6 theDaemon [2016-12-01 19:31:16.256 Debug] Thread.Loop Tick :7 > net stop theDaemon theDaemon [2016-12-01 19:31:16.725 Info] Daemon TheDaemon current status: Stop Pending theDaemon [2016-12-01 19:31:16.725 Debug] Daemon.Stop: true thedaemon [2016-12-01 19:31:17.272 Debug] Thread.Loop Tick :8 thedaemon [2016-12-01 19:31:17.272 Debug] Thread.LoopStopped thedaemon [2016-12-01 19:31:17.272 Debug] Thread.Destroy theDaemon [2016-12-01 19:31:17.272 Info] Daemon TheDaemon current status: Stopped > thedaemon.exe --uninstall theDaemon [2016-12-01 19:31:20.198 Debug] DaemonMapper.Create theDaemon [2016-12-01 19:31:20.198 Debug] DeamonMapper.Createted theDaemon [2016-12-01 19:31:20.214 Debug] DeamonMapper.Uninstall theDaemon [2016-12-01 19:31:20.214 Debug] Daemon.Uninstall: true
