Daemon oder auch Service Routinen sind mit Free Pascal siehe 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.
Ausgabe:
