Beispiel

Im folgenden Beispiel wird eine Instanz von Editor gestartet. Anschließend wird die Auslastung des physikalischen Speichers durch den zugeordneten Prozess in Intervallen von zwei Sekunden für maximal zehn Sekunden abgerufen. Dabei wird ermittelt, ob der Prozess vor Ablauf von zehn Sekunden beendet wird. Im Beispiel wird der Prozess beendet, wenn er nach zehn Sekunden weiterhin ausgeführt wird.
