Beispiele

Im folgenden Codebeispiel wird eine instance der Editor-Anwendung gestartet. Im Beispiel werden dann verschiedene Eigenschaften des zugeordneten Prozesses abgerufen und angezeigt. Das Beispiel erkennt, wann der Prozess beendet wird, und zeigt den Exitcode und die Spitzenspeicherstatistik an.

Hinweise

Der von dieser Eigenschaft zurückgegebene Wert stellt die maximale Größe des virtuellen Arbeitsspeichers dar, die der Prozess seit dem Start in Bytes verwendet hat. Das Betriebssystem ordnet den virtuellen Adressraum für jeden Prozess entweder Seiten zu, die in den physischen Arbeitsspeicher geladen wurden, oder Seiten, die in der Auslagerungsdatei des virtuellen Speichers auf dem Datenträger gespeichert sind.

Diese Eigenschaft kann verwendet werden, um die Arbeitsspeicherauslastung auf Computern mit 32-Bit- oder 64-Bit-Prozessoren zu überwachen. Der Eigenschaftswert entspricht dem Leistungsindikator Für virtuelle Bytes Peak für den Prozess.
