Definieren von Vorgängen in C++

Im Autorisierungs-Manager ist ein Vorgang eine Funktion oder Methode auf niedriger Ebene einer Anwendung. Diese Vorgänge werden als Aufgaben gruppiert. Benutzer der Anwendung fordern die Berechtigung zum Ausführen von Aufgaben an. Ein Vorgang wird durch ein IAzOperation-Objekt dargestellt. Weitere Informationen zu Vorgängen finden Sie unter Vorgänge und Aufgaben.

Das folgende Beispiel zeigt, wie Vorgänge in einem Autorisierungsrichtlinienspeicher definiert werden. Im Beispiel wird davon ausgegangen, dass im Stammverzeichnis von Laufwerk C ein XML-Richtlinienspeicher mit dem Namen MyStore.xml vorhanden ist und dieser Speicher eine Anwendung namens Expense enthält.
