Définition d’opérations en C++

Dans le Gestionnaire d’autorisation, une opération est une fonction ou une méthode de bas niveau d’une application. Ces opérations sont regroupées sous forme de tâches. Les utilisateurs de l’application demandent l’autorisation d’effectuer des tâches. Une opération est représentée par un objet IAzOperation . Pour plus d’informations sur les opérations, consultez Opérations et tâches.

L’exemple suivant montre comment définir des opérations dans un magasin de stratégies d’autorisation. L’exemple suppose qu’il existe un magasin de stratégies XML nommé MyStore.xml dans le répertoire racine du lecteur C et que ce magasin contient une application nommée Expense.
