En outre, std::atomic_flag peut être initialisé à la valeur d'état clair à l'ATOMIC_FLAG_INIT expression. Pour une atomic_flag avec la durée de stockage statique, ce qui garantit que les valeurs de cet indicateur est connu avant tout les constructeurs sont gérés pour les objets statiques .
Original:
In addition, std::atomic_flag can be value-initialized to clear state with the expression ATOMIC_FLAG_INIT. For an atomic_flag with static storage duration, this guarantees that the values of this flag is known before any constructors are run for static objects.
