Defined in header <atomic>
template< class T >
void atomic_init( std::atomic<T>* obj, T desired );
template< class T >
void atomic_init( volatile std::atomic<T>* obj, T desired );
Initialise la valeur par défaut construit object objet atomique avec le desired valeur. La fonction n'est pas atomique: l'accès simultané d'un autre thread, même à travers une opération atomique, est une race de données .
Original:
Initializes the default-constructed atomic object object with the value desired. The function is not atomic: concurrent access from another thread, even through an atomic operation, is a data race.

Original:
If obj was not default-constructed, the behavior is undefined.

[modifier] Notes

Cette fonction est fournie pour assurer la compatibilité avec C. Si la compatibilité n'est pas nécessaire, std::atomic peut être initialisé par leurs constructeurs non définis par défaut .
Original:
This function is provided for compatibility with C. If the compatibility is not required, std::atomic may be initialized through their non-default constructors.
