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.

Si obj n'était pas par défaut construit, le comportement est indéfini .

Original:

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

Si cette fonction est appelée deux fois sur le obj même, le comportement est indéfini .

Original:

If this function is called twice on the same obj, the behavior is undefined.

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.
