Si plusieurs threads d'exécution accéder à l'objet référencé par le std::shared_ptr même sans synchronisation, une race de données peut se produire, à moins que tous les accès se fait par le biais de ces fonctions, qui sont des spécialisations partielles des fonctions correspondantes accès atomiques (std::atomic_load, std::atomic_store, etc.)
Original:
If multiple threads of execution access the object referenced by the same std::shared_ptr without synchronization, a data race may occur, unless all such access is performed through these functions, which are partial specializations of the corresponding atomic access functions (std::atomic_load, std::atomic_store, etc)
