Défini dans l'entête <atomic>
#define ATOMIC_VAR_INIT(value) /* implementation-defined */

Développe l'expression d'un qui peut être utilisé pour initialiser un objet std::atomic qui peut être initialisée à partir value. Si l'objet a une durée de stockage atomique statique, cette initialisation est initialisation constante .

Original:

Expands the an expression which can be used to initialize an std::atomic object that can be initialized from value. If the atomic object has static storage duration, this initialization is initialisation constante.

Notes

Accès à la variable lors de l'initialisation à partir d'un autre thread, même à travers une opération atomique, est une course de données (il peut arriver si l'adresse est immédiatement transmis à un autre thread avec une opération std::memory_order_relaxed)

Original:

Accessing the variable during initialization from another thread, even through an atomic operation, is a data race (it may happen if the address is immediately passed to another thread with a std::memory_order_relaxed operation)

Cette macro est principalement fournie pour la compatibilité avec C, il se comporte comme le constructeur de std::atomic .

Original:

This macro is primarily provided for compatibility with C; it behaves the same as the constructor of std::atomic.
