NAME

std::atomic_ref::required_alignment - std::atomic_ref::required_alignment

Synopsis

static constexpr std::size_t required_alignment= (since C++20)
/*implementation-defined*/;

The value of required_alignment is the required alignment for an object to be
referenced by an atomic reference, which is at least alignof(T).

Notes

Hardware could require that an object to be referenced by an atomic_ref<T> have
stricter alignment than other T objects, and whether operations on an atomic_ref are
lock-free can depend on the alignment of the referenced object.
