Constants
atomic_ref::is_always_lock_free
static constexpr bool is_always_lock_free = /*implementation-defined*/ ;
(seit C++20)

Gleich true wenn Operationen auf diesem atomic_ref Typ immer lock-free sind und false wenn sie niemals oder manchmal lock-free sind.

Der Wert dieser Konstanten stimmt mit dem Ergebnis der Memberfunktion is_lock_free überein.
