std::atomic<T>::operator=

(1) (since C++11)
T operator=( T desired ) noexcept;
T operator=( T desired ) volatile noexcept;
(since C++11)
(2) (since C++11)
atomic& operator=( const atomic& ) = delete;
atomic& operator=( const atomic& ) volatile = delete;
1) Atomically assigns the desired value to the atomic variable. Equivalent to store(desired). The volatile-qualified version is deprecated if std::atomic<T>::is_always_lock_free is false. (since C++20)
2) Atomic variables are not CopyAssignable.

Parameters

desired - value to assign

Return value

desired.

Notes

Unlike most assignment operators, the assignment operators for atomic types do not return a reference to their left-hand arguments. They return a copy of the stored value instead.
