std::atomic<T>::operator=

T operator=( T desired ) noexcept;
 (1) (since C++11) 
T operator=( T desired ) volatile noexcept;
 (2) (since C++11) 
atomic& operator=( const atomic& ) = delete;
 (3) (since C++11) 
atomic& operator=( const atomic& ) volatile = delete;
 (4) (since C++11)
1,2) Atomically assigns desired to the atomic variable. Equivalent to store(desired).

It is deprecated if std::atomic<T>::is_always_lock_free is false and overload (2) participates in overload resolution.

 (since C++20)
3,4) Atomic variables are not CopyAssignable.

Parameters

desired - value to assign

Return value

1,2) 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.
