NAME¶

std::atomic::operator= - std::atomic::operator=

Synopsis¶

T operator=( T desired ) noexcept;
T operator=( T desired ) volatile noexcept; (1) (since C++11)
atomic& operator=( const atomic& ) = delete; (1) (since C++11)
atomic& operator=( const atomic& ) volatile = (2) (since C++11)
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.
