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.
