std::atomic<T>::operator=: std::atomic<T>::operator=

NAME

std::atomic<T>::operator= - std::atomic<T>::operator=

Synopsis

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

1) Atomically assigns a value desired to the atomic variable. Equivalent to store(desired).
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.
