std::experimental::atomic_weak_ptr<T>::operator= (3) - Linux Manuals

std::experimental::atomic_weak_ptr<T>::operator=: std::experimental::atomic_weak_ptr<T>::operator=

NAME

std::experimental::atomic_weak_ptr<T>::operator= - std::experimental::atomic_weak_ptr<T>::operator=

Synopsis


void operator=( weak_ptr<T> desired ) noexcept; (1)
void operator=( const atomic_weak_ptr& ) = delete; (2)


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

Notes


Unlike most assignment operators, the assignment operators for atomic_weak_ptr returns void.


Remarks


All changes to the atomic_weak_ptr object itself, and all associated use_count increments, are guaranteed to be performed atomically. Associated use_count decrements take place after the atomic operation, but are not required to be part of it. Any associated destruction or deallocation operations take place after the atomic operation and are not part of it.
