void store( weak_ptr<T> desired, std::memory_order order = std::memory_order_seq_cst ) noexcept;

Atomically replaces the current value with desired. Memory is affected according to the value of order.

order must be one of std::memory_order_relaxed, std::memory_order_release or std::memory_order_seq_cst. Otherwise the behavior is undefined.


[edit] Parameters

desired - the weak_ptr to store into the atomic variable
order - memory order constraints to enforce

[edit] Return value


[edit] 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.
