operator weak_ptr<T>() const;

Atomically loads and returns the current value of the atomic_weak_ptr. Equivalent to load().

Parameters

(none)

Return value

The current value of the atomic_weak_ptr.

Remarks

All associated use_count increments are guaranteed to be performed as part of the atomic operation.

Exceptions
