Constructs a new atomic_weak_ptr object.

1) The default constructor initializes the object to an empty state.

2) Initializes the underlying weak_ptr<T> with desired. The initialization is not atomic.

3) Atomic variables are not CopyConstructible.

Parameters

desired

-

value to initialize with
