(3) (since C++11)

Constructs new atomic variable.

1) The default constructor is trivial: no initialization takes place other than zero initialization of static and thread-local objects. std::atomic_init may be used to complete initialization.
2) Initializes the underlying value with desired. The initialization is not atomic.
3) Atomic variables are not CopyConstructible.

desired - value to initialize with
