std::atomic_flag::atomic_flag

From cppreference.com
Defined in header <atomic>
atomic_flag();
(1) (since C++11)
atomic_flag( const atomic_flag& ) = delete;
(2) (since C++11)

Constructs a new std::atomic_flag.

1) Trivial default constructor, initializes std::atomic_flag to unspecified state.

2) The copy constructor is deleted; std::atomic_flag is not copyable.

In addition, std::atomic_flag can be value-initialized to clear state with the expression ATOMIC_FLAG_INIT. For an atomic_flag with static storage duration, this guarantees that the values of this flag is known before any constructors are run for static objects.
