std::atomic::atomic

atomic() = default;	(1)	(since C++11)
constexpr atomic( T desired );	(2)	(since C++11)
atomic( const atomic& ) = delete;	(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.

Parameters

desired

value to initialize with

Exceptions
