constexpr mutex() noexcept;
(1) (since C++11)
mutex( const mutex& ) = delete;
(2) (since C++11)
1) Constructs the mutex. The mutex is in unlocked state after the constructor completes.
2) Copy constructor is deleted.

Parameters

(none)

Notes

Because the default constructor is constexpr, static mutexes are initialized as part of static non-local initialization, before any dynamic non-local initialization begins. This makes it safe to lock a mutex in a constructor of any static object.
