std::mutex::mutex

constexpr mutex();
 (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).

Exceptions

noexcept specification:
noexcept

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.
