Mutex
-
the type of the mutex to lock. The type must meet the[BasicLockable
](http://en.cppreference.com/w/cpp/concept/BasicLockable)requirements

Definition
mutex_type
Mutex
Member functions
constructs a lock_guard, optionally locking the given mutex(public member function)
destructs the lock_guard object, unlocks the underlying mutex(public member function)
operator=[deleted]     not copy-assignable(public member function)
