unique_lock Class
Represents a template that can be instantiated to create objects that manage the locking and unlocking of a mutex.
template<class Mutex>
class unique_lock;
Remarks
The template argument Mutex must name a mutex type.
Internally, a unique_lock stores a pointer to an associated mutex object and a bool that indicates whether the current thread owns the mutex.
