Defined in header <mutex>
template< class Mutex > class shared_lock;		(since C++14)

The class shared_lock is a general-purpose shared mutex ownership wrapper allowing deferred locking, timed locking and transfer of lock ownership,

The shared_lock class is movable, but not copyable -- it meets the requirements of MoveConstructible and MoveAssignable but not of CopyConstructible or CopyAssignable.

Template parameters

Mutex

-

the type of the shared mutex to lock. The type must meet the SharedMutex requirements
