he ReaderGuard is used to remove volatileness and simultaneously gain access to the const-part of the shared object's interface. It performs shared (reader) locking of the mutex exposed by the shared object.

The following is the public interface of the ReaderGuard.

template <class X,class Mutex>

class ReaderGuard



explicit ReaderGuard( volatile const X& x );

explicit ReaderGuard( volatile const X* x );

ReaderGuard( volatile const X& x, volatile const Mutex& mutex );

ReaderGuard( volatile const X* x, volatile const Mutex& mutex );


Mutex& mutex() const;

const X* operator->() const;

const X& operator*() const;

const X* ptr() const;


All constructors throw boost::thread_resource_error. All other functions do not throw.

See the section ( Preventing race condition section ) for an example.
