he WriterGuard is used to remove volatileness and simultaneously gain access to the entire interface of the shared object. It performs exclusive locking of the mutex exposed by the shared object.

The following is the public interface of the WriterGuard.

template <class X,class Mutex>

class WriterGuard



explicit WriterGuard( volatile X& x );

explicit WriterGuard( volatile X* x );

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

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


Mutex& mutex() const;

X* operator->();

X& operator*();

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.
