## Detailed Description

### template<typename T, typename Mutex>
class boost::threadpool::detail::locking_ptr< T, Mutex >

Smart pointer with a scoped locking mechanism.

This class is a wrapper for a volatile pointer. It enables synchronized access to the internal pointer by locking the passed mutex.

Definition at line 37 of file locking_ptr.hpp.
