Detailed Description

This class allows the creation of a thread context unique 'pointer' that can be set and retrieved and can be used to create thread specific data areas for implementing 'thread safe' library routines.container for thread specific data storage.

Finally, Common C++ supports a thread-safe 'AtomicCounter' class. This can often be used for reference counting without having to protect the counter with a separate Mutex counter. This lends to lighter-weight code.
