* @class ACE_Thread_Adapter
*
* @brief Converts a C++ function into a function that
* can be called from a thread creation routine
* (e.g., pthread_create() or _beginthreadex()) that expects an
* extern "C" entry point. This class also makes it possible to
* transparently provide hooks to register a thread with an
* ACE_Thread_Manager.
*
* This class is used in ACE_OS::thr_create(). In general, the
* thread that creates an object of this class is different from
* the thread that calls @c invoke() on this object. Therefore,
* the @c invoke() method is responsible for deleting itself.
