+ * @class ACE_OS_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 invoke() on this object.  Therefore,
+ * the invoke() method is responsible for deleting itself.
