+ * @class ACE_OS_Thread_Adapter
+ *
+ * @brief Converts a C++ function into a function <ace_thread_adapter>
+ * 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.
