// 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>.
//
// = DESCRIPTION
// 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.
