  // the application.                                                   //
  //									//
  // This retry behaviour can be overridden by installing an exception	//
  // handler.  An exception handler is a function with the same 	//
  // signature as omniORB::transientExceptionHandler_t. The handler 	//
  // will be called when a CORBA::TRANSIENT exception is caught by the 	//
  // ORB. The handler is passed three arguments: a <cookie>, the 	//
  // no. of retries <n_retries> and the value of the exception caught 	//
  // <ex>. The handler is expected to do whatever is appropriate and 	//
  // return a boolean value. If the return value is TRUE (1), the ORB 	//
  // would retry the operation again. If the return value is FALSE (0),	//
  // the CORBA::TRANSIENT exception would be re-throw and is expected   //
  // to be caught by the application code.			      	//
  //									//
  // The overloaded functions omniORB::installTransientExceptionHandler //

  // exception handler for all object references except for those which //
  // have an exception handler installed by the second form, which takes//
  // an addition argument <obj> to identify the target object reference.//
