At the top of your program:

puOneShot *backButton = NULL ;

...then somewhere *AFTER* puInit() but *BEFORE* you go into your main
processing loop:

   backButton = new puOneShot ( ...whatever... ) ;

If you are feeling cautious, then in your callback, you can put:

   assert ( backButton != NULL ) ;
