Or if you don't want to dynamically allocate t:

  T t;
  f( boost::dumb_ptr< T >( &t ) ); // clearly an in/out parameter

  static T t;
  f( boost::dumb_ptr< T >( &t ) ); // clearly an in/out parameter

  boost::dumb_ptr< T > t = f(); // must be an out parameter whose memory
is managed by f()

  T t = *f().get(); // must be an out parameter whose memory is managed
by f()

  T &t = *f(); // must be an out parameter whose memory is managed by
f()
