#include <boost/interprocess/offset_ptr.hpp>

 I use boost_1_46_1, 
 boost::interprocess::offset_ptr<int> p; 
    std::cin >> p; // error!!

offset_ptr.hpp

   std::ptrdiff_t get_offset() const
   {  return internal.m_offset;  }

//!operator>> 
//!for offset ptr
template<class E, class T, class Y> 
inline std::basic_istream<E, T> & operator>> 
   (std::basic_istream<E, T> & is, offset_ptr<Y> & p)
{  return is >> p.get_offset();  }
