Function template get_parent_from_member



// In header: <boost/intrusive/parent_from_member.hpp>

template<typename Parent, typename Member> 
  const Parent * 
  get_parent_from_member(const Member * member, 
                         const Member Parent::* ptr_to_member);


Given a const pointer to a member and its corresponding const pointer to data member, this function returns the const pointer of the parent containing that member. Note: this function does not work with pointer to members that rely on virtual inheritance.
