Function template get_parent_from_member



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

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


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