Detailed Description

   template<typename _StateT>
       class std::fpos< _StateT >"Class representing stream positions.

       The standard places no requirements upon the template parameter StateT. In this
       implementation StateT must be DefaultConstructible, CopyConstructible and Assignable. The
       standard only requires that fpos should contain a member of type StateT. In this
       implementation it also contains an offset stored as a signed integer.

       Parameters
           StateT Type passed to and returned from state().
