NAME
     basic_iostream

      - Assists in formatting and interpreting sequences of char-
     acters controlled by a stream buffer.



SYNOPSIS
     #include <istream>
     template<class charT, class traits = char_traits<charT> >
     class basic_iostream
     : public basic_istream<charT, traits>,
     public basic_ostream<charT, traits>



DESCRIPTION
     The class basic_iostream inherits a number of functions from
     classes           basic_ostream<charT,_traits>           and
     basic_istream<charT,_traits>. They assist in formatting  and
     interpreting  sequences of characters controlled by a stream
     buffer. Two groups of functions share common properties, the
     formatted functions and the unformatted functions.



INTERFACE
     template<class charT, class traits>
     class basic_iostream
     : public basic_istream<charT, traits>,
      public basic_ostream<charT, traits>

     {

     public:

      explicit basic_iostream(basic_streambuf<charT, traits>
                             *sb);
      virtual ~basic_iostream();
     };



PUBLIC CONSTRUCTORS
     explicit basic_iostream(basic_streambuf<charT, traits>
                             *sb);


        Constructs an object of class  basic_iostream,  assigning
        initial   values   to   the   base   class   by   calling
        basic_istream<charT, traits>(sb) and basic_ostream<charT,
        traits>(sb).



DESTRUCTORS
     virtual ~basic_iostream();


        Destroys an object of class basic_iostream.
