NAME

     iosfwd

      - The  header  iosfwd  forward  declares  the  input/output
     library  template  classes and specializes them for wide and
     tiny characters. It also defines the positional  types  used
     in  class  char_traits instantiated on tiny and wide charac-
     ters.

SYNOPSIS

     #include <iosfwd>
     // forward declare the traits class
     template<class charT> struct char_traits;

     // forward declare the positioning class
     template<class stateT> class fpos;

     // forward declare the state class
     class mbstate_t;

     // forward declare the allocator class
     template<class T> class allocator;

     // forward declare the iostreams template classes
     template<class charT,class traits=char_traits<charT>>
