 NAME

   iosfwd

 DESCRIPTION

   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 characters.

 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>>
