 NAME

   pointer_to_unary_function  - A function object class that adapts a
   pointer to a function	to work	where a	unary_function is called for.

 SYNOPSIS

   #include <functional>

   template <class Arg, class Result>
   class	pointer_to_unary_function : public unary_function<Arg, Result>;

 DESCRIPTION

   The pointer_to_unary_function	class encapsulates a pointer to	a
   single-argument function.  The class	provides an operator() so that
   the  resulting object serves	as a function object for that
   function.

   The ptr_fun function is overloaded to	create instances of
   pointer_to_unary_function when provided with the appropriate pointer
   to a function.

 INTERFACE

   template <class Arg, class Result>
   class	pointer_to_unary_function : public unary_function<Arg, Result> {

   public:
     typedef typename unary_function<Arg,Result>::argument_type
 						 argument_type;
     typedef typename unary_function<Arg,Result>::result_type
 						 result_type;
     explicit pointer_to_unary_function (Result (*f)(Arg));
     Result operator() (const Arg&) const;
   };

   template<class Arg, class Result>
   pointer_to_unary_function<Arg, Result>
    ptr_fun (Result (*f)(Arg));
