NAMEpointer_to_unary_function
- A function object class that adapts a pointer to a function, to take
the place of a unary_function.
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 uses 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 included with the appropriate pointer to
a function.
INTERFACE
template <class Arg, class Result>
class pointer_to_unary_function : public
unary_function<Arg, Result> {
public:
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));
