NAMEpointer_to_binary_function
- A function object that adapts a pointer to a binary function, to
take the place of a binary_function.
SYNOPSIS
#include <functional>
template <class Arg1, class Arg2, class Result>
class pointer_to_binary_function : public
binary_function<Arg1, Arg2, Result> ;
DESCRIPTION
The pointer_to_binary_function class encapsulates a pointer to a two-
argument function. The class uses operator() so that the resulting
object serves as a binary function object for that function.
The ptr_fun function is overloaded to create instances of a
pointer_to_binary_function when included with the appropriate pointer
to a function.
INTERFACEtemplate <;class Arg1, class Arg2, class Result>
class pointer_to_binary_function : public
binary_function<Arg1, Arg2, Result> {
public:
explicit pointer_to_binary_function
(Result (*f)(Arg1, Arg2));
Result operator() (const Arg1&, const Arg2&) const;
};
template<;class Arg1, class Arg2, class Result>
pointer_to_binary_function<;Arg1, Arg2, Result>
ptr_fun (Result (*x)(Arg1, Arg2));
