A function object that adapts a pointer to a binary function, to take the place of a binary_function


#include <functional>

namespace std {
  template <class Arg1, class Arg2, class Result>
  class pointer_to_binary_function;


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.
