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 provides an 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 provided with the appropriate pointer to a function.
Interface
template <class Arg1, class Arg2, class Result> class pointer_to_binary_function : public binary_function<Arg1, Arg2, Result> { public: typedef typename binary_function<Arg1, Arg2, Result>::second_argument_type second_argument_type; typedef typename binary_function<Arg1, Arg2, Result>::first_argument_type first_argument_type; typedef typename binary_function<Arg1, Arg2, Result>::result_type result_type; 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));
