pointer_to_binary_function binary_function
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.
namespace std { template <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; }; }
