(until C++17)
(deprecated since C++11)

std::pointer_to_binary_function is a function object that acts as a wrapper around a binary function.

(constructor)	constructs a new `pointer_to_binary_function` object with the supplied function (public member function)
operator()	calls the stored function (public member function)

explicit pointer_to_binary_function( Result (*f)(Arg1,Arg2) );

Constructs a pointer_to_binary_function function object with the stored function f.

pointer to a function to store

Result operator()( Arg1 x1, Arg2 x2 ) const;

Calls the stored function.

x1, x2

arguments to pass to the function

The value returned by the called function.

pointer_to_unary_function (until C++17)	adaptor-compatible wrapper for a pointer to unary function (class template)
ptr_fun (until C++17)	creates an adaptor-compatible function object wrapper from a pointer to function (function template)
