template < class Arg, class Result > class pointer_to_unary_function : public std:: unary_function < Arg, Result > ;		(deprecated in C++11) (removed in C++17)

std::pointer_to_unary_function is a function object that acts as a wrapper around a unary function.

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

std::pointer_to_unary_function:: pointer_to_unary_function

explicit pointer_to_unary_function ( Result ( * f ) ( Arg ) ) ;

Constructs a pointer_to_unary_function function object with the stored function f .

pointer to a function to store

Result operator ( ) ( Arg x ) const ;

Calls the stored function.

argument to pass to the function

The value returned by the called function.

pointer_to_binary_function (deprecated in C++11) (removed in C++17)	adaptor-compatible wrapper for a pointer to binary function (class template)
ptr_fun (deprecated in C++11) (removed in C++17)	creates an adaptor-compatible function object wrapper from a pointer to function (function template)
