template< class Arg, class Result > class pointer_to_unary_function : public std::unary_function<Arg, Result>;		(deprecated)

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

f

-

pointer to a function to store

std::pointer_to_unary_function::operator()

Result operator()( Arg x ) const;

Calls the stored function.

x

-

argument to pass to the function

The value returned by the called function.

pointer_to_binary_function (deprecated)	adaptor-compatible wrapper for a pointer to binary function (class template)
ptr_fun (deprecated)	creates an adaptor-compatible function object wrapper from a pointer to function (function template)
