template< class Arg, class Result >class pointer_to_unary_function:publicstd::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.

[edit]Member functions

(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 apointer_to_unary_function function object with the stored functionf.

Parameters

pointer to a function to store

std::pointer_to_unary_function::operator()

Result operator()( Arg x)const;

Calls the stored function.

Parameters

argument to pass to the function

Return value

The value returned by the called function.
