Name

pointer_to_unary_function class template — Functional for a pointer to a unary function

Synopsis

template <typename Arg, typename Rtn>
class pointer_to_unary_function :
  public unary_function<Arg, Rtn>
{
public:
  explicit pointer_to_unary_function(Result (*f)(Arg));
  Rtn operator(  )(Arg x) const;
};

The pointer_to_unary_function class template is a function object that wraps a pointer to a function, in which the function is an ordinary (nonmember) function that takes one argument. The ptr_fun function template is the most convenient way to create a pointer_to_unary_function object.
