Is there any analog of the void type used in C/C++? 1

Hi, fellows!

Could you tell me, please, is there any analogue in Delphi of the void type used in C/C++? I would like to use a value of the void type (as comprehended in C/C++) as parameter of a procedure/function. How to implement this in Delphi, if possible?

I understand that the Pointer type is the equivalent of the C++ void* type.

Here is an example of its use:

procedure subroutine( p: pointer );
var
  z: integer;
begin
  z := integer(p^);
  ShowMessage ( IntToStr(z) );
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  x: integer;
  p: pointer;
begin
  x := 21;
  p := addr(x);
  subroutine( p );
end;
