That works with a different object though. Make sure that you don't mix
them:

type CTextHelper is new System.Address;
type CKeyboardHelper is new System.Address;

function CreateKeyboardHelper
  (name : access Interfaces.C.Char_Array) return CKeyboardHelper;
procedure CKHSendString
 (helper : CKeyboardHelper; string : in out Interfaces.C.Char_Array);
...

And I would really try to find some documentation on the DLL. If "in out"
solved the problem, and they indeed change the string contents, you better
know how exactly.
