Is it going to contain a pointer to the real data?</div><div>I am probably slightly confused by your comment next to it.</div><div>Could you explain the logic for storing the string data or provide an example of code that handles e.g. the string allocation, or access to it?</div><div>Given that understanding, it should be relatively straightforward to accomplish your task.</div><div><br><div>
