Hey, special thanks for your detailed explanation. Now its clear for me! But now i have a new problem! I pass the generated char** to a dynamic list.
temp1 = ConvertBestellungenList (); size = sizeof (temp1); LstSetListChoices (theListPtr, temp1, size); Sometimes it works fine, sometimes i get an "invalid chunk ptr". I am not sure whats going wrong. I debugged this, and before the call of LstSetListChoices, im looked in the temp1-char** It looks like that all is correct, but the error still occur!
