I suggest that you allocate the bigger buffer first, then copy the string, then set the last char to "X".
And it's definitely not doing what you described (but for some reason I quoted DaveD's post rahter than the original poster):Your code adds one to the LENGTH of the string, and appends an "X" on the end of the string - or at least it looks like that's what you were trying to do, but did things a little bit wrong order - I can't see how that is of any use to anyone (not that adding/subtracting one from each character is particularly useful either, unless you are using it for very basic encryption).I have to have it. The ++ operators are supposed to add one to each character in the string literal pointed at by buf. The --operators subtract one from each character.
Does anybody seen any errors or have any other suggestions?
