| | So where is [b]get_current_dir_name()[/b] defined? Functions must always be declared before they can be used. Since the C compiler does not know any better it will assume the fucntions returns an int, and that is not what the fprintf() statement expects as the parameter. The solution is to prototype it …  |

| | Yes, you need to add more comments -- everywhere. First you need an explaination at the top of the program to tell us what the program is supposed to do. Even "glancing" at main() I don't know what it is trying to do. If in doubt -- comment it. |
