They do no such thing. Pointers do not work that way! You cannot "return an address" through a pointer you pass
into a function, any more than you can return a number through a number you pass
into a function.
You do not need to clean up after strerror -- or stat, lstat, or fstat, either.

Hi,
I've noticed that the permissions output from "ls -l" under SunOS differs from Linux in that after the "rwxrwxrwx" field, there is an additional "+" character that may or may not be there. What is the significance of this character?
Thanks,
