Note that an empty directory still contains the . Efault In next execution, it throws an error number 17, which is "File already exist". Valid error numbers are all nonzero; errno is never set to zero by any system call or library function.

Inside a C program, when a function fails, you should handle the errors accordingly, or at least record the errors in a log file.
