Yeah, I missed where this was shown in the email. As far as the link for Drerk's web page is concerned, I suspect it is a reference to the first ed of his book.
>From what I gathered, syscall is not POSIX compliant and could cause compatibility issues so it's use is discouraged. This I would suspect is why there are suggestions from the error when running the example to use 'swscanf' and 'getpt' instead. However, as you found, 'syscall' is defined in 'unistd.h' so having this included is required which does not seem that new. Then again, the code on Derek's site is at least 6 years old and may not be kept up to date which could explain the use of syscall there.
