Since POSIX references the C standard for this, there isn't an
inconsistency. I can't tell if you're confused or not. :-)

In preference to this book, I recommend using the "Single Unix

(This isn't the only error I have found in the O'Reilly POSIX book,
but since I haven't used it much (I now have the real standards) I
don't really know if I've found the only errors, or if it is just
inaccurate. Maybe there is an errata page at www.oreilly.com?)
