I don't know about others but I find that wording ambiguous. Like it's saying that once you've done that it can't fail. I think I'd prefer something like: errno = 0; /* Make error condition detectable */ or even errno = 0; /* clear pending errors */ or errno = 0; /* clear prior detected errors */ YMMV, -- Martijn van Oosterhout <kleptog@svana.org> http://svana.org/kleptog/ > Patent. n.
