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,
