The following reply was made to PR docs/48125; it has been noted by GNATS. From: Per Hedeland <per@hedeland.org> To: trhodes@FreeBSD.org Cc: bde@FreeBSD.org, freebsd-doc@FreeBSD.org, FreeBSD-gnats-submit@FreeBSD.org, grog@FreeBSD.org Subject: Re: docs/48125: [PATCH] Incorrect errno strings in intro(2) Date: Mon, 17 Feb 2003 21:40:55 +0100 (CET) Well, I think this issue taking on rather bigger proportions than it really merits, but anyway...

Of course I didn't suggest that code must *never* be changed to match documentation, only that code changes that may actually break things should not be done just to match someone's idea of "good writing style" for the man page. On the other hand, in this particular case the FreeBSD (or *BSD, I don't have another dialect to test) code might actually be a bit out-of-sync with the rest of the Unix family. A survey of two other Unices isn't exactly conclusive, and there's nothing to say that FreeBSD must be like everyone else, but anyway: Solaris 8: $ ./a.out bind: Cannot assign requested address RedHat 7.3: $ ./a.out bind: Cannot assign requested address FreeBSD 5.0-RELEASE: $ ./a.out bind: Can't assign requested address The same difference exists for the other messages that are contractions in the FreeBSD sys_errlist[]. And with that "contribution" I will respectfully leave this discussion, letting the committers sort out what should be changed where and why. --Per To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-doc" in the body of the message
