This is not good. This will just encourge more programers to not properly test return values. Read man 2 errno says: "Successful calls never set errno;", so this depends upon the programmer initalizing errno to 0 before they make their call. If they are already so poor as to be calling perror, etc with errno 0, then I doubt that we can depend upon them initalizing errno to 0 and giving consistant results. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not." _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
