Also could we add an entry ENOERROR in sys/errno.h as an extension and for consistency. The ENOERROR value is mentioned in the code-base at least twice. #define ENOERROR 0 /* No error */ AFAIR Tru64 defines for 0 symbol EOK. I discovered lack of EOK equivalent symbol while porting AdvFS. I used there "0". -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJW89akAAoJEEuzCOmwLnZsfgoP/2j3v0QOd7zYj8Um7yVv4WE9 fbT50lOI4gmO3B1BlFDTaIbqOCST4vLfYUD/S1sWYRfUMKUlS9JZBcaK0P2iiL1Q GURh1lFuqebrHxuag2ATMbY80T8QJsZMDRfuAnvoU9fW1kob5fA2PaVc1cBfvV9M YxRGHI/Kgoz6X/rwYvWe7EypT6UshfifGAlRdLobQS5dCZVlJ0ceVLoV3gWzE6Zt zfIhNkl8khaFucunIe0yB0KypgZejDS+f8q1mS87onF9l0063ZtkC6WHdA1I7jLy tnSSYZt2HZSc8AchxBqHJbe6B8/nFLkfk/P1SKmlOaNBMS5neKrmyLFSMZskX2KQ QxY6VRqIJCmT+u742RNvlv377Yen1fFv95hcLKUV6hQDVaxbDgpwb2SFpVQY3Hw+ hy15zpmIsZ420iMfkLW4krpGrU6BpZKXuO29T5N2IKNj3pP3TmRmNyn0MYXWQvbj a9EYZ8OIz3ZCwcAzPJkqRpn3+n/dI92ztUbCjPTGQJ4vviE/fXoPrmGgG4aBaNwF rF9ihlCxq5QtCFIM2/VJu61FOjx3o7DKK0jHSuJDpLAN53sq+iRcYa+3KlMSJUEm O6vx9oOP9W7cvpdLJXdXWOX2KTsI3H3kD4QGItAomZ37zvcLxnYYrWdZPAiJ+EU9 GfIEpzCMCNDxeit7X1kj =kJMn -----END PGP SIGNATURE-----
