  42  *  SYSEXITS.H -- Exit status codes for system programs.
  43  *
  44  *      This include file attempts to categorize possible error
  45  *      exit statuses for system programs, notably delivermail
  46  *      and the Berkeley network.
  47  *
  48  *      Error numbers begin at EX__BASE to reduce the possibility of
  49  *      clashing with other exit statuses that random programs may
  50  *      already return.  The meaning of the codes is approximately
  51  *      as follows:
  52  *
  53  *      EX_USAGE -- The command was used incorrectly, e.g., with
  54  *              the wrong number of arguments, a bad flag, a bad
  55  *              syntax in a parameter, or whatever.
  56  *      EX_DATAERR -- The input data was incorrect in some way.
  57  *              This should only be used for user's data & not
  58  *              system files.
  59  *      EX_NOINPUT -- An input file (not a system file) did not
  60  *              exist or was not readable.  This could also include
  61  *              errors like "No message" to a mailer (if it cared
  62  *              to catch it).
  63  *      EX_NOUSER -- The user specified did not exist.  This might
  64  *              be used for mail addresses or remote logins.
  65  *      EX_NOHOST -- The host specified did not exist.  This is used
  66  *              in mail addresses or network requests.
  67  *      EX_UNAVAILABLE -- A service is unavailable.  This can occur
  68  *              if a support program or file does not exist.  This
  69  *              can also be used as a catchall message when something
  70  *              you wanted to do doesn't work, but you don't know
  71  *              why.
  72  *      EX_SOFTWARE -- An internal software error has been detected.
  73  *              This should be limited to non-operating system related
  74  *              errors as possible.
  75  *      EX_OSERR -- An operating system error has been detected.
  76  *              This is intended to be used for such things as "cannot
  77  *              fork", "cannot create pipe", or the like.  It includes
  78  *              things like getuid returning a user that does not
  79  *              exist in the passwd file.
  80  *      EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
  81  *              etc.) does not exist, cannot be opened, or has some
  82  *              sort of error (e.g., syntax error).
  83  *      EX_CANTCREAT -- A (user specified) output file cannot be
  84  *              created.
  85  *      EX_IOERR -- An error occurred while doing I/O on some file.
  86  *      EX_TEMPFAIL -- temporary failure, indicating something that
  87  *              is not really an error.  In sendmail, this means
  88  *              that a mailer (e.g.) could not create a connection,
  89  *              and the request should be reattempted later.
  90  *      EX_PROTOCOL -- the remote system returned something that
  91  *              was "not possible" during a protocol exchange.
  92  *      EX_NOPERM -- You did not have sufficient permission to
  93  *              perform the operation.  This is not intended for
  94  *              file system problems, which should use NOINPUT or
  95  *              CANTCREAT, but rather for higher level permissions.
