  17 **  SYSEXITS.H -- Exit status codes for system programs.
  18 **
  19 **      This include file attempts to categorize possible error
  20 **      exit statuses for system programs, notably delivermail
  21 **      and the Berkeley network.
  22 **
  23 **      Error numbers begin at EX__BASE to reduce the possibility of
  24 **      clashing with other exit statuses that random programs may
  25 **      already return.  The meaning of the codes is approximately
  26 **      as follows:
  27 **
  28 **      EX_USAGE -- The command was used incorrectly, e.g., with
  29 **              the wrong number of arguments, a bad flag, a bad
  30 **              syntax in a parameter, or whatever.
  31 **      EX_DATAERR -- The input data was incorrect in some way.
  32 **              This should only be used for user's data & not
  33 **              system files.
  34 **      EX_NOINPUT -- An input file (not a system file) did not
  35 **              exist or was not readable.  This could also include
  36 **              errors like "No message" to a mailer (if it cared
  37 **              to catch it).
  38 **      EX_NOUSER -- The user specified did not exist.  This might
  39 **              be used for mail addresses or remote logins.
  40 **      EX_NOHOST -- The host specified did not exist.  This is used
  41 **              in mail addresses or network requests.
  42 **      EX_UNAVAILABLE -- A service is unavailable.  This can occur
  43 **              if a support program or file does not exist.  This
  44 **              can also be used as a catchall message when something
  45 **              you wanted to do doesn't work, but you don't know
  46 **              why.
  47 **      EX_SOFTWARE -- An internal software error has been detected.
  48 **              This should be limited to non-operating system related
  49 **              errors as possible.
  50 **      EX_OSERR -- An operating system error has been detected.
  51 **              This is intended to be used for such things as "cannot
  52 **              fork", "cannot create pipe", or the like.  It includes
  53 **              things like getuid returning a user that does not
  54 **              exist in the passwd file.
  55 **      EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
  56 **              etc.) does not exist, cannot be opened, or has some
  57 **              sort of error (e.g., syntax error).
  58 **      EX_CANTCREAT -- A (user specified) output file cannot be
  59 **              created.
  60 **      EX_IOERR -- An error occurred while doing I/O on some file.
  61 **      EX_TEMPFAIL -- temporary failure, indicating something that
  62 **              is not really an error.  In sendmail, this means
  63 **              that a mailer (e.g.) could not create a connection,
  64 **              and the request should be reattempted later.
  65 **      EX_PROTOCOL -- the remote system returned something that
  66 **              was "not possible" during a protocol exchange.
  67 **      EX_NOPERM -- You did not have sufficient permission to
  68 **              perform the operation.  This is not intended for
  69 **              file system problems, which should use NOINPUT or
  70 **              CANTCREAT, but rather for higher level permissions.
