# *  SYSEXITS.H -- Exit status codes for system programs.
# *
# *      This include file attempts to categorize possible error
# *      exit statuses for system programs, notably delivermail
# *      and the Berkeley network.
# *
# *      Error numbers begin at EX__BASE to reduce the possibility of
# *      clashing with other exit statuses that random programs may
# *      already return.  The meaning of the codes is approximately
# *      as follows:
# *
# *      EX_USAGE -- The command was used incorrectly, e.g., with
# *              the wrong number of arguments, a bad flag, a bad
# *              syntax in a parameter, or whatever.
# *      EX_DATAERR -- The input data was incorrect in some way.
# *              This should only be used for user's data & not
# *              system files.
# *      EX_NOINPUT -- An input file (not a system file) did not
# *              exist or was not readable.  This could also include
# *              errors like "No message" to a mailer (if it cared
# *              to catch it).
# *      EX_NOUSER -- The user specified did not exist.  This might
# *              be used for mail addresses or remote logins.
# *      EX_NOHOST -- The host specified did not exist.  This is used
# *              in mail addresses or network requests.
# *      EX_UNAVAILABLE -- A service is unavailable.  This can occur
# *              if a support program or file does not exist.  This
# *              can also be used as a catchall message when something
# *              you wanted to do doesn't work, but you don't know
# *              why.
# *      EX_SOFTWARE -- An internal software error has been detected.
# *              This should be limited to non-operating system related
# *              errors as possible.
# *      EX_OSERR -- An operating system error has been detected.
# *              This is intended to be used for such things as "cannot
# *              fork", "cannot create pipe", or the like.  It includes
# *              things like getuid returning a user that does not
# *              exist in the passwd file.
# *      EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
# *              etc.) does not exist, cannot be opened, or has some
# *              sort of error (e.g., syntax error).
# *      EX_CANTCREAT -- A (user specified) output file cannot be
# *              created.
# *      EX_IOERR -- An error occurred while doing I/O on some file.
# *      EX_TEMPFAIL -- temporary failure, indicating something that
# *              is not really an error.  In sendmail, this means
# *              that a mailer (e.g.) could not create a connection,
# *              and the request should be reattempted later.
# *      EX_PROTOCOL -- the remote system returned something that
# *              was "not possible" during a protocol exchange.
# *      EX_NOPERM -- You did not have sufficient permission to
# *              perform the operation.  This is not intended for
# *              file system problems, which should use NOINPUT or
# *              CANTCREAT, but rather for higher level permissions.
