036:  *  SYSEXITS.H -- Exit status codes for system programs.
037:  *
038:  *      This include file attempts to categorize possible error
039:  *      exit statuses for system programs, notably delivermail
040:  *      and the Berkeley network.
041:  *
042:  *      Error numbers begin at EX__BASE to reduce the possibility of
043:  *      clashing with other exit statuses that random programs may
044:  *      already return.  The meaning of the codes is approximately
045:  *      as follows:
046:  *
047:  *      EX_USAGE -- The command was used incorrectly, e.g., with
048:  *              the wrong number of arguments, a bad flag, a bad
049:  *              syntax in a parameter, or whatever.
050:  *      EX_DATAERR -- The input data was incorrect in some way.
051:  *              This should only be used for user's data & not
052:  *              system files.
053:  *      EX_NOINPUT -- An input file (not a system file) did not
054:  *              exist or was not readable.  This could also include
055:  *              errors like "No message" to a mailer (if it cared
056:  *              to catch it).
057:  *      EX_NOUSER -- The user specified did not exist.  This might
058:  *              be used for mail addresses or remote logins.
059:  *      EX_NOHOST -- The host specified did not exist.  This is used
060:  *              in mail addresses or network requests.
061:  *      EX_UNAVAILABLE -- A service is unavailable.  This can occur
062:  *              if a support program or file does not exist.  This
063:  *              can also be used as a catchall message when something
064:  *              you wanted to do doesn't work, but you don't know
065:  *              why.
066:  *      EX_SOFTWARE -- An internal software error has been detected.
067:  *              This should be limited to non-operating system related
068:  *              errors as possible.
069:  *      EX_OSERR -- An operating system error has been detected.
070:  *              This is intended to be used for such things as "cannot
071:  *              fork", "cannot create pipe", or the like.  It includes
072:  *              things like getuid returning a user that does not
073:  *              exist in the passwd file.
074:  *      EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
075:  *              etc.) does not exist, cannot be opened, or has some
076:  *              sort of error (e.g., syntax error).
077:  *      EX_CANTCREAT -- A (user specified) output file cannot be
078:  *              created.
079:  *      EX_IOERR -- An error occurred while doing I/O on some file.
080:  *      EX_TEMPFAIL -- temporary failure, indicating something that
081:  *              is not really an error.  In sendmail, this means
082:  *              that a mailer (e.g.) could not create a connection,
083:  *              and the request should be reattempted later.
084:  *      EX_PROTOCOL -- the remote system returned something that
085:  *              was "not possible" during a protocol exchange.
086:  *      EX_NOPERM -- You did not have sufficient permission to
087:  *              perform the operation.  This is not intended for
088:  *              file system problems, which should use NOINPUT or
089:  *              CANTCREAT, but rather for higher level permissions.
