** 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
** 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
** 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.
** For example, kre uses this to restrict who students
** can send mail to.
** Maintained by Eric Allman (eric@berkeley, ucbvax!eric) --
** please mail changes to me.
