- ** 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.
- ** 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.
