- * 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.
