21 ** SYSEXITS.H -- Exit status codes for system programs.
23 ** This include file attempts to categorize possible error
24 ** exit statuses for system programs, notably delivermail
25 ** and the Berkeley network.
27 ** Error numbers begin at EX__BASE to reduce the possibility of
28 ** clashing with other exit statuses that random programs may
29 ** already return. The meaning of the codes is approximately
32 ** EX_USAGE -- The command was used incorrectly, e.g., with
33 ** the wrong number of arguments, a bad flag, a bad
34 ** syntax in a parameter, or whatever.
35 ** EX_DATAERR -- The input data was incorrect in some way.
36 ** This should only be used for user's data & not
38 ** EX_NOINPUT -- An input file (not a system file) did not
39 ** exist or was not readable. This could also include
40 ** errors like "No message" to a mailer (if it cared
42 ** EX_NOUSER -- The user specified did not exist. This might
43 ** be used for mail addresses or remote logins.
44 ** EX_NOHOST -- The host specified did not exist. This is used
45 ** in mail addresses or network requests.
46 ** EX_UNAVAILABLE -- A service is unavailable. This can occur
47 ** if a support program or file does not exist. This
48 ** can also be used as a catchall message when something
49 ** you wanted to do doesn't work, but you don't know
51 ** EX_SOFTWARE -- An internal software error has been detected.
52 ** This should be limited to non-operating system related
53 ** errors as possible.
54 ** EX_OSERR -- An operating system error has been detected.
55 ** This is intended to be used for such things as "cannot
56 ** fork", "cannot create pipe", or the like. It includes
57 ** things like getuid returning a user that does not
58 ** exist in the passwd file.
59 ** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
60 ** etc.) does not exist, cannot be opened, or has some
61 ** sort of error (e.g., syntax error).
62 ** EX_CANTCREAT -- A (user specified) output file cannot be
64 ** EX_IOERR -- An error occurred while doing I/O on some file.
65 ** EX_TEMPFAIL -- temporary failure, indicating something that
66 ** is not really an error. In sendmail, this means
67 ** that a mailer (e.g.) could not create a connection,
68 ** and the request should be reattempted later.
69 ** EX_PROTOCOL -- the remote system returned something that
70 ** was "not possible" during a protocol exchange.
71 ** EX_NOPERM -- You did not have sufficient permission to
72 ** perform the operation. This is not intended for
73 ** file system problems, which should use NOINPUT or
74 ** CANTCREAT, but rather for higher level permissions.
75 ** For example, kre uses this to restrict who students

79 ** please mail changes to me.
