23: ** SYSEXITS.H -- Exit status codes for system programs.
24: **
25: ** This include file attempts to categorize possible error
26: ** exit statuses for system programs, notably delivermail
27: ** and the Berkeley network.
28: **
29: ** Error numbers begin at EX__BASE to reduce the possibility of
30: ** clashing with other exit statuses that random programs may
31: ** already return. The meaning of the codes is approximately
32: ** as follows:
33: **
34: ** EX_USAGE -- The command was used incorrectly, e.g., with
35: ** the wrong number of arguments, a bad flag, a bad
36: ** syntax in a parameter, or whatever.
37: ** EX_DATAERR -- The input data was incorrect in some way.
38: ** This should only be used for user's data & not
39: ** system files.
40: ** EX_NOINPUT -- An input file (not a system file) did not
41: ** exist or was not readable. This could also include
42: ** errors like "No message" to a mailer (if it cared
43: ** to catch it).
44: ** EX_NOUSER -- The user specified did not exist. This might
45: ** be used for mail addresses or remote logins.
46: ** EX_NOHOST -- The host specified did not exist. This is used
47: ** in mail addresses or network requests.
48: ** EX_UNAVAILABLE -- A service is unavailable. This can occur
49: ** if a support program or file does not exist. This
50: ** can also be used as a catchall message when something
51: ** you wanted to do doesn't work, but you don't know
52: ** why.
53: ** EX_SOFTWARE -- An internal software error has been detected.
54: ** This should be limited to non-operating system related
55: ** errors as possible.
56: ** EX_OSERR -- An operating system error has been detected.
57: ** This is intended to be used for such things as "cannot
58: ** fork", "cannot create pipe", or the like. It includes
59: ** things like getuid returning a user that does not
60: ** exist in the passwd file.
61: ** EX_OSFILE -- Some system file (e.g., /etc/passwd, /etc/utmp,
62: ** etc.) does not exist, cannot be opened, or has some
63: ** sort of error (e.g., syntax error).
64: ** EX_CANTCREAT -- A (user specified) output file cannot be
65: ** created.
66: ** EX_IOERR -- An error occurred while doing I/O on some file.
67: ** EX_TEMPFAIL -- temporary failure, indicating something that
68: ** is not really an error. In sendmail, this means
69: ** that a mailer (e.g.) could not create a connection,
70: ** and the request should be reattempted later.
71: ** EX_PROTOCOL -- the remote system returned something that
72: ** was "not possible" during a protocol exchange.
73: ** EX_NOPERM -- You did not have sufficient permission to
74: ** perform the operation. This is not intended for
75: ** file system problems, which should use NOINPUT or
76: ** CANTCREAT, but rather for higher level permissions.
77: ** For example, kre uses this to restrict who students
78: ** can send mail to.
79: **
80: ** Maintained by Eric Allman (eric@berkeley, ucbvax!eric) --
81: ** please mail changes to me.
