21: ** SYSEXITS.H -- Exit status codes for system programs.
22: **
23: ** This include file attempts to categorize possible error
24: ** exit statuses for system programs, notably delivermail
25: ** and the Berkeley network.
26: **
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
30: ** as follows:
31: **
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
37: ** system files.
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
41: ** to catch it).
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
50: ** why.
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
63: ** created.
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
76: ** can send mail to.
77: **
78: ** Maintained by Eric Allman (eric@berkeley, ucbvax!eric) --
79: ** please mail changes to me.
