16: ** SYSEXITS.H -- Exit status codes for system programs.
17: **
18: ** This include file attempts to categorize possible error
19: ** exit statuses for system programs, notably delivermail
20: ** and the Berkeley network.
21: **
22: ** Error numbers begin at EX__BASE to reduce the possibility of
23: ** clashing with other exit statuses that random programs may
24: ** already return. The meaning of the codes is approximately
25: ** as follows:
26: **
27: ** EX_USAGE -- The command was used incorrectly, e.g., with
28: ** the wrong number of arguments, a bad flag, a bad
29: ** syntax in a parameter, or whatever.
30: ** EX_DATAERR -- The input data was incorrect in some way.
31: ** This should only be used for user's data & not
32: ** system files.
33: ** EX_NOINPUT -- An input file (not a system file) did not
34: ** exist or was not readable. This could also include
35: ** errors like "No message" to a mailer (if it cared
36: ** to catch it).
37: ** EX_NOUSER -- The user specified did not exist. This might
38: ** be used for mail addresses or remote logins.
39: ** EX_NOHOST -- The host specified did not exist. This is used
40: ** in mail addresses or network requests.
41: ** EX_UNAVAILABLE -- A service is unavailable. This can occur
42: ** if a support program or file does not exist. This
43: ** can also be used as a catchall message when something
44: ** you wanted to do doesn't work, but you don't know
45: ** why.
46: ** EX_SOFTWARE -- An internal software error has been detected.
47: ** This should be limited to non-operating system related
48: ** errors as possible.
49: ** EX_OSERR -- An operating system error has been detected.
50: ** This is intended to be used for such things as "cannot
51: ** fork", "cannot create pipe", or the like. It includes
52: ** things like getuid returning a user that does not
53: ** exist in the passwd file.
54: ** EX_OSFILE -- Some system file (e.g., /etc/passwd, /var/run/utmp,
55: ** etc.) does not exist, cannot be opened, or has some
56: ** sort of error (e.g., syntax error).
57: ** EX_CANTCREAT -- A (user specified) output file cannot be
58: ** created.
59: ** EX_IOERR -- An error occurred while doing I/O on some file.
60: ** EX_TEMPFAIL -- temporary failure, indicating something that
61: ** is not really an error. In sendmail, this means
62: ** that a mailer (e.g.) could not create a connection,
63: ** and the request should be reattempted later.
64: ** EX_PROTOCOL -- the remote system returned something that
65: ** was "not possible" during a protocol exchange.
66: ** EX_NOPERM -- You did not have sufficient permission to
67: ** perform the operation. This is not intended for
68: ** file system problems, which should use NOINPUT or
69: ** CANTCREAT, but rather for higher level permissions.
70: ** For example, kre uses this to restrict who students
71: ** can send mail to.
72: **
73: ** Maintained by Eric Allman (eric@berkeley, ucbvax!eric) --
74: ** please mail changes to me.
