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