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