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