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