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