 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.
