  16: **  SYSEXITS.H -- Exit status codes for system programs.
  17: **
  18: **	This include file attempts to categorize possible error
  19: **	exit statuses for system programs, notably delivermail
  20: **	and the Berkeley network.
  21: **
  22: **	Error numbers begin at EX__BASE to reduce the possibility of
  23: **	clashing with other exit statuses that random programs may
  24: **	already return.  The meaning of the codes is approximately
  25: **	as follows:
  26: **
  27: **	EX_USAGE -- The command was used incorrectly, e.g., with
  28: **		the wrong number of arguments, a bad flag, a bad
  29: **		syntax in a parameter, or whatever.
  30: **	EX_DATAERR -- The input data was incorrect in some way.
  31: **		This should only be used for user's data & not
  32: **		system files.
  33: **	EX_NOINPUT -- An input file (not a system file) did not
  34: **		exist or was not readable.  This could also include
  35: **		errors like "No message" to a mailer (if it cared
  36: **		to catch it).
  37: **	EX_NOUSER -- The user specified did not exist.  This might
  38: **		be used for mail addresses or remote logins.
  39: **	EX_NOHOST -- The host specified did not exist.  This is used
  40: **		in mail addresses or network requests.
  41: **	EX_UNAVAILABLE -- A service is unavailable.  This can occur
  42: **		if a support program or file does not exist.  This
  43: **		can also be used as a catchall message when something
  44: **		you wanted to do doesn't work, but you don't know
  45: **		why.
  46: **	EX_SOFTWARE -- An internal software error has been detected.
  47: **		This should be limited to non-operating system related
  48: **		errors as possible.
  49: **	EX_OSERR -- An operating system error has been detected.
  50: **		This is intended to be used for such things as "cannot
  51: **		fork", "cannot create pipe", or the like.  It includes
  52: **		things like getuid returning a user that does not
  53: **		exist in the passwd file.
  54: **	EX_OSFILE -- Some system file (e.g., /etc/passwd, /var/run/utmp,
  55: **		etc.) does not exist, cannot be opened, or has some
  56: **		sort of error (e.g., syntax error).
  57: **	EX_CANTCREAT -- A (user specified) output file cannot be
  58: **		created.
  59: **	EX_IOERR -- An error occurred while doing I/O on some file.
  60: **	EX_TEMPFAIL -- temporary failure, indicating something that
  61: **		is not really an error.  In sendmail, this means
  62: **		that a mailer (e.g.) could not create a connection,
  63: **		and the request should be reattempted later.
  64: **	EX_PROTOCOL -- the remote system returned something that
  65: **		was "not possible" during a protocol exchange.
  66: **	EX_NOPERM -- You did not have sufficient permission to
  67: **		perform the operation.  This is not intended for
  68: **		file system problems, which should use NOINPUT or
  69: **		CANTCREAT, but rather for higher level permissions.
  70: **		For example, kre uses this to restrict who students
  71: **		can send mail to.
  72: **
  73: **	Maintained by Eric Allman (eric@berkeley, ucbvax!eric) --
  74: **		please mail changes to me.
