16 # This test checks both $_exitcode and $_exitsignal variables. The
17 # purpose of this checking is to ensure that the variables are
18 # mutually exclusive
, i.e.
, that when $_exitsignal is
set, $_exitcode
19 # is not
, and vice
-versa. This mutual exclusion happens because
if an
20 # inferior exited
(either successfully or not
), it certainly was not
21 # killed by a
signal. However
, if it was killed by an uncaught
22 #
signal, then there is no way
for it to have exited.
