But exit(-1) gives the exit status (reported by $? in sh and
WEXITSTATUS) being 255, so how could you get -1 ? I've seen something
like this when I wrote a dodgy bit of perl which did something like:
$SIG{CHLD} = { 1 while wait != -1 };
# ... stuff ...
system "foo", "bar", "baz";
die "foo exit status was $?" if $? != 0;
In that case, $? may well be -1, since the CHLD handler's wait will
pick up the dead child, and the system's wait will get ECHILD, I
beleive. Whether this is what you're doing or not I don't know, you'd
probably have to give people more to work on, e.g. how you getting the
return value ($? in sh/perl, wait() and friends in C, etc...)
Just a thought, anyway, you'll probably have to wait for Philip to give
the correct answer.
