Hi Dave, Why would the posix _exit() be unsatisfactory? thanks :-) Jason L. Froebe No one has seen what you have seen, and until that happens, we're all going to think that you're nuts. - Jack O'Neil, Stargate SG-1	[reply]

Why would the posix _exit() be unsatisfactory? Because if for any reason whatsoever, a child process somehow accidently exits in any other way, the parent is screwed. So it's a bit of a fragile mechanism. Dave.	[reply]

Why would the posix _exit() be unsatisfactory? One word. Kludge. Fixing the underlying OS bug would be satisfactory, everything else is a workaround and therefore not very satisfactory. That said something that works is by definition beter than something that does not. cheers tachyon	[reply]

Hey Dave, just out of curiousity, do you have any documentation on this Solaris 'feature'? Also, do you know offhand if calling `POSIX::_exit()` will honor DESTROY hints like DBH's InactiveDestroy? I'll test all this later today when I get to work, but any heads-up on specifics would be great. Thanks... Ezra	[reply] [d/l]

do you have any documentation on this Solaris 'feature'? Well, I know about it because of a Perl bug report from a few weeks ago. I'm not sure whether we got as far as resolving whether it's Perl's or Solaris's fault, and I haven't had time yet to go back and look at it further. Solaris is trying to backout of a stdio buffered read before exiting. do you know offhand if calling POSIX::_exit() will honor DESTROY _exit() does an immediate process exit without doing any cleanup of any kind, either at the Perl or C level.

Very interesting, and near what I was expecting. I need further testing with this. Thanks...	[reply]
