Is pthread_cancel() still a no go to be used in threads::interrupt implementation?
pthread_cancel is no-go because it has different semantics and cannot be translated into an exception.
If you mean that its semantics are different because pthread_cancel is intended to be an unstoppable, non-ignorable command, but someone can always do a catch(...){}, I think that's silly (and I've made that clear to the Posix people—I'm not just picking on you). Even in the `C' world there's nothing to stop me from either a) disabling cancellation or b) doing something in a cancellation handler that never terminates (including re-trying whatever operation was cancelled). -- Dave Abrahams BoostPro Computing http://www.boostpro.com
