Hi all, What do people think of the idea of threads preserving their exit status?
The exit status would be either - a raised exception, or - a normally-returned value, or - nothing as yet, because the thread is still running. (thread-died-with-exception? thd) -> boolean? Returns #t if thd died from a raised exception, #f if thd exited through a normal return, or raises exn:fail:contract if thd hasn't exited yet. (thread-exception thd) -> (or/c exn? false?) Returns the exception that killed thd, #f if the thread returned normally, or raises exn:fail:contract if thd hasn't exited yet. (thread-result thd) -> any? Returns the value that thd's thunk returned, or raises exn:fail:contract if either thd hasn't exited yet or thd died from a raised exception. The existing (thread-dead?) and (thread-dead-evt) would be used unchanged. (Hmm - if a thread was killed, what would (thread-died-with-exception?) return?) Would it be difficult to implement? It'd require a change to the C code. Regards, Tony _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/dev
