forkFinally :: IO a -> (Either SomeException a -> IO ()) -> IO ThreadId #
Fork a thread and call the supplied function when the thread is about to terminate, with an exception or a returned value. The function is called with asynchronous exceptions masked.
forkFinally action and_then =
mask $ \restore ->
forkIO $ try (restore action) >>= and_thenThis function is useful for informing the parent when a child terminates, for example.
Since: 4.6.0.0
forkOSWithUnmask :: ((forall a. IO a -> IO a) -> IO ()) -> IO ThreadId #
Like forkIOWithUnmask, but the child thread is a bound thread,
as with forkOS.
