forkIO package:threads

forkIO :: IO a -> IO (ThreadId, IO (Result a))

Like Control.Concurrent.forkIO but returns a computation that when executed blocks until the thread terminates then returns the final value of the thread.

forkIO :: ThreadGroup -> IO a -> IO (ThreadId, IO (Result a))

threads Control.Concurrent.Thread.Group

Same as Control.Concurrent.Thread.forkIO but additionaly adds the thread to the group.

forkIOWithUnmask :: ((forall b . IO b -> IO b) -> IO a) -> IO (ThreadId, IO (Result a))

threads Control.Concurrent.Thread

Like Control.Concurrent.forkIOWithUnmask but returns a computation that when executed blocks until the thread terminates then returns the final value of the thread.

forkIOWithUnmask :: ThreadGroup -> ((forall b . IO b -> IO b) -> IO a) -> IO (ThreadId, IO (Result a))

threads Control.Concurrent.Thread.Group

Same as Control.Concurrent.Thread.forkIOWithUnmask but additionaly adds the thread to the group.
