IOSpec-0.2: A pure specification of the IO monad.

Safe HaskellNone



A pure specification of forkIO.



data ForkS a Source

An expression of type IOSpec ForkS a corresponds to an IO computation that uses forkIO and returns a value of type a.

By itself, ForkS is not terribly useful. You will probably want to use IOSpec (ForkS :+: MVarS) or IOSpec (ForkS :+: STMS).

forkIO :: (Executable f, ForkS :<: g) => IOSpec f a -> IOSpec g ThreadIdSource

The forkIO function forks off a new thread.
