Re: [Haskell-cafe] Lazy IO with recursive reads?

Hi Fabian

From the source viewable in the Haddock docs supplied with GHC

- hGetContents calls lazyRead: hGetContents :: Handle -> IO String hGetContents handle = wantReadableHandle "hGetContents" handle $ \handle_ -> do xs <- lazyRead handle return (handle_{ haType=SemiClosedHandle}, xs ) - lazyRead : lazyRead :: Handle -> IO String lazyRead handle = unsafeInterleaveIO $ <<stuff>> hGetContents is using unsafeInterleaveIO already so you don't have to.
