How to get IO String from Network.Socket.ByteString.recv method (Dinesh Amerasekara) ---------------------------------------------------------------------- Message: 1 Date: Sun, 20 May 2018 07:52:33 +0000 (UTC) From: Dinesh Amerasekara <ddines...@yahoo.com> To: beginners@haskell.org Subject: [Haskell-beginners] How to get IO String from Network.Socket.ByteString.recv method Message-ID: <1643328860.3250152.1526802753...@mail.yahoo.com> Content-Type: text/plain; charset="utf-8" Hi, I am unable to compile the below code. import Network.Socket hiding(recv) import Network.Socket.ByteString as S (recv) import qualified Data.ByteString.Lazy.Char8 as Char8 getMessage :: Socket -> IO String getMessage sock = Char8.unpack <$> S.recv sock 8888 It gives the below error. Couldn't match type ‘Data.ByteString.Internal.ByteString’ with ‘ByteString’NB: ‘ByteString’ is defined in ‘Data.ByteString.Lazy.Internal’ ‘Data.ByteString.Internal.ByteString’ is defined in ‘Data.ByteString.Internal’ Expected type: IO ByteString Actual type: IO Data.ByteString.Internal.ByteString In the second argument of ‘(<$>)’, namely ‘recv sock 8888’In the expression: unpack <$> recv sock 8888In an equation for ‘getMsg’: getMsg sock = unpack <$> recv sock 8888 Can somebody tell me how I can return the IO String using Network.Socket.ByteString.recv?
