Re: Network on Win98: failed - socket - no error ??

Did you remember to use 'withSocketsDo'? If you
did, it would help to see the code that's failing
for you (trivial or not.)
Did. But you're right, of course, so here's the current code.

-- Server.hs
module Main where

import Network
import IO
import System

main = withSocketsDo $ do
  (pnum:_) <- getArgs
  let p = fromIntegral $ read pnum
  s <- listenOn $ PortNumber p
  (h, host, portnr) <- accept s
  hSetBuffering h LineBuffering
  loop h
  where
    loop h = do
      l <- hGetLine h 
      putStrLn $ "SERVER: "++l
      loop h

-- Client.hs
module Main where

import Network
import IO
import System

main = withSocketsDo $ do
  (pnum:_) <- getArgs
  let p = fromIntegral $ read pnum
  h <- connectTo "localhost" $ PortNumber p
  hSetBuffering h LineBuffering
  loop h
  where
    loop h = do
      l <- getLine
      putStrLn $ "CLIENT: "++l
      hPutStrLn h l
      loop h

Subject: Network on Win98: failed - socket - no error ??

I'm playing with the Network library (the recommended portable way?) and
have a surprising problem with a simple client/server example. As the same
program works fine on Solaris and Win2k, I suspect its a standard
"feature"
and someone here with more network programming experience might be
able to enlighten me?
- Server: listenOn port, then accept handle and enter loop, echoing from
    handle to stdout
- Client: connectTo "localhost" port, then enter loop echoing from
    stdin to handle
Both programs work on Solaris and Win2k, but fail on Win98, with:
Fail: failed
    Action: socket
    Reason: No error
which would be merely amusing, I guess, if I knew what it meant, and
what to do about it?
Cheers,
Claus
