The purpose of this test driver is to test TCP Stream sockets.
All values have been hard coded since the BSD library is not used to
query the databases for the values. In therory this code is thus not
portable but net007/Main.hs provides a portable version using the BSD
module.
This creates a stream socket bound to port 5000 and waits for incoming
messages it then reads all available data before closing the
connection to that peer.
No form of error checking is provided other than that already provided
by module SocketPrim.
TESTS:
socket
bindSocket
listen
accept
readSocket
sClose
-}
module Main where
import SocketPrim
main = do
s <- socket AF_INET Stream 6
bindSocket s (SockAddrInet (fromIntegral 5000) iNADDR_ANY)
listen s 5
let
loop =
accept s >>= \ (s',peerAddr) ->
putStr "*** Start of Transfer ***\n" >>
h <- socketToHandle s'
let
read_all =
b <- hEOF h
c <- hGetChar h
putChar c
if nbytes /= 0 then
putStr str >>
read_all
else
putStr "\n*** End of Transfer ***\n" >>
sClose s'
