valuerunUDPClient

:: HostName
-> ServiceName
-> Socket -> SockAddr -> IO a
-> IO a

Running a UDP client with a socket. The client action takes a socket and server's socket address. They should be used with sendTo.

valuerunUDPServer :: Maybe HostName -> ServiceName -> (Socket -> IO a) -> IO a

Running a UDP server with an open socket in a single Haskell thread.

valuerunUDPServerFork

:: [HostName]
-> ServiceName
-> Socket -> ByteString -> IO ()
-> IO ()

Running a UDP server with a connected socket in each Haskell thread. The first request is given to the server. Suppose that the server is serving on addrS:portS and a client connects to the service from addrC:portC. A connected socket is created by binding to *:portS and connecting to addrC:portC, resulting in (UDP,addrS:portS,addrC:portC) where addrS is given magically. This approach is fragile due to NAT rebidings.
