recvPacketOr :: Udp -> IO (Either String Packet)

close :: Udp -> IO ()

udpPort :: Integral n => Udp -> IO n

Return the port number associated with the Udp socket.

udp_send_data :: Udp -> ByteString -> IO ()

Send data over Udp using send.

udp_sendAll_data :: Udp -> ByteString -> IO ()

Send data over Udp using sendAll.

udp_send_packet :: Udp -> PacketOf Message -> IO ()

Send packet over Udp.

udp_recv_packet :: Udp -> IO (PacketOf Message)

Receive packet over Udp.

udp_recv_packet_or :: Udp -> IO (Either String Packet)

udp_close :: Udp -> IO ()

Close Udp.

with_udp :: IO Udp -> (Udp -> IO t) -> IO t

Bracket Udp communication.

udp_socket :: (Socket -> SockAddr -> IO ()) -> String -> Int -> IO Udp

Create and initialise Udp socket.

set_udp_opt :: SocketOption -> Int -> Udp -> IO ()

Set option, ie. Broadcast or RecvTimeOut.

get_udp_opt :: SocketOption -> Udp -> IO Int

Get option.

openUdp :: String -> Int -> IO Udp

import Control.Concurrent

let u0 = udpServer "127.0.0.1" 57300
t0 <- forkIO (Fd.withTransport u0 (\fd -> forever (Fd.recvMessage fd >>= print >> print "Received message, continuing")))
killThread t0

let u1 = openUdp "127.0.0.1" 57300
Fd.withTransport u1 (\fd -> Fd.sendMessage fd (Packet.message "/n" []))

udp_server :: Int -> IO Udp

Variant of udpServer that doesn't require the host address.

sendTo :: Udp -> PacketOf Message -> SockAddr -> IO ()

Send to specified address using 'C.sendAllTo.

recvFrom :: Udp -> IO (PacketOf Message, SockAddr)

Recv variant to collect message source address.
