#3: Cannot call connect with a socket that is already bound. ---------------------+------------------------------------------------------ Reporter: igloo | Owner: Type: defect | Status: new Priority: major | Milestone: Component: network | Version: Keywords: | ---------------------+------------------------------------------------------ Originally reported here: http://hackage.haskell.org/trac/ghc/ticket/2784 ---- {{{

import Network.Socket sock <- socket AF_INET Datagram 0 Loading package parsec-2.1.0.1 ... linking ... done. Loading package network-2.2.0.1 ... linking ... done. bindSocket sock (SockAddrInet aNY_PORT iNADDR_ANY) connect sock undefined *** Exception: user error (connect: can't peform connect on socket in status Bound) }}} Network.Socket.connect checks the !SocketStatus of the socket: {{{ if currentStatus /= NotConnected }}}

From [http://www.opengroup.org/onlinepubs/000095399/functions/connect.html The Open Group Base Specifications Issue 6]: "If the socket has not already been bound to a local address, connect() shall bind it to an address which, unless the socket's address family is AF_UNIX, is an unused local address." -- Ticket URL: http://trac.haskell.org/network/ticket/3 network http://projects.haskell.org/network/ Networking-related facilities
