The supported+-- flags are as follows:+--+-- [@AI_PASSIVE@] If no 'HostName' value is provided, the network+-- address in each 'SockAddr'+-- will be left as a "wild card", i.e. as either 'iNADDR_ANY'+-- or 'iN6ADDR_ANY'. This is useful for server applications that+-- will accept connections from any client.+--+-- [@AI_CANONNAME@] The 'addrCanonName' field of the first returned+-- 'AddrInfo' will contain the "canonical name" of the host.+--+-- [@AI_NUMERICHOST@] The 'HostName' argument /must/ be a numeric+-- address in string form, and network name lookups will not be+-- attempted.+-- +-- /Note/: Although the following flags are required by RFC 3493, they+-- may not have an effect on all platforms, because the underlying+-- network stack may not support them. To see whether a flag from the+-- list below will have any effect, call 'addrInfoFlagImplemented'.+--+-- [@AI_NUMERICSERV@] The 'ServiceName' argument /must/ be a port+-- number in string form, and service name lookups will not be+-- attempted.+--+-- [@AI_ADDRCONFIG@] The list of returned 'AddrInfo' values will+-- only contain IPv4 addresses if the local system has at least+-- one IPv4 interface configured, and likewise for IPv6.+--+-- [@AI_V4MAPPED@] If an IPv6 lookup is performed, and no IPv6+-- addresses are found, IPv6-mapped IPv4 addresses will be+-- returned.+--+-- [@AI_ALL@] If 'AI_ALL' is specified, return all matching IPv6 and+-- IPv4 addresses. Otherwise, this flag has no effect.+-- +-- You must provide a 'Just' value for at least one of the 'HostName'+-- or 'ServiceName' arguments. 'HostName' can be either a numeric+-- network address (dotted quad for IPv4, colon-separated hex for+-- IPv6) or a hostname. In the latter case, its addresses will be+-- looked up unless 'AI_NUMERICHOST' is specified as a hint. If you+-- do not provide a 'HostName' value /and/ do not set 'AI_PASSIVE' as+-- a hint, network addresses in the result will contain the address of+-- the loopback interface.+--+-- If the query fails, this function throws an IO exception instead of+-- returning an empty list. Otherwise, it returns a non-empty list+-- of 'AddrInfo' values.+--+-- There are several reasons why a query might result in several+-- values. For example, the queried-for host could be multihomed, or+-- the service might be available via several protocols.+--+-- Note: the order of arguments is slightly different to that defined+-- for @getaddrinfo@ in RFC 2553. The 'AddrInfo' parameter comes first+-- to make partial application easier.+--+-- Example:+-- @+-- let hints = defaultHints { addrFlags = [AI_ADDRCONFIG, AI_CANONNAME] }+-- addrs <- getAddrInfo (Just hints) (Just "www.haskell.org") (Just "http")+-- let addr = head addrs+-- sock <- socket (addrFamily addr) (addrSocketType addr) (addrProtocol addr)+-- connect sock (addrAddress addr)+-- @++getAddrInfo :: Maybe AddrInfo -- ^ preferred socket type or protocol+ -> Maybe HostName -- ^ host name to look up+ -> Maybe ServiceName -- ^ service name to look up+ -> IO [AddrInfo] -- ^ resolved addresses, with "best" first++getAddrInfo hints node service =+ maybeWith withCString node $ \c_node ->+ maybeWith withCString service $ \c_service ->+ maybeWith with hints $ \c_hints ->+ alloca $ \ptr_ptr_addrs -> do+ ret <- c_getaddrinfo c_node c_service c_hints ptr_ptr_addrs+ case ret of+ 0 -> do ptr_addrs <- peek ptr_ptr_addrs+ ais <- followAddrInfo ptr_addrs+ c_freeaddrinfo ptr_addrs+ return ais+ _ -> do err <- gai_strerror ret+ ioError (IOError Nothing NoSuchThing "getAddrInfo" err+ Nothing)++followAddrInfo :: Ptr AddrInfo -> IO [AddrInfo]++followAddrInfo ptr_ai | ptr_ai == nullPtr = return []+ | otherwise = do+ a <- peek ptr_ai+ as <- (#peek struct addrinfo, ai_next) ptr_ai >>= followAddrInfo+ return (a:as)++foreign import ccall safe "getaddrinfo"+ c_getaddrinfo :: CString -> CString -> Ptr AddrInfo -> Ptr (Ptr AddrInfo)+ -> IO CInt++foreign import ccall safe "freeaddrinfo"+ c_freeaddrinfo :: Ptr AddrInfo -> IO ()++gai_strerror :: CInt -> IO String++gai_strerror n = c_gai_strerror n >>= peekCString++foreign import ccall safe "gai_strerror"+ c_gai_strerror :: CInt -> IO CString++withCStringIf :: Bool -> Int -> (CSize -> CString -> IO a) -> IO a+withCStringIf False _ f = f 0 nullPtr+withCStringIf True n f = allocaBytes n (f (fromIntegral n))+ +-- | Resolve an address to a host or service name.+-- This function is protocol independent.+--+-- The list of 'NameInfoFlag' values controls query behaviour. The+-- supported flags are as follows:+--+-- [@NI_NOFQDN@] If a host is local, return only the+-- hostname part of the FQDN.+--+-- [@NI_NUMERICHOST@] The name of the host is not+-- looked up. Instead, a numeric representation of the host's+-- address is returned. For an IPv4 address, this will be a+-- dotted-quad string. For IPv6, it will be colon-separated+-- hexadecimal.+--+-- [@NI_NUMERICSERV@] The name of the service is not+-- looked up. Instead, a numeric representation of the+-- service is returned.+--+-- [@NI_NAMEREQD@] If the hostname cannot be looked up, an IO error+-- is thrown.+--+-- [@NI_DGRAM@] Resolve a datagram-based service name. This is+-- required only for the few protocols that have different port+-- numbers for their datagram-based versions than for their+-- stream-based versions.+--+-- Hostname and service name lookups can be expensive. You can+-- specify which lookups to perform via the two 'Bool' arguments. If+-- one of these is 'False', the corresponding value in the returned+-- tuple will be 'Nothing', and no lookup will be performed.+--+-- If a host or service's name cannot be looked up, then the numeric+-- form of the address or service will be returned.+--+-- If the query fails, this function throws an IO exception.+--+-- Example:+-- @+-- (hostName, _) <- getNameInfo [] True False myAddress+-- @++getNameInfo :: [NameInfoFlag] -- ^ flags to control lookup behaviour+ -> Bool -- ^ whether to look up a hostname+ -> Bool -- ^ whether to look up a service name+ -> SockAddr -- ^ the address to look up+ -> IO (Maybe HostName, Maybe ServiceName)++getNameInfo flags doHost doService addr =+ withCStringIf doHost (#const NI_MAXHOST) $ \c_hostlen c_host ->+ withCStringIf doService (#const NI_MAXSERV) $ \c_servlen c_serv -> do+ withSockAddr addr $ \ptr_addr sz -> do+ ret <- c_getnameinfo ptr_addr (fromIntegral sz) c_host c_hostlen+ c_serv c_servlen (packBits niFlagMapping flags)+ case ret of+ 0 -> do+ let peekIf doIf c_val = if doIf+ then liftM Just $ peekCString c_val+ else return Nothing+ host <- peekIf doHost c_host+ serv <- peekIf doService c_serv+ return (host, serv)+ _ -> do err <- gai_strerror ret+ ioError (IOError Nothing NoSuchThing "getNameInfo" err+ Nothing)++foreign import ccall safe "getnameinfo"+ c_getnameinfo :: Ptr SockAddr -> CInt{-CSockLen???-} -> CString -> CSize -> CString+ -> CSize -> CInt -> IO CInt #endif mkInvalidRecvArgError :: String -> IOError
