Z.IO.Network.SocketAddr

This module provides necessary types and constant for low level socket address manipulating.

name to address

data SocketAddr

IPv4 or IPv6 socket address, i.e. the sockaddr_in or sockaddr_in6 struct.

Example on JSON instance:

> JSON.encodeText  $ ipv6 "3731:54:65fe:2::a8" 9090
"{"addr":[14129,84,26110,2,0,0,0,168],"port":9090,"flow":0,"scope":0}"
> JSON.encodeText  $ ipv4 "128.14.32.1" 9090
"{"addr":[128,14,32,1],"port":9090}"

ipv4 :: HasCallStack => CBytes -> PortNumber -> SocketAddr

Convert a string containing an IPv4 addresses to a binary structure

This is partial function, wrong address will throw InvalidArgument exception.

ipv6 :: HasCallStack => CBytes -> PortNumber -> SocketAddr

Convert a string containing an IPv6 addresses to a binary structure

This is partial function, wrong address will throw InvalidArgument exception.

sockAddrFamily :: SocketAddr -> SocketFamily

withSocketAddr :: SocketAddr -> (Ptr SocketAddr -> IO a) -> IO a

Pass SocketAddr to FFI as pointer.

withSocketAddrUnsafe :: SocketAddr -> (MBA# SocketAddr -> IO a) -> IO a

Pass SocketAddr to FFI as pointer.

USE THIS FUNCTION WITH UNSAFE FFI CALL ONLY.

sizeOfSocketAddr :: SocketAddr -> CSize

withSocketAddrStorage :: (Ptr SocketAddr -> IO ()) -> IO SocketAddr

Allocate space for sockaddr_storage and pass to FFI.

withSocketAddrStorageUnsafe :: (MBA# SocketAddr -> IO ()) -> IO SocketAddr

Allocate space for sockaddr_storage and pass to FFI.

USE THIS FUNCTION WITH UNSAFE FFI CALL ONLY.

sizeOfSocketAddrStorage :: CSize

IPv4 address

newtype IPv4

Independent of endianness. For example 127.0.0.1 is stored as (127, 0, 0, 1).

For direct manipulation prefer ipv4AddrToTuple and tupleToIPv4Addr.

JSON instance encode ipv4 address into an array with 4 Word8 octets.
