Z.IO.Network.SocketAddr

Description

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

Synopsis

name to address

data SocketAddr Source #

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 Source #

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 Source #

Convert a string containing an IPv6 addresses to a binary structure

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

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

Pass SocketAddr to FFI as pointer.

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

Pass SocketAddr to FFI as pointer.

USE THIS FUNCTION WITH UNSAFE FFI CALL ONLY.

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

Allocate space for sockaddr_storage and pass to FFI.

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

Allocate space for sockaddr_storage and pass to FFI.

USE THIS FUNCTION WITH UNSAFE FFI CALL ONLY.

IPv4 address

newtype IPv4 Source #

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.

ipv4None :: IPv4 Source #

255.255.255.255

ipv4AddrToTuple :: IPv4 -> (Word8, Word8, Word8, Word8) Source #

Converts IPv4 to representation-independent IPv4 quadruple. For example for 127.0.0.1 the function will return (127, 0, 0, 1) regardless of host endianness.

tupleToIPv4Addr :: (Word8, Word8, Word8, Word8) -> IPv4 Source #

Converts IPv4 quadruple to IPv4.

IPv6 address

data IPv6 Source #

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

For direct manipulation prefer ipv6AddrToTuple and tupleToIPv6Addr.

JSON instance encode ipv6 address into an array with 8 Word16 octets.
