parseIPv4 : String -> SocketAddress

  Parses a textual representation of an IPv4 address into a SocketAddress

getSocketFamily : Int -> Maybe SocketFamily
record UDPRecvData

  remote_addr : (rec : UDPAddrInfo) -> SocketAddress
  remote_port : (rec : UDPAddrInfo) -> Port
interface ToCode
  toCode : ToCode a => a -> Int
data SocketType : Type

  Socket Types.

  NotASocket : SocketType

    Not a socket, used in certain operations

  Stream : SocketType

    TCP

  Datagram : SocketType

    UDP

  RawSocket : SocketType

    Raw sockets

data SocketFamily : Type

  Socket Families

  The ones that people might actually use. We're not going to need US
  Government proprietary ones.

  AF_UNSPEC : SocketFamily

    Unspecified

  AF_INET : SocketFamily

    IP / UDP etc. IPv4

  AF_INET6 : SocketFamily

    IP / UDP etc. IPv6

SocketError : Type

  SocketError: Error thrown by a socket operation

SocketDescriptor : Type

  SocketDescriptor: Native C Socket Descriptor

data SocketAddress : Type

  Network Addresses

  IPv4Addr : Int -> Int -> Int -> Int -> SocketAddress
  IPv6Addr : SocketAddress

    Not implemented (yet)

  Hostname : String -> SocketAddress
  InvalidAddress : SocketAddress

    Used when there's a parse error

record Socket

  The metadata about a socket

  MkSocket : (descriptor : SocketDescriptor) -> (family : SocketFamily) -> (socketType : SocketType) -> (protocolNumber : ProtocolNumber) -> Socket
  descriptor : (rec : Socket) -> SocketDescriptor
  family : (rec : Socket) -> SocketFamily
  socketType : (rec : Socket) -> SocketType
  protocolNumber : (rec : Socket) -> ProtocolNumber
ResultCode : Type
ProtocolNumber : Type

  Protocol Number.

  Generally good enough to just set it to 0.

Port : Type
MkUDPRecvData : (remote_addr : SocketAddress) -> (remote_port : Port) -> (recv_data : String) -> (data_len : Int) -> UDPRecvData
MkUDPAddrInfo : (remote_addr : SocketAddress) -> (remote_port : Port) -> UDPAddrInfo
MkSocket : (descriptor : SocketDescriptor) -> (family : SocketFamily) -> (socketType : SocketType) -> (protocolNumber : ProtocolNumber) -> Socket
EAGAIN : Int
ByteLength : Type
BACKLOG : Int

  Backlog used within listen() call -- number of incoming calls
