accept : (sock : Socket) -> IO (Either SocketError (Socket, SocketAddress))

  Accept a connection on the provided socket.

  Returns on failure a `SocketError`
  Returns on success a pairing of:

  - `Socket` :: The socket representing the connection.
  - `SocketAddress` :: The
  sock

    The socket used to establish connection.

bind : (sock : Socket) -> (addr : Maybe SocketAddress) -> (port : Port) -> IO Int

  Binds a socket to the given socket address and port.
  Returns 0 on success, an error code otherwise.

close : Socket -> IO ()

  Close a socket

connect : (sock : Socket) -> (addr : SocketAddress) -> (port : Port) -> IO ResultCode

  Connects to a given address and port.
  Returns 0 on success, and an error number on error.

listen : (sock : Socket) -> IO Int

  Listens on a bound socket.

  sock

    The socket to listen on.

recv : (sock : Socket) -> (len : ByteLength) -> IO (Either SocketError (String, ResultCode))

  Receive data on the specified socket.

  Returns on failure a `SocketError`
  Returns on success a pairing of:

  - `String` :: The payload.
  - `ResultCode` :: The result of the underlying function.
  sock

    The socket on which to receive the message.

  len

    How much of the data to receive.

recvAll : (sock : Socket) -> IO (Either SocketError String)

  Receive all the remaining data on the specified socket.

  Returns on failure a `SocketError`
  Returns on success the payload `String`

  sock

    The socket on which to receive the message.

recvFrom : (sock : Socket) -> (len : ByteLength) -> IO (Either SocketError (UDPAddrInfo, String, ResultCode))

  Receive a message.

  Returns on failure a `SocketError`.
  Returns on success a triple of

  - `UDPAddrInfo` :: The address of the sender.
  - `String` :: The payload.
  - `Int` :: Result value from underlying function.
  sock

    The channel on which to receive.

  len

    Size of the expected message.

send : (sock : Socket) -> (msg : String) -> IO (Either SocketError ResultCode)

  Send data on the specified socket.

  Returns on failure a `SocketError`.
  Returns on success the `ResultCode`.

  sock

    The socket on which to send the message.

  msg

    The data to send.

sendTo : (sock : Socket) -> (addr : SocketAddress) -> (port : Port) -> (msg : String) -> IO (Either SocketError ByteLength)

  Send a message.

  Returns on failure a `SocketError`
  Returns on success the `ResultCode`

  sock

    The socket on which to send the message.

  addr

    Address of the recipient.

  port

    The port on which to send the message.

  msg

    The message to send.

socket : (fam : SocketFamily) -> (ty : SocketType) -> (pnum : ProtocolNumber) -> IO (Either SocketError Socket)

  Creates a UNIX socket with the given family, socket type and protocol
  number. Returns either a socket or an error.
