Example #2

// This test verifies that if an EOF arrives on a socket when there is a
// pending `recv()` call, the EOF will be correctly received.

  // Connect to the IP from the libprocess library, but use the port
  // from the `bind` call above. The libprocess IP will always report
  // a locally bindable IP, meaning it will also work for the server
  // socket above.
  //
  // NOTE: We do not use the server socket's address directly because
  // this contains a `0.0.0.0` IP. According to RFC1122, this is an
  // invalid address, except when used to resolve a host's address
  // for the first time.
  // See: https://tools.ietf.org/html/rfc1122#section-3.2.1.3

  // Make the final `recv()` call before the socket is shutdown.
  Future<string> receive = client->recv();
