Example

variables
{
  TcpSocket gListenSocket;
  TcpSocket gConnectionSocket;
  char gRxBuffer[1000];
}

on start
{
  gListenSocket = TcpSocket::Open( IP_Endpoint(0.0.0.0:40004) );

  gListenSocket.Listen();
}

OnTcpListen( TcpSocket socket, long result)
{
  if (result == 0)
  {
    gConnectionSocket = TcpSocket::Accept( gListenSocket );

    {
      IP_Endpoint localEndpoint;
      IP_Endpoint remoteEndpoint;
      char localAddrStr[100];
      char remoteAddrStr[100];

      gConnectionSocket.GetSocketName( localEndpoint );
      gConnectionSocket.GetRemoteEndpoint( remoteEndpoint );

      localEndpoint.PrintEndpointToString( localAddrStr );
      remoteEndpoint.PrintEndpointToString( remoteAddrStr );
      write( "Accepted local %s, remote %s", localAddrStr, remoteAddrStr );
    }

    gConnectionSocket.Receive( gRxBuffer, elcount( gRxBuffer) );
  }
