|Write a buffer over the socket connection. Returns the number of bytes written or -1 if an error occurs. |

|Read a buffer from the socket connection, up to length bufferSize. Returns the number of bytes read or -1 if an error occurs. |

STK TCP socket server class.
This class provides a uniform cross-platform TCP socket server interface. Methods are provided for reading or writing data buffers to/from connections.
TCP sockets are reliable and connection-oriented. A TCP socket server must accept a connection from a TCP client before data can be sent or received. Data delivery is guaranteed in order, without loss, error, or duplication. That said, TCP transmissions tend to be slower than those using the UDP protocol and data sent with multiple write() calls can be arbitrarily combined by the underlying system.
The user is responsible for checking the values returned by the read/write methods. Values less than or equal to zero indicate a closed or lost connection or the occurence of an error.

|stk::TcpServer::TcpServer||(||int||port = ||)|
Default constructor creates a local socket server on port 2006 (or the specified port number).
An StkError will be thrown if a socket error occurs during instantiation.
Extract the first pending connection request from the queue and create a new connection, returning the descriptor for the accepted socket.
If no connection requests are pending and the socket has not been set non-blocking, this function will block until a connection is present. If an error occurs, -1 is returned.
