-//! \file socket.c
-//! \brief SOCKET APIs Implements file.
-//! \details SOCKET APIs like as Berkeley Socket APIs. 
-//! \version 1.0.3
-//! \date 2013/10/21
-//! \par  Revision history
-//!       <2014/05/01> V1.0.3. Refer to M20140501
-//!         1. Implicit type casting -> Explicit type casting.
-//!         2. replace 0x01 with PACK_REMAINED in recvfrom()
-//!         3. Validation a destination ip in connect() & sendto(): 
-//!            It occurs a fatal error on converting unint32 address if uint8* addr parameter is not aligned by 4byte address.
-//!            Copy 4 byte addr value into temporary uint32 variable and then compares it.
-//!       <2013/12/20> V1.0.2 Refer to M20131220
-//!                    Remove Warning.
-//!       <2013/11/04> V1.0.1 2nd Release. Refer to "20131104".
-//!                    In sendto(), Add to clear timeout interrupt status (Sn_IR_TIMEOUT)

- * @defgroup WIZnet_socket_APIs 1. WIZnet socket APIs
- * @brief WIZnet socket APIs are based on Berkeley socket APIs,  thus it has much similar name and interface.
- *        But there is a little bit of difference.
- * @details
- * <b> Comparison between WIZnet and Berkeley SOCKET APIs </b>
- * <table>
- *    <tr>   <td><b>API</b></td> <td><b>WIZnet</b></td> <td><b>Berkeley</b></td>   </tr>
- *    <tr>   <td>socket()</td> <td>O</td> <td>O</td>   </tr>
- *    <tr>   <td><b>bind()</b></td> <td>X</td> <td>O</td>   </tr>
- *    <tr>   <td><b>listen()</b></td> <td>O</td> <td>O</td>   </tr>
- *    <tr>   <td><b>connect()</b></td> <td>O</td> <td>O</td>   </tr>
- *    <tr>   <td><b>accept()</b></td> <td>X</td> <td>O</td>   </tr>
- *    <tr>   <td><b>recv()</b></td> <td>O</td> <td>O</td>    </tr>
- *    <tr>   <td><b>send()</b></td> <td>O</td> <td>O</td>   </tr>
- *    <tr>   <td><b>recvfrom()</b></td> <td>O</td> <td>O</td>   </tr>
- *    <tr>   <td><b>sendto()</b></td> <td>O</td> <td>O</td>    </tr>
- *    <tr>   <td><b>closesocket()</b></td> <td>O<br>close() & disconnect()</td> <td>O</td>   </tr>
- * </table>
- * There are @b bind() and @b accept() functions in @b Berkeley SOCKET API but,
- * not in @b WIZnet SOCKET API. Because socket() of WIZnet is not only creating a SOCKET but also binding a local port number,
- * and listen() of WIZnet is not only listening to connection request from client but also accepting the connection request. \n
- * When you program "TCP SERVER" with Berkeley SOCKET API, you can use only one listen port.
- * When the listen SOCKET accepts a connection request from a client, it keeps listening.
- * After accepting the connection request, a new SOCKET is created and the new SOCKET is used in communication with the client. \n
- * Following figure shows network flow diagram by Berkeley SOCKET API.
- * @image html Berkeley_SOCKET.jpg "<Berkeley SOCKET API>"
- * But, When you program "TCP SERVER" with WIZnet SOCKET API, you can use as many as 8 listen SOCKET with same port number. \n
- * Because there's no accept() in WIZnet SOCKET APIs, when the listen SOCKET accepts a connection request from a client,
- * it is changed in order to communicate with the client.
- * And the changed SOCKET is not listening any more and is dedicated for communicating with the client. \n
- * If there're many listen SOCKET with same listen port number and a client requests a connection,
- * the SOCKET which has the smallest SOCKET number accepts the request and is changed as communication SOCKET. \n
- * Following figure shows network flow diagram by WIZnet SOCKET API.
