跨平台---tcpclient與tcpserver

1、tcpclient(Linux)

1                         SocketAddress sa("192.168.20.43", 7000);
2                         StreamSocket ss(sa);
3                         int n = ss.sendBytes("hello", 5);
4                         char buffer[256];
5                         n = ss.receiveBytes(buffer, sizeof(buffer));
6                         printf("n = %d\n",n);      

2、tcpserver(win7)

TCPServer.cpp

1 #include "stdafx.h"
 2 #include <Poco/Net/TCPServer.h>
 3 #include <Poco/Net/TCPServerConnection.h>
 4 #include <Poco/Net/TCPServerConnectionFactory.h>
 5 #include <Poco/Util/Application.h>
 6 #include <Poco/Util/ServerApplication.h>

 8 using namespace Poco::Util;
