socket连接：

 

 1 lpszHost="127.0.0.1"
 2     nPort = 9200
 3     m_Socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); 
 4     
 5     if (m_Socket == SOCKET_ERROR)   
 6     { 
 7         return false;   
 8     }
 9 
10     // 构造sockaddr_in结构
11     sockaddr_in    ClientAddr;
12     ClientAddr.sin_family    = AF_INET;
13     ClientAddr.sin_port    = htons(nPort);
14     hostent* pHostent = gethostbyname((char*)lpszHost);
15     ClientAddr.sin_addr = *((struct in_addr *)pHostent->h_addr);
16     
17     if (connect(m_Socket, (SOCKADDR *)&ClientAddr, sizeof(ClientAddr)) == SOCKET_ERROR)   
18     {
19         return false;
20     }
21     m_bIsRunning = true;
22     m_hThread = CreateThread(NULL, 0, (LPTHREAD_START_ROUTINE)WorkThread, (LPVOID)this, 0, 0);
