重叠I/O模型写的一个CNet类

类头如下：

class CNet

{

public:

static BOOL Close(SOCKET &socket);

static BOOL Close(TSOCKET &ts);

static int Receive(TSOCKET &socket , LPVOID lpData, DWORD dwSize , DWORD dwTimeout = INFINITE);

static int Send(TSOCKET &socket, LPVOID lpData, DWORD dwSize, DWORD dwTimeOut = INFINITE);

static BOOL StartUp();

static bool StartListen(TSOCKET &ts , short sListenPort);

CNet();

virtual ~CNet();

static int Connect(TSOCKET &ts , LPSTR lpServerAddr, short sPort);

static int Connect(TSOCKET &ts , LPSTR lpServerAddr, short sPort , STRUCT_PROXY &ProxyInfo);

static BOOL SetSocketOpt(SOCKET &s , int iBuffSize = BUFFERSIZE);

static int SendEx(SOCKET &socket, WSABUF **buf, DWORD dwBufCount, DWORD dwTimeOut);

static int ReceiveEx(SOCKET &socket , WSABUF **buf, DWORD dwBufCount , DWORD dwTimeout);

};
