WIN网络编程-winsock库的管理类

 1、在每次编写网络程序时必须编写代码载入和释放Winsock库，可定义一个类来管理。(VC实现)

2、代码

#include <winsock2.h>

#pragma comment(lib,"WS2_32")

class CInitSock

{

public:

  CInitSock(BYTE minorVer=2,BYTEmajorVer=2)

  {

    WSADATAwsaData;

    WORDsockVersion=MAKEWORD(minorVer,majorVer);

    if(::WSAStartup(sockVersion,&wsaData))!=0

    {exit(0);}

  }

  ~CInitSock()

 {::WSACleanup();}  

};
