Network Programming for Windows读书笔记7

    套接字模式分为锁定模式和非锁定模式

      锁定模式示例如下:

    SOCKET sock;

    char buff[256];

     int done=0;

     while(!done)

     {

           nBytes=recv(sock,buff,65);

           if(nBytes==SOCKET_ERROR)

    {

            printf("recv failed with error %d/n",WSAGetLastError());

             Return;

     }

      DoComputationOnData(buff);

 }
