这是一个代理程序
void* hThread = CreateThread(NULL, 0, TCPProxyThread,se, 0, &idthread);
        if (hThread == NULL)
        {
            cout<<"CreateThread() Error!"<<endl;
            return;
        }
为什么调用TCPProxyThread时参数se的内容就改变了，原先地址中有有效数据，而传过去之后就全部清零了？哪位大侠帮忙看看，有源程序，谢谢！
DWORD WINAPI TCPProxyThread(LPVOID param)
{
    ServiceStruct* psvc = (ServiceStruct*)param;
    DWORD id1,id2;
    void* hThread1 = CreateThread(NULL, 0, TCPClientToServer,psvc, 0, &id1);
    if (hThread1 == NULL)
    {
        cout<<"CreateThread() Error!"<<endl;
        return 1;
    }
    void* hThread2 = CreateThread(NULL, 0, TCPServerToClient, psvc, 0, &id2);
    if (hThread2 == NULL)
    {
        cout<<"CreateThread() Error!"<<endl; 
        return 1;
    }
    SuspendThread(GetCurrentThread());
    return 0;
}
DWORD WINAPI TCPServerToClient(LPVOID param) //server to client
{
    ServiceStruct* psvc = (ServiceStruct*)param;
    char buf[1024];
    int count;
    while (true)
    {
        count = recv(psvc->svctcp_server,buf,1024,0);
        SendBuffer(psvc->tcpsock,buf,count);
        int i;
        cin>>i;
        cout<<"TCPServerToClient:server "<<psvc->svctcp_server<<endl;
        cout<<"TCPServerToClient:client "<<psvc->tcpsock<<endl;
    }
}
DWORD WINAPI TCPClientToServer(LPVOID param) //client to server
{
    ServiceStruct* psvc = (ServiceStruct*)param;
    char buf[1024];
    int count;
    while (true)
    {
        count = recv(psvc->tcpsock,buf,1024,0);
        SendBuffer(psvc->svctcp_server,buf,count);
        int i;
        cin>>i;
        cout<<"TCPClientToServer:server "<<psvc->svctcp_server<<endl;
        cout<<"TCPClientToServer:client "<<psvc->tcpsock<<endl;
    }
