1.在通信的时候确保R0层的拷贝缓冲区大小等于R3层接收的缓冲区大小

2.在R3使用通信的时候，in 和 out缓冲区都填上，防止错误

    DWORD retlen = NULL;
    PPROCESS_INFOR pprocess = (PPROCESS_INFOR)malloc(500 * sizeof(PROCESS_INFOR));
    DeviceIoControl(hDevice, CTL_GET, pprocess, 500 * sizeof(PROCESS_INFOR), pprocess, 500 * sizeof(PROCESS_INFOR),&retlen ,NULL);
