I start a thread to recive the data.
In the thread, there are 2 buffers. BufA and BufB. When one of them is full, the other one will collect the data.
I'll do this loop with WaitForXfer, FinishDataXfer，BeginDataXfer。
I found that, Once the FinishDataXfer fails, the data you received next time is not in buf, but in buf_next.
Is that possible?
