PCI6713,WFM_DB_Transfer: How to determine which double-buffer is in progress

[Hiroyuki]

Hi, I am using PCI6713, double buffered mode programming by Visual C++.
While doing double buffer, I must reflesh data in real-time(within 4ms). and I don't know how to determine which buffer(first or last) is in progress.
Is there any function to know that? And at the same time, is there any function to control that?

Hello;

Unfortunately, there isn't a NI-DAQ function that allows one to monitor if the upper or lower part of the buffer is being updated at any given time.
