DAQmxGetReadAvailSampPerChan parameter

[jaehong0217]

For some reason I couldn't find a detail description of this function

DAQmxGetReadAvailSampPerChan, which takes task handles and data

I don't understand what the data parameter means, so I am confused what I should put it here.

Any one help me to understand this function??

What I am trying to do is

while let a NIDAQ board continuously record signals, I want to read predefined numbers of data so that I can process it later.

I think this function make sure the size of data I want to read for each loop.

If another approach would fit better to my purpose, please recommend me it.

Thanks

This function will return the available samples per channel currently buffered for each channel in the task.  This single number will be the same for each channel and will return as a uInt32 datatype.
