Real time data input from hardware

P: 1
I'm working on a C++ app (in MS Visual C++ 6.0) to control a small test robot in a research lab to replace the existing LabView code (which I can't stand to look at).

I have functions to read the data from the encoders connected to the computer, and can output them when a button is pressed, but I'm wondering about the best way to take the data real time (and eventually dump it all to plain text files for MATLAB analysis).

I was thinking that just running a while loop until another button is pressed was a way, but I don't know how to make that not completely eat up all the CPU, and I also don't need it to run faster than 10kHz because that's the clock on the input board.

Thanks in advance!

Can you just pause between checks on the button?
