The buffer trigger happens on a separate thread. I would like to do this without polling. I have tried select() but it does not seem to see new data from iio_push_to_buffers. Hi Dennis, What's wrong with just a read(), which will block until data is available? You can put it in it's own thread if you have other stuff to do. select() will work, it's a little more complex to setup correctly, and isn't really needed unless you are waiting on multiple fd's -Paul
