[Question] how to get underlying file descriptors

alsa-project/alsa-lib issue #399 was opened from pfeatherstone:

I would like to use Alsa with the asio c++ library. I think all I need is the underlying file descriptor(s) for the device which I can then pass to Asio for polling and do all my asyncio. At the moment you're forced to use pollfd using snd_pcm_poll_descriptors(). Can I just read the fds or are there subtleties? Cheers
