OSX documentation for mknod

Question

I thought the documentation over at Apple was a little sparse on major/minor numbers for mknod. I was trying to create a raw character device for the microphone so that I could pipe data into it. On a proper linux system the kernel's ./Documentation/Devices.txt file contains the referenced major/minor numbers. Has Apple created any corollary documentation for creating raw kernel character devices for hardware access?

ex.: mknod dsp c 14 3

Thanks in advance.

hmm, why would you want to pipe data to the microfone node? – ktolis Nov 05 '12 at 22:53 — ktolis, Nov 05 '12 at 22:53

OS X is not Linux-based. On OS X many hardware devices are not accessed through traditional Unix device nodes which is why there is no documentation for making a microphone raw device. OS X provides rich support for audio devices through its Core Audio framework. See the Core Audio Overview manual for more information on how to get started.
