I'm trying to port some code from FreeBSD to OS X. The code is fairly low-level and it creates a number of special device files using make_dev() and controls functionality using functions like ioctl().
Ideally I'd like to keep my code as close to the original as possible so I can more easily merge upstream changes in the future: my question is, is there a way to create such device files on OS X? According to wikipedia the idiom is supported on the platform. Can someone point me in the right direction?
I think I've answered my own question: it seems the function to do this is devfs_make_node(). I can't find a man page but it is shown in some example code here.
