Comment Comment by netbsdusers It's rather a bit more BSD than merely having a "C API that resembles BSD" or a "BSD userland".https://github.com/apple-oss-distributions/xnu/tree/main/bsdYou can find there the better part of a whole BSD kernel, including the fundamental datastructures like proc, tty, vnode, and user.The point of departure is 4.4BSD-Lite2. The majority of the core of the BSD kernel carries the relevant notices for that. parent netbsdusers 8 months ago
