List of and documentation for system calls for XNU kernel in OSX

I'm trying to figure out how to get a list of and documentation for the system calls available in the XNU kernel in OSX. I've go开发者_运维技巧ogled around quite a bit, but haven't been able to find anything of use. As I understand the calling conventions match BSD, is that correct?

Thanks

The "official" list is at Darwin page at Apple. Specifically, see the file syscalls.master in the XNU distribution. (If something you expect is missing, try a newer XNU version.)

The BSD part of the system calls comes from BSD, but there're mach calls which follow quite different conventions.

You'll definitely want to read Amit Singh's OS X kernel book, see the book's website. It's rewritten for 10.4 and mainly for PPC, but still is the greatest detailed info you can get on the kernel.
