| Once you get past the above issues, the BSD functions to do file I/O from in-kernel code are pretty standard. Relevant functions include:

I think this is dead

| o NDINIT -- To initialise a struct nameidata from a path.
| o vn_open -- To open the file; this gives you back a vnode.
| o various vnode manipulation routines, for example, vn_lock, VOP_UNLOCK
| o vn_close
| o VOP_READ/VOP_WRITE -- To read and write data.

| S+E

these functions are from xnu/bsd/xxx directories, like NDINIT is in bsd/sys/namei.h while corresponding namei.h in /System/Library/Framework/Kernel.Framework/… is not so helpful.

How do I declare dependency for these in Info.plist?
