... what you want to look at is:

/System/Library/Frameworks/Kernel.framework/Headers/sys/vnode.h

Specifically, the functions:

   vnode_open()
   vn_rdwr()
   vnode_close()

They have comments which describe how you use them.  You'll need a few other
functions as well (vfs_context_create(), vfs_context_rele(), vnode_get(),
vnode_put()).  Not documented wonderfully, but better than a lot of other
kernel stuff.
