Caveat emptor. If the vnode references a directory, you can just VOP_LOOKUP "..". This is, however, subject to vnode locking constraints. For files, I don't think there's a file system independent way. For Macintosh file systems (HFS, HFS Plus, AFP), you can probably doing this by: 1. using VOP_GETATTRLIST with ATTR_CMN_PAROBJID to get the parent's CNID and then 2. using volfs to get the vnode from the CNID. <http://developer.apple.com/qa/qa2001/qa1113.html> This second alternative is a significant binary compatibility liability. It's *definitely* not appropriate to put it in a product that you're going to ship to lots of users. OTOH, it's more compatible than going poking around in v_data.
