vnode_lookup
Convert a path into a vnode.
Declaration
errno_t vnode_lookup(const char *path, int flags, vnode_t *vpp, vfs_context_t ctx);Parameters
- path:
Path to look up.
- flags:
VNODE_LOOKUP_NOFOLLOW: do not follow symbolic links. VNODE_LOOKUP_NOCROSSMOUNT: do not cross mount points.
Return Value
Results 0 for success or an error code.
Discussion
This routine is a thin wrapper around xnu-internal lookup routines; if successful, it returns with an iocount held on the resulting vnode which must be dropped with vnode_put().
