I am working in the context of a I/O Kit Driver. I am getting access to these file operations through the Kernel.Framework (to include vnode.h, namei.h, uio.h, ect..), which from what I can tell is running from the BSD portions of the kernel (I'm not really sure how correct I am about that). ----- Original Message ----- From: "Quinn" <eskimo1@apple.com> To: <darwin-kernel@lists.apple.com> Sent: Wednesday, April 09, 2003 9:44 AM Subject: Re: File Access with VFS

There isn't a single "kernel mode" on Mac OS X. The answer differs
depending on whether you're running within BSD portions of the kernel
(indeed, what part of BSD), within an I/O Kit driver, and so on.
What context is your code executing in?
