If you go to this length, just pass the file contents in, rather than the file descriptor number. Trying to convert from a filedescriptor number to real file data from within a KEXT will require you to access all sorts of kernel-private data structures which are not guaranteed against release-to-release changes.

I believe the vn driver is a good place to copy code from. _______________________________________________ darwin-kernel mailing list | darwin-kernel@lists.apple.com Help/Unsubscribe/Archives: http://www.lists.apple.com/mailman/listinfo/darwin-kernel Do not post admin requests to the list.
