I need to bulk write/read through my IO Driver (kext). Can any one explain how to use IOMemoryDescriptor ? Any sample example that illustrates the very simple communication. It sounds like you might not be aware of the existence of the Apple Developer reference library. I highly recommend you start at <http:// developer.apple.com/referencelibrary> and use the search engine on those pages to find what you're looking for. The reference library includes developer documentation, technical notes, sample code, and technical Q&As. This information is also on your Mac OS X machine at /Developer/ADC Reference Library if you have the development tools installed. You might also want to review the mailing list guidelines at <http:// lists.apple.com>. Note particularly the statement "While Apple employees monitor the lists, Apple doesn't guarantee that questions will be answered. The mailing lists are not a replacement for formal support or bug reporting procedures." If you need help beyond what the documentation and sample code provides, you can also make use of Apple Developer Technical Support.

porting kernel sockets to Tiger

Darwin-kernel mailing list (Darwin-kernel(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-kernel/site_archiver%40lists.… Hi! I am porting an old sounddriver to the "new" Tiger KPI. Our driver takes the soundstream and sends it over the network to an soundserver, that will play it out for all clients. So the problem was the socket KPI which I ported already to get it korrekt syntax. Now there are errors I cannot point yet, stucking with the remote debugging process ;). Is there any knowledge base about porting network operations to the new KPI ? Perhaps I can reduce errors by porting it with a better list of known approaches for that topic.

Without knowing what your VFS kext does, specifically, it's hard to offer you much extra help. Typically you can expect an AV product to watch file operations that either affect the contents of files, or depend on their contents (open, execute, etc.). These intercepts will occur between the lookup operation and the corresponding access operation, and may result in secondary operations against the file. I was just trying to eliminate a possible cause of a bug. As it turned out the Norton installation on the machine in question was broken and not scanning files anyway. e.g. for an execute operation, you might expect to see a file looked up, then opened, read, closed, then executed. If you aren't keeping state dependent on VNOP call ordering, you should never know that something is snooping. This email sent to site_archiver(a)lists.apple.com

No announcement... this all comes from a blog that contains speculation not an official statement from Apple. We will have to wait an see what is taking place (note so far more -not less- source has been showing up for the intel branch). This email sent to site_archiver(a)lists.apple.com
