Maybe you'd get some answers if you were asking your questions on the streaming-server-dev or streaming-server-users list instead of here, the Darwin (Operation System) Developers List. Despite common belief just "Darwin" is not an streaming server, the "Darwin Streaming Server" is ( See also: http://developer.apple.com/darwin/projects/darwin/faq.html , http://developer.apple.com/darwin/projects/streaming/ ). Find the appropiate lists here: I already proposed that there should be a - maybe boldface - note in http://lists.apple.com/mailman/listinfo/darwin-dev or the welcome message that those darwin lists don't cover streaming server topics. It's too often that people get caught in this trap. smime.p7s

This virtual volume should show up in finder like toast or dmg images and show up in /Volumes/ the application "says" what the contents of this device are. this virtual device should be read / write. if the application quits, the device is removed. if someone has sample code or documentation about this subject, i would be happy :-) if this is off-topic, then please excuse me and tell me which list is convenient for this question!

Darwin-dev mailing list (Darwin-dev(a)lists.apple.com) Help/Unsubscribe/Update your Subscription: http://lists.apple.com/mailman/options/darwin-dev/site_archiver%40lists.app… I am trying to get an unqualified name for the local host. To do this I loop over the addresses returned by getifaddrs(), select the first AF_INET, running, non-loopback address and call getnameinfo() with the NI_NAMEREQD and NI_NOFQDN flag set. I'm expecting the host name returned by getnameinfo() to be unqualified, but I am getting a fully qualified name as if NI_NOFQDN had not been set. I see this on 10.3.9 and 10.4.2. I've looked at the source at <http://www.opensource.apple.com/darwinsource/10.4.2/bind9-11/bind9/lib/lwre…> and that does take notice of the NI_NOFQDN flag. Am I looking at the right code? Am I mis-understanding what the NI_NOFQDN flag does? This email sent to site_archiver(a)lists.apple.com

Try not to free it but reuse the same buffer instead. Allocate it not with malloc, but with vm_allocate, then vm_wire it. This avoids paging and bypasses the global malloc lock. It also gives you a nice page-aligned buffer that you can then slice and dice any way you want (e.g. for cache coloring). This email sent to site_archiver(a)lists.apple.com
