site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Organization: Rogue Research Hi all, The docs for IOObjectRelease() are terse. I'm wondering: 1) How does IOObjectRelease() react to being given null? Does it do nothing like free() or crash like CFRelease()? Yes, I could try, but I'm looking for an API guarantee one way or the other. 2) Is IOObjectRelease() threadsafe? Specifically, if I create some object on the main thread, is it safe to IOObjectRelease() it from an Objective-C garbage collector finalize method (which runs on its own thread)?
