So, to recap my understanding of all this: 1) It is possible to use stuff in /usr/include/libkern, but...

I just want to have a definitive answer before I start relying on something that goes away. This is not an official support channel, and none of us speak for Apple here, unless it's an announcement or a statement by DTS. Some of us maintain some of the code we've been talking about, and may have some influence on where it goes, but all we can really offer is our own opinions. 2) ...don't do that! It may/probably will go away at some point in the future as cleanup occurs. It's published. You are minimally going to be safe specifying a deployment target, e.g. 10.5, and using it for a good long while. If Dave and I have anything to say about it, it _will_ likely get moved or renamed. We can't do anything unilaterally, we are small cogs on larger teams, and there are other people whose opinions matter very much, frequently more than ours. 3) There isn't anything quite like the OSAtomic* operators in user space that are truly supported (that is, won't be removed in the future during cleanup), and therefore if I want shared variables, I need to use pthread_mutex_lock(), write my variable, and then unlock(). If it's currently documented, it's currently supported. Shawn already pointed you at the documentation. We don't really guarantee anything about future support, and I and the rest of us (Dave Z., Shawn, etc.) are prohibited by our employment contracts from making those kinds of statements. They are above our pay grade. If you need that kind of official statement, you need to file a bug to get it (or an official "no comment"). Being from a military lab, you are undoubtedly familiar with "chain of command". You are currently talking to S4s in a mess tent. 8-). -- Terry This email sent to site_archiver@lists.apple.com
