It would have been on this list or the Unix Porting list. If you can find that in the list archives, I'm sure it would answer all your questions about which to use where, when, and how they function. Hello, Jay. I think that mach_absolute_time function does have the best resolution available. I was also discussed in performance-optimization maillist and appeared that mach_absolute_time is the lowest-level recommended function.

Re: Query about the frameworks not available in iPhone SDKs but available in Mac OS X sdk.

Rewrite your code to stop using those frameworks, is probably the best advice. You can file a request with Apple, but who knows if/when they'll do anything about it? Porting over open-source framework sources is conceivable, but can easily turn into a huge amount of work if you can't get those sources to build or run on iPhone (which might be one reason they're not there to begin with...) Also, you mentioned you're building a dylib. Are you aware that iPhone apps can't contain embedded dylibs or frameworks? I'm not sure why, but this is an Apple requirement. You can build modules as static libraries and then link them into your app, though. This email sent to site_archiver(a)lists.apple.com
