Re: sysctlbyname( "hw.availcpu" ) fails

Is Gestalt failing to give you the info you need in some way?

No, not at all. I thought that using Gestalt was discouraged in some way.

Not as far as I know. It's still fully supported and will be available in 64-bit Leopard too. If what you have is already working, I think you should just continue to use it.


Parts of it have been deprecated such as NewGestalt and ReplaceGestalt.

That is true; those particular APIs were rarely used and didn't really make sense to continue recommending.


Then there are other indications like <http://developer.apple.com/samplecode/CPUGestalt/index.html > which has an interesting warning.

I think that's mostly because we never recommend that you use the specific CPU type to make decisions about code paths. It doesn't matter whether you're getting the cputype from Gestalt or sysctlbyname, it's still better to use CPU capabilities rather than CPU types.
