The -xml flag will insulate you against format changes, and is designed for machine parsing. Well, I took a different road. I don't want to rely on system_profiler for additional reasons (one of them is the fact that the -xml SPHardwareDataType does not work on Mac OS X 10.2, another one could be not to use a tank (slow and too much information) to kill an ant). For PowerPC, I still use the old code if the OS is too old. For i386, I use sysctl with the machdep.cpu branch and another one to get the family and to know whether it's a multi-core or mono-core CPUs. This email sent to site_archiver(a)lists.apple.com

BTW, there might be a bug/regression in sysctl on Mac OS X 10.4 (i386 and PPC). When you run sysctl hw, you get some information twice. On Panther, you don't observe this phenomenon.

A long time ago, I was using the mach APIs and host_processor_info to get the cpu type and subtype. I'm afraid this does not return good results on Intel Mac. On an iMac Core Duo, the subtype is said to be 4 and it does not match any reasonable value in machine.h. I had a look at some IOKit source code that gets this info by looking at the cpu device_type but this has changed on Intel Mac. The "cpu" type does not exist anymore and the "processor" type does not return any valuable information at all for me. I had a quick look at the sample code on the ADC website and it's using the Gestalt API and the constants in Carbon don't seem to be up- to-date. I looked at the sysctl hw.cpufamily which is highlighted in mach/ machine.h (on Intel Mac only AFAIK) but I have some troubles with this: This email sent to site_archiver(a)lists.apple.com

suspicious tab-completion crashes (recent)
by David Fang 27 Feb '07

site_archiver(a)lists.apple.com Delivered-To: darwin-dev(a)lists.apple.com Hi, Not sure if this is the right place to raise the issue, please suggest a different forum if this isn't the right place. I'm finding that after a recent software update for OS X 10.4.8 (powerpc G4), that tab-completion is causing out-of-memory frequently and non-determinstically, making it difficult to reproduce. This occurs in /bin/tcsh frequently, for example, just navigating around the directories. I became really suspicious when my console programs that link against libreadline (libedit.dylib) crashed similarly. I took a look at the list of libraries in /usr/lib that were modified by the recent update, and found /usr/lib/libedit.2.dylib and /usr/lib/libncurses.5.4.dylib (among many others). Have there been any recent modifications to either of these libraries (or their relatives) that could conceiveably caused this? Has anyone else (powerpc and/or command-line users, especially) been affected by this? I've filed a bugreport to Apple about my suspicious: radr:5025125 David "feels a disturbance in the source" Fang Computer Systems Laboratory Electrical & Computer Engineering Cornell University http://www.csl.cornell.edu/~fang/ -- (2400 baud?
