activecpu is the correct name; the manifest constant name was not
changed because people have existing code that has to compile vs.
the MIB version of the call.
Okay, I'll use that then.
The preferred method for all sysctls going forward is to use
sysctlbyname(), so that's what you should use in new code.
I did wonder about that. All of the examples I've seen on this list
have been of the sysctlbyname() type.
Is there a list of the sysctls that are guaranteed to exist on all
machines (or by architecture). Also, a description of them would be
nice. For example, on this computer sysctl -a|grep cpu gives me (among
others):
It isn't clear to me how ncpu and activecpu relate to the others. My
guess is that ncpu is the same as logicalcpu_max and activecpu is the
same as logicalcpu. I'm not at my G5 so I can't check my assumptions
at the moment. The comments in the header do not mention physical/
logical for either ncpu or activecpu.
