    Hi,

    I want to write some C code to get a count of the number of
    CPU's on a running system.

    What is the difference between these two sysctls?

    kern.smp.cpus: Number of CPUs online
    hw.ncpu: Number of active CPUs

    Also, can someone give a brief description of these sysctls (sysctl -d
    doesn't show anything for them).

    Would it be a good idea to add some text to these syctls?

    kern.ccpu:
    hw.acpi.cpu.cx_history:
    machdep.hlt_cpus:
