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: -- Craig Rodrigues http://crodrigues.org rodrigc@crodrigues.org
