This email sent to site_archiver@lists.apple.com I'm please to be a new member of darwin-dev so here is the first question :) I would like to retrieve the current cpu frequency of each cpu/core installed (this frequency can change depending on the use -thanks to the intel speedstep technology-). Does anyone know which system call should be use to do so? smime.p7s
