Hi there! I'm a rookie on a mac. I've been trying to port some windows programs that was written in C/C++ onto the mac. I need to rewrite a timer that measures CPU ticks between the start and end of an operation. I wonder if there is something in the mac api similar as GetTickCount or GetTickCount64 ? You can use mach_absolute_time() (declared in mach/mach_time.h) for this purpose. For more information on using this routine, see this technical qa: http://developer.apple.com/qa/qa2004/qa1398.html Jason This email sent to site_archiver@lists.apple.com
