------- Additional Comments From lionel.ulmer@free.fr 2004-25-01 12:13 ------- The question is how to emulate QueryPerformanceCounter and QueryPerformanceFrequency on Linux... Either we use 'gettimeofday' (and thus do a syscall each time the Win32 application calls this) or we use the 'rtdsc' instruction and need the CPU frequency.
So the real question would rather be : how does Windows do to implement the Performance functions for non-constant MHz CPUs.
