If possible (supported bu OS) hb_secondsCPU() returns number CPU cycles consumed by programs not real time clock. It means that d = hb_secondsCPU(); Sleep( 10 ); d = hb_secondsCPU() - d; should give value close to 0.0 because inside Sleep( 10 ) process is suspended by OS and do not consume CPU at all. I think that we should add new function to extract real time clock with high precision. Because precision can be different on different OS-es then we will have to chose holder which allow to set different precision. We can use 2 integer numbers for that or single double number (floating point number are internally divided to mantissa and exponent what gives us the functionality we are looking for) Mindaugas used double value in his example and it's reasonable for me. The return value from such function can be used only to measure some real time differences because in portable programs it's undefined, i.e. in Mindaugas'es code it's the time of 1-st call to this function. I'll add such function ASAP. best regards, Przemek _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
