How can I map the output given by time(2) and times(2) in system V? Can it be done? For e.g. if I do this; time1=time() sleep 2 time2=time() then time2-time1 is exactly 2 secs. But if I do this; time1=times() sleep 2 time2=times() then time2-time1 is about 160 (in clock ticks/sec) HZ=100. 1. Why are they different? 2. How can they be mapped as a function of each other? i.e how can I use time() alone to get the value given by times()? 3. Specifically, SUN's BSD version supports times(), but does not return anything except the status code unlike system V which actually returns elapsed real time. How do I use time() for this on a SUNserver? Thanks. -Manish Sharma 201-949-0094 (att,ulysses)!holin!mks
