hi all
i'm using the the times() and clock() functions and i'm a little
confused:

struct tms tops;
clock_t tact;

tact = times(&tops);
printf("%g\n",(double)clock()/CLOCKS_PER_SEC);
printf("%g\n",(double)tact/CLOCKS_PER_SEC);
printf("%g\n",(double)tops.tms_utime/CLOCKS_PER_SEC);
printf("%g\n",(double)tops.tms_stime/CLOCKS_PER_SEC);

and i get the following:

6.79
9.6803
0.000675
4e-06

it is not suposed the return values of times() and clock are the same?
what are the units of tms_utime and tms_stime?
( tms_utime*10000 + tms_stime*10000 = cloc() ?)

thanks
