In the "Processor Time" node, times() is described with
The return value is the calling process' CPU time (the same value
you get from `clock()'.
But I think that's not the case on a Debian system. For instance,
#include <stdio.h>
#include <time.h>
#include <sys/times.h>
#include <unistd.h>
int
main (void)
{
struct tms t;
printf ("%ld %ld\n", times(&t), clock());
sleep(1);
printf ("%ld %ld\n", times(&t), clock());
return 0;
}
prints
430113019 10000
430113120 10000
times() has increased by 100 for the elapsed 1 second, but clock()
hasn't.
The way the code works corresponds to the posix specs, clock() is cpu
time consumed by the process, but the times() return is real time
(ie. wall clock).
