are retrieved and assigned to successive elements of loadavg[]. The system imposes a maximum of 3 samples, representing averages over the
last 1, 5, and 15 minutes, respectively.
DIAGNOSTICS
If the load average was unobtainable, -1 is returned; otherwise, the number of samples actually retrieved is returned.
