#include <stdlib.h> int
getloadavg (double loadavg[] int nelem);
DESCRIPTION
The
getloadavg ();
function returns the number of processes in the system run queue
averaged over various periods of time.
Up to
Fa nelem
samples are retrieved and assigned to successive elements of
Fa loadavg Ns Bq .
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.
