#include <kvm.h> int
kvm_getloadavg (kvm_t *kd double loadavg[] int nelem);
DESCRIPTION
The
kvm_getloadavg ();
function returns the number of processes in the system run queue
of the kernel indicated by
Fa kd ,
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.
