LIBRARY
library “libkvm”
SYNOPSIS
#include
<sys/types.h>
#include <kvm.h>
int
kvm_getloadavg(kvm_t
*kd, double
loadavg[], int
nelem);
DESCRIPTION
Thekvm_getloadavg()
function returns the number of processes in the system run queue of the kernel
indicated by kd, averaged over various periods of time.
Up to nelem samples 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.
