getloadavg — get
system load averages
Standard C Library (libc, -lc)
#include
<stdlib.h>
int
getloadavg(double
loadavg[], int
nelem);
The
getloadavg()
function returns the number of processes in the system run queue 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.
If the load average was unobtainable, -1 is returned; otherwise, the number of samples actually retrieved is returned.
The getloadavg() function appeared in
4.3BSD-Reno.
