6 .TH GETLOADAVG 3C "Jun 28, 2004"
8 getloadavg \- get system load averages
12 #include <sys/loadavg.h>
14 \fBint\fR \fBgetloadavg\fR(\fBdouble\fR \fIloadavg\fR[\|], \fBint\fR \fInelem\fR);
20 The \fBgetloadavg()\fR function returns the number of processes in the system
21 run queue averaged over various periods of time. Up to \fInelem\fR samples are
22 retrieved and assigned to successive elements of \fIloadavg\fR[\|]. The system
23 imposes a maximum of 3 samples, representing averages over the last 1, 5, and
24 15 minutes, respectively. The \fBLOADAVG_1MIN\fR, \fBLOADAVG_5MIN\fR, and
25 \fBLOADAVG_15MIN\fR indices, defined in <\fBsys/loadavg.h\fR>, can be used to
26 extract the data from the appropriate element of the \fIloadavg\fR\fB[\|]\fR
31 Upon successful completion, the number of samples actually retrieved is
32 returned. If the load average was unobtainable, \fB\(mi1\fR is returned and
33 \fBerrno\fR is set to indicate the error.
37 The \fBgetloadavg()\fR function will fail if:
44 The number of elements specified is less than 0.
50 If the caller is in a non-global zone and the pools facility is active, the
51 behavior of \fBgetloadavg()\fR is equivalent to that of
52 \fBpset_getloadavg\fR(3C) called with \fIpsetid\fR set to \fBPS_MYID\fR.
