getloadavg(3) Library Functions Manual getloadavg(3)
getloadavg - get system load averages
Standard C library (libc, -lc)
#include <stdlib.h>
int getloadavg(double loadavg[], int n);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
getloadavg():
Since glibc 2.19:
_DEFAULT_SOURCE
In glibc up to and including 2.19:
_BSD_SOURCE
The getloadavg() function returns the number of processes in the
system run queue averaged over various periods of time. Up to n
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.
For an explanation of the terms used in this section, see
attributes(7).
