getloadavg — get system load averages
#define _BSD_SOURCE #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.
This page is part of release 2.79 of the Linux man-pages project. A
