getloadavg - get system load averages
int getloadavg(double loadavg, int nelem);
Since glibc 2.19:
In glibc up to and including 2.19:
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 function is available in glibc since version 2.2.
For an explanation of the terms used in this section, see attributes(7).
