getloadavg - get system load averages
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
The LOADAVG_1MIN, LOADAVG_5MIN, and LOADAVG_15MIN indices,
defined in <sys/loadavg.h>, can be used to extract the data
from the appropriate element of the loadavg array.
Upon successful completion, the number of samples actually
retrieved is returned. If the load average was unobtainable,
-1 is returned and errno is set to indicate the error.
The getloadavg() function will fail if:
The number of elements specified is less than 0.
