You should learn C a bit better.
In your program you don't actually call getloadvg(), you just declare
it inside your function. You also try to print doubles as integers.

Try this program instead:


#include <stdio.h>
#include <stdlib.h>

int main(void)
	{
	double avg[3];
	int i;
	
	getloadavg(avg,3);	
	for(i=0;i<3;i++)
		{
		printf("%f\n",avg[i]);
		}
	return 0;
	}
