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;
}
