sysinfo()

I was reminded in an article about sysinfo() on Linux, also gave me a change to remind myself of some basic C programming principles, e.g. bitwise shifts.

#include <stdio.h>
#include <sys/sysinfo.h>

int main() {
   struct sysinfo info;
   float todivideby = 0.00;
   sysinfo(&info);
   printf("Uptime (s) = %ld\n",info.uptime);
   printf("SI_LOAD_SHIFT = %d\n", SI_LOAD_SHIFT);
   todivideby = 1<<SI_LOAD_SHIFT;
   //printf("divide by: %.2f\n", todivideby);
   printf("Load Averages %.2f,%.2f,%.2f\n",info.loads[0]/todivideby, info.loads[1]/todivideby, info.loads[2]/todivideby);
   printf("Totalram = %ld memory units\n",info.totalram);
   printf("Freeram = %ld memory units\n",info.freeram);
   printf("Memory used = %ld memory units\n", info.totalram - info.freeram);
   printf("Sharedram = %ld memory units\n",info.sharedram);
   printf("bufferram = %ld memory units\n",info.bufferram);
   printf("totalswap = %ld memory units\n",info.totalswap);
   printf("freeswap = %ld memory units\n",info.freeswap);
   printf("totalhigh = %ld memory units\n",info.totalhigh);
   printf("freehigh = %ld memory units\n",info.freehigh);
   printf("Memory unit = %d bytes\n", info.mem_unit);
   printf("Number of procs = %d\n", info.procs);
   return 0;
}
