Memory usage of current process in C

Question

I need to get the memory usage of the current process in C. Can someone offer a code sample of how to do this on a Linux platform?

I\'m aware of the cat /proc/

I came across this post: http://appcrawler.com/wordpress/2013/05/13/simple-example-of-tracking-memory-using-getrusage/

Simplified version:

#include 
#include 

int main() {
  struct rusage r_usage;
  getrusage(RUSAGE_SELF,&r_usage);
  // Print the maximum resident set size used (in kilobytes).
  printf("Memory usage: %ld kilobytes\n",r_usage.ru_maxrss);
  return 0;
}

(tested in Linux 3.13)
