I have written a piece of code to get the kernel boot-time but it returns the error "No such file or directory". Where 
does it try to look this up from ? Couldn't find anything in the documentation.

While browsing for this, saw somewhere about a file called /kernel/boottime. My installation doesn't have a /kernel 
directory.

thanks
Sree.


#include <sys/time.h>
#include <sys/sysctl.h>
#include <errno.h>

int
main  (struct timeval *tv, struct timezone *tz)
{
  struct timeval boot = { 0, 0 };
  int mib[2] = {CTL_KERN, KERN_BOOTTIME};
  size_t size;

  size = sizeof (boot);

  if (sysctl (mib, 2, &boot, &size, NULL, 0) < 0)
     perror ("Boot time : ");
		
 return 0;
}
