Following an interview question that was extremely hard I went to `man lstat’ and tried to code up a test just based on system documentation. It was not entirely successful, however after a tip-off from an online resource I came up with this.

File: lstat.c

#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <stdio.h></p>

int main(int c, char** argv) {
        struct stat buf;
        printf("%s is %d bytes\n", argv[1],buf.st_size);

        return 0;

When compile like this: g++ -o lstat lstat.c

It looks like this where yep.txt is a dummy file. `user@box ~/c $ ls -l /tmp/yep.txt ls -l /tmp/yep.txt -rw-r–r– 1 user users 17 Apr 9 23:16 /tmp/yep.txt

user@box ~/c $ ./lstat /tmp/yep.txt /tmp/yep.txt is 17 bytes`

So all this does is really use stat since yep.txt is a file and not a symbolic link. This stupid test just prints out the file size which you can see by the real `ls’ above.
