title: inotify_init() function not implemented ERROR
body: <p>I am working on a Linux based router, I wrote code using <code>inotify_init()</code> for monitoring a file. The cross compilation was done without a warning or error message, but when I try to execute that code it shows an error like <code>function not implemented</code></p>
  
  <pre><code> if ( (fp = inotify_init()) &lt; 0  ) {
      printf("something went wrong with inotify_init()! %s\n", strerror(errno));
      printf("#### 1 can't open file\n");
      goto err; //exit(0);
  }
  </code></pre>
