title: How to prevent LD_PRELOAD on a binary?
body: <p>I write binary in C code.  How can I prevent another user from using <code>LD_PRELOAD</code> on my binary?</p>
  
  <p>When using <code>LD_PRELOAD</code>, is there any signal that I can handle and break the program?</p>
  
  <p>If I compile the binary statically, I heard that <code>LD_PRELOAD</code> will not work, right?</p>
  
  <p>Is there another way?</p>
