title: Is it safe to pass a null pointer to ippsFree?
body: <p><a href="https://software.intel.com/en-us/node/502012" rel="nofollow">Intel Document</a> only describes ptr passed in should point the space allocated from ippsMalloc. It does not say anything what happened if we pass a null pointer in it. </p>
  
  <pre><code>void ippsFree(void* ptr);
  </code></pre>
  
  <blockquote>
    <p>ptr Pointer to a memory block to be freed. The memory block pointed to
    with ptr is allocated by the function ippsMalloc.</p>
  </blockquote>
  
  <p>Is it safe like free/delete accept null pointer? or is it undefined?</p>
