title: how to determine which process is using a queue?
body: <p>I have a message queue id, i need to determine which processes are reading from and writing to that queue.
  Is there a possible option that can be used with 'ipcs'?</p>
  
  <pre><code>ipcs -q|grep qid 
  </code></pre>
  
  <p>this doesn't provide those details.
  Thanks</p>
