title: why is there no poll/select like mechanism for message queue?
body: <p>Like we can do, poll/epoll/select on an fd, we can not on msg queue id. I found some non standard methods to make msgqueue-id to fd, but afterall its a non standard. So my question is, Why linux geeks, not implemented poll/select on msg queue id ? Does that lead to serious issue ?</p>
  
  <p>I need to implement such sort of mechanism. How can I do that ?</p>
