I exactly have the same problem, the main application updates a message queue, 
the client checks if the queue has any messages, and if there is, it 
dispatches them.

while (true)
{
  // semaphore
  sem_wait(&semdata)
  
   if (!message.empty())
       dispatch(message);

  sem_post(&semdata);
}

But the above looks like it's going to burn the CPU. Any ideas?
