43<h3>DESCRIPTION</h3>
44<p>
45The <strong>policy_fifo_info</strong> structure defines the first-in-first-out
46scheduling policy information.
47FIFO threads have two priorities associated with them by the system:
48<ul>
49  <p>
50<li>
51A maximum priority value which can be raised only via privileged operation 
52so that users may not unfairly compete with other users in their processor 
53set.  Newly created threads obtain their maximum priority from that of their 
54assigned processor set.
55     <p>
56<li>
57A priority value which can be set by the thread to any value up to a
58maximum priority.  Newly created threads obtain their priority from their task.
59</ul>
