  38 <h3>DESCRIPTION</h3>
  39 <p>
  40 A <strong>default_pager_info</strong> function is called as the result
  41 of a message requesting
  42 that the default memory manager return information concerning the default
  43 pager's paging partitions.  The kernel does not make this call
  44 itself (which is why it
  45 can be a synchronous call); this request is only issued by (privileged) tasks
  46 holding the default memory manager port.
  47 <h3>RETURN VALUES</h3>
