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