+<h3>PARAMETERS</h3>
+<dl>
+<p>
+<dt> <var>host_priv</var> 
+<dd>
+[in host-control send right]
+The control port naming the host for which 
+the default memory manager is to be set.
+<p>
+<dt> <var>default_manager</var> 
+<dd>
+[pointer to in/out default-pager send right]
+A memory manager port to 
+the new default memory manager.  If this value is <strong>MACH_PORT_NULL</strong>,

+<h3>DESCRIPTION</h3>
+<p>
+The <strong>host_default_memory_manager</strong> function establishes the default
+memory manager for a host.  The named manager will be the target for future
