<strong>Function</strong> - Handle kernel operation request targeted for the default pager.
<h3>SYNOPSIS</h3>
<pre>
<strong>boolean_t	seqnos_memory_object_default_server</strong>
		<strong>(mach_msg_header_t</strong>	<var>request_msg</var>,
		<strong>mach_msg_header_t</strong>	<var>reply_ms</var><strong>);</strong>
</pre>
<h3>PARAMETERS</h3>
<dl>
<p>
<dt> <var>in_msg</var> 
<dd>
[pointer to in structure]
The memory manager message received from 
the kernel.
<p>
<dt> <var>out_msg</var> 
<dd>
[out structure]
A reply message.  Note that no kernel messages to a 
memory manager expect a direct reply.
</dl>
<h3>DESCRIPTION</h3>
<p>
The <strong>seqnos_memory_object_default_server</strong> function is
the MIG generated 
server handling function to handle messages from the kernel targeted to the
default memory manager.  This server function only handles messages unique to 
the default memory manager.  Messages that are common to all memory
managers are handled by <strong>seqnos_memory_object_server</strong>.
<p>
A \*Vmemory manager\*O
is a server task that responds to specific messages from the 
kernel in order to handle memory management functions for the kernel.  The
<strong>seqnos_memory_object_default_server</strong> function performs all necessary
argument handling for a kernel message and calls one of the default memory 
manager functions.
<h3>NOTES</h3>
<p>
<strong>seqnos_memory_object_default_server</strong> differs from
<strong>memory_object_default_server</strong> in that it supplies message
sequence numbers to the server
interfaces it calls.
<h3>RETURN VALUES</h3>
<dl>
<p>
<dt> <strong>TRUE</strong>
<dd>
The message was handled and the appropriate function was called.
<p>
<dt> <strong>FALSE</strong>
<dd>
The message did not apply to this memory management interface and 
no other action was taken.
