<h3>DESCRIPTION</h3>
<p>
The <strong>seqnos_notify_server</strong> function is the MIG generated server handling
function to handle messages from the kernel corresponding to IPC notifications. 
Such messages are delivered to the notification port named in a 
<strong>mach_msg</strong> or <strong>mach_port_request_notification</strong> call.  
The <strong>seqnos_notify_server</strong> function
performs all necessary argument handling for this kernel message and calls the
appropriate handling function.  These functions must be supplied by the caller.
<h3>NOTES</h3>
<p>
<strong>seqnos_notify_server</strong> differs from <strong>notify_server</strong>
in that it supplies message
sequence numbers to the server interfaces.
<h3>RETURN VALUES</h3>

<dt> <strong>TRUE</strong>
<dd>
The message was handled and the appropriate function was called.
<p>
<dt> <strong>FALSE</strong>

action was taken.
