36<h3>DESCRIPTION</h3>
37<p>
38A <strong>do_mach_notify_dead_name</strong> function is called by <strong>notify_server</strong>
39as the
40result of a kernel message indicating that the port name is now
41dead as the result 
42of the associated receive right having died.  In contrast, a port-deleted
43notification indicates that the port name is no longer usable
44(that is, it no longer names 
45a valid right), typically as a result of the right so named being consumed or 
46moved. <var>notify</var> is the port named via <strong>mach_port_request_notification</strong>
47or 
48<strong>mach_msg</strong>.
49<h3>NOTES</h3>
50<p>
51This interface is machine word length specific because of the port name
52parameter.
53<h3>RETURN VALUES</h3>
54<p>
55Only generic errors apply.
