36<h3>DESCRIPTION</h3>
37<p>
38A <strong>do_mach_notify_port_deleted</strong> function is called by
39<strong>notify_server</strong> as the
40result of a kernel message indicating that a port name is no
41longer usable (that is,
42it no longer names a valid right), typically as a result of the right so named
43being consumed or moved. In contrast, a dead-name notification
44indicates that the
45port name is now dead as the result of the associated receive
46right having died.
47<var>notify</var> is the port named via <strong>mach_port_request_notification</strong>
48or <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.
