<h2>do_mach_notify_dead_name</h2>

<strong>Server Interface</strong> - Handle the current instance of a dead-name notification.

<h3>SYNOPSIS</h3>

<strong>kern_return_t do_mach_notify_dead_name</strong>

<strong>(notify_port_t</strong> <var>notify</var>,

<strong>mach_port_name_t</strong> <var>name</var><strong>);</strong>

<strong>kern_return_t do_seqnos_mach_notify_dead_name</strong>

<strong>(notify_port_t</strong> <var>notify</var>,

<strong>mach_port_seqno_t</strong> <var>seqno</var>,

<strong>mach_port_name_t</strong> <var>name</var><strong>);</strong>

<h3>PARAMETERS</h3>

<dt> <var>notify</var>

[in notify (receive) right]

The port to which the notification was sent.

<dt> <var>seqno</var>

[in scalar]

The sequence number of this message relative to the

notification port.

<dt> <var>name</var>

[in scalar]

The dead name.

<h3>DESCRIPTION</h3>

A <strong>do_mach_notify_dead_name</strong> function is called by <strong>notify_server</strong>

as the

result of a kernel message indicating that the port name is now

dead as the result

of the associated receive right having died. In contrast, a port-deleted

notification indicates that the port name is no longer usable

(that is, it no longer names

a valid right), typically as a result of the right so named being consumed or

moved. <var>notify</var> is the port named via <strong>mach_port_request_notification</strong>

or

<strong>mach_msg</strong>.

<h3>NOTES</h3>

This interface is machine word length specific because of the port name

parameter.

<h3>RETURN VALUES</h3>

Only generic errors apply.
