| 4 | <strong>Server Interface</strong> - Handle the current instance of a port-deleted notification. | |

| 7 | <strong>kern_return_t do_mach_notify_port_deleted</strong> | |
| 8 | <strong>(notify_port_t</strong> <var>notify</var>, | |
| 9 | <strong>mach_port_name_t</strong> <var>name</var><strong>);</strong> | |

| 12 | <strong>kern_return_t do_seqnos_mach_notify_port_deleted</strong> | |
| 13 | <strong>(notify_port_t</strong> <var>notify</var>, | |
| 14 | <strong>mach_port_seqno_t</strong> <var>seqno</var>, | |
| 15 | <strong>mach_port_name_t</strong> <var>name</var><strong>);</strong> | |

| 17 | <h3>PARAMETERS</h3> | |
| 18 | <dl> | |
| 19 | <p> | |
| 20 | <dt> <var>notify</var> | |
| 21 | <dd> | |
| 22 | [in notify (receive) right] | |
| 23 | The port to which the notification was sent. | |
| 24 | <p> | |
| 25 | <dt> <var>seqno</var> | |
| 26 | <dd> | |
| 27 | [in scalar] | |
| 28 | The sequence number of this message relative to the | |
| 29 | notification port. | |
| 30 | <p> | |
| 31 | <dt> <var>name</var> | |
| 32 | <dd> | |
| 33 | [in scalar] | |
| 34 | The invalid name. | |
| 35 | </dl> | |
| 36 | <h3>DESCRIPTION</h3> | |
| 37 | <p> | |
| 38 | A <strong>do_mach_notify_port_deleted</strong> function is called by | |
| 39 | <strong>notify_server</strong> as the | |
| 40 | result of a kernel message indicating that a port name is no | |
| 41 | longer usable (that is, | |
| 42 | it no longer names a valid right), typically as a result of the right so named | |
| 43 | being consumed or moved. In contrast, a dead-name notification | |
| 44 | indicates that the | |
| 45 | port name is now dead as the result of the associated receive | |
| 46 | right having died. | |
| 47 | <var>notify</var> is the port named via <strong>mach_port_request_notification</strong> | |
| 48 | or <strong>mach_msg</strong>. | |
| 49 | <h3>NOTES</h3> | |
| 50 | <p> | |
| 51 | This interface is machine word length specific because of the port name | |
| 52 | parameter. | |
| 53 | <h3>RETURN VALUES</h3> | |
| 54 | <p> | |
| 55 | Only generic errors apply. | |
