| <p>A send-once notification is generated when a send-once right is destroyed without being used.</p> |
| <p>This behaves equivalently to a <code>do_mach_notify_send_once()</code> function used with <code>notify_server()</code>.</p> |

| <dl class="section note"><dt>Note</dt><dd>Unlike the other notifications in the <code>notify</code> subsystem, send-once notifications are not generated as a result of a notification request, but are generated any time a send-once right is destroyed rather than being used. The notification is sent via the send-once right to its receiver. These notifications are more useful for clients, not servers. Send-once notifications are normally handled by MIG-generated client routines, which make send-once rights for their reply ports and interpret send-once notifications as a signal that there will be no reply. Although not expected to be primarily useful for servers, this method is provided because send-once notifications are defined as a part of the <code>notify</code> subsystem. </dd></dl> |
