Server-interface routine (ServerPrefix receive_) of the sysdiagnose_notification MIG subsystem (subsystem id 31337), implemented by the sysdiagnose daemon. The kernel sends the notification on the host sysdiagnose port when a sysdiagnose is triggered (e.g. by the diagnostic key chord); flags carries the triggering keycode. Superseded in the kernel's sender by the _with_audit_token variant (osfmk/kern/sysdiagnose.c).

Server-interface routine of the sysdiagnose_notification MIG subsystem, implemented by the sysdiagnose daemon. Variant of receive_sysdiagnose_notification whose message carries the sender's audit token, letting the daemon verify the notification came from the kernel. Sent by sysdiagnose_notify_user (osfmk/kern/sysdiagnose.c) with the triggering keycode in flags.

MIG-generated demultiplexer for the sysdiagnose_notification subsystem (osfmk/mach/sysdiagnose_notification.defs). If the request message at InHeadP belongs to the subsystem, calls the matching handler (receive_sysdiagnose_notification, receive_sysdiagnose_notification_with_audit_token), formats the reply message at OutHeadP, and returns TRUE; returns FALSE, with a MIG_BAD_ID error reply, for messages that do not belong to the subsystem.

Returns the MIG dispatch function for the sysdiagnose_notification subsystem request whose msgh_id is found in InHeadP, or a null pointer if the message is not a request of the subsystem. Alternative to the combined demultiplexer for servers that look up and invoke the handler themselves.
