Server-interface routine of the telemetry_notification MIG subsystem (subsystem id 5100), implemented by a user-space telemetry daemon. The kernel telemetry facility (osfmk/kern/telemetry.c) sends this one-way message on the host telemetry port when a telemetry buffer is ready to be harvested; flags is a telemetry_notice_t identifying the source (e.g. TELEMETRY_NOTICE_BASE for the microstackshot buffer).

MIG-generated demultiplexer for the telemetry_notification subsystem (osfmk/mach/telemetry_notification.defs). If the request message at InHeadP belongs to the subsystem, calls the matching handler (telemetry_notification), 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 telemetry_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.
