Server-interface routine of the iocompressionstats_notification MIG subsystem (subsystem id 5600), implemented by a user-space statistics daemon. The kernel sends this one-way message on the registered iocompressionstats port (bsd/vfs/vfs_io_compression_stats.c) when the I/O compression statistics buffer is ready to be collected; flags is currently sent as 0.

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