Mach messages: ledger
Message catalog and dispatch · All subsystem ranges · Kernel entry map
osfmk/mach/ledger.defs. Not listed as a separate subsystem in this checkout's mig_e table. Local bodies, generated interfaces and compatibility aliases are distinguished below; a declaration alone does not establish an active kernel message endpoint.
Registration evidence: mig_e.
Reading these entries
IDs are computed from the explicit preprocessing profiles in the catalog guide, counting both routines and skip slots. They are not discovered from a running kernel. Each entry retains all observed names/declaration locations; the displayed fields come from the first non-skipped profile. Alternative declarations can have different fields. simpleroutine is one-way at the MIG interface level.
An interface contract block quotes the adjacent local .defs comment with whitespace normalized. Mechanism paragraphs explain selected implementation decisions. Local body links and call names identify implementation evidence; syntactic call lists are reading aids, not a proof that every listed call executes on every path. Short complete implementation bodies are included where especially useful.
Complete routine and reserved-slot catalog
This subsystem declaration has no routines or skipped slots in the inspected profiles.
