Mach

The Mach layer is the lowest userspace-visible interface of the Darwin kernel: tasks and threads, port-based IPC, virtual memory control, clocks, and exception handling. Most calls are MIG-generated RPC stubs that operate on port rights; the .defs descriptions shown on these pages are the closest thing to official documentation the interface has. Include <mach/mach.h> for the common surface.
