# MIG and C Thread Programming
A tutorial which demonstrates the use of the C Threads library primitives in
writing a multithreaded program and the use of the Mach Interface Generator
(MIG) to generate remote procedure calls for inter-process communication. Like
its companion tutorial, it is based on the Mach 2.5 system. However, the
concepts are applicable to Mach 3.0 user level programming.

# Roots
Mig is an implementation of a subset of the Matchmaker **language**.
"Matchmaker is a language for specifying and automating the generation of
multilingual inter-process communication interfaces. MIG is an interim
implementation of a subset of the Matchmaker language that generates C and C++
remote procedure call interfaces for inter-process communication between Mach
tasks."

INTERFACE GENERATOR*.

<teythoon> btw, I just realized that mig mashes two very different things
together, namely the serialization/parsing and the message
sending/receiving
<braunr> yes
<teythoon> I'd prefer it if that were separated
<braunr> me too
<braunr> that's why i want x15 to have a bare messaging interface .. :)
<teythoon> \o/
<braunr> simple (but optimized) scatter-gather
<braunr> it makes sense for mig since mach messages do include
serialization metadata such as types
