uSystem annotated reference manual version 4.4

Abstract

The goal of this work was to introduce concurrency into the language C. To achieve this goal a set of library routines and definitions were created in C. The set of routines and definitions contains those needed to express concurrency, as well as some that are not directly related to concurrency. Therefore, while the focus of this work is on concurrency, all the abstractions produced from the routines and definitions are considered important. This manual does not discuss how to use the new constructs to build complex concurrent systems. The manual is strictly a reference manual for the {mu}System definitions. A reader should have an intermediate knowledge of control oow and concurrency issues to understand the ideas presented in this manual as well as some experience programming in C. This manual contains annotations set off from the normal discussion in the following way.
