41 C++ Threading: A Generic-Programming Approach

Tuesday, 28 October – 13:30-17:00 Afternoon

Kevlin Henney, Curbralan Limited, kevlin@curbralan.com

A lot has been written about multithreading, C++, and multithreading in C++. A number of different higher-level threading APIs have been proposed. Some are influenced by object models that are not necessarily appropriate to C++'s own idioms, and some suffer from looking too obviously like C API wrappers, in spite of their specific goal of API independence. In many cases, the resulting object model is less expressive, although far simpler and safer to use, than the underlying API.

This tutorial presents a refined model for threading in C++. The model is simple, idiomatic, and generic, and its thinking is more obviously unchained from the view of thread objects as C API wrappers. It entails a generic-programming approach that is more than simply using templates: it is orthogonal and open. Elements of the resulting thread programming model can also be realized in other programming languages.

Attendee background

Prerequisites: Attendees should be experienced with C++ programming and should have some experience using templates, preferably based on the STL. At least basic familiarity with concurrency concepts is also required.
