Boost.Thread enables the use of multiple threads of execution with shared data in portable C++ code.

Boost.Thread enables the use of multiple threads of execution with shared data in portable C++ code. It provides classes and functions for managing the threads themselves, along with others for synchronizing data between the threads or providing separate copies of data specific to individual threads.

The Boost.Thread library was originally written and designed by William E. Kempf. For Boost 1.35+, Anthony Williams performed a major rewrite designed to closely follow the proposals presented to the C++ Standards Committee, in particular N2497, N2320, N2184, N2139, and N2094.

As of Boost version 1.50.0 Boost.Thread provides an almost complete implementation of the C++ 2011 Threads library, plus extensions such as shared locks and thread interruption.
