| <span class="bold"><strong>Boost.Thread</strong></span> 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. |
| </p> |
| <p> |
| The <span class="bold"><strong>Boost.Thread</strong></span> library was originally written |
| and designed by William E. Kempf. This version is a major rewrite designed |
| to closely follow the proposals presented to the C++ Standards Committee, in |
| particular <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2497.html" target="_top">N2497</a>, |
| <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2320.html" target="_top">N2320</a>, |
| <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2184.html" target="_top">N2184</a>, |
| <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2139.html" target="_top">N2139</a>, |
| and <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2094.html" target="_top">N2094</a> |
| </p> |
| <p> |
| In order to use the classes and functions described here, you can either include |
| the specific headers specified by the descriptions of each class or function, |
| or include the master thread library header: |
| </p> |
| <pre class="programlisting"><span class="preprocessor">#include</span> <span class="special"><</span><span class="identifier">boost</span><span class="special">/</span><span class="identifier">thread</span><span class="special">.</span><span class="identifier">hpp</span><span class="special">></span> |
| </pre> |
| <p> |
| which includes all the other headers in turn. |
