<p>Do any asynchronous connectors exist for Mysql that can be used within a C or C++ application? I'm looking for something that can be plugged into a <a href="http://en.wikipedia.org/wiki/Reactor_pattern" rel="noreferrer" title="reactor pattern">reactor pattern</a> written in <a href="http://www.boost.org/doc/libs/release/libs/asio/index.html" rel="noreferrer" title="Boost.Asio">Boost.Asio</a>.</p>

<p>[Edit:] Running a synchronous connector in threads is not an option.</p>

. You'll need to understand the ODBC APIs though.
