[Windows XP, VC++ 10, boost 1.46] When interrupt a future, the future.get() throw boost::unknown_exception, Not boost::thread_interrupted. Class boost::thread_interrupted should have a base class for current_exception_impl() to catch it ? or use BOOST_THROW_EXCEPTION in interruptible_wait) ? /////////////// namespace boost { class thread_interrupted {}; } exception_ptr current_exception_impl() { try { throw; } catch( exception_detail::clone_base & e ) { return exception_ptr(e.clone()); } ................ catch( std::exception & e ) { return exception_detail::current_exception_unknown_std_exception(e); } catch( boost::exception & e ) { return exception_detail::current_exception_unknown_boost_exception(e); } catch( ... ) { return exception_detail::current_exception_unknown_exception(); } // unknown_exception////////////////// ERROR: Throw in function (unknown) Dynamic exception type: class boost::exception_detail::clone_impl<class boost::unknown_exception> std::exception::what: Unknown exception //code ///////////////////// #include <boost/thread.hpp> #include <boost/date_time/posix_time/posix_time_types.hpp> #include <boost/thread/future.hpp> using namespace boost::posix_time; using namespace boost; int main(int argc, char** argv) { boost::packaged_task<int> pt( [=]()->int { this_thread::sleep(seconds(1000)); return 0; } ); boost::unique_future<int> fi = pt.get_future(); boost::thread task(std::move(pt)); // launch task on a thread task.interrupt(); try { int v = fi.get(); } catch (boost::exception& exc) { std::cerr << "ERROR: " << boost::diagnostic_information(exc) << std::endl; } }
