Hi all, I am receiving messages from a message_queue via the blocking receive(...)-method from a separate boost::thread. When I interrupt this thread, the receive(...)-method never returns (not even with an thread::thread_interrupted exception). Am i doing something wrong or could this be a bug in message_queue? The situation I am talking about is illustrated by the following program never returning: #include <boost/thread.hpp> #include <boost/interprocess/detail/config_begin.hpp> #include <boost/interprocess/ipc/message_queue.hpp> #include <iostream> #include <vector> using namespace boost::interprocess; void receive() { try { message_queue mq(open_or_create, "message_queue", 100, sizeof(int)); unsigned int priority; message_queue::size_type recvd_size; int number; std::cout << "Trying to receive one int..." << std::endl; mq.receive(&number, sizeof(number), recvd_size, priority); } catch(interprocess_exception &ex) { message_queue::remove("message_queue"); std::cout << "Exception occurred: " << ex.what() << std::endl; } catch(boost::thread_interrupted &ex) { std::cout << "Thread interrupted. " << std::endl; } } int main() { message_queue::remove("message_queue"); boost::thread t(receive); t.interrupt(); t.join(); } #include <boost/interprocess/detail/config_end.hpp> Thanks! Michael
