Dear Boost Grurus, First of all let me thank you for the huge effort that people like Mr. Gaztañaga has made to keep boost interprocess improved. It is a really time-saver API! I have a very basic question that, despite the large amount of documentation I've looked, I haven't clarified yet. I just want to create a global static variables (i.e. instances) for managed_shared_memory, message_queue, mutex and condition var. By now I have my app prototype (CGI) is running fine with auto vars, as appeared in the several examples: /main() { ... boost::interprocess::permissions perm; perm.set_unrestricted(); managed_shared_memory segment(create_only,"MonitorOEE_SharedMemory", 65536, 0, perm); ... message_queue mq(create_only, "MonitorOEE_MessageQueue", 256, sizeof(t_QRequest), perm); ... named_mutex mutex_waiting(create_only, namedMutex, perm); ... named_condition cdv_wakeup(create_only, namedConditionVar, perm); ... }/ All segment, mq, cdv_wakeup live in the context of the main function... Now I want them to be globally accessible from different functions. But I am not able to. I just partially succeeded creating global pointers to managed_shared_memory and message_queue. But when constructing object to the pointer segmentation faults appear... ///Global Declarations ... static boost::interprocess::message_queue *mq; static boost::interprocess::managed_shared_memory *segment; static boost::interprocess::interprocess_mutex mutex_waiting; static boost::interprocess::interprocess_condition cdv_wakeup; ... main() { .. std::auto_ptr<boost::interprocess::managed_shared_memory>ptr01(new boost::interprocess::managed_shared_memory(open_only,"MonitorOEE_SharedMemory")); segment = ptr01.get(); //this seems to work but fails when constructing objects: IPC_SOAPRequest *pSOAPRequest =segment->construct<IPC_SOAPRequest>(namedSOAPRequest)(); (the autovar counterpart works seamlessly) ... std::auto_ptr<boost::interprocess::message_queue>ptr02(new boost::interprocess::message_queue(open_only,MonitorOEE_MessageQueue")); mq = ptr02.get(); //Seems to work...(send and receive) .. //dunno how to instantiate to mutex and cond var global references } / I am sure it should be an easier and tidier way. Can you give me just the first steps to work this out? I've been sleepless a couple of nights. Eskerrik Asko!
