Hello! I have again a question to using the boost vector with shared memory objects. I managed inserting the objects of type "MyType" into the vector with the following code: typedef boost::interprocess::allocator<MyType*, managed_shared_memory::segment_manager> ShmemAllocator; typedef boost::interprocess::vector<MyType*, ShmemAllocator> MyVector; struct shm_remove{ shm_remove(){shared_memory_object::remove("MySharedMemory");} ~shm_remove(){shared_memory_object::remove("MySharedMemory");} }remover; managed_shared_memory segment(create_only, "MySharedMemory", 65536); const ShmemAllocator alloc_inst(segment.get_segment_manager()); MyVector *vector = segment.construct<MyVector>("Vector")(alloc_inst); MyType *mytype = segment.construct<MyType>(anonymous_instance)(); MyVector->push_back(mytype); The problem is that I can't manage to extract the object from the vector. I always get a null pointer or a pointer to somewhere. This is the code for the child process: managed_shared_memory segment(open_only, "MySharedMemory"); vector = segment.find<MyVector>("Vector").first; MyType *mytype = vector->at(1); // program crashes when I try to print members of the object MyType or MyType mytype = (MyType&)vector->at(1); // object is empty Does anybody have any hint or an idea what I'm doing wrong? Thank you very much for your help! Best regards, Sabine
