У меня есть пример демонстрационной программы сboost :: interprocess Контейнеры контейнеров тип. Но мне нравится использовать класс и обычный класс в моей памяти процесса. Может кто-нибудь помочь мне написать конструктор, который не принимает аргументов для инициализации класса в моей текущей памяти процесса.

#include <boost/interprocess/containers/vector.hpp>
#include <boost/interprocess/allocators/allocator.hpp>
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/archive/xml_oarchive.hpp>
#include <boost/archive/xml_iarchive.hpp>
#include <shmfw/serialization/interprocess_vector.hpp>
#include <stdlib.h>     /* srand, rand */
#include <time.h>       /* time */


using namespace boost::interprocess;
//Alias an STL-like allocator of ints that allocates ints from the segment
typedef allocator<int, managed_shared_memory::segment_manager>  ShmemAllocator;

//Alias a vector that uses the previous STL-like allocator
typedef vector<int, ShmemAllocator> MyVector;

typedef allocator<void, managed_shared_memory::segment_manager >                           void_allocator;

class MyStruct {
public:
    MyVector myVector;
    //Since void_allocator is convertible to any other allocator<T>, we can simplify
    //the initialization taking just one allocator for all inner containers.
    MyStruct ( const void_allocator &void_alloc )
        : myVector ( void_alloc )
    {}
    // Thats what I like to have       
    //MyStruct ()
    //    : myVector ( ?? )
    //{}
};

int main () {

    // I would like to have something like that working and also the shm stuff below
    // MyStruct x;


    managed_shared_memory segment;
    //A managed shared memory where we can construct objects
    //associated with a c-string
    try {
         segment =  managed_shared_memory( create_only, "MySharedMemory", 65536 );
    } catch (...){
        segment = managed_shared_memory( open_only, "MySharedMemory" );
    }

    //Initialize the STL-like allocator
    const ShmemAllocator alloc_inst ( segment.get_segment_manager() );

    MyStruct *myStruct_src =  segment.find_or_construct<MyStruct> ( "MyStruct" ) ( alloc_inst );
    srand (time(NULL));
    myStruct_src->myVector.push_back ( rand() );

    MyStruct *myStruct_des =  segment.find_or_construct<MyStruct> ( "MyStruct" ) ( alloc_inst );

    for ( size_t i = 0; i < myStruct_src->myVector.size(); i++ ) {
        std::cout << i << ": " << myStruct_src->myVector[i] << " = " << myStruct_des->myVector[i] << std::endl;
    if(myStruct_src->myVector[i] != myStruct_des->myVector[i]) {
      std::cout << "Something went wrong!" << std::endl;
    }
    }


    //segment.destroy<MyVector> ( "MyVector" );
    return 0;
}
