I am trying to use a vector with a managed_mapped_file. http://www.boost.org/doc/libs/1_35_0/doc/html/boost/interprocess/vector.html seems to indicate this can be done. When I try to run the code below, it fails with a "bus error" (on OS X) after printing "Entering item in vector". What am I doing wrong? Also, how can I grow this managed_mapped_file as I add things to the vector? I get runtime errors using the managed_mapped_file::grow() function. The code below should just fill up a vector with powers of 2, and print it. I am trying to understand the library before I implement it for something real. Code below: #include <boost/interprocess/file_mapping.hpp> #include <boost/interprocess/mapped_region.hpp> #include <boost/interprocess/containers/vector.hpp> #include <boost/interprocess/managed_mapped_file.hpp> #include <boost/interprocess/managed_shared_memory.hpp> #include <boost/interprocess/containers/vector.hpp> #include <boost/interprocess/allocators/allocator.hpp> #include <iostream> #include <fstream> #include <cstring> #include <cstddef> #include <cstdio> #include <cmath> int main () { using namespace boost::interprocess; try{ std::cout << "Starting" << std::endl; managed_mapped_file mfile (open_or_create, "MyMappedFile", 65536); std::cout << "Mapped file" << std::endl; typedef allocator<int, managed_shared_memory::segment_manager> ShmemAllocator; typedef vector<int, ShmemAllocator> MyVector; const ShmemAllocator alloc_inst (mfile.get_segment_manager()); std::cout << "Making vector" << std::endl; MyVector* vec = mfile.construct<MyVector>("vec")(alloc_inst); std::cout << "Made vector" << std::endl; std::cout << "Filling vector" << std::endl; int i = 0; for(i = 0; i < 63; ++i) { std::cout << "Entering item in vector" << std::endl; vec->push_back(pow(2,i)); std::cout << "Entered item in vector" << std::endl; } std::cout << "Filled vector" << std::endl; std::cout << "Size of vec is:\t" << vec->size() << std::endl; std::cout << "Reverse printing contents of vector" << std::endl; for(i = vec->size()-1; i >= 0; --i) { std::cout << "At " << i << ":\t" << vec->at(i) << std::endl; } std::cout << "Printed contents of vector" << std::endl; } catch(interprocess_exception &ex){ std::remove("MyMappedFile"); std::cout << ex.what() << std::endl; return 1; } std::remove("MyMappedFile"); return 0; }
