I have vector<double> timeStamps; How to store this vector to outside binary file in boost style? I'm trying to utilyze mapped file:

std::vector<double> timeStamps; std::string filePath("c:\\double_test.bin"); boost::intmax_t thisFileSize(maxSize); // max good value: 0x2FFFFFFF ios::filtering_ostream out; ios::file_sink fsink(filePath); out.push(fsink); //out.write(time_stamps.begin(), thisFileSize); // out.flush(); fsink.close();

Use serialization, though not sure a mapped file is what you want: template<typename Archive> struct Serializer { static void save(const vector<double>& timeStamps) { std::ofstream ofs("file.bin", std::ios::binary); Archive oa(ofs); oa << timeStamps; } }; Serializer<binary_oarchive>::save(timeStamps); See the doc on serialization, read thoroughly, make it your friend.
