#includeIn this example, we create a `managed_mapped_file` and a `mapped_region` object to map a portion of memory. We then use an allocator and a vector container to store some data in the memory region. Finally, we unmap the vector from the high addresses using the `unmap_value_high()` function. The code example uses the Boost C++ Libraries package.#include #include #include #include using namespace boost::interprocess; int main() { managed_mapped_file file(open_or_create, "file.bin", 1000000); mapped_region region(file.get_segment_manager(), read_write); typedef allocator int_allocator; typedef vector MyVector; int_allocator int_alloc(region.get_address_map(), region.get_address_map()); MyVector* v = file.find_or_construct ("MyVector")(int_alloc); // ... do some vector operations region.get_address_map().unmap_value_high(reinterpret_cast (v)); return 0; }
