Boost shared memory map
As before, I suggest using boost::unordered_map in conjunction with boost::interprocess::allocator. If you really want to write your own allocator, you'll need some kind of custom pointer that stores the offset into the shared memory block, and is able to reconstruct the correct address from that. WebI'm using shared memory from boost library in C++, i'm trying to allocate an unordered_map to share with other process. 我在 C++ 中使用来自 boost 库的共享 memory，我正在尝试分配一个 unordered_map 以与其他进程共享。 The code of server is the below: 服务器代码如下： MapCreator.h MapCreator.h

The goal was simple, expose the same interface for cross communication to C# and Python. The approach taken was to use the condition example and edit it to expose to the different ... WebThe offset between two objects in a mapped region is the same for any process that maps the mapped region, even if that region is placed in different base addresses. To facilitate the use of offsets, Boost.Interprocess offers offset_ptr. offset_ptr wraps all the background operations needed to offer a pointer-like interface.
