C++ does not have a standardized ABI. Compilers mangle names differently, and memory layouts for classes can change. To prevent crashes, wrap your cross-platform C++ code in a flat C interface using extern "C" .
This layer contains standard, platform-agnostic C++ code. It leverages standard template libraries (STL) and abstract interfaces to ensure the exact same source code compiles on Windows, macOS, Linux, and mobile platforms. The Windows Dynamic Link Layer xplatcppwindowsdll updated
