Xplatcppwindowsdll Updated 【OFFICIAL × BREAKDOWN】

The version number has jumped from v2.1.4 to v3.0.0—a semantic versioning leap that indicates breaking changes but also major new capabilities. Here’s what’s new.

Instead of replacing the active DLL, the updater writes the new version to a separate file (e.g., mylib_v2.dll). The main application, upon a safe signal (e.g., after completing a transaction), unloads the old DLL via FreeLibrary and loads the new one using LoadLibrary with an absolute path. This avoids file locks entirely. The challenge is to transfer any necessary state from the old DLL instance to the new one via a handshake function (e.g., GetState and SetState). xplatcppwindowsdll updated

A unified macro PLATFORM_API now replaces manual #ifdef _WIN32: The version number has jumped from v2

// platform_api.h
#ifdef _WIN32
  #ifdef XPLATCPP_EXPORTS
    #define PLATFORM_API __declspec(dllexport)
  #else
    #define PLATFORM_API __declspec(dllimport)
  #endif
#else
  #define PLATFORM_API __attribute__((visibility("default")))
#endif

All public classes and functions are marked with PLATFORM_API.
This ensures only intended symbols are exported from the DLL, reducing binary size and collision risk. All public classes and functions are marked with
