Given these constraints, several robust patterns have emerged for updating DLLs without full application restarts or across-platform consistency.

: They stripped out Windows-only calls, moving logic to standard C++. The Bridge

Unlike Linux and macOS, which export all symbols by default unless configured otherwise, Windows requires explicit instructions to expose functions and classes from a DLL.

This macro-driven approach allows the same header file to define a shared API boundary, whether compiling for a Windows DLL or a Unix shared object.

If you are currently using an older version (v3.x), the migration is straightforward but requires a recompilation of dependent projects.

: It likely serves as a bridge or wrapper for C++ code to run as a DLL on Windows while maintaining a structure that allows for cross-platform builds (e.g., using CMake).

If you are seeing a notification that a file with this name was "updated," it generally indicates:

While Linux allows overwriting a .so file even if it's in use (the old inode remains until all references close), Windows does not. Thus, update strategies that work on POSIX systems fail on Windows, demanding a separate mechanism.

// include/xplatcppwindowsdll.h #pragma once #include "xplatcppwindowsdll_export.h" #include class XPLAT_API XPlatLibrary public: XPlatLibrary() = default; ~XPlatLibrary() = default; // A cross-platform method visible to executing clients std::string GetPlatformName() const; ; Use code with caution. Updating the Build and Compilation Pipeline

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 ).

The game executable expects an older API pattern, but the updated DLL has modified its export functions.
