The /DELAYLOAD linker flag on Windows allows a DLL to be loaded only when its first function is called. An updater can replace the on-disk DLL during a quiescent period, and the next function call will load the new version. However, if the old version is still resident in memory, FreeLibrary must be called first—which is tricky if any threads are executing code inside it. Hot patching (rewriting function prologues to jump to new code) is possible but extremely fragile and not cross-platform. xplatcppwindowsdll updated
The xplatcppwindowsdll project is designed to bridge the gap between Windows-centric C++ development and cross-platform (xplat) requirements. Historically, these libraries relied heavily on Microsoft-specific calling conventions and system APIs, making them incompatible with non-Windows environments. return TRUE; The /DELAYLOAD linker flag on Windows

On Windows, the COM framework provides a rigorous binary standard for interfaces and versioning (via IUnknown and CLSIDs). By implementing a DLL as a COM server with a new CLSID for each breaking change, cross-platform code can abstract COM behind a platform-specific wrapper. The downside: COM is Windows-only, though frameworks like XPCOM (Firefox) or Qt's plugin system offer analogous patterns for other OSes.
