Xplatcppwindowsdll Updated
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.
The tedious __declspec(dllexport) dance has been modernized. The update introduces a cleaner macro:
// New in xplatcppwindowsdll v4.2 #define XPLAT_API __declspec(dllexport)
extern "C" XPLAT_API int InitializeEngine(const char* config_path); XPLAT_API void ProcessData(uint8_t* buffer, size_t len);
Furthermore, the DLL now supports Delay-Loading, allowing your Windows executable to fail gracefully if the cross-platform resources aren't available.
Upgrade in a branch, run the full matrix of builds/tests, and prefer the new exported CMake targets rather than manual symbol/export management. The update primarily improves build reproducibility and cross-toolchain behavior while keeping public APIs stable.

This is the story of "XPlatCppWindowsDll," a project born from the need to share high-performance C++ code across different platforms while maintaining its home on Windows. The Problem: The "Windows Only" Trap The project began as a standard Windows Dynamic-Link Library (DLL)
. It was efficient, but it was stuck. Because it relied on Windows-specific APIs and used Microsoft-specific calling conventions , it couldn't easily run on Linux or mobile. The Solution: A Cross-Platform Evolution
To "update" the project into a truly cross-platform (XPlat) entity, the developers followed a strict path of modernization: Isolating the Core
: They stripped out Windows-only calls, moving logic to standard C++. The Bridge
: Instead of exporting complex C++ classes (which can break between different compilers), they used a pure C interface extern "C"
. This ensured the library could be called by almost any language or platform. Unified Build System : They ditched manual Visual Studio solutions for , allowing them to generate build files for both Windows ( ) and Linux ( ) from one codebase. WSL Integration : Using the Windows Subsystem for Linux (WSL)
, they could build and test the Linux version without ever leaving their Windows environment. Building cross platform apps with C++ in Visual Studio 2022

You can fill in the bracketed sections or delete the bullet points that don't apply.
The biggest headache—exporting symbols—has been eliminated. The new version introduces a XPLATCPP_PUBLIC macro that works flawlessly across MSVC, Clang, and GCC.
Old way (manual):
#ifdef _WIN32 #ifdef MYLIB_EXPORTS #define MYLIB_API __declspec(dllexport) #else #define MYLIB_API __declspec(dllimport) #endif #else #define MYLIB_API __attribute__((visibility("default"))) #endif
class MYLIB_API MyClass ... ;
New way with updated xplatcppwindowsdll:
#include <xplatcpp/api.h>
class XPLATCPP_PUBLIC MyClass ... ;
The updated module automatically generates a .def file for MSVC, ensuring that even C++ mangled names are correctly exported without needing extern "C" wrappers.
