Again, this —the DLL merely registers a DirectX draw call that renders text on top of the game window. 5.6 The Overlay Hook (simplified) // hooks/overlay_hook.cpp #include <xhook/hook.h> #include <d3d11.h> #include <string> #include "api/cf_api.h" --config Release The output is Release/overlay

static void WINAPI PresentHook(IDXGISwapChain* pSwapChain, UINT SyncInterval, UINT Flags) static ID3D11DeviceContext* pContext = nullptr
