@ -71,60 +71,12 @@ First add the WinFsp DLL as a delay loaded DLL. Open the project properties and
- Linker > Input > Delay Loaded Dll's: `winfsp-$(PlatformTarget).dll` - Linker > Input > Delay Loaded Dll's: `winfsp-$(PlatformTarget).dll`
Then add the function `WinFspLoad` to passthrough.c. This function consults the registry to find the WinFsp installation directory, loads the WinFsp DLL and then makes all delay loaded imports available. Then add the following lines in the beginning of `wmain`:
.`*WinFspLoad*`
