Injector CLI

wildm_inject.exe (source injector/wildm_inject.c) loads the WildM client DLL into Ghost Recon Wildlands without modifying any game file — the same principle as FiveM. It is installed next to dinput8.dll in %USERPROFILE%\WildM\client\ and run by the launcher.

Usage

wildm_inject.exe --url <platform-url> <path\to\dinput8.dll>
wildm_inject.exe <path\to\GRW.exe> <path\to\dinput8.dll> [game arguments…]

--url mode (used by the launcher)

wildm_inject.exe --url uplay://launch/1771/0 "%USERPROFILE%\WildM\client\dinput8.dll"
wildm_inject.exe --url steam://rungameid/460930 "%USERPROFILE%\WildM\client\dinput8.dll"

1. Refuses to start if a GRW.exe is already running.
2. Opens the URL with ShellExecuteW: the game is launched normally by its platform, which checks the licence.
3. Watches for a new GRW.exe process for up to 3 minutes (Ubisoft Connect can be slow).
4. As soon as it appears, loads the DLL with a remote thread on LoadLibraryW and verifies the module is present (full path comparison).
5. Keeps watching that process for 20 s: if it exits and another GRW.exe appears (Ubisoft Connect relaunching the game through UbisoftGameLauncher), it injects the new one.

Direct mode (development)

1. Refuses to start if a GRW.exe is already running.
2. CreateProcessW(GRW.exe, CREATE_SUSPENDED) with the game folder as working directory and the extra arguments appended.
3. Writes the DLL path into the process and queues LoadLibraryW as an APC on the main thread, so it runs during process initialisation, before any game code; then ResumeThread.
4. Checks for up to 60 s that the client is loaded. If the process exits and Ubisoft Connect relaunches the game, the new GRW.exe is injected with a remote thread.

In both modes, when the game later loads dinput8.dll by name, Windows returns the module already in memory — the WildM proxy.

Output

Exactly one line on stdout, read by the launcher:

Output	Exit code	Meaning
OK pid=<pid> mode=url	0	Injected (--url mode)
OK pid=<pid> mode=demarrage	0	Injected at start-up (direct mode)
OK pid=<pid> mode=relance	0	Injected after a relaunch by Ubisoft Connect (direct mode)
ERR usage: …	2	Wrong arguments
ERR dll introuvable	3	The DLL path does not exist
ERR GRW.exe tourne deja : ferme le jeu avant de rejoindre un serveur	4	The game is already running
ERR lancement <url> / ERR CreateProcess <code>	5	Could not open the URL / start the game
ERR injection <code>	6	Could not queue the APC (the suspended game is terminated)
ERR relance via Ubisoft Connect : injection impossible	7	Relaunch detected but injection failed
ERR le jeu n'a pas demarre (ou injection impossible) / ERR le client ne s'est pas charge dans le jeu	8	Timeout

The launcher runs it with a 240 s timeout and shows Lancement du jeu : <message> for any ERR.

Building

Plain Win32 C, no dependencies beyond shell32 (for ShellExecuteW). It is built together with the client into grw-mp/build/ by the client agent.
