Is there anyone who can help me / explain me how to instal a low lvl hook just for specified running process ?
Theres a UDF file for Autoit that allows u to track mouse
using Callback to a low lvl mouse hook , but its a overall info
Code:

Ok so i did a bit of research, and ended up with this
Code:
unc HookMe()

$g_hStub_KeyProc = DllCallbackRegister("_KeyProc", "long", "int;wparam;lparam")
$hMouseProc = DllCallbackRegister("_MouseProc", "int", "int;ptr;ptr")

$g_hHook = _WinAPI_SetWindowsHookEx($WH_KEYBOARD_LL, DllCallbackGetPtr($g_hStub_KeyProc), $hMod)
$g_hHookm = _WinAPI_SetWindowsHookEx($WH_MOUSE_LL, DllCallbackGetPtr($hMouseProc), $hMod)
EndFunc ;==>Example
Func _MouseProc($nCode, $wParam, $lParam)

$tMOUSEHOOKS = DllStructCreate($MSLLHOOKSTRUCT, $lParam)
If Not ($nCode < 0) Then

EndFunc ;==>Cleanup
^
This code (if i wrote it correctly should catch up events with LL_Injected flag
clean them and send forward using CallNextHookEx
Look like its working but :P
Mouse is acting weird due to delays.
Im not an AutoIt Vet if it comes to dllcalls and hooks like this one
I dont want to screw up anything.... so if theres anyone willing to help me, dm me and ill send u my discord tag in case of future questions
