strange glitches for GetGuidByKeyword

[WBR]

Today i got troubles with detouring GetGuidByKeyword function for C#

            [UnmanagedFunctionPointer(CallingConvention.Cdecl)]
            public delegate int GetGuidByKeywordDelegate(string token, ref int128 guid, int unk, int unk2); // int128 = struct with 2 ulong
            public static GetGuidByKeywordDelegate GetGuidByKeywordHandler;
            private static Detour GetGuidByKeywordDetour;
     
            GetGuidByKeywordDetour = Memory.Instance.Detours.CreateAndApply(GetGuidByKeywordHandler, new GetGuidByKeywordDelegate((string token, ref int128 guid, int unk1, int unk2) =>
            {
                    int ret = (int)GetGuidByKeywordDetour.CallOriginal(token, guid, unk1, unk2); // object ret = _targetDelegate.DynamicInvoke(args); where  params object[] args
                    return ret;
            }), "GetGuidByKeywordDetour"); 

just hook and call original. It dont crash the game but return guid as null, and all functions using unit return 0.
What i doing wrong?
Want to pass pointer for lua functions

You cannot pass a value by ref to CallOriginal since it's using a params list.

Change 'ref int128 guid' to 'IntPtr' and try that instead.

ty for response, but i was trying with IntPtr for any params in function, with same results. it would be simple, but...

    [UnmanagedFunctionPointer(CallingConvention.Cdecl)]
    internal delegate bool GetGuidByKeyWord(IntPtr pkeyword, IntPtr guid, bool unk0, bool unk1);


            Memory.Detours.CreateAndApply(getGuidByKeyword, _getGuidByKeyWord = GetGuidByKeywordDetour, "GetGuidByKeyWord");

        private static bool GetGuidByKeywordDetour(IntPtr keywordPtr, IntPtr guidPtr, bool unk0, bool unk1)
        {
            return (bool) Memory.Detours["GetGuidByKeyWord"].CallOriginal(keywordPtr, guidPtr, unk0, unk1);
        }

    [UnmanagedFunctionPointer(CallingConvention.Cdecl)]
    internal delegate bool GetGuidByKeyWord(IntPtr pkeyword, IntPtr guid, bool unk0, bool unk1);


            Memory.Detours.CreateAndApply(getGuidByKeyword, _getGuidByKeyWord = GetGuidByKeywordDetour, "GetGuidByKeyWord");

        private static bool GetGuidByKeywordDetour(IntPtr keywordPtr, IntPtr guidPtr, bool unk0, bool unk1)
        {
            return (bool) Memory.Detours["GetGuidByKeyWord"].CallOriginal(keywordPtr, guidPtr, unk0, unk1);
        }

thanks!
will test tonight, _getGuidByKeyWord = GetGuidByKeywordDetour as param - new for me.
getGuidByKeyword - pointer or delegate?

static member of the GetGuidByKeyword delegate type, I don't even know why anymore, it's been a few years.
