Some stuff since I'm bored...

[Apoc]

I've hooked Framescript_SignalEvents succesfully, but my methods to do so are very alarming. (It screams YOUR DOIN IT WRONG)

        [UnmanagedFunctionPointer(CallingConvention.Cdecl)]
        protected delegate int Framescript_SignalEvent(int Event, IntPtr pFormat, SArguments Args);

pFormat points to a string that contains the formatting for the passed arguments, seperated by the % char. (Example: %s%d%d%s%f would indicate 5 arguments: String Int Int String Double)
If it's null, there obviously aren't any arguments to that event.

SArguments is... and brace your self for ugly:

            [StructLayout(LayoutKind.Sequential)]
            public struct SArguments
            {
                [MarshalAs(UnmanagedType.ByValArray, SizeConst = 14)]
                public uint[] Arguments;
            }

Believe me when I say this really was my last resort.

Ah... one of the fun nuances of .NET

.NET doesn't really support the native va_list. (It does, to some extent, but it's a real bitch to work with)

Your best bet would be something like:

public delegate int FrameScript_SignalEventDelegate(int eventId, string arguments, IntPtr vaList);

Then iterating the 'vaList' as if it were a pseudo-array. I'm fairly sure UFP delegates can't use the 'params object[] args' approach, though I may be wrong. (Worth testing?)
