[Mono-dev] internal call from c# to c++

[Erik Christensen]

Hi,

Trying to make a program, where it's possible to use C# to script to the
Core (C++ code).

I don't want to use P/Invoke.

I can run the Internal calls  example from 
http://http://www.mono-project.com/Embedding_Mono
http://www.mono-project.com/Embedding_Mono  without a problem. And
everything's fine as long as the function(s) doesn't use any argument(s).
However, I just can't seem to get a hold of the arguments on the C++ side.
Can someone pass an advice on this please?

Testcode is:

**************
C# :
**************
using System;
using System.Runtime.CompilerServices;

class Test
{

[MethodImplAttribute(MethodImplOptions.InternalCall)]
    extern private int calcsum(int a, int b);

static void Main(string[] args)
    {
        Test t = new Test();
        Console.Write(t.calcsum(3,3));
    }
}


**************
C++ : (mono embed)
**************
//include's

int calcsum(int a, int b)
{
   return (a+b);
}

int main(int argc, char* argv[]) 
{

//...

mono_add_internal_call ("Test::calcsum(int,int)", calcsum);

//...
}

It'll compile, and run, however the result is just random numbers from
somewhere in the memory, which should mean that the "a" and "b" variables
aren't set from the c# side (ie. the 3 is lost somewhere).

Really hope anyone can enlighten me on this one.

Cheers!
