It appears that I am not decorating the function properly. How do I indicate to the compiler that the c code is calling a euphoria function in execute.e ?
Yes, this is somewhat tricky. Basically, you need to call it as a callback. I think that the easiest way to do this is probably to add another machine function that takes the address of your function as a callback. Then you can store that in a function pointer in be_machine.c, and call the callback when that machine func is invoked.
