Not exactly. I wanted the library to work in both Microsoft's and Mono's
implementations of dotnet. Microsoft have created an extension of C++ to
work with dotnet. Mono has a C API. At initialisation time I have the
C# side call a C function passing along a bunch of "delegates", which
are seen as function pointers on the C side. The C code can then call
these function pointers in the future.

The problem is that you still have to convince a C# program to load from
within a C library. I think I'm going to have to do different things for
the different implementations to get this to work.
