pinvoke

I'm trying to make sure that my Managed to Unmanaged calls are optimized. Is there a quick way to see by looking at the IL if any non-blittable types have accidentally gotten into my pinvoke calls?

I tried just writing two unmanaged functions in a .dll, one that uses bool (which is non-blittable) and one that uses ints. But I didn't see anything different when looking at the IL to let me know that it was doing something extra to marshal the bool.
