I see. In my case it made sense copy the data even if I knew a better 
way to do it. I trust Eli will show us a way to solve the offset pointer 
problem. :)

OTOH this method to workaround libffi and "stuff an array into a struct" 
does work (and people asked questions about this before). It's just that 
it's not clear what to do in the converters for such new ctype (but this 
is a problem of scheme/foreign magic and not libffi).

To recapitulate I was thinking about mentioning the
make-cstruct-type/build-list trick in the documentation (not the whole 
ctype declaration which is not general enough yet).
