Hi Ben,
here you do not need to use an opaque object (is not that what you want).
in this case you have two paths to follow:
1) you just declare CXIndex as an alias of ExternalAddress (or void*). This
will work but is not cool because UFFI will answer you an ExternalAddress and
probably you
I have a type definition...
typedef void *CXIndex;
which I believe reads "CXIndex is a pointer at void"
that is returned by...
CXIndex clang_createIndex(int x, int y)
This seems an obvious candidate to be a FFIOpaqueObject defined like this...
FFIOpaqueObject subclass: #CXIndex
