RE: mistake in definition of CFile?

The FFI spec says (in section 6.2) that CFile represents the C type 'FILE' and has Eq and Storable instances.

Is this a mistake? FILE is opaque and AFAIK, you can't copy or compare its contents and expect it to work. I can think of two possible interpretations:

* the table should say CFile is equivalant to 'FILE *'. * One is meant to use 'Ptr CFile' and no Eq or Storable instances should exist for CFile. (it is opaque)

The latter, I think. Cheers, Simon
