The problem is that the FILE * is based on the data segment
of the DLL.  When you pass it to the app, it does not
correspond to any stdio buffer of the app.

If you pass it back from the DLL as a FILE FAR *, you will
have to use the large model versions of the stdio routines.
This can mean some mucking around with the lib utility (to
extract the stdio routines into .obj files) if your app's
model is not large.
