What's the best way to figure out what components of the FFI nhc98 supports in which version? RTFS?
The nhc98 web pages (included in the distribution) have some notes on what is supported and what is not. http://www.cs.york.ac.uk/fp/nhc98/ffi.html The contents of the FFI library itself is best read directly from the sources: nhc98-1.08/src/prelude/FFI/*.hs Basically very little has changed w.r.t to our support for the FFI during the last year. In particular, we have not yet updated to the latest version of the standard where the external entity string was introduced. This is on the TODO list. Hence, the feature set was essentially stable from 1.00 right up to 1.08. (A few error-handling functions - getErrNo, mkIOError, throwIOError - were added to the FFI library at Qrczak's suggestion in v1.04.) Regards, Malcolm

GHC hasn't yet picked that one up, too. But NHC still uses `Addr', which is meanwhile deprecated in GHC. I am still having the --old-ffi flag in c2hs to generate Addr compatible code, but I didn't really check closely anymore in new code that it is Addr compatible. So, that may give problems much more likely than the extent stuff. Cheers, Manuel
