Re: [Haskell-cafe] Interfacing C++ iterators does not work as expected

Big thanks, that works for me as well. Doesn't GHC check whether a type is allowed (like CInt,...) or not (like Bool,...)? 2011/5/2 Gábor Lehel :

It works if I replace the 'bool' return type of 'finished' with int and CInt on the C++ and Haskell side, respectively, and test for (/= 0).
