Yes, I thought of doing this, but then thought it was better to use a so-called "managed" foreign pointer via newForeignPtr.
i recommend to use Ptr and switch to ForeignPtr only when you will study how to use it. overall, unsafe* functions are really unsafe, and using them without learning will lead to mysterious problems. it's like painting with eyes closed
Good point. I would do this if I planned to train or update the language model from within Haskell, but, as it stands, I just want to train it once (at the command line, using the built-in mechanisms of SRILM) and then read in the ARPA-formatted language model file for use in Haskell.
you may add problems by using unsafePerformIO. i recommend you to learn first how to manage FFI without it, make program work, and only then try to use it. eat elephant in small pieces! look into http://haskell.org/haskellwiki/IO_inside -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
