Hi,
I want to do write this C code in haskell code, but i have some pb: int w ; char **varnames = ccl_new_array (char *, w); int i; for (i = 0; i < w; i++) { varnames[i] = ccl_new_array (char, 100); sprintf (varnames[i], "x%d", i); } I try this code unsing mallocList to (http://lpaste.net/report/712): mallocList :: [CString] -> IO (Ptr CString) mallocList xs = do let n = Prelude.length xs p <- mallocBytes (n*100) forM_ (Prelude.zip [0..] xs) (uncurry (pokeByteOff p)) return p let n = sizeOf(undefined :: CString) allocaArray w $ \var -> do xs <- peekArray (w*n) var varnames <- mallocList xs I have an error "segmentation fault(core dumped)". can someone please help me? Thank you. Lamine _______________________________________________ FFI mailing list FFI@haskell.org http://www.haskell.org/mailman/listinfo/ffi
