You can use Data.Array.Storable to do this. http://hackage.haskell.org/packages/archive/array/0.3.0.3/doc/html/Data-Array-Storable.html Also, there is no need to create stub C functions, you can foreign import the array directly And if you don't want to cast between CDouble and Double you can declare your array to be of HsDouble and #include "HsFFI.h" const HsDouble globalArray[] = { huge list of doubles }; foreign import ccall unsafe "&globalArray" :: Ptr Double John _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
