Re: [Haskell-cafe] Stable pointers: use of cast to/from Ptr

You mean I have to use a type like StablePtr (IORef Stuff)? Because there I can only "peek" (deRefStablePtr) the pointer, not "poke" it. I take it I should return to C a StablePtr to the new value if I don't want to use IORefs... Or else I have to use regular Ptrs with Foreign.Marshall.Alloc.malloc 2012/2/12 Antoine Latter
