Re: [Haskell-cafe] Sometimes pinned memory?

gcross:

Hey everyone! Do you have any suggestions for how I might allocate an aligned block of memory that I can pin while making foreign calls, but leave unpinned the rest of the time to potentially improve allocation and garbage collector performance? Or is this even a good idea?

There's no pinned/unpinned memory. You have to pick one. * Use a ForeignPtr to allocate pinned memory (mallocForeignPtr) if you want it mostly poinned. Otherwise, you'll need to copy from unpinned to pinned. -- Don
