      public com.sun.jna.Pointer invoke(com.sun.jna.Pointer ptr, SizeT old_size, SizeT new_size)
      Description copied from interface: ReallocFunc
      Resize a previously allocated block ptr of old_size bytes to be new_size bytes. The block may be moved if necessary or if desired, and in that case the smaller of old_size and new_size bytes must be copied to the new location. The return value is a pointer to the resized block, that being the new location if moved or just ptr if not.

      ptr is never NULL, it’s always a previously allocated block. new_size may be bigger or smaller than old_size.
