[erlang-questions] Proper type for passing pointer to/from linked-in driver?

What's the recommended way to pass a pointer between a linked-in driver and
the beam? I can cast it to a uint64_t and use ErlDrvUInt64 (and do the
reverse when sending it back to the driver), but maybe there's a better way?

Thanks,
Joel
