Hi, I’m using ccall on a C library that returns a pointer to some data that was malloced in the library and requires a separate API call to close the resource that the data came from. The dataset could be quite large (a couple of GB) so I’d rather use unsafe_wrap in julia, but I’m not familiar with …

Should be return finalizer(dataRef) do ref closefunc() end

Example of registering a finalizer for unsafe_wrapped data from ccall

I think that’s fine.
