External Building: Send an array out an outlet as a list.

    Hi all,
    I may be missing something simple, but I can't seem to figure this out from the API documentation or any online search. I want to send an array of integers out the outlet of an external as a list, eg - a message box will receive a list of individual integers all at once. I thought I had it, but it seems that my list is actually just a repetition of a single item from the list - the first value held in the array.
    If at all possible, could someone please explain how I can get something like this: myArray[16] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}; to be dumped out an outlet so that a message box connected to that outlet will show this: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15?
    As I said, this could be really obvious once I see it, but I'm only beginning to venture into building externals and despite C itself being relatively familiar, this is really confusing the hell out of me.
    Thanks.

      Thanks for the response. Nevermind being an 'expert', whatever it was, you kicked something loose in my head and I have it solved now. So thanks again for that.
      It turns out that I had a combination of problems - not least of which was an error in my loop. The other was just some 'atom' typing confusion. Anyway, my first proper (not built out of a book) external is working. Happy days.

      I'm trying to do this same thing, what I don't understand is how to actually allocate the t_atom array dynamically? So in the object struct I should probably have t_atom atomList; And according to this Max api documentation probably use this atom_alloc_array : https://cycling74.com/sdk/MaxSDK-7.1.0/html/group__atom.html#ga5601306b4b76f338501cda586a6c1fde but that doesn't really make sense to me, like what to do to reallocate/resize? How did you end up doing it Tristan? I think that atom_setlong_array makes sense but I don't understand the allocation process. Thanks!
