Thank you.
I originally tried the 'out' modifier, and I got a warning[1].
I looked at the tutorial[2] and it seems to indicate the 'ref'
modifier is used as in your example. It indicates that the 'out'
modifier is called like this:
SList<string> list;
populate_list (out list);
It would be initialized on the callee side.
static void populate_list (out SList<string> list) {
list = new SList<string> ();
[...]
}
