Does this mean that this code in add_subtree_format() should be
setting *tree_item to 'tree' (instead of NULL) here:
/* Make sure pi is initialized in case TRY_TO_FAKE_THIS_ITEM bails */
if (tree_item != NULL)
*tree_item = NULL;
Wouldn't be it simpler if we just remove 'tree_item' argument?
Cause I understand that after change *tree_item is always the same as return value?
Well, no, they'll only return the same thing if
TRY_TO_FAKE_THIS_ITEM short-cuts us out, right?
1138 proto_tree_add_subtree_format(proto_tree *tree, tvbuff_t *tvb, gint start, gint length, gint idx, proto_item **tree_item, const char *format, ... )
...
1159 pt = proto_item_add_subtree(pi, idx);
1160 if (tree_item != NULL)
1161 *tree_item = pi;
1162
1163 return pt;
And proto_item_add_subtree(pi, ...) returns pi, so *tree_item == pt == pi.
Anyway, sorry, I'm fine with this API.
If you want to ever make proto_item != proto_tree without even more refactoring it makes sense.
