+** adding the change are just as described for [sqlite3_changegroup_add()].
+**
+** If the change is successfully added to the changegroup, SQLITE_OK is
+** returned. Otherwise, an SQLite error code is returned.
+**
+** The iterator must point to a valid entry when this function is called.
+** If it does not, SQLITE_ERROR is returned and no change is added to the
+** changegroup. Additionally, the iterator must not have been opened with
+** the SQLITE_CHANGESETAPPLY_INVERT flag. In this case SQLITE_ERROR is also
+** returned.
