lIndex

An integer that represents the position where the marker will be inserted.

Pass 0 to insert the marker at the beginning (so this marker will become the first marker).

Pass 1 to insert the marker after the first marker (so this marker will become the second marker).

Pass lIndex > 0 to insert this marker after the first lIndex markers.

If there are fewer than lIndex markers in the collection, the marker will be appended at the end of the collection.

Pass 0xFFFFFFFF to insert this marker at the end of the collection.
