yes.

one of the function parameters is a flag whether the line is currently 
selected, so you end up with something like:

gboolean
my_select_function (GtkTreeSelection *selection,
                               GtkTreeModel *model,
                               GtkTreePath *path,
                               gboolean path_currently_selected,
                               gpointer yourdata)
{
    if (path_currently_selected)
    {
         ..... going to be unselected => remove row from your own list .....
    }
    else
    {
         ..... going to be selected => add row to your own list .....
    }

    return TRUE; /* yep, allow selection/unselection to happen */
}

Doesn't it call the select function for each and every line in between those 
two if you select multiple lines? I think it does.
