// of channels, since there might be holes in the list;
// it is one more than the index number of the highest
// bound channel. Thus, it is called get_max_bound()

//
// This will return NULL if there is no channel bound on
// the indicated index. It is an error to call this if
// n is less than zero or greater than or equal to
