The comparison function -is called when it is necessary to compare a data item specified by the -application with a data item currently stored in the tree.

In addition, the comparison function must cause the data -items in the set to be <i>well-ordered</i>. The comparison function -must correctly handle any data item values used by the application -(possibly including zero-length data items).
