| * DIS Data Management: insertEntry |
| * |
| * This header file contains the return codes for the insertEntry routine |
| * and the function prototype. There are three different failure modes for |
| * the routine. The first indicates that no entry on the current node was |
| * chosen for the insertion. This always indicates that the current node |
| * is empty of any entry and is an extremely rare debugging error. The |
| * second mode of failure indicates a fatal split node error. It is fatal |
| * since the index has been altered in some way before the error and, since |
| * no "undo" mechanism is implemented for the baseline application, the |
| * state of the index can't be gauranteed which produces a fatal error. |
| * The third mode of failure indicates a non-fatal split node error. It's |
| * not fatal since the index is unchanged and its current state can be |
| * assumed to be still valid. |
