| 19 | * Format a module id for printing. |
| 20 | * |
| 21 | * There are three possible formats: |
| 22 | * |
| 23 | * MODULE_FORMAT_BRIEF is the brief 6-character format, including |
| 24 | * the actual brick-type as recorded in the |
| 25 | * moduleid_t, eg. 002c15 for a C-brick, or |
| 26 | * 101#17 for a PX-brick. |
| 27 | * |
| 28 | * MODULE_FORMAT_LONG is the hwgraph format, eg. rack/002/bay/15 |
| 29 | * of rack/101/bay/17 (note that the brick |
| 30 | * type does not appear in this format). |
| 31 | * |
| 32 | * MODULE_FORMAT_LCD is like MODULE_FORMAT_BRIEF, except that it |
| 33 | * ensures that the module id provided appears |
| 34 | * exactly as it would on the LCD display of |
| 35 | * the corresponding brick, eg. still 002c15 |
| 36 | * for a C-brick, but 101p17 for a PX-brick. |
| 37 | * |
| 38 | * maule (9/13/04): Removed top-level check for (fmt == MODULE_FORMAT_LCD) |
| 39 | * making MODULE_FORMAT_LCD equivalent to MODULE_FORMAT_BRIEF. It was |
| 40 | * decided that all callers should assume the returned string should be what |
| 41 | * is displayed on the brick L1 LCD. |
