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.
