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