static char *tuning_keys[] = {"HWL1POS", "HWL2POS", "HWL3POS", "HWL4POS"}; |
| 9 |
static char *focus_keys[] = {"HCF1POS", "HCF2POS"}; |
| 10 |
|
| 11 |
Call: status = set_HMI_mech_values(DRMS_Record_t *rec) |
| 12 |
|
| 13 |
rec should be the lev0 record after the ISP values are inserted. |
| 14 |
|
| 15 |
status != 0 probably should cause a severe warning that the mechanism |
| 16 |
position keywords are wrong. |
