SMS_NTHG
This trap scans the Thing list. The Trap cannot be used in the QDOS and SMSQ/E operating systems. Look at the Notes here for a solution.
| Call Parameters | Return Parameters | ||
|---|---|---|---|
| D0.B | $2B | D0.L | Error code. |
| A0.L | Pointer to Thing name/0 | A0.L | Preserved. |
| A1.L | Unused. | A1.L | Pointer to next Thing linkage. |
Errors
| ERR_NF | Thing not found. |
Notes
- All registers not shown above are not used on entry and are preserved on exit.
- If A0 is zero, the Trap finds the first Thing in the list. Otherwise it finds the next Thing in the list after the name to which A0 points.
- On a successful return A1.L points to the linkage block of the next Thing. That Thing's name will be at $2A(A1). Setting that address in A0 and reentering the Trap allows the whole list to be scanned.
