Returns ""URT_STATUS_OK"" if all nodes are synchronized and proceed. |
| 37 |
Returns ""URT_STATUS_ERROR"" if an exception occurred (faulty stage value detected). |
|
| 38 |
Returns a value greater than ""URT_STATUS_OK"" but smaller than ""URT_STATUS_ERROR"" if there are nodes left to synchronize.

Returns ""URT_STATUS_SYNC_ERROR"" if an exception occurred (faulty stage value detected).

Returns ""URT_STATUS_SYNC_PENDING"" if there are nodes left to synchronize.

In the latter case, the node thread must still wait for the control event (proceed) to synchronize. |
