Establish valid source node settings for this multiplexer.
Call with wIndex starting at zero, incrementing until a non-zero return value indicates that the current wIndex is invalid, so querying should be terminated.
- Returns:
- 0 on success, or one of the HPI_ERROR_CODES.
- Parameters:
-
| phSubSys | Vestigial subsys handle (unused), may be set to NULL |
| hControl | Control handle to type HPI_CONTROL_MULTIPLEXER |
| wIndex | a 0 based index |
| wSourceNodeType | source node type - one of HPI_SOURCENODES |
| wSourceNodeIndex | a 0 based index |
