PduApi 2.2.1
PduApi - Toolbox
|
In a constellation using a Switch which works like a Multiplexer, the IDs returned by PDUGetObjectId are only valid if foreign interfaces use the predefined IDs from this PduApi implementation.
The reason is that
doesn't have a UNUM32 hMod Handle in the parameter list and therefore the switch can not determine which remote interface has to be asked for the ID.
To solve this issue, an extra mapping-database would have to be generated for each remote interface.
Because of performance issues it is not planned to do. But this not a problem if you use the VCI implementation of PduApi.
