Sorry for replying late!
We don't have the nifGetObjectDictionary function, so may I make a guess that you mean nifGetObjectDescription? If I'm right, there will be some trouble.
To be honest, basically we don't support the APIs which are not included in the "NI-FBUS CM Function Reference Manual". In further, would you please let me know how you find this kind of internal functions? We cannot support it until we verify the customer has bought the complete version of APIs package and this package is still in the support period. If it matches your case, would you please help me in the verification? And then we can support the details for your question later.
On the other hand, we don't have the APIS to upload/read Schedule Domain now.
