Check if system has joined into AAD. If joined, retrieve all the logged-in AAD domain users...

Hi, 

My win2k12 r2 64-bit system was joined into On-Premise AD and able to get domain details(domainDns, domainFlat) by DsRoleGetPrimaryDomainInformation API, and all the logged-in users by NetWkstaUserEnum  API. 

These win32 APIs fail to provide above specified details if my system has joined into AAD.

What the win32 APIs(my application is based on C++),  have to use to get domain details(domainDns, domainFlat) and all the logged-in users?

Thank you for your help in advance.
