Inroads DLL for Native C++ app

Hello and thank you for your help,

I am writing MicroStation apps in Native C++.  I want to use call Inroads functions for my app.  Is there an Inroads DLL for such a purpose?

I saw in the Inroads SDK that there used to be a DLM for MDL, so I assume there is probably a DLL for C++.  

Thank you for your help and direction.  I am looking forward to equipping my application with Inroads capabilities.
