The COM API is deprecated and no longer supported. Only the C++ API is what is available for use from Pharo.

On a second look at the API's documentation, the DLL is C++ not C. I don't
know, but that might have been evident by the requirement of implementing
interfaces.

well, with C++ it is a bit worse than C: because C++ compilers use
name mangling for the function names.
Means that, if you will look for exported function 'abc()', you will
probably find it under different name, like
abc@nby_xrt

How does one go about discovering these names?

apart from that, once you figure the exact correct name, you can go
and call that function.

Things is a bit different if the exported function is a member of class.

So, what i can say.. you can try and see if it rolls (or rocks).. and
if it not, then the best option would be to implement own wrapper
library (but this time in C). And then use that library from pharo.

Ok, then this is the tricky part because I have a lot of C++ classes which are interfaces to be implemented and instances of those classes to be passed into other instances of other classes in the DLL.

An example from the documentation.
'''
An instance of the class implementing IO2GSessionStatus interface must be subscribed to the session object before calling IO2GSession::login method. It is accomplished by calling IO2GSession::subscribeSessionStatus method. For example, ...

As it stands my options are to learn Clojure (which I am already in progress of doing) in order to access the API via Java. Or to learn C/C++ and NB to access the API from Pharo.

I like Pharo, but I am not sure at this point, if that is the easiest or best option. I am concerned about learning just enough C++ to shoot myself in the foot. I am also concerned that the C/C++ route will take much more significant learning than Clojure.

Going with Clojure does not automatically rule out Pharo. Depending on how much I like or don't like dealing with Clojure/Java and whether or not I would want to implement the rest of my application there. I could also choose to use it to serve the API via http/websockets to a Pharo application.

Thanks for your help.
