(C++) Prototype class from foreign DLL
(C++) Prototype class from foreign DLL
My specific help request is this:
I have a certain DLL file which I've loaded with LoadLibrary, and it works fine.
I can call a function CalcLpqCheckSum just fine, parameters are CalcLpqCheckSum(void*, int)
However, other functions all appear to be classes:

I can reference them just fine in my code but when I call the function my application freezes and crashes.
Depending on what I do, I get various 32bit return values.

How do I properly create a prototype of a class from a foreign DLL in my program?
Also, can anyone tell me what is going on in the first picture? I lack the understanding of how these functions are designed and how to prototype them.
Even if I prototype directly from a function address I still can't call the LpqSystem function with or without parameters. It crashes regardless.
