# @NOTimothyLottes — Following the succession (thanks) of re-trying WASAPI using this example which h
## Post 1 (2026-07-03 17:26:33)
Following the succession (thanks) of re-trying WASAPI using this example which has been pre-minimized and de-C++'ed: https://gist.github.com/mmozeiko/5a5b168e61aff4c1eaec0381da62808f#file-win32_wasapi-h - But I'm missing something on how to get the C++ as C linking to function (cross compiling), doesn't easily work out of the box.

Of course I'm missing the magic header that does the real work ... curious how messy this will get

So instead of the massive "mmdeviceapi.h" mess-ware, I defined a stupid CPP_(object,virtual_function_number) macro. This way I just have to write down the index in the VT table for the specific virtual function ...

Here is initial bring up, function call by function call. No headers, and no C++. The magic of typecasting at usage IC4_(CPP_(... is that I don't ever have to build the headers. That is at least working out well. I do line by line to test in Wine, defer fail handling until later

More on bring-up. I just run and check visually for output in the console (this time 'B055'). Since compile times are under a second, it is super fast to check as I go. Easy to see how much code bloat there is for C++ this way (doing it manually).

Example below of how much header bloat I'm factoring out using my simple macros
