Disclosure: On this site you won’t find specific advice on “how to call function xyz()”. Interpreting C++ ARM and #pragma dwim is also out of scope.
We’re treating our readers as intelligent beings who can use Google and/or StackOverflow, where all such specific questions were answered more than once.
What you will find is opinions, more opinions, and even more opinions on all the aspects of software development - and with a large chunk of them based on real-world experience too.
