//  - No instantiation of called function at each call site

I was told by @mmozeiko that Address Sanitizer (ASAN) works on Windows now. I'd tried it a few years ago with no luck, so this was exciting news to hear.

It was a pretty smooth experience, but with a few gotchas I wanted to document.

First, download and run the LLVM installer for Windows: https://llvm.org/builds/

Then download and install the VS extension if you're a Visual Studio 2017 user like I am.

It's now very easy to use Clang to build your existing MSVC projects since there's a cl compatible frontend:

#include "FunctionalPropertyModifiers.h"


void fpmCallStore::CallAll(double time)
{
    for (auto i : m_FunctionCallMap)
    {
        const fpmFunctionCalls& calls = i->value;
        calls.call_all_fn(i->key, calls, time);

    float height = 0.0f;
};

API Design: Builder APIs (October-2020)

Some time has past (three years!) since I last wrote about API specifically about coroutines style APIs so I thought why not write another one about a different API type I encounter relatively often. The builder API.

Now first let me take a step back and put this into 20,000 feet view on where builder APIs are located in the grant scheme. In general everything in computing is separated into input, processing and finally output. In its most basic form I am currently typing on my keyboard. All pressed keys are processed from the OS up to the browser I am writing this in and finally rendered and displayed on the screen as output. Of course this example is very user centric
