When I was in the process of creating the OpenGL loader that I described in my last blog post, I forgot to add the WINAPI prefix to the function declarations. Someone pointed out to me on Twitter that the code would fail on 32-bit compilation. I checked, and it did. Addition of the WINAPI macro fixed this problem. The WINAPI macro expands to __stdcall on 32-bit compilation on Windows.

I had encountered stdcall and more of these mysterious keywords in the past, but only had a vague idea of what they did. And so I did some web research ...

This article is a result of my experiences and experiments with using OpenGL for Papaya. My first few weeks learning OpenGL were challenging, because it was very different than most of the APIs I had interacted with up to that point. I’m taking Julia Evans’ advice, and hence writing this blog post because it would certainly have helped me a year ago. Intermediate or experienced programmers may want to skip this explanation entirely.

The complete OpenGL loader code described in this post is located here. Note that the code may change in the future, so the link points ...

Full post on my blog


I embarked on my first serious foray into programming when I was in school, equipped with a Pentium III Celeron computer, a second-hand Microsoft Press book about Visual Basic 6, and a copy of Visual Studio 6 of questionable legality. I distinctly remember visually creating facsimiles of Windows forms by dragging and dropping controls, which would come to life after running the application.

This visual designing was one of the key features of Visual Basic 6, and so was the fact that it enabled you to create native-looking UI that fit right in with ...
