HI Werner, No, it's the opposite: The function should expect a hook (or a struct > with a bunch of hooks) as an argument, and FreeType is calling these > hooks internally to communicate with the external SVG library. Have a > look at the function `FT_Set_Debug_Hook' for a very simple example. >
Wow. This is really really powerful. I hadn't realized this earlier. I knew things like Function Pointers exist. But I never knew something this powerful could be done using them. I have totally got it now. Now I also see why Toshiya was saying not to link any SVG library directly to FreeType. Totally get it now! :) To actually try and see if this can be done, I coded a dummy example. It works. Though I am confident that I have understood it correctly, if you do want to see my dummy example and confirm whether I have got it correctly or not, here <https://github.com/moazin/collaborate-via-callbacks> it is. There's a Readme that explains it too. After doing this dummy example, I checked out `FT_Set_Debug_Hook` and it is exactly what I expected it to be. It's a good and small example. :) Thank you Werner, I am really grateful to you that you took the time to explain this to me. Regards, Moazin
