+Yes, C can almost feel like an entirely different language once you develop your own base technical layer.

+Parameters are at definition site, arguments are at the usage site. So, TransformParams seems logical. But you don't really have a very meaningful "definition site", so it might be better called TransformArguments. No?

+I'm deeply confused :D

+
+The only problem here is that you cannot do this in a header file that is going to be included within a C++ source file... However, what you can do is macro out the compound literal and provide a C++20 temporary object initializer with slightly different syntax if __cplusplus is defined..
+
+**2/** @vkrajacic
+
+@falco_girgis
+
+Yeah, I haven't tested that because my codebase is purely C nowadays.
+I'm not concerned about compatibility with C++. I understand that this is not always a choice, especially when working with a codebase you didn't start.
+
+**3/** @falco_girgis
+
+Tbh, I've never encountered a scenario with supporting C++ where you couldn't still pull all the tricks like this with modern C, if you are willing to invest in the infrastructure... That includes using _Generic() switches, which aren't supported in C++... I have a macro layer which you use to declare each type and its associated call which will compile to a _Generic statement in C or... a to C++20 anonymous generic lambda doing a series of compile-time conditionals on the generic type argument and mapping it to the appropriate logic based on its type... Yeah, it's a shitshow, but you write it once and it just works. lol. https://github.com/gyrovorbis/libgimbal/blob/79722a270d2a80651d08eb0158e803c9e4a2de6e/lib/api/gimbal/utils/gimbal_scanner.h#L366

+**1/** @EskilSteenberg
+
+@vkrajacic @CaptainKraft
+
+Am i the only one who thinks this is terrible? Its incredibly confusing to read and you cant see what parameters you miss, the header file is a lot more complex to read too. You lose the WYIWYG nature of C. If you want this kind of ”clever” syntax why not use C++?
+
+**2/** @vkrajacic
+
+It might be confusing the first time you encounter it, because it's not used often in C codebases. But that's true for a lot of things in C, since you often have to invent better solutions (like strings or memory arenas).
+As I said, I use this sparingly, but where it is used, it has always provided a better API. Ideally, I strive for ZII, so I don’t need a way of setting default values and can use a designated initializers to override when needed. That’s the best case scenario, and most of my base layer functions work like that.
+This will not work with C++, as far as I know, because they messed up designated initializers. There are probably other ways to do it there, but I don’t want C++.
+
+**3/** @EskilSteenberg
+
+@vkrajacic @CaptainKraft
+
+I think its confusing every time you see it. If i read:
+
+function(x, .param = 42);
+
+The code does not communicate, what this function can do or if I'm missing a parameter.
+
+You also have to read all parameters in the function with one more level of indirection and thats slow.
+
+**4/** @vkrajacic
+
+I don’t see how this is different from:
+void PushTransform(Rect rect, TransformParams params);
+or
+void PushTransform(Rect rect, Vec2 pivot, Dim2 scale, f32 angle, b32 clip);
+You still need to read the header (or docs) to see what each argument does, and how to pass in some default value to ignore it.
+
+For what it’s worth, the pattern I use more commonly is to separate functions that take extra parameters:
+void PushTransform(Rect rect);
+void PushTransformEx(Rect rect, Vec2 pivot, Dim2 scale, f32 angle, b32 clip);
+The first one just calls the Ex version with some reasonable defaults.
+
+This works fine in most cases, but if you have a lot of arguments, you either have to make many such function permutations or force the caller to pass in all arguments, even the ones they don’t care about.
+
+**5/** @EskilSteenberg
+
+@vkrajacic @CaptainKraft
+
+I don't like:
+
+void func(StructOfInputs params);
+
+You are hiding the input, and you are forcing a memory layout. I don't even like small structs like Dim2, and Rect because they force the caller to adopt the structures of the callee. Don't force me to live in your world.
+
+**6/** @vkrajacic
+
+There’s no hiding of any kind, it’s a public POD struct.
+
+The "Don’t force me to live in your world" argument can only be made for library vendors, which I’m not. This is my codebase, and I control it. Vectors and rects are abstractions with their own API functions that operate on them. Manually passing individual components is just not worth it.
+
+If you really wanted, you could add multiple versions of functions, which I sometimes do:
+RectCreate(Vec2 min, Vec2 max);
+vs
+RectCreate(f32 minX, f32 minY, f32 maxX, f32 maxY);
+
+Yes, it enforces memory layout, but that’s kind of the point of structs, bundling data that gets used together. And vectors are a prime example of that, especially in games and renderers, because they act as primitives and are ubiquitous throughout the code.
+
+**7/** @vkrajacic
+
+@EskilSteenberg @CaptainKraft
+
+Another example in my codebase would be length based strings. I’ve built the whole API on top of those. I don’t want to go around passing char *value, int length. The point of that abstraction is that I don’t have to do that.
+
+**8/** @nicbarkeragain
+
+@vkrajacic @EskilSteenberg @CaptainKraft
+
+I don't think I could ever go back to writing C with naked arrays / strings. It's such a small cost to pass length (and capacity) around, it's so simple and makes C feel like a different language.
+
+**9/** @daniel_collin
+
+@nicbarkeragain @vkrajacic @EskilSteenberg @CaptainKraft
+
+Yeah, I'm building a whole new C codebase and I'm having a String type for sure. Makes things just nicer.
+
+**10/** @NotAttained
+
+@EskilSteenberg @vkrajacic @CaptainKraft
+
+What is the alternative though if it’s a big struct, do you just manually type out the parameters each time, even if they are largely the same?
+
+**11/** @EskilSteenberg
+
+@NotAttained @vkrajacic @CaptainKraft
+
+YES! Having to declare a variable of the struct an then assigning every member is far more cumbersome and error prone.

+It is if you're typing them all out. But the whole point of the post was about when you DON'T want to do that.
+Ideally, you'd have them zero initialized or set with some default arguments, and then just override the ones you want, via designated initializer syntax.
+At that point, it becomes less cumbersome and less error prone, because the defaults are already set up for you. You don’t have to write them again.
+If you have lots of parameters, it's almost always the case that you don't need to set each one at the call site. If you only have a few, then a struct is unnecessary.

+
+For instance, old win APIs often take a long list of parameters. In many cases, you only need a couple of options and pass 0 to everything else, e.g. NtQueryDirectoryFile.

+
+To be honest, function parameters get confusing beyond 2-3. Named parameters are much better.

+C macro approach to using optional / default / named function params, using struct designated initializers.
+Mandatory values are passed first as standard function params (rect in the example).
+Especially useful when a zero value can be made a valid value.
