I love C where types are basically a suggestion rather than a rule

Really wise. Never touch a running system, unless you really know how to fix it :rolleyes: ;P :-D
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.
That's the fun! Make a change and watch it break and fix the break is the only way to understand ancient code.

Then there are unions. Essentially a compiler-driven cast with no type conversions what so ever. It's in-memory aliasing. It takes casting to an entirely new level. I have found many good uses for unions. So has Microsoft - see the LARGE_INTEGER for an example.

Yeah, I'm aware - I even adapted the approach for C# using StructLayout.Explicit. It's just that declaring a union type isn't always called for. If you're doing the cast once or twice it doesn't make a lot of sense, so i do it when it's called for.

yeah, that'll work so long as you don't stash your structs pointers this way. :)

Yeah I try not to point into the stack for longer than the context of the containing function. :laugh:

Yes to all of that. Elegant and concise. C++ is much more type safe, and yet it became heavy: hard to read and often very hard to write, a bit constrictive. C is absolute freedom, total power... and requires total responsibility.

Funny, I was thinking the same things. But then again, I've encountered code like the OP described. Usually written by electrical engineers.

The cast operator is why I can cast my struct directly to an "array" of bytes and stash it in a file. It makes me happy. It's so elegant. So concise. And so dangerous.

the file is also not compatible between architecture to the next! :( i.e. endianess for sure.. but probably computer struct paddings too! :/ though haven't used C in decades, so I am not so sure about that one...

Sometimes that doesn't matter. Sometimes you're writing software dedicated to a particular microcontroller and it expects the thing to be wired a certain way in order to run anyway.

oh well.. yes if consumer and producer is the same one, I guess it's all good! :)

I've read this subject line several times now, wanting to point out what's so wrong with it. Anyway, I think you will love Javascript.

Neither did I, until I discovered I "was using it wrong" and had some "true C++ programmer" abusing templates lambda functions like there was no tomorrow.

The C++ one is even more accurate when pointers are involved !
