I advise you to use a book for networking. A good book I guess covers this stuff. You won't need to read it if you don't want to, but it can be used to check things like this. Sometimes things might get too confusing when you're still learning.

When you are still at the basics sometimes you don't even know what to search. For some people it's easier for others harder

when you have little pieces of puzzle so it's not that hard to find other pieces with simple searchs. he is already in production so he will not spend time to read big books but i'm not suggesting to avoid books anyways

they could hide lil confusions behind macros, you do it from now on

inline function is not guaranteed to be inline or avoid ruining your stack etc.

btw when I tried to define some macros in c++ after some search on how bad of a practice it is (I already knew that one shouldn't prefer macros to functions, but I couldn't find alternatives) I immediately cancelled all the macros I had defined and started searching new ways 😂

Inline means the linker does whatever it wants with it, but the main point is having readable code that you can debug without having to compile it after a manual preprocessor pass

What I dislike most is that macros don't have a scope (do they?)

I usually read that some compilers may inline some others may not or it may depend on the flags. But I wonder what overhead there could be if it's a simple comparison. I guess it doesn't change much if you aren't calling it really a lot, there inline imo is better because it makes the purpose clearer. But if the function would be called really a lot won't a good compiler optimize the function calls?

Well not just comparison, there are more operations but it's still simple I guess
