But isn't it bad practice? Like, isn't it seen evil when you often use them? Especially because they are hard to debug? (I can't watch the video currently)
I think it depends, trivial
min()andmax()style functions are very common and considered acceptable, though I guess you could have been usinginlinefor the last two decades...The only time I got any serious usage out of preproc functions was writing a driver for an AT-command set cellular modem which involved writing a ton of repetitive code for each AT command.
I think I would prefer this sort of content in wrtten form though, cause I do it so seldom, I always need to look up syntactic specials like 'stringizing' where I even tend to forget the names of the concepts :)
Isn't
inlinetechnically just a suggestion to the compiler though? It's not necessarily guaranteed to inline it.Sure. So? If the compiler feels it's more efficient not to inline, who am I to judge? As far as I know there's nothing keeping the compiler from recognizing repetitive code generated by macros and factoring out into a single assembly routine...
