@enkiv2 @a_breakin_glass @jamey @kara @grainloom that's theoretically true

but posix itself is at odds with the c standards, so sometimes you might have a better way of expressing something in C99 or C11 or whatever you chose and it's behaving differently, or doesn't exist to begin with

for one, for the other: c's undefined behaviour makes it really really hard to reason about code
and most c programmers don't even know what's really undefined
because c isn't really a language
it's a myth, an urban legend.
it's impossible to grasp.
and a lot of that is c devs' own fault, as i wrote over here: https://mastodon.social/@hirojin/18117298
