💖 iso646.h — the POSIX Programmer's Manual, bestie edition 💖

okay so this is iso646.h(7POSIX) from the POSIX Programmer's Manual, and I'm about to make it make sense. periodt.

🌸 PROLOG 🌸

Real talk first, no cap: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're on Linux, go consult the corresponding Linux manual page for the actual deets on Linux behavior. Or, like, the interface might not even be implemented on Linux at all. 🙈 So check before you commit, bestie.

✨ NAME ✨

iso646.h — alternative spellings. that's it, that's the whole vibe. 🦋

🎀 SYNOPSIS 🎀

#include <iso646.h>

one include, zero drama. 💅

👑 DESCRIPTION 👑

okay so here's the tea: the functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2017 defers to the ISO C standard — the ISO C standard is the main character here, we're just supporting cast. 🫶

The <iso646.h> header shall define the following eleven macros (on the left) that expand to the corresponding tokens (on the right):

and       &&
and_eq    &=
bitand    &
bitor     |
compl     ~
not       !
not_eq    !=
or        ||
or_eq     |=
xor       ^
xor_eq    ^=

eleven of them. count them. eleven. and yes, and is literally && and or is literally || and if that doesn't feel like cheating idk what does. ✨

The following sections are informative.

🌈 APPLICATION USAGE 🌈

None. not a single thing. it's giving minimalism. 💀

🦋 RATIONALE 🦋

⭐ FUTURE DIRECTIONS ⭐

None. the future is bright and also empty. 😭

🔥 SEE ALSO 🔥

None. no friends, no links, just vibes. 🙈
