💖 atclass(3) — ASO class handling 💖

okay bestie so this is a page from the AtFS Toolkit Library — yes, the whole atclass(3) manual — and it's literally just two little functions that tell you stuff about your attributed software objects (asos). tiny page, big vibes. let's get into it 🫶

✨ NAME ✨

atFileClassExt, atIsDerived — ASO class handling

🌸 SYNOPSIS 🌸

#include <atfs.h>
#include <atfstk.h>

char *atFileClassExt (Af_key *aso);

int  atIsDerived (Af_key *aso);

like. two includes. two functions. we love a minimal queen. 👑

🎀 DESCRIPTION 🎀

okay so first up: atFileClassExt hands you back a short string — and when we say short we mean it, it's only one or two characters long — that shows off the class of the attributed software object (aso) you passed in. think of it as a little ✨vibe check✨ for your file.

and get this: it's a superset of the file class symbols that the ls -F command sticks onto filenames. so if you already know those, you're basically already fluent, no cap. 💅

here's the full symbol lineup:

• / — Directory. 📁
• @ — Symbolic Link.
• = — Socket.
• * — Executable.
• $ — Derived.
• ^ — Locked. 🔒

and bestie, some of these can combine. in particular — especially — the circumflex (^) can be combined with any of the other symbols, which gives you a two-letter string instead of a one-letter one. so yeah, that's why it said one or two characters. it was foreshadowing. 🦋

then there's atIsDerived, which is the simpler sister function. she checks whether the aso you gave her lives in a derived object cache — in which case you get TRUE — or not — in which case you get FALSE. that's it. that's the whole function. honest work. 🌸

and that's the page, bestie!! go forth and class-ify your asos 🧚
