ERROR(9P)

💖 ERROR(9P) 💖

okay so this is a page from the 9P manual (section 9P, obviously, it's giving very niche-and-proud 💅) and it's literally just about one little message whose whole job is to say "bestie, that did NOT work." short page, huge slay. let's get into it 🎀

✨ NAME ✨

error — return an error 🫶

like, that's it. that's the whole gig. it returns an error. icon behavior honestly.

✨ SYNOPSIS ✨

size[4] Rerror tag[2] ename[s]

look at her go 😭 so compact, so efficient, so not-your-usual-verbose-manpage-energy.

🌸 DESCRIPTION 🌸

okay so the Rerror message — and listen, there is literally no Terror, do not go looking for one, she does not exist 🙈 — is the one you send back when a transaction fails. it carries an error string that describes what went wrong. it's the "it's not you, it's the syscall" text 💀

and here's the vibe: Rerror replaces the reply message that would normally come back on a successful call. so instead of the happy-path reply you were expecting, you get this instead. one or the other, not both, no cap ✨

its tag is the tag of the failing request — so you always know exactly which call this error is clapping back at 👑

🦋 the truncation thing (still DESCRIPTION, don't @ me) 🦋

by convention, clients may truncate error messages after ERRMAX-1 bytes. ERRMAX is defined in <libc.h>. 💀

so yeah, ERRMAX-1 bytes is the vibe ceiling — past that, clients are allowed to just chop the string off. not required, just ~convention~. and if you're wondering where ERRMAX even comes from? <libc.h>, bestie. it's always <libc.h>. 🌈

👑 SEE ALSO 👑

okay there's genuinely no SEE ALSO section on this page, and honestly? she said "I'm self-contained, I don't need anyone." main character energy fr fr 💅

that's the whole page, bestie — short, sweet, and absolutely refusing to elaborate further 🧚
