FUNCTION::ERROR(3stap)

✨ FUNCTION::ERROR ✨ (3stap)

okay bestie, we're in the Logging Tapset manual and today's main character is function::error 💅

---

🌸 NAME 🌸

function::error — bestie, it sends an error message. that's it, that's the job 💖

---

🎀 SYNOPSIS 🎀

error(msg:string)

---

🦋 ARGUMENTS 🦋

• msg — the formatted message string, aka the lil text you want to scream into the void 🫶

---

👑 DESCRIPTION 👑

okay so here's the tea ☕: an implicit end-of-line gets added for you, so don't stress about newlines, she's handled ✨

staprun also prepends the string “ERROR:” to your message, so it shows up looking all official 😌

⚠️ and now the serious part, bestie, because this one is not a vibe: sending an error message aborts the currently running probe. like, it literally ends it, no cap 😭

depending on the MAXERRORS parameter, it may also trigger an exit 👀 so yeah, this is highkey a big deal.
