FUNCTION::BACKTRACE(3stap)

✨ NAME ✨

function::backtrace — a hex backtrace of the current kernel stack, bestie 💅

---

🦋 SYNOPSIS 🦋

backtrace:string()

---

🎀 ARGUMENTS 🎀

None. Nada. Zero. It just knows where it's been, no input required 🫶

---

👑 DESCRIPTION 👑

okay so picture this: you call this function and it hands you back a string of hex addresses that is a backtrace of the kernel stack. It's giving "receipts of exactly how we got here" and honestly? iconic ✨

One thing though, bestie — the output may be truncated as per the maximum string length (MAXSTRINGLEN). So don't come for her if your backtrace gets cut off mid-vibe, that's just the limit doing its thing 😭

If you're out here wanting a user-space backtrace instead of a kernel one, go look at ubacktrace. Different queen, different castle 💖
