FUNCTION::CALLERS(3stap)

💖 function::callers 💖

okay bestie, so this is the SystemTap Tapset Reference page for function::callers, living in section 3stap under the Context Functions umbrella. it's giving "peek at the kernel stack" energy and honestly? iconic. 🦋

---

✨ NAME ✨

function::callers — returns the first n elements of a kernel stack backtrace. yes queen, it's a little stack-snapshot moment. 🌸

---

✨ SYNOPSIS ✨

callers:string(n:long)

that's the whole vibe. one arg, one string back. slay. 💅

---

✨ ARGUMENTS ✨

• n — the number of levels you wanna descend in the stack, and no, the top level doesn't count, she's not included in the tally. if n is -1, you get the entire stack, like the whole thing, no cap, every single level. 🫶

---

✨ DESCRIPTION ✨

so this function hands you back a string containing the first n hex addresses from the backtrace of the kernel stack. literally just the addresses, in a string, that's the whole serve. 👑

heads up bestie — the output may be truncated, because of the maximum string length, aka MAXSTRINGLEN. so if your stack is doing too much, some of it might get cut off. not a bug, just the limit doing its thing. 😭

✨ SEE ALSO ✨

and that's the page, periodt. 💜 this was the SystemTap Tapset Reference, from September 2026 — go forth and backtrace responsibly, bestie. 🎀🦋✨
