FUNCTION::CALLER(3stap)

💖 FUNCTION::CALLER 💖

ok so bestie, this one lives in the 3stap manual — that's the SystemTap Tapset Reference, and this page is hanging out in the Context Functions section, which is basically the "who even am I right now" corner of the tapset world. 🫶

---

✨ NAME ✨

function::caller — returns the name and the address of whoever called you, like a little detective for your call stack 🔍

---

🌸 SYNOPSIS 🌸

caller:string()

---

🎀 ARGUMENTS 🎀

None. not a single one. she takes zero arguments and she's still serving 💅

---

🦋 DESCRIPTION 🦋

So here's the tea, bestie: this function hands you back both the address and the name of the function that called yours. Both. At once. Iconic behaviour fr fr.

And ngl, if you wanted to do it yourself the long way, it's literally equivalent to calling this:

sprintf("s 0xx", symname(caller_addr), caller_addr)

no cap, that's the exact same thing. so like… why would you. just use caller. she ate and left no crumbs 👑
