FUNCTION::ADDR(3stap)

✨ function::addr 💖

okay bestie, welcome to the SystemTap Tapset Reference, section 3stap — this is the Context Functions corner of the manual, and today's main character is a lil function called addr. she's tiny, she's iconic, and she knows exactly where you are. iykyk 💅

---

NAME 🎀

function::addr — Address of the current probe point. that's it, that's the whole vibe.

---

SYNOPSIS ✨

addr:long()

---

ARGUMENTS 🌸

None. nope, zero, nada, she takes no arguments, she's self-sufficient, she doesn't need you to hand her anything 🫶

---

DESCRIPTION 💖

okay so here's the tea: addr returns the instruction pointer from the current probe's register state. like, it's telling you where in the code you literally are right now. main character energy fr.

BUT — and this is important, bestie — not all probe types have registers. if yours doesn't, then zero is returned. zero. nothing. the void. 💀 so don't be surprised if you get a big fat 0 back.

the returned address is suitable for use with functions like symname and symdata. so like, if you wanna turn that raw address into something readable, those two are your girls 🌈
