FUNCTION::SPRINT_STA(3stap)

💖 FUNCTION::SPRINT_STA 💖

okay bestie, welcome to the Context Functions chapter of the SystemTap Tapset Reference (that's the 3stap manual, iykyk) ✨

---

🌸 NAME 🌸

function::sprint_stack — bestie it returns the stack for kernel addresses, straight outta a string 🫶

---

✨ SYNOPSIS ✨

sprint_stack:string(stk:string)

---

🎀 ARGUMENTS 🎀

• stk — a string stuffed with a list of hexadecimal (kernel) addresses. that's the whole vibe. 💅

---

🦋 DESCRIPTION 🦋

so what this does is it does a symbolic lookup of all the addresses sitting in that string you handed it — and that string is assumed to be the result of a prior call to backtrace. like, that's the assignment, no cap. 📝

It returns a simple backtrace from the given hex string. One line per address. periodt.

What's in each line, you ask? 👑

• the symbol name — or, if the symbol couldn't be resolved, the hex address instead 🙈
• the module name (if found)
• the offset from the start of the function, if found. if it's not found, the offset gets added to the module instead (if found, and it goes between brackets) 🧚

It returns the backtrace as a string, and every single line is terminated by a newline character. slay. ⭐

heads up though — the returned stack gets truncated to MAXSTRINGLEN 😭 so if you want fuller and richer stacks, go use print_stack instead. that one eats. 🔥

---

💀 NOTE 💀

it is recommended to use sprint_syms instead of this function. not me telling you to switch, but like... do it. 🫶
