FUNCTION::KERNEL_STRING_N(3stap)

💖 function::kernel_string_n — ok bestie, let's grab a string 💖

So this is a page from the SystemTap Tapset Reference manual, and it's all about pulling text out of kernel memory. Slay. Let's go. 🦋

✨ NAME ✨

function::kernel_string_n — grabs a string of a given length straight out of kernel memory 🫶

---

🌸 SYNOPSIS 🌸

kernel_string_n:string(addr:long,n:long)

---

🎀 ARGUMENTS 🎀

• addr — the kernel address you're yanking the string out of, bestie. That's where it lives. 📍
• n — the max length of the string, in case it's not null terminated. Basically a lil safety cap so we don't run away forever. 💅

---

👑 DESCRIPTION 👑

Returns the C string from a given kernel memory address — up to a maximum length you specify. If it hits a string copy fault? It reports an error. That's it, that's the whole vibe. 💀

Heads up: string copy fault = error reported. No silent nonsense here, fr fr.
