FUNCTION::SET_KERNEL_STRING_N(3stap)

✨ NAME ✨

function::set_kernel_string_n — bestie, this one writes a string of a given length straight into kernel memory 💖

It lives in the SystemTap Tapset Reference, manual section 3stap, and it's giving very much "guru mode only" energy, so stay tuned 👑

---

🌸 SYNOPSIS 🌸

set_kernel_string_n(addr:long,n:long,val:string)

---

🎀 ARGUMENTS 🎀

• addr — the kernel address where the string is gonna get written, like the destination of the whole operation 💫
• n — the maximum length of the string. the cap. the limit. the "don't go past this" 🚧
• val — the actual string you're writing out, the star of the show 🫶

---

💅 DESCRIPTION 💅

okay so here's the vibe: this thing writes the string you hand it up to a maximum given length, into a given kernel memory address. that's it, that's the whole job, and it does it slayfully ✨

if the string copy faults?? it reports an error. no silent failures, we don't do that here 😭

⚠️ heads up bestie: this one requires the use of guru mode (-g). do not skip that part, it's not optional, it's literally the price of admission 🔥
