FUNCTION::USER_STRING_N(3stap)

💖 function::user_string_n 💖

okay bestie, so this one lives in the SystemTap Tapset Reference, manual page FUNCTIO...R_STRIN(3stap) — yes the header is literally truncated like that, it's giving mysterious ✨ — and it's all about pulling a string out of user space. no cap.

---

🌸 NAME 🌸

function::user_string_n — retrieves a string of a given length from user space 🫶

---

✨ SYNOPSIS ✨

1) user_string_n:string(addr:long,n:long)

2) user_string_n:string(addr:long,n:long,err_msg:string)

---

🎀 ARGUMENTS 🎀

• addr — the user space address you wanna grab the string from 📍
• n — the maximum length of the string (this matters when it's not null terminated, iykyk)
• err_msg — the error message that gets returned when the data just isn't available 😭

---

💅 DESCRIPTION 💅

1) Returns the C string of a maximum given length from a given user space address. Reports an error in the rare cases when userspace data isn't accessible at that address. 🙈

2) Returns the C string of a maximum given length from a given user space address. Returns the error message string you gave it in the rare cases when userspace data isn't accessible at that address. so like, you get to pick your own sad message 💀

lowkey both versions do the same iconic job, the only glow-up is whether you choose the error message or the tapset does. ✨
