FUNCTION::USER_LONG_WARN(3stap)

💖 FUNCTION::USER_LONG_WARN(3stap) 💖

okay bestie, welcome to the SystemTap Tapset Reference ✨ this is the page for user_long_warn, and yes the title is giving all caps but we move 💅

---

🌸 NAME 🌸

function::user_long_warn — grabs a long value that's chillin' in user space 🫶

---

✨ SYNOPSIS ✨

user_long_warn:long(addr:long)

---

🎀 ARGUMENTS 🎀

• addr — the user space address we're pulling the long from, periodt. that's the one and only thing you gotta hand over 💜

---

🦋 DESCRIPTION 🦋

so like, this function returns the long value from a given user space address. simple. iconic. no cap 🧚

but here's the tea, and it's kind of a big deal 😭 — if the user space data is not accessible, it just returns zero and warns about the failure. it does not error. so it's the chill friend who's like "hey, that didn't work btw" instead of the one who starts a whole scene 💀

also, super important: the size of the long depends on the architecture of the current user space task — that applies to those architectures that support both 64/32 bit compat tasks. so don't come for it assuming one size fits all, because it fr fr does not 👑
