FUNCTION::USER_UINT32(3stap)

💖 function::user_uint32 — the manual, but make it make sense 💖

ok so bestie, you found yourself a page from the SystemTap Tapset Reference, section 3stap (that's the tapset function corner of the manual world, iykyk). Sit down, grab a strawberry 🍓, and let's talk about user_uint32.

✨ NAME ✨

function::user_uint32 — Retrieves an unsigned 32-bit integer value stored in user space

like. it goes and gets a lil number out of your program's memory. not the kernel's. yours. main character energy fr 👑

---

🌸 SYNOPSIS 🌸

user_uint32:long(addr:long)

---

🎀 ARGUMENTS 🎀

• addr — the user space address to retrieve the unsigned 32-bit integer from. it's a long, it's the spot, it's the address. point at it and the function does the rest 💅

---

🦋 DESCRIPTION 🦋

Returns the unsigned 32-bit integer value from a given user space address. Returns zero when user space data is not accessible.

that's it. that's the whole vibe. you hand it an address that lives in user space, and it hands you back the 32-bit unsigned integer sitting there. if the user space data isn't accessible? you get a zero. not an error, not a crash, not drama — just 0. lowkey the chillest failure mode ever 🫶

ngl bestie, remember it's unsigned — so no negative numbers coming out of this one, and remember it's user space specifically. wrong neighbourhood, wrong result.
