FUNCTI...ER_CHAR(3stap)

💖 function::user_char — it's giving "get me that char" 💖

okay bestie, welcome to the 3stap manual, aka the SystemTap tapset reference, aka where the little sysadmin goblins live 🧚✨ pull up a chair, we're grabbing one (1) single char out of user space and honestly? obsessed.

---

✨ NAME ✨

function::user_char — retrieves a char value stored in user space 🎀

no cap, that's literally the whole job. one char. from user space. slay.

---

✨ SYNOPSIS ✨

user_char:long(addr:long)

look at her. one argument, returns a long. she's lowkey minimal and highkey iconic 💅

---

✨ ARGUMENTS ✨

• addr — the user space address to retrieve the char from. that's the spot. that's where the char is chilling. you point, she fetches 🫶

---

✨ DESCRIPTION ✨

so here's the vibe: user_char returns the char value from a given user space address. that's it, that's the whole personality 💖

BUT — and this is the part you need to internalize, bestie — when the user space data is not accessible, it returns zero. not an error, not a little dramatic message, just a nice quiet 0. so if you're getting zeros back, it's not being shady, it's just telling you the data wasn't reachable fr fr 😭

⚠️ heads up: zero is the "couldn't get it" answer and it could be a legit '\0' char. the universe is mysterious like that. just know the rule as written: not accessible → returns zero. periodt.
