edac_get_owner(9)

💅 edac_get_owner(9) — the Kernel API Manual, but make it make sense

okay bestie, welcome to edac_get_owner, a tiny little function in the Kernel API Manual that takes zero arguments and tells you exactly one thing. no cap, it's giving "small but mighty" 💖

---

✨ NAME ✨

edac_get_owner — returns the owner's mod_name of EDAC MC 🫶

like, it's the little function whose whole personality is "whose module is this, actually?" and honestly? respect.

---

🌸 SYNOPSIS 🌸

const char * edac_get_owner (void );

that's it. that's the whole vibe. a const char * and a void and zero drama ✨

---

🎀 ARGUMENTS 🎀

• void — no arguments 💀 literally none. nothing. the void is the point. you show up, you pass nothing, and it's fine. iconique.

---

🦋 RETURN 🦋

so here's what you get back, and there are exactly two (2) outcomes, bestie, keep up 👑

• a pointer to the mod_name string — this happens when EDAC MC is owned 🎉
• NULL — this happens otherwise 🙈

that's the whole return contract. no structs, no error codes, no little surprise extras. if it's owned you get the string, if it isn't you get NULL, and you will be checking that NULL before you dereference it because we are not about that segfault life fr fr 💅

heads up queen: NULL is a real, expected return value here — it is not an error code, it just means "not owned". check before you use it, every single time 😭
