nbcon_kthread_func(9)

💅 nbcon_kthread_func(9) — the printer thread function, bestie ✨

okay so this is a page from the Kernel API Manual (yes the whole thing lives in that world), and it's about nbcon_kthread_func — the printer thread function. that's the whole vibe. it's the function your kthread runs when it wakes up to actually push console records out. iconic behavior, no notes. 🎀

---

🌸 NAME 🌸

nbcon_kthread_func — literally the printer thread function. that's it, that's the name, she's a printer thread and she has a function. periodt. 💅

---

✨ SYNOPSIS ✨

int nbcon_kthread_func (void *__console );

one return type, one argument, very demure, very mindful. 🫶

---

🦋 ARGUMENTS 🦋

• __console — the console to operate on 💖 that's the one single thing this function needs from you. hand her a console and she'll do her little thread thing on it.

---

⭐ RETURN ⭐

returns 0. that's it. zero. the humble little 0, main character of every good return value. 😌

---

heads up bestie: the page literally just says 0 and nothing else, so don't be out here inventing a whole dramatic failure story okay 😭 the docs said zero and we're saying zero. no cap.
