mei_cl_alloc_linked(9)

💅 mei_cl_alloc_linked (9) — Kernel API Manual, bestie edition

Okay so picture this: we're deep in the kernel, in the 9 section of the manual, and today's main character is mei_cl_alloc_linked. That's the one that allocates and links a host client. That's literally the whole NAME section, no notes. 🎀

---

✨ SYNOPSIS ✨

struct mei_cl * mei_cl_alloc_linked (struct mei_device *dev );

That's it, that's the whole vibe. It hands you back a struct mei_cl * pointer. Slay. 🌸

---

🫶 ARGUMENTS 🫶

• dev — the device structure. That's it, that's the whole argument. It's giving "one job, done correctly." 👑

---

⭐ RETURN ⭐

• cl on success 💖
• ERR_PTR on failure 😭 (so like, check it, don't just rawdog the pointer fr fr)
