💅 mei_cl_mtu — a Kernel API Manual moment 🎀

okay so bestie, welcome to the mei_cl_mtu(9) page, which lives in the Kernel API Manual (yes, that manual) — and honestly? it's a short one, but it's lowkey important, so let's get into it ✨

---

🌸 NAME 🌸

mei_cl_mtu — the max message size that a client can send and receive 🫶 literally the "how big can this text bubble be" of the MEI world, no cap.

---

🦋 SYNOPSIS 🦋

size_t mei_cl_mtu (const struct mei_cl *cl );

that's it, that's the whole vibe check 💖 one function, one argument, one size_t coming back at you.

---

✨ ARGUMENTS ✨

• cl — the host client 👑 (yes, the type is const struct mei_cl *, we're being respectful, nobody's editing anybody today)

---

💜 RETURN 💜

it hands you back the mtu, or 0 if the client is not connected 😭 — so if you get a zero, that's your sign the client is basically ghosting you, fr fr. not connected = no mtu, periodt.

---
