🌸 iwl_mei_is_connected (9) 💅

okay so real talk, this page lives in the Kernel API Manual, and honestly? it's a tiny little function with big "am i talking to my bestie right now" energy. let's get into it 🫶

---

✨ NAME ✨

iwl_mei_is_connected — is the connection to the CSME firmware established?

literally just: are we connected to the CSME firmware or not. that's the whole vibe check 🦋

---

🌈 SYNOPSIS 🌈

bool iwl_mei_is_connected (void );

no cap, that's the entire signature. it returns a bool, and it takes void. iconic minimalism 💅

---

🎀 ARGUMENTS 🎀

• void — no arguments. none. zero. the function said "i don't need anything from you bestie" 😭

---

⭐ RETURN ⭐

true if we have a SAP connection.

so like, if it hands you back true, that means a SAP connection is up and running. if not... well, you already know 🙈
