💅 iw_cm_listen(9)

okay bestie, welcome to the Kernel API Manual ✨ this one's a little function with main character energy — it's literally just sitting there waiting for someone to slide into your DMs. No cap.

---

🌸 NAME 🌸

iw_cm_listen — lowkey the "open for business" button: listen for incoming connection requests on the specified IW CM id. 👑

---

🦋 SYNOPSIS 🦋

int iw_cm_listen (struct iw_cm_id *cm_id , int backlog );

---

🎀 ARGUMENTS 🎀

• cm_id — the IW CM identifier. that's your whole vibe, your whole identity, the thing that knows who you are 🫶
• backlog — the maximum number of outstanding un-accepted inbound listen requests to queue. think of it as your inbox limit: people can knock, but only this many can pile up unread before it gets awkward 😭

---

✨ DESCRIPTION ✨

so here's the tea ☕ — the source address and port number are specified in the IW CM identifier structure. that's it, that's the whole thing. the cm_id is where the address + port live, so the function doesn't need you to pass them separately. iconic behaviour honestly 💅
