irdma_reject(9)

💅 irdma_reject(9) — Kernel API Manual

okay so bestie, welcome to the irdma_reject page ✨ this one lives in the Kernel API Manual, section 9, and it's honestly a shortie but she's iconic. Buckle in 🎀

---

🌸 NAME 🌸

irdma_reject — the registered callback you fire when a connection needs to be rejected. like, not ghosted, actively declined. no cap 💅

---

✨ SYNOPSIS ✨

int irdma_reject (struct iw_cm_id *cm_id , const void *pdata , u8
pdata_len );

that's the whole vibe — one function, three args, returns an int. slay 🫶

---

🦋 ARGUMENTS 🦋

• cm_id — the cm info for the passive connection. this is the one getting the "it's not you, it's me" treatment 🙈
• pdata — the private data you wanna send along with the rejection. yes, you can leave a little note 💌
• pdata_len — how long that private data is. keep it honest, u8 is a tiny little range 👑
