srpt_mad_recv_handler(9)

💅 srpt_mad_recv_handler(9) — the MAD reception callback 🎀

okay so bestie, welcome to the Kernel API Manual entry for srpt_mad_recv_handler — yes it's a (9) page, yes it's kernel-internals territory, and yes you're gonna slay it. this is the callback that fires when a MAD shows up. that's it, that's the vibe ✨

---

🌸 NAME 🌸

srpt_mad_recv_handler — the MAD reception callback function, aka the little function that gets pinged when someone slides a MAD into your inbox 💌

---

🦋 SYNOPSIS 🦋

void srpt_mad_recv_handler (struct ib_mad_agent *mad_agent , struct
       ib_mad_send_buf *send_buf , struct ib_mad_recv_wc *mad_wc );

so it returns void (no receipts, no return value, she just does the thing) and it takes three args. three! a whole trio. let's meet them 👇

---

💖 ARGUMENTS 💖

• mad_agent — this is the return value of ib_register_mad_agent. yes, literally the thing that function handed back to you. hand it right back here, that's the whole gig 🫶
• send_buf — not used. that's it. not used. she's invited to the party but she's not dancing 🙈
• mad_wc — the work completion reporting that a MAD has been received. this is the actual "omg something arrived" notification, the main character of the parameter list 👑
