💅 rio_request_inb_pwrite(9) — Kernel API Manual glow-up ✨

🎀 NAME 🎀

rio_request_inb_pwrite — request inbound port-write message service for specific RapidIO device. No cap, that's the whole name drop 💖

---

🌸 SYNOPSIS 🌸

okay bestie, here's the signature exactly as it appears, do not come for me:

int rio_request_inb_pwrite (struct rio_dev *rdev , int (*pwcback)(struct
       rio_dev *rdev, union rio_pw_msg *msg, int step) );

---

🦋 ARGUMENTS 🦋

• rdev — the RIO device to which you register the inbound port-write callback routine. Main character device energy, honestly.
• pwcback — the callback routine to execute when a port-write is received. It's giving "call me when the message lands" 📞✨

---

✨ DESCRIPTION ✨

So the vibe is literally this: it binds a port-write callback function to the RapidIO device. That's the whole tea ☕

And if the request has been satisfied, it returns 0. Periodt 💅
