🦋 rio_query_mport(9) 🦋

okay so this one's from the Kernel API Manual and it's literally the tiniest little function ever — but she's important, so let's give her the moment she deserves 💅

✨ NAME ✨

rio_query_mport — query mport device attributes 🎀

---

🌸 SYNOPSIS 🌸

int rio_query_mport (struct rio_mport *port , struct rio_mport_attr
*mport_attr );

🫶 ARGUMENTS 🫶

• port — the mport device you're querying. that's the one, bestie 🎯
• mport_attr — the mport attributes data structure. this is where the tea gets poured ☕

---

💖 DESCRIPTION 💖

so what does she do?? she returns the attributes of the specified mport, and she does it through the pointer to the attributes data structure. that's it. that's the whole vibe. you hand her a mport_attr and she fills it in. iconic, no notes 🌟

ngl it's giving "small function, big responsibility" — main character energy fr fr 👑
