rio_get_input_status(9)

💅 rio_get_input_status — a Kernel API Manual moment (section 9, bestie)

okay so picture this: you're deep in the RapidIO corner of the kernel, in the Kernel API Manual (section 9, very demure, very minding-its-own-business), and you need to poke a link partner and ask "hey girl, what's your input status?" That's literally this function. It sends a Link-Request/Input-Status control symbol and hands you back the link-response if requested. Slay. 🦋

✨ NAME ✨

rio_get_input_status — sends a Link-Request/Input-Status control symbol and returns the link-response (if requested). That's it, that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

int rio_get_input_status (struct rio_dev *rdev , int pnum , u32 *lnkresp );

Three arguments, one int back. Short, iconic, no notes. 🎀

---

🧚 ARGUMENTS 🧚

• rdev — the RIO device that's gonna issue the Input-status command. This is the main character of the operation, the one holding the microphone. 🎤
• pnum — the device port number to issue the command on. Like picking which door in the hallway you're knocking on. 🚪
• lnkresp — the response from a link partner. This is where the answer lands, so bestie, do give it somewhere to live. 🫶
