version_get(9)

💅 version_get(9) — like, the Kernel API Manual page for version_get

okay so bestie, we're deep in the Kernel API Manual today (section 9, kernel-land, no cap) and the function we're stanning is literally called version_get. Yes girl, it's exactly what it sounds like ✨

---

🌸 NAME 🌸

version_get — the command to get the revision of the SCMI entity 🎀

---

✨ SYNOPSIS ✨

int version_get (const struct scmi_protocol_handle *ph , u32 *version );

that's the whole vibe. two args, one int coming back atcha 💖

---

🦋 ARGUMENTS 🦋

• ph — pointer to the SCMI protocol handle. like, the little handle bestie that tells you which protocol we're even talking about 🫶
• version — holds the returned version of the protocol. this is where the answer gets dropped off, so make sure it's pointing somewhere real 💅

---

💜 DESCRIPTION 💜

Updates the SCMI information in the internal data structure. that's it, that's the whole glow-up — it refreshes the info inside the internal data structure. main character behaviour, tbh 🌟

---

🎀 RETURN 🎀

0 if all went fine 🔥 — otherwise it returns the appropriate error, and you're gonna have to deal with that yourself, sorry babe 😭
