route_register_is_valid(9)

💅 route_register_is_valid(9) 💅

okay bestie, welcome to the Kernel API Manual — this one's a lil function called route_register_is_valid, and it's giving "short and mysterious" energy ngl. Let's get into it 🫶

---

✨ NAME ✨

route_register_is_valid — determines whether the register value for the specified route destination on the specified device is valid.

that's it. that's the whole vibe check. no notes. 💖

---

🌸 SYNOPSIS 🌸

bool route_register_is_valid (const u8 src_sel_reg_value , const int
dest , const struct ni_route_tables *tables );

she returns a bool, she takes three args, she's on her main character grind 👑

---

🎀 ARGUMENTS 🎀

okay so here's the thing, and I need you to sit down for this one 😭 — the original docs did NOT come through with the descriptions. like at all. every single one of these literally just says -- undescribed --. so:

• src_sel_reg_value — -- undescribed -- 💀
• dest — -- undescribed -- 💀
• tables — -- undescribed -- 💀

that's it. that's all the info we got, fr fr. no cap, I'm not gonna make something up and lie to you, bestie — that would be so not slay of me. what I can tell you is exactly what's in the synopsis: it's a const u8, a const int, and a const struct ni_route_tables *. that's a real thing we know 💅

heads up bestie: three args and zero descriptions means the source file is genuinely the main character here. if you need the actual semantics, <pink>ni_routes.h</pink> is right there. iykyk ✨
