rpc_get_scope_id(9)

💅 rpc_get_scope_id(9) — the Kernel API Manual files

okay so bestie, welcome to the rpc_get_scope_id page, straight out of the Kernel API Manual (section 9, kernel-space girlies only 💖). it's a tiny one, but it eats, so let's get into it.

---

✨ NAME ✨

rpc_get_scope_id — literally just returns the scopeid for a given sockaddr. that's the whole job. she's focused, she's employed 🎀

---

🌸 SYNOPSIS 🌸

u32 rpc_get_scope_id (const struct sockaddr *sa );

yes, that's the entire signature. no cap, that's it. u32 in, u32 out — well, const struct sockaddr * in, u32 out. iykyk 💅

---

🦋 ARGUMENTS 🦋

• sa — the sockaddr you're pulling the scopeid out of. that's the source of truth, the main character of this whole function fr fr.

---

💜 DESCRIPTION 💜

so here's the tea ☕ — rpc_get_scope_id returns the value of the sin6_scope_id for AF_INET6 addrs. and if the address isn't an AF_INET6 address? it gives you 0. simple as that. zero drama, zero extra steps ✨

quick vibe check to remember: AF_INET6 → real sin6_scope_id value. anything else → 0. periodt.

👑 SEE ALSO 👑

• the kernel file ./include/linux/sunrpc/addr.h — go read it, it's giving source material 🫶
• rpc_cmp_addr(9)
• rpc_cmp_addr_port(9)
• rpc_copy_addr(9)

they're all in the same friend group, obviously 🌈

that's the whole page, bestie — short, sweet, and lowkey iconic 💀✨
