xs_setup_local(9)

💅 xs_setup_local — like, the AF_LOCAL setup era

okay so bestie, we're deep in the sunrpc kernel API manual rn — this is the xs_setup_local(9) page, part of the Kernel API Manual, and it's honestly short but iconic. Let me walk you through it 🫶

---

✨ NAME ✨

xs_setup_local — set up transport to use an AF_LOCAL socket 🌸

it's giving "make the socket local", no cap.

---

✨ SYNOPSIS ✨

struct rpc_xprt * xs_setup_local (struct xprt_create *args );

like, that's the whole signature. she's a pointer-returning function, periodt 💅

---

✨ ARGUMENTS ✨

• args — the rpc transport creation arguments 🎀 literally the stuff you hand over so the transport knows how to be born.

---

✨ DESCRIPTION ✨

so AF_LOCAL is a "tpi_cots_ord" transport — and the way that it's just like TCP?? yeah. that's the whole vibe. lowkey identical energy, different address family ✨🔥
