rpc_call_async(9)

✨ rpc_call_async(9) ✨

okay so bestie, welcome to the rpc_call_async page from the Kernel API Manual 💅 this is a kernel function and it does one thing and it does it asynchronously, which is basically main-character energy for syscalls — it does NOT wait around for the reply like some needy sync function, it just fires the call and dips 🦋

---

🌸 NAME 🌸

rpc_call_async — Perform an asynchronous RPC call 🔥

like, the whole vibe is right there in the name, iykyk

---

🎀 SYNOPSIS 🎀

int rpc_call_async (struct rpc_clnt *clnt , const struct rpc_message
*msg , int flags , const struct rpc_call_ops *tk_ops , void *data );

it gives back an int, and it takes five things — every single one of them is listed below, no skips, we don't do that here 🫶

---

💖 ARGUMENTS 💖

• clnt — pointer to RPC client 💫 like, the client struct you're calling through. no client, no call, periodt.
• msg — RPC call parameters ✨ the whole description of the call lives in here.
• flags — RPC call flags 🎀 little behaviour switches, exactly as advertised.
• tk_ops — RPC call ops 🧚 the ops struct, which is where the callback situation lives (tk is giving "task", and honestly that tracks).
• data — user call data 💜 your own pointer, your own business, it gets handed back to you.
