💅 rpc_call_sync(9) — Kernel API Manual ✨

okay so bestie, welcome to the rpc_call_sync page 💖 this is one of those kernel API manual pages (from the Kernel API Manual set, the (9) section, iykyk) and it's honestly short and sweet. let's get into it 🫶

🦋 SYNOPSIS 🦋

int rpc_call_sync (struct rpc_clnt *clnt , const struct rpc_message *msg
, int flags );

that's the whole signature, copy it exactly bestie, don't be out here retyping it from memory 😭

🎀 ARGUMENTS 🎀

• clnt — pointer to RPC client 🫶 literally just a pointer to the RPC client, that's it, that's the whole thing
• msg — RPC call parameters 📨 the parameters for this RPC call go in here
• flags — RPC call flags 🚩 the flags for the RPC call. flags. yes. they exist, they're flags 💅
