💅 nlmsvc_proc_null — the Kernel API Manual moment

okay so bestie, welcome to nlmsvc_proc_null from the Kernel API Manual — yes that's the manual name, we're not gatekeeping it, it's right there ✨

🌸 NAME 🌸

nlmsvc_proc_null — literally just NULL: Test for presence of service. that's the whole vibe. it's the "u up?" text of RPC calls, no cap 🫶

✨ SYNOPSIS ✨

__be32 nlmsvc_proc_null (struct svc_rqst *rqstp );

that's it. one argument. she's low maintenance, she's iconic 💅

🎀 ARGUMENTS 🎀

  • rqstp — the RPC transaction context. think of it as the little purse she carries around with all the context she needs, okurrr 👜

🔥 RETURN 🔥

  • rpc_success — RPC executed successfully. she ate and left no crumbs, periodt 👑

🦋 DESCRIPTION 🦋

RPC synopsis, verbatim, because we don't play about accuracy:

void NLM_NULL(void) = 0;

so it's giving "hello? are u there?" energy — the test for presence of service, and nothing more. ngl that's the entire bit 🧚
