nsm_monitor(9)

💖 nsm_monitor(9) — Kernel API Manual, section 9, bestie edition 💖

okay so like, imagine your kernel is a main character who might ~dramatically~ reboot at any moment. this little function is how it makes sure somebody remembers to text the group chat about it. it's giving responsible queen energy, ngl. 👑

✨ SYNOPSIS ✨

int nsm_monitor (const struct nlm_host *host );

🫶 ARGUMENTS 🫶

• host — pointer to the nlm_host of the peer we want to notify. that's it. that's the whole vibe. 💅

🌸 DESCRIPTION 🌸

okay so here's the tea: if this peer isn't already being monitored, nsm_monitor sends an upcall to the local rpc.statd so it records the name/address of the peer to notify in case we reboot. literally just making sure the receipts are saved before anything chaotic happens. 🧚✨

and the return value? she's simple:

• returns zero if the peer is monitored by the local rpc.statd — slay, we're covered 💖
• otherwise you get a negative errno value — not the vibe, but at least it's honest 😭

no cap, don't lose the errno — negative numbers are the whole point here, bestie.
