LIBNVME_SUBSYSTEM_GET_IOPOLICY-LIBNVME3(2)

💖 libnvme API manual: libnvme_subs...get_iopolicy(9) 💖

okay bestie, welcome to the libnvme API manual — this page is libnvme_subs...get_iopolicy(9), and we're talking about libnvme_subsystem_get_iopolicy. It's literally giving "get the iopolicy" energy, and honestly? iconic. 💅

✨ NAME ✨

libnvme_subsystem_get_iopolicy — get iopolicy. That's the whole vibe. 🎀

🦋 SYNOPSIS 🦋

int libnvme_subsystem_get_iopolicy (const struct libnvme_subsystem *p ,
const char **iopolicy , const char *dflt );

🎀 ARGUMENTS 🎀

• p — the struct libnvme_subsystem instance to query. This is the subsystem bestie you're asking about. 🫶
• iopolicy — where to store the value on success. Yes, it's a const char **; she's a pointer-to-pointer, periodt.
• dflt — value to store in iopolicy on failure. The fallback bestie. 🍓

💅 RETURN 💅

• 0 on success. Slay. ✅
• -ENOENT if the attribute does not exist. Like, it's not there, no cap. 😭
• or a negative errno on failure. Not the vibe, but that's what it returns. 💀
