✨ nvme_get_log_predictable_lat_nvmset(2) ✨

okay bestie, welcome to the libnvme API manual 💖 this one's called nvme_get_log_predictable_lat_nvmset, and it's literally the Predictable Latency Per NVM Set getter. yes, that's a mouthful, we love her anyway 🫶

---

🎀 NAME 🎀

nvme_get_log_predictable_lat_nvmset — the one that grabs you the Predictable Latency Per NVM Set log. slay. that's the whole job. no cap. 💅

---

🌸 SYNOPSIS 🌸

int nvme_get_log_predictable_lat_nvmset (int fd , __u16 nvmsetid ,
       struct nvme_nvmset_predictable_lat_log *log );

like… three args, one call, and you're living your best life. it's giving function signature ✨

---

🦋 ARGUMENTS 🦋

• fd — the file descriptor of your nvme device, bestie. that's your lil doorway to the drive, your main character entry point 👑
• nvmsetid — the NVM set id. which NVM set are we talking about?? you tell her, because she does not guess. it's a __u16, so keep it in range fr fr
• log — the user address where the predictable latency log gets stored 🍓 this is a struct nvme_nvmset_predictable_lat_log *, so like… you bring the memory, she fills it. iconic teamwork

---

🌈 RETURN 🌈

so here's the vibe check on what comes back:

• if a response was received, you get the nvme command status (peep enum nvme_status_field for the full tea, iykyk 💜)
• otherwise?? you get -1 and errno gets set. not the slay ending but that's how it goes 😭

lowkey important: check that errno, bestie. -1 by itself is not the whole story 💀

and that's the whole page, no filler, every detail intact, periodt 💅
