nvme_resv_report(2)

💖 nvme_resv_report — like, the whole tea on your namespace reservations 💖

okay bestie, welcome to the libnvme API manual page for nvme_resv_report. pull up a chair, grab a boba, we're doing syscalls today 🧋✨

---

🌸 NAME 🌸

nvme_resv_report — send an nvme reservation report, no cap 💅

---

✨ SYNOPSIS ✨

int nvme_resv_report (struct nvme_resv_report_args *args );

---

🎀 ARGUMENTS 🎀

• args — it's a struct nvme_resv_report_args argument structure. yes, that's the whole vibe. she holds the args, you hold the vibes 🫶

---

🦋 DESCRIPTION 🦋

so what does she actually do? she returns a Reservation Status data structure to memory, and that structure describes the registration and reservation status of a namespace. it's giving "receipts for your namespace" honestly 👑

and if you wanna know the exact shape of the thing that comes back, go look at the definition for the returned structure, struct nvme_reservation_status — that's where all the details live, iykyk. don't be out here guessing at fields when the struct definition is literally right there, bestie 😭

---

🔥 RETURN 🔥

here's the part where you gotta pay attention fr fr:

• if a response was received, you get the nvme command status (peep enum nvme_status_field for the full menu of what those mean 🌈)
• otherwise? you get -1, and errno is set. classic. lowkey rude but iconic 💀

---

heads up bestie: a -1 means check errno, not "shrug and move on". the error will tell you what happened, so read it 💖

---

okay that's the whole page, slay, you're basically an NVMe reservation expert now 👑
