libnvme_ns_read(9)

💖 libnvme_ns_read — bestie's guide to reading from a namespace 💖

okay so this is a page straight outta the libnvme API manual (yes, the libnvme API manual, that's the whole vibe, section 9, we love a numbered section) and it's literally just one function that reads stuff off a namespace. short page, immaculate energy, let's go 🫶

✨ NAME ✨

libnvme_ns_read — Read from a namespace

no cap, that's it, that's the whole job description. it reads. from a namespace. iconic behavior honestly 💅

---

🌸 SYNOPSIS 🌸

int libnvme_ns_read (struct libnvme_ns *n , void *buf , off_t offset ,
       size_t count );

look at her. four arguments, returns an int, zero drama. she ate 🔥

---

🎀 ARGUMENTS 🎀

• n — the Namespace instance ✨ this is your main character, the namespace you're reading from, a struct libnvme_ns *, please treat her right 💜
• buf — the Buffer into which the data will be transferred 🦋 like, the data literally goes in here. this is the destination. the home. the spot where your bytes land 🏠
• offset — the LBA offset of n 📍 iykyk, LBA = logical block address, and this is where in the namespace you're starting from. it's an off_t, so mind your types, bestie 🧚
• count — the Number of sectors in buf 🍓 careful with the units here, okay? it's not bytes, it's sectors — the number of sectors in buf. do not come for me about this, the page says sectors and I'm saying sectors 🙈

---

⭐ RETURN ⭐

Number of sectors read on success, or -1 on error 😭

so like... check the return value. if you get -1, something went wrong, and the function will not be telling you what. that's a you problem to debug, bestie 💀

and that's the whole page, honestly. short and sweet, very demure, very mindful 🎀 this was the libnvme_ns_read page (libnvme_ns_read(9), in case you forgot already) from the libnvme API manual, dated October 2026 — see you in the next manpage, mwah 😘💖🌈
