libnvme(9)

💅 libnvme(9) — the API manual, bestie edition ✨

Okay so welcome to libnvme, section 9 of your manual, and today's main character is one very specific little enum. Buckle up 🎀

---

✨ NAME ✨

enum nvme_zns_mgmt_send_cqe_dw0 — literally the Zone Management Send - Completion Queue Entry Dword 0. That's it, that's the whole vibe. It's giving "small but crucial" ngl 💖

---

🦋 SYNOPSIS 🦋

enum nvme_zns_mgmt_send_cqe_dw0 {
    NVME_ZNS_MGMT_SEND_CQE_ZCC_SHIFT ,
    NVME_ZNS_MGMT_SEND_CQE_ZCC_MASK

};

Copy it exactly like that, no cap. Two constants, that's the whole enum, and yes the trailing comma situation is what it is 🙈

🌸 Constants 🌸

So these are the two members of the enum, and here's the tea on each one:

• NVME_ZNS_MGMT_SEND_CQE_ZCC_SHIFT — the shift amount you need to get Zone Capacity Changed (ZCC) out of there. It's the "how far do I slide over" number ✨
• NVME_ZNS_MGMT_SEND_CQE_ZCC_MASK — the mask you use to get ZCC. Slap this on and you're extracting the ZCC bits, slay 💅

Pro tip from me to you: shift and mask, always a duo. They're a matched set, icons only 👑

Okay that's genuinely the whole page, and honestly? Short, sweet, and extremely efficient. Obsessed 🫶

Sign-off time, cute edition: this page is from October 2026, it's the enum nvme_zns_mgmt_send_cqe_dw0 entry, and it lives in libnvme(9). Byeee, go read the ZCC bits 💜🌈⭐
