libnvme(2)

✨ NAME ✨

okay bestie, we're in the libnvme manual (that's libnvme(2) for the section-heading girlies) and today's main character is struct nvme_format_nvm_start_event — the Format NVM Start Event Data 💅

like, it's literally the little data blob that shows up when a Format NVM operation starts. it's giving "the opening scene before the glow-up montage" ✨

---

🦋 SYNOPSIS 🦋

no cap, here's the whole thing, exactly as it lives in the header:

struct nvme_format_nvm_start_event {
    __le32 nsid;
    __u8 fna;
    __u8 rsvd5[3];
    __le32 format_nvm_cdw10;
 };

that's it. that's the struct. she's small but she's iconic 🎀

🌸 Members 🌸

bestie, let's do a little vibe check on every single field, one by one, no skipping 🙈

• nsid — the Namespace Identifier 🦋 it's literally telling you which namespace we're talking about. main character energy for the namespace.
• fna — the Format NVM Attributes ✨ the little attributes byte that rides along with the format. she's got opinions.
• rsvd5 — Reserved 💤 not me paying attention to the reserved bytes... they're just sitting there, three of them (rsvd5[3], to be exact), being reserved. respectful. quiet. slaying in their own reserved way 🫶
• format_nvm_cdw10 — Format NVM CDW10 🔥 the command dword 10 that goes with the Format NVM command. yep, it's got a whole dword and she's using it.

---

⚠️ reminder bestie: rsvd5[3] is reserved, so don't be out here writing your own little secrets into it. reserved means reserved, periodt 💀
