nvme_init_g...host_mem_buf(9)

💅 nvme_init_g...host_mem_buf(9) 💅

okay bestie so this is a page from the libnvme API manual, section 9 — and the title got cut off in the header because apparently even manpage headers have a character limit 🙈 The full name is nvme_init_get_features_host_mem_buf, and no, that is not a typo, it's just genuinely that long. She's verbose. She's iconic. Periodt.

✨ NAME ✨

nvme_init_get_features_host_mem_buf — sets up (initializes) the passthru command for Get Features – Host Memory Buffer. That's the whole vibe. It's a setup girlie, not a doer. 💅

---

🌸 SYNOPSIS 🌸

void nvme_init_get_features_host_mem_buf (struct libnvme_passthru_cmd *cmd,
                                          enum nvme_get_features_sel sel,
                                          struct nvme_host_mem_buf_attrs *attrs);

Note the void — she gives nothing back, and honestly? Respect. 🫶

🎀 ARGUMENTS 🎀

• cmd — the passthru command you're gonna use. This is the one getting prepped and primed, she's the main character here 👑
• sel — picks which type of attribute to return, see enum nvme_get_features_sel for the menu of options. Choose wisely bestie 🦋
• attrs — the buffer where the returned Host Memory Buffer Attributes land. Like an empty little basket you hand over and she fills it up 🧺✨

🌈 DESCRIPTION 🌈

So what does it actually do? It initializes the passthru command buffer for the Get Features command, with the FID value set to NVME_FEAT_FID_HOST_MEM_BUF. That's it. That's the whole job. Lowkey iconic for how specific it is 💀

Like, she's not out here doing the Get Features call herself — she's just making sure cmd is dressed and ready with the right FID before you go send it. Prep work. Supportive bestie energy. Fr fr. 💖

Heads up: it's a void function and it only initializes the buffer — the actual command doesn't go anywhere until you send it yourself. Don't be out here expecting magic ✨

and that's the whole page, no cap 🍓

sign-off time 🎀✨ — this lil beauty lives in the libnvme API manual, dated October 2026, and the footer's a whole mood: nvme_init_get_features_host_nvme_init_g...host_mem_buf(9) (yes the title gets squished again, she's just too long for the footer, we love her anyway 💜). bye bestie, go init some buffers 🦋
