NVME_MI_ADMIN_SECURITY_SEND(2)

💖 nvme_mi_admin_security_send — bestie's guide to yeeting a Security Send at a controller 💖

okay so real talk: this one is from the libnvme API manual, and it's literally just the glow-up edition of nvme_mi_admin_security_send(2). sit down, grab a boba, we're doing admin commands 🧚✨

---

✨ NAME ✨

nvme_mi_admin_security_send — bestie, this performs a Security Send command on a controller. that's the whole vibe 👑

---

🌸 SYNOPSIS 🌸

int nvme_mi_admin_security_send (nvme_mi_ctrl_t ctrl , struct
       nvme_security_send_args *args );

look at her. two args, one int, zero nonsense 💅

---

🎀 ARGUMENTS 🎀

• ctrl — the controller you're sending the command to. this is your main character, the one you're talking to 🫶
• args — the Security Send command arguments. all the little details of what you're actually asking for live in here ✨

---

🦋 DESCRIPTION 🦋

so what does she do, you ask? she performs a Security Send Admin command as specified by args. no cap 🧚

the response data gets stored in args->data, and — listen — that thing should be a buffer of args->data_len bytes. that's not optional bestie, that's the whole arrangement 🙈

once the command completes successfully, the resulting data length gets stored in args->data_len. so she writes back to you. communication, we love to see it 💖

⚠️ okay this part matters: Security Send data length should not be greater than 4096 bytes to comply with specification limits. 4096. that's the ceiling. do not test her. do not push past it. the spec said what it said 😭

See: struct nvme_get_log_args — go look, iykyk 📖

---

🌈 RETURN 🌈

she gives you back the nvme command status if a response was received (peep enum nvme_status_field for the whole menu of them) 🔥

or… -1 with errno set otherwise 💀 that's the "something went sideways" path, and honestly? we don't talk about her.
