NVME_MI_ADMIN_GET_LOG_CREATE_TELEMETRY_HOST_MCDA(2)

✨ nvme_mi_admin_get_log_create_telemetry_host_mcda ✨

okay bestie so this is a page from the libnvme API manual (yes, section 2, the syscall-slash-library girlies) and it's all about one little function that makes a host telemetry log. it's giving "I need receipts and I need them telemetry-shaped." 💅

---

🎀 NAME 🎀

nvme_mi_admin_get_log_create_telemetry_host_mcda — Create host telemetry log ✨

---

🦋 SYNOPSIS 🦋

int nvme_mi_admin_get_log_create_telemetry_host_mcda (nvme_mi_ctrl_t
ctrl , enum nvme_telemetry_da mcda , struct nvme_telemetry_log *log );

---

🌸 ARGUMENTS 🌸

• ctrl — the Controller to query. this is the lil guy you're asking, bestie. 👑
• mcda — Maximum Created Data Area. yes that's the whole description, it's a mystery and we respect it. 🙈
• log — Userspace address of the log payload. that's where the good stuff lands. 🍓

---

💖 RETURN 💖

so here's the tea:

• if a response came back, you get the nvme command status</span> (go peek at enum nvme_status_field for the deets)
• otherwise you get -1 with errno set 😭

ngl, -1 with errno set is the "it's not me, it's the environment" of return values. no cap.
