💖 lsm_local_disk_ident_led_on — bestie edition 💖

✨ NAME ✨

lsm_local_disk_ident_led_on — turn on the disk identification LED. yes bestie, the little blinky light. the main character of the server rack. 💡

---

🌸 SYNOPSIS 🌸

int lsm_local_disk_ident_led_on (const char *disk_path, lsm_error
**lsm_err);

---

🎀 ARGUMENTS 🎀

• disk_path — a String. it's the path of the disk path (yes, that's what the docs say, we don't make the rules 💅), for example "/dev/sdb".
• lsm_err — output pointer of lsm_error. the error message could be retrieved via lsm_error_message_get. and the memory should be freed by lsm_error_free. don't forget to free it, bestie, we are not leaking in this house. 🫶

🦋 VERSION 🦋

1.3 — she's been here a minute, she's established, she's iconic. 👑

---

⭐ DESCRIPTION ⭐

Turn on the identification LED for the specified disk. that's it, that's the whole vibe. ✨

it requires read and write access to the specified disk path. so if you're running as some random unprivileged little guy, she's gonna say no. 🙈

---

🔥 RETURN 🔥

it hands you back an error code, as enumerated by lsm_error_number, and here's the full rundown, no skips:

• LSM_ERR_OK — on success. slay. 💖
• LSM_ERR_INVALID_ARGUMENT — when any argument is NULL.
• LSM_ERR_NO_MEMORY — when no memory. 😭
• LSM_ERR_LIB_BUG — when something unexpected happens. 💀
• LSM_ERR_NOT_FOUND_DISK — when the provided disk path is not found.
• LSM_ERR_PERMISSION_DENIED — insufficient permission to access the provided disk path.
• LSM_ERR_NO_SUPPORT — action is not supported. it's giving "we don't do that here."

---

and that's the whole page, bestie. go forth and light up those disks. 🌈
