lsm_disk_rpm_get(3)

💖 lsm_disk_rpm_get(3) 💖

okay bestie, so this one lives in the Libstoragemgmt C API Manual and it's literally the cutest little function — it just tells you how fast your disk is spinning. that's it. that's the whole job. 🌀

---

✨ NAME ✨

lsm_disk_rpm_get — retrieves the rotation speed for the disk.

like... the RPM. revolutions per minute. the spin rate. the whole vibe of how fast it's twirling. 🎀

---

✨ SYNOPSIS ✨

int32_t lsm_disk_rpm_get (lsm_disk *d);

---

✨ ARGUMENTS ✨

• d — the disk you want the rotation speed for. that's your girl. hand her over. 🫶

---

✨ VERSION ✨

1.3 — yes, this has been iconic since 1.3, no notes. 💅

---

✨ DESCRIPTION ✨

so basically, this function retrieves the disk rotation speed — measured in revolutions per minute, aka RPM. that's the number of full spins per minute. very demure, very rotational. 🌸

---

✨ CAPABILITY ✨

LSM_CAP_DISK_RPM

that's the capability flag gating this whole thing. if the plugin doesn't have it, we're not getting a number, periodt. 👑

---

✨ RETURN ✨

returns an int32_t, and it's the disk rotation speed. here's the full rundown of what that number could actually be, and no, we are not skipping any of them:

• >1 — a normal rotational disk. she spins. she's a hard drive doing hard drive things. 🔥
• LSM_DISK_RPM_NO_SUPPORT — the plugin just doesn't support this. not our fault, not your fault. 💀
• LSM_DISK_RPM_NON_ROTATING_MEDIUM — non-rotating medium (e.g., SSD). no spinning, no moving parts, just silent main character energy. ✨
• LSM_DISK_RPM_ROTATING_UNKNOWN_SPEED — rotational disk, but the speed is unknown. she's spinning and she's keeping secrets. 🙈
• LSM_DISK_RPM_UNKNOWN — bug, or invalid argument, or just not supported. the chaotic one. 🦋

ngl bestie, watch out for that last one — LSM_DISK_RPM_UNKNOWN can straight up mean a bug, an invalid argument, or unsupported. it's the "something's off but we're not telling you what" of return values. 😭

that's the whole page, fr fr. stay spun, stay slay. 🌈💜
