arm_cpuidle_get_ops(9)

💅 arm_cpuidle_get_ops — like, the whole vibe

okay so bestie, welcome to the Kernel API Manual page for arm_cpuidle_get_ops(9) — yes the section number is 9, yes we're in kernel-land, no you can't leave 🫶

---

✨ NAME ✨

arm_cpuidle_get_ops — bestie's job is literally just: find a registered cpuidle_ops by name. that's it. that's the whole arc. 🎀

---

🌸 SYNOPSIS 🌸

const struct cpuidle_ops * arm_cpuidle_get_ops (const char *method );

like yes, it returns a pointer, yes it's const, we love a read-only king 👑

---

🦋 ARGUMENTS 🦋

• method — the method name. that's the string you're out here searching for, no cap 🍓

---

💖 DESCRIPTION 💖

so the way this works is genuinely iconic: it goes searching through the __cpuidle_method_of_table array looking for the cpuidle ops that match the method name you handed it. like a vibe check but for method names ✨

and what do you get back? a struct cpuidle_ops pointer. slay. 💅

but — and this is the part where you go 🫶 — if it doesn't find anything, you get NULL. not a warning, not a little note, just NULL. so please, for the love of everything, check your return value. main character energy includes error handling fr fr 😭
