cpufreq_get_cur_state(9)

💅 cpufreq_get_cur_state(9) ✨

okay bestie, so this is a page from the Kernel API Manual — yes, the kernel, yes, the big one — and it's all about cpufreq_get_cur_state. It's a callback function that gets the current cooling state. that's literally the whole vibe. 🧊

---

🎀 SYNOPSIS 🎀

int cpufreq_get_cur_state (struct thermal_cooling_device *cdev ,
unsigned long *state );

two arguments, one int coming back at you. that's the whole signature, no cap. ✨

---

🌸 ARGUMENTS 🌸

• cdev — the thermal cooling device pointer. like, the actual device you're asking about. 🫶
• state — you fill this variable with the current cooling state. it's an unsigned long *, so yes, you're writing through a pointer, bestie, be normal about it. ✍️

---

💖 DESCRIPTION 💖

so this is the callback for the thermal cooling device — its whole job is to hand back the cpufreq current cooling state. the thermal side knocks, this function answers. that's the gig. it's giving "reliable friend who always picks up the phone." 👑

---

🔥 RETURN 🔥

0 on success. and like — this function doesn't fail. at all. literally cannot flop. returns 0, done, periodt. 💀✨

ngl this one's short and sweet — no warnings, no gotchas, no deprecated anything. just a chill little callback doing its one job. main character energy, honestly. 🎀
