attr_current_value_show(9)

✨ attr_current_value_show(9) ✨

okay bestie, welcome to the Kernel API Manual section 9 page for attr_current_value_show — yes it's a mouthful, no I won't be shortening it, we respect the full name in this house 💅

---

🌸 NAME 🌸

attr_current_value_show — literally just "get the current value of the given attribute", that's it, that's the whole gig 🎀

---

🦋 SYNOPSIS 🦋

ssize_t attr_current_value_show (struct kobject *kobj , struct
kobj_attribute *kattr , char *buf , struct tunable_attr_01 *tunable_attr
);

---

💖 ARGUMENTS 💖

• kobj — pointer to the driver object 🫶
• kattr — pointer to the attribute that's calling this function, like hi bestie you rang?
• buf — the buffer we're gonna write to ✍️
• tunable_attr — the attribute that's, yep, being read 👑

---

⭐ DESCRIPTION ⭐

So what it does: it retrieves the value of the given attribute for the current smartfan profile. And where does that current smartfan profile come from? The lenovo-wmi-gamezone driver, obviously 💁‍♀️

This function is intentionally generic — like, main character energy but reusable energy — so it can be called from any integer attribute's "_show" function. no cap, any of them 🌈

And if the WMI is success, the sysfs attribute gets notified 📣✨

---

🔥 RETURN 🔥

Either the number of characters written to buf, or an error code. that's the vibe check 😭
