💫 ctl_raae_count_show(9) 💫

okay bestie, so this is a page straight out of the Kernel API Manual, section 9 — and the star of the show is ctl_raae_count_show, aka controller raae count check. yes it's a real function name, no I can't make it sound less chaotic, just come with me 🫶

🌸 NAME 🌸

ctl_raae_count_show — controller raae count check. that's it, that's the whole vibe check 💅

---

✨ SYNOPSIS ✨

ssize_t ctl_raae_count_show (struct device *cdev , struct device_attribute *attr , char *buf );

look at her go, she's returning a ssize_t and taking three args, main character energy fr fr 👑

---

🎀 ARGUMENTS 🎀

• cdev — pointer to embedded class device. this is the one you actually care about, she's the whole point 🧚
• attr — device attribute (unused). literally not invited to the party, ignore her 🙈
• buf — the buffer returned. this is where the output goes, keep it safe bestie 🍓

🦋 DESCRIPTION 🦋

so this one is a sysfs 'read-only' shost attribute. that's the whole description, short and iconic — read-only, no writing, don't even try it, periodt ⭐

ngl it's giving "small function, big responsibilities" — it's read-only so you're not out here mutating anything, you're just reading 💜
