wdt_temp_open(9)

💅 wdt_temp_open(9) — like, the manual page, bestie 🎀

okay so this is wdt_temp_open from section 9 of the Kernel API Manual, and yes she's a kernel-space girlie ✨ so let's get into it.

---

🌸 NAME 🌸

wdt_temp_open — (no blurb, she's mysterious, the original literally leaves it blank and we respect that 🙈)

---

✨ SYNOPSIS ✨

int wdt_temp_open (struct inode *inode , struct file *file );

periodt. that's the whole signature. copy it exactly, no cap 🫶

---

🦋 ARGUMENTS 🦋

• inode — the inode of the device 👑 that's it, that's the descriptor of the actual device node you're messing with.
• file — the file handle to the device 💖 the one you got handed when someone opened it.

---

💀 DESCRIPTION 💀

The temperature device has been opened. that's literally the entire description, bestie — she said "task completed, no notes" and logged off 😭💅

lowkey iconic of her to give us one (1) sentence and dip. but fr fr that's the whole vibe: this is the open handler, and its job is to notice that the temperature device just got opened. nothing more to report.
