sht15_status_show(9)

💅 sht15_status_show(9) — from the Kernel API Manual, bestie 🫶

okay so like. this is a page straight out of the Kernel API Manual and it's all about one tiny little sysfs show function. it's not glamorous, but it is iconic, and we're gonna read it together. no cap. ✨

---

🌸 NAME 🌸

sht15_status_show — literally just here to show status information in sysfs. that's it. that's the whole job. 💖

---

✨ SYNOPSIS ✨

ssize_t sht15_status_show (struct device *dev , struct device_attribute
*attr , char *buf );

---

🎀 ARGUMENTS 🎀

• dev — the device. yeah. that one. 🦋
• attr — the device attribute. also exactly what it sounds like, bestie.
• buf — the sysfs buffer where the information gets written to. this is where the magic (the bytes) actually land. 🌈

---

💜 DESCRIPTION 💜

so the kernel goes ahead and calls this whenever someone reads from one of these sysfs attributes:

• temp1_fault
• humidity1_fault
• heater_enable

and then it returns the number of bytes it wrote into the buffer — or a negative errno if something went wrong. 😭 lowkey simple, highkey essential. periodt. 💅
