sht21_humidity_show(9)

✨ NAME ✨

okay bestie, this is the sht21_humidity_show(9) page from the Kernel API Manual, and it's literally about showing the humidity measurement value in sysfs. 💖

🌸 SYNOPSIS 🌸

ssize_t sht21_humidity_show (struct device *dev , struct
       device_attribute *attr , char *buf );

🎀 ARGUMENTS 🎀

• dev — device
• attr — device attribute
• buf — sysfs buffer (PAGE_SIZE) where measurement values are written to

🦋 DESCRIPTION 🦋

Bestie, listen: this gets called on read access to the humidity1_input sysfs attribute. That's the whole vibe check. 👑

It returns the number of bytes written into the buffer, and on error it returns a negative errno. No cap. 💅
