sht15_temp_show(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– sht15_temp_show(9) β€” Kernel API Manual vibes πŸ’–

okay so bestie, welcome to the sht15_temp_show(9) page, straight out of the Kernel API Manual ✨ this one's short and sweet and honestly kind of iconic for how much it does with so little πŸŽ€


🌸 NAME 🌸

sht15_temp_show β€” shows off the temperature measurement value in sysfs, no cap πŸ”₯


✨ SYNOPSIS ✨

ssize_t sht15_temp_show (struct device *dev , struct device_attribute
*attr , char *buf );

like, that's the whole signature, that's the assignment πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • dev β€” the device. that's it, that's the whole description, she's a device and we respect her 🫢
  • attr β€” the device attribute. also extremely brief. main character energy with zero elaboration ✨
  • buf β€” the sysfs buffer, and this is the one where the measurement values actually get written to πŸ“ literally the whole point of the function lives here.

πŸ’œ DESCRIPTION πŸ’œ

so the kernel will call this lil function whenever someone does a read access on the temp1_input sysfs attribute πŸ‘€ that's the vibe check that triggers the whole thing.

It returns the number of bytes written into the buffer, and if something goes sideways it returns a negative errno instead 😭 so like β€” success gives you a byte count, failure gives you a sad little negative number. that's the contract, periodt.
