thermal_bind_cdev_to_trip(9)

okay so bestie, welcome to the Kernel API Manual page for thermal_bind_cdev_to_trip(9) 💅✨ This is the one where a cooling device gets bound to a trip point, and honestly it’s giving “small function, big thermal-zone energy.”

🎀 NAME 🎀

thermal_bind_cdev_to_trip - bind a cooling device to a thermal zone 💖

✨ SYNOPSIS ✨

int thermal_bind_cdev_to_trip (struct thermal_zone_device *tz , struct
       thermal_trip_desc *td , struct thermal_cooling_device *cdev , struct
       cooling_spec *cool_spec );

🌸 ARGUMENTS 🌸

okay, the cast of characters:

• tz — pointer to struct thermal_zone_device 👑
• td — descriptor of the trip point to bind cdev to 🎯
• cdev — pointer to struct thermal_cooling_device 🧊
• cool_spec — cooling specification for the trip point and cdev 🍓

🦋 DESCRIPTION 🦋

This interface function binds a thermal cooling device to a certain trip point of a thermal zone device. no cap, that’s the whole vibe.

This function is usually called in the thermal zone device .bind callback. iykyk 💅

🔥 RETURN 🔥

0 on success, the proper error value otherwise. that’s it bestie — success gets the 0, everything else gets the proper error value 😭
