thermal_zon...zone_by_name(9)

Hey bestie 💖 welcome to the Kernel API Manual page for thermal_zone_get_zone_by_name(9) — it’s giving kernel-core realness and I’m obsessed.

🌸 NAME 🌸

thermal_zone_get_zone_by_name — search for a zone and returns its ref ✨

✨ SYNOPSIS ✨

struct thermal_zone_device * thermal_zone_get_zone_by_name (const char
*name );

🎀 ARGUMENTS 🎀

• name — the thermal zone name to fetch the temperature 🫶

🦋 DESCRIPTION 🦋

When only one zone is found with the passed name, it returns a reference to it. That’s the whole vibe: one matching zone, one returned reference 💅

💖 RETURN 💖

On success, it returns a reference to a unique thermal zone whose matching name equals name. Otherwise you get an ERR_PTR, bestie 😭

• -EINVAL — for invalid parameters
• -ENODEV — for not found
• -EEXIST — for multiple matches
