read_powermode(9)

🌸 NAME 🌸

okay bestie, say hi to read_powermode(9) — the Kernel API Manual page that's literally here to query the power mode of the slave. 🫶 No cap, that's the whole name vibe.

⚡ SYNOPSIS ⚡

int read_powermode (struct w1_slave *sl );

🎀 ARGUMENTS 🎀

• sl — the slave you want to retrieve the power mode from, bestie. 🦋

✨ DESCRIPTION ✨

It asks the device to get its power mode — external or parasite — and stores the power status in the struct w1_therm_family_data. That's it, that's the function, and it's giving very focused main character energy. 💅

🔥 RETURN 🔥

• 0 — parasite powered device 🌸
• 1 — externally powered device ⚡
• <0 — kernel error code 😭
