kernel_can_power_off(9)

🎀 NAME 🎀

kernel_can_power_off — bestie, this one literally just checks whether the system can be powered off 💅

(also hi, this page lives in the Kernel API Manual, section 9, and it's giving very "quick vibe check before we shut the whole thing down" energy ✨)

✨ SYNOPSIS ✨

bool kernel_can_power_off (void );

🦋 ARGUMENTS 🦋

• void — no arguments, babe. none. zero. it takes nothing 🙈

💖 DESCRIPTION 💖

Returns true if a power-off handler is registered and the system can be powered off. Otherwise it returns false. That's the whole tea ☕ — it's a yes/no check, not an action. No cap.
