acpi_evaluate_lck(9)

NAME 💖

okay so bestie, welcome to the acpi_evaluate_lck(9) page from the Kernel API Manual ✨ this is the little ACPI helper whose whole thing is: evaluate _LCK method to lock/unlock device. no cap, that’s the name-section vibe.

SYNOPSIS ✨

acpi_status acpi_evaluate_lck (acpi_handle handle , int lock );

ARGUMENTS 🎀

• handle — ACPI device handle. literally the device handle we’re working with.
• lock — lock device if non-zero, otherwise unlock device. so non-zero = lock, zero = unlock. periodt.

DESCRIPTION 🦋

Evaluate device's _LCK method if present to lock/unlock device. yep — if the device has that _LCK method, this evaluates it to lock or unlock the device. the “if present” part is important, bestie; it’s not out here inventing methods that aren’t there.
