POWER(4) | Device Drivers Manual (landisk) | POWER(4)

# NAME

`power` — power switch

# SYNOPSIS

`power0 at obio?`

# DESCRIPTION

Landisk models provide an interrupt when the power switch is flipped to the Off position. The `power` driver catches that interrupt. If the hw.allowpowerdown sysctl(8) is set to 1, `power` will signal init(8) to do a clean shutdown.

# SEE ALSO

# HISTORY

Support for the `power` driver first appeared in OpenBSD 4.1.
