NAME

DEVICE_DETACH — detach a device

SYNOPSIS

#include < sys/param.h>
#include < sys/bus.h>

int
DEVICE_DETACH( device_t dev);

DESCRIPTION

Detach a device. This can be called if the user is replacing the driver software or if a device is about to be physically removed from the system (e.g. for pccard(4) devices).

The method should deallocate any system resources allocated during the DEVICE_ATTACH(9) method and reset the hardware to a sane state (i.e., disable interrupts etc.)

RETURN VALUES

Zero is returned on success, otherwise an appropriate error is returned.
