DEVICE_DETACH(9) FreeBSD Kernel Developer's Manual DEVICE_DETACH(9)
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.
