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.
