DEVICE_DETACH(9)                  BSD 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.

SEE ALSO
     pccard(4), device(9), DEVICE_ATTACH(9), DEVICE_IDENTIFY(9), DEVICE_PROBE(9),
     DEVICE_SHUTDOWN(9)
