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)
