DEVICE_DETACH(9)      DragonFly 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 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. dis-
     able interrupts etc.)

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