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
