DEVICE_ATTACH(9) |
NAME
DEVICE_ATTACH —
attach a device
DESCRIPTION
Attach a device to the system after the
DEVICE_PROBE() method has been called and has indicated that the device exists. The
DEVICE_ATTACH() method should initialize the hardware and allocate other system resources (such as
devfs(5) entries).
Devices which implement busses should use this method to probe for the existence of devices attached to the bus and add them as children. If this is combined with the use of bus_generic_attach(9) the child devices will be automatically probed and attached.
RETURN VALUES
Zero is returned on success, otherwise an appropriate error is returned.
