device_attach(9)

NAME

DEVICE_ATTACH - attach a device

SYNOPSIS

#include <sys/param.h>
#include <sys/bus.h>
int
DEVICE_ATTACH(device_t dev);

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.
