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.
