BUS_PRINT_CHILD(9) BSD Kernel Developer's Manual BUS_PRINT_CHILD(9)NAME
BUS_PRINT_CHILD -- print information about a device
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>
int
BUS_PRINT_CHILD(device_t dev, device_t child);
DESCRIPTION
The BUS_PRINT_CHILD() method is called from system code which prints out a description of a device. It should describe the attachment that
the child has with the parent. For instance the TurboLaser bus prints which node the device is attached to. Please see
bus_generic_print_child(9) for more information regarding the proper formatting of the messages printed by BUS_PRINT_CHILD().

DEVICE_ATTACH(9) BSD Kernel Developer's Manual 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.
