BUS_ADD_CHILD(9)

NAME

     BUS_ADD_CHILD -- add a device node to the tree with a given priority

SYNOPSIS

     #include <sys/param.h>
     #include <sys/bus.h>

     int
     BUS_ADD_CHILD(device_t dev, int order, const char *name, int unit);

DESCRIPTION

     The BUS_ADD_CHILD() method is used by the driver identify routine to add
     devices to the tree.  Please see device_add_child(9) for more details.
     The interface is the same as device_add_child(9) however, the bus'
     BUS_ADD_CHILD() is called.

     Busses implementing BUS_ADD_CHILD() should insert the device into the
     tree using device_add_child(9) before adding things such as their own
     ivars and resource lists to the device.

SEE ALSO

     device(9), device_add_child(9), driver(9)

RETURN VALUES

     The BUS_ADD_CHILD() method returns device_t added to the tree, or NULL.
