33.Os
34.Sh NAME
35.Nm bus_generic_print_child
36.Nd generic implementation of
37.Dv DEVICE_PRINT_CHILD
38for buses
39.Sh SYNOPSIS
40.In sys/param.h
41.In sys/bus.h
42.Ft int
43.Fn bus_generic_print_child "device_t dev" "device_t child"
44.Sh DESCRIPTION
45This implementation prints out the default device announcement message.
46Given device 'foo0' on bus 'bar0' where foo0 has the name "FooCard 1234" the
47following would be printed:
48.Pp
49foo0: <FooCard 1234> on bar0
50.Pp
51bus_generic_print_child itself calls two functions
52.Fn bus_print_child_header
53and
54.Fn bus_print_child_footer .
55The former prints "foo0: <FooCard 1234>" and the latter "on bar0".
56These routines should be used if possible in your own code if
57.Fn bus_generic_print_child
58does not completely suit your needs.
59.Sh RETURN VALUES
60The number of characters output.
