|
.Pp
|
||
|
|
The method
|
||
|
|
.Xr BUS_CREATE_INTR 9
|
||
|
|
creates an interrupt handler for the child device. The handler
|
||
|
|
.Fa intr
|

|
|
will be called with the value
|
||
|
|
.Fa arg
|
||
|
|
as its only argument.
|
||
|
|
The handle returned can be used in a call to
|
||
|
|
.Xr BUS_CONNECT_INTR 9
|
||
|
|
to activate the handler.
|
||
|
|
.Sh RETURN VALUES
|
||
|
|
An opaque handle which can be used to activate the interrupt is
|
||
|
|
returned if the call is successful, otherwise NULL is returned.
