->Detaching Power Controllers</H2

->By default the global operation <TT
-CLASS="FUNCTION"
->power_set_mode</TT
->
-affects all power controllers. There may be circumstances when this is
-not desirable. For example if a particular device is not currently
-being used then it can be left switched off: the rest of the system
-could be moving between <SPAN
-CLASS="TYPE"
->active</SPAN
->, <SPAN
-CLASS="TYPE"
->idle</SPAN
-> and
-<SPAN
-CLASS="TYPE"
->sleep</SPAN
-> modes, but there is no point in invoking the power
-controller for the unused device. To support this the power management
-package supports the concept of attached and detached controllers. By
-default all controllers are attached, and hence will be affected by
-global mode changes. A specific controller can be detached using the
-function <TT
-CLASS="FUNCTION"
->power_set_controller_attached</TT
->. This
-function takes two arguments, one to specify a particular controller
-and another to specify the desired new state.
-<TT
-CLASS="FUNCTION"
->power_get_controller_attached</TT
-> can be used to
-determine whether or not a specific controller is currently attached.</P
-><P
->The attached or detached state of a controller only affects what
-happens during a global mode change, in other words following a call
-to <TT
-CLASS="FUNCTION"
->power_set_mode</TT
->. It is still possible to
-manipulate a detached controller using
-<TT
-CLASS="FUNCTION"
->power_set_controller_mode</TT
-> or
-<TT
-CLASS="FUNCTION"
->power_set_controller_mode_now</TT
->.</P
