Retrieves a dual power ouput control for a given identifier. The identifier can be specified using several formats:
-
FunctionLogicalName
-
ModuleSerialNumber.FunctionIdentifier
-
ModuleSerialNumber.FunctionLogicalName
-
ModuleLogicalName.FunctionIdentifier
-
ModuleLogicalName.FunctionLogicalName
This function does not require that the power ouput control is online at the time it is invoked. The returned object is nevertheless valid. Use the method YPowerOutput.isOnline() to test if the power ouput control is indeed online at a given time. In case of ambiguity when looking for a dual power ouput control by logical name, no error is notified: the first instance found is returned. The search is performed first by hardware name, then by logical name.
If a call to this object's is_online() method returns FALSE although you are certain that the matching device is plugged, make sure that you did call registerHub() at application initialization time.
- Parameters
-
func | : a string that uniquely characterizes the power ouput control |
- Returns
- a YPowerOutput object allowing you to drive the power ouput control.

Starts the enumeration of dual power ouput controls currently accessible. Use the method YPowerOutput.nextPowerOutput() to iterate on next dual power ouput controls.
- Returns
- a pointer to a YPowerOutput object, corresponding to the first dual power ouput control currently online, or a NULL pointer if there are none.
