Retrieves a dual power 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 control is online at the time it is invoked. The returned object is nevertheless valid. Use the method YDualPower.isOnline() to test if the power control is indeed online at a given time. In case of ambiguity when looking for a dual power 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 control |
- Returns
- a YDualPower object allowing you to drive the power control.

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