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

Starts the enumeration of buzzers currently accessible. Use the method YBuzzer.nextBuzzer() to iterate on next buzzers.
- Returns
- a pointer to a YBuzzer object, corresponding to the first buzzer currently online, or a NULL pointer if there are none.
