|

*
|

* NOTE:
|
||||
* - in non-thread mode only asynchronous service functions can be used!
|

* - the IedConnection_tick function has to be called periodically
|

* - the asynchronous API returns service results by callback functions
|

*
|

* This example is intended to be used with server_example_basic_io.
