Catch application 'kill' with event

    All,

    I want to do some emergency actions when my application is 'killed' e.g. '> sudo pkill codesys'.
    Does CoDeSys provide a way to 'catch' a 'kill' event?

    I found the callback library. And I tried:

    cbNew.eEvent := CB.EVENT.STOP;
    cbNew.eClass := CB.EVENT_CLASS.ONLINE_EVENTS;
    cbNew.eSource := CB.EVENT_SOURCE.ALL_SOURCES;
    cbNew.pPOUFunc := ADR(CallbackON_EVENT_STOP);
    CB.RegisterCallback(cbNew := cbNew, peError := ADR(eError));
    

    This catches the transition to the STOP state.
    What parameters do I use to catch a CoDeSys 'kill'?
    I searched in the CB.EVENT, CB.EVENT_CLASS and CB.EVENT_SOURCE enumerations, but cannot find anything.

    Regards,
    Edwin.

    I found these values:

    dwSpec dwParam dwSource action
    03E90001 00000022 00000004 stop
    03E90001 00000022 00000003 div by zero
    03E90001 00000022 00000001 kill
    

    Regards,
