  // That the following code works there must be in the FIBEX 4.1
  // database a node providing under an unreliable endpoint
  // (UDP socket) the following objects:
  //  - A service instance named "Service_Test"
  //  - An event group named "All" belonging to "Service_Test"
  //  - An event named "Event_Test" belonging to "All"
  //  - A field named "Field_Test" belonging to "All" and having a notifier, a getter and a setter
  //  - A node consuming the event group "All"

  DWORD psi; // provided service instance handle
  DWORD peg; // provided event group handle
