Returns the interchangeability warnings associated with the IVI session. This VI retrieves and clears the oldest instance in which the class driver recorded an interchangeability warning. Interchangeability warnings indicate that using your application with a different instrument might cause different behavior.

NI-SWITCH performs interchangeability checking when the Interchange Check property is set to TRUE.

The VI returns an empty string for interchange warning if no interchangeability warnings remain for the session.

In general, NI-SWITCH generates interchangeability warnings when a property that affects the behavior of the switch is in a state that you did not specify.
