An example of this is specifying  a particular instrument model from among a family of instruments  that the driver supports.  This is useful when using simulation.

    Specifies whether to perform interchangeability checking and retrieve  interchangeability warnings when you call  niSwitch_Connect, niSwitch_SetPath and niSwitch_InitiateScan functions.

    Interchangeability warnings indicate that using your application with a  different instrument might cause different behavior.   You call niSwitch_GetNextInterchangeWarning to extract interchange warnings.   Call the niSwitch_ClearInterchangeWarnings function to clear the list  of interchangeability warnings without reading them.
    Interchangeability checking examines the attributes in a  capability group only if you specify a value for at least one  attribute within that group.  Interchangeability warnings can  occur when an attribute affects the behavior of the instrument and you  have not set that attribute, or the attribute has been invalidated since you set it.
