niDMM Get Next Interchange Warning
Returns the interchangeability warnings associated with the IVI session. It 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-DMM performs interchangeability checking when the Interchange Check property is set to TRUE (1). This VI returns an empty string in the interchange warning parameter if no interchangeability warnings remain for the session. In general, NI-DMM generates interchangeability warnings when a property that affects the behavior of the instrument is in a state that you did not specify.

instrument handle identifies a particular instrument session. You obtain the instrument handle parameter from niDMM Initialize or niDMM Initialize With Options. The default is None. |

error in (no error) describes error conditions that occur before this VI runs. If an error occurred before this VI runs, the VI passes the error in value to error out. This VI runs normally only if no error occurs before this VI runs. If an error occurs while this VI runs, it continues and sets its own error status in error out. Use niDMM Error Message to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

instrument handle out returns a handle that you use to identify the instrument in all subsequent instrument driver VI calls. |

 |
interchange warning returns the next interchange warning for the IVI session. If there are no interchange warnings, the VI returns an empty string. The buffer must contain at least as many elements as the value you specify with the Buffer Size property. |

 |
error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
