niSwitch Get Next Coercion Record
Returns the coercion information associated with the IVI session. This VI retrieves and clears the oldest instance in which the instrument driver coerced a value you specified to another value.
If you set the Record Coercions property to TRUE, NI-SWITCH keeps a list of all coercions it makes on ViInt32 or ViReal64 values you pass to instrument driver VIs. You use this VI to retrieve information from that list.
The VI returns an empty string if no coercion records remain for the session.

instrument handle identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize. | ||||||

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs 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 identifies a particular NI-SWITCH session established with niSwitch Initialize With Topology, niSwitch Initialize With Options, or niSwitch Initialize and used for all subsequent NI-SWITCH calls. | ||||||
 |
coercion record is the next coercion record for the IVI session. If there are no coercion records remaining for the session, the VI returns an empty string. | ||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function 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.
