Returns the status code of this operation.  The status code  either indicates success or describes an error or warning condition.  You examine the status code from each call to an instrument driver function to determine if an error occurred.
To obtain a text description of the status code, call the pi40iv_error_message function.  To obtain additional information about the error condition, call the pi40iv_GetErrorInfo function.  To clear the error information from the driver, call the pi40iv_ClearErrorInfo function.
The general meaning of the status code is as follows:
Value                  Meaning
