IVI Inherent Function

To form the ClassPrefix VI name, use the prefix of the class driver that you are working with. For example, if you are working with the IviDmm class driver, use the prefix IviDmm to create the correct VI name, IviDmm Close.

This VI performs the following operations:

  • Closes the instrument I/O session.
  • Destroys the instrument driver session and all of its properties.
  • Deallocates any memory resources the driver uses.
Note  After calling ClassPrefix Close, you cannot use the instrument driver again until you call ClassPrefix Initialize.
instrument handle The instrument handle that you obtain from the ClassPrefix Initialize or ClassPrefix Initialize With Options VI. The handle identifies a particular instrument session.
error in (no error) Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.

error out The error out cluster passes error or warning information out of a VI to be used by other VIs.

The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed.
