OnFinalClose Method

Called during the execution of the Close method of a driver.

virtual HRESULT OnFinalClose();

File

Co<MainClass>.cpp

Co<RepCapClass>.cpp

Return Value

Returns S_OK if successful, otherwise a failure HRESULT.

Remarks

The OnFinalClose method can be used to perform driver-specific actions immediately after each client call to IIviDriver::Close. This function is called after the call to the IIviDriver::Close implementation. Repeated capability classes also have an OnFinalClose method that is called before the OnFinalClose of the main driver class.

Note
By the time this function executes, the instrument I/O infrastructure has already been torn down. Thus, none of the instrument I/O functions can be used within this function.
