PIBIO_ENGINE_PIPELINE_CLEANUP_FN callback function

-description

Called by the Windows Biometric Framework to give the Engine Adapter the chance to perform any cleanup that requires help from the Storage Adapter.

-parameters

-param Pipeline [in, out]

Pointer to the WINBIO_PIPELINE structure associated with the biometric unit performing the operation.

-returns

If the function succeeds, it returns S_OK. If the function fails, it must return one of the following HRESULT values to indicate the error.

Return code	Description
E_POINTER	The Pipeline parameter cannot be NULL.

-remarks

This method is called once, when a biometric unit is being torn down.

The Engine Adapter should return S_OK if it doesn’t need to perform any cleanup at this point.

This method executes in the context of an arbitrary RPC server thread.
