 PFNCryptStreamOutputCallbackEx

 pvCallbackCtxt
    The arguments specified by NCRYPT_PROTECT_STREAM_INFO_EX.

 pbData
    A pointer to a block of processed data that is available to the application.  If
    data is not available yet, but the descriptor is, this will be NULL.

 cbData
    The size, in bytes, of the block of processed data at pbData.

 hDescriptor
    Handle of Protection Descriptor.

 fFinal
    Specifies that the last block of data is being processed and that this
    is the last time the callback will be executed.

 Return Value
    Returns a status code that indicates the success or failure of the function.
    Possible return codes include, but are not limited to, the following.

    ERROR_SUCCESS
    NTE_INVALID_PARAMETER
    NTE_BAD_FLAGS
    NTE_BAD_DATA
    NTE_NO_MEMORY
    NTE_NOT_FOUND
    NTE_NOT_SUPPORTED
    NTE_INVALID_HANDLE
    NTE_BAD_KEY

 NCRYPT_PROTECT_STREAM_INFO_EX

    The NCRYPT_PROTECT_STREAM_INFO_EX structure is used to enable stream processing
    of data rather than single block processing.
    This structure is passed to the NCryptStreamOpenToUnprotectEx function.  There
    is not equivalent NCryptStreamOpenToProtectEx function, thus you need to use
    the PFNCryptStreamOutputCallback, NCRYPT_PROTECT_STREAM_INFO and
    NCryptStreamOpenToProtect functions.

    pfnStreamOutput
        [in] The address of a callback function used to read from and write
        data to a disk when processing large messages.

    pvCallbackCtxt
        [in] A pointer to the argument to pass to the callback function.

    pStreamInfo
        [in] A pointer to NCRYPT_PROTECT_STREAM_INFO_EX.

    dwFlags
        The following flags are supported.
        NCRYPT_SILENT_FLAG

    hWnd
        [in, optional] A window handle (HWND) to be used as the parent of any user
        interface that is displayed.

    phStream
        [out] Receives a pointer to a stream handle.
