            LPVOID lpClientData,
            LPHIG_PDF_STREAM lphStream 
    );
    

    Arguments:

    Name Type Description
    lpfnReadProc LPFNIG_PDF_STREAM_PROC User-supplied callback that supplies the stream's data.
    lpClientData LPVOID Pointer to user-supplied data to pass to lpfnReadProc each time it is called.
