``FC_SignFinal`` finishes a multi-part signing operation by returning the complete signature and
clearing the operation context. If ``pSignature`` is NULL the length of the signature is returned
and ``FC_SignFinal`` may be called again with ``pSignature`` set to retrieve the signature.
A user must log into the token (to assume the NSS User role) before calling ``FC_SignFinal``.
