If ``pSignature`` is NULL only the length of the signature is returned in 52 ``*pusSignatureLen``. 53 54 A user must log into the token (to assume the NSS User role) before calling ``FC_VerifyRecover``. 55 56 .. _return_value: 57 58 `Return value <#return_value>`__ 59 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 60 61 .. container:: 62 63 `Examples <#examples>`__ 64 ~~~~~~~~~~~~~~~~~~~~~~~~ 65 66 .. container:: 67 68 .. _see_also: 69 70 `See also <#see_also>`__ 71 ~~~~~~~~~~~~~~~~~~~~~~~~ 72 73 .. container:: 74 75 - `NSC_VerifyRecover </en-US/NSC_VerifyRecover>`__
