Get the revocation state of the certificate chain of the signature's certificate. verifyCertificateChain() must have been called successfully. getErrorMessage() will return an error message if the verification result returned is not #crs_ok. If #vf_check_revocation was not set in integer parameter "VerificationFlags" for the most recent call to verifyCertificateChain(), this function will return #crs_not_checked. This function fails for document time stamps, see getMethod() and getTimeStampCertificateRevocationState().
