This function returns the value of a certificate field, when that field occurs multiple times in a certificate. Certificates with repeated fields (such as multiple signatures) have multiple field values corresponding to a single OID. A call to the function CSSM_CL_CertGetFirstFieldValue initiates the process and returns a results handle identifying the certificate from which values are being obtained and the OID corresponding to those values. The CSSM_CL_CertGetNextFieldValue function can be called repeatedly to obtain these values one at a time.
