the alternative subject name type on success, one of the enumerated gnutls_x509_subject_alt_name_t. It will return GNUTLS_E_SHORT_MEMORY_BUFFER if san_size is not large enough to hold the value.

If the certificate does not have an Alternative name with the specified sequence number then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE is returned.
