DESCRIPTION         top

       This function will set the subject alternative name certificate
       extension. It can set the following types: GNUTLS_SAN_DNSNAME as a
       text string, GNUTLS_SAN_RFC822NAME as a text string,
       GNUTLS_SAN_URI as a text string, GNUTLS_SAN_IPADDRESS as a binary
       IP address (4 or 16 bytes), GNUTLS_SAN_OTHERNAME_XMPP as a UTF8
       string (since 3.5.0).

       Since version 3.5.7 the GNUTLS_SAN_RFC822NAME, GNUTLS_SAN_DNSNAME,
       and GNUTLS_SAN_OTHERNAME_XMPP are converted to ACE format when
       necessary.

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
       error value.

SINCE         top
