cert, unsigned int seq, void * ret, size_t * ret_size);
should contain a gnutls_x509_crt_t type
unsigned int seq
specifies the sequence number of the alt name (0 for the
first one, 1 for the second etc.)
void * ret is the place where the otherName OID will be copied to
size_t * ret_size
holds the size of ret.
This function will extract the type OID of an otherName Subject
Alternative Name, contained in the given certificate, and return the
type as an enumerated element.
If oid is null then only the size will be filled. The oid returned
will be null terminated, although oid_size will not account for the
This function is only useful if gnutls_x509_crt_get_issuer_alt_name()
the alternative issuer name type on success, one of the enumerated
gnutls_x509_subject_alt_name_t. For supported OIDs, it will return one
of the virtual (GNUTLS_SAN_OTHERNAME_*) types, e.g.
GNUTLS_SAN_OTHERNAME_XMPP, and GNUTLS_SAN_OTHERNAME for unknown OIDs.
It will return GNUTLS_E_SHORT_MEMORY_BUFFER if
ret_size is not large enough to hold the value. In that case
ret_size will be updated with the required size. If the certificate
does not have an Alternative name with the specified sequence number
and with the otherName type then GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE
