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 * oid is the place where the otherName OID will be copied to
size_t * oid_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.
This function is only useful if
gnutls_x509_crt_get_subject_alt_name() returned GNUTLS_SAN_OTHERNAME.
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
the alternative subject 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
ian_size is not large enough to hold the value. In that case
ian_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 is returned.
