Описание (Description)
This function will copy the name of the Certificate issuer in the
provided buffer. The name will be in the form
"C=xxxx,O=yyyy,CN=zzzz" as described in RFC4514. The output
string will be ASCII or UTF-8 encoded, depending on the
certificate data.
If buf is null then only the size will be filled.
This function does not output a fully RFC4514 compliant string,
if that is required see gnutls_x509_crt_get_issuer_dn3().
Возвращаемое значение (Return value)
GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long
enough, and in that case the buf_size will be updated with the
required size. GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the DN
does not exist, or another error value on error. On success 0 is
returned.
