gnutls_x509_crt_get_issuer_dn - API function
int gnutls_x509_crt_get_issuer_dn(gnutls_x509_crt_t cert, char * buf,
size_t * buf_size);
should contain a gnutls_x509_crt_t type
char * buf a pointer to a structure to hold the name (may be null)
size_t * buf_size
initially holds the size of buf
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().
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.
