10
11       int  gnutls_x509_crt_get_issuer_dn(gnutls_x509_crt_t  cert, char * buf,
12       size_t * buf_size);
13

ARGUMENTS

15       gnutls_x509_crt_t cert
16                   should contain a gnutls_x509_crt_t type
17
18       char * buf  a pointer to a structure to hold the name (may be null)

DESCRIPTION

24       This function will copy the name of the Certificate issuer in the  pro‐
25       vided  buffer.  The name will be in the form "C=xxxx,O=yyyy,CN=zzzz" as
26       described in RFC4514. The output string will be ASCII or UTF-8 encoded,
27       depending on the certificate data.
28
29       If  buf is null then only the size will be filled.
30
31       This function does not output a fully RFC4514 compliant string, if that
32       is required see gnutls_x509_crt_get_issuer_dn3().
33

RETURNS

35       GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough,
36       and  in that case the  buf_size will be updated with the required size.
37       GNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE if the  DN  does  not  exist,  or
38       another error value on error. On success 0 is returned.
