12       int gnutls_x509_crt_get_issuer_dn(gnutls_x509_crt_t cert, char  *  buf,
13       size_t * sizeof_buf);
14

ARGUMENTS

16       gnutls_x509_crt_t cert
17                   should contain a gnutls_x509_crt_t structure
18
19       char * buf  a pointer to a structure to hold the name (may be null)
20
21       size_t * sizeof_buf
22                   initially holds the size of buf

DESCRIPTION

25       This  function will copy the name of the Certificate issuer in the pro‐
26       vided buffer. The name will be in the form  "C=xxxx,O=yyyy,CN=zzzz"  as
27       described in RFC2253. The output string will be ASCII or UTF-8 encoded,
28       depending on the certificate data.

30       If buf is null then only the size will be filled.
31

RETURNS

33       GNUTLS_E_SHORT_MEMORY_BUFFER if the provided buffer is not long enough,
34       and  in  that  case  the  *sizeof_buf will be updated with the required
35       size.  On success 0 is returned.
