NAME

       gnutls_x509_crt_get_issuer_dn - API function

SYNOPSIS

       #include <gnutls/x509.h>

       int gnutls_x509_crt_get_issuer_dn(gnutls_x509_crt_t cert, char * buf, size_t * buf_size);

ARGUMENTS

       gnutls_x509_crt_t cert
                   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

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().

RETURNS

       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.
