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.
