@deftypefun {int} {gnutls_x509_crt_set_dn} (gnutls_x509_crt_t @var{crt}, const char * @var{dn}, const char ** @var{err})

@var{crt}: a certificate of type @code{gnutls_x509_crt_t} 

@var{dn}: a comma separated DN string (RFC4514)

@var{err}: indicates the error position (if any)

This function will set the DN on the provided certificate.

The input string should be plain ASCII or UTF-8 encoded. On

DN parsing error @code{GNUTLS_E_PARSING_ERROR}  is returned.

Note that DNs are not expected to hold DNS information, and thus

no automatic IDNA conversions are attempted when using this function.

If that is required (e.g., store a domain in CN), process the corresponding

input with @code{gnutls_idna_map()} .

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a

negative error value.
