@deftypefun {int} {gnutls_x509_crq_set_dn} (gnutls_x509_crq_t @var{crq}, const char * @var{dn}, const char ** @var{err})
@var{crq}: a certificate of type @code{gnutls_x509_crq_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.

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