Use OR of the gnutls_certificate_verify_flags enumerations. @var{voutput}: will hold the certificate verification output. @var{func}: If non-null will be called on each chain element verification with the output. This function will try to verify the given certificate and return its status. The @code{voutput} parameter will hold an OR'ed sequence of @code{gnutls_certificate_status_t} flags. The details of the verification are the same as in @code{gnutls_x509_trust_list_verify_crt2()} . @strong{Returns:} On success, @code{GNUTLS_E_SUCCESS} (0) is returned, otherwise a negative error value. @strong{Since:} 3.0 @end deftypefun
