@deftypefun {int} {gnutls_x509_crt_list_verify} (const gnutls_x509_crt_t * @var{cert_list}, unsigned @var{cert_list_length}, const gnutls_x509_crt_t * @var{CA_list}, unsigned @var{CA_list_length}, const gnutls_x509_crl_t * @var{CRL_list}, unsigned @var{CRL_list_length}, unsigned int @var{flags}, unsigned int * @var{verify}) @var{cert_list}: is the certificate list to be verified @var{cert_list_length}: holds the number of certificate in cert_list @var{CA_list}: is the CA list which will be used in verification @var{CA_list_length}: holds the number of CA certificate in CA_list @var{CRL_list}: holds a list of CRLs. @var{CRL_list_length}: the length of CRL list. @var{flags}: Flags that may be used to change the verification algorithm. Use OR of the gnutls_certificate_verify_flags enumerations. @var{verify}: will hold the certificate verification output. This function will try to verify the given certificate list and return its status. The details of the verification are the same as in @code{gnutls_x509_trust_list_verify_crt2()} . You must check the peer's name in order to check if the verified certificate belongs to the actual peer. The certificate verification output will be put in @code{verify} and will be one or more of the gnutls_certificate_status_t enumerated elements bitwise or'd. For a more detailed verification status use @code{gnutls_x509_crt_verify()} per list element. @strong{Returns:} On success, @code{GNUTLS_E_SUCCESS} (0) is returned, otherwise a negative error value. @end deftypefun
