NAME         top

       gnutls_x509_trust_list_verify_crt - API function

SYNOPSIS         top

       #include <gnutls/x509.h>

       int gnutls_x509_trust_list_verify_crt(gnutls_x509_trust_list_t
       list, gnutls_x509_crt_t * cert_list, unsigned int cert_list_size,
       unsigned int flags, unsigned int * voutput,
       gnutls_verify_output_function func);

ARGUMENTS         top

       gnutls_x509_trust_list_t list
                   The list

       gnutls_x509_crt_t * cert_list
                   is the certificate list to be verified

       unsigned int cert_list_size
                   is the certificate list size

       unsigned int flags
                   Flags that may be used to change the verification
                   algorithm. Use OR of the
                   gnutls_certificate_verify_flags enumerations.

       unsigned int * voutput
                   will hold the certificate verification output.

       gnutls_verify_output_function func
                   If non-null will be called on each chain element
                   verification with the output.

DESCRIPTION         top

       This function will try to verify the given certificate and return
       its status. The  voutput parameter will hold an OR'ed sequence of
       gnutls_certificate_status_t flags.

       The details of the verification are the same as in
       gnutls_x509_trust_list_verify_crt2().

RETURNS         top

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative
       error value.

SINCE         top
