DESCRIPTION         top

       This function adds the trusted CAs in order to verify client or
       server certificates. In case of a client this is not required to
       be called if the certificates are not verified using
       gnutls_certificate_verify_peers2().  This function may be called
       multiple times.

       In case of a server the names of the CAs set here will be sent to
       the client if a certificate request is sent. This can be disabled
       using gnutls_certificate_send_x509_rdn_sequence().

       This function can also accept URLs. In that case it will import
       all certificates that are marked as trusted. Note that the
       supported URLs are the ones indicated by
