@deftypefun {void} {gnutls_session_set_verify_cert2} (gnutls_session_t @var{session}, gnutls_typed_vdata_st * @var{data}, unsigned @var{elements}, unsigned @var{flags}) @var{session}: is a gnutls session @var{data}: an array of typed data @var{elements}: the number of data elements @var{flags}: flags for certificate verification -- @code{gnutls_certificate_verify_flags} This function instructs GnuTLS to verify the peer's certificate using the provided typed data information. If the verification fails the handshake will also fail with @code{GNUTLS_E_CERTIFICATE_VERIFICATION_ERROR} . In that case the verification result can be obtained using @code{gnutls_session_get_verify_cert_status()} . The acceptable typed data are the same as in @code{gnutls_certificate_verify_peers()} , and once set must remain valid for the lifetime of the session. More precisely they should be available during any subsequent handshakes. If @code{flags} is provided which contain a profile, this function should be called after any session priority setting functions. @strong{Since:} 3.4.6 @end deftypefun
