NAME         top

       gnutls_ocsp_status_request_is_checked - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       unsigned gnutls_ocsp_status_request_is_checked(gnutls_session_t
       session, unsigned int flags);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls session

       unsigned int flags
                   should be zero or GNUTLS_OCSP_SR_IS_AVAIL

DESCRIPTION         top

       When flags are zero this function returns non-zero if a valid
       OCSP status response was included in the TLS handshake. That is,
       an OCSP status response which is not too old, superseded or marks
       the certificate as revoked.  It returns zero otherwise.

       When the flag GNUTLS_OCSP_SR_IS_AVAIL is specified, the function
       returns non-zero if an OCSP status response was included in the
       handshake even if it was invalid. Otherwise, if no OCSP status
       response was included, it returns zero. The
       GNUTLS_OCSP_SR_IS_AVAIL flag was introduced in GnuTLS 3.4.0.

       This is a helper function when needing to decide whether to
       perform an explicit OCSP validity check on the peer's
       certificate. Should be called after any of
       gnutls_certificate_verify_peers*() are called.

       This function is always usable on client side, but on server side
       only under TLS 1.3, which is the first version of TLS that allows
       cliend-side OCSP responses.

RETURNS         top

       Non-zero if the response was valid, or a zero if it wasn't sent,
       or sent and was invalid.
