NAME

       SSL_session_reused - query whether a reused session was negotiated during handshake

SYNOPSIS

        #include <openssl/ssl.h>

        int SSL_session_reused(SSL *ssl);

DESCRIPTION

       Query, whether a reused session was negotiated during the handshake.

NOTES

       During the negotiation, a client can propose to reuse a session. The server then looks up
       the session in its cache. If both client and server agree on the session, it will be
       reused and a flag is being set that can be queried by the application.

RETURN VALUES

       The following return values can occur:

       0   A new session was negotiated.

       1   A session was reused.
