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.
