# NAME

SSL_session_reused - query whether a reused session was negotiated during handshake

# SYNOPSIS

    #include <openssl/ssl.h>

    int SSL_session_reused(const 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.
