SSL_set_session(3)                  OpenSSL                 SSL_set_session(3)

       SSL_set_session - set a TLS/SSL session to be used during TLS/SSL

       libcrypto, -lcrypto

        #include <openssl/ssl.h>

        int SSL_set_session(SSL *ssl, SSL_SESSION *session);

       SSL_set_session() sets session to be used when the TLS/SSL connection
       is to be established. SSL_set_session() is only useful for TLS/SSL
       clients.  When the session is set, the reference count of session is
       incremented by 1. If the session is not reused, the reference count is
       decremented again during SSL_connect(). Whether the session was reused
       can be queried with the SSL_session_reused(3) call.

       If there is already a session set inside ssl (because it was set with
       SSL_set_session() before or because the same ssl was already used for a
       connection), SSL_SESSION_free() will be called for that session. If
       that old session is still open, it is considered bad and will be
       removed from the session cache (if used). A session is considered open,
       if SSL_shutdown(3) was not called for the connection (or at least
       SSL_set_shutdown(3) was used to set the SSL_SENT_SHUTDOWN state).

       SSL_SESSION objects keep internal link information about the session
       cache list, when being inserted into one SSL_CTX object's session
       cache.  One SSL_SESSION object, regardless of its reference count, must
       therefore only be used with one SSL_CTX object (and the SSL objects
       created from this SSL_CTX object).

       The following return values can occur:

       0   The operation failed; check the error stack to find out the reason.

       1   The operation succeeded.
